Question

I would know if it’s possible to save data in a plist document and how accessing to it through the code.

Answer 1

A plist is nothing more than an xml document. It would be useful to know what programming language are you wanting to use as well. Objective-c for the iPhone has support through NSDictionary. .NET has some interpreters out there as well.

NSDictionary *myDic = [[NSDictionary alloc] initWithContentsOfFile:path];
