I have this code
import UIKit
class CardView: UIView {
@IBOutlet var imageView: UIImageView!
init(imageView: UIImageView) {
self.imageView = imageView
super.init(frame: CGRect(x: 0, y:0, width: self.frame.size.width, height: self.frame.size.height))
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
I get an error at the line:
super.init(frame: CGRect(x: 0, y:0, width: self.frame.size.width, height: self.frame.size.height))
The error says Use of 'self' in property access 'frame' before super.init initializes self
I don't have any idea how to solve this.
Please bare in mind I am from an objective - C background and recently started learning swift.
You must call super.init()
before accessing self
within a init()
method:
init(imageView: UIImageView) {
self.imageView = imageView /*you are accessing self here before calling super init*/
super.init(frame: CGRect(x: 0, y:0, width: self.frame.size.width /* here also*/, height: self.frame.size.height))
}
Change it to:
init(imageView: UIImageView) {
super.init(frame: CGRect(origin: CGPoint.zero, size: imageView.frame.size))
self.imageView = imageView
}
