我想创建一个 Nib 并将其附加到我的 View Controller 。为了创建 Nib ，这就是我所做的......
首先，我添加了一个空白 View 并根据需要设计了该 View 。然后我添加了一个 swift 文件并在其中添加了这段代码...
class VerificationCodeView: UIView {
@IBOutlet var contentView: UIView!
@IBOutlet weak var mainLabel: UILabel!
fileprivate weak var view: UIView!
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
commonInit()
}
private func commonInit() {
Bundle.main.loadNibNamed("VerificationCodeView", owner: self, options: nil) //CRASHES HERE
addSubview(contentView)
contentView.frame = self.bounds
contentView.autoresizingMask = [.flexibleHeight, .flexibleWidth]
}
}
然后在 View Controller 的 Storyboard中，我添加了一个空白 View ，并将其设为 VerificationCodeView 类。
在viewcontroller的viewDidLoad中，这就是我调用VerificationCodeView的方法...
@IBOutlet weak var verificationCodeView1: VerificationCodeView! //OUTLET
fileprivate var loadingView: VerificationCodeView?
并在viewDidLoad中，
loadingView = VerificationCodeView(frame: verificationCodeView1.frame)
但是当断点到达 VerificationCodeView 类中的 Bundle.main.loadNibNamed("VerificationCodeView",owner: self, options: nil) 行时，它崩溃了。
我在这里做错了什么......？
编辑1:
这是显示的整个错误日志...

最佳答案
请更新您的函数
private func commonInit() {
let uvNub: UIView = Bundle.main.loadNibNamed("VerificationCodeView", owner: self, options: nil) //CRASHES HERE
self.addSubview(uvNub)
contentView.frame = self.bounds
contentView.autoresizingMask = [.flexibleHeight, .flexibleWidth]
}
关于ios - 将 Nib 加载到 View 时崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/54229518/
