这是iOS7模拟器中应用程序在没有任何用户交互的情况下运行时的样子(同时我没有运行任何我的代码,只有Cocos2D的样板代码):
5.0->6.1版本没有这种问题。产生此问题的代码为Cocos2D样板代码,我试图通过注释来最小化它,并且这是App delegate中的最小代码。
我在
从Instruments看到的结果也是一样的。
不幸的是,无法在设备上测试iOS 7,但我不认为模拟器会像那样表现。
更新:
我进行了2个标记生成,以下是结果。
所有项目都是那些64字节的分配。我不知道它们是什么类型。值得一提的是,我使用的是最新稳定的Cocos2D 2.1。
更新#2:
64字节分配的调用堆栈。

启动时注释掉了CCDirector
,以消除我的代码。所以现在应用程序启动时,我只看到黑屏上的帧速率。从Instruments看到的结果也是一样的。

正在使用手动内存管理,并且我已经将其源文件设置为-fno-objc-arc
。请注意,这只会在iOS7上发生。 - Pablo
