ios - 如何为第一段设置 NSMutableParagraphStyle firstLineHeadIndent

Question

我只想firstLineHeadIndent为多段设置第一段UILabel，我该怎么做

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

Answer 1

尝试使用更小的范围：

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