当用户在textField外部点击时关闭键盘

Question

I'm trying to dismiss the keyboard when the user selects something other than the textFiled . I tried the following:

- (void)viewDidLoad {
    mytextField1.delegate = self;
    mytextFiled2.delegate = self;
}

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    [self.view endEditing:YES];    
}

This didn't work. I then tried [... resignFirstResponder] in touchesBagan , and that didn't work either. Am I doing something wrong? Why is this not working?

Answer 1

您是否尝试过在文本字段的超级视图上添加UITapGestureRecognizer以关闭键盘？

Answer 2

Add a tap gesture to the view (not the text field) so that you know when someone taps the view.

UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(viewTapped)];
[self.view addGestureRecognizer:tap];

Then when that method is called, resign first responder to dismiss the keyboard.

- (void)viewTapped
{
    if (self.textField.isFirstResponder) {
        [self.textField resignFirstResponder];
    }
}

Answer 3

You can use UITapGestureRecognizer. And also save the current focused TextField at activeTF. You need to set the current view controller as the delegate of UITextField(s).

UITextField *activeTF;

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view.

    .......

    UITapGestureRecognizer *dismissTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
    [self.view addGestureRecognizer:dismissTap];
}


- (void)dismissKeyboard {
    if (activeTF) {
        [activeTF resignFirstResponder];
    }
}

#pragma mark - TextField Delegate

-(void)textFieldDidBeginEditing:(UITextField *)sender
{
    activeTF = sender;
}

- (void)textFieldDidEndEditing:(UITextField *)sender
{
    activeTF = nil;
}
