Question

我遇到了今天困扰着任何Apple开发人员的错误代码EXC_BAD_ACCESS ..经过大量的研究，以各种不同的调试方法等，我来到了这里。

更新：如果有人愿意帮助解决此问题，https://github.com/TheRiseCollection/sway

是这里的GitHub库链接。

在Xcode中打开zombie objects告诉我nil处的guard let view = nib.instantiate(withOwner: self, options: nil).first as? T引起了我的问题Thread 1: EXC_BAD_ACCESS (code=2, address=0x7ffeec121e98)

下面是完整文件NibView.swift

//Joshua Paulsen - The Rise Collection



import UIKit

/// A base UIView subclass that instaniates a view
/// from a nib file of the same class name in order to
/// allow reusable views to be created.
internal protocol NibView where Self: UIView {

}

extension NibView {

    /// Initializes the view from a xib
    /// file and configure initial constrains.
    func xibSetup() {
        backgroundColor = .clear
        let view = loadViewFromNib()
        addEdgeConstrainedSubView(view: view)
    }

    /// Loads a view from it's xib file.
    ///
    /// - Returns: an instantiated view from the Nib file of the same class name.
    fileprivate func loadViewFromNib<T: UIView>() -> T {
        let bundle = Bundle(for: type(of: self))
        let nib = UINib(nibName: String(describing: type(of: self)), bundle: bundle)
        guard let view = nib.instantiate(withOwner: self, options: nil).first as? T else {
            fatalError("Cannot instantiate a UIView from the nib for class \(type(of: self))")
        }
        return view
    }

}

我刚开始接触笔尖视图！在此处寻求解决方案，我们将不胜感激。

Answer 1

具有自定义类，已将其分配给我所拥有的每个视图，从而导致此EXC_BAD_ACCESS错误触发。

删除它们使它停止了。让我们继续解决这个臭名昭著的EXC_BAD_ACCESS错误。谢谢大家的帮助。

Answer 2

EXC_BAD_ACCESS错误的另一个原因是在NSNotificationCenter中从收到通知时调用的函数发送通知。
