1.ASIHTTPRequest

虽然ASIHttpRequest已经很久没更新了，现在大家都在用AFNetWork，以前用习惯了，这次项目中用到了ASI断点下载的功能

 //初始化Documents路径        NSString *path = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];        //初始化临时文件路径        NSString *folderPath = [path stringByAppendingPathComponent:@"temp"];        //创建文件管理器        NSFileManager *fileManager = [NSFileManager defaultManager];        //判断temp文件夹是否存在        BOOL fileExists = [fileManager fileExistsAtPath:folderPath];                if (!fileExists) {//如果不存在就创建,因为下载时,不会自动创建文件夹            [fileManager createDirectoryAtPath:folderPath withIntermediateDirectories:YES attributes:nil error:nil];        }        //初始下载路径        NSURL *url = [[NSURL alloc]initWithString:urlString];        //设置下载路径        pdfRequest = [[ASIFormDataRequest alloc] initWithURL:url];        //设置ASIHTTPRequest代理        pdfRequest.delegate = self;        //初始化保存文件路径        NSString *savePath = [folderPath stringByAppendingPathComponent:[NSString stringWithFormat:@"test.pdf"]];        //初始化临时文件路径        NSString *tempPath = [path stringByAppendingPathComponent:[NSString stringWithFormat:@"temp/test.pdf"]];        //设置文件保存路径        [pdfRequest setDownloadDestinationPath:savePath];        //设置临时文件路径        [pdfRequest setTemporaryFileDownloadPath:tempPath];        //设置进度条的代理,        [pdfRequest setDownloadProgressDelegate:self];        //设置是是否支持断点下载        [pdfRequest setAllowResumeForFileDownloads:YES];                [pdfRequest setPostValue:[UserSingleton shareUserSingleton].letterId forKey:@"letterId"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].userId forKey:@"userId"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].archGroup forKey:@"archGroup"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].archVol forKey:@"archVol"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].archType forKey:@"archType"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].archStart forKey:@"archStart"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].tableTag forKey:@"tableTag"];        [pdfRequest setPostValue:[UserSingleton shareUserSingleton].status forKey:@"status"];        [pdfRequest startAsynchronous];

其中delegate方法如下：

//下载之前获取信息的方法,主要获取下载内容的大小- (void)request:(ASIHTTPRequest *)request didReceiveResponseHeaders:(NSDictionary *)responseHeaders{    [myTableView reloadData];    NSLog(@"didReceiveResponseHeaders-%@",[responseHeaders valueForKey:@"Content-Length"]);}//下载完成执行的方法- (void)requestFinished:(ASIHTTPRequest *)request{    //初始化网页所在的本地路径    NSString *path = [[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"]                      stringByAppendingPathComponent:[NSString stringWithFormat:@"test.pdf"]];    NSURL *url = [NSURL fileURLWithPath:path];    NSURLRequest *urlRequest = [NSURLRequest requestWithURL:url];    [myWebView loadRequest:urlRequest];    [progressView removeFromSuperview];     myWebView.frame = CGRectMake(0, 0, 320, [UIScreen mainScreen].bounds.size.height - 64 -80);}//下载失败- (void)requestFailed:(ASIHTTPRequest *)request{    [ALToastView toastInView:self.view withText:@"下载pdf失败"];}//下载进度- (void)setProgress:(float)newProgress{    NSLog(@"%f",newProgress);    [progressView setProgress:newProgress animated:YES];}

2.SWTableViewCell

SWTableviewCell，cell滑动可以出现多个编辑按钮，效果如图：

这个第三方库的下载地址：https://github.com/CEWendel/SWTableViewCell

需要说一下的就是，它有很多版本，目前发现只有0.2.7版本支持IOS6.0
