什么是UICalloutBarButton，为什么它会让我的应用程序崩溃？ [英] What is UICalloutBarButton, and why does it make my app crash?
问题描述
我正在浏览我的iPhone应用程序的一些报告崩溃报告，我对以下内容感到难过。
I'm going through some of the reported crash reports for my iPhone app, and I'm stumped by the following.
它很可能在某处崩溃我的代码 - 它可能是一个事件处理程序在某处调用错误的选择器。问题是我不知道这个代码是什么 - 我不知道UICalloutBarButton或UICalloutBar是什么。
It's very possible it crashes somewhere in my code - it may be an event handler calling the wrong selector somewhere. The problem is I have no idea WHERE this code is - I don't know what a UICalloutBarButton or UICalloutBar is.
另外，不用说，我无法重现这是我的结论，否则很容易弄清楚它发生在哪里。
Also, needless to say, I can't reproduce this on my end, otherwise it'd be easy to figure out where it's happening.

推荐答案
UICalloutBar 是一个UIKit私有API 。
UICalloutBar is a UIKit private API.
我认为这是文本选择中出现的上下文菜单...（复制/粘贴......）
I think this is the contextual menu that appears on text selection... (Copy/Paste...)
无论如何，这次崩溃真的很喜欢来自内部API。
Anyway, this crash really likes coming from internal APIs.
所以我猜它是：
- 一个苹果错误（检查iOS版本与崩溃事件发生）
- 或某人使用带有脏内容的越狱设备/调整内部API的混乱
我担心你找到修复的可能性非常低。我希望我错了！ ：）
I'm afraid that the chances you find a fix for this are very low. I hope I'm wrong! :)
