For the nonexistent method warnings, your project- or target-level settings likely have "Undeclared Selector" checked in the GCC warnings section of the build settings.
For the multiple selectors warnings, look at the Strict Selector Matching item in the same section. It says this will pop up if you're trying to send the message to a variable of type id, vs to an explicit class type.
