Disapperiang IPhone Numeric Keyboard

Question

How I can disappear numeric keyboard in iPhone because there is no return key in it, which implies it is not going to respond to

- (BOOL)textFieldShouldReturn:(UITextField *)textField

Answer 1

Use resignFirstResponder in touchesBegan, like so:

- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event {
    UITouch * touch = [touches anyObject];
    if(touch.phase == UITouchPhaseBegan) {
        [self.myTextField resignFirstResponder];
    }
}

You may need to call this on multiple text fields if you're not sure where the focus is currently located; I haven't tested that case.

Additionally, in Interface Builder, you'll need to enable the "User Interaction Enabled" checkbox for the view, or programatically use:

myView.userInteractionEnabled = YES;

Answer 2

Here's the answer..

-(void) touchesBegan :(NSSet *) touches withEvent:(UIEvent *)event

{

    //[URL resignFirstResponder];

    //[Password resignFirstResponder];

    [speedField resignFirstResponder];

    [super touchesBegan:touches withEvent:event ];

}

Answer 3

Try this:

[theTextField resignFirstResponder];

Answer 4

Why not to use "Numbers and Punctuation" keyboard instead of "Numeric"? It will save your time

Answer 5

Here you go. Extend your UIViewController Class with this. But how do we know it is the done button? Adding Done Button to Only Number Pad Keyboard on iPhone
