I have added the popOvercontroller on click of navigation bar right button.i don't want the animation effect..can anybody tell me how to disable it???
There are two pieces to this. Using presentPopoverFromBarButtonItem:permittedArrowDirections:animated:NO or presentPopoverFromRect:permittedArrowDirections:animated:NO to present the popover will prevent the "appearing" animation. To disable the disable the "disappearing" I had to add this to the delegate:
- (BOOL) popoverControllerShouldDismissPopover:(UIPopoverController *)popover {
// Any cleanup code (popoverControllerDidDismissPopover won't be called)
[popover dismissPopoverAnimated:NO];
return NO;
}
How do you instantiate it? the docuemntation mentions presentPopoverFromBarButtonItem:permittedArrowDirections:animated: - sounds like the perfect answer to your question.
Btw. if you're showing a popover from a table view, you'll want to animate row deselection at the same time while popover is being dismissed. To achieve this, you can use:
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popover {
[self.tableView deselectRowAtIndexPath:[self.tableView indexPathForSelectedRow] animated:YES];
[popover dismissPopoverAnimated:YES];
return NO;
}

I don't want to dismiss popover controller when i touch any view. Is it possible?
I am using following code for displaying popover controller.
UIPopoverController* popoverCamera;
popoverCamera= [[UIPopoverController alloc] initWithContentViewController:videoRecorder];
[popoverCamera presentPopoverFromRect:CGRectMake(cropRectangleButton.frame.origin.x,cropRectangleButton.frame.origin.y,0,0) inView:innerview permittedArrowDirections:UIPopoverArrowDirectionUp animated:YES];
NSLog(#"start recording-->%d",[videoRecorder startVideoCapture]);
[videoRecorder startVideoCapture];
[self presentModalViewController:videoRecorder animated:YES];
[videoRecorder release];
Yes it is possible. Implement the following delegate method:
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController
{
return NO;
}
Hope this might help you.
From the Link disable dismissal of uipopoverview controller
When displayed, taps outside of the popover window cause the popover to be dismissed automatically. To allow the user to interact with the specified views and not dismiss the popover, you can assign one or more views to the passthroughViews property. Taps inside the popover window do not automatically cause the popover to be dismissed. Your view and view controller code must handle actions and events inside the popover explicitly and call the dismissPopoverAnimated: method as needed.
implement the pop over delegate
/* Called on the delegate when the popover controller will dismiss the popover. Return NO to prevent the dismissal of the view.
*/
- (BOOL)popoverControllerShouldDismissPopover:(UIPopoverController *)popoverController;
func popoverShouldClose(_ popover: NSPopover) -> Bool {
return false
}
Try this where you dont want to dismiss the popUp:-
[popOverController dismissPopoverAnimated:NO];
Hope this helps :)
I've been trying to learn the new Storyboard feature in Xcode and I've run into a problem with trying to set a UITableView to edit mode.
So far my storyboard looks like this:
NavigationController -> UIViewController (subclass with tableview property)
I added a Navigation Item and a Bar Button item to the view controller scene, so I do see an edit button. It didn't do anything automagically, so I tried linking it's selector to the setEditing method of the tableview delegate. This did put it into editing mode. However, the edit button did not change to a "Done" button and so there is no way to get out of editing mode.
Do I have to create another Navigation item for the Done button? How do I connect it so that it appears at the right time and works correctly?
I think that also with Storyboard, the only way (for sure, the easiest one) to implement a working edit/done button, is to use the following code:
- (void)viewDidLoad
{
[super viewDidLoad];
...
//set the edit button
self.navigationItem.leftBarButtonItem = self.editButtonItem;
...
This is the solution that Apple itself implements if you select a "Master-Detail Application" template for your project.
Probably Storyboard is still not perfect, and hopefully it will be improved from Apple in next releases...
I just started using Storyboards, so I also wanted to use the Storyboard to add my Edit button. It is annoying to have taken the time to learn how to use a new tool but find you need a roll of duct tape to patch up the holes.
You can get it to work, but need to add a Custom button. In the Attributes inspector make sure the Identifier is Custom and the title is Edit.
Then add something like this in your .m
- (IBAction)setEditMode:(UIBarButtonItem *)sender {
if (self.editing) {
sender.title = #"Edit";
[super setEditing:NO animated:YES];
} else {
sender.title = #"Done";
[super setEditing:YES animated:YES];
}
}
Have your Custom Edit button call the setEditMode method.
Can only hope they will fix the implementation of the Edit button in the Storyboard editor in the future.
To summarize:
The Button, returned by UIViewController.editButtonItem is a special toggling button with special behavior that calls - (void)setEditing:(BOOL)editing animated:(BOOL)animated if pressed.
The Button, returned by UINavigationController.editButtonItem is a simple Button, just labeled with "Edit".
The Storyboard allows to select the latter one.
