  • Can get members, but not count of NSMutableArray

    - by Curyous
    I'm filling an NSMutableArray from a CoreData call. I can get the first object, but when I try to get the count, the app crashes with Program received signal: “EXC_BAD_ACCESS”. How can I get the count? Here's the relevant code - I've put a comment on the line where it crashes. - (void)viewDidLoad { [super viewDidLoad]; managedObjectContext = [[MySingleton sharedInstance] managedObjectContext]; if (managedObjectContext != nil) { charactersRequest = [[NSFetchRequest alloc] init]; charactersEntity = [NSEntityDescription entityForName:@"Character" inManagedObjectContext:managedObjectContext]; [charactersEntity retain]; [charactersRequest setEntity:charactersEntity]; [charactersRequest retain]; NSError *error; characters = [[managedObjectContext executeFetchRequest:charactersRequest error:&error] mutableCopy]; if (characters == nil) { NSLog(@"Did not get results for characters: %@", error.localizedDescription); } else { [characters retain]; NSLog(@"Found some character(s)."); Character* character = (Character *)[characters objectAtIndex:0]; NSLog(@"Name of first one: %@", character.name); NSLog(@"Found %@ character(s).", characters.count); // Crashes on this line with - Program received signal: “EXC_BAD_ACCESS”. } } } And previous declarations from the header file: @interface CrowdViewController : UITableViewController { NSManagedObjectContext *managedObjectContext; NSFetchRequest *charactersRequest; NSEntityDescription *charactersEntity; NSMutableArray *characters; } I'm a bit perplexed and would really appreciate finding out what is going on.

  • Not receiving touchesEnded/Moved/Cancelled after adding subView

    - by Sam
    Title more or less says it all. In response to a touchesBegan event, my UIViewController recolours itself and adds some subviews. It never receives the touchesEnded. I guess because the added subviews are somehow intercepting the event. I tried calling resignFirstResponder on the subviews to no avail. The code works fine when I don't add the child views and the touch events are called as normal. Any ideas? Thanks

  • My UITableView has duplicated rows

    - by Mark
    Im not sure why, but my UITableView, which isnt anything fancy, is showing repeating rows when it shouldnt be. It seems that the rows that get added when the user scrolls (i.e. the rows that are off the screen to start with) are getting the data for the wrong row index. Its almost like when a new cell is de-queued, it's using a cell that 'was' used, but wasn't cleaned up correctly. Do you need to 'clean up' cells that are de-queue so that new cells dont use cells that are already created? my code is as below: - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *CustomCellIdentifier = @"CustomCellIdentifier"; MyDayCell *cell = (MyDayCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier]; if (cell == nil) { NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MyDayCell" owner:self options:nil]; for (id oneObject in nib) if ([oneObject isKindOfClass:[MyDayCell class]]) cell = (MyDayCell *)oneObject; } NSUInteger section = [indexPath section]; NSUInteger row = [indexPath row]; NSArray *thisSectionItems = (NSArray*)[self.listData objectForKey: [[NSNumber alloc] initWithInt:section]]; MyDayDetails *rowData = [thisSectionItems objectAtIndex:row]; //setup my cells data here... return cell; } Is there anything wrong with this code? has anyone seen anything like this before?

  • Why do I not get low memory issues until images are draw on the screen?

    - by maxpower
    I am able to load over 200 UIImage objects into a NSMutableDictionary without any memorry warning issues. When I start displaying them on the screen (after about showing 10-20 images) I get low memory warnings and an eventual crash. Only about 8 images are displayed at anyone time. Does it take additional memory to actually draw a UIImage on the screen? No memory leaks are showing up and i've reviewed code for leaks many many times.

