BWSwipeRevealCell

Using the library

There are two main classes available - BWSwipeCell and BWSwipeRevealCell

BWSwipeCell - Only contains the pan gesture handling, and is useful mainly for heavy customization through subclassing if all you need is a leg up on swipe interactions

BWSwipeRevealCell - Is an out of the box solution that lets you set images and colors for 1 action on the left and right of the table cell. BWSwipeRevealCell is a subclass of BWSwipeCell.

BWSwipeRevealCell Example

After setting BWSwipeRevealCell as your table cell's type in the storyboard and setting a delegate. Use this code in your controller:

func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
    let cell = tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath)
    let swipeCell:BWSwipeRevealCell = cell as! BWSwipeRevealCell
    swipeCell.bgViewLeftImage = UIImage(named:"Done")!.imageWithRenderingMode(.AlwaysTemplate)
    swipeCell.bgViewLeftColor = UIColor.greenColor()
    swipeCell.bgViewRightImage = UIImage(named:"Delete")!.imageWithRenderingMode(.AlwaysTemplate)
    swipeCell.bgViewRightColor = UIColor.redColor()
    swipeCell.type = .SpringRelease
    return cell
}

Customizing through the interface

BWSwipeCell Properties

var type:BWSwipeCellType

Can be .SpringRelease, .SwipeThrough or .SlidingDoor. Defaults to .SpringRelease

var revealDirection: BWSwipeCellRevealDirection

Can be .Both, .Left or .Right. Defaults to .Both

(readonly) var state: BWSwipeCellState

Can be .Normal, .PastThresholdLeft or .PastThresholdRight

var threshold: CGFloat

The point at which pan elasticity starts, and state changes. Defaults to the height of the UITableViewCell (i.e. when it form a perfect square)

(readonly) var progress:CGFloat

A number between 0 and 1 to indicate progress toward reaching threshold in the current swiping direction. Useful for changing UI gradually as the user swipes.

var shouldExceedThreshold: Bool

Control whether or not the cell pans past the threshold point

var panElasticityFactor: CGFloat

Control how much elasticity there is past threshold, if it can be exceeded. Default is 0.7 and 1.0 would mean no elastic resistance

var animationDuration: Double

Animation duration. Defaults to 0.2

weak var delegate: BWSwipeCellDelegate?

Set the delegate on the cell

BWSwipeRevealCell Properties

var bgViewInactiveColor: UIColor

var bgViewLeftColor: UIColor

var bgViewRightColor: UIColor

Colors for inactive, and activated states for left and right

var bgViewLeftImage: UIImage?

var bgViewRightImage: UIImage?

Images for the left and right actions

Roadmap

Some brief ideas on ways to improve this library

v 0.1.0

• Release as Cocoapod

v 0.x.0

• Fix bugs
• More code commentary
• Identify and remove any code redundancy

v 1.0.0

• Any breaking changes (protocol, method names etc)

v x.0.0

• Customizable interaction per side (i.e. left .SwipeThrough, right .SlidingDoor)
• Possible subclass for allowing .SlidingDoor to convert to .SwipeThrough past a threshold point (see Mail.app)
