Hi, I have the weirdest problem, I setup a UIWebView in the viewDidLoad section of my viewController and for some reaosn it keeps on looping through the setup : - (void)loadView { UIWebView *webViewer = [[UIWebView alloc] initWithFrame:CGRectMake(0, 0, 320, 430)]; webViewer.delegate = self; webViewer.scalesPageToFit = YES; w...
hello. someone could tell me please why when launch my app in the second time (after pressing the home button) the method viewDidLoad is not being called. thanx. ...
Bottom line is, I've been working on an app, and it seems that if I place a UIAlert in viewDidLoad, it gets called twice (from a delegate method of UIImagePickerController). If I put it in viewDidAppear, it gets called once. I've looked through documentation but it just confuses me. Can someone explain it to me? Thank you. ...
I have an app with a tab bar that has a few tabs with user-generated content. When each view controller loads, the viewDidLoad method makes HTTP requests to a server to fetch data, then populates its view correspondingly. Once all the data is loaded, however, the view remains the same (unless the view controller is unloaded and reloaded)...
I noticed that when building then running viewDidLoad only gets called once. If you press the home button and re-enter the application, viewDidLoad does not execute again. Another thing I noticed is that when you re-enter an application it starts off right where you left off. Is this the same behavior as in older SDKs? Does this mean t...

I am using the iPhone toolchain on Linux and so I have no Interface Builder. So how could I layout my view in my ViewController subclass? For example, I want a UITextView in the middle of the screen? Should I do this in the loadView or viewDidLoad. Do I also have to set the view for the ViewController subclass to itself? ...
Is it safe to assume that an attribute, namely fetchedResultsController, of chatViewController, an instance of a subclass of UITableViewController, is always nil when viewDidLoad is called, assuming that it's set to nil in viewDidUnload? Phew! If that's the case, then I see no immediate need to redefine the accessor function like in the...
Hi, I know that ViewDidUnload may be called if there is a problem in an app such as a memory warning. When that view is loaded later, ViewDidLoad is called again. If ViewDidUnload is not called, but a view that was previously shown is moved aside (like in a UINavigationBar), is ViewDidLoad called again? What can be done if one does no...
I have a tab bar application which loads a UITableView when one of it's buttons are selected. It seems to load the view controller however it doesn't seem to be populating the data. I have tried setting the cell.text = @"cell" (while setting the number of rows > 0) and an NSLog in the CellForRowAtIndexPath proves that in fact the functio...
