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);

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

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。

在任何视图控制器viewDidLoad或viewWillAppear方法中使用下面的代码。

- (void)viewDidLoad
{
    [super viewDidLoad];

    //I am using UIColor yellowColor for an example but you can use whatever color you like   
    self.navigationController.navigationBar.titleTextAttributes = @{NSForegroundColorAttributeName: [UIColor yellowColor]};

    //change the title here to whatever you like
    self.title = @"Home";
    // Do any additional setup after loading the view.
}

又短又甜。

[[[self navigationController] navigationBar] setTitleTextAttributes:@{NSForegroundColorAttributeName: [UIColor redColor]}];

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:
