objective c - How to set Arabic text to right and English text to left on same label

Question

I learned how to make English and Arabic project from previous question I asked.

Same Project at github

Now what I did is added a label in this project and wrote "Welcome".

The problem is the layout. When I have English text it is at left side (obviously), but when the Arabic text comes, it should start from right to left. But it is aligned to left only.

Any idea how to deal with such case?

Below are the screenshots...

Below is what I did...

Added fonts in projects folder (english.ttf & arabic.ttf) as shown here.

In Localizable.strings added "myFont"="ACS Zomorrod"; (Arabic) & "myFont"="Armalite Rifle"; (English)

and then had those font in condition

NSString *myFont = localize(@"myFont");
NSString *cpFont = @"Armalite Rifle";
if ([myFont isEqualToString:cpFont]) {
    self.myLabel.textAlignment = NSTextAlignmentLeft; // this is for English
} else {
    self.myLabel.textAlignment = NSTextAlignmentRight; // this is for Arabic
}

Edit 1

Also you could have "myLang"="arabic"; & "myLang"="english"; in Localizable.strings and then have code as

NSString *myLang = localize(@"myFont");
NSString *myActualLang = @"english";
if ([myLang isEqualToString:myActualLang]) {
    self.myLabel.textAlignment = NSTextAlignmentLeft; // this is for English
} else {
    self.myLabel.textAlignment = NSTextAlignmentRight; // this is for Arabic
}

I will prefer the second option instead of first as tomorrow if I change the font, I would have to do changes at line NSString *cpFont = @"Armalite Rifle"; in all files.
