Getting this error intermittently in production. Fails on objMsgSend for isKindOfClass. Having difficulty reproducing in development, would like to be able to do so. Have tried showing and dismissing the UIAlertController with other view controllers on the screen, moving to and from background etc. EDIT: Have now been able to reproduce this. Occurs when the UIAlertController appears with (shows underneath) an existing popover in the app. EDIT2: Appears to be an issue on iOS8, but less frequent although still occurring in iOS9

My app is crashing for the apple review team but I can't replicate the issue. They sent me the crash log.

How can I debug when I can't replicate the issue? Has anyone experienced this issue. My app was working fine in previous versions but this time it is crashing in 5.1.1. Any help would be greatly appreciated.
What does [MenuViewController showStageList:] contain on line 62!?
Obviously you are calling a method, that's non existent: [NSObject doesNotRecognizeSelector:].
While analyzing our crash logs I discovered that a fairly common crash is one that does not even occur in one of my own classes. These are external crash logs and I can't therefore not reproduce the problem.
Since I can't debug the Framework I am wondering, what a practicable approach could be to tackle this issue.
The only clue I have is that SIGSEGV might be a segmentation fault or an invalid pointer. But like I said since my Classes do not seem to be directly involved this does not help me much.

This crash is likely a result of an error on your part. If you look at few of lines at the top of the stack trace it should give you a hint as to what is wrong.

It looks like somewhere you have an object (possibly a view controller) that is registered for events but is deallocated too soon. The best thing to do is try to reproduce this while attached to the debugger. Start by checking code that handles UIControl callbacks such as UIButtons.
This is a new one. I'm testing that my various viewcontrollers are getting loaded by my tab bar, so I put this on one of them:
- (void)viewDidLoad
{
[super viewDidLoad];
UILabel*yo=[[UILabel alloc] init];
self.testlabel=yo;
self.testlabel.text=[NSString stringWithFormat:#"sup"];
[yo release];
This is what I get when I click the tab button for that controller:

What in the world?! I must be doing something exceptionally basic and wrong here. Can anyone spot it?
I've got this in the .h and .m:
#interface SingleVC : UIViewController
#property (nonatomic, retain) IBOutlet UILabel*testlabel;
#end
and
#implementation SingleVC
#synthesize testlabel;
I get the following stack errors (which I do not know how to read):

So after some Googling on other sites, it turns out that quite a few people have had this exact same and basic problem. I found the solution here:
https://discussions.apple.com/thread/1598422?threadID=1598422
I was checking my classes within the individual nibs of each controller, but you must also set the classes in the tab controller as well, for each item (I had already set the nib name for each tab bar item, but not the class).
so, problem resolved and was, as expected, quite basic.
It's a stumper why the error created was for key value coding, though.
perhaps a connection in IB from some object that formerly had an IBOutlet called testlabel?
stop the debugger in ObjC Exceptions and post your stack trace if it's not obvious
Okay, I have a program that I'm trying to test on my iPad. I have it all set up so that the app is able to get on the iPad just fine, but running it on the iPad is a different story.
Now, the thing is, my program was working fine on the debug configuration, but now it won't work on that, either. It's strange, because before I was able to get to a certain part of the program before it crashed, but now it's crashing before that.
The debugger is hardly helping. When I use the debugger window, it will step into one line of code, and then suddenly jump back to another line of code.
I really don't understand what's going on. The crash is now occuring in a root view controller that I have set up, called 'FunctionMachineViewController. Here's the code for when it crashes:
-(IBAction)startOnePlayer:(id)sender
{
GameViewController* GameView = [[GameViewController alloc] initWithNibName:nil bundle:nil];
[GameView isOnePlayer:YES withLevel:startLevelNumber];
[self presentModalViewController:GameView animated:YES];
}
GameViewController is supposed to initialize just fine, but the debugger shows it as uninitialized. I even tried setting it up in the header file instead, but the problem still happens. Has anyone else come across these problems? Any help would be greatly appreciated!
EDIT: Here's what the console says when it crashes:

terminate called after throwing an instance of 'NSException'
Turns out that, when I went and changed the name of several UILabels in the header of GameViewController, I forgot to fix the names in the interface builder, too. Don't know if that was what was causing the debugger to act weird, but everything is working now!
I have created a TabBarView. On one of the tabs, I have a View with several Labels on it. It works fine.
When I connect the Labels in Interface Builder to the File's Owner (the corresponding IBOutlets) then the App crashes with the following error when I open that tab:

terminate called after throwing an instance of 'NSException'
I have read that it can be related to the xib not matching (correctly connected) to its view controller. I have no idea how to check or fix that?
This is how my header file looks:
//Stats.h
#import <UIKit/UIKit.h>
#interface Stats : UIViewController
{
IBOutlet UILabel *speedLabel;
IBOutlet UILabel *headingLabel;
}
#end
If anybody has any tips or links to other similar posts, I would appreciate it!
Thank you in advance!