  • MPMoviePlayerContentPreloadDidFinishNotification seems more reliable than MPMoviePlayerLoadStateDidChangeNotification

    - by user567889
    I am streaming small movies (1-3MB) off my website into my app. I have a slicehost webserver, I think it's a "500MB slice". Not sure off the top of my head how this translates to bandwidth, but I can figure that out later. My experience with MPMoviePlayerLoadStateDidChangeNotification is not very good. I get much more reliable results with the old MPMoviePlayerContentPreloadDidFinishNotification If I get a MPMoviePlayerContentPreloadDidFinishNotification, the movie will play without stuttering, but if I use MPMoviePlayerLoadStateDidChangeNotification, the movie frequently stalls. I'm not sure which load state to check for: enum { MPMovieLoadStateUnknown = 0, MPMovieLoadStatePlayable = 1 << 0, MPMovieLoadStatePlaythroughOK = 1 << 1, MPMovieLoadStateStalled = 1 << 2, }; MPMovieLoadStatePlaythroughOK seems to be what I want (based on the description in the documentation): MPMovieLoadStatePlaythroughOK Enough data has been buffered for playback to continue uninterrupted. Available in iOS 3.2 and later. but that load state NEVER gets set to this in my app. Am I missing something? Is there a better way to do this?

  • Custom UITableView headerView disappears after memory warning

    - by psychotik
    I have a UITableViewController. I create a custom headerView for it's tableView in the loadView method like so: (void)loadView { [super loadView]; UIView* containerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, width, height * 2 )]; containerView.tag = 'cont'; containerView.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleTopMargin; UIButton* button = [UIButton buttonWithType:UIButtonTypeCustom]; button.frame = CGRectMake(padding, height, width, height); ... //configure UIButton and events UIImageView* imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"] highlightedImage:[UIImage imageNamed:@"highlight.png"]]; imageView.frame = CGRectMake(0, 0, width, height ); ... //configure UIImageView [containerView addSubview:button]; [containerView addSubview:imageView]; self.tableView.tableHeaderView = containerView; [imageView release]; [containerView release]; } None of the other methods (viewDidLoad/Unload, etc) are overloaded. This controller is hosted in a tab. When I switch to another tab and simulate a memory warning, and then come back to this tab, my UITableView is missing my custon header. All the rows/section are visible as I would expect. Putting a BP in the loadView code above, I see it being invoked when I switch back to the tab after the memory warning, and yet I can't actually see the header. Any ideas about what I'm missing here? EDIT: This happens on the device and the simulator. On the device, I just let a memory warning occur by opening a bunch of different apps while mine is in the background.

  • UIPickerView didSelectRow delay

    - by Rob Bonner
    Hello all, I have a UIPickerView implemented in one of my pages that depends on the didSelectRow delegate method. An odd behavior I have noticed is when the user moves a wheel and leaves it between selections, then the wheel will move very slowly to the closest selection. The didSelectRow event will not fire until this is complete, sometimes 3 seconds later. Is there a way to speed this up, or detect when the wheel is being moved, so I can freeze my interface during this time?

  • Integer Extensions - 1st, 2nd, 3rd etc [closed]

    - by David Schiefer
    Possible Duplicate: NSNumberFormatter and ‘th’ ‘st’ ‘nd’ ‘rd’ (ordinal) number endings Hello, I'm building an application that downloads player ranks and displays them. So say for example, you're 3rd out of all the players, I inserted a condition that will display it as 3rd, not 3th and i did the same for 2nd and 1st. When getting to higher ranks though, such as 2883rd, it'll display 2883th (for obvious reasons) My question is, how can I get it to reformat the number to XXX1st, XXX2nd, XXX3rd etc? To show what I mean, here's how I format my number to add a "rd" if it's 3 if ([[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]] isEqualToString:@"3"]) { NSString*badge = [NSString stringWithFormat:@"%@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; NSString*scoreText = [NSString stringWithFormat:@"ROC Server Rank: %@rd",[container stringByTrimmingCharactersInSet:[NSCharacterSet whitespaceAndNewlineCharacterSet]]]; profile.badgeValue = badge; rank.text = scoreText; } I can't do this for every number up to 2000 (there are 2000 ranks in total) - what can I do to solve this problem?

