AFNetworking: current deployment target does not support automatic links

I am using Xcode 4.6.2 and also I am new to iOS development. I try to install the AFNetworking library, but I get the following error when I try to use it: "The current deployment target does not support automated _weak references" (when I try to display the image from the URL) in the AFHTTPClient and AFURLConnectionOperation .

I do not have weak properties in my small first project, but only in strong ones.

Any advice would be great!

thanks

Weak links are only supported with iOS 5.0 and later. If the deployment target is set to 4.3, you cannot use weak . The error probably came from AFNetworking.

Drop support for iOS 4.3 if you may or may not use AFNetworking.

To target an older OS, you can use unsafe_unretained instead of weak in the property declaration, and it should work basically the same. weak references are null when their target leaves, but unsafe_unretained leaves open the possibility that the object you are communicating with may turn into a dangling pointer when it is freed. The latter is the same behavior as if you were using assign as a property declaration in manual memory management.
