NSUserDefaults NSMutable Array Not Saving Between Sessions

I have an NSMutableArray stored in NSUserDefaults. The mutable array is properly edited and the results of the edit can be viewed with:

NSLog(@"%@", [[NSUserDefaults standardUserDefaults] dictionaryRepresentation]);

However, when I quit and relaunch the application, the user defaults are back to their original form.

I try to save state by running this method to force synchronization:

-(void) saveUserDefaults{
if([[NSUserDefaults standardUserDefaults] synchronize]){
    NSLog(@"Defaults saved");
}else{
    NSLog(@"Defaults save failed");
}

NSLog(@"%@", [[NSUserDefaults standardUserDefaults] dictionaryRepresentation]);

}

Are there any ideas why this might not be saving?

I set the user default arrays using this code the first time the application is run:

// Check if first time run
if ([[[NSUserDefaults standardUserDefaults开发者_运维技巧] objectForKey:@"isFirstRun"] isEqualToString:@"no"]) {

    // Not first run, NSUserDefault arrays are already set
}else {
    // First Run of Program 
    // Mark for future
    [[NSUserDefaults standardUserDefaults] setObject:@"no" forKey:@"isFirstRun"];

Do you mean you set the default to an NSMutableArray and then if you change the mutable array outside of the defaults, you lose the changes?

If so, the defaults probably haven't noticed that you have changed the array. You need to create a new array and send -setObject:forKey: again (or use the same mutable array and send -setObject:forKey:).

By the way, the docs say you can only pass an NSArray. That doesn't mean you can't pass NSMutableArray but you need to keep to the spirit of the contract and not change the array you pass in.

When are you calling saveUserDefaults?

I would also recommend only calling [NSUserDefaults standardUserDefaults] once inside a method. Just keep a pointer to the object and use it again and again, like so:

NSMutableArray *designerArray = [[NSMutableArray alloc] initWithObjects: @"Alberta Ferretti" ...;


NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setObject:designerArray forKey:@"designerArray"];
[defaults synchronize];

I used the above code with your designer array and it worked for me.

This worked for me. I pretty much had to reassign the array to itself.

[standardDefaults setObject:[standardDefaults objectForKey:@"designerArray"] forKey:@"designerArray"];
