OpenUrl freezes app for over 10 seconds

Question

I\'m currently developing an App, that needs to open a browser to display a webpage. To do that i use the [UIApplication sharedApplication] openURL method with

Answer 1

After doing some very quick benchmarking I found @lidsinkers method to quite clearly be the fastest. Especially when I replaced the delay of 0.1 with 0.001.

Thus I decided to convert it to Swift code:

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(0.001 * Double(NSEC_PER_SEC))), dispatch_get_main_queue()) {
            UIApplication.sharedApplication().openURL(url)
        }

Full method:

/// An attempt at solving 'openUrl()' freeze problem
func lidsinkerOpenURL(url: NSURL) {
        dispatch_after(dispatch_time(DISPATCH_TIME_NOW, Int64(0.001 * Double(NSEC_PER_SEC))), dispatch_get_main_queue()) {
            UIApplication.sharedApplication().openURL(url)
        }
    }
