Iphone 为什么不是'；t我的UIView在我的UIViewController内正确调整大小'；s子视图？

我有一个UIViewController，它包含一个子视图和一个UIToolbar。我正在尝试添加另一个UIViewController，其中包含一个MKMapView作为子视图，但它没有正确调整大小，因此，贴图与工具栏重叠。我做错了什么

- (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]; } -（id）initWithNibName:（NSString*）nibNameOrNil bundle:（NSBundle*）nibBundleOrNil{ [调试记录器写入日志：@“正在初始化RootViewController”]； if（self=[super initWithNibName:nibNameOrNil bundle:nibBundleOrNil]）{ //自定义初始化 self.title=@“根视图”； switchableView.autoresizesSubviews=是； switchableView.autoresizingMask=UIViewAutoResizingFlexibleLeLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleTopMargin； switchableView.userInteractionEnabled=是； } 回归自我； } -（无效）viewDidLoad{ [调试记录器写入日志：@“在RootViewController中调用viewDidLoad”]； [超级视图下载]； self.mapView=[[MapViewController alloc]initWithNibName:@“mapView”捆绑包：nil]自动释放]； [self.mapView.view setFrame:switchableView.frame]； [switchableView添加子视图：self.mapView.view]； } 与此相反：

switchableView.autoresizingMask=uiviewautoresizingflexibleleleftmargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleTopMargin | uiviewautoresizingflexiblebtommargin

试试这个：

switchableView.autoresizingMask=uiviewsautoresizingflexiblewidth | uiviewsautoresizingflexiblewhight

另外，尝试将mapView.view的autoresizingMask设置为相同的值
