如何在不离开应用程序的情况下在应用程序中发送电子邮件.

这有效:

-(void) sendEmailTo:(NSString *)to withSubject:(NSString *)subject withBody:(NSString *)body {
NSString *mailString = [NSString stringWithFormat:@"mailto:?to=%@&subject=%@&body=%@",
                        [to stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
                        [subject stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding],
                        [body stringByAddingPercentEscapesUsingEncoding:NSASCIIStringEncoding]];
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:mailString]];
}

但去邮件应用程序发送.有没有办法在不离开应用程序的情况下执行此操作？
