爲什麼我的UIView在我的UIViewController的子視圖中沒有正確調整大小？

Question

我有一個包含子視圖和UIToolbar的UIViewController。我試圖添加另一個包含MKMapView作爲子視圖的UIViewController，但它沒有正確調整大小，因此地圖與工具欄重疊。我究竟做錯了什麼？

 
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil { 
    [DebugLogger writeLog:@"Initializing RootViewController"]; 
    if (self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]) { 
     // Custom initialization 
     self.title = @"Root View"; 

     switchableView.autoresizesSubviews = YES; 
     switchableView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin; 
     switchableView.userInteractionEnabled = YES; 

    } 
    return self; 
} 

- (void)viewDidLoad { 
    [DebugLogger writeLog:@"Calling viewDidLoad in RootViewController"]; 
    [super viewDidLoad]; 

    self.mapView = [[[MapViewController alloc] initWithNibName:@"MapView" bundle:nil] autorelease]; 

    [self.mapView.view setFrame:switchableView.frame]; 

    [switchableView addSubview:self.mapView.view]; 
}

取而代之的是：

switchableView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleBottomMargin;

試試這個：

switchableView.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight;

另外，儘量mapView.view的autoresizingMask設置爲相同的事情。
