添加TabBarController作为视图的子视图

Question

我在加载启动屏幕时启动应用程序。然后我想加载一个TabBarController，它是ViewControllers。但是，我的TabBarController窗口不会缩放到屏幕大小。

底部可能有3/4的TabBar被切断，状态栏下方的屏幕顶部会出现一个细长的APROX 20像素间隙。如何正确调整TabBarController的大小？

这里是我的SplashViewController加载飞溅视图的代码，以及TabBarController：

-(void)loadView{ 
// Init the view 
CGRect appFrame = [[UIScreen mainScreen] applicationFrame]; 
UIView *view = [[UIView alloc] initWithFrame:appFrame]; 
view.autoresizingMask = UIViewAutoresizingFlexibleHeight|UIViewAutoresizingFlexibleWidth; 
self.view = view; 
[view release]; 

splashImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"Splash.png"]]; 
splashImageView.frame = CGRectMake(0,0,320,458); 
[self.view addSubview:splashImageView]; 

viewController = [[FlashCardViewController alloc] initWithNibName:@"FlashCardViewController" bundle:[NSBundle mainBundle]]; 
//viewController.view.bounds = [[UIScreen mainScreen]bounds]; 
viewController.title = @"Quiz"; 
viewController.tabBarItem.image = [UIImage imageNamed:@"puzzle.png"]; 

UIViewController *viewController2 = [[UIViewController alloc] initWithNibName:nil bundle:nil]; 
viewController2.title = @"Nada"; 
viewController2.tabBarItem.image = [UIImage imageNamed:@"magnifying-glass.png"]; 
//viewController.view.alpha = 0.0; 
//[self.view addSubview:viewController.view]; 

tabBarController = [[UITabBarController alloc] init]; 
tabBarController.viewControllers = [NSArray arrayWithObjects:viewController, viewController2, nil]; 
[viewController2 release]; 
tabBarController.view.alpha = 0.0; 
//tabBarController.tabBarItem.image = [UIImage imageNamed:@"State_California.png"]; 
//tabBarController.tabBarItem.title = @"State_California.png"; 
tabBarController.view.bounds = [[self view] bounds]; 
//tabBarController.view.frame = [[UIScreen mainScreen] applicationFrame]; 
[self.view addSubview:tabBarController.view]; 

timer = [NSTimer scheduledTimerWithTimeInterval:2.0 target:self selector:@selector(fadeScreen) userInfo:nil repeats:NO]; 
} 
-(void) fadeScreen 
{ 
[UIView beginAnimations:nil context:nil]; // begin animation block 
[UIView setAnimationDuration:0.75]; // sets animation duration 
[UIView setAnimationDelegate:self]; // sets the delegate for this block 
[UIView setAnimationDidStopSelector:@selector(finishedFading)]; // Calls finishFading 
self.view.alpha = 0.0; // // Fades the alpha to 0 over animation 
[UIView commitAnimations]; // Commits this block, done 
} 

-(void) finishedFading 
{ 
[UIView beginAnimations:nil context:nil]; // Begin animation block 
[UIView setAnimationDuration:0.75]; // set duration 
self.view.alpha = 1.0; // fades the view to 1.0 alpha over .75 seconds 
//viewController.view.alpha = 1.0; 
tabBarController.view.alpha = 1.0; 
[UIView commitAnimations]; 
[splashImageView removeFromSuperview]; 
} 

Answer 1

我终于找到成才工程。相反的：

tabBarController.view.frame = [[UIScreen mainScreen] applicationFrame]; 

或

tabBarController.view.bounds = [[self view] bounds]; 

因为我无法找到和这种尺寸的自动或命名设置，我不得不创建我自己的矩形显示在屏幕减去状态栏的大小。

tabBarController.view.frame = CGRectMake(0,0,320,460);

我刚刚完成了几乎相同的工作，遇到了同样的问题，但最终我找到了工作。

1. 在Xcode中创建一个视图控制器类叫做Test1ViewController并添加以下内容：

   @interface Test1ViewController : UIViewController { 
       IBOutlet UITabBarController *tbc; 
   } 
   
   @property (nonatomic,retain) IBOutlet UITabBarController *tbc; 
   @end 
   

2. 创建视图XIB称为Test1View

3. 添加TabBarViewController到厦门国际银行

4. 将XIB中的文件所有者设置为Test1ViewController。

5. 将文件所有者中的tbc IBOutlet连接到XIB中的选项卡栏控制器。

6. 将文件所有者中的view IBOutlet连接到XIB中的视图。

7. 在你SplashViewController.h添加属性

   Test1ViewController *tabBarViewController; 
   

8. 合成下你SplashViewController.m的tabBarViewController。

9. 用以下替换您TabBarController创建代码在你loadView方法SplashViewController：

   tabBarViewController = [[Test1ViewController alloc] initWithNibName: 
        @"Test1View" bundle:[NSBundle mainBundle]]; 
   tabBarViewController.view.alpha = 0.0; 
   [self.view addSubview:[tabBarViewController view]]; 
   

10. 下面是失踪了我一下。在Test1ViewController.m，你需要添加下面一行到viewDidLoad方法：

    self.view = tbc.view; 
    

11. 最后，我也不得不改变SplashViewController.m的finishedFading方法来设置透明度为1.0的tabBarViewController视图。

    -(void) finishedFading 
    { 
        [UIView beginAnimations:nil context:nil]; 
        [UIView setAnimationDuration:0.75]; 
        self.view.alpha = 1.0; 
        tabBarViewController.view.alpha = 1.0; 
        [UIView commitAnimations]; 
        [splashImageView removeFromSuperview]; 
    } 
    

我希望这有助于。
