Question

我正在尝试使用AFNetwork上传一张NSData图像，但出现了问题我无法找到错误的地方

这是我的代码：

NSData *imageData = UIImageJPEGRepresentation([UIImage imageNamed:@"test.jpg"], 0.1);

NSMutableDictionary *postParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   @"this is only a test post for \"app\".", @"app",
                                   @"this POST for \"test\". ", @"test", nil];

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"http://url/upload.php" parameters:postParm constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
    [formData appendPartWithFileData:imageData name:@"file" fileName:@"filename.jpg" mimeType:@"image/jpeg" ];
} error:nil];

AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSProgress *progress = nil;

NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
    if (error) {
        NSLog(@"Error: %@", error);
    } else {
        NSLog(@"%@ %@", response, responseObject);
    }
}];

[uploadTask resume];

崩溃的结果如下：

任何想法在这里我的错误是什么..！？
