UITableViewDataSource for NSArray. A UITableViewDataSource for data represented as NSArray being displayed in a UITableView.

Concept and code is from this great objc.io article.

Additionally supports:

• multiple cell identifiers
• cell editing (deletion only)
• sections, with nested NSArrays as data source (use subclass APLArrayWithSectionsDataSource)

Installation

Usage

Import header file:

#import "ALArrayDataSource.h"

Declare a dataSource property:

@property (nonatomic, strong) ALArrayDataSource* dataSource;

Init dataSource with your data array (empty here), cell identifier, a block for configuring the tableView cells and set the tableView dataSource:

self.dataSource = [[ALArrayDataSource alloc] initWithItems:@[] cellIdentifier:@"CellIdentifier" configureCellBlock:[self configureCell]];
self.tableView.dataSource = self.dataSource;

Declare a method returning a block for configuring the tableView cell:

- (TableViewCellConfigureBlock)configureCell {
    return ^(UITableViewCell* cell, id yourModel) {
        cell.textLabel.text = yourModel.name;
        cell.imageView.image = yourModel.image;
    };
}

When you retrieve new data, update your dataSource and tableView like this:

self.dataSource.items = modelArray;
[self.tableView reloadData];
