UITableView delegate methods are not called when added on GooeySlideMenu - ios

I want to add UITableView on top of UIView which is a subclass of GooeySlideMenu. As in example shown in git I created UITableView instead of UIButtons but delegate methods are not called.
Below is my code for reference:
class GooeySlideMenu: UIView {
fileprivate var _option: MenuOptions
fileprivate var keyWindow: UIWindow?
fileprivate var blurView: UIVisualEffectView!
fileprivate var helperSideView: UIView!
fileprivate var helperCenterView: UIView!
fileprivate var diff: CGFloat = 0.0
fileprivate var triggered: Bool = false
fileprivate var displayLink: CADisplayLink?
fileprivate var animationCount: Int = 0
fileprivate var myTableView: tableViewCustomClass = tableViewCustomClass()
init(options: MenuOptions) {
_option = options
if let kWindow = UIApplication.shared.keyWindow{
keyWindow = kWindow
let frame = CGRect(
x: -kWindow.frame.size.width/2 - options.menuBlankWidth,
y: 0,
width: kWindow.frame.size.width/2 + options.menuBlankWidth,
height: kWindow.frame.size.height)
super.init(frame:frame)
} else {
super.init(frame:CGRect.zero)
}
setUpViews()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
override func draw(_ rect: CGRect) {
let path = UIBezierPath()
path.move(to: CGPoint(x: 0, y: 0))
path.addLine(to: CGPoint(x: frame.width-_option.menuBlankWidth, y: 0))
path.addQuadCurve(to: CGPoint(x: frame.width-_option.menuBlankWidth, y: frame.height), controlPoint: CGPoint(x: frame.width-_option.menuBlankWidth+diff, y: frame.height/2))
path.addLine(to: CGPoint(x: 0, y: frame.height))
path.close()
let context = UIGraphicsGetCurrentContext()
context?.addPath(path.cgPath)
_option.menuColor.set()
context?.fillPath()
}
func trigger() {
if !triggered {
if let keyWindow = keyWindow {
keyWindow.insertSubview(blurView, belowSubview: self)
UIView.animate(withDuration: 0.3, animations: { [weak self] () -> Void in
self?.frame = CGRect(
x: 0,
y: 0,
width: keyWindow.frame.size.width/2 + (self?._option.menuBlankWidth)!,
height: keyWindow.frame.size.height)
})
beforeAnimation()
UIView.animate(withDuration: 0.7, delay: 0.0, usingSpringWithDamping: 0.5, initialSpringVelocity: 0.9, options: [.beginFromCurrentState,.allowUserInteraction], animations: { [weak self] () -> Void in
self?.helperSideView.center = CGPoint(x: keyWindow.center.x, y: (self?.helperSideView.frame.size.height)!/2);
}, completion: { [weak self] (finish) -> Void in
self?.finishAnimation()
})
UIView.animate(withDuration: 0.3, animations: { [weak self] () -> Void in
self?.blurView.alpha = 1.0
})
beforeAnimation()
UIView.animate(withDuration: 0.7, delay: 0.0, usingSpringWithDamping: 0.8, initialSpringVelocity: 2.0, options: [.beginFromCurrentState,.allowUserInteraction], animations: { [weak self] () -> Void in
self?.helperCenterView.center = keyWindow.center
}, completion: { [weak self] (finished) -> Void in
if finished {
let tapGesture = UITapGestureRecognizer(target: self, action: #selector(GooeySlideMenu.tapToUntrigger))
self?.blurView.addGestureRecognizer(tapGesture)
self?.finishAnimation()
}
})
// animateButtons()
myTableView.reloadData()
triggered = true
}
} else {
tapToUntrigger()
}
}
}
extension GooeySlideMenu {
fileprivate func setUpViews() {
if let keyWindow = keyWindow {
blurView = UIVisualEffectView(effect: UIBlurEffect(style: _option.blurStyle))
blurView.frame = keyWindow.frame
blurView.alpha = 0.0
helperSideView = UIView(frame: CGRect(x: -40, y: 0, width: 40, height: 40))
helperSideView.backgroundColor = UIColor.red
helperSideView.isHidden = true
keyWindow.addSubview(helperSideView)
helperCenterView = UIView(frame: CGRect(x: -40, y: keyWindow.frame.height/2 - 20, width: 40, height: 40))
helperCenterView.backgroundColor = UIColor.yellow
helperCenterView.isHidden = true
keyWindow.addSubview(helperCenterView)
backgroundColor = UIColor.clear
keyWindow.insertSubview(self, belowSubview: helperSideView)
addUItableView()
// addButton()
}
}
fileprivate func addUItableView(){
myTableView.frame = CGRect(x: 0, y: 20, width: 300, height: 200)
myTableView.backgroundColor = UIColor.white
myTableView.delegate = tableViewCustomClass() as? UITableViewDelegate
myTableView.dataSource = tableViewCustomClass() as? UITableViewDataSource
addSubview(myTableView)
}

