使用 swiftUI 文本字段和 WKWebView 文本字段时应用程序崩溃
App crashes when using a swiftUI textfield and a WKWebView textfield
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(运行 in XCode 13.2.1)
重现崩溃:
- 在 mac(最好是 M1)
上启动应用程序
- 单击文本字段
- 单击 google 搜索栏
- 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以及我该如何解决?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:

我不确定这里的违规者是什么,可能是 MacCatalyst 本身,但答案实际上是在文本字段上禁用自动更正。
原因是因为 运行 MacCatalyst 应用程序假设有一个带有 TextField 的虚拟键盘,因此此类错误经常出现在生产代码中。由于某种原因,这会导致 M1 设备崩溃。禁用预测文本是解决此问题的方法。这是代码:
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)
)
.disableAutoCorrection(true)
}
}
}
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)
