CLBeacon get the distance from the IBeacons?

How can i get the distance from the iBeacons. i am able to get the

of iBeacons.

But how can i get the distance from the CLBeacon. i have worked with Estimote SDK that gives the distance value. But i dnot how how can i get with the CLBeacon.

- (void)locationManager:(CLLocationManager *)manager
didRangeBeacons:(NSArray *)beacons inRegion:(CLBeaconRegion *)region{

if (self.beaconRegion) {
if([beacons count] > 0)
//get closes beacon and find its major
CLBeacon *beacon = [beacons objectAtIndex:0];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
UITableViewCell *cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:nil];

* Fill the table with beacon data.
ESTBeacon *beacon = [self.beaconsArray objectAtIndex:indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:@"Major: %@, Minor: %@", beacon.major, beacon.minor];
cell.detailTextLabel.text = [NSString stringWithFormat:@"Distance: %.2f", [beacon.distance floatValue]];
[beacon connectToBeacon];
return cell;
-(void)beaconConnectionDidSucceeded:(ESTBeacon *)beacon{
[beacon writeBeaconProximityUUID:@"B9407F30-F5F8-466E-AFF9-25556B57FE6D" withCompletion: ^(NSString *value, NSError *error){
NSLog(@"Got error here: %@",[error description]);
NSLog(@"Congratulation! you've got sucessfully written UUID in beacon");

Accuracy property should give you a distance:

CLBeacon *beacon = [beacons objectAtIndex:0];

If it doesn't work make sure you call startRangingBeaconsInRegion:

[_locationManager startMonitoringForRegion:region];
[_locationManager startRangingBeaconsInRegion:region];
