I have problem with custom overlay. The problem is I cant identify error code, its occurs randomly
Maybe someone will be able to help me basic on this stack. What is pointCount?

What the error means is that there is an MKPolygonView in your overlay. The polygon property of the MKPolygonView is set to an instance of MyRegionOverlay. Unfortunately MyRegionOverlay is not a subclass of MKPolygon as it is supposed to be. So when the pointCount message is sent to the MyRegionOverlay you get a run time error "unrecognized selector" since MyRegionOverlay apparently does not respond to pointCount.

This occurs (under certain unknown conditions) when I call layer.presentation() on the backing layer of an NSView. Does anyone know why getting the presentation layer could result in the unrecognized selector error?
I have encountered application termination while dismissing a modal view controller.

Above is the crash log. Please help.
Thanks in advance.
From you log it seems that you are calling window on an NSCFString. NSCFString does not have a window selector, and the compiler would complain if you try and do so, so it is likely that you are sending that message to a deallocated object (imagine that a new object has been allocated where another one was previously), or you are messing with casts.
In case you suspect that you are sending the message to a deallocated object, enable NSZombies.
Without seeing the code, it is not possible to help you further, though.
Just trying to implement mobFox into my app, but having trouble to make it run. I suspect that it is because of my general approach not to use IB at all, because the sample code works just fine.
After run it is pointing to the line
int retVal = UIApplicationMain(argc, argv, nil, #"UntitledAppDelegate");
which is in my main.m,
with this as result

Did you set the linker-flags as described in the SDK documentation?

'-[NSXMLParser length]: unrecognized selector sent to instance 0x6e6d340
this shows you are calling a function which is not a member function of NSXMLParser class.
actually in your code you are calling any method which can not be invoke on the obeject of NSXMLParser class.
chechk by debugging pointer.
I just suffered from this same issue. For me the problem was caused by this line of code:
operation.responseSerializer = [AFXMLParserResponseSerializer serializer];
This serialised the responseObject I was passing into the parser to XML but the parser expects an NSData object. Simply getting rid of that line solved the problem.
I also faced the similar problem.
Fixed by changing my line
self.xmlParser = [[NSXMLParser alloc] initWithData:data];
to
self.xmlParser = (NSXMLParser *)responseObject;
I found my solution from this blog
Raywanderlick Blog
Explanation for Error
This configuration of [AFXMLParserResponseSerializer serializer] already return an initialized object and I was initializing it again using already initialized parser by considering it data object.
Commenting following line didn't work for me as suggested by #Hodson answer above and it doesn't make sense as this is default configuration of AFTNetworking library.
operation.responseSerializer = [AFXMLParserResponseSerializer serializer];

terminate called after throwing an instance of 'NSException'
How would I fix this? Thanks.
Set a breakpoint on objc_exception_throw, then build the app for debug, run the app with breakpoints on and cause the crash again, then go up the stack to the relevant code.
Something inside SHKOAuthView webView:shouldStartLoadWithRequest:navigationType: is passing a nil argument to NSString rangeOfString. When you know what is passing the nil, it may be obvious what the problem is - failing that update your question with the relevant code and any extra information you've determined.
