  • App Crashes on Opening - PROBLEM

    - by Guest
    I have an app that keeps crashing as soon as it starts. Not sure why. I have image views and buttons in the main xib file. The main xib file is not mainwindow, it is firstview, so i changed it in the plist to the firstview. There may be something wrong with the xib file for firstview but it only has buttons and images and a view in the back. There are no warnings or errors when I run it, just Debugging Terminated when it crashes. PLEASE HELP

  • Time in "Upload Received"

    - by rpeck1682
    I uploaded an app to itunes connect yesterday afternoon. It has been in the "Upload Received" stage ever since then. I uploaded a different app today, it was in that stage for only five minutes. This is the first time I've submitted since the new, more detailed status updates were present. I'm just wondering if the app sitting there in that state for so long seems like something to be concerned about. I'm guessing by staying in that state that it isn't being put on the review queue. Anyways, has anyone else had a similar experience?

  • Why aren't Admob click callback delegate methods not getting called?

    - by executor21
    I'm integrating the latest version of the admob sdk (version 20100412) into my app. The ads get displayed, but I need the app to make some changes when an ad is clicked and admob displays a full-screen browser. However, none of the callback methods (willPresentFullScreenModal, didPresentFullScreenModal, willDismissFullScreenModal, and didDismissFullScreenModal) are called, even though other delegate methods are. Why aren't these callbacks being made? They were in the previous versions of the SDK, and the sample app doesn't use them, so it's no help.

  • UITextView refuses to change its color

    - by Friendlydeveloper
    Hello, in some cases things you'd expect to solve within a sec turn out to become a lifetime adventure. This is one of these cases :) All I wanted to do, is simply change the text color of one of my UITextViews. So far I tried: UIColor *myColor = [UIColor colorWithHue:38 saturation:98 brightness:100 alpha:1.0]; [myTextView setTextColor:myColor]; OR UIColor *myColor = [UIColor colorWithPatternImage:[UIImage imageNamed:@"colorImage.png"]]; [myTextView setTextColor:myColor]; Both seem to work fine for UILabels, but fail for UITextView elements. When I try [UIColor colorWithHue... I only get a reddish kinda color, no matter what values I choose (except values for black and white. They work). The colorWithPatternImage does not change textColor at all. Strange isn't it? I obviously must be missing something. Help is very much appreciated. Thanks in advance.

  • Are there concurrency problems when using -performSelector:withObject:afterDelay: ?

    - by mystify
    For example, I often use this: [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:someDelay]; Now, lets say I call this 10 times to perform at the exact same delay, like: [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; [self performSelector:@selector(doSomethingAfterDelay:) withObject:someObject afterDelay:2.0]; - (void)doSomethingAfterDelay:(id)someObject { /* access an array, read stuff, write stuff, do different things that would suffer in multithreaded environments .... all operations are nonatomic! */ } I have observed pretty strange behavior when doing things like this. For my understanding, this method schedules a timer to fire on the current thread, so in this case the main thread. But since it doesn't create new threads, it actually should not be possible to run into concurrency problems, right?

  • Objective-C retain clarification

    - by Maverick
    I'm looking at this code: NSMutableArray *controllers = [[NSMutableArray alloc] init]; for (unsigned i = 0; i < kNumberOfPages; i++) { [controllers addObject:[NSNull null]]; } self.viewControllers = controllers; [controllers release]; Later on... - (void)dealloc { [viewControllers release]; ... } I see that self.viewControllers and controllers now point to the same allocated memory (of type NSMutableArray *), but when I call [controllers release] isn't self.viewControllers released as well, or is setting self.viewControllers = controllers automatically retains that memory?

  • Obj-C: Creating an object with a String name

    - by FnGreg7
    Hey all. I know this sounds simple, but I can't find a way to do it. I have a method in Obj-C that takes in a NSString and then should create a new class with the String as its title. -(DataModel *)createDataModel:(NSString *)dataModel_name { DataModel *[initWithString:dataModel_name] = [[DataModel alloc] init]; } I know I have some problems in this. For starters, I don't know how to define a return on an object whose name could change. Second, I know this doesn't compile considering the initWithString method is wrong. I just don't know what to do or what method to use so that I can create this DataModel object with the specified name...

  • How to handle UIPickerView with two data sources?

    - by devb0yax

So, for example, when first segment is clicked, the picker will display person's name. Then, when second segment is clicked, picker will display place's name. Thanks

  • iOS sdk question: how do I cast a UIView to a UIImage View (alternativly how do I get a UIImageView from a GestureRecognzer?)

