Yeah, I noticed long ago, (Xcode 4.3?) that the text I had entered in the
storyboards for the name of the back button no longer was obeyed in the screens
that I created. Maybe it was iOS 6, but I forget.
Today, I create the a UIBarButtonItem with a title and set it to the
self.navigationIdem.leftBarButtonItem using a GCD dispatch_after.
I tried doing it directly, but the UI would wait for 20 seconds before it took,
so I used a GDC dispatch and it gets the job done.
Here is is in a little method for you. You can modify it to pass in the
selector so that it's more general purpose.
Notice the commented out line below the closing paren. Try commenting out the
dispatch and using that instead and watch as your UI takes 20 seconds to update.
- (void) createBackbuttonWithTitle (NSString *)buttonTitle {
UIBarButtonItem *leftButton = [[UIBarButtonItem alloc]
initWithTitle:NSLocalizedString(buttonTitle, nil)
style:UIBarButtonItemStyleDone target:self action:@selector(dismiss:)];
dispatch_after(dispatch_time(DISPATCH_TIME_NOW, .5 * NSEC_PER_MSEC),
dispatch_get_main_queue(),
^{
self.navigationItem.leftBarButtonItem = leftButton;
});
// self.navigationItem.leftBarButtonItem = leftButton;
}
Hope this helps ya out.
