I am trying to do my first ever App, and i'm need to add UITapGestureRecognizer that will scale photo in TableViewCell.
And it is works, but not correctly — my Gesture scale not just photo in ViewCell but all elements in ViewCell. How could I fix this?
All my code for TableViewCell:
import UIKit
class PhotosCollectionViewCell: UICollectionViewCell {
static let identifier = "PhotosCollectionViewCell"
#IBOutlet weak var mainPhoto: UIImageView!
#IBOutlet weak var mainLabel: UILabel!
var isInScale: Bool = false
func configure(photo: PhotosInProfile) {
mainPhoto.image = UIImage(named: photo.mainPhoto)
mainLabel.text = "Date: \(photo.date)"
}
override func awakeFromNib() {
super.awakeFromNib()
let doubleTap = UITapGestureRecognizer(target: self, action: #selector(imageDoubleTapped))
doubleTap.numberOfTapsRequired = 2
mainPhoto.isUserInteractionEnabled = true
mainPhoto.addGestureRecognizer(doubleTap)
}
#objc func imageDoubleTapped() {
if isInScale {
self.transform = .identity
} else {
self.transform = CGAffineTransform(scaleX: 1.5, y: 1.5)
}
isInScale.toggle()
}
}
import UIKit
class PhotosCollectionViewCell: UICollectionViewCell {
static let identifier = "PhotosCollectionViewCell"
#IBOutlet weak var mainPhoto: UIImageView!
#IBOutlet weak var mainLabel: UILabel!
var isInScale: Bool = false
func configure(photo: PhotosInProfile) {
mainPhoto.image = UIImage(named: photo.mainPhoto)
mainLabel.text = "Date: \(photo.date)"
}
override func awakeFromNib() {
super.awakeFromNib()
let doubleTap = UITapGestureRecognizer(target: self, action: #selector(imageDoubleTapped))
doubleTap.numberOfTapsRequired = 2
mainPhoto.isUserInteractionEnabled = true
mainPhoto.addGestureRecognizer(doubleTap)
}
#objc func imageDoubleTapped() {
if isInScale {
mainPhoto.transform = .identity
} else {
mainPhoto.transform = CGAffineTransform(scaleX: 1.5, y: 1.5)
}
isInScale.toggle()
}
}

Following is my code to update view height inside tableview cell
override func layoutSubviews() {
super.layoutSubviews()
layout()
}
fileprivate func layout() {
rootFlexContainer.frame.size.width = frame.width - 20
rootFlexContainer.flex.layout(mode: .adjustHeight)
if(rootFlexContainer.frame.height != 0) {
tagsHeight.constant = rootFlexContainer.frame.height
}
}
although this is not reflected till I scroll i.e is cell is recreated. How to update constraint inside TableViewCell of a view?

