Is there a way to connect code to a view's 'back' button that is part of a navigation controller? That back button is automatically coded in by the nature of it being a navigation controller so I am not sure how I can connect code to it. (I know this should be really easy but I can't seem to find it in the documentation on navigation c...

I'm guessing no, but would love to be wrong. I would like to use a bundle display name for my universal app that shows great on the iPad and iPhone 4, but is too long (has ellipses) on older iPhone models. I'd like to specify the full bundle display name on the former two platforms, and then specify a shorter name on older iPhone models....

Hi, I've seen people using tags in iphone programming, like inside labels or tableview cells: name.tag = kNameTag Can someone explain with an example how these tags might be used? I gather that it's so that you can refer to a ui element later? Like if you programmatically use a for loop to create an array of UIButtons onto the iphone...

Hey there, I'm having difficulties with adopting the UIKeyInput Protocol with Core Text. I currently have most of it done as posted in the source code, however for some reason it glitches as it types, with incorrect font height for the first letter of each new line, which doesn't really make much sense since it's just drawing whatever is...

Ok I want to keep track of how many times my iPhone App has been launched. I will be using this number for a "leader board" for our most active user.

But suppose I build a local network webapp, let's say at 192.168.1.100, then I leave my house, and i'm off the network, then I try to hit that address. Will the webapp pull from the cache, or will it say, "you have internet, but the host is unreachable...
