Writing and reading text files on the iPhone

Question

As a practice, I am trying to write an app similar to the built-in notes app.
But I cannot figure out how to save the file and display it in a UIT

Answer 1

The easiest way to save text is using NSUserDefaults.

[[NSUserDefaults standardUserDefaults] setObject:theText forKey:@"SavedTextKey"];

or, if you want to have the user name each "file" or be able to have multiple files

NSMutableDictionary *saveTextDict = [[[[NSUserDefaults standardUserDefaults] objectForKey:@"SavedTextKey"] mutableCopy] autorelease];
if (saveTextDict == nil) {
    saveTextDict = [NSMutableDictionary dictionary];
}

[saveTextDict setObject:theText forKey:fileName];
[[NSUserDefaults standardUserDefaults] setObject:saveTextDict forKey:@SavedTextKey"];
