Property List vs XML in iPhone

Question

I have to save some config parameters with values in iPhone. I need to edit values at app runtime. I see there are two ways to implement this:
1. Use pList file
2. Create new XML file.
What is the best approach to implement this? Should I use existing Info.pList file?

Thanks

Answer 1

The best solution is probably using a dictionary and saving that to a property list, it's incredibly easy. Do not use the existing Info.plist, you don't want to polute it with your own settings.

Here's a quick exaple on how to save a dictionary to a property list and load it:

An Info.plist file is XML, it is directly readable from a file to a NSDictionary or NSArray. You can also choose the file format as XML or a binary format, the binary format is a lot smaller and can load faster especially over a network.
