The Picker on iOS fires off the SelectedIndexChanged event as the user scrolls through the items in the control, not after an item is actually selected.
### Steps to Reproduce
1. Run the attached iOS project
2. Open the Picker and scroll through the items
### Expected Results
Selecting an item from the Picker will update the Label beneath the Picker.
### Actual Results
The Label is updated as the items in the Picker are scrolled through.
### Testing Info
I was able to reproduce this on Forms 2.0.1 and 2.1-pre3. However, this does not occur on the default Forms 1.3.5 from the new project template. So indicates that this is a regression introduced since then.
Just to clarify, the issue doesn't happen when the user is actually scrolling, but when they highlight the item in the Picker and don't select "Done".
So if one iterates through the items one by one, the label in the sample project changes each time a new item is highlighted.
Should be fixed in 2.3.4-pre2
I have checked this issue with Xamarin.Forms 188.8.131.52-pre1 and this issue is not reproducible with latest forms version I am getting same behaviour with Android and iOS. Hence marked this issue as Verified Fixed.
If you still facing same issue please feel free to reopen this issue.
I have the same issue as described on iOS 11 simulator using Xamarin.Forms 184.108.40.2062
I'm using an iOS Device (iPad with 10.3.3) with Xamarin.Forms 220.127.116.117 and I'm also experiencing the same issue. In which XF version is this fixed? Also this
doesn't seem to exist. Here (https://forums.xamarin.com/discussion/comment/180760/#Comment_180760) someone tried a workaround.
Sorry guys, this was a false alarm. With
this works and the issue has been indeed fixed. You also need this
so that he recognizes that correctly.
I think this (https://xamarin.uservoice.com/forums/258559-xamarin-forms-suggestions/suggestions/6507788-synchronize-picker-behavior-across-platforms) can be closed.
