iOS保存數(shù)據(jù)有很多種方式，這里提供一種使用字典保存數(shù)據(jù)的方法

//構(gòu)建文件路徑

let?path?=?NSSearchPathForDirectoriesInDomains(NSSearchPathDirectory.DocumentDirectory,?NSSearchPathDomainMask.UserDomainMask,true)[0].stringByAppendingPathComponent("contacts.data");

NSLog("Path:%@",?path);

//從文件加載數(shù)據(jù)

var?arr?=?NSMutableDictionary(contentsOfFile:?path);

//arr?.removeAllObjects();//清理數(shù)據(jù)

//賦值

let?index?=?arc4random();//隨機(jī)數(shù)

var?k?=?String(index);//鍵

var?v?="abc?-?"+String(index)//值

//設(shè)置數(shù)據(jù)

arr?.setObject(v,forKey:?k);

//保存數(shù)據(jù)到文件

var?ok?=?arr?.writeToFile(path,atomically:true)

NSLog("Write:%@",ok!)

//打印數(shù)據(jù)

if(arr?!=nil){

foritem?in?arr!.keyEnumerator()?{

let?s?:??String?=?arr?.valueForKey(item?as!?String)?as!?String;

NSLog("k:%@?v:%@",?item?as!?String,?s);

}

}

謝謝!!!
