UITextView startInteractionWithLinkAtPoint仅崩溃iOS 11 [英] UITextView startInteractionWithLinkAtPoint crash iOS 11 only

问题描述

因此，当用户与URL链接进行交互时，我在UItextview中遇到崩溃。所有崩溃报告仅限iOS版本11。
这看起来像是iOS 9中众所周知的错误，但是没有单个报告iOS版本低于11，而且在报告中我发现有趣的行：

So I experience crash in UItextview while user interacts with URL link there. All crash reports have iOS version 11 only. This looks like well-known bug in iOS 9, but there is no single report iOS versions lower than 11, and also in report I found interesting line:

UITextGestureClusterLinkInteract smallDelayRecognizer:

随iOS 11附带（ http://developer.limneos.net/?ios= 11.0&安培;框架= UIKit.framework&安培;首标= UITextGestureClusterLinkInteract.h ）。
无论如何，现在我修复它

which came with iOS 11 (http://developer.limneos.net/?ios=11.0&framework=UIKit.framework&header=UITextGestureClusterLinkInteract.h). Anyway, for now I fixed it with

@available(iOS 10.0, *)
func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange, interaction: UITextItemInteraction) -> Bool {
    UIApplication.shared.openURL(URL)
    return false
}

这不是很酷，因为你丢失了动作表菜单。
我的假设是它是由3D触摸引起的（比如先前版本中的长按），但如果我检测到3D触摸（75％，甚至是最大力的50％）并禁用此特定手势的链接交互 - 问题仍然出现。
有没有人对这个特殊问题有一些经验和更优雅的解决方法？

which is not so cool, because you lose action sheet menu. My assumption was that it is caused by 3D touch (like by long press in previous versions), but if I detect 3D touch (75%, or even 50% of maximum force) and disable link interaction for this specific gesture - issue still appears. Does anybody has some experience with this particular issue and more elegance way of solving it?

推荐答案

导致崩溃iOS 11.0和11.1上的 UIDragInteraction / UITextDragAssistant 。它在iOS 11.2上修复。对UITextView进行子类化并禁用拖放手势可以防止任何iOS版本崩溃：

A crash is caused by a UIDragInteraction/UITextDragAssistant on iOS 11.0 and 11.1. It is fixed on iOS 11.2. Subclassing your UITextView and disabling drag and drop gestures will prevent the crash for any iOS version:

class NoDragDropTextView: UITextView {

    override func addGestureRecognizer(_ gestureRecognizer: UIGestureRecognizer) {

        // required to prevent drag and drop gestures
        // also prevents a crash on iOS 11.0-11.1
        gestureRecognizer.isEnabled = false

        super.addGestureRecognizer(gestureRecognizer)
    }
}
