Xcode 6 GM building error

WaterFallViewCell init fails while using this in a master detail app

I am using this within a master-detail app and calling WaterFallViewController when an item is selected in the master view (table). App is not able to load the WaterfallView and failing at required init(coder aDecoder: NSCoder) calling the fatal error. Debug trace is:

Swift._assertionFailed (Swift.StaticString, Swift.String, Swift.StaticString, Swift.UInt) -> () ()

Any thoughts?

PoptoRootViewContoller shows empty screen

After you pushed another viewcontroller to your detail view controller , if you want to poptoRootViewController i see empty white screen.

Ho to fix that ?

Swift 3

it'd be cool to have a swift 3 version, if you have any interest to create a branch i would like to help with that.

Static Images

Hi
Please make it for images downloading from some source.

滑动到最底部的时候，push 和 pop 后 会出现不完美的显示

这里有个不完美的展示，如下图。
我发现是由于 NTTansition 这句前后转换坐标的时候，出现不一致的情况，pop 前后取出来的值竟然不一致，具体相差 64 pixel 刚好；如果没有滑到最后，或者多半不会出现这种不一致的情况。
很想知道问题在哪里，还希望花点时间来看下，谢谢😄
let leftUpperPoint = gridView!.convertPoint(CGPointZero, toView: toViewController.view)

push 之前

pop 之后

Using Your Code in Appcelerator

Hi there,
I was wondering whether you could provide direction as how to use your transition in Appcelerator. Any guidance would be greatly appreciated.

Oh NO! Xcode 6 beta x>3

Fix build error after XCode 6 GM. I don't wanna do something pointless again.

Swipe from left gesture

As well as the custom shrink effect, Pinterest lets you swipe from left to go back. Is it possible to include this in PinterestSwift? Alternatively, could the custom transition be animated as the user swipes from the left?

您好！有什么好办法转为OC的代码呢？

@demon1105
您好！如果看完逻辑对应写OC代码是可以完成的对吧？或者如题有什么好的办法呢？

License?

First, thanks for building this library!

Second, I'm a bit confused about the licensing. The README states that it's MIT licensed, but the code states that it's "All Rights Reserved."

Would it be possible to get the inline code comments updated to reflect the README?

I'd be happy to send a Pull Request that makes the change--if you're OK with the change.

Thanks!

please update for swift 2.0

Hi, can you update this project for swift 2.0 now have some warnings.

Is this supporting XCode 9 and Swift 4

一上来代码就编译不过去

如题 ：）

Compiler issue in Xcode6.1

can not build

NTHorizontalPageViewController cellForItemAt always entered with indexPath: (0, 0)

Hello, I started having this problem after updating to XCode 12.0.1 and ios14. Before the update everything worked fine with ios 13.

I will explain how I set up the project because I'm not an expert at XCode and I might be doing something wrong:

1. I cloned this repo, then dragged all of the classes into an existing project I was working on.

2. From the cloned project's storyboard, I copy pasted your navigation controller and the NTWaterfallViewController into my own project's storyboard as shown below. (I also tried building it from from scratch on the storyboard but got the same result). I set the classes to NTNavigationController and NTWaterfallViewController

Now when I run the project I see the Waterfall Collection View as expected. But no matter what image I click on, I ALWAYS get the image cell at indexpath (0,0)

The cellForItemAt() function inside NTHorizontalPageViewController is always entered with indexpath: (0,0). I also checked the setToIndexPath() method but it's entered with the correct indexpath(0,3).

When I recreate this on the cloned project it works fine(even on ios 14). But when I try to incorporate it into a new project by following the 2 steps I mentioned above, I get this bug. So maybe I'm doing something wrong during installation? Please point me in the right direction. Thank you!

Edit: I tried with iPhone 8(ios 14) and it worked. The problem is specific to iPhone X and iPhone 11.

The problem probably has to do with:
pageView.scrollToItem(at: indexPath as IndexPath, at:.centeredHorizontally, animated: false)
inside NTTransition. The scroll statement just doesn't work anymore with ios14 and xcode12

Using dispatch_async to load image will cause the transition take the wrong snapshot of picture

This is probably not related to the existing code, but just to mention

When swipe the horizontal view back to the first item and then going back to the waterfall view, it could not find the correct indexPath
