以编程方式退出iPhone键盘

Question

In my create profile I have only two text fields: weight and date of birth. When the user touches for weight the keyboard shows. But when the user touches the date of birth a date picker appears in the action sheet. When the user selects the date and press the done button the action sheet disappears but the keyboard remains open. And there is no way to hide this keyboard. I have used resignFirstResponder method but no luck.

Answer 1

要隐藏键盘时，需要执行以下操作：

[textfield resignFirstResponder];

Answer 2

Did you include the method :

-(BOOL) textFieldShouldReturn:(UITextField *)textField{

    [textField resignFirstResponder];
    return YES;
}

or

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
    UITouch *touch = [[event allTouches] anyObject];
    if ([txtComment isFirstResponder] && [touch view] != txtComment)
    {
        [txtComment resignFirstResponder];
    }
    [super touchesBegan:touches withEvent:event];
}

Answer 3

[[[UIApplication sharedApplication] keyWindow] endEditing:YES]; will work for you.

Answer 4

-(void) ViewDidLoad
{

 // your some codes

   UITapGestureRecognizer *gestureRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideKeyboard)];
   [self.view addGestureRecognizer:gestureRecognizer];
   gestureRecognizer.cancelsTouchesInView = NO;
}

- (void) hideKeyboard 
{
    [textfiledname1 resignFirstResponder];
    [textfieldname2 resignFirstResponder];
}
