didUpdateToLocation is not called in app - ios

Question

I want to receive location updates. I have added a location delegate to the header file but didUpdateToLocation method not fire my code is
#interface FirstViewController : UIViewController <CLLocationManagerDelegate>
{
UILabel *myLabel;
CLLocationManager *manager;
CLGeocoder *geocoder;
CLPlacemark *placemark;
}
-(void) showCurrentLocation;
#end
and .m file like this:
#import "FirstViewController.h"
#interface FirstViewController ()
#end
#implementation FirstViewController
-(id) init
{
self=[super init];
if (self) {
self.view.backgroundColor=[UIColor purpleColor];
self.edgesForExtendedLayout=UIRectEdgeNone;
[self showCurrentLocation];
}
return self;
}
-(void) showCurrentLocation{
manager=[[CLLocationManager alloc] init];
manager.pausesLocationUpdatesAutomatically=NO;
geocoder=[[CLGeocoder alloc] init];
manager.delegate=self;
manager.desiredAccuracy=kCLLocationAccuracyBest;
}
-(void) locationManager:(CLLocationManager *)manager didFailWithError:(NSError *)error
{
NSLog(#"Error %#",error);
NSLog(#"Faild to get location");
}
-(void) locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation
{
NSLog(#"Location %#",newLocation);
CLLocation *currentlocation=newLocation;
if (currentlocation!=nil)
{
myLabel=[[UILabel alloc] initWithFrame:CGRectMake(30, 30, 200, 200)];
[myLabel setText:[NSString stringWithFormat:#"Latit %8f",currentlocation.coordinate.latitude]];
myLabel.textColor=[UIColor whiteColor];
[self.view addSubview:myLabel];
[geocoder reverseGeocodeLocation:currentlocation completionHandler:^(NSArray *placemark1 ,NSError *erroe){
if (erroe==nil && [placemark1 count]>0)
{
NSLog(#"Location");
}
else
{
NSLog(#"error 2 %#",erroe.debugDescription);
}
}];
}
}

You need to start location manager
manager = [CLLocationManager new];
manager.delegate = self;
[manager startUpdatingLocation]; // forgotten in the code above
Also be sure that you setup your scheme properly to simulate location in test mode via Simulator
