Question: How to create Latitude-Longitude bounds in iPhone using two NE and SW latitude longitude coordinates and I want to check whether my current latitude longitude is in within my latitude longitude bound. 

I created a bound using following latitude longitude coordinates:

```
double minLng = 7.880571
double maxLng = 8.357336
double minLat = 49.108775
double maxLat = 49.288638

```

I want to check my other latitude longitude is within this bound or not.

Answer: 
Try like this,

```
CLLocationManager *locationManager = [[CLLocationManager alloc] init];
locationManager.delegate = self;
locationManager.distanceFilter = kCLDistanceFilterNone;
locationManager.desiredAccuracy = kCLLocationAccuracyBest;
[locationManager startUpdatingLocation];

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation {

    if(newLocation.coordinate.latitude>=49.108775 && newLocation.coordinate.latitude<=49.288638 && newLocation.coordinate.longitude>=7.880571 && newLocation.coordinate.longitude<=8.357336 ) {

         // It is in the bounds

    }
}

```
If by current you mean the device's current location, you need to look into the [CLLocationManager](https://developer.apple.com/library/mac/#documentation/CoreLocation/Reference/CLLocationManager_Class/CLLocationManager/CLLocationManager.html) class and its delegate methods, namely the `location` property which contains the information about current latitude and longitude. The rest is pretty straightforward.
