I have copy pasted my tabbarviewcontroller.m file and my tab4VC.h files below.
my question is this. My app works fine. I click a recipe and it goes into a tab bar view controller that has 4 tabs at the bottom, my audio that I want to play are in tab 4. when i first open by app and go to row 0 and section 0 the audio plays fine when I first click the play button. but when i go to access row 1 section 0 my audio file doesn't play, Also when i try to return to my row 0 section 0 tab 4, the audio doesn't play again. I hope I'm not being confusing with the wording. Any feedback is greatly appreciated. Please let me know if I also need to upload any other files, however I am confident that the problem is arising somewhere in the 2 files listed below, maybe my if statements are the problem?
