How do I remove the borders of a UITableView?

Question

In a grouped table view, setting separatorStyle doesn't do anything. If you want to hide it, just do the following:

tableView.separatorColor = [UIColor clearColor];

Use this

tableView.separatorStyle = UITableViewCellSeparatorStyleNone;

To remove the border of a table view write this line:

self.myTableView.separatorColor = [UIColor clearColor];

If you want to remove both the border of a table view but the border between cells too, you have to write both lines:

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

This did the trick for me:

[dayTableView setSeparatorColor:[UIColor whiteColor]]; //or your background color

swift 4 use

myTableView.separatorStyle = UITableViewCellSeparatorStyle.none
