imp_implementationForwardingToSelector is a trampoline that forwards an objc message to a different selector.
Installation
imp_implementationForwardingToSelector is available through CocoaPods, to install
it simply add the following line to your Podfile:
pod "imp_implementationForwardingToSelector"How it works
Message forwarding
imp_implementationForwardingToSelector is a custom trampoline (you can read about trampolines here) which can forward any objc message to a new selector.
IMP imp_implementationForwardingToSelector(SEL forwardingSelector, BOOL returnsAStructValue);Here is an example
IMP forwardingImplementation = imp_implementationForwardingToSelector(@selector(setCenter:), NO);
class_addMethod([UIView class], @selector(thisSetCenterDoesNotExistYet:), forwardingImplementation, typeEncoding);and suddenly every instance of UIView responds to -[UIView thisSetCenterDoesNotExistYet:] and forwards this message to -[UIView setCenter:]. If you would like some more information about trampolines and maybe a blog post like Writing custom trampolines for beginners and all the pitfalls, hit me up on Twitter.
Limitations
imp_implementationForwardingToSelector is written in raw assembly which is currently only available on i386, armv7, armv7s and arm64.
