When using #UITableViewDelegate #didSelectRowAtIndexPath , with #UINavigationController as parent, should pushViewController before setItem?
First time to play #UISplitViewController ? Do not get forget to override sub-viewcontrollers' #shouldAutorotateToInterfaceOrientation:
The screen will flash indicating that a screen shot is captured and the resulting image is placed in your photos folder.
To capture a screen shot hold down the home button and press the top button.
#MemoryManagement is number 1 killer of iOS developers.
#iOS #NSZombieEnabled will save your brain, not eating.
solution: it depends on whether the sender object is released or retained at the place it is created. Think of #UIImagePickerController
challenge: #iOS someone does [sender #autorelease] in delegate methods. Something it works, sometimes it crashes.
#iOS #awakeFromNib after #initWithCoder iOS is strategized for lazy loading
#iPad #weak-link. Got crash before iPad app start up, because of non-weak linking to #CoreVideo and #CoreMedia
#iPad - use #UIPopoverController to present #UIImagePickerController, not any ViewContoller's presentModal.
#iPad Better and easier to start up developing Universal Apps from Window-based template, rather than "Upgrade Current Target for iPad"
