Need to convert NSData to NSArray

Question

I am pulling down a plist from a URL using an NSURLConnection, which returns an NSData object. I would like to convert this to an NSArray. Can anyone help me?

I am refactoring a method that currently does a synchronous request to the URL, using arrayWithContentsOfURL: to get the NSArray.

Thanks!!

Answer 1

Use +[NSPropertyListSerialization dataWithPropertyList:format:options:error:] to convert the data, then check if the result -isKindOfClass:[NSArray class].

Answer 2

Use NSKeyedArchiver for archiving object to data.

NSKeyedUnarchiver for unarchiving object from data:

NSArray *object = [NSKeyedUnarchiver unarchiveObjectWithFile:self.receivedData];
