常见控件的总结

一、计步器和计数器

- (void)creatStepper{

//步进器、计数器

//事件驱动型

UIStepper *stepper = [[UIStepper alloc] initWithFrame:CGRectMake(100, 100, 100, 50)];

//设置默认色调

//stepper.tintColor = [UIColor redColor];

//设置最小值默认是0

stepper.minimumValue = 0;

//设置最大值默认是100

stepper.maximumValue = 1000;

//设置步长默认是1

stepper.stepValue = 10;

//设置长按之后是否可以连续触发函数

YES:长按的时候连续触发调用stepperClick:

NO:长按的时候的时候 stepperClick:最后松手调用一次

stepper.continuous = YES;

//长按的时候是否可以反复修改stepper的值

YES：可以连续的修改值

NO：不去连续改值长按的时候只改一次

stepper.autorepeat = YES;

//增加事件

[stepper addTarget:self action:@selector(stepperClick:) forControlEvents:UIControlEventValueChanged];

[self.view addSubview:stepper];

[stepper release];

}

- (void)stepperClick:(UIStepper *)stepper {

NSLog(@"value:%f",stepper.value);//打印当前的值

}

二、操作表单

需要遵守协议

@interface ViewController7 () <UIActionSheetDelegate>

@end

- (void)creatButton{

UIButton *button = [MyControl creatButtonWithFrame:CGRectMake(110, 100, 100, 50) target:self sel:@selector(btnClick:) tag:101 image:nil title:@"分享"];

[self.view addSubview:button];

}

- (void)btnClick:(UIButton *)button {

//操作表单

destructiveButtonTitle: 把一些危险的操作按钮写在这里会显示红色

UIActionSheet *sheet = [[UIActionSheet alloc] initWithTitle:@"分享" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"危险操作按钮" otherButtonTitles:@"短信分享",@"朋友圈分享",@"QQ分享" ,nil];

//从self.view上弹出

[sheet showInView:self.view];

[sheet release];

}

#pragma mark - UIActionSheetDelegate

//当点击actionSheet的按钮的时候通知代理调用处理

- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex {

//索引值从上至下从0开始

NSLog(@"index:%ld",buttonIndex);

}

三、分段控制器和时间驱动器

- (void)creatSegmentedControl{

//分段控制器

//事件驱动型

NSArray *titles = @[@"小红",@"小黄",@"屎壳郎"];

UISegmentedControl *seg = [[UISegmentedControl alloc] initWithItems:titles];

seg.frame = CGRectMake(10, 100, 300, 30);

//设置属性

//设置默认选中的分段

seg.selectedSegmentIndex = 0;

//增加标题分段

- (void)insertSegmentWithTitle:(NSString *)title atIndex:(NSUInteger)segment animated:(BOOL)animated;

//增加图片分段

- (void)insertSegmentWithImage:(UIImage *)image atIndex:(NSUInteger)segment animated:(BOOL)animated;

//删除指定

- (void)removeSegmentAtIndex:(NSUInteger)segment animated:(BOOL)animated;

//删除所有

- (void)removeAllSegments;

//增加图片分段显示原始图片

[seg insertSegmentWithImage:[[UIImage imageNamed:@"002"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal] atIndex:1 animated:YES];

//禁用指定分段

[seg setEnabled:NO forSegmentAtIndex:3];

//设置指定分段宽度0 自动设置设置宽

//[seg setWidth:40 forSegmentAtIndex:0];

//设置tintColor

seg.tintColor = [UIColor redColor];

//设置背景图片竖屏

[seg setBackgroundImage:[UIImage imageNamed:@"toolBar"] forState:UIControlStateNormal barMetrics:UIBarMetricsDefault];

//设置内容偏移量

//width >0 右偏移 height >0 向下偏移

[seg setContentOffset:CGSizeMake(5, 5) forSegmentAtIndex:0];

//更改属性字符串(修改内容字符串的颜色和大小)

NSDictionary *dict = @{NSFontAttributeName:[UIFont systemFontOfSize:20],NSForegroundColorAttributeName:[UIColor yellowColor]};

[seg setTitleTextAttributes:dict forState:UIControlStateNormal];

//增加事件点击分段值改变触发

[seg addTarget:self action:@selector(segClick:) forControlEvents:UIControlEventValueChanged];

[self.view addSubview:seg];

[seg release];

}

- (void)segClick:(UISegmentedControl *)seg {

//seg.selectedSegmentIndex 被点击的分段索引

//[seg titleForSegmentAtIndex:seg.selectedSegmentIndex]获取分段的标题

NSLog(@"index:%ld title:%@",seg.selectedSegmentIndex,[seg titleForSegmentAtIndex:seg.selectedSegmentIndex]);

}

四、警告视图

遵守协议<UIAlertViewDelegate>

@interface ViewController8 ()<UIAlertViewDelegate>

@end

- (void)creatAlertView{

//警告视图

NSArray *titles = @[@"普通",@"用户",@"密码",@"登录注册"];

for (NSInteger i = 0; i < titles.count; i++) {

UIButton *button = [MyControl creatButtonWithFrame:CGRectMake(110, 100+40*i, 100, 30) target:self sel:@selector(btnClick:) tag:101+i image:nil title:titles[i]];

