如何在 Nsuserdefault 中保存为特定值的子值

Question

    Work  
      - Speak with Client
      -Staff meeting
      -Project Delivery

    Home
      -Buy Milk
      -Pickup Your Son
      -Fill Out Water Tank

    Personal

      -Check Diabetes
      -Eat medicines
      -Do Exercise

[[NSUserDefaults standardUserDefaults]setValue:@"Speak with Client"forKey:@“Work"];

I want to save it like under work I required ["Speak with Client","Staff meeting","Project Delivery"]

Example

In Work task list I should have [speak with client,Staff Meeting, Project Delivery]

In Home task list I should have [Buy Milk,Pickup your son, fill out water tank]

How can I save this in Nsuser Default?

Answer 1

Instead of setting the value you can set it as object.

[[NSUserDefaults standardUserDefaults] setObject:yourWorkArray forKey:"Work"];

From Documentation of NSUserDefaults

- (void)setObject:(id)value
           forKey:(NSString *)defaultName

The value parameter can be only property list objects: NSData, NSString, NSNumber, NSDate, NSArray, or NSDictionary. For NSArray and NSDictionary objects, their contents must be property list objects.
