how to hide keyboard in UIViewController on return button click->iphone

Hi I find some questions like that but they talk about textView, I have ViewController, with scrollView where are 6 textfield and one textView I want a function which makes the keyboard disappear on on done/return button cl开发者_开发技巧ick.I implemented functions resign to first responder, which hide my keyboard when i click outside of scrollView, but that is not exactly i want, because i like to make it disappear on button click too.

THanks for any help

Set up a class that conforms to the UITextFieldDelegate protocol and make the delegate of your text fields an instance of this class. Implement the method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField

As follows:

- (BOOL)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
    return YES;
}

Hi i found it out so the point with textfields is to add this lines at viewdidload:

textFieldOne.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
textFieldTwo.returnKeyType = UIReturnKeyDone;
    textFieldCislo.delegate = self;
...

And this implement method :

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

    if (theTextField == textFieldOne) {
        [textFieldOne resignFirstResponder];
    }
...
}

U can use this method to hide the keyboard by clicking any where in the view

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

After quite a bit of time hunting down something that makes sense, this is what I put together and it worked like a charm.

    // _theTextField is the name of the parameter designated in the .h file.

    [_theTextField setDelegate:self];

}

// This part is more dynamic as it closes any text field when pressing return.  
// You might want to control every single text field separately but that isn't 
// what this code do.
-(void)textFieldShouldReturn:(UITextField *)textField
{
    [textField resignFirstResponder];
}