    - by user439299
    Desired end result: user taps a UIImageView and the image changes to another image (a subsequent tap returns the image to the original state) Problem: I add a (unique) selector to a bunch of UIImageViews (in an array) and point the action at the same function - let's call this function imageTapped: for now. Here is my code so far: -(void)imageTapped:(UITapGestureRecognizer *)tapGesture { UIImageView *view = tapGesture.view; // rest of code... } This code actually works fine but gets a warning when I run it: "Incompatible objective c types initilizing 'struct UIView *', expected 'struct UIImageView *' Any way to get rid of this? Not sure how casting works in objective c... primitive types seem to work fine such as (int)someFloat works fine but (UIImageView)someUiView doesn't work. Like I said, code works alright when I run it but would like to get ride of the compiler warning. Any help would be awesome.... I am very new to objective c (or any non java language for that matter) so be gentle. Thanks in advance.

  • Utility App with Navigation Controller and Table View on FlipSide.

    - by wdt
    Hi All. I am relatively new to the whole MVC way of looking at things. I have an application that is based on the "Utility" Application template. Everything in the MainView and FlipsideView is working great but now I need to add a TableView and Navigation Controller to the flipside. Without the navigation bar being on the MainView. So only once the user has tapped the info light button will the nav bar display on the flipside with a table view. I have been able to impliment the Table View on the side and populate it with data from an array. I am now struggling to link in a navigation controller so that the tableview can become interactive. When I place the nav bar code into the app delegate it appears on the MainView and not the flipside view. Where do I place the navigation bar code so that it will display on the flipsideview. I cannt seem to get the code in the right place. Also I am not sure I have the right code, do I put the UINavigationController code in the FlipSideViewController.m ? I am not grasping the concept of the naivgation controller fully I think . . . Here is the code to bring up the FlipView - (IBAction)showInfo { TableViewController *controller = [[TableViewController alloc] initWithNibName:@"TableViewController" bundle:nil]; controller.delegate = self; controller.modalTransitionStyle = UIModalTransitionStyleFlipHorizontal; [self presentModalViewController:controller animated:YES]; [controller release]; } Now I need to get the TableViewController to have a navigation controller and a table view Thanks in advance.

  • UIActionsSheet text shadow problem

    - by AlexVogel
    I have a problem with the text shadow of the UIActionSheet buttons. At iOS 4.0.2 long string were truncated automatically. No at iOS 4.2 these texts are presented with a smaller font. But now the offset of the shadow is corrupted and to big. Is there a possibility to change/remove the text shadow of the UIActionSheet. EDIT: I'm building the UIActionSheet not with initWithTitle:, but with the normal init and sets all needed properties afterwards because the number of possible buttons is dynamic and the texts cannot be change. I've tested it with initWithTitle: and got the same results.

  • AND NSPedicate on Core Data relationships

    - by jesse001
    I'm having trouble compounding NSPredicate with AND, although using OR works fine. Imagine 2 entities, Doctor and Patient. Doctors can have many patients and patients many doctors. I want to find doctors that, say, have both person1 and person2 as patients. I expected this to work but it returns none. NSPredicate *predicate = [NSPredicate predicateWithFormat:@"ANY patients matches 'person1&&person2'"]; If I change && to ||, I get all doctors that have person1 or person2 as I'd expect. Thanks in advance for your help.

  • Moving UITableView row to top of list when selected

    - by Max Kilgore
    I am sure this is an easy thing to do. I am very new to objective C (picked up a job the boss was going to outsource) and could use all the help I can get. Just point me in the right direction here. Basically what I want to set up is this: I have a list of phone numbers that expands to as many rows as needed. I have no problem populating and the list works fine, but I would like for all of the recently selected items in the list to be more easily accessible at the top. So, whenever the user "didSelectRowAtIndexPath", I would like the row to move to the top. I just KNOW this is super simple... but I haven't found the solution yet. No hurry. I am just trying to figure things out on my own. Thanks in advance!

  • how to create a custom settings view / make cell label editable

    - by Lex
    Hi everyone, I need to create a custom settings view used within the app. The app is a mockup so it actually does have one already, it uses a UITableViewCellStyleValue1, but nothing is editable. So essentially what I would like to have is the same thing but with editable detailTextLabel (the label on the right hand side), what's the best way to do this?

  • titleForHeaderInSection is not updating Section Header information correctly

    - by Jim
    I have two tableviews where one navigates to the next. Both use more or less the same code and use the managedObjectContext and FetchedResultsController design pattern to provide the relevant data for both tables. My problem happens when I navigate from the first to the second tableview and the data has only one Section Header / Row in the tableview. The data will then not update Section Header information. It does when there is more than one row but not if there is only one row. It leaves the information from the first attempt in place. I can confirm the row data is correct so the relevant data should be being passed to the Section Header correctly but it isn't. Has anyone else come across this problem?

  • Optional Navigation Controller

    - by Kevin Sylvestre
    I have an application containing a variety of view controllers linked together in different ways (Welcome Browse Preview OR Browse Preview OR Settings Splash). The first view controller is presented modally using a navigation controller from a main controller, then the next set of view controllers are added using pop and push. This works correctly, but I need to be able to define my 'UINavigationBar' and 'UIToolbar' within interface builder, so they still work as expected if they are presented without using a navigation controller. Is this possible? Currently I get this if I try:
