Disapperiang IPhone Numeric Keyboard - iphone

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

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
