objective c - Xcode 7 iOS 9 UITableViewCell Separator Inset issue

Question

This is not a question, rather a solution to the problem I faced.

In Xcode 7, when the application is run on iOS 9 on iPad devices, the UITableViewCell leaves some margin onto the left side of the UITableView. And rotating the device to the landscape would increase the margins.

The solution I found is:

Setting cellLayoutMarginsFollowReadableWidth to NO.

self.tbl_Name.cellLayoutMarginsFollowReadableWidth = NO;

This property is only available in iOS 9. So, you will have to put a condition to check the iOS version, else it will crash.

if (NSFoundationVersionNumber > NSFoundationVersionNumber_iOS_8_1)
{
    self.tbl_Name.cellLayoutMarginsFollowReadableWidth = NO;
}

Answer 1

iOS 9 and above:

This is because of a new feature called readable content guides. It provides margins that are suitable for reading. So, on iPhone and portrait iPad they are very small margins. But in the landscape, iPad they are bigger. In iOS 9, UITableViewCell margins default to following the readable content guide.

If you want to stop that, just set the tableView's cellLayoutMarginsFollowReadableWidth to NO/false.
