Question

我的应用中有一个按钮可以切换容器视图，从tableview到Google地图视图。

交换机工作大约4次，然后当我再次尝试切换容器视图时，应用程序崩溃，我收到以下错误：

(71189,0xac12f2c0) malloc: *** mmap(size=1492946944) failed (error code=12)

以下是切换容器的代码。对于凌乱的代码感到抱歉，但viewcontroller2实际上是一个tableview，只是错误地命名。 det是BOOL

-(IBAction)changer:(id)sender
{

    if(det == TRUE)
    {
        test *viewController2 = [[test alloc]init];
        viewController2.view.frame = self.container.bounds;

        [viewController2 willMoveToParentViewController:self];
        [self.container addSubview:viewController2.view];
        [self addChildViewController:viewController2];
        [viewController2 didMoveToParentViewController:self];

        [UIView beginAnimations:nil context:nil];

        [UIView setAnimationDuration:1];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromLeft  forView:self.container cache:YES];

        [UIView commitAnimations];

        det = FALSE;
    }
    else
    {
        ViewController *viewController1 = [self.storyboard instantiateViewControllerWithIdentifier:@"vc1"];
        viewController1.view.frame = self.container.bounds;

        [viewController1 willMoveToParentViewController:self];
        [self.container addSubview:viewController1.view];
        [self addChildViewController:viewController1];
        [viewController1 didMoveToParentViewController:self];
        [UIView beginAnimations:nil context:nil];

        [UIView setAnimationDuration:1];

        [UIView setAnimationTransition:UIViewAnimationTransitionFlipFromRight  forView:self.container cache:YES];

        [UIView commitAnimations];

        det = TRUE;

    }
}

知道发生了什么事吗？
