iphone - 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3.2 to 3.0 and even occasionally 2.x, I frequently get deprecated warnings involving methods that have changed or been superseded: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

Since I yet can not add a comment to the @samiq post, I think I will expand it. Input mentioned directive before a function / method in which you use deprecated stuff. Then you can restore the previous setting after the definition of the function end:

#pragma GCC diagnostic push 
#pragma GCC diagnostic ignored "-Wdeprecated-declarations"
- (void) methodUsingDeprecatedStuff {
    //use deprecated stuff
}
#pragma GCC diagnostic pop