If you are using the navigation controller to push to the view controller, simply set self.navigationItem.rightBarButtonItem = self.editButtonItem;, which will put the default Edit button in the right. If the navigation bar is not visible, call self.navigationController.navigationBarHidden = NO;. Those would be called in the viewDidLoad method, or something similar. Then in order to get the tableView to respond to the edit call, use the following method:
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[tableView setEditing:editing animated:animated];
}
That should do what you want it to do. If you have any issues, just say so and we can narrow down the details
To add to #Graham answer, you might also want to change the style so you can have the "Done" button style (the blue color). Something like this:
- (IBAction)setEditMode:(UIBarButtonItem *)sender {
if (self.editing) {
sender.title = #"Edit";
sender.style = UIBarButtonItemStylePlain;
[super setEditing:NO animated:YES];
} else {
sender.title = #"Done";
sender.style = UIBarButtonItemStyleDone;
[super setEditing:YES animated:YES];
}
}
one can use the dumb, not working Edit button from the Storyboard editor and then programmatically replace it with the UIViewController.editButtonItem.
in viewDidLoad:
NSMutableArray *toolbarItems = [NSMutableArray arrayWithArray:self.toolbarItems];
[toolbarItems replaceObjectAtIndex:0 withObject:self.editButtonItem];
[self setToolbarItems:toolbarItems];
this code assumes one has added the dumb Edit button as the leftmost item on the toolbar in the Storyboard.
In case that you have UIViewController and inside this you added a UITableVIew.
If you want to add an edit UIBarButton in order to interact with UITableView, try:
Add this line...
- (void)viewDidLoad
{
[super viewDidLoad];
...
self.navigationItem.leftBarButtonItem = self.editButtonItem;
...
}
and this method
- (void)setEditing:(BOOL)editing animated:(BOOL)animated {
[super setEditing:editing animated:animated];
[self.myListTableView setEditing:editing animated:animated];
if(self.myListTableView.editing) {
NSLog(#"editMode on");
} else {
NSLog(#"editMode off");
}
}
where
#property (weak, nonatomic) IBOutlet UITableView *myListTableView;
I added a modalView to my App, everything working fine, but on closing the modal, the whole modalView jumps about 1-2 centimeters to left while it disappears.
I did not find any reason for it yet, so here is the code regarding modal:
AppController:
- (void) showNameModal:(Player *)player
{
namesModal = [[PlayerModalView alloc] init];
namesModal.delegate = self;
namesModal.player = player;
UINavigationController *navCon = [[UINavigationController alloc] initWithRootViewController:namesModal];
navCon.modalPresentationStyle = UIModalPresentationFormSheet;
[self presentModalViewController:navCon animated:YES];
[navCon release];
[namesModal release];
}
- (void)didDismissModalView
{
[self dismissModalViewControllerAnimated:YES];
}
ModalView:
- (void)dismissView:(id)sender
{
[delegate didDismissModalView];
}
called via navigation buttons as well ass via keyboard by
[self dismissView:nil];
As you can see, there is nothing special in it, could be taken from a manual actually.
What happens in detail:
Modal appears in center of screen, slides in from the bottom. centered all time.
i can handle some actions in the modalView, it stays centered.
now, dismissing the view makes it jumping to the left, than slides out.
Since it's a forced landscape-right app (currently), I was only able to notify the left-jump.
Any ideas how to get this jumping away?
Thanks
Try this,
- (void)didmissView:(id)sender
{
[self.navigationController didmissModelViewControllerAnimated:YES];
}
You are not modally presenting an instance of PlayerModalView but rather a UINavigationController. The left jerk you see is most likely the default animation of the navigation controller attempting a slide transform to the (non-existant) previous view.
It doesn't sound like you need a navigation controller for the PlayerModalView. Instead, you should create an ordinary view controller for it.
This solution seems to work well: Modal View Controller with keyboard on landscape iPad changes location when dismissed
To simplify resigning the first responder (if finding it is difficult), you can just call
[self.view endEditing:YES];
[self dismissModalViewControllerAnimated:YES];
The problem is that the UIViewController you're showing modally doesn't allow the orientation you're presenting it in, so when it disappears, it will do that in a direction that it considers "allowed".
Add this to the UIViewController for you modal view:
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return YES;
}
I have a UISearchDisplayController setup with a UITableViewController which is nested inside a UINavigationController. When a selection of a cell is made, UITableView's didSelectRowAtIndexPath method is triggered, which pushes a new view to the parent navigation controller. This new view should have the navigation bar hidden on entry.
[[self navigationController] setNavigationBarHidden:YES animated:NO];
I use this line in the didSelectRowAtIndexPath method to hide the navigation bar. This works fine when a row is selected not using the search controller, but is overridden when selecting a search result. It seems the UISearchDisplayController takes it in its right to un-hide the navigationBar sometime after the row is selected.
If I move the setNavigationBarHidden call into the target view's viewWillAppear method, results are similar. I can make it work by placing the hide call in viewDidAppear, but this makes for a very awkward transition effect which feels jumpy and out of place. I would like to make the navigationBar already hidden before the new view slides on to the screen.
Does anyone know where the unhiding of the navigationBar is occurring, and/or any way I can override this behaviour?
This may not be the most elegant solution, but I believe it does exactly what you'd want it to. I came across a similar problem, and my solution was to have a method which hides the navigation bar, which is called after a delay of 0 seconds as follows.
