start_get_fps: code == 830472984 about py-ios-device

这个 code 不是绝对值，实际上应该是由 (class 0x31) (subclass 0x80) (code 0xC6) 等多个值决定的，
具体你可以查看 规则文件来去查看对应 display debug code 代表什么

谢谢大佬提示,我找到了相关的内容,如下:

)

这里包含了所有(class 0x31) (subclass 0x80)的event-type,但除了从名字(IOMFB_V2_SWAP_PROGRAM_EXT)推测一些信息之外,我没有找到更多的解释.请问有更近一步关于每个event-type的说明吗?

IOMFB_V2_SWAP_PROGRAM_EXT 类似一个方法意思，遇到了这个 code 规则然后去执行 IOMFB_V2_SWAP_PROGRAM_EXT 这个方法，你可以具体再搜搜这个方法做了什么
