Copying and pasting image into a textbook in simulator

问题

I'm manually setting the copied content in the pasteboard

@IBAction func onOkPressed( button: UIButton ) {
    var testImage = getImageWithColor(UIColor.redColor(), size: CGSize(width: 100, height: 100));
    UIPasteboard.generalPasteboard().image = testImage
}

func getImageWithColor(color: UIColor, size: CGSize) -> UIImage {
    UIGraphicsBeginImageContextWithOptions(size, false, 0)
    color.setFill()
    UIRectFill(CGRectMake(0, 0, 100, 100))
    var image = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    return image
}

But when I paste the image into a textbox in simulator it doest not paste the image. I've tried this with a local png image as well instead of manually creating the image. When I paste onto the textbook in my custom keyboard app, it pastes the text from my mac clipboard instead of the image. However, if I programmatically do UIPasteboard.generalPasteboard().string = "TeST", the expect string gets pasted. Anyone know what could be wrong? Thanks.
