Description Jody Andrews 2014-02-22 05:50:13 UTC
Description of Problem:

PageViewController Transition Styles are not reflected correctly between iOS Designer and Interface Builder. They are the opposite of the (correct) transition style shown in interface builder

Steps to reproduce the problem:
1. Create a Page View Controller in iOS Designer and close.
2. In Interface Builder change transition style from Curl to Scroll
3. View Transition Style in iOS Designer

Actual Results:
Page Curl in iOS Designer shows as Scroll, and vice versa

Expected Results:
Transitional Styles should be correctly mapped

How often does this happen? 
100% recreatable

Additional Information:
Xamarin 4.3.2 
Xcode 5.0.2

Jeremie, when we select 'curl' we end up writing '1' to the xml. I think this is causing the issue they're seeing.

This should be backported as we are corrupting the xml.
Comment 2 Jérémie Laval 2014-03-04 12:32:30 UTC
Fixed the initial XML issue, but I have noticed a slew of problem on the server side which all seem to boil down to UIPageViewController thinking that the placeholder view we are using is a valid delegate or something.

That generates a lot of native error like:

-[MonoTouch.Design.PlaceholderView invalidatePageViewController]: unrecognized selector sent to instance 0x146c5ab0

I fixed the aspect of it now.
Comment 4 Shruti 2014-03-31 05:55:05 UTC
I have verified this by creating a small iOS application with page view controller. I followed the same steps mentioned in description and see following results.
1. Add PageViewController in MainStoryboard. By default property of Transition Style is' Page Curl'.
2. Close MainStoryboard page.
3. Right click on MainStoryboard  page > Open With > Xcode Interface Builder.
4. Change the of Transition Style into 'Scroll'.
5. Now Open MainStoryboard page in iOS designer, see the Transition Style it is appearing as 'Scroll'. 
6. Repeat step 2 and 3.
7.  Change the of Transition Style into 'Page Curl'.
8. Now Open MainStoryboard page in iOS designer, see the Transition Style it is appearing as 'Page Curl'.

Comment 5 Jody Andrews 2014-04-01 06:33:37 UTC
Shruti, your environment build paste suggests you're testing with an earlier version of Xamarin Studio and Xamarin.iOS than the one this bug was reported with. Am I just reading into that wrong and the fix was actually added to the 4.2.x builds as well. 4.3.4 is the latest public alpha build and still exhibits the same issue.
Comment 6 Alan McGovern 2014-04-01 06:35:00 UTC
The fix has not shipped yet. It will be in the next alpha, whenever that is released.
