How do I weak link frameworks on Xcode 4?
问题 I need to weak link some framework with my target. But I can\'t find how to do it... If I try to run my project on 3.2 iPad simulator i get the following error: dyld: Library not loaded: /System/Library/Frameworks/iAd.framework/iAd Reason : Image not found Thanks ! 回答1: Go to your project -> Targets -> Build Phases -> Link Binary with Libraries. Then change the library you want to weak-link from "Required" to "Optional". 回答2: This doesn't work now. Please follow the link below: https:/
