[英]IOS: How to change the position of UITabbar to the top of view
我在我的項目中使用UITAbBar
,我想將其位置從底部更改為頂部。 我必須為此輸入什么代碼。
{
[super viewDidLoad];
// Do any additional setup after loading the view.
self.view.backgroundColor = [UIColor whiteColor];
self.title = @"Welcome";
_friendviewcontroller = [FriendsViewController new];
_homeviewcontroller = [HomePageViewController new];
_notifviewcontroller = [NotificationViewController new];
_messageviewcontroller = [MessagesViewController new];
self.tabbarcontroller = [[UITabBarController alloc]init];
self.viewControllers = [NSArray arrayWithObjects:_homeviewcontroller,_messageviewcontroller,_friendviewcontroller,_notifviewcontroller, nil];
//UITabBar *tabBar = self.tabBarController.tabBar;
UITabBarItem *item0 = [self.tabBar.items objectAtIndex:0];
UITabBarItem *item1 = [self.tabBar.items objectAtIndex:1];
UITabBarItem *item2 = [self.tabBar.items objectAtIndex:2];
UITabBarItem *item3 = [self.tabBar.items objectAtIndex:3];
}
UITabBarController *tabBarController;
tabBarController = [[UITabBarController alloc]init];
// define a custom frame size for the entire tab bar controller that will be in the
// top of the screen.
CGRect tabBarFrame;
tabBarFrame = CGRectMake(0, 0, 320, 200);
tabBarController.view.frame = tabBarFrame;
使用UITabBarController是不可能的。 它總是停留在底部。
