To fix this issue I have only a rather dirty solution for this, as apple does not support it with a public api. My implemention works quit good and should not crash if some api changes in the future (just will not work anymore). I am subclassing the UITableView and adding my own callbacks to the sectionIndex View on the time it is added as a subview to the table.
code :
@interface MyTableView : UITableView

@end

@implementation MyTableView

- (void)selectionStarted {
    [self setSectionIndexColor:[UIColor greenColor]];
}

- (void)selectionStoped {
    [self setSectionIndexColor:[UIColor redColor]];
}

- (void)addSubview:(UIView *)view {
    [super addSubview:view];
    if ([NSStringFromClass([view class]) isEqualToString:@"UITableViewIndex"] && [view isKindOfClass:[UIControl class]]) {
        UIControl *cont = (UIControl *)view;
        [cont addTarget:self action:@selector(selectionStarted) forControlEvents:UIControlEventTouchDown];
        [cont addTarget:self action:@selector(selectionStoped) forControlEvents:UIControlEventTouchUpInside];
        [cont addTarget:self action:@selector(selectionStoped) forControlEvents:UIControlEventTouchUpOutside];
        [cont addTarget:self action:@selector(selectionStoped) forControlEvents:UIControlEventTouchCancel];
    }
}

@end

it should still fix some issue Never use indexPath numbers directly to address cells and sections in a switch/case. It's hard to handle when you want add/remove a row/section in the middle. Instead create an enum which have all sections and use an array that contains sections to be shown. You can have cell or section properties like cell identifiers or height in that enum.
code :
enum FileDetailsCell: Printable {
    case FileName, Location, Size

    var description: String {
        switch self {
        case .FileName: return "noname"
        case .Location: return"Location"
        case .Size: return "Size"
        }
    }

    var defaultValue: String {
        switch self {
        case .Location: return "/"
        case .Size: return "Unknown"
        default: return ""
        }
    }

    var cellIdentifier: String {
        switch self {
        case .FileName: return "fileNameCell"
        default: return "detailCell"
        }
    }
}
var cellsArray: [FileDetailsCell] = [.FileName, .Size]
func numberOfSectionsInTableView(tableView: UITableView) -> Int {
    return 1;
}

func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
    return cellsArray.count;
}

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cellInfo = cellsArray[indexPath.row]

    let cell = tableView.dequeueReusableCellWithIdentifier(cellInfo.cellIdentifier, forIndexPath: indexPath) as! UITableViewCell
    switch cellInfo {
        case .FileName:
            cell.textLabel?.text = item.fileName;
        case .Location:
            cell.textLabel?.text = cellInfo.description
            cell.detailTextLabel?.attributedText = item.locationFormatted ?? cellInfo.defaultValue;
        case .Size:
            cell.textLabel?.text = cellInfo.description
            cell.detailTextLabel!.text = item.size ?? cellInfo.defaultValue;
    }

    return cell
}

Hope this helps You need to customize your design a bit by adding an extra Container UIView into the cell which will add virtual gap from the right of the cell, and keep the cell transparent. See below in the image

wish of those help I’ve found a solution in this thread.
Long story short: You have to set self.tableView.sectionHeaderHeight = 0.0 as well as self.tableView.sectionFooterHeight = 0.0 i.e. in viewDidLoad.
Set the width of the SectionIndex displaying on the right side of the UITableView?

this one helps. Unfortunately, customizing the section index is not possible using the public APIs.
You'll probably end up creating a custom section index view if this feature so important for your app.
