Create Custom UIView and Use in ViewController / 사용자 커스텀 뷰 (닙생성) 만들고 뷰컨트롤러에서 불러쓰기

 

1. 아무거나 사용자 닙 하나 만듬. / Create custom uiview.xib

 

2. MyView.swift 를 아래와 같이 만들어줌. / Create MyView.swift and Type code below.....and focus on nib file name.

I had a wrong xib name... I wanted "MyView.xib", but wrote "MtView.xib"..

So, I faced crash app.....

import UIKit   class MyView: UIView {     @IBOutlet var main_view: UIView!          @IBOutlet weak var text_label: UILabel!     override init(frame: CGRect) {         super.init(frame: frame)             }          required init?(coder aDecoder: NSCoder) {         super.init(coder: aDecoder)                  customInit()     }         func customInit() {         if let view = Bundle.main.loadNibNamed("MtView", owner: self, options: nil)?.first as? UIView {             view.frame = self.bounds             self.addSubview(view)         }     }     /*     // Only override draw() if you perform custom drawing.     // An empty implementation adversely affects performance during animation.     override func draw(_ rect: CGRect) {         // Drawing code     }     */   }

 

3. 원하는 뷰 컨트로러에 붙임. / Add UIView and set constrains..

 

4. 뷰컨트롤러에서 저래 불러쓰믄 뎀 / Call MyView(custom view) as below...

import UIKit   class ViewController: UIViewController {       @IBOutlet weak var my_view: MyView!     override func viewDidLoad() {         super.viewDidLoad()         // Do any additional setup after loading the view.                  print("viewDidLoad")         //addCustomView()     }       /*     func addCustomView() {         if let customView = Bundle.main.loadNibNamed("MyView", owner: nil, options: nil)?.first as? UIView {             customView.frame = self.view.bounds             my_view.addSubview(customView)         }     }     */ }

 

End.