  • Releasing Autoreleasepool crashes on iOS 4.0 (and only on 4.0)

    - by samsam
    Hi there. I'm wondering what could cause this. I have several methods in my code that i call using performSelectorInBackground. Within each of these methods i have an Autoreleasepool that is being alloced/initialized at the beginning and released at the end of the method. this perfectly works on iOS 3.1.3 / 3.2 / 4.2 / 4.2.1 but it fataly crashes on iOS 4.0 with a EXC_BAD_ACCESS Exception that happens after calling [myPool release]. After I noticed this strange behaviour I was thinking about rewriting portions of my code and to make my app "less parallel" in case that the client os is 4.0. After I did that, the next point where the app crashed was within the ReachabilityCallback-Method from Apples Reachability "Framework". well, now I'm not quite sure what to do. The things i do within my threaded methods is pretty simple xml parsing (no cocoa calls or stuff that would affect the UI). After each method finishes it posts a notification which the coordinating-thread listens to and once all the parallelized methods have finished, the coordinating thread calls viewcontrollers etc... I have absolutely no clue what could cause this weird behaviour. Especially because Apples Code fails as well. any help is greatly appreciated! thanks, sam

  • IOS : BAD ACCESS when trying to add a new Entity object

    - by Maverick447
    So i'm using coredata to model my relationships . This is the model in brief Type A can have one or more types of type B Type B has a inverse relationship of being associated with one of type A Type B can have one or more types of type C Type C has a inverse relationship of being associated with one of type B From a UI standpoint , I have a Navigation controller with controllers that successively sets up the first A object (VC-1) , then another viewcontroller (VC-2) creates a B object ( I pass in the A object to this controller) and the B object is added to the A object . Similarly the same thing happens with B and C . The third Viewcontroller (VC3) first creates a C object and assigns it to the passed B Object . Also between these viewcontrollers the managedObjectCOntext is also passed . SO my use case is such that while viewcontroller (VC-3) is the top controller a button action will keep creating multiple objects of type C and add them to the same type B object that was passed . Also as part of this function I save the managedObject context after saving each type C . e.g. code in viewcontroller 3 - (void) SaveNewTypeC { TypeC *newtypeC = (Question*)[NSEntityDescription insertNewObjectForEntityForName:@"TypeC" inManagedObjectContext:managedObjectContext]; [newtypeC setProp1:] ; [newtypeC setProp2:] .. .. **[typeBObject addTypeCInTypeBObject:newtypeC];** [section setTotalCObjectCount:[ NSNumber numberWithInt:typeCIndex++]]; NSError *error = nil; if (![managedObjectContext save:&error]) { // Handle error NSLog(@"Unresolved error %@, %@, %@", error, [error userInfo],[error localizedDescription]); exit(-1); // Fail } [newtypeC release]; } - (IBAction)selectedNewButton:(id)sender { [self SaveNewTypeC]; [self startRepeatingTimer]; } The BAD ACCESS seems to appear when the bold line above executes Relating to some HashValue . Any clues on resolving this would be helpful .

  • Where is the best place to run initialization code for a UITabBarController?

    - by bobobobo
    I have a UITabBarController in my application. I have to perform some customization to the NIB file using code the first time a view embedded in that UITabBarController gets loaded. When applicationDidFinishLaunching occurs, the UITabBarController's views apparently are not loaded -- if I try to modify the view controllers inside a tab bar that the tab bar is to load in applicationDidFinishLaunching, then those changes are ignored. I'm assuming this is because the tab bar didn't finish loading yet. So, I need a good place to put code that will run immediately after a tabbar is fully ready -- i.e. after it has loaded all the views from their respective nib files. I'm finding the only place I can do this is to track the first time viewDidAppear on each individual view controller. Note I can't use viewWillAppear because I need the value of tabBarController.selectedIndex to be accurate, and it is only actually updated after viewDidAppear gets fired, not when viewWillAppear gets fired.
