iOS发送短信

iPhone开发中，发送短信方法有二：

1。URL Scheme，这样不可以设置短信内容

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms：//10086"]];
//打电话可以这样
//[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel：//10086"]]; 

2。MFMessageComposeViewController，这样可以设置短信的内容

MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease];
        if ([MFMessageComposeViewController canSendText])        {
            if (![self.friendLabel.text isEqualToString:@"{好友}"])
                controller.recipients = [NSArray arrayWithObjects:self.friendLabel.text, nil];
                controller.body = self.shareMessageTextView.text;
                controller.messageComposeDelegate = self;
                [self presentModalViewController:controller animated:YES];
        }
