Programmatically created a button on iOS, but no action when pressed

Question

I created a button just like the code below, but it will not respond in the log (supposed to show "ha"). The strangest part is that I have been able to get this exact code to work inside a collection view, but not normally on a viewcontroller. What am I doing wrong with the button press "myAction"? ``` -(void)viewDidLoad { UIButton *buttonz = [UIButton buttonWithType:UIButtonTypeCustom]; buttonz.frame = CGRectMake(160, 0, 160, 30); [buttonz setTitle:@"Charge" forState:UIControlStateNormal]; [buttonz addTarget:self action:@selector(myAction:) forControlEvents:UIControlEventTouchUpInside]; [buttonz setEnabled:YES]; [buttonz setBackgroundColor:[UIColor blueColor]]; //add the button to the view [backImageView addSubview:buttonz]; } -(void)myAction:(id)sender { NSLog(@"ha"); [self resignFirstResponder]; NSLog(@"ha"); } ```

Accepted Answer

1)

You don't need to "`resignFirstResponder`" on a button (seems like most of the time I see "`resignFirstResponder`" is in text fields or text views).

2)

Change the control event from UIControlEventTouchUpInside to UIControlEventTouchDown

3)

The parent UIImageView might not have "`userInteractionEnabled`" set to true, which means events won't be propogated (or sent along) to subviews.

To make those events available to subviews, change the parent view's userInteractionEnabled property via:

```
backImageView.userInteractionEnabled = YES;
```

before adding that subview.
