UItableview Separator line's height

问题

Can I adjust the height of the UITableview's separator line? I add UIView at the cell to use as separator line and its good, the problem is that when I slide the cell to delete it, the delete button is the problem, its overlapping the separator line, or can I adjust the delete button's height?

回答1:

If you can't resize the delete button, resize your bottom UIView so it can overlap the delete button.

The code pasted in by Rashad is pretty old (found here) and doesn't seem to work for iOS 7 or iOS 8.

Here is updated code that works:

-(void)layoutSubviews {

    UIView *deleteButtonView = nil;

    for (UIView *subview in self.subviews) {
        // find the delete view in iOS 8
        if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationView"]){
            deleteButtonView = subview;
            break;
        }

        // find the delete view in iOS 7
        if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellScrollView"]) {
            for (UIView *secondSubview in [subview subviews]) {
                if ([NSStringFromClass([secondSubview class]) isEqualToString:@"UITableViewCellDeleteConfirmationView"]) {
                    deleteButtonView = secondSubview;
                    break;
                }
            }
        }
    }

    int heightOffset = 5;
    CGRect buttonFrame = deleteButtonView.frame;
    buttonFrame.origin.y = heightOffset;
    buttonFrame.size.height = self.frame.size.height-2*heightOffset;
    deleteButtonView.frame = buttonFrame;
}

I always draw separator line like a subView on contentView of cell. And disable separatorStyle in tableView. And customise delete button like here: https://stackoverflow.com/a/22396248/887325

In you TableViewCell layoutSubviews method write this:

if ([NSStringFromClass([subview class]) isEqualToString:@"UITableViewCellDeleteConfirmationControl"]) {
    UIView *deleteButtonView = (UIView *)[subview.subviews objectAtIndex:0];
    CGRect newf = deleteButtonView.frame;
    newf.origin.x = 250;
    newf.origin.y = 47;
    newf.size.width = 30;
    newf.size.height = 50;

    deleteButtonView.frame = newf;
}

Hope this helps.. :)
