Get image location from iOS UIImagePickerController - ios

Question

I am try to develop iOS app which get the location of the Photo using UIImagePickerController and display it I am deploying it on iOS 7 device Here is what i did .
- (IBAction)takePhoto:(id)sender
{
UIImagePickerController *picker = [[UIImagePickerController alloc] init];
picker.delegate = self;
picker.sourceType = UIImagePickerControllerSourceTypeCamera;
picker.cameraDevice = UIImagePickerControllerCameraDeviceRear;
picker.showsCameraControls = YES;
[self presentViewController:picker animated:YES
completion:^ {
// [picker takePicture];
}];}
-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSLog(#"Media Info: %#", info);
NSString *mediaType = [info valueForKey:UIImagePickerControllerMediaType];
ALAssetsLibraryAssetForURLResultBlock resultblock = ^(ALAsset *myasset)
{
// Get the location property from the asset
CLLocation *location = [myasset valueForProperty:ALAssetPropertyLocation];
// I found that the easiest way is to send the location to another method
latitude =location.coordinate.latitude; //[[gpsdata valueForKey:#"Latitude"]floatValue];
longitutde =location.coordinate.longitude;
NSString * strLocation=[NSString stringWithFormat:#"La:%f Lo%f",latitude,longitutde];
};
// This block will handle errors:
ALAssetsLibraryAccessFailureBlock failureblock = ^(NSError *myerror)
{
NSLog(#"Can not get asset - %#",[myerror localizedDescription]);
// Do something to handle the error
};
if([mediaType isEqualToString:(NSString*)kUTTypeImage]) {
UIImage *photoTaken = [info objectForKey:#"UIImagePickerControllerOriginalImage"];
//Save Photo to library only if it wasnt already saved i.e. its just been taken
if (picker.sourceType == UIImagePickerControllerSourceTypeCamera) {
UIImageWriteToSavedPhotosAlbum(photoTaken, self, #selector(image:didFinishSavingWithError:contextInfo:), nil);
}
}
[picker dismissModalViewControllerAnimated:YES];
}
- (void)image:(UIImage *)image didFinishSavingWithError:(NSError *)error contextInfo:(void *)contextInfo {
UIAlertView *alert;
//NSLog(#"Image:%#", image);
if (error) {
alert = [[UIAlertView alloc] initWithTitle:#"Error!"
message:[error localizedDescription]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
}
}
- (void)imagePickerControllerDidCancel:(UIImagePickerController *)picker {
[picker dismissModalViewControllerAnimated:YES];
}
I am not able to get .How to get the location ? please help me on this .

Answer 1

in the delegate implementation you can use the path of the image or the image itself:
// This method is called when an image has been chosen from the library or taken from the camera.
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
//You can retrieve the actual UIImage
UIImage *image = [info valueForKey:UIImagePickerControllerOriginalImage];
//Or you can get the image url from AssetsLibrary
NSURL *path = [info valueForKey:UIImagePickerControllerReferenceURL];
[picker dismissViewControllerAnimated:YES completion:^{
}];
}

Location Services Should be enabled when the photo was taken.Try same code by enabling location services.
