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)
    }

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)
    }

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";
}
)

)
