Launch Podcast App With URL scheme

I'm trying to open the podcast app with a url like this

- (void)setupPodcast
{
    NSLog(@"setup podcast");
    NSString *str = [NSString stringWithFormat:@"pcast://podcasts.sdxme.org/RSS/default.aspx?ID=%ld", (long)[[NSUserDefaults standardUserDefaults] integerForKey:@"CustomerID"]];
    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:str]];
}

2015-10-18 23:45:11.367 [29302:1691034] LaunchServices: ERROR: There is no registered handler for URL scheme pcast

However it looks like the pcast scheme is no longer supported? How can I open my own XML feed in the podcast app?

Solution

I believe Apple changed their recognized podcast scheme and you should now use 'feed://...'.
