UISegmentedControl tintColor

I'm having problems getting UISegmentedControl to show the desired tint color.

// AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    // need red tint color in other views of the app
    [[UIView appearance] setTintColor:[UIColor redColor]];
    return YES;
}

// ViewController
- (void)viewDidLoad {
    [super viewDidLoad];
    NSArray *items = @[@"Item 1", @"Item 2"];
    UISegmentedControl *control = [[UISegmentedControl alloc] initWithItems:items];
    // would like to have this control to have a green tint color
    control.tintColor = [UIColor greenColor];
    [self.view addSubview:control];
}

How to make UISegmentedControl use the green tint color?
