Question

I need to set custom colors to my UINavigationBar buttons.
I’m doing the following thing(RGB func is a define):

- (void)viewWillAppear:(BOOL)animated
{

for (UIView *view in self.navigationController.navigationBar.subviews)      
    if ([[[view class] description] isEqualToString:@"UINavigationButton"])
        [(UINavigationButton *)view setTintColor:RGB(22.0,38.0,111.0)];

 }

Everything looks fine on app load. after leaving the view and getting back the color returns to default.

Secondly I need to set the same colour to UISegmentedControl to a pressed button.

Answer 1

Here’s one way:

[[theNavigationBar.subviews objectAtIndex:1] setTitleColor:[UIColor redColor] forState:UIControlStateNormal];
[[theNavigationBar.subviews objectAtIndex:2] setTitleColor:[UIColor redColor] forState:UIControlStateNormal];

However, HUGE, caveat. This is highly likely to break on a future OS release and is not recommended.

At the very least you should perform a lot of testing and make sure you your assumptions of the subview layout of the navigation bar are correct.
or
You can change the color by changing the tintColor property of the UINavigationBar

myBar.tintColor = [UIColor greenColor];
