ios - SFSafariViewController crash: The specified URL has an unsupported scheme. -


my code:

if let url = nsurl(string: "www.google.com") {     let safariviewcontroller = sfsafariviewcontroller(url: url)     safariviewcontroller.view.tintcolor = uicolor.wantoprimaryorangecolor()     presentviewcontroller(safariviewcontroller, animated: true, completion: nil) }

this crashes on initialization exception:

the specified url has unsupported scheme. http , https urls supported

when use url = nsurl(string: "http://www.google.com"), fine. loading url's api , hence, can't sure prefixed http(s)://.

how tackle problem? should check , prefix http:// always, or there's workaround?

you can check availability of http in url string before creating nsurl object.

put following code before code , solve problem (you can check https in same way)

var strurl : string = "www.google.com" if strurl.lowercasestring.hasprefix("http://")==false{      strurl = "http://".stringbyappendingstring(strurl) }

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
