Question

我的代码是：

import UIKit

class RCSubscriptionPackageView: UIView {

let centeredCollectionViewFlowLayout = CenteredCollectionViewFlowLayout()
let collectionView :UICollectionView
let cellPerWidth = 0.7

let container: UIView!

override init(nibName nibNameOrNil: String?, bundle nibBundleOrNil: Bundle?) {
    collectionView = UICollectionView(centeredCollectionViewFlowLayout: centeredCollectionViewFlowLayout)
    super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)
}

错误在上面的初始化程序

中

override init(frame: CGRect) {
    super.init(frame: frame)
    self.backgroundColor = .lightGray
    collectionView.backgroundColor = .clear

    centeredCollectionViewFlowLayout.itemSize = CGSize(
        width: self.bounds.width * CGFloat(cellPerWidth),
        height: self.bounds.height * CGFloat(cellPerWidth) * CGFloat(cellPerWidth)
    )
    centeredCollectionViewFlowLayout.minimumLineSpacing = 20
    collectionView.showsVerticalScrollIndicator = false
    collectionView.showsHorizontalScrollIndicator = true

    addContainerView()
    addConstraintsForContainer()
    collectionView.register(
        RCSubscriptionPackCollectionViewCell.self,
        forCellWithReuseIdentifier: String(describing: RCSubscriptionPackCollectionViewCell.self)
    )


    centeredCollectionViewFlowLayout.minimumLineSpacing = 20
    collectionView.showsVerticalScrollIndicator = false
    collectionView.showsHorizontalScrollIndicator = true



}

required init?(coder aDecoder: NSCoder) {
    fatalError("init(coder:) has not been implemented")
}

func addContainerView() -> Void {

    container.backgroundColor = .lightGray
    container.translatesAutoresizingMaskIntoConstraints = false
    container.addSubview(collectionView)

}

func addConstraintsForContainer() -> Void {
    container.snp.makeConstraints { (make) in
        make.edges.equalToSuperview()
    }
}


}

错误表示＆＃39;初始化程序不会覆盖超类中的指定初始化程序＆＃39;

并在

 super.init(nibName: nibNameOrNil, bundle: nibBundleOrNil)

错误是＆＃39;无法调用＆＃39; UIView.init＆＃39;使用类型＆＃39;的参数列表（nibName：String ?, bundle：Bundle？）＆＃39;

我在每个地方都搜索过它，但没有得到任何东西。请让我离开这个。

Answer 1

UIView支持这两个初始化程序

init(frame: CGRect)
init?(coder aDecoder: NSCoder)

init(nibName:bundle:属于视图控制器或NIB

无法调用＆＃39; UIView.init＆＃39;使用类型＆＃39;的参数列表（nibName：String ?, bundle：Bundle？）＆＃39;
