Question

I have a text field and a button. When the button is pressed, it calls a routine. I want the textfield end on exit to call the same routine without having to duplicate the code. ViewController.h is below

    #import <UIKit/UIKit.h>

@interface ViewController : UIViewController
@property (weak, nonatomic) IBOutlet UIWebView *webView;
@property (weak, nonatomic) IBOutlet UIActivityIndicatorView *activityind;
@property (weak, nonatomic) IBOutlet UITextField *search;

- (IBAction)calculate:(id)sender;

@end

Answer 1

In ViewController.h implement UITextFieldDelegate like so:

@interface ViewController : UIViewController <UITextFieldDelegate>

and then use the method

-(BOOL)textFieldShouldReturn:(UITextField *)textField

and call your IBAction and resignFirstResponder, I would also auto-enable return key.
