Cocos2d iphone cocos2d 1.0.1，用于解决带有Catalina的iMac 5K上的Mac文本输出问题

我已经为mac开发了一个带有CoCoS2D1.0.1的mac应用程序

文本显示（

CCLabelTTF

）在带有Catalina的iMac 5K上不起作用

Mac pro、iMac和MacBook都没有问题

我认为这个代码是个问题

CCE2D.m：

已定义elif（允许使用MAC操作系统X版本） -（id）initWithString:（NSString*）字符串维度：（CGSize）维度对齐：（CCTextAlignment）对齐属性string:（NSAttributedString*）stringWithAttributes { NSAssert（stringWithAttributes，@“无效的stringWithAttributes”）

对于（int i=0；i噢，是的~~解决了~
