swift - 使用 swiftUI 文本字段和 WKWebView 文本字段时应用程序崩溃

Question

我目前有一个应用程序在网站的文本字段(比方说搜索框)上方使用 SwiftUI 文本字段。该应用程序不会在 iOS 或 iPadOS 中崩溃。

但是，在 M1 mac 上的 MacCatalyst 中，当我单击 SwiftUI 文本字段然后单击网站上的搜索栏时，应用程序立即崩溃。

我创建了一个可重现的示例，附在下面(在 XCode 13.2.1 中运行)

重现崩溃:

1. 在 Mac(最好是 M1)上启动应用
2. 点击文本框
3. 点击谷歌搜索栏
4. 应该发生崩溃

在 Rosetta 上运行时，日志中也会发生崩溃，但应用程序不会终止。

有谁知道问题出在哪里，我该如何解决？提前谢谢你。

import SwiftUI
import WebKit

struct ContentView: View {
  @State var textObject: String = ""
   
  var body: some View {
    ZStack {
      WebView(url: URL(string: "https://google.com")!)

      TextField("", text: $textObject)
        .background(
          Rectangle()
            .foregroundColor(.black)
        )
    }
  }
}

struct WebView: UIViewRepresentable {   
  var url: URL
 
  func makeUIView(context: Context) -> WKWebView {
    return WKWebView()
  }
 
  func updateUIView(_ webView: WKWebView, context: Context) {
    let request = URLRequest(url: url)
    webView.load(request)
  }
}

这是来自 XCode 的错误消息: libc++abi: terminating with uncaught exception of type NSException *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid parameter not satisfying: <SPRoundedWindow: 0x126774250>.

Answer 1

我在使用 maccatalyst 的 WKWebView 时也遇到了同样的崩溃。在尝试了不同的解决方案后，我终于添加了这段代码来修复我的崩溃。

    typealias winClosureType =  @convention(c) (Any, Selector) -> UITextAutocorrectionType
static func swizzleInputTraits() {
    guard let textInputTraits: AnyClass = NSClassFromString("UITextInputTraits") else { return }
    let sel_AutocorrectionType: Selector = sel_getUid("autocorrectionType")
    
    if let method = class_getInstanceMethod(textInputTraits, sel_AutocorrectionType) {
        let originalImp: IMP = method_getImplementation(method)
        let original: winClosureType = unsafeBitCast(originalImp, to: winClosureType.self)

        let block : @convention(block) (Any) -> UITextAutocorrectionType = { (textInputTraits) in
            let obj = original(textInputTraits, sel_AutocorrectionType)
            
            return obj == .default ? .no : obj
        }
        let imp: IMP = imp_implementationWithBlock(block)
        method_setImplementation(method, imp)
    }
}

我在这里调整 UITextInputTraits 的 autocorrectionType 属性。我默认禁用所有文本字段的自动更正类型。如果任何文本字段需要，我们必须显式启用 autocorrectionType 属性。

我们可以把这个函数放在 AppDelegate 类中，然后像这样从这个委托(delegate)函数中调用它。

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool
{
AppDelegate.swizzleInputTraits()
}
