Question

I created one custom class & created object for that class. I want to store that object into NSUserDefault. I am getting error while set the object into userfaults. How can I set?

Answer 1

You have to implement the NSCoding protocol in your class & implement the protocols methods.
This is simply serialization. While storing the object you should serialize(NSKeyedArchiver) the class & same as retrieval you should unserialize(NSKeyedUnArchiver) that object.

the methods are

• (void)encodeWithCoder:(NSCoder *)aCoder;
• (id)initWithCoder:(NSCoder *)aDecoder;
