AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];    所有的网络请求,均有manager发起 2. 需要注意的是,默认提交请求的数据是二进制的,返回格式是JSON    1> 如果提交数据是JSON的,需要将请求格式设置为AFJSONRequestSerializer    2> 如果返回格式不是JSON的, 3. 请求格式     AFHTTPRequestSerializer            二进制格式     AFJSONRequestSerializer            JSON     AFPropertyListRequestSerializer    PList(是一种特殊的XML,解析起来相对容易) 4. 返回格式     AFHTTPResponseSerializer           二进制格式     AFJSONResponseSerializer           JSON     AFXMLParserResponseSerializer      XML,只能返回XMLParser,还需要自己通过代理方法解析     AFXMLDocumentResponseSerializer (Mac OS X)     AFPropertyListResponseSerializer   PList     AFImageResponseSerializer          Image     AFCompoundResponseSerializer       组合 */- (void)viewDidLoad{    [super viewDidLoad];
