这次研究的目标是NSTextView 控件的文本处理图片处理问题
这是一个初步演示，在这里我们建立一个类来处理文本的写入问题。你建立一个Cocoa工程，然后在View里拖入一个NSTextView对象，并在
ViewController类中添加 textView 变量。然后在viewDidLoad() 函数中添加代码。令人你需要找一个girl.jpg文件，也拖入工程。
用到的代码全部列在后面，就不解释了。
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
let attachmentCell = NSTextAttachmentCell(imageCell: NSImage(named: "girl.jpg"))
let attachment = NSTextAttachment()
attachment.attachmentCell = attachmentCell
let attributedStr = NSAttributedString(attachment: attachment)
self.textView.textStorage?.insert(attributedStr,at: 0)
let designer = TextAttributedDesigner("Designer Example")

designer.newline()
let para = NSMutableParagraphStyle()
para.alignment = .center
designer.append("this is paragraph text,the text is so length over than normal text line.",attrType: AttributeItemType.paragraphStyle(para))
designer.newline()
let para1 = NSMutableParagraphStyle()
para1.firstLineHeadindent = 20
designer.append("this is left indent text,the text is so length than normal text line.this is left indent text,the text is so length over than normal text line.this is backgroundColor indent text,attrType: AttributeItemType.paragraphStyle(para1))
designer.newline()

designer.newline()
designer.newline()
// 如果想有外框效果。
designer.append("OUTLINE",attrTypes: [.strokeColor(NSColor.blue),.strokeWidth(1) ])
designer.newline()
self.textView.insertText( designer.attributedString,replacementRange: NSMakeRange(0,0))
