Question

I’ve tried all the answers I found on SO, so either I have a different problem or the heat got to my brain.

Anyway, I have a UIButton on a storyboard, it’s linked to an IBAction called _cameraButtonPress (the UIButton is called _cameraButton). When the button is pressed I want to disable the button for a time, so I immediately call [sender setEnabled:NO]; and this works fine. However, in a different function which saves out the image, on successful save I use [_cameraButton.setEnabled:YES]; This does not work.

If I replace sender with _cameraButton in the function called by the IBAction, this also does not work. I have the UIButton linked with an IBOutlet.

I can post code, but it’s quite a big project now, here are the relevant bits:

In the header…

IBOutlet UIButton *_cameraButton;

The IBAction…

- (IBAction) _cameraButtonPress:(id)sender {

[sender setEnabled:NO];  //stops button responding to touch events

Further on down in a different function:

} else {
    NSLog(@"colour image saved successfully");
    [_cameraButton setEnabled:YES];


}

Any ideas?

Thanks.

Are you sure you have connected _cameraButton with the UIButton? Try logging _cameraButton to see if it holds a reference to a valid object.

NSLog(@"%@", _cameraButton);
