viewdidload

This seems to be a fairly common problem, but the solutions that I have looked at do not solve the error. I am trying to read an NSMutableArray from a JSON file. Many of the suggestions I have seen involve using mutableCopy or [NSMutableArray arrayWithArray:] but both of these solutions do not fix the problem when using the call replaceObjectAtIndex:withObject: seen below. Please let me know if you have any advice on how to solve this problem. EDIT: I would also like to add that the inventory list is an NSMutableArray of NSMutableArray objects. The exact error reads: Terminating app due to

I have viewDidLoad (of next tableView) being called before didSelectRowAtIndexPath (of current tableView ). I am using a 'singleton' to hold my model and up to now this has been working quite well. I am trying to pass on the row selected in the current table in didSelectRowAtIndexPath to the destination tableview (they are linked by a segue in storyboard) by setting by the variable in didSelectRowAtIndexPath . However the viewDidLoad of the destination tableview is called before I can set the row number. didSelectRowAtIndexPath is called later but by then I have set up my data (wrongly) for

I've made an iPad application, It works fine when I load my application in portrait mode for first time, but when I load my application in landscape mode for the first time, it takes the coordinates of portrait mode only, because inside my didLoad method I give coordinates of portrait mode only. Now need to give coordinates of landscape mode inside my didLoad method. I tried this, inside my didLoad method if (interfaceOrientation == UIInterfacePortraitmode || interfaceOrientation == UIInterfaceUpsideDown) { // do this.... } else { // do this.... } but I am unable to write the condition for the

Head's up: This question is related to the recent deprecation of viewDidUnload . I have seen "great" and logical answers around this topic, but apparently they were proven wrong . Proceed with caution, this topic is very confusing as you see. From Apple's Docs: However, the system automatically releases these expensive resources when the view is not attached to a window. The remaining memory used by most views is small enough that it is not worth it for the system to automatically purge and recreate the view hierarchy. So... Can I safely assume in iOS 6 that, as long as I don't explicitly set

I've been searching around but unfortunately have had no luck. My app requires the user to sign in/sign up the first time he or she launches the app. I know how to determine first launch (using NSUserDefaults) but whenever I try to present the modal containing the sign in/ sign up controls, nothing happens. Here's what I have: -(void)viewDidLoad { [self showLogin]; [super viewDidLoad]; } -(void)showLogin { FlipsideViewController *controller = [[FlipsideViewController alloc] initWithNibName:@"AccountView" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle =

I have an iOS app in which I need to know when a new view is completely visible on-screen; that is, when Autolayout has finished its calculations and the view has finished drawing. ViewDidAppear seems to fire well before the view is completely visible. If I turn off Autolayout, the timing seems to line up as far as human perception goes, but I need to use Autolayout in this project (so this isn't a solution...just a test). Is there any method that fires when Autolayout is done calculating? Or another method that fires when the view is ACTUALLY visible (since ViewDidAppear doesn't work for this
