问题
It can dump the runtime headers of private frameworks of iOS by class-dump tool. but I'm looking for the headers of the IOHIDEvent which has been moved to any where that I can not find after iOS 6. But, in the iOS 6 SDK there is lib looks like it:
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS6.1.sdk/System/Library/Extensions/IOHIDFamily.kext/PlugIns/IOHIDLib.plugin
How can I dump the headers of the IOHIDLib?
回答1:
class-dump is a tool that lets you reverse engineer Objective-C binaries. But, it looks to me like IOHIDLib is a C/C++ library, so class-dump won't help you there:
$ class-dump -H IOHIDLib
2013-06-14 02:55:39.104 class-dump[4676:707] Unknown load command: 0x0000002a
2013-06-14 02:55:39.106 class-dump[4676:707] Unknown load command: 0x0000002b
2013-06-14 02:55:39.109 class-dump[4676:707] Warning: This file does not contain any Objective-C runtime information.
Luckily, IOHIDEvent appears to be part of the open-source part of iOS. You can find headers (and .cpp file) for it here.
I don't know what you're trying to do with it, but if it's some basic touch event handling, you might try using GSEvent. There's a good bit more documentation for that, especially if you search on stackoverflow.
