Updating / changing values ​​in the property list

Question

Can I update values ​​in an existing property list programmatically? If so, how?

I searched a little, but did not find anything.

Thanks.

Answer 1

you can read the list with

[NSMutableDictionary dictionaryWithContentsOfFile:file] 

or

 [NSMutableArray arrayWithContentsOfFile:file] 

Then you can change the Array or Dictionary and write it again with

 [array writeToFile:file atomically:YES] 

Answer 2

If you want to update the runtime of yourapp.infoplist. then the answer is NO.

But if you use a custom plist, you can change it, as @Bernhard Harrer said.
