状态条StatusBar [UIApplication sharedApplication].statusBarHidden = YES;

 导航条NavigationBar

[self.navigationController setNavigationBarHidden:YES];


TabBar

方法1

[self.tabBarController.tabBar setHidden:YES];


这个方法有问题，虽然tabBar被隐藏了，但是那片区域变成了一片空白，无法被其他视图使用。

方法2

对于navigationController+tabBarController的结构，可以在push下一级的childController之前将childController的hidesBottomBarWhenPushed属性设为YES。

比如，可以在childController的初始化方法中做这件事，代码如下：

// The designated initializer. Override if you create the controller programmatically and want to perform customization that is not appropriate for viewDidLoad. - (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]; if (self) { // Custom initialization. self.hidesBottomBarWhenPushed = YES; } return self; }

方法3

- (void)makeTabBarHidden:(BOOL)hide { if ( [self.tabBarController.view.subviews count] < 2 ) { return; } UIView *contentView; if ( [[self.tabBarController.view.subviews objectAtIndex:0] isKindOfClass:[UITabBar class]] ) { contentView = [self.tabBarController.view.subviews objectAtIndex:1]; } else { contentView = [self.tabBarController.view.subviews objectAtIndex:0]; } // [UIView beginAnimations:@"TabbarHide" context:nil]; if ( hide ) { contentView.frame = self.tabBarController.view.bounds; } else { contentView.frame = CGRectMake(self.tabBarController.view.bounds.origin.x, self.tabBarController.view.bounds.origin.y, self.tabBarController.view.bounds.size.width, self.tabBarController.view.bounds.size.height - self.tabBarController.tabBar.frame.size.height); } self.tabBarController.tabBar.hidden = hide; // [UIView commitAnimations]; }



时机

- (void)viewWillAppear:(BOOL)animated { [self setFullScreen:YES]; } - (void)viewWillDisappear:(BOOL)animated { [self setFullScreen:NO]; } - (void)setFullScreen:(BOOL)fullScreen { // 状态条 [UIApplication sharedApplication].statusBarHidden = fullScreen; // 导航条 [self.navigationController setNavigationBarHidden:fullScreen]; // tabBar的隐藏通过在初始化方法中设置hidesBottomBarWhenPushed属性来实现。 }
