您可以尝试关闭远程调试(Cmd-D ->停止远程JS调试)。这通常会加快速度。

使用模拟器时，在调试时不小心按下了慢动画。 运行模拟器->调试->取消选中慢速动画。

选择模拟器,

选择调试，取消选中慢动画。 快捷方式 Command + t

那是我的工作。

进入模拟器菜单 Device ->重启

然后一切都比你想象的快-_-

模拟器->重置内容和设置为我工作。当我远程调试我的反应本机代码时，这个问题似乎又出现了。也可以像nomad建议的那样使用AsyncStorage。

I don't have the rep yet to leave a comment, but I upvoted some answers here and wanted to say more. I had a problem with slow animations in the iOS Simulator, especially on rotation, and I found this post via Google. Indeed, somehow "Toggle Slow Animations" must have been on, because three shifts fixed it. At first, I didn't think this was a problem because there's no checkmark next to "Toggle Slow Animations." It turns out there's never a checkmark, or any indication from the menu whether it's on or off. So just try toggling it and see if the rotation/navigation is faster/slower.

所以，谢谢大家!
