SKScene alloc出错

Question

在SKScene gamescene中，我分配了场景，但它有No visible @interface with 'SKScene' declares the selector alloc.的错误消息

我认为这意味着我不能在我的界面中声明它？更正plz。

     -(void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
UITouch *touch = [touches anyObject];
CGPoint location = [touch locationInNode:self];
SKNode *node = [self nodeAtPoint:location];

// if play button touched, start transition to next scene
if ([node.name isEqualToString:@"play"]) {
    NSLog(@"play pressed");
    SKScene *GameScene = [[GameScene alloc] initWithSize:self.size];
    SKTransition *flip = [SKTransition flipVerticalWithDuration:1.0];
    [self.view presentScene:GameScene transition:flip];
   }
}

看起来您正在尝试创建一个与该类同名的变量！

SKScene *GameScene = [[GameScene alloc] initWithSize:self.size];

这可能会让编译器感到困惑。将* GameScene的变量名称更改为其他名称，看看是否有效。
