SWRevealTableViewCell

SWRevealTableViewCell is UITableViewCell subclass to easily display left and right buttons based on user pan gestures or developer programmatic actions. Similar to the iOS8 mail app and but with enhanced features.

Features

• Support for any combination of left/right utility buttons.
• Works both on iOS7 and iOS8, no issues
• Full in and out animations of utility buttons with damper effect.
• Buttons are specified by providing an array of SWCellButtonItems, similar to UIToolBarItems.
• Items can have text, images or both.
• Configurable item sizes on an individual basis.
• Item action is provided by calling a handler block.
• Convenience UIActionSheet category method 'showFromCellButtonItem:animated:' to display menus from items
• Correct handling of rotations, and cell/table resizing.
• No issues with transparency, background colors or images on cells or table views.
• No issues with accessory views on cells.
• API easier than a UIToolbar.
• Seamless integration of a pan gesture recognizer, behaving as smooth as silk.
• Comprehensive set of delegate methods for getting full state of the controller and implementing your own code hooks for customizing behavior.
• Lightweight, clean, easy-to-read, self-documenting code that you will enjoy using in your projects.

Basic Functionality

Left and right 'cellButtonItems' with optional 'performsActionOnOverdraw' feature, imitating iOS8 mail app feedback animation for deleting cells

Items can be stacked 'first on top' (default) or 'last on top' (like iOS8 mail app). The following gif shows button items stacked as if they were behind the cell.

Works well with transparency and visual effects on cells and button items. No issues either with tableViewCell accessory views.

Examples

The repo includes the following example projects that can be used as templates or for testing purposes

• RevealTableViewCellExample.xcodeproj

              

Requirements

• iOS 7.0 or later.
• Objective-C, ARC.

Usage

The SWRevealTableViewCell repository attempts to provide an updated cocoaPods file and consistent tag versioning, but it is not actively updated on the cocoapods-specs repository.

The easiest way to install it is by copying the following to your project:

• SWRevealTableViewCell.h
• SWRevealTableViewCell.m

On your project:

• Initialize instances of SWRevealTableViewCell on your cellForRowAtIndexPath or register the SWRevealTableViewCell for use with you table view
• In cellForRowAtIndexPath set the dataSource and optionally the delegate for SWRevealTableViewCell instances.
• Implement the following two datasource methods to return an array of SWCellButtonItems
  • (NSArray*)leftButtonItemsInRevealTableViewCell:(SWRevealTableViewCell *)revealTableViewCell
  • (NSArray*)rightButtonItemsInRevealTableViewCell:(SWRevealTableViewCell *)revealTableViewCell

Basic API Description

Registering a SWRevealTableViewCell for use on your tableView

[tableView registerClass:[SWRevealTableViewCell class] forCellReuseIdentifier:RevealCellReuseIdentifier];

Creating cell instances

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    SWRevealTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:RevealCellReuseIdentifier forIndexPath:indexPath];

    cell.dataSource = self;
    .
    .
}

Providing button items

- (NSArray*)rightButtonItemsInRevealTableViewCell:(SWRevealTableViewCell *)revealTableViewCell
{
    SWCellButtonItem *item1 = [SWCellButtonItem itemWithTitle:@"Delete" handler:^(SWCellButtonItem *item, SWRevealTableViewCell *cell)
    {
        NSLog( @"Delete");
    }];

    item1.backgroundColor = [UIColor redColor];
    item1.tintColor = [UIColor whiteColor];
    item1.width = 75;
    
    return @[item1];
}

Programmatic animation of left/right items. Position can be: SWCellRevealPositionLeft, SWCellRevealPositionCenter, SWCellRevealPositionRight

- (void)setRevealPosition:(SWCellRevealPosition)revealPosition animated:(BOOL)animated;

Other methods are documented in the SWRevealTableViewCell.h header file.
