狀態條StatusBar

[cpp] view plaincopyprint?

[UIApplication?sharedApplication].statusBarHidden?=?YES;??

[UIApplication sharedApplication].statusBarHidden = YES;

?導航條NavigationBar

[cpp] view plaincopyprint?

[self.navigationController?setNavigationBarHidden:YES];??

[self.navigationController setNavigationBarHidden:YES];

TabBar

方法1

[cpp] view plaincopyprint?

[self.tabBarController.tabBar?setHidden:YES];??

[self.tabBarController.tabBar setHidden:YES];

這個方法有問題，雖然tabBar被隱藏了，但是那片區域變成了一片空白，無法被其他視圖使用。

方法2

對于navigationController+tabBarController的結構，可以在push下一級的childController之前將childController的hidesBottomBarWhenPushed屬性設為YES。

比如，可以在childController的初始化方法中做這件事，代碼如下：

[cpp] view plaincopyprint?

//?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;??

?}??

// 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

[cpp] view plaincopyprint?

-?(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];?????

?}??

- (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]; }

時機

[cpp] view plaincopyprint?

-?(void)viewWillAppear:(BOOL)animated?{??

?????[self?setFullScreen:YES];??

?}??

???

?-?(void)viewWillDisappear:(BOOL)animated?{??

?????[self?setFullScreen:NO];??

?}??

???

?-?(void)setFullScreen:(BOOL)fullScreen?{??

?????//?狀態條 ??

?????[UIApplication?sharedApplication].statusBarHidden?=?fullScreen;??

?????//?導航條 ??

?????[self.navigationController?setNavigationBarHidden:fullScreen];??

?????//?tabBar的隱藏通過在初始化方法中設置hidesBottomBarWhenPushed屬性來實現。??

?}??

- (void)viewWillAppear:(BOOL)animated {[self setFullScreen:YES];}- (void)viewWillDisappear:(BOOL)animated {[self setFullScreen:NO];}- (void)setFullScreen:(BOOL)fullScreen {// 狀態條[UIApplication sharedApplication].statusBarHidden = fullScreen;// 導航條[self.navigationController setNavigationBarHidden:fullScreen];// tabBar的隱藏通過在初始化方法中設置hidesBottomBarWhenPushed屬性來實現。}
