I have a question about something I've been working on for a while. I have a UIPickerView that lists different types of food. My array looks like such:

```
food = [[NSMutableArray alloc] init];
    [activities addObject:@"Pasta"];
    [activities addObject:@"Pizza"];
    [activities addObject:@"Spaghetti"];
    [activities addObject:@"Salad"];

```

And my image array is:

```
foodImages = [[NSMutableArray alloc] init];
        [activities addObject:@"Pasta.png"];
        [activities addObject:@"Pizza.png"];
        [activities addObject:@"Spaghetti.png"];
        [activities addObject:@"Salad.png"];

```

What I am trying to find out is if when the user selects an item from the picker view if I can change the image of a button. So if pasta is selected from the UIPickerView it would change the image of the button to "Pasta.png". How could I go about achieving this in Xcode?
