Question

I use UINavigationbar, it works fine.

But now i have a paramater, which is global, to count the pushUIViewController for using popToUIViewController at index (index of screen i wanna be back). it worked but have an error when i click on UINavigation Left Button to get back to previous screen, this makes paramater continuing count (++).

then when i get back on the screen i expect the paramater had a different value.

How can I check if button of UINavigationbar is clicked or not???

Thanks in advance

Add button manually on navigation bar:

 UIButton *titleButton = [UIButton buttonWithType:UIButtonTypeCustom];
[titleButton setTitle:@"myTitle" forState:UIControlStateNormal];
titleButton.frame = CGRectMake(0, 0, 70, 44);
titleButton.font = [UIFont boldSystemFontOfSize:16];
[titleButton addTarget:self action:@selector(titleTap:) forControlEvents:UIControlEventTouchUpInside];
self.navigationItem.titleView = titleButton;

Add titleTap method to catch the tap event :

    - (IBAction) titleTap:(id) sender
{
    NSLog(@"Title tap");
}
