I have an XIB that I present as a modal view. I have a button that calls the following -
(IBAction)dismissVC:(id)sender {
[self.parentViewController dismissModalViewControllerAnimated: YES];
}
When I press it the app crashes with this notice -
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ViewController dismissVC:]: unrecognized selector sent to instance 0x8379350'
The thing I noticed is that I have a ViewController.xib file and I have this MapView.xib that is a modal VC I want to dismiss. It's presented from a ViewController.xib
What could be the possible issue? I've hooked up all the actions and the File Onwer thing as well.
Thanks in advance!
Try this:
unrecognized selector sent to instance
that might be your solution.

I can´t find nothing about:
UIPopoverController _presentPopoverBySlidingIn:fromEdge:ofView:animated:stateOnly:notifyDelegate:
I got following error message:
*** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UIPopoverController _presentPopoverBySlidingIn:fromEdge:ofView:animated:stateOnly:notifyDelegate:]: Popovers cannot be presented from a view which does not have a window.'
I start my iPad-App in Portrait-Mode. And because I need some steps to be done from the master-VC, I present the Popover-Controller programmatically via
[ _masterPopoverController presentPopoverFromBarButtonItem:self.navigationItem.leftBarButtonItem permittedArrowDirections:UIPopoverArrowDirectionAny animated:NO];
When I want to dismiss the Popover manually (via touch or swipe outside the popover), the above error occurs.
The problem exists since iOS 5.1.
This bug is befuddling to me, but here goes:
I was trying to set up an IBAction to run on touch up inside on a UIButton. For some reason, it wasn't working, and wasn't really giving me any gdb errors. Every now and then it would mention an unrecognized selector. I checked to make sure my File's owner was the correct class, and everything was in check and it was, so I ran it again and still nothing.
I figured it might be a problem with Interface Builder, so I used addTarget: on the button, setting the target as self, and the selector the selector of the method I wanted to call, and still got an unrecognized selector error. To test that the selector did exist, I ran a [self performSelector:] on the selector of the method I wanted, and it worked. So basically right now I have this:
- (void)viewDidLoad {
[super viewDidLoad];
[self performSelector:#selector(hi)];
[_backButton addTarget:self action:#selector(hi) forControlEvents:UIControlEventTouchUpInside];
}
- (void)hi {
NSLog(#"HI");
}
The perform selector works perfectly, and logs "HI". Here's the kicker, when I touchup on _backButton, it gives me an unrecognized selector error, even though I just called it and it worked:

I've taken screen shots of the nib and the implementation file, viewable here: http://imgur.com/a/q2a6N
Does anyone know what's going on?
The problem is probably happening because your instance of CaptionEditorViewController is being deallocated for some reason, as pointed by random classes throwing "unrecognized selector" exceptions
I want to go Root view Controller from another view controller but i got the terminating error. following is the error message in console,
Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[NSCFArray removeObjectsInRange:]: index (4) beyond bounds (1)'
This is my code for that
NSArray *arr=self.navigationController.viewControllers;
[self.navigationController popToViewController:[arr objectAtIndex:2] animated:YES];
So any one can give me the suggestion on it so can remove the crash
The NavigationController has a method called to pop to its root view controller. Maybe you should use this one instead.
- (NSArray *)popToRootViewControllerAnimated:(BOOL)animated
I created a tableView which worked fine in a single view app but as soon as I changed the view controller for a Tab Bar Controller and tapped the tab for the view with the table view in I suddenly get this! What has gone wrong?

You have an UIViewController somewhere, that should be an UITableViewController. Check your view hierarchy in Interface Builder.
I have a Tab Bar application with four new headers, implementation and interface files, and added those as the sources in IB. They were in this format: FirstView.h/m/xib, SecondView.h/m/xib.
I then had files for First-, Second-, Third- and FourthView.
There was also a file there called FirstViewController. I did not touch this, I just deleted it because I wasn't going to need it.
I then laid out my interface for the first view (FirstView.h/m/xib) in IB. It had an image on the top, label under and a UITableView under that.
I sat up the correct connections (delegations and datasource for the tableview) in my FirstView.h/m file, and pressed Build. It seemed to build without errors, so I pressed Build and Go.
The Simulator popped up, installed the app and crashed. (Error message:Terminating app due to uncaught exception).
Complete error message:

I asked about this in another question, got an answer, and that fixed it:
It was obviously looking for code in the FirstViewController.h/m-file, although I did not do anything to make it look for code there.
I fixed this by adding two interfaces and implementations in my FirstView.h/m file. (FirstView and FirstViewController)
When I ran the app then, the table view and tab bar came up on the screen, but my image and label did NOT.
I don't have any idea of why it was looking for the code in FirstViewController instead of FirstView... I have the correct connections in IB, too..
A tableview is trying to query its data source for the number of rows it should display. If you've connected the tableview's datasource outlet to an instance of your FirstViewController class, then you need to implement -tableView:numberOfRowsInSection: in that class.
