我有一个UITextView,并且我要用粗体显示某些要用NSString stringWithFormat转换的单词。

我环顾了Stack Overflow,并尝试按照发布的内容进行操作,但我想我不太理解。

这是我一直在玩的东西:

    NSRange boldedRange = NSMakeRange(0, 4);
    NSString *boldFontName = [[UIFont fontWithName:@"Helvetica-Bold" size:100]fontName];


    NSMutableAttributedString *attrString = [[NSMutableAttributedString alloc] initWithString:self.name];

    [attrString beginEditing];
    [attrString addAttribute:NSFontAttributeName
                       value:boldFontName
                       range:boldedRange];
    [attrString endEditing];

    self.resultsTextView.attributedText = attrString;


    self.resultsTextView.text = [NSString stringWithFormat:@"One day, %@ was taking a walk and saw a %@ boy.  He was %@ a %@.", attrString, self.adjective, self.adverb, self.noun];

最佳答案

如果需要,还可以通过以下方式设置字典:将字典整体设置为属性

NSString *strTextView = @"This is some demo Text to set BOLD";

NSRange rangeBold = [strTextView rangeOfString:@"BOLD"];

UIFont *fontText = [UIFont boldSystemFontOfSize:10];
NSDictionary *dictBoldText = [NSDictionary dictionaryWithObjectsAndKeys:fontText, NSFontAttributeName, nil];

NSMutableAttributedString *mutAttrTextViewString = [[NSMutableAttributedString alloc] initWithString:strTextView];
[mutAttrTextViewString setAttributes:dictBoldText range:rangeBold];

[textViewTermsPolicy setAttributedText:mutAttrTextViewString];
