You can recreate the titleView like that in your viewcontroller:
您可以在视图控制器中重新创建 titleView：
UILabel * titleView = [[UILabel alloc] initWithFrame:CGRectZero];
titleView.backgroundColor = [UIColor clearColor];
titleView.font = [UIFont boldSystemFontOfSize:20.0];
titleView.shadowColor = [UIColor colorWithWhite:1.0 alpha:1.0];
titleView.shadowOffset = CGSizeMake(0.0f, 1.0f);
titleView.textColor = [UIColor redColor]; // Your color here
self.navigationItem.titleView = titleView;
[titleView sizeToFit];
[titleView release];
the other parameters are those wich are used in the native titleView.
其他参数是在本机 titleView 中使用的参数。

[NSValue valueWithUIOffset:UIOffsetMake(-1, 0)], UITextAttributeTextShadowOffset, nil];
[[UINavigationBar appearance] setTitleTextAttributes:navbarTitleTextAttributes];

在 iOS 7 中，您可以通过以下方式更改导航栏标题/文本的颜色：

NSMutableDictionary *navBarTextAttributes = [NSMutableDictionary dictionaryWithCapacity:1];
