My application support is iPad only.
I have UISplitViewController in it.
Left Menu
UIViewController
UITableView
UITableViewCell
UILabel (Added UITapGestureRecognizer)
UIImageView
Center View
UIViewController
UIView
I'm Showing the popover when user taps on UserName label (Left menu -> Tableview -> Cell -> Label)
So my code in cellForRowAtIndexPath method is below.
__weak LeftMenuUserTCell *weakCell = cell;
cell.didTapProfileOption = ^{
NSLog(#"Option Tapped");
[self showMyProfilePopupFrom:weakCell.lblUserName inView:weakCell.lblUserName.superview];
};
and i'm presenting popover like this
-(void)showMyProfilePopupFrom:(UIView *)sourceView inView:(UIView *)parentView
{
ListViewController *listView=[[UIStoryboard storyboardWithName:#"Main" bundle:nil] instantiateViewControllerWithIdentifier:#"ListViewController"];
listView.listDelegate=self;
NSArray *optionList=#[#"My Profile",#"Change Password",#"Sign Out"];
listView.dataArray=[optionList mutableCopy];
listView.selectedItemIndex = -1;
listView.listType = 1;
listView.modalPresentationStyle = UIModalPresentationPopover;
UIPopoverPresentationController *popover = listView.popoverPresentationController;
listView.preferredContentSize = CGSizeMake(200, 150);
//popover.delegate = self;
popover.sourceView = sourceView;
popover.sourceRect = sourceView.bounds;
popover.permittedArrowDirections = UIPopoverArrowDirectionUp;
[self presentViewController:listView animated:YES completion:nil];
}
Till now everything is working fine.
Now I have to keep hidden left menu by default so i wrote following code in AppDelegate where i'm setting up UISplitViewController.
self.rootSplitViewController.preferredDisplayMode = UISplitViewControllerDisplayModePrimaryHidden;
Now Problem is my app is crashing when i tap the mentioned label. I have checked that my application is even not crashing when i comment out the above line (UISplitViewControllerDisplayModePrimaryHidden).
Following is the crash log :
MyApp[785:371642] invalid mode 'kCFRunLoopCommonModes' provided to

My code runs perfectly fine on iOS 10.3.3, whereas when I run the same code on iOS 11.2.1, it causes a crash at launch time with the following error:
Assertion failure in -[_UINavigationBarVisualProviderModernIOS _contentViewFittingHeight], /BuildRoot/Library/Caches/com.apple.xbs/Sources/UIKit/UIKit-3698.33.7/_UINavigationBarVisualProviderModernIOS.m:569
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Sigh. Contentview size is zero.'
I cleaned the code, cleared the derived data, but those did not solve the issue.
There was an issue in the library I was using for Slide menu "iOS-Slide-Menu". So, I simply changed this two very methods in the library which then worked fine.
- (void)setup
{
[[NSUserDefaults standardUserDefaults] setObject:nil forKey:#"ssidName"];
[[NSUserDefaults standardUserDefaults] synchronize];
if (singletonInstance)
NSLog(#"Singleton instance already exists. You can only instantiate one instance of SlideNavigationController. This could cause major issues");
singletonInstance = self;
self.menuRevealAnimationDuration = MENU_SLIDE_ANIMATION_DURATION;
self.menuRevealAnimationOption = MENU_SLIDE_ANIMATION_OPTION;
}
- (void)viewWillLayoutSubviews
{
[super viewWillLayoutSubviews];
// Update shadow size of enabled
if (self.enableShadow)
self.view.layer.shadowPath = [UIBezierPath bezierPathWithRect:self.view.bounds].CGPath;
self.landscapeSlideOffset = self.view.frame.size.width/6;
self.portraitSlideOffset = self.view.frame.size.width/6;
self.panGestureSideOffset = 0;
self.avoidSwitchingToSameClassViewController = YES;
self.enableShadow = YES;
self.enableSwipeGesture = NO;
self.delegate = self;
// When menu open we disable user interaction
// When rotates we want to make sure that userInteraction is enabled again
[self enableTapGestureToCloseMenu:NO];
if (self.menuNeedsLayout)
{
[self updateMenuFrameAndTransformAccordingToOrientation];
// Handle different horizontal/vertical slideOffset during rotation
// On iOS below 8 we just close the menu, iOS8 handles rotation better so we support keepiong the menu open
if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(#"8.0") && [self isMenuOpen])
{
Menu menu = (self.horizontalLocation > 0) ? MenuLeft : MenuRight;
[self openMenu:menu withDuration:0 andCompletion:nil];
}
self.menuNeedsLayout = NO;
}
}
Fixed out, that two lines must be in viewWillLayoutSubviews instead of setup method. And like #Ishika said, this is the problem of iOS-Slide-Menu.
