OpenUrl freezes app for over 10 seconds

openurl

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 an url.

In iOS 6 this works perfectly, but in iOS 7 it freezes the app for 10+ seconds, then opens the browser and all is good.

This happens using ad hoc provisioning. Someone on the internet commented that this was a known problem, however, that one comment was all i could find regarding this problem.

I noticed the same problem when calling -[UIApplication openUrl:] from the Application Delegate didReceiveRemoteNotification: or didFinishLaunchingWithOptions: since iOS 7.

I solved it by delaying the call a bit using GCD :

// objc dispatch_async(dispatch_get_main_queue(), ^{     [[UIApplication sharedApplication] openURL:url]; }); 

It let iOS some time to finish application initialization and the call is then performed without any problem. Don't ask me why.

Does this works for you ?

As this answer is often seen, I added the swift version:

// swift dispatch_async(dispatch_get_main_queue()) {     UIApplication.sharedApplication().openURL(url) }
