Swift 4和4.2版本:

 self.navigationController.navigationBar.titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.green]

又短又甜。

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

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);

我使用下面的代码为iOS 9和它的工作对我来说很好。我也使用阴影颜色的标题。

self.navigationItem.title = @"MY NAV TITLE";
self.navigationController.navigationBar.barTintColor = [UIColor redColor];
self.navigationController.navigationBar.translucent = NO;
NSShadow *shadow = [[NSShadow alloc] init];
shadow.shadowColor = [UIColor colorWithRed:0.0 green:0.0 blue:0.0 alpha:0.8];
shadow.shadowOffset = CGSizeMake(0, 1);
[self.navigationController.navigationBar setTitleTextAttributes: [NSDictionary dictionaryWithObjectsAndKeys:
                                                       [UIColor colorWithRed:245.0/255.0 green:245.0/255.0 blue:245.0/255.0 alpha:1.0], NSForegroundColorAttributeName,
                                                       shadow, NSShadowAttributeName,
                                                       [UIFont fontWithName:@"HelveticaNeue-Light" size:21.0], NSFontAttributeName, nil]];

希望这对你有所帮助。

谢谢

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];
    }
}

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;
