Is it possible to create mutable versions of objects read in from a plist

Question

I\'m reading into my application a plist which at the top level is an array. It\'s simple enough to make sure the array starts as mutable

self.plistData = [         


        

Answer 1

The simplest approach is to use NSPropertyListSerialization and passing the proper options to get mutable containers.

NSString *path = [[NSBundle mainBundle] pathForResource:@"myDataSource" ofType:@"plist"];
NSData *data = [NSData dataWithContentsOfFile:path];
NSMutableArray *array = [NSPropertyListSerialization propertyListWithData:data options:NSPropertyListMutableContainers format:nil error:nil];
self.plistData = array;

Ideally you will make use of the error parameter and do proper error checking but this will get you started.

This code will load the plist and return a mutable array and every contained array and dictionary will also be mutable.
