代码改变世界

iOS开发常用的第三方类库

2013-07-16 22:02 by 囧月, ... 阅读, ... 评论, 收藏, 编辑

在iOS开发中不可避免的会用到一些第三方类库,它们提供了很多实用的功能,使我们的开发变得更有效率;同时,也可以从它们的源代码中学习到很多有用的东西。

Reachability 检测网络连接

用来检查网络连接是否可用:包括WIFI和WWAN(3G/EDGE/CDMA等)两种工作模式。

可以从Apple网站下载到:http://developer.apple.com/library/ios/#samplecode/Reachability/History/History.html#//apple_ref/doc/uid/DTS40007324-RevisionHistory-DontLinkElementID_1

现在有更好的替代品:https://github.com/tonymillion/Reachability,比Apple提供的兼容性更好,而且更加好用,更具体的使用方法请看它提供的例子。

Reachability* reach = [Reachability reachabilityWithHostname:@"www.google.com"];
reach.reachableBlock = ^(Reachability*reach) {
    NSLog(@"网络可用!");
};
reach.unreachableBlock = ^(Reachability*reach) {
    NSLog(@"网络不可用!");
};
// 开始监听
[reach startNotifier];

 

ASIHTTPRequest 网络请求

ASIHTTPRequest是对CFNetwork API的一个包装,它提供了一套更加简洁的API,使用起来也更加简单。

官方网站:http://allseeing-i.com/ASIHTTPRequest/

GitHub:https://github.com/pokeb/asi-http-request

它不仅仅支持基本的HTTP请求,而且支持基于REST的服务(GET/POST/PUT/DELETE)。

最让人喜欢的是,它支持block语法:

   NSURL *url = [NSURL URLWithString:@"http://allseeing-i.com"];
   __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
   [request setCompletionBlock:^{
      // Use when fetching text data
      NSString *responseString = [request responseString];
 
      // Use when fetching binary data
      NSData *responseData = [request responseData];
   }];
   [request setFailedBlock:^{
      NSError *error = [request error];
   }];
   [request startAsynchronous];

它的ASIFormDataRequest子类可以横容易的提交表单数据和文件:

ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
[request setPostValue:@"Ben" forKey:@"first_name"];
[request setPostValue:@"Copsey" forKey:@"last_name"];
// Upload a file on disk
[request setFile:@"/Users/ben/Desktop/ben.jpg" withFileName:@"myphoto.jpg" andContentType:@"image/jpeg"
forKey:@"photo"]; 
// Upload an NSData instance
[request setData:imageData withFileName:@"myphoto.jpg" andContentType:@"image/jpeg" forKey:@"photo"];

详细的使用方法请下载相应的源代码及例子,或者从官方的使用说明http://allseeing-i.com/ASIHTTPRequest/How-to-use开始。

 

MBProgressHUD 提示效果

支持各种状态加载的提示效果,以及带进度的提示效果。

GitHub:https://github.com/matej/MBProgressHUD

一般会在.m文件实现MBProgressHUDDelegate协议,并声明HUD变量:

@interface SampleViewController ()<MBProgressHUDDelegate>
{
    MBProgressHUD *HUD;
}
#pragma mark -
#pragma mark MBProgressHUDDelegate methods

- (void)hudWasHidden:(MBProgressHUD *)hud {
	// Remove HUD from screen when the HUD was hidded
	[HUD removeFromSuperview];
	HUD = nil;
}

在执行某个异步请求时开始调用:

    HUD = [MBProgressHUD showHUDAddedTo:self.webView animated:YES];
    HUD.labelText = @"正在请求...";
    // mode参数可以控制显示的模式
    //HUD.mode = MBProgressHUDModeText;
    HUD.delegate = self;

请求完成时隐藏提示效果:

[HUD hide:YES];

对于同步方法一般都是用showWhileExecuting方法,方法执行完成之后会自动隐藏提示效果:

[HUD showWhileExecuting:@selector(myTask) onTarget:self withObject:nil animated:YES];

 

SVProgressHUD 提示效果

GitHub:https://github.com/samvermette/SVProgressHUD

SVProgressHUD和MBProgressHUD效果差不多,不过不需要使用协议,同时也不需要声明实例。

直接通过类方法进行调用即可:

[SVProgressHUD method]

可以使用以下方法来显示状态:

+ (void)show;
+ (void)showWithMaskType:(SVProgressHUDMaskType)maskType;
+ (void)showWithStatus:(NSString*)string;
+ (void)showWithStatus:(NSString*)string maskType:(SVProgressHUDMaskType)maskType;

