Question

我对暗恋没有任何想法。我在Fabric上看到了喜欢的日志。而且没有重复。

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

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：

我想知道一些想法。
