If you want to compose a message there you can add more parameters to this URL:

NSString *customURL = @"googlegmail://";

if ([[UIApplication sharedApplication] 
canOpenURL:[NSURL URLWithString:customURL]])
{
  [[UIApplication sharedApplication] openURL:[NSURL URLWithString:customURL]];
}
else
{
  //not installed, show popup for a user or an error
}