self.enableShadow = YES;
self.enableSwipeGesture = YES;
This error occured to me with Xcode 10.2.1 and SideMenu 6.0.4. I ended up configuring the navigation controller programmatically, which solved the issue.
let sideMenuVc = UISideMenuNavigationController(rootViewController: <view controller>)
When I give a good swipe to my tableView and press the "Back" button before the tableView ended it's scrolling, my app crashes. I've tried the following:
- (void) closeViewController
{
[self killScroll];
[self.navigationController popToRootViewControllerAnimated:YES];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)killScroll
{
CGPoint offset = sellersTableView.contentOffset;
[sellersTableView setContentOffset:offset animated:NO];
}
That didn't work, same crash. I don't see why, the error I'm getting is the following:
*** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:'
So that means that the tableView is still requesting a cell when everything is already being deallocated. Makes no sense.
Then I tried this:
- (void) closeViewController
{
[self.navigationController popToRootViewControllerAnimated:YES];
[self dismissViewControllerAnimated:YES completion:nil];
}
- (void)dealloc
{
sellersTableView.dataSource = nil;
sellersTableView.delegate = nil;
sellersTableView = nil;
}
Gives me the same error. Any ideas?
Update:
My delegate methods
creation
if (textField == addSellerTextField) {
sellersTableView = [[UITableView alloc] initWithFrame:CGRectMake(addSellerTextField.frame.origin.x + addSellerTextField.frame.size.width + 10, addSellerTextField.frame.origin.y - [self heightForTableView] + 35, 200, [self heightForTableView])];
sellersTableView.delegate = self;
sellersTableView.dataSource = self;
sellersTableView.backgroundColor = [[UIColor grayColor] colorWithAlphaComponent:0.05];
sellersTableView.separatorColor = [[UIColor grayColor] colorWithAlphaComponent:0.15];
sellersTableView.rowHeight = 44;
sellersTableView.layer.opacity = 0;
[self.companyView addSubview:sellersTableView];
[UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseIn animations:^{sellersTableView.layer.opacity = 1;} completion:nil];
}
cellForRowAtIndexPath
if (tableView == sellersTableView) {
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.backgroundColor = [UIColor clearColor];
if ([sellersArray count] > 0) {
cell.textLabel.text = [sellersArray objectAtIndex:indexPath.row];
} else {
UILabel *noSellersYetLabel = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, sellersTableView.frame.size.width, [self heightForTableView])];
noSellersYetLabel.text = #"no sellers yet";
noSellersYetLabel.textAlignment = NSTextAlignmentCenter;
noSellersYetLabel.textColor = [UIColor grayColor];
[cell addSubview:noSellersYetLabel];
sellersTableView.separatorStyle = UITableViewCellSeparatorStyleNone;
}
}
removing
- (void) textFieldDidEndEditing:(UITextField *)textField
{
if (textField == addSellerTextField) {
[self updateSellers:textField];
}
}
- (void)updateSellers:(UITextField *)textField
{
[textField resignFirstResponder];
[self hideSellersTableView];
}
- (void)hideSellersTableView
{
[UIView animateWithDuration:0.3 delay:0 options:UIViewAnimationOptionCurveEaseIn animations:^{sellersTableView.layer.opacity = 0;} completion:nil];
sellersTableView.dataSource = nil;
sellersTableView.delegate = nil;
[sellersTableView removeFromSuperview];
sellersTableView = nil;
}
Solution
So apparently putting the dataSource = nil and delegate = nil into textFieldDidEndEditing fixed the problem. Thanks everybody for the answers!
It's strange behaviour of UITableView. The easiest way to resolve this issue just set the dataSource and delegate property of UITAbleView to nil before you make a call of function popToRootViewControllerAnimated. Furthermore you can use more common solution and add the code that set the properties to nil into the -dealloc method. In addition you no need the -killScroll method.
