源码是

public func animateTransition(using transitionContext: UIViewControllerContextTransitioning) {
        guard let browser = photoBrowser else {
            transitionContext.completeTransition(false)
            return
        }
        if isForShow {
            browser.maskView.alpha = 0
            browser.browserView.alpha = 0
            if let toView = transitionContext.view(forKey: .to) {
                transitionContext.containerView.addSubview(toView)
            }
        } else {
            if isNavigationAnimation,
                let fromView = transitionContext.view(forKey: .from),
                let toView = transitionContext.view(forKey: .to) {
                transitionContext.containerView.insertSubview(toView, belowSubview: fromView)
            }
        }
        UIView.animate(withDuration: transitionDuration(using: transitionContext), animations: {
            browser.maskView.alpha = self.isForShow ? 1.0 : 0
            browser.browserView.alpha = self.isForShow ? 1.0 : 0
        }) { _ in
            transitionContext.completeTransition(!transitionContext.transitionWasCancelled)
        }
    }

因为是偶发，没办法定位，想问下您这边有什么想法和建议？

JiongXing commented 4 years ago

用的是哪个版本的库？

JiongXing commented 4 years ago

如果不知道的话，用文本编辑器打开podfile.lock搜JXPhotoBrowser搜搜看。我好找对应版本代码看

JiongXing commented 4 years ago

大概是个怎样操作下的崩溃？能知道不？

Jaylin0920 commented 4 years ago

没有使用pod，是拿的源码，2天前刚用的，是Download下来最新的代码

Jaylin0920 commented 4 years ago

在第一次打开图片浏览器的时候，产生的崩溃。崩溃日志就是我上面发的那些，可以看到的东西很少，所以我这边也没什么想法

JiongXing commented 4 years ago

你是如何使用这个库的，代码可以发下我看看吗？

Jaylin0920 commented 4 years ago

代码业务比较多，不太好拆开，我看了下，很难复现这个Bug，最后当做是系统bug暂不处理了

Jaylin0920 commented 4 years ago

还是很感谢楼主百忙中的回复，感谢🌹

JiongXing commented 4 years ago

感谢反馈，如果我找到原因修复了就通知你
