问题 I have created a project in Xcode using storyboards. I created a segue between two of the view controllers with a button using the click and drag method. However, there are a certain set of conditions that I want to be met in order for the segue to happen. So I already coded the button as an IB action and wrote the conditional code in the implementation file. If the conditions are not met, an alert view pops up, and I don't want the segue to happen.

问题 What i would like to do is a simple button with an action method, This button is initialized, created, assigned to its action method and shown ONLY in Debug and AdHoc modes.

问题 I'm still learning iOS development and have been working with various tutorials and books. Some pre-ARC, some with ARC. In some cases, we're taught to release all of the properties and subviews of a ViewController on viewDidUnload but in some cases I've been told this is no longer required.
