Assuming you have a crappy model which contains properties with a locale identifier as suffix (like "title_de", "title_en" etc), `localizedProperty(NSString*, id)` returns a specific translation of that property. This Gist provides a global function and is ready to use :-)

Helpers.h

NSString* localizedProperty(NSString* propertyName, id fromObject);

Helpers.m

#include "Helpers.h"

NSString* localizedProperty(NSString *propertyName, id fromObject) {
    NSString *locale = [[NSLocale preferredLanguages] objectAtIndex:0];
    NSString *value = @"";
    
    NSMutableString *localizedPropertyName = [NSMutableString stringWithString:propertyName];
    [localizedPropertyName appendString:@"_"];
    [localizedPropertyName appendString:locale];
    
    SEL getter = NSSelectorFromString(localizedPropertyName);
    if([object respondsToSelector:getter]) {
        value = [object valueForKey:localizedPropertyName];
    }
    
    return value;
}
