I have a memory leak while using NSFetchedResultsController objectAtIndex:
The stack frame is as follow:

From this stack frame, it looks like the object accessed with objectAtIndex get leaked.
However, when I leave the controller, its dealloc method get called. In this method, all the objects fetched by the fetchedresultscontroller are turned into fault since I use [NSManagedObjectContext refreshObject:mergeChange].
To be complete in my description, below is the code where the leaking object is created:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
Page* page = [[self fetchedResultsController] objectAtIndexPath:indexPath];
UIImage* thumbnail = [page getThumbnail];
[[self managedObjectContext] refreshObject:page.image mergeChanges:NO];
CGFloat height = [PageCell cellImageSize:thumbnail].height + 20;
return height;
}
Any hint would be appreciated,
Thanks!
Check the code where you get the UIImage. The leak is most likely there. Where it is exactly depends on how you create the image object.
Barring more evidence, that looks more like a leak in the bowels of Core Data. File a bug.

I am trying to implement a tab bar controller, navigation controller and tableview into an application I'm working on but I am getting a SIGABRT error each time I try to run it and I don't know why and it is rather puzzling me. Below is the code that the console is referencing to (I believe):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Set up the cell...
NSString *cellValue = [listOfCoffees objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
return cell;
}
...and below is the console:

Any help would be greatly appreciated.
I'm quite sure the actual problem is somewhere else in the code, my guess would be you are using some string variable (possibly selectedCoffee ?) in place of the tableView's delegate.
The error is in the tableview delegate/datasource. CellForRowAtIndexPath is called by the tableview to query it's UITableViewCell object. Check your delegate/datasource connection.
Set a breakpoint and look where the app crash. Then we could help more.
I have a TTSplitViewController in which I am trying to show a UITabBarController at the left pane, via the code:
#implementation SplitAppController
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil {
if ((self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil])) {
[self setupURLRouting];
}
return self;
}
- (void)setupURLRouting {
[self routePrimaryNavigator];
[self routeDetailsNavigator];
}
- (void)routePrimaryNavigator {
TTURLMap* map = self.primaryNavigator.URLMap;
// Forward all unhandled URL actions to the right navigator.
[map from: #"*" toObject: self selector: #selector(willOpenUrlPath:)];
[map from:#"tt://primary" toViewController:[RootViewController class]];
}
RootViewController here is a UITabBarController. However, I am getting the following error:

How do I fix this?
Seems like your code is expecting RootViewController to be a subclass of UINavigationController.
If you didn't write that code, you can make a UINavigationController subclass, and initialize it with your tab bar controller as a root view controller, and hide the navigation bar, I think this would give the results you are looking for.
EmilioPelaez is quite right, I just succeeded with a similar solution like this, and it works!
#implementation MainViewController
- (id)initWithNavigatorURL:(NSURL *)URL query:(NSDictionary *)query {
MainTabBarController *mainTabBarController = [[MainTabBarController alloc] init];
[mainTabBarController setTabURLs:[NSArray arrayWithObjects:
#"tt://firstLink",
#"tt://secondLink",
nil]];
self = [super initWithRootViewController:mainTabBarController];
[mainTabBarController release];
self.navigationBarHidden = YES;
return self;
}
#end
I found another way to make it work (and maybe the better way that reduce code complexity):
inherit UITabBarController with this additional method:
- (UIViewController *)topViewController {
return self;
}
It works perfectly.
is this right
[map from:#"tt://primary" toViewController:[RootViewController class]];
my suggestion is
[map from:#"tt://primary" toViewController:RootViewControllerobject];
Hell All,
I am new to iPhone and struggling with following problem.
When i remove scroll view with following statement my appli crashes.
[scrollView removeFromSuperview];
I am adding uiscrollview with following line.
[self.view addSubview:scrollView];
Hereis the log.

Any Idea ?
Thank you.
Check whether it has a superview before removing from superview;
if([scrollView superview]!=nil){
[scrollView removeFromSuperview];
}
Try this code
for(UIView *view in self.view.subviews)
{
if([view isMemberOfClass:[UIScrollView class]])
{
[scrollview removeFromSuperView];
}
}
Try this code. It's tested.
NSArray *subviews = [[NSArray alloc] initWithArray:self.view.subviews];
for(UIScrollView *subview in subviews) {
[subview removeFromSuperView];
}
[subviews release];
but be carefull it removes all ScrollViews present in your self.view
IBOutlet UITextView *readme;
[super viewDidLoad];
NSString *string = [[NSString alloc] initWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"README" ofType:#"txt"] encoding:NSUTF8StringEncoding error:nil];
readme.text = string;
This part of code makes EXC_BAD_ACCESS in UIApplicationMain when i change tab item to other. without this code everything working fine.
Any ideas?
NSZombieEnabled = YES, but point is leave on same position while i press next step.
IBOutlet is connected as reference outlet to readme. This is a stack.

