the crash log is: Assertion failure in void PushNextClassForSettingIMP(id, SEL()). Terminating app due to uncaught exception 'NSInternalInconsistencyException'

for ipad. i run 'p class_getInstanceMethod(aClass, @selector(setBackgroundColor:))' the console can't output the function address. but for iPhone. i can get the address.

so i tried 'p class_getInstanceMethod(aClass, @selector(_setBackgroundColor))'

problem solved..

but it's just so strange. if you konw other soluetion. please let me konw.

The same crash with me, and I resolved it use UIView instead of UITableView.
