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];
    }
}

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。

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;

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.
}

像这样使用定向支持

UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0,0,320,40)];
[view setBackgroundColor:[UIColor clearColor]];
[view setAutoresizingMask:UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight ];

UILabel *nameLabel = [[UILabel alloc] init];
[nameLabel setFrame:CGRectMake(0, 0, 320, 40)];
[nameLabel setBackgroundColor:[UIColor clearColor]];
[nameLabel setAutoresizingMask:UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin |UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin];
[nameLabel setTextColor:[UIColor whiteColor]];
[nameLabel setFont:[UIFont boldSystemFontOfSize:17]];
[nameLabel setText:titleString];
[nameLabel setTextAlignment:UITextAlignmentCenter];
[view addSubview:nameLabel];
[nameLabel release];
self.navigationItem.titleView = view;
[view release];

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];
    }
}
