Answer 1

It doesn't look like standard index view is customizable.

In my application I just created custom index view instead of standard one. Basically all you need to do here is track touch position in that view and scroll UITableView accordingly. You may also need to add some visual effects - change view's background color on touch and highlight current section title.

Use this plugin from Hyabusa. Simple replacment for UITableView Index that allows setting of colors

CMIndexBar *indexBar = [[CMIndexBar alloc] initWithFrame:CGRectMake(self.view.frame.size.width-35, 10.0, 28.0, self.view.frame.size.height-20)];
[indexBar setIndexes:[NSMutableArray arrayWithObjects:@"A",@"B",@"C",@"D",@"E",@"F",@"G", nil]];
[self.view addSubview:indexBar];
[indexBar release];

Delegate

- (void)indexSelectionDidChange:(CMIndexBar *)IndexBar:(int)index:(NSString*)title;

Swift version:

tableView.sectionIndexBackgroundColor = UIColor.clearColor() //iOS7+
tableView.sectionIndexTrackingBackgroundColor = UIColor.clearColor() //iOS6+
tableView.sectionIndexColor = UIColor.redColor() //iOS6+

To customize the index view height (UITableViewStylePlain style only):

tableView.sectionIndexMinimumDisplayRowCount = 15
