Remove SeparatorInset on iOS 8 UITableView for XCode 6 iPhone Simulator

I found a weird white space on

UITableView
for iPhone 6 Simulator (iOS 8) on XCode 6 GM. I have tried to set the
SeparatorInset
from both storyboard and also the code, but the white space is till there.

The following code works on iOS 7 but not on iOS 8 (iPhone 6 simulator).

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
[tableView setSeparatorInset:UIEdgeInsetsZero];
}
}


I attached screen shot below:

iPhone 6 Simulator weird white space on tableview

I am using AutoLayout by the way. I hope someone can show me a way to remove the weird white space on the
TableView
.

Answer

Thanks Student for pointing me to the right direction with the comment "Try this self.myTableView.layoutMargins = UIEdgeInsetsZero;" This line of code will only work on iOS 8 because layoutMargins is only available from iOS 8. If I run the same code on iOS 7, it will crash.

@property(nonatomic) UIEdgeInsets layoutMargins
Description   The default spacing to use when laying out content in the view.
Availability  iOS (8.0 and later)
Declared In   UIView.h
Reference UIView Class Reference

Below is the right answer to solve this weird white space by setting the tableview layoutMargins and cell layoutMargins as UIEdgeInsetsZero if it exists (for iOS 8). And it will not crash on iOS 7 as well.

-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{

    if ([tableView respondsToSelector:@selector(setSeparatorInset:)]) {
        [tableView setSeparatorInset:UIEdgeInsetsZero];
    }

    if ([tableView respondsToSelector:@selector(setLayoutMargins:)]) {
        [tableView setLayoutMargins:UIEdgeInsetsZero];
    }

   if ([cell respondsToSelector:@selector(setLayoutMargins:)]) {
        [cell setLayoutMargins:UIEdgeInsetsZero];
   }
}
