Question

Is it possible using the UIAppearance proxy (in iOS 5) to change the background colour of iOS Elements, specifically the tab bars and title bars without using images?

I’d like to use a deep green gradient, but without using images. Is it possible to do so in both iOS 5 and below?

Answer 1

Well you’re asking two different questions here, but if you want to simply change the tint color it can be done like this…

self.navigationController.navigationBar.tintColor = [UIColor colorWithRed:255 green:0 blue:0 alpha:1];
self.tabBarController.tabBar.tintColor = [UIColor colorWithRed:255 green:0 blue:0 alpha:1];

Additionally, if you wish to use a gradient this is possible to do without imagery, but is best done with a tiled image…

self.navigationController.navigationBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"myGradient.png"]];
self.tabBarController.tabBar.tintColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"myGradient.png"]];
