Can not dismiss keyboard iOS. Nothing works

Question

I'm new in iOS Development for iPhone. I can not dismiss keyboard, nothing works. Please help me, maybe I didn't notice anything?

My .h file:

#import "UIKit/UIKit.h"

@interface ViewController : UIViewController <UITextViewDelegate>
@property (weak, nonatomic) IBOutlet UITextField *textField;
@end

My .m file:

#import "ViewController.h"
#import "UIKit/UIKit.h"

@interface ViewController ()

@end

@implementation ViewController

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}

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

Answer 1

Hi this is a simple mistake. You have not set the delegate. You can do this by..

- (void)viewDidLoad
{
    [super viewDidLoad];
    textField.delegate = self;
}

Answer 2

Please add textField.delegate = self; to your viewDidLoad.

Answer 3

Most likely you forgot to set the delegate for textField. Inside your storyboard or nib file, drag your UITextField's delegate to your ViewController.
