UILabel插入图片简单操作
1.需求
image.png
2.解决方案
UILabel有attributedString属性. NSAttributedString有NSTextAttachment属性可以支持在文本中插入附件 ** 例如图片 ** .从而达到在文本中插入图片的效果
3.代码
//初始化
NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] init];
//空格间隙
NSAttributedString *spaceString = [[NSAttributedString alloc] initWithString:@" "];
//图片
NSTextAttachment *attachment = [[NSTextAttachment alloc] init];
attachment.image = image;
attachment.bounds = CGRectMake(0, -3, 19, 19);
NSAttributedString *imageAttachment = [NSAttributedString attributedStringWithAttachment:attachment];
//图片
[attributedString appendAttributedString:imageAttachment];
//空格间隙
[attributedString appendAttributedString:spaceString];
//文字
NSMutableAttributedString *textString = [[NSMutableAttributedString alloc] initWithString:text];
NSRange textRange = NSMakeRange(0, text.length);
//行间距
NSMutableParagraphStyle *style = [[NSMutableParagraphStyle alloc] init];
style.lineBreakMode = NSLineBreakByTruncatingTail;
style.lineSpacing = 5;
[textString addAttribute:NSParagraphStyleAttributeName value:style range:textRange];
//文字颜色
[textString addAttribute:NSForegroundColorAttributeName value:textColor range:textRange];
//字体
[textString addAttribute:NSFontAttributeName value:textFont range:textRange];
4.为什么需要空格间隙
因为插入图片之后,文字会紧贴着图片.NSTextAttachment设置的bounds是图片的大小,没有设置间隙的属性,所以就用个空格去代替间隙
