I got curious what my binary iphone files contained, so I opened some in a text editor. To my surprise, there are a lot of methods and stuff being mentioned, even in the binaries that are code signed (I thought they got encrypted?). Not that it is a problem, I'm just curios.

I have been searching for this all night and I have just so frustrated. When a MKPinAnnotationView is clicked, the name and the subtitle comes up. I also want to center that point on the view.

I'm writing an iPhone app that has a textField for the user to enter a "dollar amount" like 12.34 None of the SDK keyboards seem to have a decimal point. (OR do they?)