如果需要明确的进度,则使用以下方法:

+ (void)showProgress:(CGFloat)progress;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status;
+ (void)showProgress:(CGFloat)progress status:(NSString*)status maskType:(SVProgressHUDMaskType)maskType;

通过dismiss方法来隐藏提示:

+ (void)dismiss;

另外提供了以下方法用于显示状态,并在1秒后自动隐藏提示(使用的图标来源于Glyphish:http://www.glyphish.com/):

+ (void)showSuccessWithStatus:(NSString*)string;
+ (void)showErrorWithStatus:(NSString *)string;
+ (void)showImage:(UIImage*)image status:(NSString*)string; // use 28x28 white pngs

 

ZAActivityBar 提示效果

GitHub:https://github.com/zacaltman/ZAActivityBar

ZAActivityBar和SVProgressHUD非常相似,它提供了更加简洁的API来显示提示效果。

ZAActivityBar使用的动画效果来源于ZKBounceAnimation(https://github.com/khanlou/SKBounceAnimation),成功、失败的状态图标来源于Pictos(http://pictos.cc/)。

显示加载状态:

[ZAActivityBar showWithStatus:@"加载中..."];

显示成功、失败状态:

[ZAActivityBar showSuccessWithStatus:@"成功!"];
[ZAActivityBar showErrorWithStatus:@"失败!"];

隐藏提示:

[ZAActivityBar dismiss];

 

SBJson JSON解析

官方: http://sbjson.org/

GitHub:https://github.com/stig/json-framework

API使用起来稍显繁琐,特别是初始化的时候:

@interface TestViewController ()<SBJsonStreamParserAdapterDelegate> {
    SBJsonStreamParser *parser;
    SBJsonStreamParserAdapter *adapter;
}

// 冗长的初始化方法足以吓到一大片人
- (void)initSBJSON
{
    // We don't want *all* the individual messages from the
	// SBJsonStreamParser, just the top-level objects. The stream
	// parser adapter exists for this purpose.
	adapter = [[SBJsonStreamParserAdapter alloc] init];
	
	// Set ourselves as the delegate, so we receive the messages
	// from the adapter.
	adapter.delegate = self;
	
	// Create a new stream parser..
	parser = [[SBJsonStreamParser alloc] init];
	
	// .. and set our adapter as its delegate.
	parser.delegate = adapter;
	
	// Normally it's an error if JSON is followed by anything but
	// whitespace. Setting this means that the parser will be
	// expecting the stream to contain multiple whitespace-separated
	// JSON documents.
	parser.supportMultipleDocuments = YES;
}

#pragma mark SBJsonStreamParserAdapterDelegate methods

- (void)parser:(SBJsonStreamParser *)parser foundArray:(NSArray *)array {
    [NSException raise:@"unexpected" format:@"Should not get here"];
}

- (void)parser:(SBJsonStreamParser *)parser foundObject:(NSDictionary *)dict {
    NSLog(@"SBJson parser foundObject");
    // 处理返回的数据
}

// 使用ASIHTTPRequest请求测试
- (void) loadData {
    __block ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:url];
    [request setRequestMethod:@"POST"];
    [request setCompletionBlock:^{
        // Use when fetching text data
        //NSString *responseString = [request responseString];
        // Use when fetching binary data
        NSData *responseData = [request responseData];
        NSLog(@"Connection didReceiveData of length: %u", responseData.length);
        
        // Parse the new chunk of data. The parser will append it to
        // its internal buffer, then parse from where it left off in
        // the last chunk.
        SBJsonStreamParserStatus status = [parser parse:responseData];
        
        if (status == SBJsonStreamParserError) {
            NSLog(@"Parser error: %@", parser.error);
        } else if (status == SBJsonStreamParserWaitingForData) {
            NSLog(@"Parser waiting for more data");
        }
    }];
    [request setFailedBlock:^{
        NSError *error = [request error];
        NSLog(@"failed - %@ %@", [error localizedDescription], error);
    }];
    [request startAsynchronous];
}

 

JSONKit JSON解析

GitHub:https://github.com/johnezang/JSONKit

提供比SBJson更优异的性能以及更加简便的使用方法,但是中文最好使用utf-8格式(\uXXXX),否则容易造成乱码。

API调用起来非常简单,省去了SBJson那么一大堆的方法:

JSONDecoder* decoder = [[JSONDecoder alloc] initWithParseOptions:JKParseOptionNone];
id result = [decoder objectWithData:jsonData];

详细的使用方法请看它的GitHub主页。

 

