Command: ios hooking set return_value

Usage: ios hooking set return_value "<full class & selector>" <true/false>

Hooks into a specified Objective-C method and sets its return value to
either True or False. This is useful in cases where simple methods are used
to determine things like 'Should SSL pinning be enabled?' as an example.

Examples:
   ios hooking set return_value "+[JailbreakDetection isJailbroken]" false
   ios hooking set return_value "-[SecurityHelper shouldPinSSL:]" true