SOLUTION
UIImage *imageForEvents = [UIImage imageWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"events" ofType:#"png"]];
UITabBarItem *eventsBar = [[UITabBarItem alloc] initWithTitle:#"Events" image:imageForEvents tag:0];
events.tabBarItem = eventsBar;
[eventsBar release];
this peace of code was create in table view controller area. after i was change it to appdelegate, error was go out.
strange that debug don't show appropriate line of code.
Set NSZombieEnabled to check which object is responsible for EXC_BAD_ACCESS.
Are you sure readme IBOutlet is exactly connected in Interface Builder?
NSLog(#"className of readme is \"%#\".", [readme className]);
BTW, UITextView text property has copy attribute, autoreleased string would be nice.
NSString *string = [NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:#"README" ofType:#"txt"] encoding:NSUTF8StringEncoding error:nil];
The code you have posted should not cause EXC_BAD_ACCESS. Since EXC_BAD_ACCESS is what happens when you try to send a message to a class that has deallocated, I would look in your app for where you either release something and do not set the pointer to nil or if you should be retaining something and are not doing so.
Recently I have finished my first Iphone app and it works grate.... except for when i did a intense session using instruments to find leaks after awhile with no leaks, all of a sudden get about 1.3Kb worth. In the stack trace they all point to the exact line that I release a UIViewControler on after pushing it to the Navigation controller (Ill post this code a bit further down). The Leak seem to happen after a few time navagating through the ViewControlers and back again. I know this is a very generally question but I hope someone could point me in the right direction. I have spent a few days trying to solve this and it is starting to dive me crazy!
My app is a Navigation based one, here is how it works in a nutshell:
Starts with a UIViewControler which when a button is pressed goes to another UIViewControler containing a TableView.
From here depending on the contents of the array that populates the TableView it could go to a UIViewControler containing a PickerView then to the last UIViewControler or just go straight to the last UIViewControler bypassing the one with the PickerView.
Here is the code that the stack trace says the Leak is on:
SoundConfiger *third = [[SoundConfiger alloc] initWithNibName:#"SoundConfiger" bundle:[NSBundle mainBundle]];
[third setTitle:#"Sound Link"];
third.myData = myData;
third.selectedRow = row;
third.currentChoise = nil;
[self.navigationController pushViewController:third animated:YES];
[third release]; <---- Instruments says the leak is here on this line.
Shouldn't the NavigationController be responsible for this UIViewcontroler now? I have not called retain on third anywhere else and it only exists in this function.
I have a Bunch of Leaks from UIkit and QuartsZone. I have a screen shot bellow of some of them, in the stack traces all point to the same snippet of code, in the same function, in the same object as stated above at some point in the trace:

Thanks for your help in advance, I am hope I am just doing something silly and I need a fresh set of eyes to see it. Let me know If you need more info.
Well I am a Tool :)
I was not handeling the IBOutlets correctly in each viewControler.
I was not declaring each IBOutlet using #property with a retain, using "self.someLabel = nil" (to release and set to the IBOutlets to nil) in the viewDidUnload method for a memory warning and then finally releasing in in dealloc.
thus tool. lol
What I was doing was declaring was "IBOutlet UILabel *someLabel;" in the header with no #property and this was causing the leaks seen above, they don't happen right away it takes a while and when they do the stack trace and every thing dose not help to much.
They only way I found what was leaking was striping everything out of my app and I mean everything until the leak went away.
Thanks for your help Ishu Gupta, I am glad we had a outcome.
Here are the relevant link to show how to do IBOutlets correctly: What happens if I don't retain IBOutlet?
SoundConfiger *third = [[[SoundConfiger alloc] initWithNibName:#"SoundConfiger" bundle:[NSBundle mainBundle]] autorelease];
and remove
[third release]; this line.
You can fix only those leaks which comes because of your code(forget release any object or some wrong things). But some time you get extra leaks these are present in iphone sdk. Actully some of functions or properties of iPhone having leaks.so these can be fixed only when you change the use of these.
And one thing more 1.3 KB leak is not bad if it will not be increase with app operations.
