Is there a way to remove the separator line from a UITableView?

Question

You can do this with the UITableView property separatorStyle. Make sure the property is set to UITableViewCellSeparatorStyleNone and you're set.

Objective-C

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

In Swift (prior to 3)

tableView.separatorStyle = .None

In Swift 3/4/5

tableView.separatorStyle = .none

You can do this in the storyboard / xib editor as well. Just set Seperator to none.

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.tableView setSeparatorStyle:UITableViewCellSeparatorStyleNone];
}

I still had a dark grey line after attempting the other answers. I had to add the following two lines to make everything "invisible" in terms of row lines between cells.

self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.separatorColor = [UIColor clearColor];

In interface Builder set table view separator "None"

and those separator lines which are shown after the last cell can be remove by following approach. Best approach is to assign Empty View to tableView FooterView in viewDidLoad

self.tableView.tableFooterView = UIView()

In Swift:

tableView.separatorStyle = .None
