Archive the object property list into a plist file in iOS

Archive steps:

1. Archive a Nsdictionary object to a list of plist attributes

<1> first to encapsulate the data into a dictionary:

Nsmutabledictionary * Dict = [nsmutabledctionary dictionary];

[Dict setobject:@ "soot" forkey:@ "name"];

[Dict setobject:@ "1234567" forkey:@ "PhoneNumber"];

[Dict setobject:@ "forkey:@" "Age"];

<2> keep the dictionary permanently in the file

[Dict Writetofile:path Atomically:yes]; (Path is the file to which the data is to be written, for example:/users/apple/library/application support/iphone simulator/6.0/applications/documents/ Stu.plist)

2. Read the attribute list

To restore the Nsdictionary object when reading the property list

Nsdictionary * dict = [nsdictionary Dictionarywithcontentsoffile:path];

NSLog (@ "name:%@", [dict objectforkey:@ "name"]);

NSLog (@ "phonenumber:%@", [dict objectforkey:@ "PhoneNumber"]);

NSLog (@ "age:%@", [Dict objectforkey:@ "Age"]);

The flowchart is as follows:
