我的应用程序有时会崩溃，但我无法重现这一点，而且我也不知道崩溃的原因。在我在崩溃文件（ips）中找到的链接下面： http://we.tl/SRb84J750O
在日志中我找到了

Dec 6 15:56:18 DreamIt SpringBoard[197] <Warning>: Unable to simultaneously satisfy constraints.
Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.
(
"<NSLayoutConstraint:0x15f039b90 V:[UIView:0x15f029410]-(-1)-| (Names: '|':UITableViewCellContentView:0x15f7ab4c0 )>",
"<NSLayoutConstraint:0x15f6dbae0 V:[UIView:0x15e4abc40]-(0)-| (Names: '|':UIView:0x15f029410 )>",
"<NSLayoutConstraint:0x15e3cae20 UIView:0x15e4abc40.top == UITableViewCellContentView:0x15f7ab4c0.top>",
"<NSLayoutConstraint:0x15f7387c0 V:[UIView:0x15e4abc40(119)]>",
"<NSLayoutConstraint:0x15e327a20 'UIView-Encapsulated-Layout-Height' V:[UITableViewCellContentView:0x15f7ab4c0(117.5)]>"
)
Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x15f7387c0 V:[UIView:0x15e4abc40(119)]>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.
