UITextKit and exclusionPaths: undependable indent when editing - xcode

Question

I have a problem with UITextKit using exclusionPaths: when I place an image inside a TextView, that I’m editing, first everything looks fine:
But when the „Done“-Button is tapped, it will look like this, the ident is wrong:
This is the class to store the informations for the image
class ImageClass {
var image: UIImage!
var imageView: UIImageView
var imageName: String!
var active:Bool
var exclusivePath: UIBezierPath!
init(image: UIImage!, imageName: String!) {
self.image = image
imageView = UIImageView(image: image!)
self.imageName = imageName
self.active = false
self.exclusivePath = nil
}
}
The user chooses the image in a UICollectionView that fires a delegate, when the image was selected. (imageViewObjects is an array, where I can put objects of ImageClass, so I can use mutiple images)
// MARK: - SelectImageDelegate
func selectedImage(name:String) {
let image = UIImage(named: name)
let imageViewObject = ImageClass(image: image, imageName: name)
self.imageViewObjects.append(imageViewObject)
imageViewObject.imageView.frame = CGRectMake(4, 7, width!, height!)
// define the exlusionPaths
let bezierPath = self.exclusionPathForImageView(imageViewObject.imageView)
imageViewObject.exclusivePath = bezierPath
self.updateExclusionPaths()
self.textView.addSubview(imageViewObject.imageView)
}
// set UIBezierPath for the UIImageView
func exclusionPathForImageView(imageView: UIImageView) -> UIBezierPath {
let bezierPath = UIBezierPath(rect:
CGRectMake(imageView.frame.origin.x, imageView.frame.origin.y,
imageView.frame.width, imageView.frame.height))
return bezierPath
}
func updateExclusionPaths() {
textView.textContainer.exclusionPaths = []
for imageViewObject in self.imageViewObjects {
textView.textContainer.exclusionPaths.append(imageViewObject.exclusivePath)
}
}
The context of bezierPath is ok.
When „Done“ is tapped, I stop the editing
let doneBarButton = UIBarButtonItem(title: "Done", style: .Done, target: view, action: Selector("endEditing:"))
In textViewDidEndEditing() now I do nothing.
I also tried it with a UIButton for the image. Similar result.
Any tip for a solution? plz help me!!!!

found a workaround:
func textViewShouldEndEditing(textView: UITextView) -> Bool {
textView.editable = false
}
and I had to add to set textView.editable = true, i.e. in viewDidLoad()
let tapGesture = UITapGestureRecognizer(target: self, action: "resetEditable")
tapGesture.numberOfTapsRequired = 1
self.textView.addGestureRecognizer(tapGesture)
func resetEditable() {
textView.editable = true
textView.becomeFirstResponder()
}
