UITableViewCell Animation

Hello friends,
This article is use for UITableViewCell animation.
In most of the application for represent data you can use UITableView.
When UITableView represent at that time you need to animated UITableViewCell for best UI experience of application.

How to use
You need to implement UITableView method 

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
     
        ///Animation code
    
    }

Now you need to developed FadeIn animation like this

cell.alpha = 0
        UIView.animate(withDuration: 0.1, delay: (0.1 * Double(indexPath.row)),  animations: {
            cell.alpha = 1.0
        }, completion: nil)

For more animation see this video



For above animation I have created extension for UITableViewCell

extension UITableViewCell{
    
    /// Table view cell fade in animation for best way to represent
    /// tableview
    ///
    /// - Parameters:
    ///   - duration: animation duration default value 0.1
    ///   - index: cell index
    func fadeInAnimation(withDuration duration: Double = 0.1,forIndex index : Int) {
        self.alpha = 0
        UIView.animate(withDuration: duration, delay: (duration * Double(index)),  animations: {
            self.alpha = 1.0
        }, completion: nil)
    }
    
    /// Table view cell bounce animation for best way to represent
    /// tableview
    ///
    /// - Parameters:
    ///   - duration: animation duration default value 0.8
    ///   - delay: animation delay default value 0.05
    ///   - index: cell index
    func bouncingAnimation(withDuration duration: Double = 0.8,withDelay delay : Double = 0.05,forIndex index : Int) {
        self.transform = CGAffineTransform(translationX: 0, y: self.frame.height)
        UIView.animate(withDuration: duration,delay: delay * Double(index),usingSpringWithDamping: 0.8,initialSpringVelocity: 0.1,animations: {
            self.transform = CGAffineTransform(translationX: 0, y: 0)
        })
    }
    
    /// Table view cell move in animation for best way to represent
    /// tableview
    ///
    /// - Parameters:
    ///   - duration: animation duration default value 0.5
    ///   - delay: animation delay default value 0.08
    ///   - index: cell index
    func moveInAnimation(withDuration duration: Double = 0.5,withDelay delay : Double = 0.08,forIndex index : Int) {
        self.alpha = 0
        self.transform = CGAffineTransform(translationX: 0, y: self.frame.height / 2)
        UIView.animate(withDuration: duration,delay: delay * Double(index),animations: {
            self.alpha = 1
            self.transform = CGAffineTransform(translationX: 0, y: 0)
        })
    }
    
    /// Table view cell right side to in animation for best way to represent
    /// tableview
    ///
    /// - Parameters:
    ///   - duration: animation duration default value 0.5
    ///   - delay: animation delay default value 0.08
    ///   - index: cell index
    func rightInAnimation(withDuration duration: Double = 0.5,withDelay delay : Double = 0.08,forIndex index : Int) {
        self.transform = CGAffineTransform(translationX: self.bounds.width, y: 0)
        UIView.animate(withDuration: duration,delay: delay * Double(index),animations: {
            self.transform = CGAffineTransform(translationX: 0, y: 0)
        })
    }
    
    /// Table view cell left side to in animation for best way to represent
    /// tableview
    ///
    /// - Parameters:
    ///   - duration: animation duration default value 0.5
    ///   - delay: animation delay default value 0.08
    ///   - index: cell index
    func leftInAnimation(withDuration duration: Double = 0.5,withDelay delay : Double = 0.08,forIndex index : Int) {
        self.transform = CGAffineTransform(translationX: -self.bounds.width, y: 0)
        UIView.animate(withDuration: duration,delay: delay * Double(index),animations: {
            self.transform = CGAffineTransform(translationX: 0, y: 0)
        })
    }
}

And you can simply use like 

func tableView(_ tableView: UITableView, willDisplay cell: UITableViewCell, forRowAt indexPath: IndexPath) {
        if (animationType == .bounce){
            cell.bouncingAnimation(forIndex: indexPath.row)
        }else if (animationType == .moveIn){
            cell.moveInAnimation(forIndex: indexPath.row)
        }else if (animationType == .leftIn){
            cell.leftInAnimation(forIndex: indexPath.row)
        }else if (animationType == .rightIn){
            cell.rightInAnimation(forIndex: indexPath.row)
        }else if (animationType == .side){
            if (indexPath.row % 2 == 0){
                cell.leftInAnimation(forIndex: indexPath.row)
            }else{
                cell.rightInAnimation(forIndex: indexPath.row)
            }
        }else{
            cell.fadeInAnimation(forIndex: indexPath.row)
        }
    }

The sample code for illustrated in this post is available on GitHub. 

