Hi Greg,
Thanks for this information. It did change the color of the TabBar.
But the other question is still unanswered. Is it possible to change
the TabBarItem's image colors? Instead of default gray (when not selected)
and blue (when selected)? How?
Thanks! Really appreciate it!
Regards,
Angie

There is no API for changing the UITabBar. Yet, you can subclass the TabBarController and override the viewDidLoad method. For example,
@interface UITabBarController (private)
- (UITabBar *)tabBar;
@end
@implementation CustomUITabBarController
- (void)viewDidLoad {
[super viewDidLoad];
CGRect frame = CGRectMake(0.0, 0.0, self.view.bounds.size.width, 48);
UIView *v = [[UIView alloc] initWithFrame:frame];
[v setBackgroundColor:[UIColor redColor]];
[v setAlpha:0.5];
[[self tabBar] addSubview:v];
[v release];
}
@end
This would set a red tint to the tab bar. Check on stackoverflow.com for many more examples. Keep in mind the above example modifies the tabBar of the controller, which is specifically mentioned in the documentation not to mess with. So, use at your own risk.
Greg
