I'm not able to hide navigation bar even using [self.navigationController setNavigationBarHidden:YES];

I also have commented code which is responsible to draw SegmentButtons.

Hi Folks,

I am willing to perform a custom action when I swipe left from the first controller.

In that case, there should be no controllers to the left and if that's true, I'd like to recognize it and make a custom action. Is that possible?

Thanks,

Hi Richard,
I dragged .h and .m files into my directory and an error said "cannot find protocol declaration for NSObject". I checked that the @protocol RKSwipeBetweenViewControllersDelegate following with a <NSObject>. After deleting that everything was fine.

Hi,

I have the following structure:

SignUpViewController ---PRESENT MODAL---> MainViewController

i call RKSwipeBetweenViewControllers inside viewDidLoad() from MainViewController.

• (void)viewDidLoad {
  [super viewDidLoad];

  self.window = [[UIWindow alloc] initWithFrame:UIScreen.mainScreen.bounds];

  pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];
  navigationController = [[RKSwipeBetweenViewControllers alloc]initWithRootViewController:pageController];
  self.scrollViewGeneral = [navigationController getUIScrollView];
  [myManager setMyGeneralVC:self];

  UIStoryboard _storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
  UIViewController_vc1 = [storyboard instantiateViewControllerWithIdentifier:@"myVC1"];
  UIViewController_vc2 = [storyboard instantiateViewControllerWithIdentifier:@"myVC2"];
  UIViewController_vc3 = [storyboard instantiateViewControllerWithIdentifier:@"myVC3"];
  UIViewController*vc4 = [storyboard instantiateViewControllerWithIdentifier:@"myVC4"];

  [navigationController.viewControllerArray addObjectsFromArray:@[vc1, vc2, vc3,vc4]];

  self.window.rootViewController = navigationController;
  [self.window makeKeyAndVisible];
  }

It works fine.
I created a button "disconnect" to come back to SignUpViewController.
I must dismiss ViewControllers (myVC1, myVC2, myVC3, myVC4) and also the MainViewController.

i tried this from MainViewController:

-(void)dismissView
{
UIStoryboard _storyboard = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController_vc1 = [storyboard instantiateViewControllerWithIdentifier:@"myVC1"];
UIViewController_vc2 = [storyboard instantiateViewControllerWithIdentifier:@"myVC2"];
UIViewController_vc3 = [storyboard instantiateViewControllerWithIdentifier:@"myVC3"];
UIViewController*vc4 = [storyboard instantiateViewControllerWithIdentifier:@"myVC4"];

//FIRST TRY
[vc1.navigationController popViewControllerAnimated:NO];
[vc2.navigationController popViewControllerAnimated:NO];
[vc3.navigationController popViewControllerAnimated:NO];
[vc4.navigationController popViewControllerAnimated:NO];

//SECOND TRY
[vc1.navigationController dismissViewControllerAnimated:NO completion:nil];
[vc2.navigationController dismissViewControllerAnimated:NO completion:nil];
[vc3.navigationController dismissViewControllerAnimated:NO completion:nil];
[vc4.navigationController dismissViewControllerAnimated:NO completion:nil];
[self.navigationController dismissViewControllerAnimated:NO completion:nil];

//THIRD TRY

[vc1.navigationController popToRootViewControllerAnimated:NO];
[vc2.navigationController popToRootViewControllerAnimated:NO];
[vc3.navigationController popToRootViewControllerAnimated:NO];
[vc4.navigationController popToRootViewControllerAnimated:NO];
[self.navigationController popToRootViewControllerAnimated:NO];

}

It's not works.
thanks for help ;)

it seems RKSwipeBetweenViewControllers can run at appDelegate.m?

1. terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Duplicate states in queue
   when i click quickly Not adjacent button，it will happen.
   2.Removing a view controller from UIPageViewController
   when i swiping viewController and i click viewController'view'subviews at the same time,it will happen

It'd be really great if you use the Accelerometer and Gyroscope to swipe between the views with just a Clunk or a slight jerk. I've written a very nice wrapper around CoreMotion Framework too.

lets say i use a UIButton on first view controller and now i want to go to next controller on its action method.

Thanks

Hey @cwRichardKim

Thanks for creating and sharing this!!!

