I have converted the code for making a phone call from Objective-C to Swift, but in Objective-C, we can set the type of the URL that we like to open (e.g. telephone, SMS, web) like this:
@"tel:xx"
@"mailto:info@example.es"
@"http://stackoverflow.com"
@"sms:768number"
The code in Swift is:
UIApplication.sharedApplication().openURL(NSURL(string : "9809088798")
I read that have not released any scheme parameter for tel:
, but I don't know if Swift can detect if the string is for making a phone call, sending email, or opening a website. Or may I write:
(string : "tel//:9809088798")
?
I am pretty sure you want:
UIApplication.sharedApplication().openURL(NSURL(string: "tel://9809088798")!)
(note that in your question text, you put tel//:
, not tel://
).
NSURL's string init expects a well-formed URL. It will not turn a bunch of numbers into a telephone number. You sometimes see phone-number detection in UIWebView, but that's being done at a higher level than NSURL.
