Question

I have a plist file in my document directory.

I need to delete some key with their value programatically.

Answer 1

First I would read in the plist in

get the URL of the plist and read it in

 NSData *plistXML = [[NSFileManager defaultManager] contentsAtPath:plistPath];

then break it down into objects. plist are just a hierarchy of different NSObjects usually the root is an Array or a dictionary.

NSDictionary *plistData = (NSDictionary *)[NSPropertyListSerialization propertyListFromData:plistXML mutabilityOption:NSPropertyListMutableContainersAndLeaves format:&format errorDescription:&error];

Modify the dictionary then re-write it to the documents folder.
