How to change the text color on UINavigationBar button items

Question

I\'ve got a UINavigationController and i\'ve changed it to white using the Tint property of the navigation bar in Interface Builder. But the text in buttons and the title is

Answer 1

you can change title appearance by adding label into the navigation bar like bellow.

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 100, 35)];
label.backgroundColor = [UIColor clearColor];
label.textAlignment = UITextAlignmentCenter;
label.textColor =[UIColor whiteColor];
label.text=self.title;
self.navigationItem.titleView = viewLabel;
[label release]; 

Answer 2

Here the clean way (relying on public API) to do this IMHO : you should use the titleView property of the navigationItem to apply it your own UILabel on which you will customize the textColor

UILabel* lbl = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 320, 20)];
lbl.textAlignment=UITextAlignmentCenter;
lbl.backgroundColor=[UIColor clearColor];
lbl.textColor=[UIColor colorWithRed:0.18 green:0.2 blue:0.56 alpha:1];
theControllerOnWhichYouWantToHaveATitleWithYourOwnColor.navigationItem.titleView=lbl;
[lbl release];

Answer 3

for (id subView in theNavigationBar.subviews) {
    if ([subView isKindOfClass:[UIButton class]]) {
        [(UIButton *)subView setTitleColor:[UIColor blackColor] forState:UIControlStateNormal];
        [(UIButton *)subView setTitleShadowColor:[UIColor clearColor] forState:UIControlStateNormal];
    }

}

Answer 4

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.

Answer 5

Or you use your own button bar item subclass with a setter you specify, lus isn't iPhone os 3 suppose to exposé text color for EVERY button

Answer 6

Can't you iterate the contents of the UINavigationBar view to find the buttons in the awakeFromNib?
