iOS9中找不到XXX.dylib 与 is unavailable no availabel on ios (app extension)

在 iOS9 中现在找不到 XXX.dylib 了，比如libz.tbd  如果要用到 libz.dylib，可以用下面的办法，来自 Stack Overflow。

  1. Go to Build Phases >Link Binary with Librairies > + > Add other
  2. Once in the file selection window do “CMD”+Shift+G (Go to folder) and type /usr/lib/
  3. From /usr/lib you can add : libz.dylib and more…
  4. Compile and have fun

is unavailable no availabel on ios (app extension) - use view controller

Targers-->Build Settings-->Build Options--> Require Only App-Extension-Safe -->NO
