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];

  returnattrString;

}

NSString*constmsg = @"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];
