Swift的NSUserDefaults数据存取

简单的先存再取一个一个数组，然后数组里有一个dictionary

        let dict1 = ["1":1,"2":2,"3":"3"]
        let array1 = [ dict1 , dict1 , dict1 , dict1 ]
        
        NSUserDefaults.standardUserDefaults().setObject(array1, forKey : "animals" )
        NSUserDefaults.standardUserDefaults().synchronize ()
        
        let animals = NSUserDefaults .standardUserDefaults().objectForKey ( "animals" )
        print( "We saved this data: \( animals )" )

简单的先取，再存一个数组，然后数组里有一个dictionary

        let userDefaults = NSUserDefaults.standardUserDefaults()
        var arr = [[String: String]()]
        if let a = userDefaults.objectForKey("commonfile") {
            arr = a as! [[String : String]]
        }
        else{
            arr = []
        }
        let dict = ["name":"1","time":"2016-03-15","totaltime":"02:48"]
        arr+=[dict]
        userDefaults .setObject(arr, forKey: "commonfile")
        userDefaults.synchronize()
