关于AFNetworking上传图片问题

AFNetworking上传图片

AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    [manager POST:@"XXXX"  parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        NSData *imageData = UIImageJPEGRepresentation(_userImg, 1);
 
        // 上传图片，以文件流的格式 name 对应网站上[upload.php中]处理文件的[字段"file"] fileName 不能为空且必须带后缀，如：test.jpg
        [formData appendPartWithFileData:imageData name:@"photo" fileName:@"XXXX.jpg" mimeType:@"image/jpeg"];

     } success:^(AFHTTPRequestOperation *operation, id responseObject) {
        [_activityView stopAnimating];
        if ([[responseObject objectForKey:@"success"] intValue] == YES) {
            [self makeToast:@"头像修改成功！" duration:2.0 position:@"bottom"];
            [self saveUserInfo:[responseObject objectForKey:@"data"] key:@"avatar"];
        }else{
            id data = [responseObject objectForKey:@"data"];
            [self makeToast:[data objectForKey:@"message"] duration:2.0 position:@"bottom"];
        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        [_activityView stopAnimating];
        [self makeToast:@"网络不给力!" duration:2.0 position:@"bottom"];
    }];

特别注意注释行！
