iPhone/Objective-C - 更改默认的"navigationItem.prompt"颜色

Question

有没有办法将self.navigationItem.prompt颜色设置为白色？目前它是黑色的.

这就是我现在设置navigationBar颜色的方法:

// Set top navigation bar.
UINavigationBar *bar = [navController navigationBar];
[bar setTintColor:[UIColor colorWithRed:180.0/255.0 green:25.0/255.0 blue:34.0/255.0 alpha:1]];
UIImageView *navBar = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
[navBar release];

..这就是我设置我的方式navigationItem.prompt:

self.navigationItem.prompt = @"Tap image for more options.";

Answer 1

它现在可以在iOS 5或更高版本中使用.试试这个代码.

[[UINavigationBar appearance] setTitleTextAttributes:
      [NSDictionary dictionaryWithObjectsAndKeys:
       [UIColor whiteColor], UITextAttributeTextColor, nil]];
