In this class Paint_BrushAppDelegate, you might be setting a key where the key might not be a proper NSString. Please check the syntax or object you are passing as key. Please check if it is not nil.

I have error like this.
This class is not key value coding-compliant for the key ptbLabel.
I know this error happens when there is something wrong with a linkage between storyboard and source code.
So, I deleted the linkage from storyboard.
then this error disappear.
However I reconnect again from Storyboard manually.
#IBOutlet weak var ptbLabel: UIImageView!
It shows the same error.
Why does this happen??
I guess it might be something related with project name change.
I have changed project name just a few steps before, by clicking the projectname at the top of left pain.
These are the error log below

I opened the storyboard as source code.
then found customModule is not changed when I changed the projectname.
<viewController id="2" customClass="viewController" customModule="OldProjectName" sceneMemberID="viewController">
I changed here OldProjectName -> NewProjectName
it works.
thanks very much.

So I'm not sure what is going on. I haven't really changed much. Nothing having to do with this class anyways. It was working fine just a bit before and now I'm getting this crash.
-(IBAction)mphButton:(id)sender{
if(self.mphVC == nil){
MphViewController *mph = [[MphViewController alloc] initWithNibName:#"MphView" bundle:[NSBundle mainBundle]];
self.mphVC = mph;
[mph release];
}
[self.navigationController pushViewController:self.mphVC animated:YES];
}
The thread is stopping saying "Thread 1: Program received signal "SIGABRT" on the [self.navigationController pushViewController:self.mphVC animated:YES];

I can read these pretty well on Logcat on android. Just not use to reading this one. I saw another post saying that their class might not have been connected to their view. Mine is. It was working just fine prior to me putting in some stuff (which I recommented out and it still isnt working) on the MPHViewController.m
Any and all help is appreciated... Thanks :)
You most likely have something in your "MphView" XIB file called "count" that you no longer have in MphViewController. Maybe a delegate set for an object that's no longer there, or an action, or something like that. Check all your connections in Interface Builder and remove any broken ones.
I added UITabBarController in my app but removed after some time. App was working fine before adding UITabBarController but when I removed it from app, I started facing below exception.

Any solution to get rid of this exception?
You have something connected to the tabBarController outlet of your app delegate in Interface Builder. However the outlet no longer exists, so you're getting this error. You should just find and remove that connection.
I seem to be having an issue with loading a game on a tab in a tab bar application. When I run the app and click on the tab that the game is supposed to go on, it crashes giving me this in console:

It seems as if you have a problem in the XIB you are trying to load. Make sure there are no invalid connections, i.e. connections to non-existent IBOutlets or IBActions. Also make sure you haven't defined any objects to be non-existent classes.

The error message: Terminating app due to uncaught exception 'NSUnknownKeyException', reason: '[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key customCell.'
... means that your xib is referencing an IBOutlet named "customCell" but your view controller doesn't have that IBOutlet anymore. You either need to remove the customCell reference from your xib or add an IBOutlet property to your view controller named "customCell".