SDWebImage 图片异步加载及缓存

SDWebImage用于异步下载网络上的图片,并支持对图片的缓存等。

多数情况下是使用UIImageView+WebCache为UIImageView异步加载图片:

#import <SDWebImage/UIImageView+WebCache.h>
// ...
[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
                   placeholderImage:[UIImage imageNamed:@"placeholder.png"]];

需要注意的是,pladeholderImage的大小一定要大于UIImageView的大小,否则可能不显示placeholderImage图片。

它还支持block语法用于在加载完成时做一些操作:

[cell.imageView setImageWithURL:[NSURL URLWithString:@"http://www.domain.com/path/to/image.jpg"]
               placeholderImage:[UIImage imageNamed:@"placeholder.png"]
                      completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType) {... completion code here ...}];

SDWebImage并不局限于UIImageView上,使用SDWebImageManager完成更多的操作:

SDWebImageManager *manager = [SDWebImageManager sharedManager];
[manager downloadWithURL:imageURL
                 options:0
                 progress:^(NSUInteger receivedSize, long long expectedSize)
                 {
                     // 下载进度
                 }
                 completed:^(UIImage *image, NSError *error, SDImageCacheType cacheType)
                 {
                     if (image)
                     {
                         // 下载完成
                     }
                 }];

或者使用Image Downloader也是一样的效果:

[SDWebImageDownloader.sharedDownloader downloadImageWithURL:imageURL
        options:0
       progress:^(NSUInteger receivedSize, long long expectedSize)
       {
           // 进度
       }
       completed:^(UIImage *image, NSData *data, NSError *error, BOOL finished)
       {
           if (image && finished)
           {
               // 下载完成
           }
       }];

 

UIActivityIndicator-for-SDWebImage 为SDWebImage显示加载效果

GitHub:https://github.com/JJSaccolo/UIActivityIndicator-for-SDWebImage

用于为SDWebImage在UIImageView加载图片时,显示加载效果(UIActivityIndicatorView实现),它提供以下方法:

- (void)setImageWithURL:(NSURL *)url usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options progress:(SDWebImageDownloaderProgressBlock)progressBlock completed:(SDWebImageCompletedBlock)completedBlock usingActivityIndicatorStyle:(UIActivityIndicatorViewStyle)activityStyle;

 

UIImage+Resize 调整图片大小

GitHub:https://github.com/coryalder/UIImage_Resize

提供多种方法为图片设置透明度、圆角、裁剪、调整大小等:

- (UIImage *)imageWithAlpha;
- (UIImage *)transparentBorderImage:(NSUInteger)borderSize;
- (UIImage *)roundedCornerImage:(NSInteger)cornerSize borderSize:(NSInteger)borderSize;
- (UIImage *)croppedImage:(CGRect)bounds;
- (UIImage *)thumbnailImage:(NSInteger)thumbnailSize
          transparentBorder:(NSUInteger)borderSize
               cornerRadius:(NSUInteger)cornerRadius
       interpolationQuality:(CGInterpolationQuality)quality;
- (UIImage *)resizedImage:(CGSize)newSize
     interpolationQuality:(CGInterpolationQuality)quality;
- (UIImage *)
  resizedImageWithContentMode:(UIViewContentMode)contentMode
                       bounds:(CGSize)bounds
         interpolationQuality:(CGInterpolationQuality)quality;

更详细使用见:http://vocaro.com/trevor/blog/2009/10/12/resize-a-uiimage-the-right-way/

注意:这种方法调整图片大小有可能会产生图片模糊失真问题(因为不同设备的scale导致)

这里有一个更简单的方法(http://stackoverflow.com/questions/6141298/how-to-scale-down-a-uiimage-and-make-it-crispy-sharp-at-the-same-time-instead):

- (UIImage *)resizeImage:(UIImage*)image newSize:(CGSize)newSize {
    CGRect newRect = CGRectIntegral(CGRectMake(0, 0, newSize.width, newSize.height));
    CGImageRef imageRef = image.CGImage;

    UIGraphicsBeginImageContextWithOptions(newSize, NO, 0);
    CGContextRef context = UIGraphicsGetCurrentContext();

    // Set the quality level to use when rescaling
    CGContextSetInterpolationQuality(context, kCGInterpolationHigh);
    CGAffineTransform flipVertical = CGAffineTransformMake(1, 0, 0, -1, 0, newSize.height);

    CGContextConcatCTM(context, flipVertical);  
    // Draw into the context; this scales the image
    CGContextDrawImage(context, newRect, imageRef);

