MCSwipeTableViewCell implements the gestural table view cell style seen in the very well-executed Mailbox iOS app.

MCSwipeTableViewCell

An Effort to show how one would implement a TableViewCell like the one we can see in the very well executed Mailbox iOS app.

##Demo ###Exit Mode The exit mode (MCSwipeTableViewCellModeExit) is the original behavior we can see in the Mailboxapp. Swiping the cell should make it disappear.

###Switch Mode The switch mode (MCSwipeTableViewCellModeSwitch) is a new behavior I'm introducing. The cell will bounce back after selecting a state, this allows you to keep the cell. Very useful to switch an option quickly.

##Usage

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    static NSString *CellIdentifier = @"Cell";
        
    MCSwipeTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
    
    if (!cell)
    {
        cell = [[MCSwipeTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
    }
    
    // For the delegate callback
    [cell setDelegate:self];
    
    // We need to provide the icon names and the desired colors
    [cell setFirstStateIconName:@"check.png"
                     firstColor:[UIColor colorWithRed:85.0/255.0 green:213.0/255.0 blue:80.0/255.0 alpha:1.0]
            secondStateIconName:@"cross.png"
                    secondColor:[UIColor colorWithRed:232.0/255.0 green:61.0/255.0 blue:14.0/255.0 alpha:1.0]
                  thirdIconName:@"clock.png"
                     thirdColor:[UIColor colorWithRed:254.0/255.0 green:217.0/255.0 blue:56.0/255.0 alpha:1.0]
                 fourthIconName:@"list.png"
                    fourthColor:[UIColor colorWithRed:206.0/255.0 green:149.0/255.0 blue:98.0/255.0 alpha:1.0]];
    
    // We need to set a background to the content view of the cell
    [cell.contentView setBackgroundColor:[UIColor whiteColor]];
    
    // Setting the type of the cell
	[cell setMode:MCSwipeTableViewCellModeExit];
    
    return cell;
}	

###Delegate

MCSwipeTableViewCell has a delegate to retrieve the cell/state/mode of the triggered item.

@interface MCTableViewController () <MCSwipeTableViewCellDelegate>

#pragma mark - MCSwipeTableViewCellDelegate

- (void)swipeTableViewCell:(MCSwipeTableViewCell *)cell didTriggerState:(MCSwipeTableViewCellState)state withMode:(MCSwipeTableViewCellMode)mode
{
    NSLog(@"IndexPath : %@ - MCSwipeTableViewCellState : %d - MCSwipeTableViewCellMode : %d", [self.tableView indexPathForCell:cell], state, mode);
}

###Deleting cells in Exit mode In MCSwipeTableViewCellModeExit mode you may want to delete the cell with a nice fading animation, the following lines will give you an idea how to execute it:

- (void)swipeTableViewCell:(MCSwipeTableViewCell *)cell didTriggerState:(MCSwipeTableViewCellState)state withMode:(MCSwipeTableViewCellMode)mode
{    
    if (mode == MCSwipeTableViewCellModeExit)
    {
		// Remove the item in your data array and then remove it with the following method
        [self.tableView deleteRowsAtIndexPaths:@[[self.tableView indexPathForCell:cell]] withRowAnimation:UITableViewRowAnimationFade];
    }
}

There is also an example in the demo project, I recommend to take a look at it.

###Customization You may want to change the number of states, have a color without the icon or the opposite. All those combinations are possible.

In setFirstStateIconName: method you just need to put a nil in the required fields to disable a state, remove the color or the icon.

For instance if you only want to have two states out of four:

[cell setFirstStateIconName:@"check.png"
				 firstColor:[UIColor colorWithRed:85.0/255.0 green:213.0/255.0 blue:80.0/255.0 alpha:1.0]
		secondStateIconName:@"cross.png"
				secondColor:[UIColor colorWithRed:232.0/255.0 green:61.0/255.0 blue:14.0/255.0 alpha:1.0]
			  thirdIconName:nil
				 thirdColor:nil
			 fourthIconName:nil
				fourthColor:nil];

##Consideration This library is not compatible with auto-layout so you will need to disable auto-layout in your xib properties.

##Requirements

• iOS >= 5.0
• ARC
