如何为第一段设置NSMutableParagraphStyle firstLineHeadIndent

Question

我想将firstLineHeadIndent设置为多段UILabel的第一段，我如何做？

NSMutableParagraphStyle *paragraphStype = [[NSMutableParagraphStyle alloc] init];
paragraphStype.firstLineHeadIndent = 10.0f;
[att addAttribute:NSParagraphStyleAttributeName value:paragraphStype range:NSMakeRange(0, att.length)];

Answer 1

试着使用更小的范围：

NSMutableParagraphStyle *paragraphStype = [[NSMutableParagraphStyle alloc] init];
paragraphStype.firstLineHeadIndent = 10.0f;
[att addAttribute:NSParagraphStyleAttributeName value:paragraphStype range:NSMakeRange(0, 10)];
