一颗熊的自由时光
一.文本自适应
self.bgview = [[UIView alloc]init];
UILable * label = [[UILabel alloc]init];
[self.bgview addSubview:label];
label.numberOfLines = 0;
label.text= @"此处是文字";
label.lineBreakMode = NSLineBreakByTruncatingTail;
//labelsize的高度的最小值，看到博客上有一些帖子设置的是最大值，用了一下，但是在我这里效果是不对的
CGSize LabelSize =CGSizeMake(UISCREENWIDTH-30,0);
CGSize expectSize = [label sizeThatFits:LabelSize];
label.frame=CGRectMake(15,0，expectSize.width, expectSize.height);
self.bgview.frame = CGRectMake(0, 0, UISCREENWIDTH,CGRectGetMaxY(label.frame));
二.加载html文字
NSString* htmlString =@"<html><body> Some html string \n <font size=\"13\" color=\"red\">This is some text!</font> </body></html>";
NSAttributedString *attrStr = [[NSAttributedString alloc] initWithData:[htmlString dataUsingEncoding:NSUnicodeStringEncoding] options:@{NSDocumentTypeDocumentAttribute:NSHTMLTextDocumentType} documentAttributes:nil error:nil];
suggestLabel.attributedText= attrStr;
三.label富文本
NSMutableAttributedString *attrStr = [[NSMutableAttributedString alloc]initWithString:self.suggest];
NSRangerange1 = [[attrStrstring]rangeOfString:@"基本满足中国营养协会的建议值。"];
[attrStraddAttribute:NSForegroundColorAttributeName value:[UIColor greenColor] range:range1];
suggestLabel.attributedText= attrStr;
