Ios 使用UIKit'；s带SpriteKit的UIScrollView

我在这里读到两个关于这个的问题，都有相同的答案。建议的解决方案是创建UIScrollView对象，然后将其添加到目标场景的didMoveToView:中SKScene的父视图中，并在willMoveFromView:中将其删除

这就是我实现的目标场景代码：

@interface MQSSMakerScene ()

@property BOOL contentCreated;
@property MQSSMakerWorkspaceLayer *workspaceLayer;
@property MQSSMakerDockLayer *dockLayer;
@property UIScrollView *scrollView;

@end


@implementation MQSSMakerScene

- (id)initWithSize:(CGSize)size
{
    if (self = [super initWithSize:size]) {
        CGSize layerSize        = CGSizeMake(944, 140);
        CGPoint layerPosition   = CGPointMake(40, 768-(140+30));
        CGRect viewFrame = CGRectMake(layerPosition.x, layerPosition.y, layerSize.width, layerSize.height);
        _scrollView = [[UIScrollView alloc] initWithFrame:viewFrame];
        _scrollView.contentSize                     = CGSizeMake(2000, 120);
        _scrollView.scrollEnabled                   = YES;
        _scrollView.showsHorizontalScrollIndicator  = YES;
        _scrollView.backgroundColor                 = [UIColor brownColor];
    }

    return self;
}

- (void)didMoveToView:(SKView *)view
{
    [super didMoveToView:view];

    if(!self.contentCreated) {
        [self createSceneContents];
        self.contentCreated = YES;
    }

    [self.view addSubview:_scrollView]; // --> WHERE IT'S BEING ADDED
}

- (void)willMoveFromView:(SKView *)view
{
    [super willMoveFromView:view];

    [_scrollView removeFromSuperview]; // --> WHERE IT'S BEING REMOVED
}

- (void)createSceneContents
{
    self.backgroundColor = [UIColor colorWithHue:.237 saturation:.56 brightness:.46 alpha:1];
    self.scaleMode = SKSceneScaleModeAspectFill;

    [self addChild:[self newMakerLayout]];
}

- (SKNode *)newMakerLayout
{
    SKNode *mainLayout  = [[SKNode alloc] init];
    self.workspaceLayer = [[MQSSMakerWorkspaceLayer alloc] init];
    self.dockLayer      = [[MQSSMakerDockLayer alloc] init];

    [mainLayout addChild:self.workspaceLayer];
    [mainLayout addChild:self.dockLayer];

    MQSSStoryObject *ob1 = [[MQSSStoryObject alloc] initWithImageNamed:@"maker-1.png"];
    [self.workspaceLayer addChild:ob1];

    return mainLayout;
}

@end

请注意，单击按钮时，用户应从主场景转到此场景。现在的问题是，一旦我添加了行：

[self.view addSubview:_scrollView];

要将UIScrollView对象添加到此场景，应用程序将不再转到此场景，而是将UIScrollView添加到我要从中转换的主场景。在过渡到另一个场景时，它也不会将其删除。一旦我注释掉这一行，一切都会像预期的那样工作，显然没有呈现UIScrollView

我被卡住了。非常感谢您的任何帮助或建议。谢谢

我终于明白了我的问题所在。我使用viewController的-（void）willLayoutSubviews方法来确保有正确的边界，但是我忘记了查看是否已经显示了我的场景。这导致每次在旧场景的上方布置视图时，都会出现一个新的Welcome场景

-(void)willLayoutSubviews
{
    if(!self.didPresentScene)
    {
        // Present scene here
        ....
        self.didPresentScene = YES;
    }
}

这正是我所面临的问题，只有在UITextView中。这真是令人发狂。。。似乎也无法让我的google foo帮助我。你找到解决办法了吗？你真是个英雄！一个月了，我还没弄明白，现在就行了！谢谢，非常欢迎！我很高兴帮助了别人：）编码快乐！
