[iOS功能]- iOS 宏定义状态栏、导航栏、tabBar高

//获取状态栏的高度
CGFloat statusHeight = [[UIApplication sharedApplication] statusBarFrame].size.height;
NSLog(@"状态栏高度：%f",statusHeight);

//获取导航栏的高度
CGFloat navHeight = self.navigationController.navigationBar.frame.size.height;
NSLog(@"导航栏高度：%f",navHeight);

//获取tabBar的高度
//1.在tabBarController中使用（你的继承自UITabBarController的VC）
CGFloat tabBarHeight = self.tabBar.frame.size.height;
NSLog(@"tabBar高度：%f",tabBarHeight);
//2.在非tabBarController中使用
UITabBarController *tabBarVC = [[UITabBarController alloc] init];//(这儿取你当前tabBarVC的实例)
CGFloat tabBarHeight = tabBarVC.tabBar.frame.size.height;
NSLog(@"tabBar高度：%f",tabBarHeight);
