我正在尝试让我的应用程序能够通过短信将其当前的GPS位置发送到预先输入的电话号码.
我现在有我的代码,只在应用程序内部显示一个SMS窗口,我可以在其中编辑接收号码和正文.我想知道的是我如何得到这个机构的当前位置,以便它可以通过短信发送？无法弄清楚.
-(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];
}
}
解决方法
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",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;
}
