I have a latitude and longitude that is fixed, so I used that and got the point in mapview with pin. Now I want the current location and draw route, so I think using gps I get the latitude and longitude. Using this location(latitude & longitude) I have to draw a route with my fixed value (latitude & longitude). How is it possible..? Is this is the right way to do it? ?How to draw the route with two point..? I have used the delegate method but it doesn't call, - (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation { [manager stopUpdatingHeading]; NSLog(@"latitude=%f",newLocation.coordinate.latitude); NSLog(@"longitude=%f",newLocation.coordinate.longitude); }

I'm trying to understand the way ARC works, and as far as I know, I should be doing something wrong here. This is the code I'm using: Interface: @interface ViewController : UIViewController{ } @property (strong, nonatomic) NSString * myString ; @property (weak, nonatomic) NSString * myPointer ; Implementation: - (void)viewDidLoad{ [super viewDidLoad]; self.myString = @"Hello world!" ; // myString is strong self.myPointer = self.myString ; // myPointer var is weak [self performSelector:@selector(makeNilMyValue) withObject:nil afterDelay:1]; [self performSelector:@selector(printValues) withObject:nil afterDelay:2]; } - (void) makeNilMyValue{ self.myString = nil ; } - (void) printValues{ NSLog(@"myString: %@", self.myString) ; NSLog(@"myPointer: %@", self.myPointer) ; } After executing this, I get: 2012-02-26 11:40:41.652 test1[933:207] myString: (null) 2012-02-26 11:40:41.653 test1[933:207] myP

How do I fetch all child entities of a parent? I have a table populated by a parent entity in Core Data. When the user touches a cell I intend to show another table with all children of that parent. How does the NSFetchRequest look like for this please?

Thanks!