You need to declared tableview's delegate on tableViewCustomClass's class instead of GooeySlideMenu class .
In tableViewCustomClass
self.delegate = self in tableViewCustomClass's initialiser method

Swift - Problem with scrollview (Need to print when dragging down)

I am testing the swiping controller/gesture from Jake Spracher with his SnapchatSwipeView (https://github.com/jakespracher/Snapchat-Swipe-View )
I have setup a topVC,leftVC,rightVC and middleVC(the main VC).
I manage to capture when the user swipe from the center to the rightVC or to the left VC, with this :
func scrollViewDidScroll(_ scrollView: UIScrollView) {
if delegate != nil && !delegate!.outerScrollViewShouldScroll() && !directionLockDisabled {
let newOffset = CGPoint(x: self.initialContentOffset.x, y: self.initialContentOffset.y)
self.scrollView!.setContentOffset(newOffset, animated: false)
}
if (scrollView.contentOffset) == CGPoint(x: 750.0, y: 0.0) {
print ("TEST OK LEFT!")
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "loadRinkbox"), object: nil)
}
if (scrollView.contentOffset) == CGPoint(x: 0.0, y: 0.0) {
print ("TEST OK LEFT!")
}
if (scrollView.contentOffset) == CGPoint(x: -750.0, y: 0.0) {
print ("TEST OK RIGHT")
}
if (scrollView.contentOffset) == CGPoint(x: 375, y: 0.0) {
print ("TEST OK!")
}
}
But I cannot manage to capture when the user swipe from the centerVC to the topVC, and from topVC to centerVC. I have tried a lot of things but I didn't manage to do it.
My code is for swift 4.
For clarity, I put here the two full swift files. Many, million thanks for those that can help me !

} else {

}
}
}
In MiddleScrollViewController.swift, make the controller conform to UIScrollViewDelegate:
class VerticalScrollViewController: UIViewController,
SnapContainerViewControllerDelegate,
UIScrollViewDelegate {
In that class, in setupScrollView(), set the delegate:
func setupScrollView() {
scrollView = UIScrollView()
// set the delegate to self
scrollView.delegate = self
// the rest of the existing code...
Still in that class, implement didScroll (or whatever other delegate funcs you want to handle):
func scrollViewDidScroll(_ scrollView: UIScrollView) {
print("Vertical Scroll - contentOffset:", scrollView.contentOffset)
}
Now you should get lots of print lines in the debug console when you scroll vertically:
Vertical Scroll - contentOffset: (0.0, 561.0)
Vertical Scroll - contentOffset: (0.0, 560.0)
Vertical Scroll - contentOffset: (0.0, 559.0)
Vertical Scroll - contentOffset: (0.0, 558.0)
If you want your SnapContainerViewController class to be informed when vertical scrolling takes place, you'll probably want to use a new protocol/delegate so VerticalScrollViewController can send that information.

