iOS 调用系统短信、邮件发送界面

iOS调用系统发送短信、邮件有两种方法：一种是直接跳到系统的发送功能界面，完成后不能返回到当前界面；第二种是弹出发送界面，完了之后还在停留在当前界面。

方法一：调用系统的接口，如打电话、发短信、邮件、浏览器等，以下这些通常在传递的参数前要加前缀，@"tel://",@"sms://",@"mailto://",@"http://"

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"tel://123456"]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"sms://123456"]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"mailto://[email protected]"]];

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.hao123.com"]]

方法二：是通过调用弹出系统的发送界面，一般通过模态对象实现。

发送短信示例：

-(void)showMessageView : (NSString *)phone title : (NSString *)title body : (NSString *)body
{
    if( [MFMessageComposeViewController canSendText] )
    {
        MFMessageComposeViewController * controller = [[MFMessageComposeViewController alloc] init];
        controller.recipients = [NSArray arrayWithObject:phone];
        controller.body = body;
        controller.messageComposeDelegate = self;
        [self presentModalViewController:controller animated:YES];
        
        [[[[controller viewControllers] lastObject] navigationItem] setTitle:title];//修改短信界面标题
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"提示信息"
                                                        message:@"该设备不支持短信功能"
                                                       delegate:nil
                                              cancelButtonTitle:@"确定"
                                              otherButtonTitles:nil, nil];
        [alert show];
    }
}

-(void)messageComposeViewController:(MFMessageComposeViewController *)controller didFinishWithResult:(MessageComposeResult)result
{

    [self dismissModalViewControllerAnimated:YES];

    switch (result) {
        case MessageComposeResultCancelled:
        {
            //click cancel button
        }
            break;
        case MessageComposeResultFailed:// send failed

            break;
           
        case MessageComposeResultSent:
        {
            //do something
        }
            break;
        default:
            break;
    }

}

发送邮件示则使用 MFMailComposeViewController，具体的google下
