Suppressing deprecated warnings in Xcode

Question

With all the SDKs floating around, it's handy to be able to build for multiple SDKs and platforms. However, bouncing from 3.2 to 3.0 and even occasionally 2.x, I frequently get deprecated warnings involving methods that have changed or been superseded:

warning: 'UIKeyboardBoundsUserInfoKey' is deprecated.

Since I still want to maintain compatibility with older OSes, and I'm also striving to remove 'noise' when building, is there a way to turn off or disable these warnings?

Answer 1

Try -Wno-deprecated.

Answer 2

You can also suppress warnings per file by using

#pragma GCC diagnostic ignored "-Wdeprecated-declarations"

which in turn makes it a little bit better practice than just suppressing all warning once and together... after all you got to know what you are doing it for.
