我试图拨打不使用特定号码的号码,而是拨打变量中的号码,或至少告诉它拨打手机中的号码。在变量中调用的这个数字是我使用解析器或从网站sql中获取的数字。我做了一个按钮试图通过功能调用存储在变量中的电话号码,但无济于事。什么都有帮助谢谢!
func callSellerPressed (sender: UIButton!){
//(This is calls a specific number)UIApplication.sharedApplication().openURL(NSURL(string: "tel://######")!)
// This is the code I'm using but its not working
UIApplication.sharedApplication().openURL(NSURL(scheme: NSString(), host: "tel://", path: busPhone)!)
}
答案 0 :(得分:160)
试试吧:
if let url = NSURL(string: "tel://\(busPhone)") where UIApplication.sharedApplication().canOpenURL(url) {
UIApplication.sharedApplication().openURL(url)
}
假设电话号码在busPhone
。
NSURL
' init(string:)
返回一个可选项,因此我们使用if let
确保url
为NSURL
(而不是NSURL?
init
返回的if let url = URL(string: "tel://\(busPhone)"), UIApplication.shared.canOpenURL(url) {
if #available(iOS 10, *) {
UIApplication.shared.open(url)
} else {
UIApplication.shared.openURL(url)
}
}
。

我们需要检查我们是否在iOS 10或更高版本上,因为:
'的OpenURL'在iOS 10.0中已弃用

iOS 10中的自包含解决方案, Swift 3 :
private func callNumber(phoneNumber:String) {
if let phoneCallURL = URL(string: "tel://\(phoneNumber)") {
let application:UIApplication = UIApplication.shared
if (application.canOpenURL(phoneCallURL)) {
application.open(phoneCallURL, options: [:], completionHandler: nil)
}
}
}
您应该可以使用callNumber("7178881234")
拨打电话。

好的,我得到了帮助并想出来了。此外,我还放了一个漂亮的小警报系统,以防电话号码无效。我的问题是我说的是正确的,但数字有空格和不需要的字符,如(“123 456-7890”)。如果您的号码是(“1234567890”),则UIApplication仅适用或接受。因此,您基本上通过创建一个新变量来仅删除数字来删除空格和无效字符。然后使用UIApplication调用这些数字。
func callSellerPressed (sender: UIButton!){
var newPhone = ""
for (var i = 0; i < countElements(busPhone); i++){
var current:Int = i
switch (busPhone[i]){
case "0","1","2","3","4","5","6","7","8","9" : newPhone = newPhone + String(busPhone[i])
default : println("Removed invalid character.")
}
}
if (busPhone.utf16Count > 1){
UIApplication.sharedApplication().openURL(NSURL(string: "tel://" + newPhone)!)
}
else{
let alert = UIAlertView()
alert.title = "Sorry!"
alert.message = "Phone number is not available for this business"
alert.addButtonWithTitle("Ok")
alert.show()
}
