Objective-C call C ++ Code new article objective-C call C ++ code

In my previous objective-C call C ++ code, I used a very stupid method to implement simple, small objective-C call C/C ++CodeIn this example, when I learned objective-C serialization and deserialization on the Internet today, I accidentally met a good solution: IOS developed a method to get the local IP address, this demo can obtain the IP address of the Internet of the mobile phone. I have not tested it on a real machine, but it can be used on a virtual machine.
The specific code will not be pasted. Download objective-cto use c&c.zip.
