的UIButton沒有禁止使用setUserInteractionEnabled：NO和setEnabled：NO來

Question

下面是相關代碼的結構：

- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { 

    if(!isResponding) { 

    ... 

    else { 

    ... 

    [respondButton setUserInteractionEnabled:NO]; 
    [respondButton setEnabled:NO]; 

    [_manager POST:queryStringss parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
     [formData appendPartWithFileData:imageData name:@"file" fileName:usernameEncoded mimeType:@"image/jpeg"];} 
      success:^(AFHTTPRequestOperation *operation, id responseObject) { 

      ... 

      failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
       NSLog(@"Error: %@ ***** %@", operation.responseString, error); 

       ... 

      } 
     } 
    ]; 

    [respondButton setUserInteractionEnabled:YES]; 
    [respondButton setEnabled:YES]; 

    ... 

} 

我看，我不是重新啓用按鈕，不知道它，它永遠不會禁用。周圍的代碼運行。請幫忙，謝謝。

Answer 1

你應該在代碼塊內部移動你的代碼，它應該可以工作。您的網絡請求成功後啓用

[respondButton setUserInteractionEnabled:NO]; 
    [respondButton setEnabled:NO]; 

    [_manager POST:queryStringss parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
     [formData appendPartWithFileData:imageData name:@"file" fileName:usernameEncoded mimeType:@"image/jpeg"];} 
      success:^(AFHTTPRequestOperation *operation, id responseObject) { 

      ... 

      failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
       NSLog(@"Error: %@ ***** %@", operation.responseString, error); 

       ... 

      } 

      [respondButton setUserInteractionEnabled:YES]; 
      [respondButton setEnabled:YES]; 
     } 
    ]; 

Answer 2

開放用戶交互或失敗

[respondButton setUserInteractionEnabled:NO]; 
[respondButton setEnabled:NO]; 

[_manager POST:queryStringss parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
    [formData appendPartWithFileData:imageData name:@"file" fileName:usernameEncoded mimeType:@"image/jpeg"];} 
     success:^(AFHTTPRequestOperation *operation, id responseObject) { 

     ... 

     failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
      NSLog(@"Error: %@ ***** %@", operation.responseString, error); 
      [respondButton setUserInteractionEnabled:YES]; 
      [respondButton setEnabled:YES]; 

     } 
    } 
];

其他的答案是接近，但我還需要重新啓用在success塊太大的按鈕。

[respondButton setUserInteractionEnabled:NO]; 
[respondButton setEnabled:NO]; 

[_manager POST:queryStringss parameters:params constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
[formData appendPartWithFileData:imageData name:@"file" fileName:usernameEncoded mimeType:@"image/jpeg"];} 
    success:^(AFHTTPRequestOperation *operation, id responseObject) { 

     [respondButton setUserInteractionEnabled:YES]; 
     [respondButton setEnabled:YES]; 
    } 
    failure:^(AFHTTPRequestOperation *operation, NSError *error) { 

     [respondButton setUserInteractionEnabled:YES]; 
     [respondButton setEnabled:YES]; 

    } 
}];
