Question

我有一个UITextView（目的：注释）固定在我的屏幕底部，当用户想要添加评论时，键盘出现，我将评论视图与评论一起向上移动。我还有一个取消按钮来隐藏键盘，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];
}

我觉得这应该有效吗？正在将“cancelComment called”记录到控制台，但键盘未隐藏

Answer 1

<强> SOLUTION：

你忘记了：

repokey

你的cancelComment函数中的

。

Answer 2

你可以尝试

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

我认为你的textView不在self.view和self.navigationController.view

中

Answer 3

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [yourtextfieldname resignfirstresponder];
}

希望你能来这个！

键盘没有隐藏在ios中
