Link a UIView subclass to xib file - ios

Question

I've created a UIView subclass, which i want to link to a xib file. I've added a xib file and set the class to DraggableView, however when i for instance create a lable and link it to the information. it returns that information is equal to nil? why doesnt it work?
class DraggableView: UIView {
var delegate: DraggableViewDelegate!
#IBOutlet var information: UILabel!
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
}
override init(frame: CGRect) {
super.init(frame: frame)
information.text = "no info given"
information.textAlignment = NSTextAlignment.Center
information.textColor = UIColor.blackColor()
self.backgroundColor = UIColor.whiteColor()
}
}

Answer 1

Please ensure you add init from XIB method in your custom UIView like this:
class func instanceFromNib() -> UIView {
return UINib(nibName: "nib file name", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as UIView
}
And then you can use it like this:
var view = DraggableView.instanceFromNib()
view.information.text = "Test Label"
self.view.addSubview(view)

Answer 2

You need for your custom UIView to load XIB file first before setting objects value.
class DraggableView: UIView {
var delegate: DraggableViewDelegate!
#IBOutlet var information: UILabel!
init() { xibSetup() }
override init(frame: CGRect) {
super.init(frame: frame)
xibSetup()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
if self.subviews.count == 0 {
xibSetup()
}
}
func xibSetup() {
let view = loadViewFromNib()
view.frame = bounds
view.autoresizingMask = [UIViewAutoresizing.FlexibleWidth, UIViewAutoresizing.FlexibleHeight]
addSubview(view)
// INIT THERE YOUR LABEL
information.text = "no info given"
information.textAlignment = NSTextAlignment.Center
information.textColor = UIColor.blackColor()
self.backgroundColor = UIColor.whiteColor()
}
func loadViewFromNib() -> UIView {
let bundle = NSBundle(forClass: self.dynamicType)
let nib = UINib(nibName: "nib file name", bundle: bundle)
let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView
return view
}
and call simplely like that :
var view = DraggableView()