I was able to port it into Swift with behavior that is more like Tinder located at:

https://github.com/jonathanxie/JXSwipeBetweenViews/blob/master/README.md

Might be a bit buggy but it works decently well...

Also, for the X_OFFSET issue, I noticed that it appears if you set the navigationView to the titleView of the navigationBar:

pageController.navigationController.navigationBar.topItem.titleView = navigationView;

Try setting the background color of the navigationBar to red and you can see that it's somehow smaller than the screen even though the self.navigationBar.frame.size.width is the same as the width of the screen.

Anyway, I set my navigationView to be a subview of the navigationBar and I didn't have the X_OFFSET issue. The X_OFFSET issue gets really annoying when I run the app on different devices on fullscreen mode instead of scalemode. Couldn't figure out an easy solution so I just did this:

 navigationBar.addSubview(navigationView)

I have a version of this in Objective-C using your code base. If you want me to put that up too for others who are still using Objective-C, let me know!

Hope this helps others out!

Apparently the button and selector position/size is not updated if the view rotates.

dirty workaround:

• (BOOL)shouldAutorotate
  {
  return NO;
  }

Is there any way this can be done just in a UIViewController or a page controller? I am not a fan of all this happening in the navigation controller because, if I were to segue some where and then tap on another tab in my tabbar and then return to the tab with this SwipeBetweenViewControllers, there are methods being called that should NOT be called since I am on another view controller in the navigation stack array(such as the delegate method). I understand why it is happening because there is a custom class for the navigation controller in the embedded navigation controller in the storyboard. Maybe I am making this entirely wrong. But if there is an example I am trying to copy, it is Instagram's News Feed. Looks identical to the custom library you have here. The swipe with the almost identical segmented control.

How to handle Page controller in RKSwipeBetweenControllers which is getting called Twice.

The setup code inside viewWillAppear should only be performed once. Inside my app it happens that I push a view controller and when navigating back viewWillAppear is called again. This then causes all the pages to be setup again and the current index is reset.

How to adjust height of the buttons/tabs?

your Tab bar is 'in' the navigation bar.

But I want to put it bottom at the sub viewcontroller...

Is it possible?

I'm grateful your project for nice performance swiping between viewcontrollers but 'RKSwipeBetweenViewControllers' is the subclass of NavigationController, not the UIViewController... That's my sorry point...

Can I put it there? Please help me

Is their a way to use it instead of UISegmentedControl in UISearchController. Or use it along a UISearchBar to make it similar? Please advise.

How to set a navigation title?

When set pageScrollView.bounces = NO
can't swipe Page

When I dismiss a modal within one of my view controllers, the swipe controller somehow resets back to the first view controller in the array. I've tried to set it back to the right view controller in the completion block of the modal dismissal, but that didn't work. Any ideas?

I just clone the project and run it in my Xcode 5.1.1
When I change the phone orientation to landscape. It look like the bar is not full-width support landscap:

I noticed when I move this view controller it drags in a multitude of directions besides up and down and I am assuming that is because of scrollview? Is there any way to stop it from moving diagonally? I am currently trying to stop the scrollview from moving in diagonal directions with every snippet of code I can find online. Could it be because I have auto layout turned on?

Hey,
i just wanted to inform you that I updated your project to add an unlimited number of tabs.

How to add back button in this ?

when i push the object of RKSwipeBetweenViewControllers
it crash.
code:
RKSwipeBetweenViewControllers *swipeVC = [RKSwipeBetweenViewControllers newSwipeBetweenViewControllers];
[nav_tweet.viewControllerArray addObjectsFromArray:@[[TimelineViewController newTimelineViewControllerWithType:TimelineViewControllerType_Nearby],
[TimelineViewController newTimelineViewControllerWithType:TimelineViewControllerType_Hot]]];
nav_tweet.buttonText = @[@"A", @"B"];
[self.navigationController pushViewController:nav_tweet animated:YES];

then it crash log is : NSScanner: nil string argument
how to fix it ?

Hi Sir,

First of all this is amazing and its easy to use, Thanks.

I would like to know how do i add a back button, because doing the same on the storyboard moves the name of the controllers to the right where i want to show the cancel or back button.

