2 Storing long -lived data

I want to read the cookie, in order to save the cookie, the next time you enter the APP, then take out to use, I wrote

The following two methods, can access the nsmutabledictionary type of data, this type of data, can be understood as key-value pairs, and it is convenient to read and modify a health value through the following two lines of code

2. Read
4. NSString *cookievalue = [cookiedata valueforkey:cookiename];
6. Set / add
8. Nsmutabledictionary *jsoncookie = [[nsmutabledictionary alloc] init];[ Jsoncookie setValue:cookievalue forkey:cookiename];
10. Save data to Local
12. - (BOOL) setlocaldata:(nsstring *)datafile dataObject:( Nsmutabledictionary *)dataObject{
14. Set the path and save
16. nsstring *savepath = [nssearchpathfordirectoriesindomains (nsdocumentdirectory,nsuserdomainmask , Yes) Objectatindex:< Span class= "lit" >0;
18. NSString *saveFile = [savepath stringbyappendingpathcomponent:datafile];[ nskeyedarchiver archiverootobject:dataObject tofile:saveFile];
20. return YES;
22. }
24. To read locally saved data
26. - (nsmutabledictionary *) getlocaldata:(nsstring *)datafile {
28. Read data by file name
30. nsstring *savepath = [nssearchpathfordirectoriesindomains (nsdocumentdirectory,nsuserdomainmask , Yes) Objectatindex:< Span class= "lit" >0;
32. NSString *saveFile = [savepath stringbyappendingpathcomponent:datafile]; return [nskeyedunarchiver unarchiveobjectwithfile: saveFile];
34. }
