I want to know the key difference between awakeFromNib() and viewDidLoad() to get more clarity on how it works . Please can anybody explain? From Apple documentation: awakeFromNib : The nib-loading infrastructure sends an awakeFromNib message to each object recreated from a nib archive, but only after all the objects in the archive have been loaded and initialized. When an object receives an awakeFromNib message, it is guaranteed to have all its outlet and action connections already established. See: Nib Files in Resource Programming Guide viewDidLoad : This method is called after the view

Does Android have an equivalent to Cocoa's viewDidLoad and viewDidAppear functions? If not, then how would I go about performing an action when a View appears? My app is a tabbed application, in which one of the tabs is a list of forum topics. I would like the topic list to be refreshed every time the view appears. Is such a thing possible in Android? The Activity class has onCreate and onResume methods that are pretty analagous to viewDidLoad and viewDidAppear. Activity.onResume EDIT To add to this, since some have mentioned in the comments that the view tree is not yet fully available during

I'm trying to figure out from Apple's sketchy documentation which method is the best place to be initializing and adding my Views controls to the controller's view. With winforms it's fairly straightforward, as they're always initialized inside InitializeDesigner , called in the constructor. I'm trying to match the reliability of this pattern if possible. I'm working with UIViewControllers and UITableViewControllers inside a UINavigationController most of the time - if this effects it all. Here's an example: public MyController() { // Here? AddViews(); } public override ViewDidLoad() { base

I have two window app and while I present first window I would like the view in second window to load and prepare content for later in background. I've tried to use method loadView but Apple says you should not call this method directly. So far I've chosen to use the view's method userInteractionEnabled which actually implicitly calls viewDidLoad method. Is there an elegant way to force ViewControllers viewDidLoad method to fire before it should naturally (when window is key and presented)? You can just call [viewController view]; . The documentation for UIViewController explains how the view

My viewDidLoad in a view controller is called twice. Once by [UIViewController View] and a second time by [UINib instanciateWithOwner:Options] . Why is this happening? Can it be prevented? Joe Any code you put inside of viewDidLoad should be able to run multiple times with out any issues. If you have code that only needs to run once for your controller use -awakeFromNib . The reason is because the view of the view controller can be unloaded and loaded multiple times. The code inside of viewDidLoad should only modify the UI to reflect the current state. Now that I got that out of the way, your

It is my understanding that awakeFromNib will always be called before viewDidLoad. So I have a subclass of a UITableViewController, which is unarchived from a xib file. I defined these two methods inside: - (void)awakeFromNib { [super awakeFromNib]; NSLog(@"awake from nib"); } - (void)viewDidLoad { [super viewDidLoad]; NSLog(@"view did load"); } what happens is that "view did load" shows up before "awake from nib" in the console. I tried to use a breakpoint at [super awakeFromNib], and repeatedly hit F7 (Step Into), and to my surprise, it stepped into -(void)viewDidLoad BEFORE going to the

I've got a question regarding the two mentioned methods, since in my tests I don´t make clear the order they are called. I thought that, firstly, viewDidLoad is called when the viewController is loaded for first time (as the name indicates), and inmediately after the init method. Then, I thought that once viewDidLoad returns, viewWillAppear is called. If you display another viewController, and then you return to this one, then it should be already loaded and only viewWillAppear will be called. However, while developing I make the impression that there is no order when calling viewDidLoad and
