Vertical / Horizontal Scrolling DataGrid for iOS

1. Extract files from zip archive.
2. Open your project.
3. In project tree right-click at your project root. Choose Add Files to your project. Select EXDataGridFramework folder. Select "Copy items into destination group folders" option and choose "Create group for any added folders".
4. If you are using ARC – go to the project properties and choose Build Phases - Compiled sources. Add -fno-objc-arc to each .m file of DataGrid.
5. Import “EXDataGrid.h” to your view controller.
6. Create instance of EXDataGrid class in your loadView: 
 see Initialization section;
7. Implement at least all required methods from DataGridDelegate protocol: see Delegate implementation section.

EXDataGrid dataGrid = [[EXDataGrid alloc] init];
dataGrid.frame = frame; 
dataGrid.dataGridDelegate = self; //set delegate
[self.view addSubview:dataGrid]; //and add data grid as subview
[dataGrid release]; 

//define number of columns in data grid
- (int)numberOfColumnsInDataGrid:(EXDataGrid*)dataGrid;
{
    return [dataSource count];
}
//define number of rows in each column
- (int)numberOfRowsInDataGrid:(EXDataGrid *)dataGrid
{
    return [[dataSource lastObject] count];
}
//If you want to set different height for different rows 
- (float)dataGrid:(EXDataGrid *)dataGrid heightOfRow:(int)rowNumber
{
    if(rowNumber == 0) {
      return 40;
    } else if (rowNumber == 1) {
      return 50;
    } else {
      return 60;
    }
}

//You can set different width for different columns
(float)dataGrid:(EXDataGrid *)dataGrid widthOfColumn:(int)columnNumber {
    if(columnNumber == 0) {
        return 100;
    } else if (columnNumber == 1) {
        return 110;
    } else {
        return 120;
    }
}
//Customize cell appearance. Inherit you cell from EXDataGridCell class.
- (EXDataGridCell*)dataGrid:(EXDataGrid *)dataGrid cellForColumn:(int)columnNumber row:(int)rowNumber
{
//obtain existing cell
    EXDataGridCell *cell = (EXDataGridCell*)[dataGrid  cellDequeueReusableIdentifier:identifier              forColumn:columnNumber];
    if(!cell)  {
        cell = [[[EXDataGridCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];
    }
    //set data to the each cell
    NSArray *columnData = [dataSource objectAtIndex:columnNumber];
    [cell.textLabel setText:[columnData objectAtIndex:rowNumber]];
    return cell;
}

• If your data source was changed, call reloadData / reloadColumn / reloadRow depending on what has changed.
• To drag a column, hold your finger on a header of that column. After short time columns becomes more transparent and you can move it into another location. To select a column, press header of that column.
