演示Demo.gif - 在AppDelegate.m内设置窗口启动根控制器
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 1.创建窗口
self.window = [[UIWindow alloc]initWithFrame:[UIScreen mainScreen].bounds];
// 2.设置窗口的根控制器
WYTabBarController *tabBarVC = [[WYTabBarController alloc]init];
self.window.rootViewController = tabBarVC;
// 3.显示窗口
[self.window makeKeyAndVisible];
return YES;
}
- 在WYTabBarController.m内创建并添加子控制器
- (void)viewDidLoad {
[super viewDidLoad];
//添加所有子控制器方法
[self setUpAllChildViewController];
}
/**
* 添加所有子控制器方法
*/
- (void)setUpAllChildViewController{
NSMutableDictionary *attrs = [NSMutableDictionary dictionary];
attrs[NSFontAttributeName] = [UIFont systemFontOfSize:12];
attrs[NSForegroundColorAttributeName] = [UIColor grayColor];
NSMutableDictionary *selectedAttrs = [NSMutableDictionary dictionary];
selectedAttrs[NSFontAttributeName] = attrs[NSFontAttributeName];
selectedAttrs[NSForegroundColorAttributeName] = [UIColor darkGrayColor];
UITabBarItem *item = [UITabBarItem appearance];
[item setTitleTextAttributes:attrs forState:UIControlStateNormal];
[item setTitleTextAttributes:selectedAttrs forState:UIControlStateSelected];
// 1.添加第一个控制器
WYOneViewController *oneVC = [[WYOneViewController alloc]init];
[self setUpOneChildViewController:oneVC image:@"tabBar_essence_icon" selectedImage:@"tabBar_essence_click_icon" title:@"第一"];
// 2.添加第2个控制器
WYTwoViewController *twoVC = [[WYTwoViewController alloc]init];
[self setUpOneChildViewController:twoVC image:@"tabBar_friendTrends_icon" selectedImage:@"tabBar_friendTrends_click_icon" title:@"第二"];
// 3.添加第3个控制器
WYThreeViewController *threeVC = [[WYThreeViewController alloc]init];
[self setUpOneChildViewController:threeVC image:@"tabBar_me_icon" selectedImage:@"tabBar_me_click_icon" title:@"第三"];
}
/**
* 封装子控制器的方法
*/
- (void)setUpOneChildViewController:(UIViewController *)viewController image:(NSString *)image selectedImage:(NSString *)selectedImage title:(NSString *)title{
viewController.tabBarItem.title = title;
viewController.navigationItem.title = title;
viewController.tabBarItem.image = [UIImage imageNamed:image];
viewController.tabBarItem.selectedImage = [UIImage imageNamed:selectedImage];
UINavigationController *navC = [[UINavigationController alloc]initWithRootViewController:viewController];
[self addChildViewController:navC];
}
//代码实现不被渲染的方法
//在Assets图片里，已经设置图片不被渲染成蓝色
//这里的代码就不必使用了
//-(UIImage *)RenderingWithString:(NSString *)imageNameString{
// UIImage *image = [UIImage imageNamed:imageNameString];
// //不被渲染
// image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
//
// return image;
//}
