Custom Class

[DanielSmith1239]

Hello,
I am trying to present a custom view controller in the pager controller, but I keep getting the following error printed:
2015-07-28 00:37:36.056 YidKit[529:59574] Attempt to add this NSLayoutConstraint to an engine in which it already exists. This can cause engine corruption. Break on void _NSLayoutConstraintRedundantAdd() to debug. This will be logged only once. This may break in the future.

Thank you for the help.

Hi,
It may be same case with #48 ?
Presenting only one custom view controller hasn't supported yet, but it will be fixed soon.

[DanielSmith1239]

I added an additional view controller to test that out, and that was the problem. However, now I am experiencing another one. The selected tab moves to the side of the screen, not to the center. Also, How do I make the menu's appearance not opaque?
I am extremely close to completing my app, and this is the final component I need to complete before submitting it, so I would appreciate it if you could help me ASAP. I understand that you are likely extremely busy, and I don't want to pressure you or anything. I really appreciate the help, and I will (of course) give you credit in my app's "About" section.

Could you give me all the options you set for PagingMenuOptions? Because it's much easier to find out the reason of the unexpected behaviour. Also it would be great if I could see its screenshots.

[DanielSmith1239]

Here is my code for the options: let options = PagingMenuOptions()
options.menuHeight = 44
options.menuDisplayMode = PagingMenuOptions.MenuDisplayMode.FlexibleItemWidth(centerItem: true, scrollingMode: PagingMenuOptions.MenuScrollingMode.ScrollEnabledAndBouces)
options.textColor = UIColor.blackColor()
options.backgroundColor = UIColor(netHex: 0xFCFCFC)
options.menuItemMode = PagingMenuOptions.MenuItemMode.Underline(height: 2, color: UIColor(netHex:0x0066FF))

    let pagingMenuController = self.childViewControllers.first as! PagingMenuController
    pagingMenuController.delegate = self
    pagingMenuController.setup(viewControllers: viewControllers, options: options)

Also, I just realized that the selected tab centers (as it should) while running in the iOS simulator, but it doesn't center when on a physical device (see image below).

Thanks for helpful info. Also could you tell me what version of PagingMenuController you are using?

[DanielSmith1239]

I am using the version for swift 2.

[kitasuke]

I'm digging into more detail with your options and try to tell you what's wrong ASAP. Please wait a bit more.

FYI, since Xcode 7 is still beta, any project written in Swift 2.0 can not be submitted at this moment if I'm correct.

Thank you, I apreciate all of the help.

The selected tab moves to the side of the screen, not to the center. Also, How do I make the menu's appearance not opaque?

I set same options as yours and it works fine on my device. I'll look into more detail and let you know if there is something wrong.
I didn't make it opaque. How do you think it's opaque?

Please try the latest version and reopen this issue if there is still something wrong.
