顯示在下方空白處當我使用TabBarController在頂部

Question

我在底部越來越空的空間，當我在screen.In iOS7它的頂部具有的UITabBarController使用此代碼

 self.edgesForExtendedLayout=UIRectEdgeBottom; 
    self.extendedLayoutIncludesOpaqueBars = YES; 

工作

//如果在iOS 6中得到空space.Below是我用來顯示的TabBar

appDelegate.tabBarController.tabBar.frame = CGRectMake(0, 20, 320, 50); 
appDelegate.tabBarController.delegate=self; 

UIView *view=[[UIView alloc]initWithFrame:CGRectMake(0, -20, 320, 600)]; 

viewControllers = [[NSMutableArray alloc] init]; 

TagViewController *view1 = [[TagViewController alloc] init]; 
UINavigationController *nav1=[[UINavigationController alloc]initWithRootViewController:view1]; 
[viewControllers addObject:nav1]; 

ContactsViewController *view2 = [[ContactsViewController alloc] init]; 
UINavigationController *nav2=[[UINavigationController alloc]initWithRootViewController:view2]; 
[viewControllers addObject:nav2]; 

MessagesViewController *view3 = [[MessagesViewController alloc] init]; 
UINavigationController *nav3=[[UINavigationController alloc]initWithRootViewController:view3]; 
[viewControllers addObject:nav3]; 

RewardsViewController *view4 = [[RewardsViewController alloc] init]; 
UINavigationController *nav4=[[UINavigationController alloc]initWithRootViewController:view4]; 
[viewControllers addObject:nav4]; 

SettingsViewController *view5 = [[SettingsViewController alloc] init]; 
UINavigationController *nav5=[[UINavigationController alloc]initWithRootViewController:view5]; 
[viewControllers addObject:nav5]; 

[appDelegate.tabBarController setViewControllers:viewControllers]; 

appDelegate.tabBarController.tabBarController.view.frame=CGRectMake(0, 0, 320, 480); 
[view addSubview:appDelegate.tabBarController.view]; 

[self.view addSubview:view];

在viewWillAppear中試試這個代碼代碼：

self.tabBarController.tabBar.hidden = YES; 

或

[self.tabBarController.tabBar setHidden:YES];