[self.view addSubview:button];

}

- (void)btnClick:(UIButton *)button {

//四种不同风格的警告视图

UIAlertViewStyleDefault = 0,

UIAlertViewStyleSecureTextInput,

UIAlertViewStylePlainTextInput,

UIAlertViewStyleLoginAndPasswordInput

switch (button.tag) {

case 101://普通

{

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"警告" message:@"非法入侵" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

//设置类型

alertView.alertViewStyle = UIAlertViewStyleDefault;

alertView.tag = 201;

[alertView show];

[alertView release];

}

break;

case 102://用户

{

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"角色名称" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

//设置类型

alertView.alertViewStyle = UIAlertViewStylePlainTextInput;

alertView.tag = 202;

[alertView show];

[alertView release];

}

break;

case 103://密码

{

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"密码" message:nil delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定", nil];

//设置类型

alertView.alertViewStyle = UIAlertViewStyleSecureTextInput;

alertView.tag = 203;

[alertView show];

[alertView release];

}

break;

case 104://登录注册

{

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"登录" message:nil delegate:self cancelButtonTitle:@"登录" otherButtonTitles:@"注册", nil];

//设置类型

alertView.alertViewStyle = UIAlertViewStyleLoginAndPasswordInput;

alertView.tag = 204;

[alertView show];

[alertView release];

}

break;

default:

break;

}

#pragma mark - 代理方法

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex {

//通过tag区分alertView

//通过类型也区分不同类型的alertView

switch (alertView.alertViewStyle) {

case UIAlertViewStyleDefault:

{

NSLog(@"普通警告视图：%ld",buttonIndex);

}

break;

case UIAlertViewStylePlainTextInput:

{

//获取 alertView中textField

UITextField *text1 = [alertView textFieldAtIndex:0];

NSLog(@"用户:%@",text1.text);

}

break;

case UIAlertViewStyleSecureTextInput:

{

//获取 alertView中textField

UITextField *text1 = [alertView textFieldAtIndex:0];

NSLog(@"密码:%@",text1.text);

}

break;

case UIAlertViewStyleLoginAndPasswordInput:

{

UITextField *text1 = [alertView textFieldAtIndex:0];

NSLog(@"用户名:%@",text1.text);

UITextField *text2 = [alertView textFieldAtIndex:1];

NSLog(@"密码:%@",text2.text);

}

break;

default:

break;

}

五、菊花

- (void)creatAIV{

//UIActivityIndicatorView 活动指示器 -》菊花/风火轮

//普通的视图

UIActivityIndicatorViewStyleWhiteLarge,//大白

UIActivityIndicatorViewStyleWhite,//小白

UIActivityIndicatorViewStyleGray,//小灰

UIActivityIndicatorView *view = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];

view.frame = CGRectMake(100, 100, 100, 100);

//放到中间

view.center = self.view.center;

//默认必须转动才显示

//view.hidesWhenStopped = NO; 默认停止转动隐藏

//改变转动的颜色

view.color = [UIColor redColor];

[view startAnimating];

//2s之后停止菊花转动

//withObject:传得就是 click:的参数

[self performSelector:@selector(click:) withObject:view afterDelay:2];

//打开状态栏上的系统自带的网络小菊花

[UIApplication sharedApplication].networkActivityIndicatorVisible = YES;

[self.view addSubview:view];

[view release];

}

- (void)click:(UIActivityIndicatorView *)view {

if (view.isAnimating) {

[view stopAnimating];//停止转动

[UIApplication sharedApplication].networkActivityIndicatorVisible = NO;//关闭

}

六、文本输入框

- (void)creatUITextView{

//UITextField 只能输入一行

//iOS7之后滚动视图粘到带导航的视图上时，滚动视图的内容会自动向下偏移64像素,

//如果不想自动偏移那么我们需要取消导航的影响

self.automaticallyAdjustsScrollViewInsets = NO;

//或者

//self.edgesForExtendedLayout = UIRectEdgeNone;

//UITextView //文本输入多行 (可以滚动)

UITextView *textView = [[UITextView alloc] initWithFrame:CGRectMake(10, 100, 300, 200)];

textView.tag = 101;

//设置背景

textView.backgroundColor = [UIColor orangeColor];

//设置内容

textView.text = @"xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情xxxxxxx小红和小黄有激情";

//字体颜色

textView.textColor = [UIColor redColor];

//字体大小

textView.font = [UIFont systemFontOfSize:20];

//设置是否可以滚动

//textView.scrollEnabled = NO;

//设置是否可以编辑

//textView.editable = NO;

//设置代理

textView.delegate = self;

[self.view addSubview:textView];

[textView release];

}

//收键盘

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {

UITextView *text = (UITextView *)[self.view viewWithTag:101];

[text resignFirstResponder];

