I am using MMDrawerController for making left slide menu in iOS. The problem is that all the view controllers I am using in this project are having slider with them i.e in each UIViewController I can slide to get left menu but I want only with the first view not with all the UIViewController.
How can I stop slider code for the other UIViewController in the project.
you can cancel panning using below method. put that method in viewWillAppear
To allow gesture add this in viewWillAppear
[self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeAll];
when you push any view cancel gesture using below code.
[self.mm_drawerController setOpenDrawerGestureModeMask:MMOpenDrawerGestureModeNone];
if you don't want side menu for a view controller, call it using segue
example issue code:
assuming you have used this code in the side menu to navigate to other view controllers
switch(item selected) ....
case number:
centerViewController = [self.storyboard instantiateViewControllerWithIdentifier:#"STORYBOARD_ID"];
instead use :
[self performSegueWithIdentifier:#"segue_identifier" sender:nil];
this will navigate to completely new context instead of adding your view controllers to the centerViewController of MMDrawerController

I create a UINavigationController (as a initial screen) and connect them with my UITableViewController (as a root).
Next, I create another UINavigationController and connect with my UIViewController. Inside my UITableViewController I connect my first cell with UINavigationController (That was connected with my UIViewController) (Segue -> show).
When I run the project my table appears, when I select my first row, my UIViewController appears. Thats great!
When I was in my UIViewController the back bar button doesn't appears, in my case I create a left bar button, that will run a function to dismiss that view and go back to my UITableViewController, for that I use many codes:
-(void)back{
NSLog(#"Called");
[self.parentViewController.navigationController popViewControllerAnimated:YES];
}
-(void)back{
NSLog(#"Called");
[self.navigationController popViewControllerAnimated:YES];
}
-(void)back{
NSLog(#"Called");
[self.navigationController popViewControllerAnimated:YES];
}
But all of they doesn't works and my view don't dismiss, how can I solve this problem?
The problem is that your navigation controller, that you call from your table view cell, has only a single view controller (yours) on its navigation stack. So it cannot pop anything from this stack, else the stack were empty.
What you have to do instead is to dismiss the navigation controller itself.
I think that the solution would be to remove the second navigation controller. Since the TableView is already embedded inside a Navigation Controller, the show segue to the UIViewController must be directly connected to it.
I am working on a new project of mine and am looking for what the best solution to keep the UITabBarController displaying even when using a segue to push to a UIViewController.
Currently I have an Initiation of our UITabBarController on app launch, which contains multiple viewcontroller relationships. Particularly the initial view controller option is a custom UIViewController which implements a UITableView. Once a cell is selected I call a show(push) segue to another UIViewController. This is where I lose my TabBar which is as expected. Now I have tried different approaches such as setting the hidden value of our tabbar to YES, but does not seem to help.
Code
When Cell Selected:
[self performSegueWithIdentifier: #"tableCellOptions" sender: self];
When preparing for segue:
if([segue.identifier isEqualToString:#"tableCellOptions"]) {
additionUITableView *move = (additionUITableView *) segue.destinationViewController;
move.thisOption = [menuOptions objectAtIndex:cellPushed];
}
What would your approach be to this and why?
If you have Tab bar controller as the initial View Controller, the tab bar will show by default on each view controller.
If you are using storyboard or xib file, then select the tab bar item in view controller and check its properties, and make sure "hide tab bar on push" is unchecked.
Programmatically you can do this,
self.hidesBottomBarWhenPushed = NO;
[self.navigationController pushViewController:viewControllerToPush animated:YES];
Place it in viewDidLoad or viewDidAppear.
I hope this solves your problem.
I have a functioning app, and I'd like to just add a new view and have an existing button change views with an IBAction function. I've set up the following and get no response. Thanks for any help.
MainViewController.h
- (IBAction)showSettings:(UIButton *)sender;
MainViewController.m
-(void)showSettings:(UIButton*)btn{
SettingsViewController *oView = [[SettingsViewController alloc] initWithNibName:#"SettingsViewController" bundle:nil];
[self.navigationController pushViewController:oView animated:YES];
}
SettingsViewController.h (the new view) is relatively empty.
SettingsViewController.m
boilerplate
Three things to make sure:
showSettings: gets called when the button is tapped (if not then perhaps you didn't connect the button tap event to the action at all)
SettingsViewController instance gets alloc and initialised
self.navigationController is not nil (if it's nil perhaps the current view controller is not embed in a navigation controller in the first place?).
Update:
Now we see the issue is #3. To embed your first view controller to a UINavigationController so you could push the second view controller:
Select your first view controller in storyboard
Select (menu) Editor -> Embed In -> Navigation Controller
Have you wired up your button's TouchUpInside event to your showSettings: method? This is normally done in Interface Builder with a control-drag. If you set a breakpoint on the first line of showSettings:, do you hit the breakpoint when you press the button? If not this is likely your issue.
I have a view controller. When I press a button in it, a popover controller with a uitableview shows up. I select a row, which shows another view with some controls in it. When I press a button that says "Save Item", I want it to dismiss the popover. How do I do this?
Here's what I've tried:
Using the delegate and protocol pattern. This hasn't worked since in order to push another view inside my tableview, the whole thing must be embedded in a navigation view controller, so when I segue, it segues to a nav controller, not the tableview which I could set the popover delegate for.
