I have a custom class, derived from UIView, called Element. In Element I set up some IBOutlets to handle some UIImageViews I have in my XIB. My ViewController adds the Element object to a larger view where the Element moves around. And I added an Object with class Element in IB, and connected the Outlets up through that. But in my Eleme...
I use a .xib to layout my viewController and have 10 IBOutlet objects that IB uses, none of them have @properties assigned to them (no @property(retain) IBOutlet...). When I release the viewController none of those objects are being released, I have to manually release them in the dealloc of the viewController. This doesn't seem like n...
I'm building from command-line using the xcodebuild utility. The build results is being stdout as plain-text, in a very unreadable format. I would like to save the build results in a (binary?) file, which, if double-clicked, will be opened in the XCode application itself, thus I will be able to read the build results from the application...

Hey there, There's a bug in OS 4.1 that has broken location services for some iPhone apps ( https://devforums.apple.com/message/306250 ). Basically location services fails to turn on, and doesn't even ask the user for permission to get their location. The worst thing about the bug is that it doesn't occur when you're installing the app ...
