Indexing Alphabet Slider iOS

Overview

This class allows to add an alphabet slider to your TableView or CollectionView controllers for better movement through the list. (Like the iOS contact list)

Initialization

	NSMutableArray *anArrayOfItems = [NSMutableArray array];
	AlphabetView *alphabetView = [[AlphabetView alloc] initWithFrame:CGRectMake(x , y, width, height) letters:anArrayOfItems heightLetter:20.0];
    alphabetView.delegate = self;
    [aView addSubview:alphabetView];

2. anArrayOfItems is an array that contains the items list sort by the first character ( Ex : [@"Alice Ung",@"Bob Lint",@"John Doe"])
3. aView is the parent which we attach this view.

Delegation & Movement

@interface AViewController : UITableViewController<AlphabetDelegate>

-(void)alphabetDelegate:(NSInteger)index{
    [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForRow:index inSection:0]
                          atScrollPosition:UITableViewScrollPositionTop
                                  animated:NO];
}
