Hi Andrea, I'm having problems implementing AMWaveTransition on a Swift project - iOS 8 - Xcode 6.

The crash message is: -[__NSArrayI setTransform:]: unrecognized selector sent to instance 0x7fba99c5d930

the crash occurs in this method on the line: [view setTransform:CGAffineTransformMakeTranslation(delta, 0)];

Any help with this error and implementing in Swift would be greatly appreciated.

Thanks Rob

- (void)hideView:(UIView *)view withDelay:(NSTimeInterval)delay andDelta:(float)delta
{
    void (^animation)() = ^{
        [view setTransform:CGAffineTransformMakeTranslation(delta, 0)];
        [view setAlpha:0];
    };
    void (^completion)(BOOL) = ^(BOOL finished){
        [view setTransform:CGAffineTransformIdentity];
    };
    if (self.transitionType == AMWaveTransitionTypeSubtle) {
        [UIView animateWithDuration:self.duration delay:delay options:UIViewAnimationOptionCurveEaseIn animations:animation completion:completion];
    } else if (self.transitionType == AMWaveTransitionTypeNervous) {
        [UIView animateWithDuration:self.duration delay:delay usingSpringWithDamping:0.75 initialSpringVelocity:1 options:UIViewAnimationOptionCurveEaseIn animations:animation completion:completion];
    } else if (self.transitionType == AMWaveTransitionTypeBounce){
        [UIView animateWithDuration:self.duration delay:delay options:UIViewAnimationOptionCurveEaseInOut animations:animation completion:completion];
    }
}

please refer to this gist, https://gist.github.com/i0sdev/475262e6de902fd9bca8

I found this when after updating to 0.5.3.

The issue is:

i.e., there two view controllers, the first one (table view) is using AMWaveTransition, tap any cells then push to the second view controller, a normal view controller not table view as a simple sample.

set background color for the second one, like gray or any.

run the sample, show the first one view controller correctly, tap and then show the second one, but found the background that's supposed to be gray color disappears instead.

I downgraded it to 0.5.2, it shows as expected, the gray background on the second view controller.

Why?

Your anim is really cool, I love its and would like to integrate into my project. Everything is ok, but while I trying to swipe quickly on table view cell, it crash. Here is the log and screenshot

Hope you can take a look and fix Thank

Sometimes navigating back through nav stack will flash present the 'toVC' view before animating it into display, which produces a nasty jumpiness.

A resolution seems to triggering a layout before performing the seemingly necessary animation to load visible cells.

    // Move the destination in place
    toVC.view.frame = [transitionContext finalFrameForViewController:toVC];
    // And kick it aside
    toVC.view.transform = CGAffineTransformMakeTranslation(delta, 0);

    [transitionContext containerView].backgroundColor = fromVC.view.backgroundColor;

    [[transitionContext containerView] layoutIfNeeded];

    // First step is required to trigger the load of the visible cells.
    [UIView animateWithDuration:0 delay:0 options:UIViewAnimationOptionCurveEaseIn animations:^{} completion:^(BOOL finished) {

In my app, I have a couple of View Controllers each with a tableview as well as a HeaderView. the transition in the cells work well but the header views don't animate well. For example, both header views are visible during the transition before the initial header view animates out. This is not good.

The reason I use a View Controller with subviews (tableview and header view) instead of a tableview controller is for ad banner support. The ads are difficult to control with the tableview controller.

Any ideas on how I should handle the header view animations - I'd really like to use this library in my upcoming app. Thank you.

I noticed on my pop animations, the cells of the fromVC were animating properly, however the superview was animating backwards (to the left), when it was supposed to be animating to the right.

I finally narrowed down that on line 414, I was able to fix the issue by changing:

[fromVC.view setTransform:CGAffineTransformMakeTranslation(delta, 0)];

to:

[fromVC.view setTransform:CGAffineTransformMakeTranslation(0, 0)];

I'm not sure if that is a bug, or if it was intended to be that way, but with the change I made, the animation looks a lot cleaner.

Can you let me know if I made a proper change, or if I potentially screwed something else up in doing this change?

Thanks for the great work!

The interactive pop gesture positions the visible cells wrong when using the translucent navigation bar. In my project the cells are being positioned where the navigation bar should be when the gesture is pending and when it completes they move to their correct positions, but in your Demo project they are also positioned at the wrong coordinates.

Is there any quick fix for this?

Hey,

I added some changes in my fork of your wonderful project

https://github.com/voznesenskym/AMWaveTransition/compare/andreamazz:master...master

I was hoping to do a bit of cleanup by removing some of the if-else ambiguity, and changed some defines to statics.

I also gave the user the ability to access the transition style directly, which I thought could perhaps help this grow into something more expansive. If you want it to just stay a wave thats cool too.

If you are interested let me know, and ill add my changes.

If the pushed or popped view controller is a UITableViewController (or has a tableView property), implementation of the protocol is not needed anymore. Especially if (section) header and footer views are involved, the implementation would get quite lengthy.

Refactored the code (DRY).

Your sample is great! I leverage it in my app, which looks good! Thank you!

Tried non-transparent backgrounds of two UITableView, when transition, it looks weird. The background is moving slower than table view when back to the first level table view from the second level. Do you found that? Or, is anything wrong or I missed?

I have a view controller with two UITableViews, the VC is currently acting as the delegate/dataSource for both UITableViews. Is there any way to conditionally return the correct NSArray of visibleCells?

I am aware the correct way to do it would be to have separate delegate/dataSource classes for the second UITableView but I want to know if it is possible without doing this? Thanks!

Ciao Andrea!

I was thinking about trying implement this on a swift project. Checking around , i wasn't able to get a swift version, or get if there s one. Is it possible integrate this into a swift project?

PS Effetto pulito e molto bello

It would be cool to be able to delay the pop or have an animation curve, kind of like this: https://dribbble.com/shots/1968347-GIF-for-the-ECHO-Feed-Dribbble-800x600?list=users&offset=1

-moved from Define to const -add viewControllers inset -add alpha changing for interactive transition -fixed bug with 0 index in interactive transition -add fullscreen pan interactive transition -interactive transition working without visible cells as plain transition -fixed bug with wrong transition when visible cells count = 0 -refactor handlePan method

There is one bug when pop fourth vc to third with interactive transition - table view header 'y' gets wrong, but after transition complete header gets into right position. In my projects transition works properly, and i don't know how to fix this bug in demo. Take a look.

Sorry for my english.
