Animation doesn't work in iPhone 5S (iPhone 64bits)

[FuriouZz]

In the Simulator, animation has a strange behavior. In the device, no animation works.

So, umm, does it?

[FuriouZz]

The problem comes from AHEasing. I needed to define AH_EASING_USE_DBL_PRECIS in my Pods-environment.h file. In 64bits, the app don't use float but double. When you use CGFloat the change works fine but AHEasing use its proper float named AHFloat.

[zrxq]

I'll reopen the issue just so I remember to do something about it.

I suggest a pull request to AHEasing author.

https://github.com/warrenm/AHEasing/pull/8

Just define AH_EASING_USE_DBL_PRECIS if it's __LP64__

Switching on AH_EASING_USE_DBL_PRECIS didn't work when I attempted... all that seemed to do was stop easing altogether.

However, switching the typedef in this library from

typedef CGFloat (*ViewEasingFunctionPointerType)(CGFloat);

to

typedef float (*ViewEasingFunctionPointerType)(float);

Seems to solve it, at least for me. Thoughts?

[zrxq]

Hard to tell without looking at the code/project.

@jkosoy's suggestion solved it for me too, thanks!

[refactornator]

@jkosoy's suggestion worked for me too.

[cerupcat]

@jkosoy's suggestion worked. Would love to get this committed.

[jkosoy]

For what it's worth I don't believe that my solution was appropriate for the library - it was just a hotfix for the problem. I haven't had time to build a correct solution myself -- should I find the time I'll submit a pull request.

Yeah , one day it worked , the next day it isn't .

[ghost]

So - the problem I am facing is that suddenly changing

typedef CGFloat (_ViewEasingFunctionPointerType)(CGFloat); to typedef float (_ViewEasingFunctionPointerType)(float);

works for some days , then it doesn't after some 10 - 20 compiles , then you change it back to

typedef CGFloat (*ViewEasingFunctionPointerType)(CGFloat);

and it miraculously will start working once again for the next 10 - 20 compiles. Right now i changed CGFloat to AHFloat thinking at this might just work every time.

Haven't faced any problem since i changed as per the comment above.

Specifically created a new repo which changes the implementation inside but works almost in the same way, couldn't add bouncy & elastic animations but if you are using other easings you should try it. https://github.com/thegreatloser/UIView-Easing

I'm facing a strange problem with iPhone 5S, when animating a frame, changing only it's origin.y value, on a iPhone 4S everything works fine, but on iPhone 5S the origin values (x and y) gets changed to a value lower than it should be, then when the animation ends, it gets back to desired value.

[DenninDalke]

it seems to be related to iOS8, I tested on iPhone4S with iOS8 and the same problem happened.

@DenninDalke - try the repo above

I tried and it worked, but I'd like to have elastic easing working too.
