How to stop CLLocation manager updating IMMEDIATELY - iphone

Question

I am having ClLocationManager code in my viewWillAppear. I the same view controller I am having a button which opens a web view. I want to stop location manager IMMEDIATELY, when user taps on button. I am using [locationManager stopUpdating] and locationManager.delegate = nil. From CLLOCATION delegate method I open MFMailComposer sheet.
Problem: Even after clicking on button (which is opening web view), my MailComposerCode executes. How to stop it?
-(void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
[self setUpProgressBar];
if (webViewButtonClicked == YES)//when user came bck from web view pick up latest coordinates
{
webViewButtonClicked = NO;
[self getLocationCoordinates];
}
else//get latest coordinates from CLLocation manger
{
if (!locationManager) {
locationManager = [[CLLocationManager alloc] init];
}
if (!self.geocoder) {
self.geocoder = [[CLGeocoder alloc] init];
}
locationManager.delegate = self;
// This is the most important property to set for the manager. It ultimately determines how the manager will
// attempt to acquire location and thus, the amount of power that will be consumed.
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
// When "tracking" the user, the distance filter can be used to control the frequency with which location measurements
// are delivered by the manager. If the change in distance is less than the filter, a location will not be delivered.
locationManager.distanceFilter = kCLLocationAccuracyNearestTenMeters;
// Once configured, the location manager must be "started".
[locationManager startUpdatingLocation];
}
}
- (IBAction)goToWEBVIEW
{
NSLog(#"setting to YES");
webViewButtonClicked = YES;
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
aWebViewController = [[WebViewController alloc] initWithNibName:#"WebViewController" bundle:nil];
[self.navigationController aWebViewController animated:NO];
}
CLLocationManager delegate method:
-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
if (webViewButtonClicked==NO)
{
NSLog(#"1234");
if (!self.sender) {
[self.gpsActivityindicator stopAnimating];
[self stopUpdatingLocation:#""];
self.destinationForProgressView = .25;
[NSThread detachNewThreadSelector:#selector(startTheBackgroundJob) toTarget:self withObject:nil];
**[self openMailComposer];**
}
}
}
So you can see in goToWebView method I am having a flag webViewButtonClicked = YES, but delegate method is called before the user has tapped on web view button. So condition if (webViewButtonClicked==NO) becomes true? How can I stop this scenario?
Thanks.

- (IBAction)goToWEBVIEW
{
[locationManager stopUpdatingLocation];
NSLog(#"setting to YES");
webViewButtonClicked = YES;
[locationManager stopUpdatingLocation];
locationManager.delegate = nil;
aWebViewController = [[WebViewController alloc] initWithNibName:#"WebViewController" bundle:nil];
[self.navigationController aWebViewController animated:NO];}

-(void)locationManager:(CLLocationManager *)manager didUpdateLocations:(NSArray *)locations{
[locationManager stopUpdatingLocation];
if (webViewButtonClicked==NO)
{
NSLog(#"1234");
if (!self.sender) {
[self.gpsActivityindicator stopAnimating];
[self stopUpdatingLocation:#""];
self.destinationForProgressView = .25;
[NSThread detachNewThreadSelector:#selector(startTheBackgroundJob) toTarget:self withObject:nil];
**[self openMailComposer];**
}
}
}
