In my app I’ve a navigation Controller that is connected to another viewController (root controller). In my project I’ve imported ECSlidingViewController.h and .m. In the viewController that will be used as a right-side menu (listViewController.h), I’ve imported ECSlidingViewController.h and in viewDidLoad I did this:<\/p>\n
[super viewDidLoad];\n self.peekLeftAmount = 40.0f;\n [self.slidingViewController setAnchorLeftPeekAmount:self.peekLeftAmount];\n self.slidingViewController.underRightWidthLayout = ECVariableRevealWidth;\n<\/code><\/pre>\nIn the navigationController class instead, I did this (after imported ECSlidingViewController.h and listViewController.h):<\/p>\n
- (void)viewWillAppear:(BOOL)animated\n{\n [super viewWillAppear:animated];\n\n if (![self.slidingViewController.underRightViewController isKindOfClass:[ListViewController class]]) {\n self.slidingViewController.underRightViewController = [self.storyboard instantiateViewControllerWithIdentifier:@\"ListStore\"];\n }\n\n [self.view addGestureRecognizer:self.slidingViewController.panGesture];\n}\n<\/code><\/pre>\nBut when I run the app, when I get to the line of code [self.view addGestureRecognizer:self.slidingViewController.panGesture];<\/code> the app crashes, and gives me the following error:<\/p>\n2013-09-28 01:59:55.629 Myapp[2627:a0b] *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[__NSArrayM insertObject:atIndex:]: object cannot be nil'\n*** First throw call stack:\n(\n 0 CoreFoundation 0x024595e4 __exceptionPreprocess + 180\n 1 libobjc.A.dylib 0x01a6f8b6 objc_exception_throw + 44\n 2 CoreFoundation 0x0240bc3c -[__NSArrayM insertObject:atIndex:] + 844\n 3 CoreFoundation 0x0240b8e0 -[__NSArrayM addObject:] + 64\n 4 UIKit 0x0063f497 -[UIView(UIViewGestures) addGestureRecognizer:] + 208\n 5 Myapp 0x0001a934 -[MainNavigationController viewWillAppear:] + 564\n 6 UIKit 0x006ec28a -[UIViewController _setViewAppearState:isAnimating:] + 419\n 7 UIKit 0x006ec798 -[UIViewController __viewWillAppear:] + 114\n 8 UIKit 0x006fd310 -[UIViewController(UIContainerViewControllerProtectedMethods) beginAppearanceTransition:animated:] + 199\n 9 UIKit 0x0097d627 -[UIWindowController transition:fromViewController:toViewController:target:didEndSelector:animation:] + 6236\n 10 UIKit 0x006f478c -[UIViewController presentViewController:withTransition:completion:] + 6433\n 11 UIKit 0x006f4caf -[UIViewController presentViewController:animated:completion:] + 130\n 12 Myapp 0x00017447 -[SplashScreenViewController viewDidAppear:] + 839\n 13 UIKit 0x006ec2d8 -[UIViewController _setViewAppearState:isAnimating:] + 497\n 14 UIKit 0x006ec867 -[UIViewController __viewDidAppear:] + 146\n 15 UIKit 0x006ee22f __64-[UIViewController viewDidMoveToWindow:shouldAppearOrDisappear:]_block_invoke + 44\n 16 UIKit 0x006ecbfa -[UIViewController _executeAfterAppearanceBlock] + 63\n 17 UIKit 0x005f1d59 ___afterCACommitHandler_block_invoke_2 + 33\n 18 UIKit 0x005f1cde _applyBlockToCFArrayCopiedToStack + 403\n 19 UIKit 0x005f1b2e _afterCACommitHandler + 568\n 20 CoreFoundation 0x0242153e __CFRUNLOOP_IS_CALLING_OUT_TO_AN_OBSERVER_CALLBACK_FUNCTION__ + 30\n 21 CoreFoundation 0x0242148f __CFRunLoopDoObservers + 399\n 22 CoreFoundation 0x023ff3b4 __CFRunLoopRun + 1076\n 23 CoreFoundation 0x023feb33 CFRunLoopRunSpecific + 467\n 24 CoreFoundation 0x023fe94b CFRunLoopRunInMode + 123\n 25 GraphicsServices 0x032da9d7 GSEventRunModal + 192\n 26 GraphicsServices 0x032da7fe GSEventRun + 104\n 27 UIKit 0x005d594b UIApplicationMain + 1225\n 28 Myapp 0x00002b2b main + 235\n 29 libdyld.dylib 0x01f54725 start + 0\n 30 ??? 0x00000001 0x0 + 1\n)\nlibc++abi.dylib: terminating with uncaught exception of type NSException\n<\/code><\/pre>\nPlease, help me!<\/p>\n","protected":false},"excerpt":{"rendered":"
