Creating a UIImageView using an NSString

Question

I have to create a number of UIImageViews based on values stored in an NSString. The value that is stored will become the name for my UIImageView, each one will be created individually of course.

So to keep things simple my question is, can one create a UIImageView based on the value stored within an NSString?

Rough Example:

-(UIImageView)createMyFruitViews:(NSString *)fruit
{
    NSString *fruit = @"";
    UIImageView *fruitImage [fruit value]; //<-- made up for example purposes.
    return fruitImage;
}

If this is not possible, could you please suggest a way around this?

FYI I've read through the forums too, the only thing that comes close is How to use NSSstring to instantiate a UIImageview; however I don't understand the answer and I am not sure that it can apply to what I need.

Try using UIImageView *fruitImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:fruit]];

I'm not quite sure I understood what you need... as far as I can tell, you have the name of an image on a NSString object, right?

Lets say you have an array of strings, each string representing the name of an image:

NSArray *myImageNames = [NSArray arrayWithObjects:@"image1.png", @"image2.png", @"image3.png", nil];

Then you'll create your imageViews using these images:

for (NSString *imageName in myImageNames) {
    UIImageView *myImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:imageName]];
    [self.view addSubview:myImageView];
    [myImageView release]; // If you're not using ARC
}

If I didn't get exactly what you need, please let me know.
