I am getting a random bug in my app, which is causing it to crash. The problem I am facing is XCode doesn't tell me where the crash is happening only the below information. Can someone tell me how I can find out where I might be able to find the problem within the code? It must be crashing at the same point as when the app does crash it always shows the below.

Have you turned on exception breakpoints? Click the + at the bottom left of the Breakpoint Navigator, then select Add Exception Breakpont.
You can right click the breakpoint to edit it…
This will cause the code to stop at the point where the error occurs.
There is a solution that I usually use on my projects, setting up some special breakpoint.
To do that:
Open XCode
Goes to "View -> Navigators -> Show Breakpoint Navigators"
Now add some new breakpoints clicking the "+" button:
Add exception breakpoint
Add Symbolic breakpoint with symbol [NSException raise]
Add Symbolic breakpoint with symbol objc_exception_throw
Run again your project, application will stop on the line that is causing your problems.
error is evident enough. in any of your line, where you are setting some object for dictionary, you key is nill, which is not allowed
your problem is that you are using setObject: forKey Method to NSDictionary just make it NSMutableDictionary then try this method you can't assign value for NSDictionary like you are trying it's only for NSMutableDictionary.
i hope you will get my point what i am try to say.
Try this:
if([myDictionary objectForKey:#"string"]!= nil && [myDictionary objectForKey:#"string"]!= Nil) { }

When I follow this tutorial, it gives me an error on the [playercontroller release]; line, so I remove it, and then it gives me these errors when I try to run it.
I tried making another app to test the video, and it works seamlessly, but it will not work in my main app. Can anyone help?
And when I reimported the framework, and tried to play the video, it gives me this error:

I take it GVE1ViewController is a class you wrote yourself? Does it definitely implement a method called GrommeVideoExcerpt1? Is what you assigned to the variable actually an instance of GVE1ViewController (or a subclass?) Put in an NSLog to check that it really is an instance of GVE1ViewController.
To do the NSLog, you need a line of the form:
NSLog(#" My controller = %#", myVar);
where myVar is whatever variable you have containing a reference to the GVE1ViewController.
Ok so yesterday I had some trouble with this error, turned out I just needed to be patient and read through more of the book. This time I have got to the end of the project and I am getting this error at a different point.
I have isolated the line of code causing the issue but I'm not sure what the issue is!
htmlString=[htmlString stringByAppendingString: appDelegate.savedNumber];
Debug console is saying:

Anyone have any ideas? :)
It is because appDelegate.savedNumber is nil (does not set) . And why it is nil this is another question.
Looks like exactly what's written, you're passing nil argument to the method. Check if your savedNumber is a valid string object.
I'm having trouble to use RegexKitLite to match string like
NSString *encodedPoints=[apiResponse stringByMatching: #"\\\"([^\\\"]*)\\\"^[^:]*"
capture: 0];
and apiResponse is:
#"http://maps.google.com/maps?output=dragdir&saddr=20.001364,73.749283&daddr=19.991499,73.744095"
So, to do by this way i am getting following error:
__NSCFString stringByMatching:capture:]: unrecognized selector sent to instance 0x131fc0
* Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFString

Please help...
Ensure you have the correct library included into your project.
Go to your Project Navigator and selet the project.
Click on the Target and select the Build Phases tab, and open the Link Binary With Libraries.
Press the + Button, and search for libicucore.A.dylib. Add this library to your project.
Next, you will need to add the compile source, which is in Compile Sources just above Link Binary With Libraries. Once again, hit the + button and add RegexKitLite.m to the target. If you attempt to build the project at this state, you should get a lot of errors in the RegexKitLite.m file. To correct this, add the following compiler flag to the file by double clicking the RegexKitLite.m file in the Compile Sources area and then including -fno-objc-arc into the pop-up that appears. Hit done, and you will have hopefully added the library source to your project.
Just as a note, -fno-objc-arc removes the Automatic Reference Counting while compiling that source file. The errors the file gets without that compiler flag have to do with ARC, so it solves the problem.
This solved my issues when working with RegexKitLite, so hopefully it will for you.

Xcode - How to fix 'NSUnknownKeyException', reason: … this class is not key value coding-compliant for the key X" error?

Closed 7 years ago.
i´m very new to xcode... a made an app (simple calculator) work´s pretty good (on simulator and device).
When i set the main interface in the summary options from Target, i get the following error when starting the simulator:

to find the problem, i started a new view based project.
Run the empty new project on the simulator -->works,
But when I set the main interface, to ViewController, in the summary -->the Simulator crash with

is there a solution for the problem?
If you have a control in your nib (xib file) that is linked to a property (IBOutlet) or method (IBAction) in your view controller, and you have either deleted or renamed the property or method, the runtime can't find it because it has been renamed and therefore crashes.
In your case, you have set the Main Interface property of the project to your ViewController.nib. This is a problem because the only nibs that should be used as Main Interface should have UIWindows in them and the File Owner in that nib should be set to the AppDelegate. The UIWindow in the nib should be linked to the File Owner's (AppDelegate) window property. Because you set that with a nib without the traits the runtime was looking for, it gives you this error.
The solution is to leave the Main Interface blank as you do not have to set up UIWindows manually anymore.
Just had the same problem and fixed it by right Control-Clicking controls in the xib file to see referencing Outlets. Turned-out that some of the control were still referencing and older name and causing this error to happen.
if you get a message similar to:
Terminating app due to uncaught exception 'NSUnknownKeyException', reason:
'[ setValue:forUndefinedKey:]: this class is not key value coding-compliant for the key
click the add (+) at the left bottom corner of the BreakPoint navigation area, choose 'add Exception Breakpoint', since it is crashing because of 'NSUnknownKeyException', and opt for 'All'. Run the program. The program stops at the first exception.
try this, select File's Owner then click on the "Connection Inspector" (upper on the top of right pane), you will see all the outlets. Look for any sign like this (!) you will find it on the small circle which indicates a missing outlet, all you have to do is linking it properly or remove the outlet.
Try this,
Go to Target=>Build Phases=>Compile Sources
Then include 'calculatorScreen.m'
I was facing the same problem. In my case i had renamed the text label in .h file. So there was multiple reference for that label in my main.storyboard file. Once i removed old reference my code started working.

need help desperately ahead of a demo in a few hours... App was working on my test device fine last night. Added some data (as I always do) this morning and now I get this error during a save operation:
Serious application error. Exception was caught during Core Data change processing:
*** -[NSCFDictionary setObject:forKey:]: attempt to insert nil value
(key: _ContentChange_OldIndexPathKey) with userInfo (null)
*** Terminating app due to uncaught exception 'NSInvalidArgumentException',
reason: '*** -[NSCFDictionary setObject:forKey:]: attempt to insert nil value
(key: _ContentChange_OldIndexPathKey)'
The funny thing is that if I download my sqlite file to my Mac and feed it into the simulator, everything works just fine. The crash only occurs on the test device.
Any ideas?
I too was encountering this error. Nullifying the NSFetchedResultsController delegate does stop it from crashing, but is not a fix. The problem seems to be specifying a sort key in the NSFetchRequest which is null for some objects. Some sort call made in NSFetchedResultsController expects none null values.
This is an old post but I will give my comment anyway :)
I have experienced similar problem and deleting the cache for the NSFethedReultController solved the problem.
[NSFetchedResultsController deleteCacheWithName:<cacheName>];
