效果图如下
核心代码
/**
* 添加子控制器，我这里值添加了4个，没有占位自控制器
*/
- (void)setUpChildViewController{
[self addOneChildViewController:[[UINavigationController alloc]initWithRootViewController:[[DWHomeViewController alloc]init]]
WithTitle:@"首页"
imageName:@"home_normal"
selectedImageName:@"home_highlight"];
[self addOneChildViewController:[[UINavigationController alloc]initWithRootViewController:[[DWSameFityViewController alloc] init]]
WithTitle:@"同城"
imageName:@"mycity_normal"
selectedImageName:@"mycity_highlight"];
[self addOneChildViewController:[[UINavigationController alloc]initWithRootViewController:[[DWMessageViewController alloc]init]]
WithTitle:@"消息"
imageName:@"message_normal"
selectedImageName:@"message_highlight"];
[self addOneChildViewController:[[UINavigationController alloc]initWithRootViewController:[[DWMineViewController alloc]init]]
WithTitle:@"我的"
imageName:@"account_normal"
selectedImageName:@"account_highlight"];
}
/**
* 添加一个子控制器
*
* @param viewController 控制器
* @param title 标题
* @param imageName 图片
* @param selectedImageName 选中图片
*/
- (void)addOneChildViewController:(UIViewController *)viewController WithTitle:(NSString *)title imageName:(NSString *)imageName selectedImageName:(NSString *)selectedImageName{
viewController.view.backgroundColor = DWRandomColor;
viewController.tabBarItem.title = title;
viewController.tabBarItem.image = [UIImage imageNamed:imageName];
UIImage *image = [UIImage imageNamed:selectedImageName];
image = [image imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal];
viewController.tabBarItem.selectedImage = image;
[self addChildViewController:viewController];
}
只加了4个控制器，但是有5个按钮。 基于系统自带，重新布局，没有完全自定义
