Change global tint color - iOS7/iOS8

Simply change the UIWindow 's tintColor in your application delegate, it's automatically passed as default to all its UIView descendants.

[self.window setTintColor:[UIColor greenColor]];

There are two ways to change your global tint color. As many mentioned above you could change self.window.tintColor in -application:didFinishLaunchingWithOptions:.

More elegant way, in my opinion, is to set Global Tint in File Inspector in your Storyboard while nothing is selected. This way your -application:didFinishLaunchingWithOptions: is cleaner.

Global Tint in File Inspector


You can specify a tint color for the entire app by setting the window’s tint property. To do this, you could use code similar to the following:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.tintColor = [UIColor purpleColor];
    return YES;
}

[[UIView appearance] setTintColor:[UIColor greenColor]];
