register (lr) is very likely to contain the return address of frame #0's calling function, and have inserted it into the crashing thread's backtrace as frame #1 to aid in analysis. This determination was made by applying a heuristic to determine whether the crashing function was likely to have created a new stack frame at the time of the crash.

Answer 1

我无法为您提供准确的诊断，但也许这些观察结果可能有助于缩小可能性范围。

1）崩溃不在你的代码中（至少不是直接），因为堆栈跟踪只包含系统/ UIKit调用。

2）在编写字符串时发生错误，该字符串似乎是报告布局约束问题的错误（警报）消息。

3）尝试显示警报之前的调用表明布局约束正在尝试调整坐标舍入为整数值。

4）正在处理的布局是在准备UITableView单元格。但它可能不会调用您的代码（即不会出现自定义的UITableViewCell）。所以这将是tableview中的静态或标准单元格。

5）布局处理的模式似乎表明＆＃34;比例＆＃34;涉及约束，并且大小和比率产生的值超过整数的大小。准备错误消息时出错的事实让我相信这可能与无效的数值有关。请注意，可能还有其他原因导致字符串失败，但调用的上下文与大数字一致。

6）布局过程由值观察者触发，该观察者不会调用您的代码（或者至少似乎没有）。问题的触发器（用户操作）可能是应该/应该自动处理的UI更改事件（例如设备方向更改）。由于这发生在iPhone上，您可以排除分屏问题（您只能在iPad上获得）。其他可能的事件取决于您的应用程序的作用。

通过这种方式，您可以缩小具有静态单元格UITableview的视图的可能性。这些单元格必须包含一些使用比例约束的子视图（例如纵横比，相对高度/宽度）。请注意，布局约束函数的名称表明这可能是tableView单元格和tableview之间自动设置的相关内部约束。事件是这样的，在某些时候，至少会涉及到你自己的一个约束。

如果你的应用程序没有大量的表格视图，你可以把你的调查重点放在＆＃34;自动＆＃34;对可以在您拥有的UITableviews上执行的用户操作的反应。鉴于这种情况发生在iPhone上，您还需要通过展开segues或dismiss（）来检查从模态视图返回的转换。 iPhone和iPod经常从呈现的VC中释放一些UI元素，这在某些情况下可能会导致不必要的行为。

希望这有帮助。
