navigationController使用, 通過生命周期的隐藏，還有自定義

這是最簡單的通過聲明周期，navigationBar不隐藏  tabBar隐藏 

-(void)viewWillDisappear:(BOOL)animated

{

    self.navigationController.navigationBarHidden = NO;

    self.tabBarController.tabBar.hidden=YES;

}

1 2 3 4 5 6 7 8 9 10 11 12 13

//1.設定self.tabBarController.tabBar.hidden=YES; self .tabBarController.tabBar.hidden= YES ; //2.如果在push跳轉時需要隐藏tabBar，設定self.hidesBottomBarWhenPushed=YES;這用是通過聲明周期，push故 self .hidesBottomBarWhenPushed= YES ; NextViewController *next=[[NextViewController alloc]init]; [ self .navigationController pushViewController:next animated: YES ]; self .hidesBottomBarWhenPushed= NO ; //并在push後設定self.hidesBottomBarWhenPushed=NO; //這樣back回來的時候，tabBar會恢複正常顯示。

1.隐藏特定UIViewController的導航欄,在該視圖控制器中加入代碼：

- (void) viewDidAppear:(BOOL)animated

{

    [super viewDidAppear:animated];

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

}

- (void) viewDidDisappear:(BOOL)animated

{

    [super viewDidDisappear:animated];

    [self.navigationController setNavigationBarHidden:NO animated:YES];

} 2.初始化，始終為

[[UINavigationController alloc] initWithRootViewController:[[UIViewController alloc] init]] 3.定制自己的UINavigationController，是的push和present的方式變成自己想要的方式，以便統一處理視圖特效
