creating a plist file programatically

Question

this question is regarding xcode objective c and iphone development:

So i want to store an array in a new plist file and I know how to retrieve the file path and write the data into the file (at least i think i do) and all that jazz once the plist is created, but how do I actually create the plist file the first time the app is run or the first time I go to enter data into it? I want it to live in the documents folder of my app.

I'm assuming this is pretty simple I just can't seem to find documentation on it.

Answer 1

[myArray writeToFile:aFile atomically:YES];

Answer 2

To save:

NSMutableArray *array = [[NSMutableArray alloc] init];
[array writeToFile:[@"/path/to/file.plist"] atomically: TRUE];

To retrieve:

NSMutableArray *array = [[NSMutableArray arrayWithContentsOfFile:[@"/path/to/file.plist"]] retain];

Answer 3

Apple's guide to creating plist's programmatically

Does a pretty good job explaining what a plist is and how to structure it to your liking.

Answer 4

I ended up using NSKeyedValue there was a great tutorial here:

I know technically this is not the answer to the question but it did solve my problem.
