Screen becoming black when moving from one tab bar to another

Question

My Program has a tab bar view controller containing two tabs. each tab contains a table and when clicking on each cell, a new view is loaded. But when i go back to the main view after going into the cell, the screen becomes black. I can move to the other tab now but the same process repeats.Can someone please tell me why this is happening ??
