Question

In IOS4.3 if I set

navigationBar.tintColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:1];

Answer 1

Ive had this issue before 4.2, i think colourWithRed:Green:blue allocates a new UIColor object which your responsible for managing.

The solution is to create an instance for your tint colour and release it when your done with your navigation controller in viewDidUnload.

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    tintBarColor = [UIColor   
                colorWithRed:50.0/255   
                green:134.0/255   
                blue:187.0/255   
                alpha:1];
    self.navigationController.navigationBar.tintColor = tintBarColor;
}

- (void)viewDidUnload
{
    [super viewDidUnload];
    [tintBarColor release];
    // Relinquish ownership of anything that can be recreated in viewDidLoad or on     demand.
    // For example: self.myOutlet = nil;
}
