距離的字串
給定 CLLocationDistance
(簡稱為表示米的 Double
),輸出使用者可讀的字串:
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"
預設情況下,這會考慮使用者的區域設定。
