通过短信发送当前位置

Question

我试图让我的应用能够通过短信将其当前GPS位置发送至预先输入的电话号码。

我现在有我的代码，只能在应用程序中调出一个短信窗口，在该窗口中我可以在接收号码和主体中编辑。我想知道的是我如何获得这个机构的当前位置，以便通过短信发送？无法弄清楚。

这就是我的代码现在看起来关于SMS功能的方式。

-(IBAction) sendInAppSMS:(id) sender 
{ 
    MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease]; 
    if([MFMessageComposeViewController canSendText]) 
    { 
     controller.body = @"Alarm!, call the senders number!"; 
     controller.recipients = [NSArray arrayWithObjects:@"phonenumber1", @"phonenumber2", nil]; 
     [self presentModalViewController:controller animated:YES]; 
    } 
}

首先在您的项目中添加核心位置框架。并调用此方法来查找当前位置。

-(IBAction) sendInAppSMS:(id) sender 
    { 
     MFMessageComposeViewController *controller = [[[MFMessageComposeViewController alloc] init] autorelease]; 
     if([MFMessageComposeViewController canSendText]) 
     { 
      CLLocation *location=[self findCurrentLocation]; 
      CLLocationCoordinate2D coordinae=[location coordinate]; 
      controller.body =[[NSString alloc] initWithFormat:@" Alarm!, call the senders number with latitude:%f longitude:%f",coordinae.latitude,coordinae.longitude]; ; 
      controller.recipients = [NSArray arrayWithObjects:@"phonenumber1", @"phonenumber2", nil]; 
      [self presentModalViewController:controller animated:YES]; 
     } 
    } 

-(CLLocation*)findCurrentLocation 
      { 

      CLLocationManager *locationManager = [[CLLocationManager alloc] init]; 
      if ([locationManager locationServicesEnabled]) 
      { 
       locationManager.delegate = self; 
       locationManager.desiredAccuracy = kCLLocationAccuracyBest; 
       locationManager.distanceFilter = kCLDistanceFilterNone; 
       [locationManager startUpdatingLocation]; 
      } 

      CLLocation *location = [locationManager location]; 
      CLLocationCoordinate2D coordinate = [location coordinate]; 
     return location; 

    }
