My app uses UIAlertController for both ActionSheet and Alert. It works fine on iOS 8, but if I run the code from xCode 7 beta on my iOS 9 device, this is not working properly. For action sheet, I can only see 'Cancel' button there ( while there is few other buttons I added ). And for Alert, I only see the background become a little darker, without any alert window/UI at all

Later, I notice it happen because I'm forcing semantic to LTR in Arabic system
[[UIView appearance] setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight]; 

If I remove above code, UIAlertController works perfectly

Steps to Reproduce:
1. Put [[UIView appearance] setSemanticContentAttribute:UISemanticContentAttributeForceLeftToRight]; if the default language is RTL, 
or
put [[UIView appearance] setSemanticContentAttribute:UISemanticContentAttributeForceRightToLeft]; if the default language is LTR

2. Show UIAlertController
