uiviewcontroller

问题 I created a subclass of UIViewController. In it I have two properties of: @property (nonatomic, retain) IBOutlet UIView *presetsView; @property (nonatomic, retain) IBOutlet UIView *customView; I added a new UIView to my .xib and put some UI elements in it. I want to hide one view, and show the other based on when the UISegmentedControl is pressed. My question is in Interface Builder, my original View that was provided me by IB, has an outlet connected to it already to File's Owner. Because I

This was my attempt to solve the issue but it doesn't make a difference and it doesn't look clean. -(void)viewDidDisappear:(BOOL)animated{ ViewController *me = self; me =

问题 I just want to know the code for making an image called profpic accessible to all other ViewControllers that I make or intend to make. I have read many posts on global variables, public variables, and other suggestions that have yet to work. If it helps, I am specifically using this to display an image from ViewControllerA as the background for ViewControllerB . 回答1: You can use a singleton class and put the UIImage on it. Set it in ViewControllerA and get it in ViewControllerB @interface
