After reading it, we found that libz1.2.3.dylib in the framework is lost,

 

Search and find that this is a system component. As long as the app is used, upgrade it to libz1.2.5.dylib on the iPhone 5.

 

Some people may not know how to reference it at the beginning.

Just paste a few images.

 

Click the plus sign. Enter libz. Then, it is referenced ..
