Ex: Click Console: You Touched View: 3 You Touched View: 3 You Touched View: 3 My question: Why does it do it three times? I need it to trigger something other than an NSLog and I'm afraid that it will t...
I'm running into a very annoying issue developing javascript for a UIWebView in an iPhone application. If there is an error in the javascript, it silently fails and halts execution of the function it was running. And some errors do not happen in a desktop browser, so all appears fine.

How can I get NSLog...
