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];
    }
}

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];

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。

titleTextAttributes 显示栏标题文本的属性。

NSDictionary *titleTextAttributes (nonatomic, copy 讨论 你可以在文本属性字典中为标题指定字体、文本颜色、文本阴影颜色和文本阴影偏移量，使用NSString UIKit添加参考中描述的文本属性键。

可用性 支持iOS 5.0及更高版本。 中声明 UINavigationBar.h

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:

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:)
