CLLocationManager not calling its delegate method - ios

Question

I am developing an app which involves tracking the new location and updates to the server in X mins. I am stopping the location updating when the time diff is equal to or greater than X mins, then sending to the server and then start updating the location if it is less than X mins. But the didUpdateToLocation delegate methos is not called when it is less than X mins.
I am posting my code here:
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation
{
if (theDiff > 10.0f || myDate == nil)
{
[self stopUpdating];
}
else
{
[self.mLocationManager startUpdatingLocation];
}
}

Answer 1

try this.,
//in your .h
CLLocationManager *locationManager;
#property (nonatomic,retain) CLLocationManager *locationManager;
// Then synthesize it in your .m
#synthesize locationManager;
//in your viewDidLoad
locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone; // whenever we move
locationManager.desiredAccuracy = kCLLocationAccuracyHundredMeters; // 100 m
[locationManager startUpdatingLocation];
This will call the method whwnever you move with your phone. You can check this by changing simulator locatin also.
Hope this helps., Thanks, happy coding.

try this in .m add this method , or if you have any other custom code post it
-(void)LocationWithTime
{
[CLController sharedInstance].locationManager.desiredAccuracy = 100.0;
[CLController sharedInstance].delegate = self;
BOOL locationAccessAllowed = NO ;
if( [CLLocationManager respondsToSelector:#selector(locationServicesEnabled)] )
{
locationAccessAllowed = [CLLocationManager locationServicesEnabled] ;
}
if(locationAccessAllowed == YES)
{
[[CLController sharedInstance].locationManager startUpdatingLocation];
}
}
this is the delegate method i have used -
-(void)newLocationUpdate:(NSString *)latvalue longValue:(NSString*)longvalue Error:(int) errCode
{
DebugLog(#"LatLong values %# %#", [UserContext sharedInstance].strLat, [UserContext sharedInstance].strLong);
self.strLALat = latvalue;
self.strLALong = longvalue;
[[CLController sharedInstance].locationManager stopUpdatingLocation];
[CLController sharedInstance].delegate=nil ;
}

Excerpt from Apple API Documentation,
/*
* locationManager:didUpdateToLocation:fromLocation:
*
* This method is deprecated. If locationManager:didUpdateLocations: is
* implemented, this method will not be called.
*/
- (void)locationManager:(CLLocationManager *)manager
didUpdateToLocation:(CLLocation *)newLocation
fromLocation:(CLLocation *)oldLocation __OSX_AVAILABLE_BUT_DEPRECATED(__MAC_10_6, __MAC_NA, __IPHONE_2_0, __IPHONE_6_0);
Use the below delegate method instead,
/*
* locationManager:didUpdateLocations:
* locations is an array of CLLocation objects in chronological order.
*/
- (void)locationManager:(CLLocationManager *)manager
didUpdateLocations:(NSArray *)locations __OSX_AVAILABLE_STARTING(__MAC_NA,__IPHONE_6_0);
This will work once you set the delegate.
Hope this helps.
