Answer 1

第一個選項卡上，添加任何檢查你需要爲他們是否被登錄，如果沒有，目前與登錄域模態的視圖。

//some test here to determine state of self.registered 
if(self.registered==FALSE){ 
      LoginViewController *login = [[LoginViewController alloc] initWithNibName: @"loginView" bundle: nil]; 
      login.modalTransitionStyle = UIModalTransitionStyleCrossDissolve; 
      [self.navigationController presentModalViewController:login animated:YES]; 
      [login release]; 
     }

有了這個，你可以隱藏，以及如何的UITabBarController -

- (void) hideTabBar:(UITabBarController *) tabbarcontroller { 


    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:0.5]; 
    for(UIView *view in tabbarcontroller.view.subviews) 
    { 
     if([view isKindOfClass:[UITabBar class]]) 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, 480, view.frame.size.width, view.frame.size.height)]; 
     } 
     else 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 480)]; 
     } 

    } 

    [UIView commitAnimations]; 





} 

- (void) showTabBar:(UITabBarController *) tabbarcontroller { 

    [UIView beginAnimations:nil context:NULL]; 
    [UIView setAnimationDuration:0.5]; 
    for(UIView *view in tabbarcontroller.view.subviews) 
    { 
     NSLog(@"%@", view); 

     if([view isKindOfClass:[UITabBar class]]) 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, 431, view.frame.size.width, view.frame.size.height)]; 

     } 
     else 
     { 
      [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, 431)]; 
     } 


    } 

    [UIView commitAnimations]; 
}

你可以這樣做：

在delegate.h聲明你的觀點，

UIView *indicatorView; 
UIImageView *splashV; 

現在在delegate.m

- (void)applicationDidFinishLaunching:(UIApplication *)application 
{ 
     indicatorView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 320, 480)]; 
    splashV=[[UIImageView alloc]initWithFrame:CGRectMake(0, 20, 320, 460)]; 
    [splashV setImage:[UIImage imageNamed:@"Default.png"]]; 
    [indicatorView setBackgroundColor:[UIColor clearColor]]; 

     [indicatorView addSubview:splashV]; 
    [self.window addSubview:indicatorView]; 

} 

& 上成功登錄

-(void)SuccessfulLoginDone 
{ 
    [window addSubview:[tabBarController view]]; 

    [window makeKeyAndVisible]; 

} 

希望這將是更好的做這個任務。
