iOS 6中的位置服务无法正常工作

Question

- (void)locationManager:(CLLocationManager *)manager
    didUpdateToLocation:(CLLocation *)newLocation
           fromLocation:(CLLocation *)oldLocation{
    static int i=0;
    if([self getCurrentLocation]==nil){
        i++;
        if(i>3){
            [[self locationManager] stopUpdatingLocation];
            useMyLocation = NO;
            [self locationUpdated];
        }
    }else{
        [self locationUpdated];
    }
}

- (void)alertView:(UIAlertView *)anAlertView clickedButtonAtIndex:(NSInteger)buttonIndex{
if(buttonIndex==1){
    self.useMyLocation = YES;
    [[self locationManager] startUpdatingLocation];
}else{ // buttonIndex==0
    self.useMyLocation = NO;
    [self locationUpdated];
}

}

This is a working code in ios 4 and 5. My problem is that I can't get location to work in ios 6. The app doesn't even asks for permission from the user. After reading around this is what I've tried so far:

• CFBundleDisplayName solution. I already had CFBundleDisplayName in my plist. I tried removing it and adding it again - no go.

• setting the property pausesLocationUpdatesAutomatically of Location Manager to NO like this:

...

- (CLLocationManager *)locationManager{
        if (locationManager != nil){
            return locationManager;
        }   
        CLLocationManager *tmp = [[CLLocationManager alloc] init];
        tmp.pausesLocationUpdatesAutomatically = NO;  //!@#
        [self setLocationManager:tmp];
        [tmp release];
        [locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
        [locationManager setDelegate:self];
        return locationManager;
    }

I also read about locationManager:didUpdateLocations: , I didn't know how to implement it in the code, also i'm not sure if that's the solution.

您是否曾经启动过位置管理器？

[locationManager startUpdatingLocation];