After a short research I have realized what the problem is. This unusual behaviour appeared in iOS 7. The scroll view retained by its superview may send message to delegate after the delegate is released. It happens due to -removeFromSuperview implementation UIScrollView triggers -setContentOffset: and, eventually, send message to delegate.
Just add following lines at the beginning of dealloc method:
sellersTableView.delegate = nil;
sellersTableView.dataSource = nil;
No need to use hacks like your killScroll method.
Also, I can't see why you want to call both popToRootViewController and dismissViewController.
If you dismiss a view controller which is embedded in a navigation controller, navigation controller itself as well as all contained view controllers will be released.
In your case you'll have just weird animation.
setContentOffset method won't help you, try to set
sellersTableView.dataSource = nil;
somewhere in your viewWillDisappear method.
This is not a good practice of course.
Change you closeViewController like below and see if works
(void) closeViewController
{
sellersTableView.dataSource = nil;
sellersTableView.delegate = nil;
[self.navigationController popToRootViewControllerAnimated:YES];
[self dismissViewControllerAnimated:YES completion:nil];
}
I don't think that setting the tableView (or it's delegate) to nil is the issue. You should be able to perform both dismissViewControllerAnimated or popToRootViewController individually without having to modify the tableView in this way.
So the issue is most likely due to calling both of these methods at the same time (and with animated = YES), and in doing so asking your viewController setup to do something unnatural.
Looks like upon tapping a "close" button you are both popping to a rootViewController of a UINavigationController, as well as dismissing a modal viewController.
In doing so, you're dismissing a modal viewController which is likely presented by the topViewController of the navigationController (so top vc is holding a reference to modal vc). AND you're trying to kill the top vc via the popToRootViewController method call. And you're doing both of these things using animated = YES, which means they take some time to complete, and you can't be sure when each finishes (ie you can't be sure when dealloc will be called).
Depending on your needs you could do one of several things.
Consider adding a delegate property to your modal vc. Dismiss the modal vc, and in the completionBlock of the modal vc tell its delegate that it's finished dismissing. At that point call popToRootViewController (because at this point you can be sure that the modal is gone and scrolling wasn't interrupted).
If it's your navController that's been presented modally, then do this in the opposite order. Notifying the delegate that the pop operation has completed, and do the modal dismissal then.
In my app I have this hierarchy:
AppViewController (root)-->HUDViewController (as a container viewcontroller within AVC)-->NavBar (subview of UIView)-->UIButtons
When you touch some of the buttons they need to launch a UIPopoverController from AVC. I send a notification back from the NavBar class to AVC. In the selector for the notification center I have this code
...
//get the client list from the notification
[dictPopoverData setObject: [[notification userInfo] objectForKey:#"Client List"] forKey:#"Client List"];
//get the frame of the object launching the popover
popupCallerFrame = CGRectFromString([[notification userInfo] objectForKey:#"Caller Frame"]);
[self presentPopOver:CLIENT_LIST:YES:dictPopoverData];
...
then in presentPopOver I have this:
- (void) presentPopOver : (int) popoverID : (BOOL) isTable : (NSMutableDictionary*) dictPopoverData {
if (self.myPopoverController != nil) {
[self.myPopoverController dismissPopoverAnimated:YES];
self.myPopoverController = nil;
}
CGRect launchFrame;
//init the popover
if (popoverID == CLIENT_LIST) {
ClientListPopover* vcClientList = [[ClientListPopover alloc] initWithStyle:UITableViewStylePlain];
vcClientList.arrDataSource = [dictPopoverData objectForKey:#"Client List"];
self.myPopoverViewController = vcClientList;
//set the launch frame
launchFrame = popupCallerFrame;
launchFrame.origin.x = launchFrame.origin.x;
launchFrame.origin.y = launchFrame.origin.y + 100.0;
} else if (popoverID == PA_LIST) {
PAListPopover* vcPAList = [[PAListPopover alloc] initWithStyle:UITableViewStylePlain];
vcPAList.strClientNumber = [dictPopoverData objectForKey:#"Client Number"];
self.myPopoverViewController = vcPAList;
//set the launch frame
launchFrame = popupCallerFrame;
launchFrame.origin.x = launchFrame.origin.x;
launchFrame.origin.y = launchFrame.origin.y + 100.0;
}
//init and display the popover controller
if (self.myPopoverController == nil) {
//add the self.myPopoverViewController
self.myPopoverController = [[UIPopoverController alloc] initWithContentViewController:self.myPopoverViewController];
//display the popover
[self.myPopoverController presentPopoverFromRect:launchFrame inView:self.view
permittedArrowDirections:UIPopoverArrowDirectionUp
animated:YES];
[self.myPopoverController setDelegate:self];
} else {
[self.myPopoverController dismissPopoverAnimated:YES];
self.myPopoverController = nil;
}
}
So what is suppose to happen is the user clicks the client button, notification gets sent to AVC, a UITable in a popover controller is presented. The user then selects a client from the table. Again, a notification is sent to AVC, the displayed client list popover should now be dismissed and the PA list popover should show. It seems that [self.myPopoverController dismissPopoverAnimated:YES] is not being called. I've traced it and it hits that line of code but nothing happens, the first popover remains on the screen. Any ideas of what I am doing wrong?
