I used ARSCNView to draw objects in virtual reality
Now I want:
clone ARsession new from ARsession old
Pause() ARsession in an old version
Only work on a new version
Note: If you don't clone but just try the assign, then when to pause() ARsession in the old session, the new session will also pause()
How I did it:
let session = arscnView.session.copy() as! ARSessionv
==> Result: Error --- Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[ARSession copyWithZone:]: unrecognized selector sent to instance 0x101b93c30'
How can I do this?
Thanks for reading.

So I'm loading some images from files which I saved in the app's document directory and upon completion, I update a dictionary which holds all the images for my tableview. So far so good, everything's working just fine.
But now I've stumbled upon a really peculiar crash. Sometimes when updating the dictionary the app crashes, giving me the error message: "Heap corruption detected, free list is damaged at ...".
I've added a symbolic breakpoint at malloc_error_break and turned on the Address Sanitizer the Undefined Behaviour Sanitizer and Zombie Objects as advised in this post: iOS error : Heap corruption detected, free list is damaged and Incorrect guard value: 0
Now I'm getting the following error message, which doesn't really help me either:

I have no clue as to what could've caused that crash, hopefully someone can help me out here!
I'm testing the Sphero-AR-SDK found on GitHub (https://github.com/orbotix/Sphero-AR-SDK)
When testing, I seem to have random crashes on connect.
The issue I'm trying to debug is an index out of range error.
*"*** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array'
*** First throw call stack:

libc++abi.dylib: terminate called throwing an exception"*
This happens a fair amount when booting the application but not all the time (sometimes it will get through and play the game).
I was wondering if anyone else was having issues with these random crashes or have I not set it up correctly?
I've had a look at the "Other Linker Flags" in XCode too and it has -all_load.
Also, I've safely checked the only place where I could find an array object access in the .mm files (RKUNBridge.mm) has this line:
[RKDeviceSensorsData *data = [sensors_data.dataFrames objectAtIndex:0];
And I safely checked this array exists and is greater than one to double check it's not this line.
Any ideas or suggestions would be much appreciated.
Thanks for reading.
I am trying to implement the getting started helloWorld, on XCode 4.6, but I am getting this sigabart. The code is exactly like the apple website. No errors are produced but in runtime I have this:

I did delete the connections and connect the label, textfield and button again to view controller.m but get the same result. I connectted the textfiled to the delegate but received the same result.
Can someone help elucidate what is going on?
Check for the linking of objects or methods in your storyboard connections inspector.
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.
I am trying to set my imageview:
detailedEventViewController.thumbnail.image = [UIImage imageNamed:#"amnesia.png"];
but get the error:
2011-01-08 09:53:24.153 HD Pocket Vacations[24697:207] -[DetailedEventViewController thumbnail]: unrecognized selector sent to instance 0x624d820

My outlets are wired up correctly.
There must be a problem with your "thumbnail" property.
As such, you'll need to check:
Whether it's been correctly defined and synthesized within your interface and implementation file(s).
Whether it's an UIImageView.
The spelling on all of the above.