The method that is called is:
-(void) hideNavBar {
if (self.navigationController.navigationBar.hidden == NO)
{
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
}
Then in the viewDidLoad method, I have the following:
[self performSelector:#selector(hideNavBar) withObject:nil afterDelay:0.0];
This works and removes the navigation bar in one instantaneous swoop. You can amend the delay time if you want the animation or for it to be removed after a delay. I tried [self hideNavBar] but that simply did not work, so sticking to what I have above.
Hope this helps, and if someone has a more elegant solution, I'm interested!
Ok, this bugged me for the a couple of hours, but I finally got it to work! The problem seems to be that the UISearchDisplayController keeps track of whether or not it has hid the navigation bar, and if it has, it restore it, after the view has been dismissed. That is why with many of the answers above you see the tail end of the animation of the bar hiding itself when the new view is pushed. However, by tricking the search display controller we can change this behavior.
First: Subclass The UISearchDisplayController
Following the answer on how to keep a navigation controller from hiding, found here, I altered the code, to keep the navigation bar hidden:
- (void)setActive:(BOOL)visible animated:(BOOL)animated
{
if(self.active == visible)
return;
[self.searchContentsController.navigationController setNavigationBarHidden:YES animated:YES];
[super setActive:visible animated:animated];
if (visible)
[self.searchBar becomeFirstResponder];
else{
[self.searchBar resignFirstResponder];
[self.searchContentsController.navigationController setNavigationBarHidden:NO animated:YES];
}
}
Note we hide the navbar before we call the super setActive function. This seems to keep the super class from trying to hide the nav bar and consequently, from trying to restore it ater item selection. Now when the controller becomes active, the bar will be hidden like normal. Also note that we restore the navigation bar when the searchBar resigns first responder. This will restore the bar if we cancel out of the controller.
Second: Hide Navigation Bar When Exiting
If we hide the navigation bar in the view will disappear, it will be hidden:
-(void)viewWillDisappear:(BOOL)animated{
[super viewWillDisappear:animated];
[self.navigationController setNavigationBarHidden:YES animated:animated];
}
Third: Hide Navigation Bar When Returning
The only problem now is that if we select a row from the filtered tableview, when we return, the navigation bar will be visible. To fix this we need to put a check in view will Appear:
- (void)viewWillAppear:(BOOL)animated
{
[super viewWillAppear:animated];
if(self.isFiltered){
[self.navigationController setNavigationBarHidden:YES animated:NO];
}
}
While this feels like a huge hack, it does the trick and I could see no better way of doing it.
Bumped into the same problem, managed to get it working smoothly with this ugly hack:
- (void) viewWillDisappear: (BOOL) animated
{
if (searchController_.active)
{
self.navigationController.navigationBar.barStyle = UIBarStyleBlackTranslucent;
self.navigationController.navigationBar.tintColor = nil;
}
[super viewWillDisappear: animated];
}
- (void) viewWillAppear: (BOOL) animated
{
if (searchController_.active)
{
self.navigationController.navigationBar.barStyle = UIBarStyleDefault;
}
[super viewWillAppear: animated];
}
I had the same problem: my view has the navigation bar hidden by default and here's the way to keep it hidden:
-(void) viewWillLayoutSubviews{
if (self.navigationController.navigationBar.hidden == NO)
{
[self.navigationController setNavigationBarHidden:YES animated:YES];
}
}
This way the navigation bar doesn't appear even after the search bar has been used.
- (void) viewWillDisappear: (BOOL) animated
{
// self.searchOn property tell if full screen search is enabled
//if (self.searchOn)
//{
[self.navigationController setNavigationBarHidden:NO animated:NO];
//}
[super viewWillDisappear: animated];
}
- (void) viewWillAppear: (BOOL) animated
{
//if (self.searchOn)
//{
[self.navigationController setNavigationBarHidden:YES animated:YES];
//}
[super viewWillAppear: animated];
}
I have an iPhone app that is based on a navigation controller.
I have a main view controller that displays a list of articles, and a detail view, where you can see one article in a UIWebView. For the detail view, I have the navigation bar on the top, and a UIToolbar on the bottom.
I'd like to auto-hide them with a slide animation (to top and bottom) and restore them when tapping the screen. I thought this would be a standard function, but couldn't find how to do it.
As a reference, this is what Stanza or the NYT app do.
Set up a method that runs this on a tap event:
if (![navigationController isNavigationBarHidden])
[navigationController setNavigationBarHidden:YES animated:YES]; // hides
else
[navigationController setNavigationBarHidden:NO animated:YES]; // shows
As for the UIToolbar, it is a UIView subclass, so you should be able to pretty easily set up a custom animation for sliding this in and out of sight.
There is also quite a useful method for UIVIewController.
- (BOOL) hidesBottomBarWhenPushed {
//hide a toolbar or whatever
return NO;
}
Try this:
BOOL hide = ![self.navigationController isNavigationBarHidden];
[self.navigationController setNavigationBarHidden:hide animated:YES];
I guess recently you can use self.navigationController.hidesBarsOnTap = true;
