In Cocoa, creating classes to encapsulate everything Cocoa relies heavily on calls into the objective c runtime library at “/usr/lib/libobjc.A.dylib”. When trying to use that lib in iOS, it hard crashes. Does anyone know how I can access the objective c runtime library in iOS?
As a side note - is there a way to view crash logs from the iOS simulator or iOS in general?
in the simulator look at the Debug > Open System Log item
Seems other have encountered that before : http://stackoverflow.com/questions/8112035/libobjc-a-dylib-compile-error-on-ios-4-3
Seems the search in the iOS dev library is broken, so I could not locate libobjc there.
Yeah I saw that exact conversation when I was doing some googling of the problem. Unfortunately it doesn’t have any info relevant to this as far as I could tell.
What’s your declare look like?
The best way would be to find out with the iOS dev library reference. I can’t believe this is broken.
Declares:
soft declare function objc_allocateClassPair lib "/usr/lib/libobjc.A.dylib" (superclass as Ptr, name as CString, extraBytes as Integer) as Ptr
soft declare sub objc_registerClassPair lib "/usr/lib/libobjc.A.dylib" (cls as Ptr)
soft declare function class_addMethod lib "/usr/lib/libobjc.A.dylib" (cls as Ptr, name as Ptr, imp as Ptr, types as CString) as Boolean
I found a few things googling
libobjc site:developer.apple.com/library/iosIt looks like soft declares are broken on the simulator (and perhaps the device). Please file a bug report.
I’d also recommend switching to use non-soft declares in cases where you know the function will be available at runtime.
Excellent. Thanks. I will file a bug report soon unless someone beats me to it.
