Iphone 使用NSMutableArray更改子视图

我已经创建了一个包含三个ViewController的数组，我想在它们之间滑动。并在屏幕上设置动画

到目前为止，我已经创建了视图数组，具有手势控制，并且正在将数组的第一个视图加载到保存动画内容的viewController的viewDidLoad方法中的视图中

我所做的是添加到viewController对象（当前、furutre），当应用程序首次加载时，我将阵列的第一个视图放入当前viewController。。然后，当我滑动视图时，我将阵列中的下一个视图加载到未来的viewcontroller中，并执行动画。。然后我对第三个动画也做了同样的操作。。但是它崩溃了，因为在最后一个动画之前，我没有将第二个视图传递给当前，然后将第三个视图传递给未来。。（希望这有意义。）

这是我目前正在做的事情的代码

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.

    self.title = @"Prototype";
    //Initalizse the swipe gestuer listener
    [self setupLeftSwipeGestureRecognizer];
    [self setupRightSwipeGestureRecognizer];

    //Initalize all of the swipe views
    DetailViewController *DVCA = [[DetailViewController alloc] initWithNibName:@"DetailViewController" bundle:[NSBundle mainBundle]];
    DetailViewControllerB *DVCB = [[DetailViewControllerB alloc] initWithNibName:@"DetailViewControllerB" bundle:[NSBundle mainBundle]];
    DetailViewControllerC *DVCC = [[DetailViewControllerC alloc] initWithNibName:@"DetailViewControllerC" bundle:[NSBundle mainBundle]];

    //Assinge swipeviews to viewArray
    viewArray = [NSArray arrayWithObjects:DVCA, DVCB, DVCC, nil];

    //Initalize viewcount so it can keep track of which viewController is in view
    viewCount = 0;

    // set detail View as first view 
    currentViewController = [viewArray objectAtIndex:viewCount];
    [self.view addSubview:currentViewController.view];

}


// Need to change this to work with viewArray
- (void)swipedScreen:(UISwipeGestureRecognizer*)gesture {

    //Left swipe
    if (gesture.direction == UISwipeGestureRecognizerDirectionLeft) {

        //stops swipes from returning any viewCount outside of viewArrays range
        if ((viewCount >= 0) || (viewCount >= 2)) {
            //Increment for next view
            viewCount += 1;

            futureViewController = [viewArray objectAtIndex:viewCount];
            [self.view addSubview:futureViewController.view];
            [futureViewController.view setFrame:CGRectMake(320, 0, self.view.frame.size.width, self.view.frame.size.height)];

            [UIView animateWithDuration:0.25 animations:^{
                [futureViewController.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
                [currentViewController.view setFrame:CGRectMake(-320, 0, self.view.frame.size.width, self.view.frame.size.height)];
            }];

        }

    }
    //Right swipe -- still need to do this (go back through the view array.
    else if (gesture.direction == UISwipeGestureRecognizerDirectionRight){

        [UIView animateWithDuration:0.25 animations:^{
            [self.detailViewA.view setFrame:CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height)];
            [self.detailViewB.view setFrame:CGRectMake(320, 0, self.view.frame.size.width, self.view.frame.size.height)];
        }];

    }
}

很抱歉，您应该使用UInavigationController在视图控制器的视图之间切换。 您仍然可以设置帧的动画，而不使用uinavigation Controller中包含的经典动画。

您可以在导航控制器中按下并弹出视图控制器。在apple文档中查找UINavigationController，如果您的代码试图避免出现这种情况，您不需要在顶部设置导航栏。

您使用过UIScrollView吗？我个人觉得UIScrollView的效果比滑动手势更好。我需要每个视图的ViewController，因为我在每个视图中都做了一些其他事情（web请求等），我想用ViewController控制这些事情。。。你认为这是个好主意吗？是的，我想在这里做的特别的事情是在导航控制器内的视图中。。。很难解释，但基本上我在NavigationStack中有几个视图，然后最终视图需要显示比一个视图可以处理的信息多得多的信息，我是否要有一个可滑动的界面，用户可以来回滑动，以显示我试图创建的一组视图中的所有相关信息。您可以在导航控制器中设置导航控制器
