我对暗恋没有任何想法。我在 Fabric 上看到了暗恋日志。并且没有重复。

1.查看所有使用CAGradientLayer的代码 2.多次尝试从后台进入前台

self.airHubbleView?.dismissAirHubble(isHaveNext: false, completion: { [weak self] (isComplate) in
            guard let `self` = self else { return }
            self.airHubbleView?.removeFromSuperview()
            self.airHubbleView = nil
            NotificationCenter.default.removeObserver(self)
        })

airHubbleView 是一个自定义视图。自定义视图使用 CAGradientLayer 创建颜色渐变。堆栈跟踪：

我想得到一些想法。
