Unable to trace an error - iphone

I'm trying to add an ad package on an app. I've done it on another project, it worked. But here I'm having a mysterious error, that never happened before. Could you help me to trace it ?
Could you help me to trace this error ?

Here is the code that create the ad:

//Intialize the SmartAdServerView object. This example is for a banner on the iPhone, you can specify any frame you want.
//By convention, banners have a ratio aspect of 6:1 in portrait mode, so if you have borders in your application, you should adapt the ad's height. The creative will be adapted to your view's frame, but it will look better if they have the same size.
//The iPad recommended height, with a 6:1 ratio is 128 pixels
SmartAdServerView *banner = [[SmartAdServerView alloc] initWithFrame:CGRectMake(.0,315.0,320.0,53.0) loader:SmartAdServerViewLoaderActivityIndicatorStyleWhite];
//Set an auto-resizing mask, for the view to adapt it's size when it's superview is resized (after a rotation for example). Typically a banner keep it's height and adapt it's width.
banner.autoresizingMask = UIViewAutoresizingFlexibleWidth;
//Set the banner to stay in place, so it won't be removed automatically.
banner.unlimited = YES;
//Set your ad's delegate, which will be the presentator of ad's modal view to the user, and will be notified of significative events
banner.delegate = self;
NSLog(#"set the delegate.");
NSLog(#"the delegate is = %#", [[banner delegate] class]);
//Load the ad with your settings
//The siteId can be a string in some rare cases, this is why you have to pass an NSString
//One ad per page of your application should have the "YES" for the "master" argument, and the other should have "NO", this is for page view counting.
//[banner loadFormatId:12345 pageId:#"98765" master:YES target:nil];
//Display the ad to the user, here we assume that we are in a UIViewController
[self.view addSubview:banner];
self.myAd = banner;

}
Thanks a lot.

I contacted the ad operator. Thanks you all.

Search for initWithPageId:formatId:master:target:creator:request:requestDelegate: method in your code. You are calling it for an object that does not recognize it.

Using UIAppearance with a subclass of UIBarButtonItem is causing unrecognized selector being sent to UINavigationButton

TL&DR;
Setting a custom property of a subclass of UIBarButtonItem using UIAppearance proxy is causing the "unrecognized selector" exception, beause the setter is probably being forwarded by UIAppearance to UINavigationButton, not the bar button itself.
SDK overview
I am using iOS 7 Beta 5 SDK with Xcode 5 DP5. But please, don't tell me that it is under NDA, because I do not discuss any new features or new classes in this question. I inform you of my SDK, because it can be found out that it's just a bug in the beta software.
What I did
I subclassed a UIBarButtonItem and created a custom property in the header file:
#property (nonatomic, strong) NSString *mySubclassedProperty UI_APPEARANCE_SELECTOR;
My setter and getter look like this:
- (void)setMySubclassedProperty:(NSString *)mySubclassedProperty {
_mySubclassedProperty = mySubclassedProperty;
NSLog(#"%p %s %#", self, __PRETTY_FUNCTION__, mySubclassedProperty);
}
Nothing special, huh? But it doesn't work with UIAppearance at all. When I try to set the default appearance in my application's delegate, it gives me no error, no warning, whatsoever.
[[AKBarButtonItem appearance] setMySubclassedProperty:#"GLOBALLY ASSIGNED"];
The crash
It seems to be working like a charm, except of the fact that it crashes when I try to set an instance of AKBarButtonItem to self.navigationItem.rightBarButtonItem:
self.navigationItem.rightBarButtonItem = [[AKBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemAction target:nil action:nil];
The backtrace looks like this:
2013-08-13 14:30:08.551 UIBarButtonItem Subclass Demo[1512:a0b] -[UINavigationButton setMySubclassedProperty:]: unrecognized selector sent to instance 0x8c42710

libc++abi.dylib: terminating with uncaught exception of type NSException
After some examination I strangly realized that the setMySubclassedProperty: message is sent to UINavigationButton (which is a private subclass of UIButton used in navigation bars, toolbars and search bars). I set the button in frame 26 and the UIAppearance magic is executed in frame 10.
In iOS 6, the issue exists but a different message is sent to UINavigationButton:

Deduction
My first thought was: "UIAppearance forwards the setter to AKBarButtonItem and then it crashes". But does it? In an article by Peter Steinberger I found out that Apple is using a special subclass of _UIAppearance for bar items which is called _UIBarItemAppearance. I wanted to confirm that and set a symbolic breakpoint on -[_UIBarItemAppearance forwardInvocation:] and lldb successfully halted just before the exception occurred.
Now it seems to me that Apple is doing some dirty logic in -[_UIBarItemAppearance forwardInvocation:] to realize what selector should be sent to what instance, like:
setBackgroundImage:forState: should be sent to UINavigationButton
setBackButtonBackgroundImage:forState:barMetrics: to UIBarButtonItem
...
And their code looks like this:
if (selector == #selector(setBackButtonBackgroundImage:forState:barMetrics:)) {
// forward to UIBarButtonItem
} else if (selector == #selector(setBackButtonBackgroundVerticalPositionAdjustment:forBarMetrics:)) {
// forward to UIBarButtonItem
} else if (...) {
// more forwarding to UIBarButtonItem
} else {
// forward to UINavigationButton
}
Then, according to my deduction, the last else statement is causing setNiceBarButtonItemAttributes: selector being sent to UINavigationButton, not UIBarButtonItem. If it's true, we're doomed.
Sample code

