Remove SeparatorInset on iOS 8 UITableView for Xcode 6 iPhone Simulator

Question

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 fr

Answer 1

In iOS8 you have to set the Inset both on Row and on Table level.

Row level in the cellForRowAtIndexPath:

if ([cell respondsToSelector:@selector(preservesSuperviewLayoutMargins)]){
    cell.layoutMargins = UIEdgeInsetsZero;
    cell.preservesSuperviewLayoutMargins = false;
}

Table level in the viewDidLoad:

[tableReference setSeparatorInset:UIEdgeInsetsZero];

After that it is a good idea to CLEAN your project. On some occasions I noted that these changes were not directly introduced in the executable App in the simulator.

Answer 2

See iOS 8 UITableView separator inset 0 not working

Basically, you need to set both the cell.layoutMargin as well as the tableView's layoutMargin. YMMV, but I had to set the table view up in layoutSubviews before it would work!

Answer 3

Try to create a UITableViewCell class category and add this getter

- (UIEdgeInsets)layoutMargins {
    return UIEdgeInsetsZero;
}

in iOS7 this will not be called cos there's no this property in SDK，and will not cause any crash； in iOS8 this will be called every time you use the cell

It works for me

Answer 4

Workaround for iOS 7 & iOS 8

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{    
    cell.separatorInset = UIEdgeInsetsMake(0.0f, cell.frame.size.width, 0.0f, 0.0f); 
}

Answer 5

I have static UITableView and wanted to shift the margin of a cell separator to the left edge.

Thanks to the above answers, this was my solution

override func tableView(tableView: UITableView, willDisplayCell cell: UITableViewCell, forRowAtIndexPath indexPath: NSIndexPath) {
    // needed to shift the margin a specific cell to the left edge
    if indexPath.section == 3 && indexPath.row == 0 {
        cell.layoutMargins = UIEdgeInsetsZero
        cell.preservesSuperviewLayoutMargins = false
        cell.separatorInset = UIEdgeInsetsMake(0.0, 0.0, 0.0, 0.0)
    }
}

Answer 6

Just add the following:

tableView.separatorStyle = .none