    // Get the resized image from the context and a UIImage
    CGImageRef newImageRef = CGBitmapContextCreateImage(context);
    UIImage *newImage = [UIImage imageWithCGImage:newImageRef];

    CGImageRelease(newImageRef);
    UIGraphicsEndImageContext();    

    return newImage;
}

 

ImageCacheResize 异步加载图片、缓存及调整大小

GitHub:https://github.com/toptierlabs/ImageCacheResize

整合了SDWebImage和UIImage+Resize的功能,用于图片的异步加载、缓存、以及下载完成后调整大小并显示在UIImageView上。

提供了以下API用于加载图片以及加载完成后调整图片大小:

- (void)setImageWithURL:(NSURL *)url andCropToBounds:(CGRect)bounds;
- (void)setImageWithURL:(NSURL *)url andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder andCropToBounds:(CGRect)bounds;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andResize:(CGSize)size withContentMode:(UIViewContentMode)mode;
- (void)setImageWithURL:(NSURL *)url placeholderImage:(UIImage *)placeholder options:(SDWebImageOptions)options  andCropToBounds:(CGRect)bounds;

使用方法和SDWebImage一样简单,如以下官方例子:

[imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andResize:CGSizeMake(30, 30) withContentMode:UIViewContentModeScaleAspectFit]; // 按比例缩放
[imageview setImageWithURL:[NSURL URLWithString:@"http://t0.gstatic.com/images?q=tbn:ANd9GcQfraHpiabjEY8iDdBe9OUQYHMtwfuAv9ZRR0RYKuoVF_EpE8Fp5A"] andCropToBounds:CGRectMake(0, 0, 100, 100)]; // 裁剪成100x100大小

 

EGOTableViewPullRefresh  下拉刷新

GitHub:https://github.com/enormego/EGOTableViewPullRefresh

这是最早出现的为UITableView提供下拉刷新功能的类库,使用起来稍显麻烦,需要实现诸多协议(代码取自官方DEMO):

#import "EGORefreshTableHeaderView.h"

@interface RootViewController : UITableViewController  <EGORefreshTableHeaderDelegate, UITableViewDelegate, UITableViewDataSource>{
	EGORefreshTableHeaderView *_refreshHeaderView;
	//  是否正在加载中 
	BOOL _reloading;
}

- (void)viewDidLoad {
    [super viewDidLoad];
    
	if (_refreshHeaderView == nil) {
		EGORefreshTableHeaderView *view = [[EGORefreshTableHeaderView alloc] initWithFrame:CGRectMake(0.0f, 0.0f - self.tableView.bounds.size.height, self.view.frame.size.width, self.tableView.bounds.size.height)];
		view.delegate = self;
		[self.tableView addSubview:view];
		_refreshHeaderView = view;
		[view release];
	}
	//  更新最后加载时间
	[_refreshHeaderView refreshLastUpdatedDate];
}

#pragma mark -
#pragma mark Data Source Loading / Reloading Methods

- (void)reloadTableViewDataSource{
	//  在这里加入代码用于获取数据
	_reloading = YES;
}

- (void)doneLoadingTableViewData{
	//  数据加载完成时调用这个方法
	_reloading = NO;
	[_refreshHeaderView egoRefreshScrollViewDataSourceDidFinishedLoading:self.tableView];
}

#pragma mark -
#pragma mark UIScrollViewDelegate Methods

- (void)scrollViewDidScroll:(UIScrollView *)scrollView{	
	[_refreshHeaderView egoRefreshScrollViewDidScroll:scrollView];
}

- (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate{
	[_refreshHeaderView egoRefreshScrollViewDidEndDragging:scrollView];
}

#pragma mark -
#pragma mark EGORefreshTableHeaderDelegate Methods

- (void)egoRefreshTableHeaderDidTriggerRefresh:(EGORefreshTableHeaderView*)view{
	[self reloadTableViewDataSource];
	[self performSelector:@selector(doneLoadingTableViewData) withObject:nil afterDelay:3.0];
}

- (BOOL)egoRefreshTableHeaderDataSourceIsLoading:(EGORefreshTableHeaderView*)view{
	return _reloading; // should return if data source model is reloading
}

- (NSDate*)egoRefreshTableHeaderDataSourceLastUpdated:(EGORefreshTableHeaderView*)view{
	return [NSDate date]; // should return date data source was last changed
}

 

PullToRefresh 下拉刷新

GitHub:https://github.com/leah/PullToRefresh

PullToRefresh提供比EGOTableViewPullRefresh更加简单的使用方法,只要继承自PullRefreshTableViewController,再实现refresh方法即可:

