本文介绍了一个Objective-C方法，用于将指定名称的图片插入到NSAttributedString中，并允许调整图片的垂直偏移量。通过创建并配置NSTextAttachment对象，该方法能够灵活地控制图片的位置和大小。

-(NSAttributedString *)imagesWithimgName:(NSString* )imgName offsetY:(CGFloat)offsetY
{
    NSTextAttachment * textAttachment = [[NSTextAttachment alloc]init];
    UIImage * smileImage = [ UIImage imageNamed:imgName];
    textAttachment.image = smileImage ;
    textAttachment.bounds = CGRectMake(0, offsetY, smileImage.size.width, smileImage.size.height);
    return [NSAttributedString attributedStringWithAttachment:textAttachment];
}

-(void)appendImgStr:(NSString* )imgName offsetY:(CGFloat)offsetY
{
    [self appendAttributedString:[self imagesWithimgName:imgName offsetY:offsetY]];
}
