How to compile specific files in objective-c++ and the rest of the project in objective-c

Question

I\'m currently busy on a project where I need to use an external accessory to read Mifare 1k tags.

The accessory was provided with an SDK, written in (Objective ?)C+

Answer 1

I have resolved this problem:

1. You should set "According to file type" to "Complile Sources As",
2. Set "-ObjC++" to the "Other Linker Flags"
3. The last,you should modify the files's suffix to .mm that reference the library method
