Python Hello World in PyObjC on iPhone?

问题:

I installed the iphone-python package from Cydia, but the HelloPython app closes immediately when I run it from Springboard.

This may be a red herring, but I found the .py file in Terminal and tried to run it with python and got a python error:

$ python /private/var/stash/Applications.pwn/HelloPython.app/HelloPython.py Traceback (most recent call last):   File "/private/var/stash/Applications.pwn/HelloPython.app/HelloPython.py", line 9, in <module>     import objc   File "/usr/lib/python2.5/objc/__init__.py", line 17, in <module>     _update()   File "/usr/lib/python2.5/objc/__init__.py", line 14, in _update     import _objc ImportError: dlopen(/usr/lib/python2.5/lib-dynload/_objc.dylib, 2): Symbol not found: _OBJC_CLASS_$_Object   Referenced from: /usr/lib/python2.5/lib-dynload/_objc.dylib   Expected in: /usr/lib/libobjc.A.dylib 

I'm running 4.3.3.

How can I get this app working, so I'll have a working example of PyObjC?

回答1:

Well due to the changes in the way executables on the new ios run, the dynamic library has become corrupt. The mach-o will no longer run due to the upgraded objective-c so a workaround would be to compile pyobjc from source and run normaly. The only ptoblem with that is that the iphone's version of pyobjc is built for uikit so you would need to find saurik's (Jay Freeman) source code and compile it. I might do that for myself so ill post back with a deb file if i do.
