Purpose

I recently needed to build the iMessage style pull-to-reveal timestamps feature for a personal project and decided to open source the implementation.

Installation

Simply add the following to your Podfile:

Latest release uses Swift 5: pod RevealableCell

If you need Swift 2.2: pod 'RevealableCell', '1.1'

If you need Swift 3.0: pod 'RevealableCell', '2.0'

Then add the following import at the top of your source file(s):

Swift import RevealableCell Obj-C @import RevealableCell

Usage

In order to use RevealableCell in your application, follow the steps below:

1. Your cell must be a subclass of RevealableTableViewCell

2. You must register a nib or a RevealableView subclass using:

   tableView.registerNib(nib, forRevealableViewReuseIdentifier: "identifier") or tableView.registerClass(revealableViewClass, forRevealableViewReuseIdentifier: "identifier")

3. In cellForRowAtIndexPath you can dequeue and configure an instance using:

   if let view = tableView.dequeueReusableRevealableViewWithIdentifier("identifier") as? MyRevealableView {
     view.titleLabel.text = "" // configure
     cell.setRevealableView(view, style: .Slide, direction: .Left)
   }
   

This new implementation, provides reusable views of the same type as well as allowing you to have different styles or directions for individual cells.

Run this project, to see a demo similar to the iMessage app on your iOS device.

Additional Info

RevealableViews also support AutoLayout now, so if you've setup your constraints correctly, the views will auto-size their widths (per cell) for you. However, you can also specify a fixed width for each cell using

cell.revealableView.width = 100

Note: The height will always be the same as the cell and the position is based on the .style of the RevealableView

Feel free to use in any way you see fit. Please try and reference me somewhere in your app if you use this in a production app and maybe even tell me about it via Twitter @shaps ;)
