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];
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?
?? ??? ?-?(id)initWithNibName:(NSString?*)nibNameOrNil?bundle:(NSBundle?*)nibBundleOrNil?{?? ?????self?=?[super?initWithNibName:nibNameOrNil?bundle:nibBundleOrNil];?? ?????if ??????????? ?????????self.hidesBottomBarWhenPushed?=?YES;?? ?????}?? ?????return ?}??
// 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 BOOL ?{?? ?????if ?????{?? ?????????return ?????}?? ?????UIView?*contentView;?? ?????? ?????if class ?????{?? ?????????contentView?=?[self.tabBarController.view.subviews?objectAtIndex:1];?? ?????}?? ?????else ?????{?? ?????????contentView?=?[self.tabBarController.view.subviews?objectAtIndex:0];?? ?????}?? ??????? ?????if ?????{?? ?????????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;?? ??????? ?}??
- (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 BOOL ?????[self?setFullScreen:YES];?? ?}?? ??? ?-?(void BOOL ?????[self?setFullScreen:NO];?? ?}?? ??? ?-?(void BOOL ??????? ?????[UIApplication?sharedApplication].statusBarHidden?=?fullScreen;?? ??????? ?????[self.navigationController?setNavigationBarHidden:fullScreen];?? ??????? ?}??
- (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。}
