Launch Apple Mail App from within my own App?

Question

What I already found is

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@\"mailto:\"]];

But I just want to open the Mail ap

Answer 1

It will open Default Mail App with composer view:

NSURL* mailURL = [NSURL URLWithString:@"mailto://"];
if ([[UIApplication sharedApplication] canOpenURL:mailURL]) {
    [[UIApplication sharedApplication] openURL:mailURL];
}

It will open Default Mail App:

NSURL* mailURL = [NSURL URLWithString:@"message://"];
if ([[UIApplication sharedApplication] canOpenURL:mailURL]) {
    [[UIApplication sharedApplication] openURL:mailURL];
}