Custom view doesn't appear for the first time swift

When user open my app for the first time, my custom view doesn't appear. But the next time it works fine.
I am calling this view when user taps on button.
let menu = MenuView(image: image, title: "text", buttons: buttons)
menu.show(animated: true)
Custom View code
class MenuView: UIView, Menu {
var background = UIView()
var blackOverlay = UIView()
convenience init(image: UIImage, title: String, buttons: [UIButton]) {
self.init(frame: UIScreen.main.bounds)
setupView(image: image, title: title, buttons: buttons)
}
#objc func cancelTapped() {
hide(animated: true)
}
override init(frame: CGRect) {
super.init(frame: frame)
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func setupView(image: UIImage, title: String, buttons: [UIButton]) {
blackOverlay.backgroundColor = UIColor.black.withAlphaComponent(0.5)
blackOverlay.frame = CGRect(x: 0, y: 0, width: frame.width, height: frame.height)
addSubview(blackOverlay)
let backgroundWidth = self.frame.width - CGFloat(80.0)
let imageView = UIImageView(frame: CGRect(x: (backgroundWidth/2)-17, y: 40, width: 34, height: 34))
imageView.image = image
imageView.contentMode = .center
background.addSubview(imageView)
let titleLabel = UILabel()
let stringHeight = title.stringHeight + 14
titleLabel.frame = CGRect(x: background.center.x+8, y: 100, width: backgroundWidth-16, height: stringHeight)
titleLabel.font = UIFont.systemFont(ofSize: 15, weight: .regular)
titleLabel.text = title
titleLabel.textAlignment = .center
titleLabel.numberOfLines = 0
background.addSubview(titleLabel)
var newHeight: CGFloat = 0
for i in 0...buttons.count-1 {
buttons[i].frame.origin = CGPoint(x: 0, y: titleLabel.frame.height + 125 + CGFloat(i*50))
buttons[i].frame.size = CGSize(width: backgroundWidth, height: 50)
buttons[i].setTitleColor(.gingerColor, for: .normal)
buttons[i].setTitleColor(UIColor.gingerColor.withAlphaComponent(0.5), for: .highlighted)
buttons[i].titleLabel?.textAlignment = .center
newHeight+=buttons[i].frame.height
let separator = UIView()
separator.frame.origin = CGPoint(x: 0, y: titleLabel.frame.height + 125 + CGFloat(i*50))
separator.frame.size = CGSize(width: frame.width, height: 1)
separator.backgroundColor = UIColor(hexString: "dedede")
background.addSubview(separator)
if i == buttons.count-1 {
buttons[i].setTitleColor(UIColor(hexString: "9E9E9E"), for: .normal)
}
buttons[i].addTarget(self, action: #selector(self.cancelTapped), for: .touchUpInside)
background.addSubview(buttons[i])
}
background.frame.origin = CGPoint(x: center.x, y: frame.height)
background.frame.size = CGSize(width: frame.width-80, height: 90 + titleLabel.frame.height+imageView.frame.height + CGFloat(newHeight))
background.backgroundColor = .white
background.layer.cornerRadius = 16
background.layer.masksToBounds = true
addSubview(background)
}
}
and my custom view protocol & extension code:
protocol Menu {
func show(animated: Bool)
func hide(animated: Bool)
var blackOverlay: UIView { get }
var background: UIView { get }
}
extension Menu where Self: UIView {
func show(animated: Bool) {
self.blackOverlay.alpha = 0
self.background.alpha = 0
self.blackOverlay.center = self.center
self.background.center = CGPoint(x: self.center.x, y: self.frame.height+self.background.frame.height/2)
UIApplication.shared.delegate?.window??.rootViewController?.view.addSubview(self)
if animated {
UIView.animate(withDuration: 0.33, animations: {
self.blackOverlay.alpha = 1
self.background.alpha = 1
})
UIView.animate(withDuration: 0.33, delay: 0, usingSpringWithDamping: 0.7, initialSpringVelocity: 10, options: UIViewAnimationOptions(rawValue: 0), animations: {
self.background.center = self.center
}, completion: { (completed) in
print("completed is \(completed)")
})
} else {
self.blackOverlay.alpha = 1
self.background.alpha = 1
self.background.center = self.center
}
}
func hide(animated: Bool) {
if animated {
UIView.animate(withDuration: 0.33, animations: {
self.blackOverlay.alpha = 0
self.background.alpha = 0
})
UIView.animate(withDuration: 0.33, delay: 0, usingSpringWithDamping: 1, initialSpringVelocity: 10, options: UIViewAnimationOptions(rawValue: 0), animations: {
self.background.center = CGPoint(x: self.center.x, y: self.frame.height + self.background.frame.height/2)
}, completion: { (completed) in
self.removeFromSuperview()
})
} else {
self.removeFromSuperview()
}
}
}
As you can see I have a parameter completed in completion animation block, it returns false for the first time. All subsequent times it returns false
I found my mistake.
I tried to present my custom view controller above rootController. But, for the very first time user's rootcontroller is the first screen of onboarding. So, my custom view tried to be shown on another controller.

