IOS 实现图文混排

一、从本地获取txt文档

//从本地取出txt资源文件
        do {
            text = try NSString(contentsOfFile: NSBundle.mainBundle().URLForResource("haoshengyin", withExtension: "txt")!.path!, encoding: NSUTF8StringEncoding)
            text = (text as String).stringByAppendingString("\n")
        }catch {}
        //设置scrollView自动适应屏幕，不会有scrollView上方白一片的情况
        self.automaticallyAdjustsScrollViewInsets = false

二、对textView文档进行操作

// MARK --改变文字大小,颜色,行间距以及段落间距
        //创建可变属性字符串
        let attributedTextString = NSMutableAttributedString(string: text as String)
        //设置段落间距为可变型，设置为1.35倍间距
        let paragraphStyle = NSMutableParagraphStyle()
        paragraphStyle.lineHeightMultiple = 1.35*y1
        //设置可变字符串的属性，1.段落间距，2.范围是整个文本，3设置字体，4.设置颜色
        attributedTextString.setAttributes([NSKernAttributeName:1.8*y1,NSParagraphStyleAttributeName:paragraphStyle], range: NSMakeRange(0, text.length))
        attributedTextString.setAttributes([NSFontAttributeName:UIFont.boldSystemFontOfSize(18.0*y1),NSForegroundColorAttributeName:UIColor.blackColor()], range: NSMakeRange(0, 18))

        //设置textView的基本属性
        let textView1 = UITextView(frame:CGRectMake(15*x, 44+20*y1 , self.view.frame.size.width - 30*x, self.view.frame.size.height-44-20*y1))
        textView1.font = UIFont(name: "FZZhunYuan-M02S", size: 17.0*y1)
        textView1.attributedText = attributedTextString
        textView1.showsVerticalScrollIndicator = false
        textView1.editable = false
        textView1.scrollEnabled = true
        self.scrollView.addSubview(textView1)

三、设置图片为附件加入可变文本当中去

// MARK --设置图片为附件
        let string = NSMutableAttributedString(attributedString: textView1.attributedText)
        //创建属性字符
        let textAttachment = NSTextAttachment(data: nil, ofType: nil)
        //设置属性图片
        textAttachment.image = UIImage(named: "hsy.png")
        //设置属性布局位置
        textAttachment.bounds = CGRectMake(0, 0 , self.view.frame.size.width-30*x, 300*y1)
        //将属性字符设置为附件
        string.insertAttributedString(NSAttributedString(attachment: textAttachment), atIndex: self.text.length)
        //将属性文字加入到textView当中
        textView1.attributedText = string