Following is view hierarchy from stroryboard
A few observations -
1. Unnecessary layoutIfNeeded() call inside awakeFromNib()
override func awakeFromNib() {
super.awakeFromNib()
/*
self.layoutIfNeeded() // Not Necessary, Remove it.
*/
// No other changes to current implementation
}
2. Following should not be necessary, remove it.
/* Not necessary, Remove it.
override func layoutSubviews() {
super.layoutSubviews()
layout()
}
fileprivate func layout() {
rootFlexContainer.frame.size.width = frame.width - 20
rootFlexContainer.flex.layout(mode: .adjustHeight)
if(rootFlexContainer.frame.height != 0) {
tagsHeight.constant = rootFlexContainer.frame.height
}
}
*/
3. In the method, where you populate all the details, make following changes
func setSetupStoreUI() {
// No changes to current implementation
/* Remove this, we will update later
rootFlexContainer.flex.layout()
*/
if retailerTags?.count ?? 0 == 0 {
tagsView.isHidden = true
} else {
tagsView.isHidden = false
}
// Copied as is from `layout()`
rootFlexContainer.frame.size.width = frame.width - 20
rootFlexContainer.flex.layout(mode: .adjustHeight)
if (rootFlexContainer.frame.height != 0) {
tagsHeight.constant = rootFlexContainer.frame.height
}
// do a manual layout (on contentView, NOT self)
self.contentView.layoutIfNeeded()
}
You have to tell the table view controller that your cell height has changed.
Most common methods are protocol/delegate pattern or (swift preferred) closures.
For example...
In your cell class:
class MyTableViewCell: UITableViewCell {
// "callback" closure
var cellHeightChanged: (()->())?
// whatever happens that you need to change the cell height
func heightChanged() -> Void {
tagsHeight.constant = rootFlexContainer.frame.height
cellHeightChanged?()
}
}
Then, in your controller, in cellForRowAt:
cell.cellHeightChanged = {
tableView.performBatchUpdates(nil, completion: nil)
}
I am developing an application in swift 3 with the following interface:
I have to add some details about the legend. The legend consists of two views (firstView and secondView). Where a default "layout" is 0, until we click on it and that is when the detail of the cell is opened. Bells, a legend like this appears:
Currently the slider send events are as follows:
The interface consists of two views. The map that is the view of the bottom ("MainMapVC") that if we make a "swipe" to the right appears the legend of the map "LefSideViewController" formed by custom cells ("customCell").
I enclose the code of the three classes:
The "customCell":

func didTappedSwicht(cell: customCell)
func didMoveSlider(cell: customCell)
}

The application communicates with protocols and delegates. For example, when we click on the swicht of the legend, the class "customCell" is able to detect the event "swichtValueChanged" and send it to a "didTappedSwicht" delegate of "LeftSideViewController", but when we move the slider the "customCell" class is not Able to detect the event "sliderValueChanged" and takes the event to close the view (because the legend on the left is closed with a swipe on the left).
How can I make it to detect the event of the slider and not to close the view?
Thank you
You should bind your Slider with two Events "Primary Action Triggered" and "Touch Up Inside"
Here I attached Image for your reference
and remove left swipe and right swipe gesture on this method
Method Description and code
1 "Primary Action Triggered"
When You click on slider the method will call "Primary Action Triggered"
Note : Disable your gesture
(UISwipeGestureRecognizerDirection.right and UISwipeGestureRecognizerDirection.left)
2 Touch Up Inside

