Hybrid programming in Apple system development (1): mutual calls between Objective-C and C ++, and mutual calls between flex and js

Hybrid programming in Apple system development (1): mutual calls between Objective-C and C ++, and mutual calls between flex and js
First, OC calls the C ++ code. Create an Objective-C Project and create the c ++ file MyCppFile. hpp and MyCppFile. cpp.

Change the file name of the Cpp Code to the mm extension. The structure of the project code is as follows:

 

Code for implementing C ++: MyCppFile. hpp MyCppFile. cpp can be called by introducing the C ++ header file in main. mm:

 

Then, C ++ first creates an OC-related file by calling OC, and then modifies *. m to *. mm.

 

The header file is written in the C format.

Write the specific implementation with OC.

Similarly, you can call it by introducing the header file in C ++.

 

The call between OC and C ++ is simpler than expected. The key here is to change the extension of the OC file to *. mm.
