iOS中UILabel text两边对齐的实现代码

废话不多说了，直接给大家贴代码了，具体代码如下所示：

									-(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];
