getting started with ios

[Christopher Scott]

Turns out this is working:

TagLib::ID3v2::Frame *frame =l[i];
tag->removeFrame(frame);

I thought I included i386 but I am getting errors when compiling for the sim.  Though, it works fine on the device and ultimately this is the goal … so I happy with this so far.  Later I will look at what is going on that i386 isn’t getting included.  I am new to cmake and it’s processes so I will leave this for a rainy day or if I need to support it later.

While his code works for his project, because I believe that he is not hitting the remove case, I have tested it and it’s bothering me that it’s not working correctly.  The code looks for a PRIV frame and is suppose to remove it.  I think what is going wrong with the code that my coworker wrote is it’s trying to remove the frameListMap entry and not the actual frame.

If I comment out the "tag->removeFrame(l[i]);” line in the code below, I stop getting errors, but then if there is a previous priv frame with uits data, this code adds a second entry to the priv tag.  Chances are that the track files that my app downloads will never contain a priv tag or uits data (unless I put it there already), but it would be nice to know that the code is only allowing one entry in the priv frame.
