【问题描述】：

我想像这样创建一个UILablel。

我想将年份字体设置为 HElvaticaNeu-medium 并将 2015 设置为 HelvaticaNeu。我需要这两个字符串出现在 2 行中，就像在这张图片中一样。

我怎么能做到这一点。我这样设置了两个单独的NSMutableAttributedString。

UIFont *helMedium = [UIFont fontWithName:@"HelveticaNeue-Medium" size:12.0];
NSDictionary *mediumDict = [NSDictionary dictionaryWithObject: helMedium forKey:NSFontAttributeName];
NSMutableAttributedString *mAttrString = [[NSMutableAttributedString alloc] initWithString:@"Year :" attributes: mediumDict];

UIFont *helNormal = [UIFont fontWithName:@"HelveticaNeue" size:12.0];
NSDictionary *normalDict = [NSDictionary dictionaryWithObject: helNormal forKey:NSFontAttributeName];
NSMutableAttributedString *nAttrString = [[NSMutableAttributedString alloc] initWithString:@"2016" attributes: normalDict];

现在我应该如何将这 2 个字符串设置为两行？有人有想法吗？

【问题讨论】：

"\n" 字符是您正在寻找的。将其添加到 helMedium stings end 或 helNormal string's start

【解决方案1】：

您需要将第二个字符串附加到第一个字符串

使用此代码。

UIFont *helMedium = [UIFont fontWithName:@"HelveticaNeue-Medium" size:12.0];
NSDictionary *mediumDict = [NSDictionary dictionaryWithObject: helMedium forKey:NSFontAttributeName];
NSMutableAttributedString *mAttrString = [[NSMutableAttributedString alloc] initWithString:@"Year :" attributes: mediumDict];

UIFont *helNormal = [UIFont fontWithName:@"HelveticaNeue" size:12.0];
NSDictionary *normalDict = [NSDictionary dictionaryWithObject: helNormal forKey:NSFontAttributeName];
NSMutableAttributedString *nAttrString = [[NSMutableAttributedString alloc] initWithString:@"\n2016" attributes: normalDict];

[mAttrString appendAttributedString:nAttrString];

label.attributedText = mAttrString;

【解决方案2】：

NSMutableAttributedString *nAttrString = [[NSMutableAttributedString alloc] initWithString:@"\n2016" attributes: normalDict];

NSMutableAttributedString  *attString = [[NSMutableAttributedString alloc] init];
[attString appendAttributedString: mAttrString];
[attString appendAttributedString: nAttrString];

// label.attributedText = attString

【解决方案3】：

  UIFont *helMedium = [UIFont fontWithName:@"HelveticaNeue-Medium" size:12.0];
  NSDictionary *mediumDict = [NSDictionary dictionaryWithObject: helMedium forKey:NSFontAttributeName];
  NSMutableAttributedString *mAttrString = [[NSMutableAttributedString alloc] initWithString:@"Year :" attributes: mediumDict];

  UIFont *helNormal = [UIFont fontWithName:@"HelveticaNeue" size:12.0];
  NSDictionary *normalDict = [NSDictionary dictionaryWithObject: helNormal forKey:NSFontAttributeName];
  NSMutableAttributedString *nAttrString = [[NSMutableAttributedString alloc] initWithString:@"\n2016" attributes: normalDict];

  [mAttrString appendAttributedString:nAttrString];
  _yearLabel.attributedText = mAttrString;
  [_yearLabel setNumberOfLines:2];

如果您希望在 UILabel 中的文本周围有更多空间，请为其指定宽度和高度约束。
