当试图在模拟器中显示SKScene时，应用程序在iPhone 5s和iPad中崩溃

Question

好的所以我有一个40级别的应用程序，我有一个滚动视图，按钮每个级别有不同的标签（级别1的标签为1，级别17的标签为17，等等......）< / p>

这些级别中的每一个都有一个SKScene类（level1.h / level1.m，level35.h / level35.m，等等），我将其中的每一个都导入到我的ViewController.m中，如下所示：

#import "level1.h"
#import "level2.h"
#import "level3.h"
#import "level4.h"
#import "level5.h"
#import "level6.h"
#import "level7.h"
#import "level8.h"
#import "level9.h"
#import "level10.h"
#import "level11.h"
#import "level12.h"
#import "level13.h"

你明白了

然后我有一个动作链接到所有40个按钮（有40个标签）直到相同的功能。然后我这样做了：

注意：您可能不需要阅读超过2个案例陈述以及最终和开头...我只是想彻底并提供所有这些。

-(IBAction)levelButtonPressed:(id)sender {
    UIButton *button = (UIButton*)sender;
    NSLog(@"button tag: %li",(long)button.tag);
    // Configure the view.

    skView = (SKView *)self.view;
    SKScene *scene;

    if (button.tag > [[NSUserDefaults standardUserDefaults] integerForKey:@"currentLevel"]) {
        NSLog(@"level not available");
    } else {
        switch (button.tag) {
            case 1:
                // Create and configure the scene.
                scene = [level1 sceneWithSize:skView.bounds.size];
                scene.scaleMode = SKSceneScaleModeAspectFill;
                break;
            case 2:
                // Create and configure the scene.
                scene = [level2 sceneWithSize:skView.bounds.size];
                scene.scaleMode = SKSceneScaleModeAspectFill;
                break;
            case 3:

        scrollView.hidden = YES;
        quitButton.hidden = NO;
    }

}

所以我将代码提交给苹果，他们说它在iPad和iPhone 5s中崩溃了。我不知道该怎么做所以请帮助！我查看了所有内容，但它无法正常工作。
