我发现问题很接近，但没有任何帮助，谁能明白我为什么会收到这个错误？代码的“（移动）”第 6 行存在问题。谢谢

// move the spirit left/right/up/down
-(BOOL)moveSpiritWidthOrientation:(GameSpirit*)spirit moveEnum:(GameMoveEnum)move setTransform:(BOOL)trans{
    CGPoint gridPoint = [self getGridPointWithPoint:spirit.endPoint];
    CGAffineTransform transform = CGAffineTransformIdentity;
    switch (move) {
        case GameMoveTopEnum:
            gridPoint.y -= 1;
            transform = CGAffineTransformMakeRotation(-M_PI/2);
            break;
        case GameMoveBottomEnum:
            gridPoint.y += 1;
            transform = CGAffineTransformMakeRotation(M_PI/2);
            break;
        case GameMoveLeftEnum:
            gridPoint.x -= 1;
            transform = CGAffineTransformMakeScale(-1, 1);
            break;
        case GameMoveRightEnum:
            gridPoint.x += 1;
            break;
    }

使用default. 甚至default: break;会做。