Edit: I forgot to mention I can't seem to assign a delegate to self.myPopoverController. Which is probably why the dismiss method is not firing.
Edit: I added the call to the delegate after the popover controller is inited. That didn't seem to make a difference. If I touch outside the first popover, without touching inside, it does dismiss and I can trace the method.
I have an universal app where I successfully upgraded the iPhone component to ios7.
The ipad component however is not running anymore. I get the following error:
Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[UISplitViewController tabBar]: unrecognized selector sent to instance 0x8d9eef0'
I have no idea what happened. I did not touch the ipad side of things whatsoever.
I am running: 11A4449d build and 5A11365y build for x-code on a mac machine.
After this code the error happens:
- (void) awakeFromNib {
[super awakeFromNib];
// whenever I come out of a storyboard, I make myself the delegate of any splitview I am in
self.splitViewController.delegate = self;
}
In this method: I set the selected image on a tab bar for the iPhone.
But did not realise that the iPad will not like it. So I put a selective statement (if !iPad) around it to fix it.
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
BOOL piPad = (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad);
if (!piPad)
{
// **************************************************************************************************
// Assign tab bar item with titles and selected images
UITabBarController *pTabBarController = (UITabBarController *)self.window.rootViewController;
UITabBar *pTabBar = pTabBarController.tabBar;
UITabBarItem *pTabBarItem0 = [pTabBar.items objectAtIndex:0];
pTabBarItem0.title = #"List";
pTabBarItem0.selectedImage = [UIImage imageNamed:#"tabBarList_30x30_selected"];
pTabBarItem0.image = [UIImage imageNamed:#"tabBarList_30x30.png"];
// **************************************************************************************************
}
return YES;
I have the following code to display a magazine type app. When the app is rotated it runs this code. I made sure that it is only run when rotated to supported orientations. When this function returns, the app fails with a SIGABRT. There is no other indication as to why.
I know it's this function because when I remove it the program does not fail.
- (UIPageViewControllerSpineLocation)pageViewController:(UIPageViewController *)pageViewController
spineLocationForInterfaceOrientation:(UIInterfaceOrientation)orientation
{
//If portrait mode, change to single page view
if(UIInterfaceOrientationIsPortrait(orientation)){

NSArray *viewControllers = [NSArray arrayWithObject:currentViewController];
[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];
self.pageViewController.doubleSided = NO;
return UIPageViewControllerSpineLocationMin;
//If landscape mode, change to double page view
}else{

Alas, borrrden is probably right. One of your IBOutlets is probably missing from your XIB. Make sure ALL of your IBs are connected properly, and if the problem continues, say so.
Well you didn't provide the output from the console, which would be nice. Giving the code a quick look I would guess that one of your controllers (next or previous) is nil, and since you can't insert nil into an NSArray (except as the last object) it is throwing an error.
EDIT Well, my guess was wrong. The error message is saying that the UIViewControllers you are giving to it do not support the orientation that the page controller needs. This is because you have a method called shouldRotateToInterfaceOrientation: in your child UIViewControllers, and they are returning no for (in this case) left landscape.
I was getting the same error
Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'All provided view controllers ((
"<ContentViewController: 0x6a7eac0>",
"<ContentViewController: 0x6d89f10>"
)) must support the pending interface orientation (UIInterfaceOrientationLandscapeLeft)'
Adding the following to my PageModel class, where the page layout is designed worked for me:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
