ios - 调用中的参数标签不正确(有 'frame:' ，预期为 'coder:' )

Question

它在 UIView 中工作但在 ViewController 中不工作，我收到此错误“调用中的参数标签不正确(有'frame:'，预期'coder:')”，如何解决这个问题。请查看附件图片

 init(frame: CGRect) {
    super.init(frame: frame)
    self.view.backgroundColor=UIColor.clear

    currentMonthIndex = Calendar.current.component(.month, from: Date()) - 1
    currentYear = Calendar.current.component(.year, from: Date())
    setupViews()
    btnLeft.isEnabled=true
}

super.init(frame: frame) 我收到这一行的错误

Answer 1

UIViewController 不包含框架初始化它仅用于 UIView 元素

let myViewController = MyViewController( )

或

let myViewController = MyViewController(nibName: "MyViewController", bundle: nil)

//

class myViewController:UIViewController {

  // put here the properties 

    override func viewDidLoad() {
       super.viewDidLoad()
       self.view.backgroundColor=UIColor.clear
       currentMonthIndex = Calendar.current.component(.month, from: Date()) - 1
       currentYear = Calendar.current.component(.year, from: Date())
       setupViews()
       btnLeft.isEnabled=true
  }
}
