Are you trying to change this system wide or just for your own process? I found some sample code (ComplexPlayThru ) that does just that, among other things. I want to incorporate the switching into my app, so I added some of the files from that project to my project via drag/drop from the finder.
I doubt very seriously that the ComplexPlayThru app is what you want to base your code on. There's a lot more going on there than just device management.
You definitely don't want to just use the code in the project as it is very specialized for that project. Rather, what you want to do is study the code, understand it, and translate it into your app. I only need to reference one of the headers in my project, (I think), but when I do that, I get a slew of errors pointing not only to the referenced header, but to the headers referenced by it. I'm doing something wrong here, I'm sure, but I don't know what. I thought one or both of these compiler settings might help, but no dice: Compile soure as: According to file type // All the files have the .cpp extension. C language dialect: Compiler default. // I changed this from the default to another setting and got the same errors
There are a number of C++ settings, but most of these were checked by default, I enabled others, but still the same errors. I've read on the list and in the archives threads of this nature, but could not find anything that helped. This might be more of an Xcode question, I have emailed that list, but thought I would try here again anyway. I got no substantive answers the first time.
I remember your last email. I did in fact respond, looking for more information about what you are trying to do. So far, you haven't answered that question at all. Now, all I really need to do is switch the input device, so if someone knows of a simpler way to do this, I'm all ears. I'm sure I don't need all of this code, but I can whittle things down once I get a better handle on CA.
I'd really like to see a lot more info about what your application is trying to do and what APIs you are using to accomplish that. The answer to your question very much hinges on this information.
