objective c - Got warning "Incorrect decrement of the reference count of an object that is not owned at this point by the caller" -

when 'analyse', got warning "incorrect decrement of reference count of object not owned @ point caller" in this. (xcode 4.1+)

i can understant it's better "kill" object it's proper class, there way outside without warning?

thanks!

nslog(@"--[%s:%d]",__pretty_function__, __line__); myappdelegate* appdelegate = [[uiapplication sharedapplication] delegate];    if (appdelegate.referencespopup != nil) {         [appdelegate.referencespopup release]; // warning         appdelegate.referencespopup = nil;      }       } 

most likely, way in acquiring object being stored in referencespopup, did not allocate or retain it. in case, not responsible releasing it. can set ivar nil.
