新建一个继承UITabbar的类
- (void)viewDidLoad {
[super viewDidLoad];
LFHomeTableViewController *home=[[LFHomeTableViewController alloc]init];
[self addChildVC:home Title:@"首页" image:@"tabbar_home" selectedImage:@"tabbar_home_selected"];
LFMessageTableViewController *discover=[[LFMessageTableViewController alloc]init];
[self addChildVC:discover Title:@"消息" image:@"tabbar_message_center" selectedImage:@"tabbar_message_center_selected"];
LFDiscoverTableViewController *message=[[LFDiscoverTableViewController alloc]init];
[self addChildVC:message Title:@"发现" image:@"tabbar_discover" selectedImage:@"tabbar_discover_selected"];
LFProfileTableViewController *profile=[[LFProfileTableViewController alloc]init];
[self addChildVC:profile Title:@"我" image:@"tabbar_profile" selectedImage:@"tabbar_profile_selected"];
}
- (void)addChildVC:(UIViewController *)childVC Title:(NSString *)title image:(NSString *)image selectedImage:(NSString *)selectedImage
{
childVC.title=title;
childVC.tabBarItem.image=[UIImage imageNamed:image];
childVC.tabBarItem.selectedImage=[[UIImage imageNamed:selectedImage]imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
//设置文字的样式
NSMutableDictionary *textAttrs=[NSMutableDictionary dictionary];
textAttrs[NSForegroundColorAttributeName]=LFColor(123, 123, 123);
[childVC.tabBarItem setTitleTextAttributes:textAttrs forState:UIControlStateNormal];
NSMutableDictionary *selectTextAttrs=[NSMutableDictionary dictionary];
selectTextAttrs[NSForegroundColorAttributeName]=[UIColor orangeColor];
[childVC.tabBarItem setTitleTextAttributes:selectTextAttrs forState:UIControlStateSelected];
childVC.view.backgroundColor=LFRandomColor;
UINavigationController *nav=[[UINavigationController alloc]initWithRootViewController:childVC];
[self addChildViewController:nav];
}
在AppDelegate.m文件中添加
self.window.rootViewController=[[LFTabbarViewController alloc]init];就行了
运行效果截图：