Adding my main view as a member of the view I want to dismiss from. I don't know why this doesn't work.
The Hard Clean Way
There are four view controllers in the story, plus a popover controller. I will call the three view controllers "main view controller", "nav", "vcA", and "vcB". As I understand it, "nav" is the initial content view controller of the popover and has "vcA" as its root view controller.
main view controller -> popover controller -> nav -> vcA -> (later) vcB
When you present the popover from your main view controller, you keep a reference to the popover controller. This is what makes dismissing possible, as you know.
When you create the Save button, you make its target the main view controller and its action a method in the main view controller. You will have to set this up in code; it cannot be configured from a storyboard because you cannot form an action from one scene to another. (You are able to do this because you started out with a reference to nav and vcA when you configured the popover controller initially. Thus you can hand vcA a reference to self, the main view controller. If necessary, you can then pass this reference down the chain from vcA to vcB as vcB is summoned and pushed onto the navigation stack.)
Now the user taps Save, your main view controller's method runs, and it uses its reference to the popover controller to tell it to dismiss.
The Easy Dirty Way
The heck with all that. The main view controller registers for an NSNotification. The Save button posts that NSNotification. Done. :)
The Middle Way
You could set the whole chain up in your storyboard using a popover segue, and do the dismissal through an Unwind segue matched by an unwind method back in the main view controller. I never think of this initially, because I don't like popover segues very much. But it does work.
This is how I solved my problem (sorry for the bad english):
First, Create a property of UIStoryboardPopoverSegue in the VcA and set it from the main view controller.
Nav -> VcA_ViewController
#property (strong, nonatomic) UIStoryboardPopoverSegue *popupSegue;
Then, in the Main View Controller prepareForSegue set the property:
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender{
if([segue.identifier isEqualToString:#"your segue from the mainview to the navigation"]) {
UINavigationController *navigationController = (UINavigationController *)c;
VcA_ViewController *vcA = (VRPointOfInterestsFiltersViewController *) navigationController.topViewController;
vcA.popupSegue = (UIStoryboardPopoverSegue*)segue;
} }
Now, from the VcA controller you can have the dismiss button
- (IBAction)dismissPopoup:(id)sender {
[self.popupSegue.popoverController dismissPopoverAnimated:YES]; }
Don't forget to link the popOverSegue from the MainViewController to the NavController.
Hope it helps!
I'm trying to use a popover as an intermediary menu between my main view and a modal view controller. I can successfully present the Modal view controller from the popover by using the following code:
UIStoryboard *storyboardiPad = [UIStoryboard storyboardWithName:#"MainStoryboard_iPad" bundle:nil];
cbwEditControlPanel *editCP = [storyboardiPad instantiateViewControllerWithIdentifier:#"EditCP"];
UINavigationController *nav = [[UINavigationController alloc] initWithRootViewController:editCP];
[nav setToolbarHidden:NO];
[nav setModalPresentationStyle:UIModalPresentationFullScreen];
[nav setModalTransitionStyle:UIModalTransitionStyleCoverVertical];
[self presentViewController:nav animated:YES completion:nil];
self.modalInPopover = NO;
The problem I'm running into is that when the EditCP modal view controller is dismissed, the main view controller never updates. I have a pagecontroller on the main view that should be updated to reflect the number of pages as set in the EditCP modal view controller, but for some reason the modal view controller being called from the popover prevents the main view controller from updating the pagecontroller. I've even tried calling the main view's "View Will Appear" method from the popover or modal view when they are dismissed, but even if the 'viewWillAppear' method is called the pageController will not update!
Any ideas what is preventing the pageController from updating? I even passed a reference to the pagecontroller to the modal view and tried to update it there, but it seems that from the time the popover is presented until it is dismissed, I cannot update the number of pages on the PageController.
Thank you!
So this is an old question but I also came across a similar problem recently when using a popover. My solution was to use an unwind segue to trigger my parent view to perform some action. In my case my parent view contains contact information and the popover contains a list of cites. All I wanted to do was to have the parent view update with the new city once the user selected it from the popover. So in my parent view I create my unwind function as follows:
In the .h:
- (IBAction)unwindToContactTVC:(UIStoryboardSegue *)unwindSegue;
In the .m:
- (IBAction)unwindToContactTVC:(UIStoryboardSegue *)unwindSegue
{
[self updateTableForOffice];
}
In the above .m file is where you would have the logic to do whatever it is you want to in the parent view. To connect this unwind segue go to the child view in the storyboard and control drag from the view icon to the exit icon. You should see a pop up with the name of your unwind segue.
Finally, give that unwind segue a name and then in the child controller in the viewWillDisappear() function call the segue as follows:
- (void)viewWillDisappear:(BOOL)animated
{
[self performSegueWithIdentifier:#"unwind-to-contact-tvc" sender:self];
}
I hope that helps. If someone has a better solution let me know.
Well, I half solved the problem. The only way to get an update function when the popover disappeared was to stop using Storyboards and programmatically present the popover, using the main view as the delegate. I then was able to update correctly inside the popoverControllerDidDismissPopover method.
However, I am still interested in finding a way to update the pageControl when the modal is dismissed, before the popover is dismissed.
