键盘未隐藏在ios中

Question

我在屏幕底部固定了一个UITextView（用途：注释），当用户要添加注释时，键盘将出现，并且注释视图与注释一起向上移动。 我也有一个取消按钮来隐藏键盘，但是键盘没有隐藏

//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];
}

我觉得这应该工作吗？ “ cancelComment named”正在被记录到控制台，但是键盘没有被隐藏

Answer 1

解：

您忘了放：

[yourtextfield resignfirstresponder];

在您的cancelComment函数中。

Answer 2

你可以试试

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

我认为您不在self.view和self.navigationController.view中的textView

Answer 3

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

希望你能！