Also when i try to change the height of navBar to show my cancel button, the buttons are moved more upwards.
So now the changes has to be done in :

UIButton *button = [[UIButton alloc]initWithFrame:CGRectMake(X_BUFFER+i*(self.view.frame.size.width-2*X_BUFFER)/numControllers-X_OFFSET, Y_BUFFER, (self.view.frame.size.width-2*X_BUFFER)/numControllers, HEIGHT)];

 [navigationView addSubview:button];

Is there any other way around.

Thanks in Advance.

I found you use navigationBar . So the Tab button will put top at screen.
But I want to move the tab to the bottom. Can I move the navigation bar to bottom?
If I move the navigation bar to the bottom at screen, the Apple will reject the app?
Thank you.

So far, loving the implementation @cwRichardKim (plus checked out your other projects too and excited to try those out). Thanks for putting this together. How long did it take you?

I'm noticing

Unbalanced calls to begin/end appearance transitions

for in the console when I dismiss a viewcontroller that was presented via

    [self presentViewController:destinationVC
                       animated:YES
                     completion:nil];

Any help on this one?

The fact that you have to modify the implementation is completely ridiculous, because that negates all the advantages of using source control. If you push a change to git, there is no way for us to receive the update without manually adding it in ourselves in our heavily modified implementations. It would be much better if all of the private customization properties were exposed in the implementation so customization could be done from another class.

I appreciate your work here, but I think this library would be much better off if these changes were made.

I admit it's hard to tell what's going on by reading the title of this issue but I didn't know how to put it in a better way and I think it's severe.

To reproduce

• use only 2 view controllers in UIPageVIewController (that's the scenario I use).
• swipe to the second view controller and continue swiping but keep your fingers down on the display so that the highlight bar'x origin x position will continue to be larger than the center of the screen (in case of e.g. iPhone8 = 187.5).
• In order to reproduce it, it's important that you do not lift your finger after you started scrolling from the first to the second vc. If that's hard to do, keep pushing your first finger down on the display and use a second finger to scroll further.
• Once the highlight bar's x position is > 187.5 (in case of the iPhone 8) it will switch back to 0 and the highlight bar is in the position of the first view controller even thought the second vc is currently displayed.

@cwRichardKim any idea how to fix that?

Right now if you swipe right from the initial controller, it starts the animation even though there's nothing to swipe to. Is there a way to disable this animation?

the method 'syncScrollView' has this code below:
for (UIView* view in pageController.view.subviews){
if([view isKindOfClass:[UIScrollView class]])
{
pageScrollView = (UIScrollView *)view;
pageScrollView.delegate = self;
}
}

What I can not undestand is that how there is the view whose class is 'UIScrollView'
Programmer set pageController's viewcontrollers so there might not be a uiscrollview.
But it always pass that code 'if([view isKindOfClass:[UIScrollView class]])'
I don't understand

I'm trying to combine RKSBVC with a modal transition using UIViewControllerTransitioningDelegate. I want to access the cell they clicked on in the first page, but just instantiating the view controllers in appDelegate doesn't seem to setup a Parent-Child relationship.

Is there another way to init the slider so that it creates the right relationship with its Child Controllers?

Slide the half let go , quickly slide Next

i'm trying to add RKSwipeBetweenViewControllers after click on table cell . but i m unable to do it pls provide me solution .

Hey man, first, awesome job!
Second, I'm new to Xcode so please bear with me :-).

When I run you test it shows the app running in the middle of the screen with about a cm on the top and bottom (iphone6) of empty space - if I remember correctly there is a way to autosize - (self.view.frame.size.width/height) how would I implement that ?

I have 4 UIViewController organized by UITabBarController,
When I add RKSwipeBetweenViewControllers to the fourth tab controller, as soon as I click the 4th tab, the amount of controllers of UITabBarController become 3. The tab controller(RKSwipeBetweenViewControllers) is gone~

When I click the 4th one, it crashed~

when I use MFMailComposeViewController to send a mail,it was crash.

Is it possible if I send a pull request for swift demo project?

I'm hiding the segmentbuttons by putting in

pageController.navigationController.navigationBar.hidden = YES;

in the viewWillAppear in RKSwipeBetweenViewControllers.m. It mostly works fine, except when the app is first launched, there is a black bar where the status bar normally is. If I touch anywhere on the screen, the view slides up and everything works fine afterwards.
