IOS 使用Text Kit编排图文

1 let textView = UITextView(frame：CGRect(x：20, y：
40, width：280, height：500))
2 textView.backgroundColor = UIColor.brown
3 self.view.addSubview(textView)
4
5 let textStorage = textView.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 image = UIImage(named：“Tea”)
15 let imageView = UIImageView(image：image)
16 let rect = CGRect(x：80, y：80, width：150, height：

17 imageView.frame = rect
18
19 imageView.layer.cornerRadius = 75
20 imageView.layer.masksToBounds = true
21 imageView.layer.borderWidth = 10
22 self.view.addSubview(imageView)
23 var frame = textView.convert(imageView.bounds,
from：imageView)
24 frame.origin.x -= textView.textContainerInset.left;
25 frame.origin.y -= textView.textContainerInset.top;
26
27 let path2 = UIBezierPath(ovalIn：frame)
28 textView.textContainer.exclusionPaths = [path2]
