推荐答案

我也遇到了这个问题，并且没有 throttleBandwithWithPacketSize 方法的运气。我相信在我的情况下，这是一个身份验证挑战问题。

I was experiencing this issue also and didn't have any luck with the throttleBandwithWithPacketSize method. I believe in my case it was an authentication challenge issue.

我最后要做的是切换到AFNetworking 2.0中的URLSession连接方法，这似乎为我解决了这一问题。这是我最终使用的代码：

What I finally did was switch to the URLSession connection method in AFNetworking 2.0 and that seemed to solve it for me. Here is the code I ended up using:

    NSString *uploadAttachmentURL = @"https://mydomain.zendesk.com/api/v2/uploads.json?filename=screenshot.jpeg";

    NSData *imageData = UIImageJPEGRepresentation(image, 1.0);

    NSURLSessionConfiguration *configuration = [NSURLSessionConfiguration defaultSessionConfiguration];
    _afHTTPSessionManager = [[AFHTTPSessionManager alloc] initWithSessionConfiguration:configuration];

    // hack to allow 'text/plain' content-type to work
    NSMutableSet *contentTypes = [NSMutableSet setWithSet:_AFOpManager.responseSerializer.acceptableContentTypes];
    [contentTypes addObject:@"text/plain"];
    _afHTTPSessionManager.responseSerializer.acceptableContentTypes = contentTypes;

    [_afHTTPSessionManager.requestSerializer setAuthorizationHeaderFieldWithUsername:@"[USERNAME]" password:@"[PASSWORD]"];



    [_afHTTPSessionManager POST:uploadAttachmentURL parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
        [formData appendPartWithFileData:imageData name:@"screenshot" fileName:@"photo.jpg" mimeType:@"image/jpeg"];
    } success:^(NSURLSessionDataTask *task, id responseObject) {
        DDLogError(@"screenshot operation success!  %@", responseObject);
    } failure:^(NSURLSessionDataTask *task, NSError *error) {
        DDLogError(@"Operation Error: %@", error);
    }];
