iOS 8 UITableView separator inset 0 not working

Question

I have an app where the UITableView\'s separator inset is set to custom values - Right 0, Left 0. This works perfectly in iOS 7.

You can use UIAppearance once, at your application startup (before UI is loaded), to set it as default global settings:

// iOS 7:
[[UITableView appearance] setSeparatorStyle:UITableViewCellSeparatorStyleSingleLine];
[[UITableView appearance] setSeparatorInset:UIEdgeInsetsZero];

[[UITableViewCell appearance] setSeparatorInset:UIEdgeInsetsZero];

// iOS 8:
if ([UITableView instancesRespondToSelector:@selector(setLayoutMargins:)]) {

    [[UITableView appearance] setLayoutMargins:UIEdgeInsetsZero];
    [[UITableViewCell appearance] setLayoutMargins:UIEdgeInsetsZero];
    [[UITableViewCell appearance] setPreservesSuperviewLayoutMargins:NO];

}

This way, you keep your UIViewController's code clean and can always override it if you want.
