我们都知道，如果用storyBoard设置导航栏很容易，点击左右item的时候，进入下一个界面，导航栏的颜色是跟上一层的是一样的，用纯代码写的时候，可以在当前控制器，和从当前控制器进入到下一个控制器都用代码实现对导航栏的控制，但是，每次都写代码设置，很麻烦，所以，可以这样：
创建一个MainTabBarController的类，在Appdelegate.m里面完成：
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.window.rootViewController = [[MainTabBarController alloc] init];
[self.window makeKeyAndVisible];
return YES;
}
然后，在MainTabBarController.m里面
- (void)viewDidLoad {
[super viewDidLoad];
[self setUpAllChildVc];
}
- (void)setUpAllChildVc
{
//有几个界面，设置几个
MapViewController *HomeVC = [[HFMapViewController alloc] init];
[self setUpOneChildVcWithVc:HomeVC Image:@"地图-首页" selectedImage:@"地图选中-首页" title:@"地图"];
AppointmentViewController *appointmentVC = [[HFAppointmentViewController alloc] init];
[self setUpOneChildVcWithVc:appointmentVC Image:@"预约-首页" selectedImage:@"预约选中-首页" title:@"预约"];
}
- (void)setUpOneChildVcWithVc:(UIViewController *)Vc Image:(NSString *)image selectedImage:(NSString *)selectedImage title:(NSString *)title
{
MainNavigationController *nav = [[MainNavigationController alloc] initWithRootViewController:Vc];
UIImage *myImage = [UIImage imageNamed:image];
myImage = [myImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
//tabBarItem，是系统提供模型，专门负责tabbar上按钮的文字以及图片展示
Vc.tabBarItem.image = myImage;
UIImage *mySelectedImage = [UIImage imageNamed:selectedImage];
mySelectedImage = [mySelectedImage imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
Vc.tabBarItem.selectedImage = mySelectedImage;
Vc.tabBarItem.title = title;
[self addChildViewController:nav];
}
只要需要导航栏的，都可以把当前控制器设置为MainNavigationController的跟试图控制器
ios 用纯代码写程序的时候，navigationController的导航栏的设置