I want the stepper in the View Controller to update the color in my custom UIView every time it is clicked. I'm not sure if the problem is due to the instance of the class or that the values of the variables (redd1, greenn1, and bluee1) are not being changed.
This is my first file:
class ViewController: UIViewController {
var colors = UIView1();
#IBOutlet var redStepper: UIStepper!
#IBOutlet var greenStepper: UIStepper!
#IBOutlet var blueStepper: UIStepper!
#IBAction func redChange(sender: UIStepper)
{
redValue.text = Int(sender.value).description;
colors.redd1 = Double(sender.value);
//self.view.setNeedsDisplay()
}
#IBAction func greenChange(sender: UIStepper)
{
greenValue.text = Int(sender.value).description;
colors.greenn1 = Double(sender.value);
//self.view.setNeedsDisplay()
}
#IBAction func blueChange(sender: UIStepper)
{
blueValue.text = Int(sender.value).description;
colors.bluee1 = Double(sender.value);
//self.view.setNeedsDisplay()
}
}
This is my second file:
class UIView1: UIView {
var redd1 = 0.0;
var greenn1 = 0.0;
var bluee1 = 0.0;
override init(frame: CGRect)
{
super.init(frame: frame)
}
required init?(coder aDecoder: NSCoder)
{
super.init(coder: aDecoder)
}
override func drawRect(rect: CGRect)
{
let circle = UIView(frame: CGRect(x: -75.0, y: -40.0, width: 200.0, height: 200.0))
circle.layer.cornerRadius = 50.0;
let startingColor = UIColor(red: (CGFloat(redd1))/255, green: (CGFloat(greenn1))/255, blue: (CGFloat(bluee1))/255, alpha: 1.0)
circle.backgroundColor = startingColor;
addSubview(circle);
}
}
drawRect is only called when the view is being added, so in your example, drawRect is called once, and not after changing the stepper.
Instead, change your stepper file to:
#IBOutlet var redStepper: UIStepper!
#IBOutlet var greenStepper: UIStepper!
#IBOutlet var blueStepper: UIStepper!
#IBAction func redChange(sender: UIStepper) {
redValue.text = Int(sender.value).description;
colors.redd1 = Double(sender.value);
updateColor()
}
#IBAction func greenChange(sender: UIStepper) {
greenValue.text = Int(sender.value).description;
colors.greenn1 = Double(sender.value);
updateColor()
}
#IBAction func blueChange(sender: UIStepper) {
blueValue.text = Int(sender.value).description;
colors.bluee1 = Double(sender.value);
updateColor()
}
And then add the updateColor function to your UIView1 class:
class UIView1: UIView {
var redd1 = 0.0;
var greenn1 = 0.0;
var bluee1 = 0.0;
func updateColor() {
let circle = UIView(frame: CGRect(x: -75.0, y: -40.0, width: 200.0, height: 200.0))
circle.layer.cornerRadius = 50.0;
let startingColor = UIColor(red: (CGFloat(redd1))/255, green: (CGFloat(greenn1))/255, blue: (CGFloat(bluee1))/255, alpha: 1.0)
circle.backgroundColor = startingColor;
addSubview(circle);
}
}
I would like to create a simple flip effect, but I don't understand the problems I have here :
the whole screen is flipping, not only the view, is there a way to flip the 100,100 square only?
I can only flip twice, then the tap does not work anymore, would you know why?
import UIKit
class ViewController: UIViewController {
var fromOneToTwo : Bool = true
var view1 : UIImageView!
var view2 : UIImageView!
var tap : UITapGestureRecognizer!
func handleTap(tap: UITapGestureRecognizer){
println("1/fromOneToTwo \(fromOneToTwo)")
var v1 = (fromOneToTwo ? self.view1 : self.view2)
var v2 = (fromOneToTwo ? self.view2 : self.view1)
UIView.transitionFromView(v1, toView: v2, duration: 0.5, options: (UIViewAnimationOptions.TransitionFlipFromLeft | UIViewAnimationOptions.CurveEaseInOut) ) { finished in
self.fromOneToTwo = !self.fromOneToTwo
println("2/fromOneToTwo \(self.fromOneToTwo) ")
}
}
func createView( str:String)->UIImageView!{
var img = UIImage(named: str)!
var imgView = UIImageView(frame: CGRectMake(0,0, 200, 200))
imgView.image = img
imgView.sizeToFit()
imgView.userInteractionEnabled = true
imgView.addGestureRecognizer(tap)
return imgView
}
required init(coder aDecoder:NSCoder){
super.init(coder:aDecoder)
tap = UITapGestureRecognizer(target: self, action: "handleTap:")
view1 = createView("imageOnee.png")
view2 = createView("imageTwo.png")
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(view1)
view.addSubview(view2)
view.backgroundColor = UIColor.redColor()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
Also, when I try to add the whole code in a custom UIView, and add the custom instance myViewto the ViewController, the tap does not work at all.
I made this work creating a container view for view1 and view2. The tap recognizer is then added to this container view.