}

#pragma mark - UITextViewDelegate

//将要进入编辑模式的时候调用

- (BOOL)textViewShouldBeginEditing:(UITextView *)textView {

NSLog(@"%s",__func__);

return YES;//是否可以进入编辑模式

}

//已经进入编辑模式

- (void)textViewDidBeginEditing:(UITextView *)textView {

NSLog(@"%s",__func__);

}

//将要退出编辑模式调用

//决定是否可以结束编辑模式

- (BOOL)textViewShouldEndEditing:(UITextView *)textView {

NSLog(@"%s",__func__);

return YES;

}

//已经退出编辑模式

- (void)textViewDidEndEditing:(UITextView *)textView {

NSLog(@"%s",__func__);

}

//已经修改内容就会调用

//修改的时候一直调用

- (void)textViewDidChange:(UITextView *)textView {

NSLog(@"%s",__func__);

}

//只要修改或者选中就会调用

- (void)textViewDidChangeSelection:(UITextView *)textView {

NSLog(@"%s",__func__);

}

//将要把内容输入到 textView 的时候调用

//YES 表示可以输入到textView中 NO 不可以

//range 光标的位置 text ：将要输入的内容

- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text {

NSLog(@"range:%@ text:%@",NSStringFromRange(range),text);

return YES;

}

八、下载进度条

- (void)creatProgressView{

//进度条下载进度等

UIProgressView *proView = [[UIProgressView alloc] initWithFrame:CGRectMake(10, 100, 300, 30)];

//更改 progress就可以显示进度

//proView.progress = 0.5;

//更改轨道颜色

// proView.progressTintColor = [UIColor redColor];

//进度颜色

// proView.trackTintColor = [UIColor greenColor];

//模拟下载

//启动一个定时器每个1s 更改下载进度

//userInfo 给定时器触发的函数传入一个对象内部timer.userInfo获取

[NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(timerClick:) userInfo:proView repeats:YES];

[self.view addSubview: proView];

[proView release];

}

- (void)timerClick:(NSTimer *)timer {

//获取传入的值

UIProgressView *view = timer.userInfo;

if (view.progress < 1.0) {

view.progress += 0.1;

}else {

//下载完成终止定时器

[timer invalidate];

}

九、滑动条

- (void)creatSlider{

UISlider *slider = [[UISlider alloc] initWithFrame:CGRectMake(100, 200, 200, 30)];

//设置最小值

slider.minimumValue = 0;

//设置最大值

slider.maximumValue = 1;//默认是1

//设置轨道颜色

slider.minimumTrackTintColor = [UIColor redColor];

slider.maximumTrackTintColor = [UIColor yellowColor];

//设置最小值、最大值的图片

slider.minimumValueImage = [UIImage imageNamed:@"003"];

slider.maximumValueImage = [UIImage imageNamed:@"002"];

//设置小白球的图片

[slider setThumbImage:[UIImage imageNamed:@"003"] forState:UIControlStateNormal];//正常状态

[slider setThumbImage:[UIImage imageNamed:@"002"] forState:UIControlStateHighlighted];//高亮状态

//设置旋转修改 transform --》旋转 / 翻转 / 缩放

//相对于最原始的位置旋转-九十度

slider.transform = CGAffineTransformMakeRotation(-M_PI_2);

//长按是否连续触发事件函数

slider.continuous = YES;//NO长按滑动只触发一次 YES连续触发函数

//增加事件

[slider addTarget:self action:@selector(sliderClick:) forControlEvents:UIControlEventValueChanged];

[self.view addSubview:slider];

[slider release];

}

- (void)sliderClick:(UISlider *)sd {

NSLog(@"sd:%f",sd.value);//打印值

}

十、开关控件

//常见控件 1.普通视图2.事件驱动型控件(一般UIControl的子类)

- (void)creatView {

//开关 1.用设置界面

UISwitch *sw = [[UISwitch alloc] initWithFrame:CGRectMake(0, 100, 200, 50)];

//frame 只能改变位置不能改变实际大小 (系统有默认大小)

//iOS7之后没有效果设置开关大小边框的颜色

sw.tintColor = [UIColor grayColor];

//设置开得时候颜色

sw.onTintColor = [UIColor orangeColor];

//设置小白球颜色

sw.thumbTintColor = [UIColor purpleColor];

//iOS7之后无效果

//sw.onImage = [UIImage imageNamed:@"002"];

//sw.offImage = [UIImage imageNamed:@"002"];

//设置开关的默认状态开/关

sw.on = YES;

//增加事件

//当手指触发小球开关状态发生改变的时候调用

[sw addTarget:self action:@selector(swClick:) forControlEvents:UIControlEventValueChanged];

[self.view addSubview:sw];

[sw release];

}

//给谁增加的事件参数就是谁

//当手指触发小球开关状态发生改变的时候调用

- (void)swClick:(UISwitch *)sw {

NSLog(@"开关被触发%d",sw.on);//sw.on /sw.isOn 获取开关的状态

}
