Hi,
I'm a little confused here. I have a UIButton encased inside a MenuItemView, which is inside an ExerciseMenuView. The UIButton isn't outside the MenuItemView's frame, and userInteractionEnabled on the button is set to "true". Yet, I don't know why I can't touch the button.
Edit: I didn't use an XIB here. I had an XIB for my MenuItemView's superview, which worked for a while before something decided to mess up the app.
MenuItemView's code:
/
/
/
/
/
/
/
import UIKit
enum ActivityStatus {
case NotThereYet
case Next
case Completed
}
class MenuItemView: UIView {
var currentStatus : ActivityStatus = ActivityStatus.NotThereYet
var starNum : Int = 1
let button: UIButton! = UIButton()
@IBOutlet var starImageView: UIImageView! {
didSet {
/
let mainBundle = Bundle(for: MenuItemView.self)
let starURL = mainBundle.path(forResource: "\(starNum)star", ofType: "png", inDirectory:"pictures")
let starImage = UIImage(contentsOfFile: starURL!)
starImageView!.image = starImage!
button.bringSubview(toFront: button)
/
self.starImageView!.isHidden = true
/
self.starImageView!.contentMode = UIViewContentMode.scaleAspectFit
}
}/* Star image view. Defined in storyboard **/
func buttonPressed() {
(superview as! ExerciseMenuView).buttonPressed(sender: self)
}
init(frame: CGRect,_tag: Int)
{
super.init(frame: frame)
tag = _tag;
starImageView = UIImageView(frame: bounds)
addSubview(starImageView!)
addPlayButton()
}
func addPlayButton() /
{
/
self.addSubview(button)
/
let mainBundle = Bundle(for: MenuItemView.self)
let playURL = mainBundle.path(forResource: "play-button", ofType: "png", inDirectory:"pictures")
let playImage = UIImage(contentsOfFile: playURL!)
button.setBackgroundImage(playImage, for: UIControlState.normal)
button.isUserInteractionEnabled = false
/
button.addTarget(self, action: #selector(MenuItemView.buttonPressed), for: UIControlEvents.touchUpInside)
/
button.translatesAutoresizingMaskIntoConstraints = true
/
let buttonOrigin = CGPoint(x:0, y:bounds.maxY)
let buttonSize = CGSize(width: bounds.size.width, height: 128)
button.frame = CGRect(origin: buttonOrigin, size: buttonSize)
/
button.contentMode = UIViewContentMode.scaleAspectFit
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
addPlayButton()
}
override init(frame: CGRect)
{
super.init(frame: frame)
}
func setActivityStatus(newStatus : ActivityStatus) {
self.isHidden = false
currentStatus = newStatus
switch newStatus {
case .Next:
button.isHidden = false
button.isUserInteractionEnabled = true
case .Completed:
starImageView!.isHidden = false
button.isUserInteractionEnabled = false
button.isHidden = true
default:
button.isHidden = true
starImageView!.isHidden = true
break
}
/
if (self.tag == 2)
{
print("setActivityStatus: Star image view superview is \(String(describing: starImageView?.superview))")
}
}

override func drawRect(rect: CGRect) {
