上傳圖片沒有響應任何

Question

這裏的問題：

1. 我要完成從imagepicker選擇圖像後，立即上傳圖片。

2. 於是，我把我的代碼上傳使用imagepicker委託方法afnetworking圖像。

3. 但它沒有任何反應。

   //set the imageview to current image after choosing 
   profilePic.image = image; 
   
   //dismiss the imagepicker 
   [picker dismissModalViewControllerAnimated:YES]; 
   
   //start upload image code 
   NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: 
            @"steventi1901", @"username", 
            UIImagePNGRepresentation(profilePic.image), @"profile_pic", 
            nil]; 
   
   AFHTTPClient *client = [[AFHTTPClient alloc] initWithBaseURL:updateProfile]; 
   NSData *imageToUpload = UIImagePNGRepresentation(profilePic.image); 
   
   NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"PUT" path:@"" parameters:params 
                 constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { 
       [formData appendPartWithFileData: imageToUpload name:@"file" fileName:@"temp.png" mimeType:@"image/png"]; 
       //NSLog(@"dalem"); 
   }]; 
   
   AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
   
   [operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) { 
       NSString *response = [operation responseString]; 
       NSLog(@"response: [%@]",response); 
   
   } failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
   
       if([operation.response statusCode] == 403){ 
        NSLog(@"Upload Failed"); 
        return; 
       } 
       NSLog(@"error: %@", [operation error]); 
   
   }]; 
   
   [operation start]; 
   //end upload image code 
   

它真的沒有任何反應，所以我不知道如果這個過程失敗或成功。

有你設置的選擇器的代表？

[yourPicker setDelegate:self]
