早上好,我正试图隐藏一个UITabBarItem,在这里看了很多帖子后,我疯了......我可以正确地获得tabItem,但它并没有隐藏。我在Storyboard中设置了TabBar。
这是我的代码..我尝试过的3个选项中没有一个...
任何帮助将不胜感激
@implementation unidaAppDelegate
@synthesize window = _window;
@synthesize tabBarController = _tabBarController;
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
UIStoryboard *storyboard = [UIStoryboard storyboardWithName:@"MainStoryboard" bundle:nil];
self.tabBarController = [storyboard instantiateViewControllerWithIdentifier:@"myTab"];
NSMutableArray *tabs = [NSMutableArray arrayWithArray:self.tabBarController.viewControllers];
NSLog(@"Array:%@",tabs);
/*
OPTION 1
NSMutableArray *viewControllersCopy = [[self.tabBarController viewControllers] mutableCopy];
[viewControllersCopy removeObjectAtIndex:2];
NSArray *modifiedViewControllers = [[NSArray alloc] initWithArray:viewControllersCopy];
[self.tabBarController setViewControllers:modifiedViewControllers animated:NO];
OPTION 2
NSMutableArray *modifyMe = [[self.tabBarController.tabBar items] mutableCopy];
[modifyMe removeObjectAtIndex:2];
NSArray *newItems = [[NSArray alloc] initWithArray:modifyMe];
[self.tabBarController.tabBar setItems:newItems animated:true];
OPTION 3
NSLog(@"TabBarItem: %@",[[self.tabBarController.tabBar.items objectAtIndex:2] title]);
[[self.tabBarController.tabBar.items objectAtIndex:2] setEnabled:FALSE];
*/
sleep(1);
return YES;
}
答案 0 :(得分:0)
如果您正在使用xcode 4.x尝试通过选择要嵌入tabBarController的UIview并转到编辑器>嵌入>来尝试这样做。标签栏控制器。我这样做,效果更好。
