Issue of tintColor for navigation bar in iOS 4 and iOS 5

Question

I have set tint color for navigation bar like

self.navigationController.navigationBar.tintColor = 
    [UIColor colorWithRed:168.0/255.0 green:0.0/255.0 blue:0.0/255.0 alpha:1.0];

This works in iOS 5 and above. But in iOS 4 and below iOS 5 its just black color. The tint color is not set.

Answer 1

for UISWitch tintColor is only for IOS 6.0 and later. so probably on IOS 5.0 should crash
