Question

How to set an outlet on an UIBarButtonItem. I have programmatically maked this button and now i can not connect the outlet. Is there a code for connecting outlets?

Making the button:

UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.frame = CGRectMake(0, 0, 50, 28);
[button setImage:[UIImage imageNamed:@"donebutton.png"] forState:UIControlStateNormal];
[button addTarget:self action:@selector(releaseKeyboard) forControlEvents:UIControlEventTouchUpInside];

UIBarButtonItem *barButton1 = [[UIBarButtonItem alloc] init];
[barButton1 setCustomView:button];
self.navigationItem.rightBarButtonItem = barButton1;

Selector:

-(void)releaseKeyboard {

[text resignFirstResponder];

}

Where the problem is:

-(void)keyboardWillHide:(NSNotification *)aNotification {

    NSLog(@"Keyboard hide");
    barButton.enabled = NO;
}

barButton is not connected to an outlet, because i can’t select anything in the IB.

Answer 1

Yeah, so instead of

barButton.enabled = NO;

use

self.navigationItem.rightBarButtonItem.enabled = NO;

That’s because you don’t own the reference to barButton1 anymore (you’re in another function — another context), let alone barButton.
