如果用户拒绝访问摄像头,如何防止WKWebView显示摄像头模式?

因为你提到 __CRASHING_DUE_TO_PRIVACY_VIOLATION__

尝试添加密钥的描述 NSMicrophoneUsageDescription Info.plist Privacy - Microphone Usage Description

other answer 将为您提供各种隐私密钥及其描述的更多详细信息。

这似乎是一个错误,因为它只有在选择视频时才会崩溃。我通过注入JS找到了一个解决方法:

• 将内容类型设置为仅允许照片。(下面包含示例代码)
• 禁用输入文件

func requestCamera() {
    AVCaptureDevice.requestAccess(forMediaType: AVMediaTypeVideo) { response in
        if response {
            self.injectJavascript()
        } else {
            self.webView = WKWebView(frame: .zero)
        }


        self.setupRequest()
    }
}

func injectJavascript() {
    let webConfiguration = WKWebViewConfiguration()
    let contentController = WKUserContentController()
    let js = "var fileInput = document.getElementById('allMedia'); fileInput.setAttribute('accept', 'image/*');"
    let userScript = WKUserScript(source: js, injectionTime: WKUserScriptInjectionTime.atDocumentEnd, forMainFrameOnly: false)
    contentController.addUserScript(userScript)
    webConfiguration.userContentController = contentController
    webView = WKWebView(frame: .zero, configuration: webConfiguration)
}

func setupRequest() {
    let url = URL(string: "...")!
    let request = URLRequest(url: url)
    webView.load(request)
}

1. 允许摄像头访问?
   • 对
     1. 正常加载WKWebView
   • 不
     2. 设置WKWebView