class ViewController: UIViewController {
var fromOneToTwo : Bool = true
var view1 : UIImageView!
var view2 : UIImageView!
var container : UIView!
var tap : UITapGestureRecognizer!
func handleTap(tap: UITapGestureRecognizer){
println("1/fromOneToTwo \(fromOneToTwo)")
var v1 = (fromOneToTwo ? self.view1 : self.view2)
var v2 = (fromOneToTwo ? self.view2 : self.view1)
UIView.transitionFromView(v1, toView: v2, duration: 0.5, options: .TransitionFlipFromLeft | .CurveEaseInOut ) { finished in
self.fromOneToTwo = !self.fromOneToTwo
println("2/fromOneToTwo \(self.fromOneToTwo) ")
}
}
func createView( str:String)->UIImageView!{
var img = UIImage(named: str)!
var imgView = UIImageView(frame: CGRectMake(0, 0, 200, 200))
imgView.image = img
imgView.sizeToFit()
return imgView
}
required init(coder aDecoder:NSCoder){
super.init(coder:aDecoder)
tap = UITapGestureRecognizer(target: self, action: "handleTap:")
view1 = createView("imageOnee.png")
container = UIView(frame: CGRectMake(0, 0, view1.bounds.width, view1.bounds.height))
container.userInteractionEnabled = true
container.addGestureRecognizer(tap)
container.addSubview(view1)
view2 = createView("imageTwo.png")
container.addSubview(view2)
}
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(container)
view.backgroundColor = UIColor.redColor()
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
}
}
I'm having an issue with calling a delegate in my class. I have a SideBarTableController and SideBar.swift file.It was working fine until I logged off and back in. Here is the code. It keeps telling me that 'ViewController' does not conform to protocol 'SideBarDelegate'. I'm new to programming so sorry in advance if this is vague. Anything will help thanks!
import UIKit
import iAd
class ViewController: UIViewController, SideBarDelegate { -----This is where the error is happening
#IBOutlet var menuTab: UIButton! // Menu Tab
#IBOutlet var businessButton: UIButton! // Business Button
#IBOutlet var adBanner: ADBannerView! // Banner Ad
#IBOutlet var imageView: UIImageView! // Main Image in middle
var topHeader: UIImageView! // Utility header
var sideBar:SideBar = SideBar() // Side Bar
override func viewDidLoad() {
super.viewDidLoad()
// Function for menu
// menuTab.addTarget(self, action: "buttonPressed", forControlEvents: UIControlEvents.TouchUpInside)
func menuTab(sender: UIButton){
sideBar = SideBar(sourceView: self.view, menuItems: ["Home", "Business Directory", "Classifieds", "Featured News", "Jobs", "Restaurants", "Sports"])
sideBar.delegate = self }
// Gives the screen dimensions
let screenSize: CGRect = UIScreen.mainScreen().bounds
let screenWidth = screenSize.width
let screenHeight = screenSize.height
// Side bar action and text
sideBar = SideBar(sourceView: self.view, menuItems: ["Home", "Business Directory", "Classifieds", "Featured News", "Jobs", "Restaurants", "Sports"])
sideBar.delegate = self
// Utility Background
var topHeader = UIView(frame: CGRectMake(0, 0, screenWidth, 17))
topHeader.backgroundColor = UIColor(white: 0.0, alpha: 1.0)
self.view.addSubview(topHeader)
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
// Side Bar funcion
func sideBarDidSelectButtonAtIndex(index: Int) {
if index == 0{
imageView.backgroundColor = UIColor.redColor()
imageView.image = nil
} else if index == 1{
imageView.backgroundColor = UIColor.clearColor()
imageView.image = UIImage(named: "image2")
}
}
// Status bar style (white)
override func preferredStatusBarStyle() -> UIStatusBarStyle {
return UIStatusBarStyle.LightContent

}
Here is where I called the SideBarDelegate

sideBarTableViewController.tableView.reloadData()
sideBarContainerView.addSubview(sideBarTableViewController.tableView)
}
func handleSwipe(recognizer:UISwipeGestureRecognizer){

Your SideBarDelegate protocol specifies some methods that must be implemented in order to conform to that protocol. So look at the definition of that protocol, identify what methods are defined therein, and then implement them in your ViewController class.
It's possible you missed one of the functions defined in that protocol, or perhaps you mistyped something in the definition of sideBarDidSelectButtonAtIndex. We cannot say without seeing the definition of this protocol.
Update:
You subsequently supplied the definition of your protocol. It defines two additional functions that you have not implemented in your view controller:
func sideBarWillClose()
func sideBarWillOpen()
You also must implement these two functions in your view controller (even if you put nothing into them).
