iOS - MJNIndexView

MJNIndexView is a highly customizable UIControl which displays an alternative index for UITableView. I wanted to mimic the index designed by Jeremy Olson's Tapity for their Languages app. I think their idea of implementing index is brilliant and it is one of the best examples of great UX. I hope more apps are going to use similar indices instead of the generic ones.

Example Code

@interface MJNIndexTestViewController () <MJNIndexViewDataSource>

@property (nonatomic, strong) MJNIndexView *indexView;
@property (nonatomic, strong) NSMutableArray *sectionArray;
@property (nonatomic, strong) UITableView *tableView;

@end

@implementation MJNIndexTestViewController

- (void)viewDidLoad
{
  [super viewDidLoad];

    // initialise tableView
    self.tableView = [[UITableView alloc] initWithFrame:self.view.bounds]   [self.tableView registerClass:[UITableViewCell
    class]forCellReuseIdentifier:@"cell"];
    self.tableView.dataSource = self;
    self.tableView.delegate = self;
    self.tableView.showsVerticalScrollIndicator = NO;
    [self.view addSubview:self.tableView];

    // initialise MJNIndexView
    self.indexView = [[MJNIndexView alloc]initWithFrame:self.view.bounds];
    self.indexView.dataSource = self;
    self.indexView.fontColor = [UIColor blueColor];
    [self.view addSubview:self.indexView];
}

// two methods needed for MJNINdexView protocol
- (NSArray *)sectionIndexTitlesForMJNIndexView:(MJNIndexView *)indexView
{
    return sectionArray;
}

- (void)sectionForSectionMJNIndexTitle:(NSString *)title atIndex:(NSInteger)index;
{
    [self.tableView scrollToRowAtIndexPath:[NSIndexPath indexPathForItem:0  inSection:index] atScrollPosition: UITableViewScrollPositionTop     animated:NO];
}
.
.
.
@end

Usage

Only two files are required for using MJNIndexView: MJNindexView.h & MJNIndexView.m. Copy both of them into your Xcode Project. Make sure to include QuartzCore framework in your target.

Your UIViewController must implement MJNIndexViewDataSource protocol methods. The first one of them is needed to provide the index with all section titles. The second one is needed to provide UIViewController with a title or index number selected by a user.

You can customize the look and behaviour of MJNIndex by tweaking more than 20 parameters. You can experiment with the most of them in the demo app.

If you want to change items in the index or most of its parameters after the MJNIndexView was added to the superView you should use the method – (void)refreshIndexItems to recalculate every item position, size etc.

To do

• Improve a curtain fade (it could behave strange when you use very large value for the right margin).

• Improve performance on older devices

• Cocoapod
