ios - UITextView 文本在文本中间的每个单词之间留出小间隙

Question

团队，

我让 UITextView 添加了文本内容，使用字体系列 avinar roma，我注意到每个单词之间的间隙很小，不一致。如何避免每个单词在 textview 文本中出现小间隙。

    descriptionTextView = [[UITextView alloc] initWithFrame:CGRectMake(20, titlelabel.frame.origin.y + titlelabel.frame.size.height + 5, view.frame.size.width - 40, view.frame.size.height - 150)];
    descriptionTextView.backgroundColor = [UIColor clearColor];
    descriptionTextView.textColor = MH_PANTONE_444;
    descriptionTextView.textAlignment = NSTextAlignmentCenter;
    descriptionTextView.font = [UIFont fontWithName:MH_FONT_AVENIRROMAN size:MH_SCREEN_HEIGHT/48];
    descriptionTextView.text = [descriptionArray objectAtIndex:index];
    descriptionTextView.editable = NO;
    descriptionTextView.scrollEnabled = NO;
    descriptionTextView.selectable = YES;
    descriptionTextView.dataDetectorTypes = UIDataDetectorTypeAll;

请附上图片大学医学中心，与剩余文本不相同。

设置hyphenationFactor应该可以解决您的问题。但你必须使用 NSAttributedString 而不是纯文本:

UIFont *font = [UIFont fontWithName: MH_FONT_AVENIRROMAN size: MH_SCREEN_HEIGHT/48];
NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStyle alloc] init];
paragraphStyle.hyphenationFactor = 1.0;

NSDictionary *attributes = @{ NSFontAttributeName:font,
                              NSForegroundColorAttributeName: MH_PANTONE_444;
                              NSParagraphStyleAttributeName: paragraphStyle };

NSMutableAttributedString *attributedText = [[NSMutableAttributedString alloc] initWithString: [descriptionArray objectAtIndex:index]
                                                                                   attributes: attributes];

descriptionTextView.attributedText = attributedText;

您可能需要调整hyphenationFactor，直到获得所需的结果。 (0.0-1.0)
