概述[{msg = "Hi This is Jecky";name = Susheel;sender = 77;timestamp = 1464241769520;username = susheel;}, {msg = Dubai;name = Jecky;sender = 78;timestamp = 1464246547147;username = Jecky;}, {

[{msg = "Hi This is Jecky";name = Susheel;sender = 77;timestamp = 1464241769520;username = susheel;},{msg = dubai;name = Jecky;sender = 78;timestamp = 1464246547147;username = Jecky;},{msg = "How are you ?";name = Susheel;sender = 77;timestamp = 1464243480381;username = susheel;},{msg = "Aje dekhai nai";name = Jecky;sender = 78;timestamp = 1464244974198;username = Jecky;}]

>我有这样的阵列.我想在swift 2.3或最新版本的swift中使用时间戳对这个数组进行排序.任何人都可以帮助我吗？

解决方法

let array=[        [            "msg":"Hi This is Jecky","name":"Susheel","sender":77,"timestamp":1464241769520,"username":"susheel",],[            "msg":"dubai","name":"Jecky","sender":78,"timestamp":1464246547147,"username":"Jecky",[            "msg":"How are you ?","timestamp":1464243480381,[            "msg":"Aje dekhai nai","timestamp":1464244974198,]    print("array = \(array)")    let sortedArray=array.sort { (obj1,obj2) -> Bool in        return (obj1["timestamp"] as! Double) < (obj2["timestamp"] as! Double)    }    print("sortedArray = \(sortedArray)")
