That is correct, the location services icon will remain on if you have background services enabled. It is however a mistake to think it is the “gps icon” – the arrow icon has nothing to do with GPS per se and simply means that location services are active.

Unfortunately a lot of users think it does mean the GPS is on and draining their battery … and the fact that they are wrong doesn’t really help us developers when using background location services!

Sadly this is the way the location services are designed by Apple. Perhaps in a future OS release they will make the icon sufficiently different for background use that the users will also pick up on this.

Until then … all we can do is try to inform them in the application.

That said, try it and see – that’s always the best way of testing these ideas out. I’d have thought you would be fine, but I haven’t looked in detail.

- (void)applicationWillTerminate:(UIApplication *)application {
[locationManager startMonitoringSignificantLocationChanges];
}

and when the app opens i do
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// initialize location manager

if ([launchOptions objectForKey:UIApplicationLaunchOptionsLocationKey] ) {
[locationManager startMonitoringSignificantLocationChanges];
}

else{
[locationManager startUpdatingLocation];

}

return YES;
}

Also i use UIBackgroundModes locations in plist so location updates keep working as not when app is minimized.

Any thoughts on this?

Because BOOL is essentially a primitive type, ‘self’ isn’t necessary – a BOOL is an instance variable rather
than a property. As such, a property declaration is only necessary if access is needed from other objects. Internally, ‘self.myBOOL’ and ‘myBOOL’ reduce to the same thing because the accessor for primitive types should simply be ‘assign’.

Both work as you would expect and because we are dealing with primitives, there’s no difference in the outcome between these two forms. I’m not aware of any convention here amongst Objective-C programmers, so my guess is that it comes down to your own preference!

BOOL gatheringFeaturedDataBool;
@property (readwrite, assign) BOOL gatheringFeaturedDataBool;

@synthesize gatheringFeaturedDataBool;

self.gatheringFeaturedDataBool = NO;

if (!self.gatheringFeaturedDataBool) {
[self networkCheckAndDecide];
}

Thanks!

Blue Plaques, not another blue plaque mapping program! Didn’t the judges think to use Google to search for blue plaque mapping software? eg. a search for blue plaque map shows http://blue.plaquemap.com/ or http://blueplaquelondon.co.uk/ and loads more.

Geovation started with such potential, there were some great ideas submitted, some better than mine, most better and more innovative than the winners. To call this an award for innovation then award it to projects that were copies seems perverse.
