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;

self.navigationItem.title=@"Extras";
[self.navigationController.navigationBar setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"HelveticaNeue" size:21], NSFontAttributeName,[UIColor whiteColor],UITextAttributeTextColor,nil]];

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);

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];
    }
}

为了让Erik B的伟大解决方案在你的应用程序的不同UIViewController中更有用，我建议为UIViewController添加一个类别，并在里面声明他的setTitle:title方法。像这样，你将在所有视图控制器上得到标题颜色的改变，而不需要复制。

有一点需要注意的是，你不需要[super setTItle:tilte];在Erik的代码中，你需要显式地调用self。Title = @"my new Title "在你的视图控制器中用于这个方法被调用

@implementation UIViewController (CustomeTitleColor)

- (void)setTitle:(NSString *)title
{
    UILabel *titleView = (UILabel *)self.navigationItem.titleView;
    if (!titleView) {
        titleView = [[UILabel alloc] initWithFrame:CGRectZero];
        titleView.backgroundColor = [UIColor clearColor];
        titleView.font = [UIFont boldSystemFontOfSize:20.0];
        titleView.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];

        titleView.textColor = [UIColor blueColor]; // Change to desired color

        self.navigationItem.titleView = titleView;
        [titleView release];
    }
    titleView.text = title;
    [titleView sizeToFit];
}
