iPhone:UITextView环绕UIImage？

Question

如何让UITextView将其文本包装在UIImage中,就像在这张图片中一样？

图像尺寸不一定是先前已知的.

Answer 1

IOS 7及以上:

UIBezierPath * imgRect = [UIBezierPath bezierPathWithRect:CGRectMake(0, 0, 100, 100)];
self.textView.textContainer.exclusionPaths = @[imgRect];

Swift(感谢Bart van Kuik):

let exclusionPath = UIBezierPath(rect: CGRectMake(0, 0, 100, 100))
self.textView.textContainer.exclusionPaths = [exclusionPath]
