这是我基于史蒂文斯的解决方案

唯一真正的区别是，如果根据文本长度，我将一些处理用于调整位置，似乎与苹果的做法类似

UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(([self.title length] < 10 ? UITextAlignmentCenter : UITextAlignmentLeft), 0, 480,44)];
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.font = [UIFont boldSystemFontOfSize: 20.0f];
titleLabel.shadowColor = [UIColor colorWithWhite:0.0 alpha:0.5];
titleLabel.textAlignment = ([self.title length] < 10 ? UITextAlignmentCenter : UITextAlignmentLeft);
titleLabel.textColor = [UIColor redColor];
titleLabel.text = self.title;
self.navigationItem.titleView = titleLabel;
[titleLabel release];

您可能需要根据字体大小调整10值

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

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

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];
}

@end

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];

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。
