[英]Title of tab bar items not showing
![I am creating a tab bar controller programmatically: ![我正在以编程方式创建标签栏控制器:
tabBarController = [[UITabBarController alloc] init];
FirstViewController* vc1 = [[FirstViewController alloc] init];
SecondViewController* vc2 = [[SecondViewController alloc] init];
vc1.title = @"Dallas";//[[NSUserDefaults standardUserDefaults] objectForKey:@"Citynamefrmhome"];
vc1.tabBarItem.image = [UIImage imageNamed:@"Dealss.png"];
vc2.title = @"My Vouchers";
vc2.tabBarItem.image = [UIImage imageNamed:@"nav_voucher_S.png"];
NSArray* controllers = [NSArray arrayWithObjects:vc1,vc2, nil];
tabBarController.viewControllers = controllers;
[self.view addSubview:tabBarController.view];
[vc1 release];
[vc2 release];
if I load it when the app starts, it looks great (look at figure 1): 如果我在应用启动时加载它,它看起来很棒(请参见图1):
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
autoMagically = [[AutoMagically alloc] initWithNibName:nil bundle:nil];
//self.window.rootViewController = self.dummyView;
[self.window addSubview:autoMagically.view];
[self.window makeKeyAndVisible];
return YES;
}
if I load it when a button is clicked, the way i wanna do it, it looks like figure 2. See how the titles arent showing and the buttons seem to be getting cutoff: 如果在单击按钮时加载它,我的方式就如图2所示。请参见标题显示的内容和按钮的显示方式:
- (void)LoadView
{
AutoMagically *autoMagic = [[AutoMagically alloc]
initWithNibName:nil bundle:nil];
self.autoMagically = autoMagic;
[self.view insertSubview:autoMagic.view atIndex:0];
[autoMagic release];
}
Does anyone know why this is behaving like this?] 1 有谁知道为什么这样表现?] 1
You can call 你可以打电话
[[[self.parentViewController.tabBarController.tabBar.items objectAtIndex:/*a number based on what tab it was ex: 2*/]setTitle:@"string"];
in your -viewDidLoad
or -awakeFromNib
methods. 在
-viewDidLoad
或-awakeFromNib
方法中。 It might be better to use the latter instead of the former. 最好使用后者而不是前者。
