viewdidload

I am using navigation controller. I have pushed two viewcontroller to navigation stack. When I am coming back to viewcontroller1 from viewcontroller2 using back button of navigation bar then viewdidload method of viewcontroller1 is called again.But as much as I know viewdidload is called only once at loading time. So why is this happening? Please tell me. Thanks!! -(void)viewDidLoad called only when view controller is loaded but if you want to call any method then you can write code in -(void)viewWillAppear this method called every time when your view is appear. About viewDidLoad viewDidLoad:

I am trying to push a ViewController programmatically into a navigation controller, And I'm using my storyboard to create it. here is my code : + (void) pushViewController:(NSString *) identifier ForItems:(NSMutableArray *) items sender:(UIViewController *) sender { GenericViewController *viewController = (GenericViewController *)[sender.storyboard instantiateViewControllerWithIdentifier:identifier]; viewController.items = [[NSMutableArray alloc] init]; [viewController.items removeAllObjects]; [viewController.items addObject:[[NSMutableArray alloc] init]]; [viewController.items[0]

I've been following this tutorial to have a Slide-Out Menu. I've added a TableViewController which will display a list of articles. For some reason the viewDidLoad is not firing. In this tutorial a SideViewController controls which controller will be displayed, in case of having a segue with identifier "showPhoto", it will load a specific image. // Set the photo if it navigates to the PhotoView if ([segue.identifier isEqualToString:@"showPhoto"]) { PhotoViewController *photoController = (PhotoViewController*)segue.destinationViewController; NSString *photoFilename = [NSString stringWithFormat:

This question already has answers here : Closed last year . Difference between viewDidLoad and viewDidAppear (2 answers) 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. A UIView object can get loaded into memory and released multiple times without ever getting added to the view stack and appearing on the display. My guess is that you have 2 references to this

I tried to add a animation to viewDidLoad and viewDidAppear, but it doesn't work: - (void)viewDidAppear:(BOOL)animated{ [UIView beginAnimations:@"transition" context:NULL]; [UIView setAnimationTransition:110 forView:self.view cache:YES]; [UIView commitAnimations]; } Why? jackbravo I had the same problem and I think I found the solution on this SO question . When viewDidAppear gets called you still don't see anything on the screen (despite the name), but you are about to. You can then use a performSelector:withDelay or an NSTimer to launch your animation. The delay can just be 0.1 and your

Problem Summary My mainVC --> second VC transtion appears to run twice. However, what's odd is that the second VC's viewDidLoad only runs once. This is the only transition in my project that has this problem. I have researched this and found load-twice issues but none are a match to my transition twice but load once scenario. Common issues, like someone having added two segues in the storyboard, do not appear in my project: In my first/root view controller (called mainVC) I programmatically add an edge pan gesture in the viewDidLoad: let panLeftEdgeGesture_MainVC =

I've read several posts on this issue but none of them solved my problem. I'm coding an app where I have to click on a button ("Prepare") to go to the following ViewController. When the button is clicked, it also passes data between the two view controller. The problem is, when I click the button, the following ViewController loads twice. Thus, if I want to go back I have to go back through two same ViewController. I've checked the segue, the class names and files names but nothing fixes it. I've also created a new project and rewritten all the code from the beginning but in the end, it still

i initialize tables, data etc in my main ViewController. For more settings, i want to call another Viewcontroller with: DateChangeController *theController = [self.storyboard instantiateViewControllerWithIdentifier:@"dateChangeController"]; [self presentViewController:theController animated:YES completion:^{NSLog(@"View controller presented.");}]; And some clicks later i return with a segue (custom:) NSLog(@"Scroll to Ticket"); [self.sourceViewController presentModalViewController:self.destinationViewController animated:YES]; My Problem: After returning to my main ViewController, viewDidLoad
