CRMultiRowSelect

CRMultiRowSelect is a custom UITableViewCell for iOS that supports multiple row selection in a UITableViewController.

Customize the color you want in just one line of code.

Everything is drawn with CoreGraphics NO IMAGES, so it supports Retina Display and looks beauty.

How To Use

  • Add CRTableViewCell.m and CRTableViewCell.h files to your XCode Project
  • In your UITableViewController.h add your 'selected marks' NSMutableArray:
@interface YourTableViewController : UITableViewController
{
    NSArray *dataSource;
    NSMutableArray *selectedMarks; // You need probably to save the selected cells for use in the future.
}
  • Customize your cellForRowAtIndexPath method implementation:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CRTableViewCellIdentifier = @"cellIdentifier";

    // init the CRTableViewCell
    CRTableViewCell *cell = (CRTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CRTableViewCellIdentifier];

    if (cell == nil) {
        cell = [[CRTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CRTableViewCellIdentifier];
    }

    // Check if the cell is currently selected (marked)
    NSString *text = [dataSource objectAtIndex:[indexPath row]];
    cell.isSelected = [selectedMarks containsObject:text] ? YES : NO;
    cell.textLabel.text = text;

    return cell;
}
  • Customize your didSelectRowAtIndexPath method implementation:
 - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    NSString *text = [dataSource objectAtIndex:[indexPath row]];

    if ([selectedMarks containsObject:text])// Is selected?
        [selectedMarks removeObject:text];
    else
        [selectedMarks addObject:text];

    [tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}
  • You can customize the mark color using a HEX color, just change this line in the CRTableViewCell.m file
#define kMarkColor                  kBlueColor // or your HEX color, example: 0xfff000
  • Optionally you can get the selected cells using your previous declared NSMutableArray (example):
- (void)done:(id)sender
{
    NSLog(@"%@", selectedMarks);
}
  • Also, you can refer to the Demo Example in the CRTableViewController.m file

Requirements

  • Xcode 4.3 or higher
  • LLVM compiler
  • iOS 4.3 or higher
  • CoreGraphics Framework
  • ARC
