Wrapping Text in a UITextView Around a UIImage WITHOUT CoreText

Is there a way to wrap text from a UITextView around a UIImage without using CoreText?

I have been playing around with attributed strings without much luck, and CoreText just seems extremely complicated so I would rather stay out of it.

Solution

  • This seems to do the trick:

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

    Swift,

    textView.textContainer.exclusionPaths = [UIBezierPath(...)]

    or just

    textView.textContainer.exclusionPaths = [UIBezierPath(rect: the image frame)]

    Note that the path is expressed in the frame of the text view.

    Hence for example ...

    yourTextView.textContainer.exclusionPaths =
 [UIBezierPath(rect:
  CGRect(
   origin: CGPoint(x: yourTextView.frame.width - 50, y: 0),
   size: CGSize(width: 50, height: 50))
)]

    that would leave out a rectangle, 50x50, at the top right of your text view.

    Note too that in many cases you have to set the exclusion area in layout - since both your text view and the image may have been reshaped or shaped for the first time.

    override func layoutSubviews() {
    super.layoutSubviews()
    ...
    yourTextView.textContainer.exclusionPaths = ...
}
