My code:
if let url = NSURL(string: "www.google.com") {
let safariViewController = SFSafariViewController(URL: url)
safariViewController.view.tintColor = UIColor.primaryOrangeColor()
presentViewController(safariViewController, animated: true, completion: nil)
}
This crashes on initialization only with exception:
The specified URL has an unsupported scheme. Only HTTP and HTTPS URLs are supported
When I use url = NSURL(string: "http://www.google.com")
, everything is fine.
I am actually loading URL's from API and hence, I can't be sure that they will be prefixed with http(s)://
.
How to tackle this problem? Should I check and prefix http://
always, or there's a workaround?
You can check for availability of http in your url
string before creating NSUrl
object.
Put following code before your code and it will solve your problem (you can check for https
also in same way)
var strUrl : String = "www.google.com"
if strUrl.lowercaseString.hasPrefix("http://")==false{
strUrl = "http://".stringByAppendingString(strUrl)
}
