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

Swift 5 version:

if let mailURL = URL(string: "message:") {
    if UIApplication.shared.canOpenURL(mailURL) {
        UIApplication.shared.open(mailURL, options: [:], completionHandler: nil)
    }
}