- (void)refresh {
    // 加载数据

    [self.tableView reloadData]; // 重新载入UITableView
    [self stopLoading]; //停止动画
}

 

STableViewController  下拉刷新、上拉加载更多

GitHub:https://github.com/shiki/STableViewController

STableViewController比PullToRefresh多了一个上拉加载更多功能,使用上也差不多简单,需要继承自STableViewController,再实现一些方法:

- (void) viewDidLoad
{
  [super viewDidLoad];
  
  self.title = @"STableViewController Demo";
  [self.tableView setBackgroundColor:[UIColor lightGrayColor]];
  
  // 需要创建两个自定义视图用于显示"下拉刷新"、"上拉加载更多"
  self.headerView = headerView;  
  self.footerView = footerView;  
}

#pragma mark - Pull to Refresh
- (void) pinHeaderView
{
  [super pinHeaderView];
  
  // 下拉刷新视图显示一些加载动画
}
- (void) unpinHeaderView
{
  [super unpinHeaderView];
  
  // 下拉刷新视图停止动画
}
- (void) headerViewDidScroll:(BOOL)willRefreshOnRelease scrollView:(UIScrollView *)scrollView
{
  // 下拉刷新视图显示状态信息
  if (willRefreshOnRelease)
    //hv.title.text = @"松开后刷新...";
  else
    //hv.title.text = @"下拉刷新...";
}

- (BOOL) refresh
{
  if (![super refresh])
    return NO;
  
  // 下拉刷新加载数据
  [self performSelector:@selector(addItemsOnTop) withObject:nil afterDelay:2.0];
  return YES;
}

#pragma mark - Load More
- (void) willBeginLoadingMore
{
  // 上拉加载更多视图加载动画
}
- (void) loadMoreCompleted
{
  [super loadMoreCompleted];
  // 上拉加载更多视图停止动画
  
  if (!self.canLoadMore) {
    //没有更多数据的时候执行代码...
  }
}

- (BOOL) loadMore
{
  if (![super loadMore])
    return NO;
  
  // 上拉加载更多数据
  [self performSelector:@selector(addItemsOnBottom) withObject:nil afterDelay:2.0];
  return YES;
}

// 
- (void) addItemsOnTop
{
  // 加载数据...
  
  [self.tableView reloadData];  
  // 数据加载完成通知上拉视图
  [self refreshCompleted];
}

- (void) addItemsOnBottom
{
  // 加载更多数据...
  [self.tableView reloadData];
  
  // 通过判断设置是否可以加载更多
  //self.canLoadMore = NO;  
  // 数据加载完成通知下拉视图
  [self loadMoreCompleted];
}

 

SVPullToRefresh 下拉刷新、上拉加载更多

GitHub:https://github.com/samvermette/SVPullToRefresh

包含SVPullToRefresh + SVInfiniteScrolling为UITableView提供下拉刷新、上拉加载更多功能。

使用起来也相当简单,只要在UITableViewController里实现以下方法:

- (void)viewDidLoad {
    [super viewDidLoad];

    __weak SVViewController *weakSelf = self;
    
    // 设置下拉刷新
    [self.tableView addPullToRefreshWithActionHandler:^{
        [weakSelf insertRowAtTop];
    }];
        
    // 设置上拉加载更多
    [self.tableView addInfiniteScrollingWithActionHandler:^{
        [weakSelf insertRowAtBottom];
    }];
}

- (void)viewDidAppear:(BOOL)animated {
    [tableView triggerPullToRefresh];
}

- (void)insertRowAtTop {
    // 获取数据....
    
    // 停止动画
    [self.tableView.pullToRefreshView stopAnimating];
}

- (void)insertRowAtBottom {
    // 获取数据....
    
    // 停止动画
    [weakSelf.tableView.infiniteScrollingView stopAnimating];
}

 

CMPopTipView 提示信息

GitHub:https://github.com/chrismiles/CMPopTipView

self.tipView = [[CMPopTipView alloc] initWithMessage:@"提示消息"];
self.tipView.delegate = self;
[self.tipView presentPointingAtView:anyButton inView:self.view animated:YES]; // 点击按钮显示
[self.tipView presentPointingAtBarButtonItem:barButtonItem animated:YES]; // 点击导航栏按钮显示
    
#pragma mark CMPopTipViewDelegate methods
- (void)popTipViewWasDismissedByUser:(CMPopTipView *)popTipView {
  // 清理资源
  self.tipView = nil;
}
