Close the keyboard on UITextField

Question

I'm a newbie developing for iOS devices. I inserted an UITextField on InterfaceBuilder, and I assigned with the code:

 @interface ComposeViewController : UIViewController {  id <ComposeViewControllerDelegate> delegate;  IBOutlet UITextField *notificationTitle; } 

How I could allow to close the keyboard when the user press the "Return" key?

Answer 1

Set the Delegate of the UITextField to your ViewController, add a referencing outlet between the File's Owner and the UITextField, then implement this method:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {    if (textField == yourTextField) {        [textField resignFirstResponder];    }    return NO; } 

Answer 2

Inherit UITextFieldDelegate protocol In viewDidLoad method set:

yourTextField.delegate = self 

Implement the delegate method below:

- (BOOL)textFieldShouldReturn:(UITextField *)textField {     [yourTextField resignFirstResponder];    return NO; }
