Question

I am using the following code snippet for an app I’m working on to print a list of words on the iPhone screen:

    NSString *labelText = [[NSString alloc] initWithFormat:@"%@", [self.dictionary selectList]];
//creates a string list from an NSDictionary key with a value of an NSArray that has NSString objects in it
    self.listLabel.text = labelText;
//displays list in label

The listed words are displayed on multiple lines in a label, but the array is bookended by parentheses and is separated by commas.

For example, if i have an NSDictionary key @”Cat” which has an NSArray value added to it like so: @”snow leopard”, @”lion”, @”tiger”, then my output on screen will be the following:

(
snow leopard,
lion,
tiger
)

Is there a way to get rid of this punctuation?

Thank you!

That’s not really the purpose of the description method, what’s implicitly being called to form that string. You should use the following:

[[self.dictionary selectList] componentsJoinedByString:@" "];

Which will take an array and join it with spaces between each item.
