在静态库中使用弱引用

Question

I am trying to build a static library which support a deployment target iOS 4.3 and above.

The problem is that my code uses weak references.

Is it anyway possible to only build the library which uses weak references?

Answer 1

There's this library from Plausible Labs that makes this work.

PLWeakCompatibility is a set of stubs that implement the Objective-C runtime functions the compiler uses to make __weak work. It automatically calls through to the real runtime functions if they're present (ie your app is running on iOS5+ or Mac OS X 10.7+) and uses its own implementation if they're not.
