Question

我的UITextView中有一个网址链接。在我的iPhone中，有野生动物园和野生动物园。 chrome应用程序。每当我点击URL链接时，我想列出safari和amp; Chrome（以及手机中的所有其他浏览器）处于弹出视图中，以便用户可以选择要打开网址的浏览器。现在它总是打开safari，因为它是我手机中的默认浏览器。有什么办法可以选择浏览器来打开URL吗？我知道有这个代表

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
        // Got the url here. how can i force this url to open in chrome
        return true
    }

但是如何强制此网址在Chrome或任何其他浏览器中打开？如何在视图中列出所有可用的浏览器？

将其包起来，

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    let actionSheet = UIAlertController(title: "Where do you want to open it", message: "", preferredStyle: .actionSheet)

    if UIApplication.shared.canOpenURL(URL(string: "http://www.stackoverflow.com")!) {
        actionSheet.addAction(UIAlertAction(title: "Safari", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
            UIApplication.shared.open(URL(string: "http://www.stackoverflow.com")!, options: [:], completionHandler: nil)
        }))
    }

    if UIApplication.shared.canOpenURL(URL(string: "googlechrome://www.stackoverflow.com")!) {
        actionSheet.addAction(UIAlertAction(title: "Chrome", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
            UIApplication.shared.open(URL(string: "googlechrome://www.stackoverflow.com")!, options: [:], completionHandler: nil)
        }))
    }

    if UIApplication.shared.canOpenURL(URL(string: "firefox://open-url?url=http://www.stackoverflow.com")!) {
        actionSheet.addAction(UIAlertAction(title: "Fire Fox", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
            UIApplication.shared.open(URL(string: "firefox://open-url?url=http://www.stackoverflow.com")!, options: [:], completionHandler: nil)
        }))
    }

    if UIApplication.shared.canOpenURL(URL(string: "opera-http://www.stackoverflow.com")!) {
        actionSheet.addAction(UIAlertAction(title: "Opera", style: .default, handler: {
            (alert: UIAlertAction!) -> Void in
            UIApplication.shared.open(URL(string: "opera-http://www.stackoverflow.com")!, options: [:], completionHandler: nil)
        }))
    }

    actionSheet.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
    self.present(actionSheet, animated: true, completion: nil)

    return false
}

目前，我无法找到任何用于列出所有浏览器的API。

相反，您可以使用canOpenURL:方法手动检查是否安装了特定应用。

- (BOOL)isSafariInstalled {
    return [[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"http://google.com"]];
}

- (BOOL)isChromeInstalled {
    return [[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"googlechrome://"]];
}

- (BOOL)isOperaInstalled {
    return [[UIApplication sharedApplication] canOpenURL: [NSURL URLWithString:@"opera-http://google.com"]];
}

我没有尝试，只是检查一下。将 false 返回到shouldInteractWith delagte方法。你的东西的委托方法

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
        // Got the url here. how can i force this url to open in chrome

        //here do your stuffs to show popup or something & based on selection launch url with specific browsers

        return false //to restrict open automatically
 }

在UITextView中单击URL时选择浏览器
