自适应内容高度现在总结两种方法

方法一：其实就是先按着自己想要的效果给弄出来，然后根据宽度得到这个控件的cgsize

NSString * stringStr =@"我是内容我是内容我是内容我是内容我是内容我是内容..";

NSMutableAttributedString * attstr = [[NSMutableAttributedStringalloc] init];

//label图片文字混排

NSTextAttachment * textAttach=[[NSTextAttachmentalloc]init];

textAttach.image=[UIImageimageNamed:@"abstract"];

textAttach.bounds=CGRectMake(0,0, 42, 20);

NSAttributedString *strA = [NSAttributedStringattributedStringWithAttachment:textAttach];

[attstr appendAttributedString:strA];

[attstr appendAttributedString:[[NSAttributedStringalloc] initWithString:stringStr]];

//label行间距

NSMutableParagraphStyle *paragraphStyle = [[NSMutableParagraphStylealloc]init];

[paragraphStylesetLineSpacing:10];

[attstraddAttribute:NSParagraphStyleAttributeNamevalue:paragraphStyle range:NSMakeRange(0, [stringStrlength])];

UILabel * lbzy = [[UILabelalloc]init];

lbzy.attributedText=attstr;

lbzy.lineBreakMode=NSLineBreakByWordWrapping;

lbzy.numberOfLines=0;

lbzy.font=[UIFontsystemFontOfSize:13];

//调节高度

CGSize size = CGSizeMake(KWidth-20,MAXFLOAT);

CGSize labelSize = [lbzy sizeThatFits:size];

lbzy.frame =CGRectMake(10,10,KWidth-20,labelSize.height);//设置label的frame

方法二：这个是根据宽度得到内容的cgsize,然后赋值给label

//标题

NSString * stringStr = [@"我是标题"stringByTrimmingCharactersInSet:whitespace];

CGSize size=[stringStrsizeWithFontCompatible:[UIFontsystemFontOfSize:14]forWidth:(screenW-100)lineBreakMode:NSLineBreakByWordWrapping];

_newsTitle.frame=CGRectMake(91,0,screenW-100,size.height);

_newsTitle.lineBreakMode=NSLineBreakByWordWrapping;

_newsTitle.numberOfLines=0;

_newsTitle.text=stringStr;

NSDictionary *dictionaryAttributes =@{NSFontAttributeName:font,};

CGRect stringRect = [selfboundingRectWithSize:CGSizeMake(width,MAXFLOAT)

options:NSStringDrawingUsesLineFragmentOrigin

attributes:dictionaryAttributes

context:nil];
