2.3.4.184-pre1

"Height of ContextAction in ListView problem came back again. (iOS - XF2.3.4.184-pre1)

The problem was gone on XF2.3.3-SR1, and came back.

It ruins every UI for my ListView and fit to non-changable ContextAction height.

The height of my viewcell fit to ContextAction's button height, which means ContextAction's height does not follow ViewCell's height."

Confirmed good and bad results using the Forms Gallery ListView example. I'll upload the sample file.

Issue is not present in 2.3.3.180, and is present in 2.3.4.184-pre1 and the new pre2.

I faced this problem only on iPhone 5(iOS 10.2)

Thanks for your update.
I have a question.

What is the purpose of sample code for?
It's not a workaround, isn't it?
Comment 5 David Ortinau 2017-02-06 17:13:07 UTC
No, it's not a workout. It's a sample that shows can quickly be run to demonstrate the problem.

I'm seeing the same height problem in the iOS 7 simulator, 10.2.
Comment 6 Bright Lee 2017-02-06 17:28:47 UTC
Oh, I got it.

Hello,

I'm also experiencing this bug on the app I'm working on.
X.F. 2.3.4 is required for the android side (has resolved SO MANY problems) but this bug is hitting hard on the iOS side.

By far I've encountered this bug on all lists with custom viewcells on these devices 

iPhone4s (9.3) (real and simulator)
iPhone5  (10.2) (real and simulator)
iPhone5s (10.2) (real and simulator)
iPhoneSE (10.2) (simulator, don't have access to a real one)

In my case the viewcells don't have context actions, but they are still "clipped" to the default size.

will this bug be fixed before 2.3.4 final?
Comment 9 David Ortinau 2017-02-18 14:30:52 UTC
We looked at the issue this week and were able to reproduce on iPhone SE. iPhone 7 appeared to be fine. I spoke directly with engineering about it, and think we're on the right track to resolving it. More to come.

Is this bug not fixed yet?
It's not on the release-note list of 2.3.4-pre4.

I think this bug is serious. :)
I can't use a newest forms because of this.
