图片的上传 这里是用第三方AFNetWorking
-(viod)updata{UIApplication *application = [UIApplication sharedApplication];AFHTTPRequestOperationManager *manager =[AFHTTPRequestOperationManager manager];
manager.requestSerializer.timeoutInterval = 5;
manager.responseSerializer.acceptableContentTypes = [NSSet setWithObjects:@"text/plain",@"text/javascript",@"text/html", @"application/json",nil];NSArray*arrar=[THE_IMG_PATH componentsSeparatedByString:@"/"];
NSString*imageName=[arrar objectAtIndex:arrar.count-1];
NSMutableDictionary*dic=@{@"image":_imageString,@"imagePath":imageName};[manager POST:urlString parameters:dic success:^(AFHTTPRequestOperation *operation, id responseObject) {if(sucess){sucess(responseObject);NSLog(@"responseObject=%@",responseObject);
}} failure:^(AFHTTPRequestOperation *operation, NSError *error) {NSLog(@"LYYB----AFNetWoring.errno=%@",error); fails(error);}];
