How to check for custom url scheme on iphone?

问题

I want to use custom url schemes in my app, for example calling navigons mobile navigator. First of all I want to check whether navigon is installed or at least whether the custom url scheme "navigon://" has already been registered.

Any Ideas?

Thanks a lot.

Have a look at UIApplication's

- (BOOL)canOpenURL:(NSURL *)url
