在找到问题 2 的解决方案后（并且给人的印象是问题 1 没有简单的、开箱即用的解决方案），我决定关闭这个问题，而专门针对分页问题创建另一个问题。
我有两个问题WKWebViews createPDF(configuration:completionHandler:):
下面的代码...
import SwiftUI
import WebKit
@main
struct PdfCreatorSOApp: App {
var body: some Scene {
WindowGroup {
ContentView()
}
}
}
struct ContentView: View {
var body: some View {
Button("Create PDF") {
savePdf()
}
.padding()
}
private func savePdf() {
if let downloadDir = FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask).first {
let savePath = downloadDir.appendingPathComponent("swiftPdf").appendingPathExtension("pdf")
let webViewConfiguration = WKWebViewConfiguration()//do I need to set s.th. here?
let webView = WKWebView(frame: .zero, configuration: webViewConfiguration)
let pdfConfiguration = WKPDFConfiguration()
pdfConfiguration.rect = CGRect(x: 0, y: 0, width: 595.28, height: 841.89)
webView.loadHTMLString(html, baseURL: nil)
DispatchQueue.main.asyncAfter(deadline: .now() + 0.1) {
webView.createPDF(configuration: pdfConfiguration) { result in
switch result {
case .success(let data):
do {
try data.write(to: savePath)
print("Successfully created and saved pdf…")
} catch let error {
print("Could not _save_ pdf: \(error)")
}
case .failure(let error):
print("Could not create pdf: \(error)")
}
}
}
}
}
}
let html = """
<html>
<body>

…produces this output:
我的身上是否缺少了什么WKWebViewConfiguration()?
EDITED:
这只是一个猜测，但我不认为它用换行符替换空格。它尽可能窄地包装它认为狭窄的网页（每个单词）。
尝试调整 webView 的框架大小，看看是否有帮助？
let webView = WKWebView(frame: .zero,... // per comments this didn't help.
或者尝试通过CSS调整网页的大小：
<p> <div **style='width: 600'**> lorem.... </div> // per comments this did
