AutoLayout + RTL + UILabel text alignment

Question

I\'m finally getting round to wrestling with Auto Layout and can\'t seem to figure out how to get right-to-left (RTL) support to work the way I\'d expect/want...

For me those solutions didn't help, and I ended up doing something pretty ugly but it's the only one that did the trick for me. I added it as an NSString category:

NSString+Extras.h:

#import 

@interface NSString (Extras)
- (NSTextAlignment)naturalTextAligment;
@end

NSString+Extras.m:

#import "NSString+Extras.h"

@implementation NSString (Extras)

- (NSTextAlignment)naturalTextAligment {
    NSArray *tagschemes = [NSArray arrayWithObjects:NSLinguisticTagSchemeLanguage, nil];
    NSLinguisticTagger *tagger = [[NSLinguisticTagger alloc] initWithTagSchemes:tagschemes options:0];
    [tagger setString:self];
    NSString *language = [tagger tagAtIndex:0 scheme:NSLinguisticTagSchemeLanguage tokenRange:NULL sentenceRange:NULL];
    if ([language rangeOfString:@"he"].location != NSNotFound || [language rangeOfString:@"ar"].location != NSNotFound) {
        return NSTextAlignmentRight;
    } else {
        return NSTextAlignmentLeft;
    }
}
@end

To detect the language I used this SO answer.
