I'm pretty sure there must be a way to launch spotify iphone app from my own app. I've seen SMP app (share my playlist) doing something very similar when pushing playlist into spotify app.
I guess it should be by using something like:
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"spotify://search:muse"]];
As you can see, I want to be able to make spotify search for a specific keyword. The problem is I don't really know the spotify url scheme, if there is such thing available.
I've been searching in the web, in spotify developer website, etc. but nothing comes up...
