swift 数组和字典保存到文件中

概述1.保存数组到文件中 //MARK:1，数组（Array）的存储和读取 func testSaveArrayPlist() { let arry = NSArray(objects: "stev","baidu.com","com","12344","robinson") let filePath:String = NSHomeDirectory() +

1.保存数组到文件中

 //MARK:1，数组（Array）的存储和读取    func testSaveArrayPList() {        let arry = NSArray(objects: "stev","baIDu.com","com","12344","robinson")        let filePath:String = NSHomeDirectory() + "/documents/tf.pList"        arry.writetofile(filePath,atomically: true)                tfArray = NSArray(contentsOffile:NSHomeDirectory() + "/documents/tf.pList")                print(tfArray)    }

数组打印结果如下：

Optional(<__NSCFArray 0x7dbba000>(stev,baIDu.com,com,12344,robinson))

2.保存字典到文件中

func testSaveDicPList(){        let  myArray = [                        [                ["name":"小明","url":"Google.com"],["name":"张三","url":"tf234.com"],["name":"里斯","url":"csdn.com"]            ],[                ["name":"张三","url":"csdn.com"]            ]        ]                let filePath:String = NSHomeDirectory() + "/documents/tfDic.pList"        NSArray(array: myArray).writetofile(filePath,atomically: true)        print(filePath)                tfArray = NSArray(contentsOffile:NSHomeDirectory() + "/documents/tfDic.pList")                print(tfArray)    }

字典打印结果如下：

Optional(<__NSCFArray 0x7aa6f4a0>(<__NSCFArray 0x7aa6df50>({    name = "\U822a\U54e5";    url = "hangge.com";},{    name = "\U767e\U5ea6";    url = "baIDu.com";},{    name = Google;    url = Google;}),<__NSCFArray 0x7aa70de0>({    name = 163;    url = "163.com";},{    name = Google;    url = "Google.com";})))
