我需要使用 UILabel 显示文本(不能使用 UIWebView ),它有时包含希伯来语和英语。使用 UILabel 的默认设置,句子会变得混乱并且没有意义。我没能找到一种方法让 UILabel 显示文本 rtl。

有谁知道要这样做,或者实现这个的代码?

I need to display a text using a UILabel ( can't use UIWebView ), and it sometimes contains both Hebrew and English. using UILabel's default settings the sentence gets mixed up and doesn't make sense. I have failed to found a way to make UILabel display text rtl.

Does anybody know anyway to do that, or a code that implements this?

看看这个SO,它包含一些信息这个主题可能会对您有所帮助。
通过将代码 \u200F 添加到要显示的字符串中,这似乎对某些人有用。

NSString *RTFstr = "1. בבוקר"; //This could be any right-to-left string
NSString *directionalString = [@"\u200F" stringByAppendingString:[note text]];
[someUITextView setString:directionalString];

Have a look at this SO, it contains some info on this subject that might help you out.
It seems to work for some by adding the code \u200F to the strings to be displayed.

NSString *RTFstr = "1. בבוקר"; //This could be any right-to-left string
NSString *directionalString = [@"\u200F" stringByAppendingString:[note text]];
[someUITextView setString:directionalString];

这会起作用

-(void)fnForWritingDirection:(UILabel*)label textFor:(NSString *)stringForText{

    NSMutableAttributedString* attrStr = [[NSMutableAttributedString alloc] initWithString: [stringForText stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

    [paragraphStyle setBaseWritingDirection:NSWritingDirectionRightToLeft];

    [attrStr addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [attrStr length])];

    label.attributedText=attrStr;

}

This will work

-(void)fnForWritingDirection:(UILabel*)label textFor:(NSString *)stringForText{

    NSMutableAttributedString* attrStr = [[NSMutableAttributedString alloc] initWithString: [stringForText stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];

    NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];

    [paragraphStyle setBaseWritingDirection:NSWritingDirectionRightToLeft];

    [attrStr addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, [attrStr length])];

    label.attributedText=attrStr;

}
