推荐答案

您可以使用共享扩展名(UIActivityViewController)共享pdf fileURL.请注意，用户将必须选择WhatsApp应用程序才能共享文件.如果要首先检查是否已安装WhatsApp，则需要注意编辑info.plist并将whatsapp添加到LSApplicationQueriesSchemes阵列中的步骤:

You can use Share Extension (UIActivityViewController) to share your pdf fileURL. Note that the user will have to select the WhatsApp application to share the file. Note is is required to edit your info.plist and add whatsapp to your LSApplicationQueriesSchemes array if you would like to check first if WhatsApp is installed:

func sharePdfWhatsApp(url: URL) {
    let whatsappURL = URL(string:"whatsapp://app")!
    // this will make sure WhatsApp it is installed
    if UIApplication.shared.canOpenURL(whatsappURL) {
        let controller = UIActivityViewController(activityItems: [url], applicationActivities: nil)
        present(controller, animated: true) {
            print("done")
        }
    }
}
