My app is crushing when i'm calling a few methods
I can see the error message and I understand what it say but I don't know how to detect the array with the problem by the message.
I have lots of arrays in the project.
how can I know from where the problem come from?
this is the message:

libc++abi.dylib: terminating with uncaught exception of type NSException
To handle All exceptions, From Xcode click on Show the Breakpoint Navigator
Click + button at bottom side and from pop up click on Add Exception Breakpoint.
This will add exception break points for application, try to run again and execution will stop if any runtime exception raised.
If this will not help, enable zombie environment for project, check out from this thread -
How to set exception breakpoint from Xcode
Enable Zombie Object in Xcode for better error tracing.
To enable
Press Command+Option+R
Under Diagnostic tab-> Memory Management
Check "Enable Zombie Object"
Hope this Helps

This is the exception and in my ignorance of using the tools in the IDE I have a very basic question. How do I go to the line of code that causes the issue? I have located where the issue is, but rather than NSLogging a message in the didload and didAppear events, then stepping through the code until is breaks seems like a long way to figure this out. I am assuming that the [5970:1623718] is a clue, but to what?

You can add an "Exception Breakpoint".
Like in the picture, select "Show the Breakpoint navigator" (the blue icon on the top of the navigator), then click on the plus icon on the bottom and click on "Add Exception Breakpoint".
I am trying to run my application and suddenly i get this error:

It's on the start of the application,
i get this error without changing any code in my project, any idea what can cause this?
To resolve the NSException crashes, you have to remove all the warnings of .xib/.storyboard files. Cross check the IBOutlets warnings and you can see a cross (X) icon related to the yellow warnings to remove it.
I've implemented an In-App-Purchase into my app.
If I run my app and press the "purchase" button, i get the following error:
2014-10-22 17:48:20.733 MyApp[170:3435] *** Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array'
Does someone got the same error and know what's to do?
It is the typical exception that emerges when handling an empty array.
Add an exception breakpoint to your project in Xcode, as shown in the picture.
It will stop the execution of the app in the line that the exception does happen
The following is the exception I get from iOS. It looks ridiculously unreadable (my brain is screaming wtf ten thousand miles per second). So this can’t be right. When I am developing for android, and I get an exception, the stack trace is completely readable, no magic such as 0x187d27bc8. So am I looking at the wrong window? Where in Xcode to I go to find a readable version of my stack trace? In eclipse there is a line number I can click on to get to the exact line that caused the error.

In your menu bar go to: Debug -> BreakPoints -> Create Exception BreakPoints. And that should do it. So the next time you run the code, it will stop at the line that caused the exception. And then to the left, you should see the stack trace.
I've got the Cocoa Touch project with ARC and this error sometimes occurs. Can You explain me the kind of this error and the way to solve this?

You have a zombie problem. If you can reproduce this on the simulator, run it under the Zombies instrument. If you can only reproduce it on the device, edit your scheme, go to the Diagnostics tab, and turn on the zombies checkbox there. (Instruments doesn't offer zombie detection on the device, unfortunately.)
The crash you're seeing has nothing to do with ARC and everything to do with the object (which appears to be a NSCFString object) that's receiving a bogus "deviceOrientationDidChange:" message.
My recommendation would be to set a symbolic breakpoint on "deviceOrientationDidChange" and catch the message being sent and then you'll know what line of code is broken.
