IOS 使用Text Kit做排版

1 let firstTextView = UITextView(frame：CGRect(x：20,
y：40, width：135, height：200))
2 firstTextView.backgroundColor = UIColor.brown
3 firstTextView.isScrollEnabled = false;
4 self.view.addSubview(firstTextView)
5 let textStorage = firstTextView.textStorage
6 let path = Bundle.main.url(forResource：“word”,
withExtension：“txt”)
7 do {
8 let string = try String(contentsOf：path！)
9 textStorage.replaceCharacters(in：NSRange(location：
0,length：0), with：string)
10 }
11 catch{
12 print(“读取文件错误！”)
13 }
14 let secondRect = CGRect(x：165, y：40, width：135,
height：200)
15 let secondTextContainer = NSTextContainer()
16 let secondTextView = UITextView(frame：secondRect,
textContainer：secondTextContainer)
17 secondTextView.backgroundColor = UIColor.brown
18 secondTextView.isScrollEnabled = false;
19 self.view.addSubview(secondTextView)
20 let thirdRect = CGRect(x：20, y：250, width：280,
height：300)
21 let thirdTextContainer = NSTextContainer()
22 let thirdTextView = UITextView(frame：thirdRect,
textContainer：thirdTextContainer)
23 thirdTextView.backgroundColor = UIColor.purple
24 thirdTextView.isScrollEnabled = false;
25 self.view.addSubview(thirdTextView)
26 let layoutManager = NSLayoutManager()
27
layoutManager.addTextContainer(firstTextView.textContainer)
28 layoutManager.addTextContainer(secondTextContainer)
29 layoutManager.addTextContainer(thirdTextContainer)
30 textStorage.addLayoutManager(layoutManager)
