项目总结

 

1.获取调用者所在视图控制器的类名

NSString *className = [NSString stringWithUTF8String:class_getName([self class])];

2.UIPopoverController的用法

引入头文件：

。h

《UIPopoverControllerDelegate 》

。m

UIPopoverController *_popover = [[UIPopoverController alloc] initWithContentViewController:_reportListViewController];
    _popover.delegate = self;
    [_popover setPopoverContentSize:CGSizeMake(330,330)];
    _reportListViewController.contentSizeForViewInPopover=_reportListViewController.view.bounds.size;
    [_popover presentPopoverFromRect:button.frame inView:self.view permittedArrowDirections:UIPopoverArrowDirectionLeft
                            animated:YES];
    
    [_reportListViewController release];

实现代理方法：

- (void)popoverControllerDidDismissPopover:(UIPopoverController *)popoverController
{
    if (popoverController) {
        [popoverController dismissPopoverAnimated:YES];
        [popoverController release];
        popoverController=nil;
    }
}

3.本地化

    NSUserDefaults *userDefaults = [NSUserDefaults standardUserDefaults];
    NSMutableArray *historyList = [NSMutableArray arrayWithArray:[userDefaults  arrayForKey:kReportHistory]];

　　/*中间存数据*/

  　[userDefaults synchronize];

　　                 go on...

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *filePath = [NSString stringWithFormat:@"%@/%@.pdf", documentsDirectory, [dict objectForKey:kReportID]];
    
    // 判断报告文件是否存在
    NSFileManager *fileManager = [NSFileManager defaultManager];
    if([fileManager fileExistsAtPath:filePath])
    {
        // 打开本地报告文件
        NSString *phrase = nil;
        ReaderDocument *document = [ReaderDocument withDocumentFilePath:filePath password:phrase];
        if (document != nil)
        {

　　　　：：：Pdf Reader类库打酱油：：：
            ReaderViewController *readerViewController = [[[ReaderViewController alloc] initWithReaderDocument:document] autorelease];
            readerViewController.delegate = self;
            [readerViewController setMainToolBarTitle:[dict objectForKey:kReportTitle]];
            readerViewController.modalTransitionStyle = UIModalTransitionStyleCrossDissolve;
            readerViewController.modalPresentationStyle = UIModalPresentationFullScreen;
            [self presentModalViewController:readerViewController animated:YES];
        }
        else
        {
            hint(@"打开报告文件失败！请重试！");
        }
    }
　　else
    {
        // 下载报告文件
        [self hint:@"该报告还未下载，是否现在下载？" trueBlock:^{
            downloadReportIndex = reportIndex;
            sIndexPath = indexPath;
            
            _HUD = [[MBProgressHUD showHUDAddedTo:_reportList animated:YES] retain];
            _HUD.delegate = self;
            _HUD.labelText = @"网络连接中...";
            _HUD.minSize = CGSizeMake(135.f, 135.f);
            
            ASIHTTPRequest *request = [ASIHTTPRequest requestWithURL:[NSURL URLWithString:url]];
            request.queue = self;
            [request setDownloadDestinationPath:filePath];
            [request startAsynchronous];
        }];

　　}
