如何使用Swift 2从Xib加载自定义UIView？

Question

The task is to create custom UIView that loads UI from .xib file using Swift. How do I do that?

I tried to do that using the code:

import UIKit

@IBDesignable class CustomView: UIView {

var view: UIView!

@IBOutlet weak var label: UILabel!

override init(frame: CGRect) {
    super.init(frame: frame)
    xibSetup()
}

required init?(coder aDecoder: NSCoder) {
    super.init(coder: aDecoder)
    xibSetup()
}

func xibSetup() {
    view = loadViewFromNib()
    view.frame = bounds
    view.autoresizingMask = [UIViewAutoresizing.FlexibleWidth, UIViewAutoresizing.FlexibleHeight]

    addSubview(view)
}

func loadViewFromNib() -> UIView {
    let bundle = NSBundle(forClass: self.dynamicType)
    let nib = UINib(nibName: "CustomView", bundle: bundle)
    let view = nib.instantiateWithOwner(self, options: nil)[0] as! UIView

    return view
}

}

It runs, but crashes with EXC_BAD_ACCESS and shows me the message:

warning: could not load any Objective-C class information. This will significantly reduce the quality of type information available.

Actually, I need to translate code given here http://qnoid.com/2013/03/20/How-to-implement-a-reusable-UIView.html to Swift 2.0, but I have no idea how to do this.

Answer 1

Try

let yourView = NSBundle.mainBundle().loadNibNamed("youViewNibName", owner: self, options: nil).first as! YourView

Do it in your ViewController class , then you can access the view in required init with coder, where you should call xibSetup() .

Answer 2

Is it correct, that your class is called CustomView and you're loading CustomView.xib where the class for the view in xib is CustomView ?

If that is so you probably do not understand what you're doing
