Button press event not being fired

Chippie2002 · June 2012

Hi guys,

I'm playing with storyboards and have managed to construct the fallowing based off a tutorial....

My delegate header file

#import <UIKit/UIKit.h>
    
@interface ViewController : UIViewController
@property (nonatomic, retain) IBOutlet UITextView *label;
    
-(IBAction) my_btn:(id) sender;    
    
@end

Implementation file:


-(IBAction) my_btn:(id) sender
{
    self.label.text = @\"updated!\";
}

Now with the storyboard I have assigned the Touch drag outside > first responder to be linked to the my_btn action.
putting a breakpoint within this block doesn't get hit. Nor does my label get updated.

Can someone help please?

Unless Storyboard is different from how you do it in regular xib files, you should be assigning it to ViewController not first responder.

Hello Domele,

If it helps, I selected the button via storyboard and then from the "show connections inspector" panel I dragged the "Touch drag outside" to the View controller. It appears it only accepts the "first responder", but this clearly doesn't work. Am I doing something wrong? I've tried connecting it to the view controller but it doesn't seem to be valid.

your problem is the touch drag outside. Try touch up inside and check if it works. Your code also seems to be messed up if that is all of it. You need to specify the label as so:

@interface ViewController : UIViewController {
IBOutlet UITextView *label;
}
@property (nonatomic, retain) IBOutlet UITextView *label;

Then connect the label in the storyboard.

Howdy, Stranger!
