How to make return key on iPhone make keyboard disappear?
First you need to conform to the UITextFieldDelegate Protocol in your View/ViewController's header file like this:
@interface YourViewController : UIViewController <UITextFieldDelegate>Then in your .m file you need to implement the following UITextFieldDelegate protocol method:
- (BOOL)textFieldShouldReturn:(UITextField *)textField{ [textField resignFirstResponder]; return YES;}[textField resignFirstResponder]; makes sure the keyboard is dismissed.
Make sure you're setting your view/viewcontroller to be the UITextField's delegate after you init the textfield in the .m:
yourTextField = [[UITextField alloc] initWithFrame:yourFrame];//....//....//Setting the textField's properties//.... //The next line is important!!yourTextField.delegate = self; //self references the viewcontroller or view your textField is on
Implement the UITextFieldDelegate method like this:
- (BOOL)textFieldShouldReturn:(UITextField *)aTextField{ [aTextField resignFirstResponder]; return YES;}