Swift - Not seeing my custom view class called from another custom view class

Just trying to follow some youtube tutorials and learn about custom views. I am sure I am missing something very basic here. After reading here and the net for hours I am giving up.
I have a custom view that slides out. I am planning on filling it with different custom views as needed. The slideOutView displays fine. However, I am not able to see the other custom view called FlashCardView inside it. I am calling FlashCardView from SlideOutView.
Thanks for the help!

Animate a circle from the center in Swift

I have a circle that I'm animating. It works except that the drawing is from the top left.. Can I animate it from the center? If so, any help would be appreciated..
My code for drawing the circle is:
class CircleView: UIView {
override func draw(_ rect: CGRect)
{
let prefs: UserDefaults = UserDefaults.standard
lineWidthFloat = prefs.value(forKey: "lineWidth") as! Float
let circleSize = Double(lineWidthFloat * 100)
let context = UIGraphicsGetCurrentContext()
context!.setLineWidth(10.0)
context!.setFillColor(UIColor.black.cgColor)
let rect = CGRect(x: 20, y: 20, width: circleSize, height: circleSize)
context!.addEllipse(inRect: rect)
context!.fillPath()
}
}
Thanks!

let circleView = CircleView(frame: CGRect(x: 40, y: 50, width: 40, height: 60))
circleView.backgroundColor = UIColor.clear
view.addSubview(circleView)
self.circleView = circleView
let button = UIButton(frame: CGRect(x: 20, y: 150, width: 80, height: 40))

button.setTitleColor(UIColor.blue.withAlphaComponent(0.3), for: .highlighted)
button.addTarget(self, action: #selector(ViewController.animateCircle), for: .touchUpInside)
view.addSubview(button)
self.button = button
}
#objc func animateCircle() {
circleView?.resizeCircleWithPulseAinmation(30, duration: 1.5)
}
}
Result
You should be able to do it a lot simpler using the transform property.
func pulse() {
UIView.animate(withDuration: 0.5, animations:{
self.circleView.transform = CGAffineTransform(scaleX: 1.2, y: 1.2)
}, completion: { _ in
UIView.animate(withDuration: 0.5, animations: {
self.circleView.transform = .identity
})
})
}

how to add scrollview in custom uiview so that added uiview will scroll

Below is my code which I am using from a custom view referred from
PeriscommentView
However I want to show the entire cells and user can able to scroll, I have unhide the cells by commenting some codes however I don't know how to add a scrollview to this view so that cells added to it can be scrolled.
import UIKit
public class PeriscommentView: UIView {
private var visibleCells: [PeriscommentCell] = []
private var config: PeriscommentConfig
convenience override init(frame: CGRect) {
let config = PeriscommentConfig()
self.init(frame: frame, config: config)
}
required public init(coder aDecoder: NSCoder) {
self.config = PeriscommentConfig()
super.init(coder: aDecoder)!
}
init(frame: CGRect, config: PeriscommentConfig) {
self.config = config
super.init(frame: frame)
}
override public func willMoveToSuperview(newSuperview: UIView?) {
super.willMoveToSuperview(newSuperview)
setupView()
}
private func setupView() {
self.backgroundColor = config.layout.backgroundColor
}
public func addCell(cell: PeriscommentCell) {
cell.frame = CGRect(origin: CGPoint(x: 0, y: self.frame.height), size: cell.frame.size)
visibleCells.append(cell)
self.addSubview(cell)
UIView.animateWithDuration(self.config.appearDuration, delay: 0, options: UIViewAnimationOptions.CurveEaseOut, animations: { () -> Void in
let dy = cell.frame.height + self.config.layout.cellSpace
for c in self.visibleCells {
let origin = c.transform
let transform = CGAffineTransformMakeTranslation(0, -dy)
c.transform = CGAffineTransformConcat(origin, transform)
}
}, completion: nil)
UIView.animateWithDuration(self.config.disappearDuration, delay: self.config.appearDuration, options: UIViewAnimationOptions.CurveEaseIn, animations: { () -> Void in
// cell.alpha = 0.0
}) { (Bool) -> Void in
// cell.removeFromSuperview()
// self.visibleCells.removeAtIndex(self.visibleCells.indexOf(cell)!)
}
}
public func addCell(profileImage: UIImage, name: String, comment: String) {
let rect = CGRect.zero
let cell = PeriscommentCell(frame: rect, profileImage: profileImage, name: name, comment: comment, config: self.config)
self.addCell(cell)
}
}
I have tried editing the code and its floating the views however I don't want it I want to have a proper scroll.
