ios - 键盘未隐藏在 ios 中

Question

我在屏幕底部固定了一个 UITextView(用途:评论)，当用户想要添加评论时，键盘出现，我让评论 View 随着评论一起向上移动。我还有一个隐藏键盘的取消按钮，但键盘没有隐藏

//Set up NSNotification for Keyboard
-(void) viewWillAppear:(BOOL)animated
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillToggle:)
                                             name:UIKeyboardWillShowNotification object:nil];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillToggle:)
                                             name:UIKeyboardWillHideNotification object:nil];
}

//Code to shift comment view up with keyboard
 - (void) keyboardWillToggle:(NSNotification *)aNotification
{
    CGRect frame = [self.navigationController.toolbar frame];
    CGRect keyboard = [[aNotification.userInfo valueForKey:@"UIKeyboardFrameEndUserInfoKey"] CGRectValue];
    frame.origin.y = keyboard.origin.y - frame.size.height;
    [UIView animateWithDuration:[[aNotification.userInfo valueForKey:@"UIKeyboardAnimationDurationUserInfoKey"] floatValue] animations:^
  {
     [self.navigationController.toolbar setFrame:frame];
 }];
}


//Hide keyboard
-(void)cancelComment:(UIBarButtonItem*)sender{
    NSLog(@"cancelComment called");
    [self.view endEditing:YES];
}

我觉得这应该行得通？ “cancelComment called”正在记录到控制台，但键盘未隐藏

解决方案:

你忘了放:

[yourtextfield resignfirstresponder];

在您的 cancelComment 函数中。