Help
Am I just doing something wrong, or is it a bug? Or maybe Apple did it on purpose? Any help would be appreciated.
The problem is UIBarButtonItem is not a subclass of UIView, it is a "controller" class which creates private UIView subclasses. For bar button items, there is a private appearance proxy which is used, instead of the usual one (some information here).
May I suggest going a different route? Do you really need to subclass bar button items for your customization? Could you not create a subclass of UINavigationBar and use that as your trigger for changes with appearanceWhenContainedIn:?
OK, I ended up using a customView. Seems that it's the only way..

i've created an app which loads another viewcontroller from main view controller.example from viewcontroller 1 to viewcontroller2...in viewcontroller1 if button is pressed it needs to load viewcontroller2.and in viewcontroller2 i got icarousel view too..Here is my code
-(IBAction)showcoll:(id)sender{
CollectionsViewController *sec=[[CollectionsViewController alloc]initWithNibName:Nil bundle:Nil];
sec.modalTransitionStyle=UIModalTransitionStyleCrossDissolve;
NSLog(#"hi");
[self presentModalViewController:sec animated:YES];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
CGRect splashFrame =splash.frame;
splashFrame.origin.x = self.view.bounds.size.width;
[UIView animateWithDuration:3
delay:1.0
options: UIViewAnimationCurveEaseOut
animations:^{
splash.frame = splashFrame;
}
completion:^(BOOL finished){
NSLog(#"Done!");
}];
[self.view addSubview: splash];
}
and the issue which i got is

This Sigabart is not happening when you present the modalViewController, but instead it looks like you are setting a UIView to a dataSource in your CollectionsViewController I'm guessing you're doing something wrong in the viewDidLoad, because you never actually see the view yet.
Two questions:
You have not specified a nib name when you created CollectionsViewController. Did you mean to use nil for the nib name?
If you're not using a nib, I'm not sure where your splash view is being created, but I'm curious about your animation of the frame, and then animating the changing of that frame, but adding splash as a subview after you initiate the animation. Was it already on the view (and if so, why adding it again)? If it wasn't, (a) where are you creating it, and (b) why aren't you adding as a subview before the animation?

terminate called throwing an exceptionkill
Thank you very much for help
Here is the some code in viewdidload
UILongPressGestureRecognizer *lpgr = [[UILongPressGestureRecognizer alloc]
initWithTarget:self action:#selector(handleLongPress:)];
lpgr.minimumPressDuration = 0.2; //user needs to press for 2 seconds
[mapView addGestureRecognizer:lpgr];
[lpgr release];
That trace data is much better formatted now. Now I see it's happening on the loadFromNib, not even when the user performs a long press. And it makes sense especially if the nib was copied in from another project.
Please see if you can find a gesture recognizer in your nib. If it's there, check the connections inspector. It might have some invalid references, possibly to symbols in another project. (You'll probably see a little "!" near one or more of the connections).
If you find that, then problem solved. Delete it, and use the GR you've set up in code. (or re-configure the pointers in the nib and comment out the code in viewDidLoad:).

Unrecognized selector sent to instance (self.navigationController.toolbar)

I've been banging my head against the wall for the past 2 days with it - and I need help.
In my controller, I have this code:
- (void)viewDidLoad {
[super viewDidLoad];
self.navigationController.toolbar.barStyle = UIBarStyleBlack;
[self.navigationController setToolbarHidden:NO];
... // the rest of initialisation goes here
}
This controller presents details of one item selected from the list. Controller displaying a list of items does pushViewControllerAnimated on this controller to display details of the item selected by the user.
This works fine on the first execution, however when the user presses back button - and then selects another (or even the same) item from the list, line [self.navigationController setToolbarHidden:NO] causes SIGABRT with this stack trace:

I thought, maybe, I should setup self.toolbarItems first before making the toolbar visible - but then I get this same error when I do
self.toolbarItems = [NSArray ...]
I'm desperate now - any help is appreciated.
Edit: Now for some reason I'm getting EXC_BAD_ACCESS instead of SIGABRT - in the same place - and no stack trace is produced at all.
As the stack trace tells:
-[NSCFNumber view]: unrecognized selector sent to instance 0x69db0e0
You are accidentally overreleasing something that is leading to this message sent to some dangling pointer (reference to some junk).
Check if you are releasing your navigationController, ViewController or anything where your workflow begins.

app crashes after xib edit

I have a navigation controller app. I created a RootViewController class with Xib file. In that xib file I had table view and nothing more else. Toolbar and buttons on the toolbar I created in program way. Table view had datasourse and delegate File Owner.
I deleted this xib file, and created a new one with previous name. Created it like viewBased xib file and then I dropped down to it table view, toolbar, two buttons on toolbar. Add outlets on them. Saved it all. Clear all targets. Build all. And Run. Application crashes on start! Anyone know where may be the problem? Thanx!

Your view controller lost connection for view outlet, you need to restore it in IB (as you do with all outlets)
