UITableView，分隔符颜色在哪里设置？

Question

I have added a UITableView in IB and set the "delegate" and "datasource" and all is working well. What I wanted to do next was change the separator color, but the only way I could find to do this was to add the method to one of the delegate callbacks, is there a better place I should put this?

I don't have this at the moment but I was thinking that maybe I need to add an "iVar" from my controller that I can link to the UITableView in IB and then set separator color in the viewDidload ?

-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
    [tableView setSeparatorColor:[UIColor blackColor]];
    return 65;
}

Answer 1

- (void)viewDidLoad
{
   [self.tableView setSeparatorColor:[UIColor myColor]];
}

I hope that helps - you'll need the self. to access it, remember.

Swift 4.2

tableView.separatorColor = UIColor.red

Answer 2

Now you should be able to do it directly in the IB.

Not sure though, if this was available when the question was posted originally.

Answer 3

Swift version:

override func viewDidLoad() {
    super.viewDidLoad()

    // Assign your color to this property, for example here we assign the red color.
    tableView.separatorColor = UIColor.redColor()
}

Answer 4

Try + (instancetype)appearance of UITableView:

Objective-C:

[[UITableView appearance] setSeparatorColor:[UIColor blackColor]]; // set your desired colour in place of "[UIColor blackColor]"

Swift 3.0:

UITableView.appearance().separatorColor = UIColor.black // set your desired colour in place of "UIColor.black"

Note: Change will reflect to all tables used in application.

Answer 5

If you just want to set the same color to every separator and it is opaque you can use:

 self.tableView.separatorColor = UIColor.redColor()

If you want to use different colors for the separators or clear the separator color or use a color with alpha.

BE CAREFUL: You have to know that there is a backgroundView in the separator that has a default color.

To change it you can use this functions:

    func tableView(tableView: UITableView, willDisplayHeaderView view: UIView, forSection section: Int) {
        if(view.isKindOfClass(UITableViewHeaderFooterView)){
            var headerView = view as! UITableViewHeaderFooterView;
            headerView.backgroundView?.backgroundColor = myColor

           //Other colors you can change here
           // headerView.backgroundColor = myColor
           // headerView.contentView.backgroundColor = myColor
        }
    }

    func tableView(tableView: UITableView, willDisplayFooterView view: UIView, forSection section: Int) {
        if(view.isKindOfClass(UITableViewHeaderFooterView)){
            var footerView = view as! UITableViewHeaderFooterView;
            footerView.backgroundView?.backgroundColor = myColor
           //Other colors you can change here
           //footerView.backgroundColor = myColor
           //footerView.contentView.backgroundColor = myColor
        }
    }

Hope it helps!
