早上好,我試圖隱藏一個UITabBarItem,在閱讀了很多帖子後,我越來越瘋狂....我可以正確地獲取tabItem,但它不會隱藏。我在故事板中設置我的TabBar。UITabBarItem顯示/隱藏
這裏是我的3個選項我試過作品code..none ...
任何幫助會,如果你正在使用的Xcode 4.x的理解
@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;
}
感謝ClOck,這是我做到的方式,但UITabBarItem抵制隱藏.... – Christian 2012-03-19 07:13:10
