Are you sure that you have a UIImageView stored in _imageView? — Erik Kerber
Could you provide a bit more information on your setup? Is _imageView an instance of UIImageView, and are you including the UIImageView+AFNetworking category provided by AFNetworking somewhere where _imageView could adopt the setImageWithURLRequest:placeholderImage:success:failure method? — rambo
Did you add AFNetworking as Cocoa Pod or as AFNetworking.framework? In any case, make sure the binaries (.a or .framework) are added in the Copy Phase — Adam Mendoza

Ensure that AFNetworking+UIImageView.m (or more likely, all AFNetworking implementation files) has been added to your target.

Click on AFNetworking+UIImageView.m, and select your target under "Target Membership" in the right window.
