I found a bug when using both AutoLayout and UITableViewController in iOS 7
You can put
-viewDidLayoutSubviews, and you’ll see that it works well in
iOS 8. However, when you test it in
iOS 7, you’ll find you can’t even scroll the TableView!!!
After hours of digging in SO, I couldn’t find any satisfactory solutions yet. Most of them exclaim that it’s an unsolved big bug in iOS 7, which might be related to
-topLayoutGuide. Finally, someone says using an embeded
UITableView instead of
UITableViewController can deal with this problem. I tried and it worked well indeed!!!
