我正在使用以下代码在屏幕上渲染图像
-(id) init
{
if( (self=[super init] )) {
CGSize winSize = [[CCDirector sharedDirector] winSize];
CCSprite *player = [CCSprite spriteWithFile:@"Player.png" rect:CGRectMake(0, 0, 27, 40)];
player.position = ccp(player.contentSize.width/2, winSize.height/2);
[self addChild:player];
}
return self;
}
当我运行代码时出现以下错误

请帮忙解释为什么会出现此错误
最佳答案
[CCNode addChild:] 使用 NSAssert 让您知道参数不允许为 nil。
确保 player 不为零。
另请注意崩溃前日志中的行。
