UIButton未使用setUserInteractionEnabled:NO和setEnabled:NO禁用

Question

下面是相关代码的结构：

- (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];

   ...

}

我已经看过了，我不会在不知情的情况下重新启用按钮，它永远不会禁用。运行周围的代码。请帮帮忙，谢谢。

Answer 1

你应该在代码块中移动你的代码，它应该可以工作。

 [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

打开网络请求成功或失败后启用的用户交互

[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];

       }
   }
];

其他答案都很接近，但我也需要在success块中重新启用该按钮。

[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];

   }
}];
