Strange line when "flipping cats" on Retina in Simulator

[ivira]

Hi,

I've tried your app in Simulator (Version 5.1 (272.12)) and Device iPhone (Retina). And when I play with "Tickle Image Down"/"Tickle Image Down" I'm seeing strange vertical line at the "center of cat".
Maybe just a simulator issue...

Yeah, seen that one as well, I hope it's a Simulator bug, we keep this issue open if any one detects it on a real device.

It happened on the real devices. Anyone knows how to fix this issue , or the author already fixed it yet?

I got a solution to remove this line ,

Open the SBTickerView , method : - (void)_initializeTick:(SBTickerViewTickDirection)direction
and found the code below, comment those two lines.

CATransform3D perspective = CATransform3DIdentity;

// float zDistanse = 400;
// perspective.m34 = 1. / -zDistanse;
[_flipLayer setSublayerTransform:perspective];

I have not had a look at this code for many years, but commenting out those lines will result in no perspective on the transform.

Hi,
Yes, you are right, the strange line did disappeared when I commented
those tow line codes. And as you said, no perspective effect .

And finally , I figured it out what happened .

The thing is,

You know UIView (SBExtras) this category, this is the key point , the
method [** image] never be called.
Because the sample you provided showed us like this:

[imageTickerView setFrontView:[[UIImageView alloc]

initWithImage:[UIImage imageNamed:@"front.jpeg"]]];
[imageTickerView setBackView:[[UIImageView alloc]
initWithImage:[UIImage imageNamed:@"back.jpeg"]]];

You got it right , we input the UIImageView, not UIView , so , method " -
(UIImage*)image" in UIView (SBExtras) will never be called.

The simple way to solve this issue is just to add a UIImageView (SBExtras)
and also applied the same category method "- (UIImage*)image".

Thanks for your replying.
