iphone - Multiple Methods named '-setTransform:' found - 


-(void)rotateview:(id)sender { cgaffinetransform rotatetransform = cgaffinetransformrotate(cgaffinetransformidentity, m_pi); [sender settransform:rotatetransform];//the error shown here }

i getting caution error shows , says multiple methods named -settransform: found. shows when have #import avfoundation/avfoundation.h in header file. suggestions? thanks

cast sender proper class type , warning should go away:

[(yourclasshere *)sender settransform:rotatetransform];

as sender passed rotateview: type id xcode cannot know actual class type , method call.

edit: coincidentally today matt gallagher of cocoa love fame published article kinds of issues caused calling ambiguous method on id in objective-c.
