ios - SKScene 分配错误

Question

在 SKScene 游戏场景中，我分配了场景，但它有一条错误消息No visible @interface with 'SKScene' declares the selector alloc.

我认为这意味着我没有在我的界面中声明它？？更正请。

     -(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类同名的变量！

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

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