The length of the UITableView split line is controlled by the length of the uitableview

The length of the UITableView split line is controlled by the length of the uitableview

The default cell split line of UITableView is not full on the left, but full on the right. This display is ugly. I need to make the left and right sides of it not full, the distance is 20 pixels

 

// code1    if ([self.tableView respondsToSelector:@selector(setSeparatorInset:)]) {        [self.tableView setSeparatorInset:UIEdgeInsetsMake(0, 20, 0, 20)];    }// code2     if ([self.tableView respondsToSelector:@selector(setLayoutMargins:)]) {        [self.tableView setLayoutMargins:UIEdgeInsetsMake(0, 20, 0, 20)];    }

 

Add a proxy method for UITableView:

- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{    if ([cell respondsToSelector:@selector(setSeparatorInset:)])    {        [cell setSeparatorInset:UIEdgeInsetsMake(0, 15, 0, 15)];    }    if ([cell respondsToSelector:@selector(setLayoutMargins:)])    {        [cell setLayoutMargins:UIEdgeInsetsMake(0, 15, 0, 15)];    }}

 

Ode1 code:
Customize the frame of the cell split line

Code at code2:
-LayoutMargins returns a set of insets from the edge of the view's bounds that denote a default spacing for laying out content.
If preservesSuperviewLayoutMargins is YES, margins cascade down the view tree, adjusting for geometry offsets, so that setting the left value of layoutMargins on a superview will affect the left value of layoutMargins for subviews positioned close to the left edge of their superview's bounds
If your view subclass uses layoutMargins in its layout or drawing, override-layoutMarginsDidChange in order to refresh your view if the margins change.
