The documentation is rather poorly written when talking about playing audio in the background. It gives the impression that all you have to do to continue playing the audio that you are currently playing is to just add a key/value pair to the info.plist file and wallah, it's magic.

I've read that using drawRect instead of adding subviews to the cell could improve performance. First question: Is that true? Second question: If it will increase p...
