【问题描述】：

我是 ios 开发的新手。我使用“AFNetworking”创建上传图像方法。我想在处理时添加UIProgressView。

现在我在上传方法中使用“DejalBezelActivityView” “DejalBezelActivityView”可以使用，但我想使用UIProgressView。

怎么做？

这是我的代码示例：

-(void) uploadImage

    // Set Data to Web API   
    // NSMutableArray *newPictureData = ...

    // WEB API
    [PictureClient uploadPictures:newPictureData whenCompleted:^(BOOL success, NSString *data, NSError *error)
    
         if (success)
         
              [DejalBezelActivityView removeViewAnimated:YES];
               UIAlertView *myAlertView = [[UIAlertView alloc] initWithTitle:@“Complete"
                                                                     message:@“Upload Cpmplete"
                                                                    delegate:self
                                                           cancelButtonTitle:@"OK"
                                                           otherButtonTitles:nil];
              [myAlertView show];

              // Do somethings
              // ...
         
         else
         
              [DejalBezelActivityView removeViewAnimated:YES];

              // Error                 
              UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@“Error"
                                                              message:errorCode
                                                             delegate:self
                                                    cancelButtonTitle:@"OK"
                                                    otherButtonTitles:nil];
              [alert show];                  
        
    ];

    [DejalBezelActivityView activityViewForView:self.view withLabel:@“During Picture"];

【参考方案1】：

喜欢@StatusReport answered 和MBHudProgress

// 1. Create `AFHTTPRequestSerializer` which will create your request.
AFHTTPRequestSerializer *serializer = [AFHTTPRequestSerializer serializer];

// 2. Create an `NSMutableURLRequest`.
NSMutableURLRequest *request =
    [serializer multipartFormRequestWithMethod:@"POST" URLString:@"http://www.myurl.com"
                                    parameters:dataToPost
                     constructingBodyWithBlock:^(id<AFMultipartFormData> formData) 
                       [formData appendPartWithFileData:imageData
                                                   name:@"attachment"
                                               fileName:@"myimage.jpg"
                                               mimeType:@"image/jpeg"];
                     ];

// 3. Create and use `AFHTTPRequestOperationManager` to create an `AFHTTPRequestOperation` from the `NSMutableURLRequest` that we just created.
AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
AFHTTPRequestOperation *operation =
    [manager HTTPRequestOperationWithRequest:request
                                     success:^(AFHTTPRequestOperation *operation, id responseObject) 
                                       [MBProgressHUD hideHUDForView:self.view animated:YES];
                                       NSLog(@"Success %@", responseObject);
                                      failure:^(AFHTTPRequestOperation *operation, NSError *error) 
                                       [MBProgressHUD hideHUDForView:self.view animated:YES];
                                       NSLog(@"Failure %@", error.description);
                                     ];

// 4. Set the progress block of the operation.
[operation setUploadProgressBlock:^(NSUInteger __unused bytesWritten,
                                    long long totalBytesWritten,
                                    long long totalBytesExpectedToWrite) 
  NSLog(@"Wrote %lld/%lld", totalBytesWritten, totalBytesExpectedToWrite);

];

// 5. Begin!
[operation start];
[MBProgressHUD showHUDAddedTo:self.view animated:YES];
