I have added a tabbarcontroller on window and a button on view respective to first tab.
As I run the app and press the button, the app is crashing with this msg:

This happens when you try to call a method that doesn't exist. It looks like you've set up your button to send a message to the view controller (barButtonPressed:), but you may not have implemented the method if your view controller. Or you may have misspelled the method name or not included the argument in the method implementation.
Post your view controller code.
It looks like the button is trying to call barButtonPressed: on the view controller, but that method doesn't exist. Are you sure you don't get warnings during compilation regarding missing methods? My guess is you're not setting the view controller class correctly in a nib file.
Have you implemented barButtonPressed:? Are you sure you need the colon? Try barButtonPressed as the selector name instead.
This is an old question, but I think I know what happened. Notice how the error message says UIViewController instead of TodayDeal; he needed to change the Xib's file owner from a default UIViewController to TodayDeal

I am having a strange problem in xcode. i created a button in xib and connected to a function. I am printing the message inside the function. That's all, when i click the button i get the following error. I tried clean and deleted app from my simulator.

this is perhaps you are trying to call a method languageSelection with object that is infact string, but you have passed into another object which has languageSelection method.
this is because you think the object is what you want but the pointer passed the allocated memory to string and hence it will work as string. when you try to call method it crashes because it didn't find the method in string. check your object type just before u use it anywhere
I have one tabbar with several views, one with a tableview connected to Core Data. Now I've made one more tableview in a different project, and I want to merge it to my first project. This isn't new to me, I've done it before in another project where I had three tableviews with different core data tables, all working good. So I thought this would be a walk in the park.
In my AppDelage.m and .h I've added and copied all the code for the managedObjectContext to managedObjectContext2. And made a new navigation controller, "navigationController2".
ProtokollList *protokollList = (ProtokollList *)[navigationController2 topViewController];
// Set its managedObjectContext property to the managed object context
protokollList.managedObjectContext2 = self.managedObjectContext2;
// Get the root view controller; it's in the topViewController property of the navigation controller
KortKategori *kortKategori = (KortKategori *)[navigationController topViewController];
// Set its managedObjectContext property to the managed object context
kortKategori.managedObjectContext = self.managedObjectContext;
And then in my ProtokollList.m I've changed managedObjectContext to managedObjectContext2. And made necessary connections in MainWindow.nib.
But when I try to run the project I get this error message:
2011-07-24 18:22:58.188 Kortspel[1346:207] Unknown class ProtokollList in Interface Builder file.

I don't know it says that it doesn't recognize "ProtokollList" class, because it's defined in ProtokollList.h.
Does anyone have any idea? This is the last step before launching!
EDIT:
If I try to blank out:
/*
ProtokollList *protokollList = (ProtokollList *)[navigationController2 topViewController];
// Set its managedObjectContext property to the managed object context
protokollList.managedObjectContext2 = self.managedObjectContext2;
*/
I can open the project, but when I click on ProtokollList-tableview I get this new error message:

Best regards,

EDIT:
I understand that the critical point is the warning about IB (did not notice it at start)...
Could you check that ProtokollList.h and ProtokollList.m are effectively assigned to the target you are building? (I think so, otherwise you would have more linking problems, anyway, this is a basic check).
If this is ok, then I would simply try a clean and rebuild all.
If this does not fix the problem, then this might mean that the linker is not including ProtokollList.m in the final binary because of some optimization (the class is possibly never referenced in the rest of your code, just in Interface Builder). The fix for this is adding -all_load to the linker flags of your project.
If this does not help, I am very sad but I have no more suggestions...
You are calling:
protokollList.managedObjectContext2 = self.managedObjectContext2;
and no property named managedObjectContext2 is found in protokollList. This can be inferred by the line:
-[UIViewController setManagedObjectContext2:]: unrecognized selector sent to instance 0x4d13c40
So, you should possilby define managedObjectContext2 in protokollList (which should be a UIViewController).
EDIT;
interface ProtokollList : UITableViewController <NSFetchedResultsControllerDelegate> {
NSFetchedResultsController *fetchedResultsController2;
NSManagedObjectContext *managedObjectContext2;
}
#property (nonatomic, retain) NSManagedObjectContext *managedObjectContext2;
#end
I have encountered application termination while dismissing a modal view controller.

Above is the crash log. Please help.
Thanks in advance.
From you log it seems that you are calling window on an NSCFString. NSCFString does not have a window selector, and the compiler would complain if you try and do so, so it is likely that you are sending that message to a deallocated object (imagine that a new object has been allocated where another one was previously), or you are messing with casts.
In case you suspect that you are sending the message to a deallocated object, enable NSZombies.
Without seeing the code, it is not possible to help you further, though.
I downloaded the OHGridView hoping that it was the answer to all my problems.
https://github.com/AliSoftware/OHGridView
I did all that it said to do (add the class files, add the code, and change a few other things).
I went to build it and it crashed. I realized the lines of code why it was crashing:
((OHGridView *)self.view).rowHeight = 100;
((OHGridView *)self.view).columnsCount = 2;

I removed them and it loaded fine but I didn't see any content.
Please help,
thanks.
I did a clone of the repository just now and then did a build and run of his example project without making any changes to the code. It ran without any warnings or errors.
You'll need to check your code wherever you made changes.
update after your comment
Unrecognized Selector often means that you have a capitalization error or that your code isn't the kind of object that you think it is.
For example: I can get almost the same error that you get if I try to call the setRowHeight: directly against a OHGridView object instead of the view property of the object, like this
((OHGridView*)self).rowHeight = 100;
((OHGridView*)self).columnsCount = 2;
So, I would check your code to make sure that your object is an OHGridView and that you are setting the rowHeight property of the view of the OHGridView.
I'm pushing a simple view onto a NavigationController. The view loads fine, and when I use the built-in back button, it is properly popped.
However, when I try and pop the view with my own UIButton within the view, I get a crash.
This is the action run by my UIButton:
-(IBAction)iAgreePressed {
[[self navigationController] popViewControllerAnimated:YES];}
Am I missing something obvious here?
This is the error coming back in the console:

Thank you for your time!
Method signatures don't match. The button is sending
-[LegalAgreementController iAgreePressed:]
but you defined
-[LegalAgreementController iAgreePressed] //(note one arg versus no arg)
IBActions should be defined as:
- (IBAction) someMethod:(id)sender
You don't strictly have to include that arg, but you want to for consistency.
