iOS中UILabel text两边对齐的实现代码

 -(NSAttributedString *)setTextString:(NSString *)text {  NSMutableAttributedString *mAbStr = [[NSMutableAttributedString alloc] initWithString:text]; NSMutableParagraphStyle *npgStyle = [[NSMutableParagraphStyle alloc] init]; npgStyle.alignment = NSTextAlignmentJustified; npgStyle.paragraphSpacing = 11.0; npgStyle.paragraphSpacingBefore = 10.0; npgStyle.firstLineHeadIndent = 0.0; npgStyle.headIndent = 0.0; NSDictionary *dic = @{ NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName      :[UIFont systemFontOfSize:15.0], NSParagraphStyleAttributeName :npgStyle, NSUnderlineStyleAttributeName :[NSNumber numberWithInteger:NSUnderlineStyleNone] }; [mAbStr setAttributes:dic range:NSMakeRange(0, mAbStr.length)]; NSAttributedString *attrString = [mAbStr copy]; return attrString; } NSString* const msg = @"6日，“幼儿园老师让带一条鱼”的微博突然间就火了！占领朋友圈！征服全国网友.图片甚至遭网友恶搞：水煮鱼、生鱼片都出来了。1月7日，记者在茫茫人海之中，历经千辛万苦终于在浙江慈溪找到了这位被网友吐槽的“粗心”家长！来听听他的解释吧"; self.lbView.attributedText = [self setTextString:msg];
