ios - 当用户在我的应用程序中按下联系号码时如何获取电话号码并在电话拨号盘中显示该号码

Question

我有一些以下的 json 数据:

这将全部显示在 map View 中。因此，当用户按下 map 中的任何图钉时。将显示地址、姓名调用按钮。

我有一个 action method 用于那个 call button..所以如果任何用户按下我 map 上的任何图钉。它会显示 Address, name, one call button... 因此，如果用户按下那个调用按钮，它会显示我的 name 和 address 各自或正确的电话号码它应该显示在正常的电话拨号盘中。

我在 objective-c 中做了一些事情。但是我不擅长 swift 2.0。

任何人都可以帮助我如何做到这一点。

    @IBAction func CallButtontap(sender: AnyObject) {

        let phoneUrl: NSURL = NSURL(string: "telprompt:\(item[index]["phone"])")!
        if UIApplication.sharedApplication().canOpenURL(phoneUrl) {
            UIApplication.sharedApplication().openURL(phoneUrl)
        }
    }


    func locationManager(manager: CLLocationManager, didFailWithError error: NSError) {
        print("Error while updating location " + error.localizedDescription)
    }

我试过:

@IBAction func CallButtontap(sender: AnyObject) {

let phoneUrl: NSURL = NSURL(string: "telprompt:\(item[index]["phone"])")!
if UIApplication.sharedApplication().canOpenURL(phoneUrl) {
    UIApplication.sharedApplication().openURL(phoneUrl)
}

没用

最终更新:

func mapView(mapView: MKMapView, didSelectAnnotationView view: MKAnnotationView) {

        print("Inside selecting annotation")

       LocationView.hidden = false

        if let newTitle = view.annotation?.title, let newAddress = view.annotation?.subtitle, let AddressNewImage = view.detailCalloutAccessoryView {

            AddressTitleLabel.text = newTitle

            AddressSubtitleLabel.text = newAddress

            //setting callout accessory as image to UIImage
            UIGraphicsBeginImageContextWithOptions(view.bounds.size, view.opaque, 0);

            AddressNewImage.drawViewHierarchyInRect(view.bounds, afterScreenUpdates: true)

            let NAimage:UIImage = UIGraphicsGetImageFromCurrentImageContext();

            AddressImg.image = NAimage
            if (view.annotation is Annotation.self) {
                var annot: Annotation = view.annotation
                var index: Int = self.arrayOfAnnotations.indexOfObject(annot)
                CallButtontap(index)
            }

        }


    }

@IBAction func CallButtontap(sender: AnyObject) {

let phoneUrl: NSURL = NSURL(string: "telprompt:\(item[sender]["phone"])")!
if UIApplication.sharedApplication().canOpenURL(phoneUrl) {
    UIApplication.sharedApplication().openURL(phoneUrl)
}

这是您的代码的快速版本:

@IBAction func didTapPhoneButton(sender: UIButton) {
    // This function  will make phone call 
    let phoneUrl: NSURL = NSURL(string: "telprompt:\(myJson[index]["phone"])")!
    if UIApplication.sharedApplication().canOpenURL(phoneUrl) {
        UIApplication.sharedApplication().openURL(phoneUrl)
    } else {
        PCUtilities.showAlertWithTitle("Alert", message: "Call facility is not available!!!", cancelButtonTitle: "OK")
    }
}
