如果你试图改变一个页面的颜色，tewha的解决方案效果很好，但我希望能够改变每个页面的颜色。我做了一些小的修改，使它可以工作在UINavigationController上的所有页面

NavigationDelegate.h

//This will change the color of the navigation bar
#import <Foundation/Foundation.h>
@interface NavigationDelegate : NSObject<UINavigationControllerDelegate> {
}
@end

NavigationDelegate.m

#import "NavigationDelegate.h"
@implementation NavigationDelegate

- (void)navigationController:(UINavigationController *)navigationController 
      willShowViewController:(UIViewController *)viewController animated:(BOOL)animated{
    CGRect frame = CGRectMake(0, 0, 200, 44);//TODO: Can we get the size of the text?
    UILabel* label = [[[UILabel alloc] initWithFrame:frame] autorelease];
    label.backgroundColor = [UIColor clearColor];
    label.font = [UIFont boldSystemFontOfSize:20.0];
    label.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
    label.textAlignment = UITextAlignmentCenter;
    label.textColor = [UIColor yellowColor];
    //The two lines below are the only ones that have changed
    label.text=viewController.title;
    viewController.navigationItem.titleView = label;
}
@end

为了保持问题的最新，我将添加Alex R. R.解决方案，但在Swift中:

self.navigationController.navigationBar.barTintColor = .blueColor()
self.navigationController.navigationBar.tintColor = .whiteColor()
self.navigationController.navigationBar.titleTextAttributes = [
    NSForegroundColorAttributeName : UIColor.whiteColor()
]

结果是:

在IOS 7和8中，你可以将标题的颜色改为绿色

self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObject:[UIColor greenColor] forKey:NSForegroundColorAttributeName];

我遇到了一个问题，我的导航按钮将文本抛出中心(当你只有一个按钮时)。为了解决这个问题，我改变了我的帧大小，如下所示:

CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);

Swift 4和4.2版本:

 self.navigationController.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.green]

这是我们缺失的东西之一。您最好的办法是创建自己的自定义导航栏，添加一个文本框，并以这种方式操作颜色。
