在UITextView中點擊網址時選擇瀏覽器

Question

我在我的UITextView中有一個URL鏈接。而在我的iPhone中，有兩個Safari瀏覽器& Chrome應用程序。每當我點擊URL鏈接時，我想在彈出視圖中列出Safari瀏覽器& Chrome（以及手機中的所有其他瀏覽器），以便用戶可以選擇想要打開該URL的瀏覽器。現在它總是打開safari，因爲它是我手機中的默認瀏覽器。有什麼辦法可以選擇瀏覽器來打開網址嗎？我知道有這個代表

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 
    } 

但我怎麼能強制此網址在鉻或任何其他瀏覽器打開？我怎樣才能在視圖中列出所有可用的瀏覽器？

要包裝它，

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 
}

目前我找不到列出所有瀏覽器的任何API。

您可以使用canOpenURL:方法手動檢查特定應用程序是否已安裝。

- (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"]]; 
}

我沒試過，只是檢查，它out.Return 假到shouldInteractWith delagte method.You此委託方法爲你的東西

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 
}
