在Xcode的调试控制台输出中禁用自动布局约束错误消息

有没有一种方法可以（暂时）禁用自动布局错误/警告消息：

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. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) 
(
    "<NSLayoutConstraint:0x170098420 H:[UIView:0x15c62c100(2)]>",
    "<NSLayoutConstraint:0x170098600 UIView:0x15c6294f0.leading == UIView:0x15c628d40.leadingMargin - 8>",
    "<NSLayoutConstraint:0x170098650 H:[UIView:0x15c6294f0]-(0)-[UIView:0x15c62b750]>",
    "<NSLayoutConstraint:0x1700986a0 UIView:0x15c62b750.width == UIView:0x15c6294f0.width>",
    "<NSLayoutConstraint:0x1700986f0 UIView:0x15c628d40.trailingMargin == UIView:0x15c62b750.trailing - 8>",
    "<NSLayoutConstraint:0x170098880 H:[UIView:0x15c6294f0]-(0)-[UIView:0x15c62c100]>",
    "<NSLayoutConstraint:0x1700988d0 UIView:0x15c628d40.centerX == UIView:0x15c62c100.centerX + 1>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x170098420 H:[UIView:0x15c62c100(2)]>

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.

做了一些反编译，实际上有一种方法：

对于Swift 5

UserDefaults.standard.set(false, forKey: "_UIConstraintBasedLayoutLogUnsatisfiable")

物镜

[[NSUserDefaults standardUserDefaults] setValue:@(NO) forKey:@"_UIConstraintBasedLayoutLogUnsatisfiable"];

现在，您仅会收到“ _UIConstraintBasedLayoutLogUnsatisfiable为OFF”的通知。

强制性提醒所有阅读此内容的人：这应该是不得已的方法，有关调试和修复约束问题的提示，请参阅WWDC的“自动布局之谜”会议：第1部分和第2部分。

Swift 4.0和Swift 5.0解决方案：

//Hide Autolayout Warning
UserDefaults.standard.set(false, forKey: "_UIConstraintBasedLayoutLogUnsatisfiable")

Swift 3.0解决方案：

//Hide Autolayout Warning
UserDefaults.standard.setValue(false, forKey:"_UIConstraintBasedLayoutLogUnsatisfiable")

另一个选择是将选项卡下的菜单-_UIConstraintBasedLayoutLogUnsatisfiable NO（请注意破折号）暂时置于Arguments Passed On Launch菜单中Product -> Scheme -> Edit Scheme... -> Run -> Arguments（也可以通过按⇧+ ⌘+打开此菜单<），如下所示：

对于任何想知道如何使用AppKit / Cocoa进行macOS / osx的用户

UserDefaults.standard.set(false, forKey: "NSConstraintBasedLayoutLogUnsatisfiable")
UserDefaults.standard.set(false, forKey: "__NSConstraintBasedLayoutLogUnsatisfiable")

我试图使用lldb解决此问题，但找到了解决方案：

1. 在模块UIKit中为符号UIViewAlertForUnsatisfiableConstraints创建符号断点。
2. 作为断点操作，添加调试器命令“ thread return”
3. 添加第二个调试器命令：“ c”
4. 禁用“评估操作后自动继续”

如果您的应用遇到布局问题，则暂停执行。通过指令“线程返回”，在警告消息被打印到控制台之前，将强制返回打印出错误的UIViewAlertForUnsatisfiableConstraints函数。

使用“ c”命令继续执行应用程序（注意：“在评估操作后自动继续”在这种情况下不起作用）。

但是，使用这些自动操作，如果断点两次被击中，断点的行为可能会很奇怪导致您的应用崩溃的行。为了解决这个问题，您可以删除断点操作，并在调试器暂停程序执行时手动输入命令。
