Why is Xcode thinking my variable is returning an NSURL when it should be returning an NSString?
ios, ios5, ios6, objective-c, xcode
Solution
The problem is that `self.articles[row]` will be returning an object of type `id`, which means that the Objective-C runtime can't figure out which method implementation applies. It's finding a `URL` method in another interface and using that one.
There's more information about this problem in the article A big weakness in Objective-C's weak typing by Matt Gallagher.
Problem
I get the following warning: "Incompatible pointer types assigning NSString from NSURL". Here's the code in question: ``` cell.articleURL.text = [self.articles[row] URL]; ``` I'm assigning a label the value of an Article object's URL property. The self.articles array is only used to hold Article objects. In the Article class I have this: ``` @property (nonatomic, strong) NSString *URL; ``` Why is it thinking it's an NSURL?
