在我的UITableView中选择一个单元格时，选择似乎是随机的

I have a UITableView I create programatically, along with the cells, that displays a list of fonts the user can choose from to change the font they read with. Upon tapping a cell in the tableview, however, the font family sent back with the delegate is not the font that is displayed in the cell. One minute tapping "Times New Roman" will change it to Helvetica, and the next it will change it to Baskerville.I have a UITableView I create programatically,