Thank you.

Animation

Animation interaction is best way to deal with different type of interact with application functionality. Now a days Animation is big part of Application for success.
In this article you can create easy way to animated object in Swift Xcode.
If you want to object zoomin, zoomout, move, roted. bounce etc.,

Example of code :

import UIKit

enum Axis {
    case x
    case y
    case both
}
extension UIView{
    func zoomAnimation(withDuration duration: Double, withZoomLevel zoomLevel: CGFloat, complition : ((Bool) -> Swift.Void)?)  {
        UIView.animate(withDuration: duration, animations: {
            self.transform = CGAffineTransform(scaleX: zoomLevel, y: zoomLevel)
        }) { _ in
            UIView.animate(withDuration: duration, animations: {
                self.transform = CGAffineTransform(scaleX: 1.0, y: 1.0)
            },completion : {_ in
                complition?(true)
            })
        }
    }
    
    func rotedAnimation(withDuration duration: Double,withAngle angle : CGFloat,withRepetation isRepeat:Bool , complition : ((Bool) -> Swift.Void)?) {
        if isRepeat
        {
            UIView.animate(withDuration: duration, delay: 0.0, options: .repeat, animations: {
                self.transform = self.transform.rotated(by: angle)
            }) { _ in
                complition?(true)
            }
        }
        else
        {
            UIView.animate(withDuration: duration, animations: {
                self.transform = self.transform.rotated(by: angle)
            }, completion: {_ in
                complition?(true)
            })
        }
    }
    
    func moveAnimation(withDuration duration : Double,withAxis axis:Axis,withAnimStepCount step:CGFloat,complition : ((Bool) -> Swift.Void)?) {
        let oldFrame = self.frame
        UIView.animate(withDuration: duration, animations: {
            if axis == .both
            {
                self.frame.origin.x += step
                self.frame.origin.y += step
            }
            else if axis == .y
            {
                self.frame.origin.y += step
            }
            else
            {
                self.frame.origin.x += step
            }
        }) { _ in
            UIView.animate(withDuration: duration, animations: {
                self.frame = oldFrame
            }, completion: { _ in
                complition?(true)
            })
        }
    }
    
    func bounceAnimation(withDuration duration : Double,withAxis axis:Axis,withBounceStepCount step:Int,withAxisStepCount bounceStep : CGFloat ,complition : ((Bool) -> Swift.Void)?) {
        let oldFrame = self.frame
        UIView.animate(withDuration: duration/Double(step), animations: {
            if axis == .x
            {
                self.frame.origin.x  += bounceStep
            }
            else
            {
                self.frame.origin.y += bounceStep
            }
        }, completion: { _ in
            UIView.animate(withDuration: duration/Double(step), animations: {
                if axis == .x
                {
                    self.frame.origin.x -= (bounceStep * 2)
                }
                else
                {
                    self.frame.origin.y -= (bounceStep * 2)
                }
            },completion:{_ in
                complition?(true)
                UIView.animate(withDuration: duration/Double(step), animations: {
                    self.frame.origin.x = oldFrame.origin.x
                    self.frame.origin.y = oldFrame.origin.y
                    
                },completion:{_ in
                    complition?(true)})
            })
        })
    }
}


You can put above code in file and easy to use
-> for example zoom-in object then

obj.zoomAnimation(withDuration: 1.0, withZoomLevel: 0.5, complition: nil)

-> zoom-out

obj.zoomAnimation(withDuration: 1.0, withZoomLevel: 1.5 ,complition: {_ in
            print("zoom complition")
        })

-> Bounce 

        sender.bounceAnimation(withDuration: 1.0, withAxis: .x, withBounceStepCount: 10, withAxisStepCount: 20, complition: nil)
