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.
}

当我们在导航栏中插入一个按钮时，遇到了相同的问题(和其他人一样)，标签移动(在我的情况下，我有一个旋转器，当日期被加载时，我用一个按钮替换)，上述解决方案对我不起作用，所以这里是什么工作，并保持标签在同一位置一直:

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil

self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self)
{
    // this will appear as the title in the navigation bar
    //CGRect frame = CGRectMake(0, 0, [self.title sizeWithFont:[UIFont boldSystemFontOfSize:20.0]].width, 44);
   CGRect frame = CGRectMake(0, 0, 180, 44);
    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];
    self.navigationItem.titleView = label;
    label.text = NSLocalizedString(@"Latest Questions", @"");
    [label sizeToFit];
}

return self;

从ios5开始，我们必须使用titleTextAttribute字典(UInavigation控制器类引用中的预定义字典)设置标题文本的颜色和导航栏的字体。

 [[UINavigationBar appearance] setTitleTextAttributes:
 [NSDictionary dictionaryWithObjectsAndKeys:
  [UIColor blackColor],UITextAttributeTextColor, 
[UIFont fontWithName:@"ArialMT" size:16.0], UITextAttributeFont,nil]];

建议设置self。标题，因为这是用在推子导航栏或显示标签栏标题。

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // create and customize title view
        self.title = NSLocalizedString(@"My Custom Title", @"");
        UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectZero];
        titleLabel.text = self.title;
        titleLabel.font = [UIFont boldSystemFontOfSize:16];
        titleLabel.backgroundColor = [UIColor clearColor];
        titleLabel.textColor = [UIColor whiteColor];
        [titleLabel sizeToFit];
        self.navigationItem.titleView = titleLabel;
        [titleLabel release];
    }
}

又短又甜。

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

我已经自定义了导航栏的背景图像和左键项目，灰色标题不适合背景。然后我使用:

[self.navigationBar setTintColor:[UIColor darkGrayColor]];

将淡色改为灰色。现在标题是白色的!这就是我想要的。

也希望能有所帮助:)
