When I run pod install, it gives me the error :

Cocoa Pods - [!] Unable to find a specification for RGPageViewController

cannot find the following 2 optional func on RGPageViewControllerDelegate,and these two func was introduced in the README.md

optional func colorForTabIndicator() -> UIColor

optional func tintColorForTabBar() -> UIColor?

I have RGPageViewController in NavigationController. It is working as expected. However, the bottom border line is missing from Navigation Bar when user opens a view controller from the RGPageViewController. I am not sure if this is related with RGPageViewController.

It seems that barTop no fit for me ,I ignore by adding a debug flag

let yeshen_debug = false
"
var barTop: CGFloat = tabbarTop
// remove hairline image in navigation bar if attached to top
if let navController = navigationController where !navController.navigationBar.hidden {
barTop = tabbarTop + 44
navController.navigationBar.hideHairline()
}
"
if(yeshen_debug){ barTop = 0 }

Hello,
I have a problem that sometimes, the viewControllerForPageAtIndex function is being called twice when a new page is loaded. This prevents me from calling javascript on the current web view.

Is there a way I can center the tabs to have equal widths. My tabs are only 2 displayed at the top

i want to set current index to tab 2 for the first time launch the app.

How to remove bounces effect?

As suggested in "Install" section of Readme, I just copy RGPageViewController.swift file in my project.

Unfortunately there are a lot of compile errors, first at line 142:

        self.view.addConstraints(constraints)

"Cannot invoke 'addContraints' with an argument list of type '(NSMutableArray!)'"

Other errors are all where you use "as" with the error:

" 'Any object' is not convertible to .... :did you mean to use 'as!' to force downcast?"

Not sure if anyone else has had this issue but I've just tested one of my applications with xCode 9 beta and iOS 11 beta and all of a sudden the tabbar will not slide and I am not able to select any of the other tabs.

This is a awesome lib and thank you for that , Can you tell how to add navigationItem.rightBarButtonItem in UIViewController i have try adding rightButton in UIViewController but it will not showed in my UI, but when i add bar button on RGPageViewController it showed perfectly can you tell me how to add button from my UIViewContorller ? because it need to access the content of my UIViewController when button clicked

I didn't see any sliding UIView demo app inside your Xcode project.

Please advice. Thank you.

Does anyone have this working well? It seems to not be consistent, instead of switching views at bottom of list it switches sometimes before. Sometimes it does not switch at all. I believe this is because the two gestures (ScrollView down/up swipe) and PageView are conflicting.

Hi,

above mentioned problem presents itself when adding:
func pageViewController(_ pageViewController: RGPageViewController, willChangePageTo index: Int, fromIndex from: Int) { print("Will change page") }

I inserted it into your example and it wasn't called either.

How to change Y position of Tab bar , any delegate method for that?

hi, thx for this implementation and as title, how to reload data ?

App is crashing on iOS 11 and below but working perfectly fine on iOS 12 using xcode 11.

Collectionview Cell is being returned nil in iOS 11 on dequeCell withIdentifier.

Hi. How to add bottom border to tabView? (https://cloud.githubusercontent.com/assets/7591019/10017028/08d2c8bc-614d-11e5-9d8e-dda731d874ce.png)

First of all, thanks for sharing your pager with us...Unfortunately I am having problem when using your library.

When I applied this example with UITabBarController, there are some issue.

1. View Between Pager Tab and TabBarItem can't scroll to down completely.

2. This issue may be related to view controller constraints inside pager and tabbar. Can't tell for sure yet. But, please take a look

If you don't mind, updating example project with UITabBarController and TopBar support is appreciated. So, I can check if I am doing anything wrong.

Best Regards

This is a awesome lib and thank you for that , Can you tell how to add navigationItem.rightBarButtonItem in UIViewController i have try adding rightButton in UIViewController but it will not showed in my UI, but when i add bar button on RGPageViewController it showed perfectly can you tell me how to add button from my UIViewContorller ? because it need to access the content of my UIViewController when button clicked

This was just a request for your example project update because it only show using it with Single View Controller inside Pager.

So, how do we use it for different UIViewController?

Any Help?

Hello,
How to present an alert view from my content view controller ? When I perform alertView.show() I got this error in the console:

Attempt to present <UIAlertController: 0x7fb321cdba20> on <_UIAlertShimPresentingViewController: 0x7fb321c68390> whose view is not in the window hierarchy!

Thanks for your help

if i use your code like this :
let cv = MainViewController()
window!.rootViewController = UINavigationController(rootViewController: cv)

view look some bugs.

https://puu.sh/ubORP/9ec2e07cec.png

From the look of this image, Tab Items are on left side with same tab spacing...it will be better if all 6 tabs are show properly like UITabBarController rotation on tabitems.

Just an advice my friend....

Thanks for creating such beautiful library.

Hello,
I used your awesome project in my app but the tab bar hide a part of my table view. How to fix that ?

Thanks

Hi I'm using RGPageViewController with multiple tabs and its working good
But when I try to use it with only 1 tab its freezing in the below line

  tabScrollView.layoutIfNeeded()

Do you know how can I fix that?

1. I add UITableiViewController to Example's storyboard

2. code change below
   ` func pageViewController(_ pageViewController: RGPageViewController, viewControllerForPageAt index: Int) -> UIViewController? {
   if (movies.count == 0) || (index >= movies.count) {
   return nil
   }

   // Create a new view controller and pass suitable data.
   let dataViewController = storyboard!.instantiateViewController(withIdentifier: "tableView") as! UITableViewController

   //dataViewController.movieData = movies[index]

   return dataViewController
   }`

3. tab bar cover top part of UITableViewController
   

First of all,its the first library which can use dynamic tab and dynamic content for each tab without need to initiate view controllers manually like other library do.You just use one controller and change data according to each index.Yeah pretty smart one.Thanks for your hard work...

But,I really do have some problem.If you have some time,can you fix it?

When rotating the device,it appear like that..

@eRGoon
Hi,

I want to show next viewcontroller's some part in the current viewcontroller so that user can know that he can swipe to go through different viewcontrollers.
