在 iOS 中打开键盘时发送按钮不起作用

Question

我被困在 iOS 中非常简单的功能中。

我正在尝试从滚动视图的子视图内的文本字段发送数据。当我按下按钮时按钮正在触发动作，当我尝试写东西时键盘关闭并且键盘打开按钮停止响应时。

VideoViewController:

-(void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:animated];

   controller.videoID = videoID;
   controller.channelID = channelID;

   controller.view.frame = self.commentView.bounds;

   [self.commentView addSubview:controller.view];

   // [self.scrollView addSubview:controller.sendBtn];

   [self addChildViewController:controller];

   [controller didMoveToParentViewController:self];
}

评论视图控制器：

-(void)viewWillAppear:(BOOL)animated
{
   [super viewWillAppear:animated];

   controller.videoID = videoID;
   controller.channelID = channelID;

   controller.view.frame = self.commentView.bounds;

   [self.commentView addSubview:controller.view];

    // [self.scrollView addSubview:controller.sendBtn];

   [self addChildViewController:controller];

   [controller didMoveToParentViewController:self];
}

-(void)keyboardWillShow:(NSNotification *)notification
{

    CGSize keyboardSize = [[[notification userInfo] objectForKey:UIKeyboardFrameBeginUserInfoKey] CGRectValue].size;

   [UIView animateWithDuration:0.3 animations:^{
    CGRect f = self.view.frame;
    f.origin.y = -keyboardSize.height+100;
    self.sendView.frame = f;
    }];
    _sendBtn.userInteractionEnabled = YES;
}

-(void)keyboardWillHide:(NSNotification *)notification
{
  [UIView animateWithDuration:0.3 animations:^{
    CGRect f = self.view.frame;
    f.origin.y = 0.0f;
    self.sendView.frame = f;
    }];
}
-(BOOL)textFieldShouldReturn:(UITextField *)textField
{
   [commentTextField resignFirstResponder];
   return YES;
}
- (BOOL)touchesShouldCancelInContentView:(UIView *)view
{
   return ![view isKindOfClass:[UIButton class]];
}

请就此提出建议。谢谢。

我也遇到过这个问题

我花了 2 天时间才找到解决方案。您需要将 ScrollVIew/View.

的取消触摸标志设置为 false

实际上，scrollview touch是启用的，它不允许按钮交互。

这是发送按钮不起作用的唯一原因。
