对于iOS 7的使用，上面的大多数建议现在都已弃用

NSDictionary *textAttributes = [NSDictionary dictionaryWithObjectsAndKeys: 
                               [UIColor whiteColor],NSForegroundColorAttributeName, 
                               [UIColor whiteColor],NSBackgroundColorAttributeName,nil];

self.navigationController.navigationBar.titleTextAttributes = textAttributes;
self.title = @"Title of the Page";

同样，签出NSAttributedString.h以获得可以设置的各种文本属性。

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;

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];
    }
}

要设置标题的字体大小，我使用了以下条件..也许对任何人都有帮助

if ([currentTitle length]>24) msize = 10.0f;
    else if ([currentTitle length]>16) msize = 14.0f;
    else if ([currentTitle length]>12) msize = 18.0f;

这是一个相当老的线程，但我认为提供的答案设置的颜色，大小和垂直位置的导航栏标题iOS 7及以上

颜色和尺寸

 NSDictionary *titleAttributes =@{
                                NSFontAttributeName :[UIFont fontWithName:@"Helvetica-Bold" size:14.0],
                                NSForegroundColorAttributeName : [UIColor whiteColor]
                                };

垂直位置

[[UINavigationBar appearance] setTitleVerticalPositionAdjustment:-10.0 forBarMetrics:UIBarMetricsDefault];

设置Title并分配属性字典

[[self navigationItem] setTitle:@"CLUBHOUSE"];
self.navigationController.navigationBar.titleTextAttributes = titleAttributes;

方法一，设置为IB:

方法二，一行代码:

navigationController?.navigationBar.barTintColor = UIColor.blackColor()
