ios - The UIlabel AttributedString first line indentation -

1. label text first line need indent，i use nsmutableparagraphstyle setfirstlineheadindent.

2. but when label 1 line, attributedstring intercept omitted behind few characters,why?

   nsmutableparagraphstyle *style = [nsmutableparagraphstyle new]; [style setfirstlineheadindent:11]; [[nsattributedstring alloc] initwithstring:@"abcdefg" attributes:dic];
