MKDistanceFormatter

String from distance

Given a CLLocationDistance (simply a Double representing meters), output a user-readable string:

let distance = CLLocationDistance(42)
let formatter = MKDistanceFormatter()
let answer = formatter.stringFromDistance(distance)
// answer = "150 feet"

Objective-C

CLLocationDistance distance=42;
MKDistanceFormatter *formatter=[[MKDistanceFormatter alloc]init];
NSString *answer=[formatter stringFromDistance:distance];
// answer = "150 feet"

By default, this respects the user's locale.

Distance units

import Mapkit Set units to one of .Default, .Metric, .Imperial, .ImperialWithYards:

formatter.units = .Metric
var answer = formatter.stringFromDistance(distance)
// "40 m"

formatter.units = .ImperialWithYards
answer = formatter.stringFromDistance(distance)
// "50 yards"

Objective-C

MKDistanceFormatter *formatter=[[MKDistanceFormatter alloc]init];
formatter.units=MKDistanceFormatterUnitsMetric;
NSString *answer=[formatter stringFromDistance:distance];
//40 m

formatter.units=MKDistanceFormatterUnitsImperialWithYards;
NSString *answer=[formatter stringFromDistance:distance];
//50 yards

Unit style

Set unitStyle to one of .Default, .Abbreviated, .Full:

formatter.unitStyle = .Full
var answer = formatter.stringFromDistance(distance)
// "150 feet"

formatter.unitStyle = .Abbreviated
answer = formatter.stringFromDistance(distance)
// "150 ft"

Objective-C

formatter.unitStyle=MKDistanceFormatterUnitStyleFull;
NSString *answer=[formatter stringFromDistance:distance];
// "150 feet"

 formatter.unitStyle=MKDistanceFormatterUnitStyleAbbreviated;
 NSString *answer=[formatter stringFromDistance:distance];
// "150 ft"
