ios - Flip layout on iPhone for RTL languages -

here issue :

i've localized application in arabic. (it's different regular localization, have different targets, 1 each language).

on simulator, view flipped, auto-layout , leading / trailing part of constraints, can't seem same result on device. autolayout + rtl + uilabel text alignment shows example of flipped view on simulator.

i've found indication supported in auto-layout guide : « the attributes leading , trailing same left , right left-to-right languages such english, in right-to-left environment such hebrew or arabic, leading , trailing same right , left ». lets me think supposed flip view, on simulator.

i use -applelanguages (ar_sa) in scheme on simulator, flips view, fail find proper setting in device same thing. setting language , region format arabic doesn't seem much. on iphone 4s, ios 7.0.4

tldr: setting should change on actual iphone device in « arabic environment » , have flipped view, or missing flips in simulator not on device ?

ended adding following : 

int main(int argc, char *argv[]) {     @autoreleasepool { #if target == target_ar         nsuserdefaults * defaults = [nsuserdefaults standarduserdefaults];         [defaults setobject:[nsarray arraywithobject:@"ar-sa"] forkey:@"applelanguages"];         [defaults synchronize]; #endif         return uiapplicationmain(argc, argv, nsstringfromclass([snfidledetectorapplication class]), nsstringfromclass([snfappdelegate class]));     } } 

though find kind of ugly.

edit : may interesting note when set arabic, device shows @"ar" applelanguages first value, , not @"ar-sa". guess flipping view doesn't work @"ar" locale, although i'm unsure whether that's bug, or if arabic countries write ltr, making sense not systematically flip view.
