UITabBarController

UITabBarController和UINavigationController类似,UITabBarController也可以轻松地管理多个控制器,轻松完成控制器之间的切换

1、        
创建UITabBarController对象

UITabBarController *tabbar = [[UITabBarController alloc]init];

2、        
创建相应的子控制器

ViewController *vc = [[ViewController alloc] init];

vc.tabBarItem.title = @"主页";//设置标题

vc.tabBarItem.image = [UIImage imageNamed:@"1"];//设置图片

FirstViewController *first = [[FirstViewController alloc] init];

first.tabBarItem.title = @"消息";

first.tabBarItem.image = [UIImage imageNamed:@"2"];

3、        
把子视图控制器加入UITabbarController

tabbar.viewControllers = @[vc,first];

4、        
设置window的rootViewController为UITabbarController

self.window.rootViewController = tabbar

5、        
设置tabbarVC选中第几个子视图：

[self.tabBarController setSelectedIndex:2];

6、        
跳到某个指定的VC

UIViewController *vc = [self.tabBarController.viewControllers objectAtIndex:1];

[self.tabBarController setSelectedViewController:vc];

7、        
获取当前选中的下标：

NSInteger index= self.tabBarController.selectedIndex;

8、        
标签栏信息提示：

first.tabBarItem.badgeValue = @"3";

9、        
设置选中的颜色（图片、文字）

tabbar.tabBar.tintColor = [UIColor greenColor];

10、    
设置背景图：

tabbar.tabBar.backgroundImage = [UIImage imageNamed:@"buy_ex"];

11、    
设置背景色

tabbar.tabBar.barTintColor = [UIColor brownColor];

12、  
置选中、未选中的图片

UIIm设age *image=[[UIImage imageNamed:@"3"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

UIImage *image2 =[[UIImage imageNamed:@"tabbar_profile_selected"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];

second.tabBarItem = [[UITabBarItem alloc]initWithTitle:@"个人" image:image selectedImage:image2];
