你可以利用这个:

- (void)launchMailAppOnDevice
{
    NSMutableString *subject  = [NSMutableString string];
    [subject appendString:@"Your Subject"];

    NSMutableString *mailbody  = [NSMutableString string];
    [mailbody appendString:@"Blah Blah Blah"];
    [mailbody appendString:@"Blah Blah Blah "];

    NSString *recipients = [NSString stringWithFormat:@"mailto:test@test.com?&subject=%@!",subject];

    NSString *body = [NSString stringWithFormat:@"&body=%@!",mailbody];;

    NSString *emailString = [NSString stringWithFormat:@"%@%@", recipients, body];

    emailString = [emailString stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

    [[UIApplication sharedApplication] openURL:[NSURL URLWithString:email]];
}

如果你想检查邮件应用程序是否存在并且你想打开它。

if ([[UIApplication sharedApplication] canOpenURL:[ NSURL URLWithString:@"mailto:"]]) 
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto:"]];
