  • Objective-C with some Objective-C++, calling a normal c++ method "referenced from" problem

    - by xenonii
    Hi, I made an Objective-C project for the iPhone. I had only one cpp class, the soundEngine taken from some Apple demo. Now I'm trying to merge OpenFeint which is coded in Objective-C++. As soon as I drop in the code without even referring to it from my code, when I hit Build, my Objective-C code cannot find the methods of the cpp file. All the class files compile, but in the linking stage it says something like: "_SoundEngine_SetDisabled", referenced from: someClass.o Note that it is adding an underscore in front of the methods when it's reporting these linking errors. P.S. I know that for OpenFeint first thing one should do is convert the files to .mm but if possible I don't want to go down that road at this stage of development. I was going to try create a wrapper Objective-C++ class for it. I read someone managed to do that.

  • Interface builder UIButton custom background image not working on simulator/device

    I'm trying to do something really simple. I have an image for a button and I'm trying to set it on a custom button in interface builder.

Just the button's text will appear. Do I need to turn on some flag or something of the sort?
