Change color of UINavigationBar

问题:

Hello,

I created UINavigationBar, and I try to change the color bar to aqua color (As in Nib file)

How do I do it?

回答1:

[[UINavigationBar appearance] setTintColor:[UIColor colorWithRed:0 green:.62 blue:.984 alpha:1]];

Dude, try this to get [UIColor Aqua] throughout your app.

回答2:

You can set either tintColor or backgroundImage to your UINavigationBar

- (void) viewDidLoad
{
   //set background image
   [self.navigationController.navigationBar setBackgroundImage:[UIImage imageNamed:@"background.png"]];

  //OR set background Color
  [self.navigationController.navigationBar setTintColor:[UIColor blueColor]];
}

I'm not sure but if you'll put this in first call method of your app it may apply everywhere!

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { }

try this,

UINavigationController *navigationController;
UIColor* aqua = [UIColor colorWithRed:0 green:1 blue:1 alpha:1];
navigationController.navigationBar.tintColor = [UIColor aqua];

回答4:

UINavigationBar *bar = [self.navigationController navigationBar];
[bar setTintColor:[UIColor colorWithRed:0.5 green:0.5 blue:0.5 alpha:1.0]];

Please try above code for set color.

Edited

 UINavigationBar *bar = [self.navigationController navigationBar];
UIColor* aqua = [UIColor colorWithRed:0 green:1 blue:1 alpha:1];
[bar setTintColor:aqua];

This Code use for the aqua color

回答5:

[self.navigationController.navigationBar setTintColor:[UIColor blueColor]];

Call this function befor the ViewController will appear, e.g. in viewDidLoad:
