EXC_BAD_ACCESS crash UINavigationController as ContentViewController

[acajic]

UINavigationController *mainNC = [[UINavigationController alloc] init]; mainNC.viewControllers = @[someController];

I instantiate REFrostedViewController with mainNC as contentViewController property:

REFrostedViewController *reFrostedVC = [[REFrostedViewController alloc] init]; reFrostedVC.contentViewController = mainNC; reFrostedVC.menuViewController = ...;

Everything works fine.

Later I want to set mainNC's viewControllers to some other view controllers like this: mainNC.viewControllers = @[someOtherVC];

The app crashes with EXC_BAD_ACCESS error.

If I call: [mainNC pushViewController:someOtherVC animated:NO];

It works fine, but this is not what I want.

OK, the problem has been encountered before, it is a iOS 7.1 thing:

I managed to fix it by setting some scrollView's delegate to nil. Share your thoughts on this if you have something useful.

The moment I inherit a protocol in Login in which I have import REfrostedViewController.The app crashes at

• (id)init { self = [super init]; if (self) { [self commonInit]; } return self; } Thread 1: EXC_BAD_ACCESS (code=2, address=0x16ea0ffb0) What is the problem.I cant use protocol and delegates at this page at all.

In my App logs :libsystem_malloc.dylib`tiny_malloc_from_free_list:is showing
