如何使用Swift在iOS 10中拨打电话？ [英] How to make phone call in iOS 10 using Swift?

问题描述

我希望我的应用能够在点击按钮时拨打特定号码。我试过谷歌但是到目前为止似乎没有iOS 10（openURL已经消失了）。有人能为我举一个如何做的例子吗？例如：

I want my app to be able to call a certain number when a button is clicked. I've tried to google it but there doesn't seem to have one for iOS 10 so far (where openURL is gone). Can someone put an example for me on how to do so? For instance like:

@IBAction func callPoliceButton(_ sender: UIButton) {
    // Call the local Police department
}

推荐答案

你可以像这样打电话：

You can call like this:

 if let url = URL(string: "tel://\(number)") {
                UIApplication.shared.openURL(url)
            }

Swift 3 + ，你可以使用

guard let number = URL(string: "tel://" + number) else { return }
UIApplication.shared.open(number)

OR

UIApplication.shared.open(number, options: [:], completionHandler: nil)

确保您已清除电话号码字符串以删除的任何实例（ ，）， - 或 space 。

Make sure you've scrubbed your phone number string to remove any instances of (, ), -, or space.
