Question

I am seeing if there is a way to pass a variable to a button in xcode. I have a web link that I am retrieving from an API that I am storing to a NSString. I am just wondering if there is a way to pass that to a button so that when it is clicked it can follow the link accordingly.

Answer 1

You store that URL lcoally in some ivar or property. You assign an action to your button as usual. The action is nothing less than a method of your view controller. Within that method you execute that link.

This is how you can “follow” your link:

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"http://www.klecker.de"]];

In your case you would use an NSString variable instead of the constant that I am using in this example.
