iOS，动画视图'；s约束导致错误“；“无法同时满足约束”；

我正在尝试设置容器视图约束之一的动画。在IB中，视图约束良好，没有错误或警告。在viewDidLoad中调用这些方法时，要更改视图y坐标，请执行以下操作：

 self.queueContainerYConst.constant += 550;
    [self.view layoutIfNeeded];

我收到“无法满足约束…”的消息。在运行应用程序时，我的动画和UI看起来很好，所有内容似乎都受到了适当的约束。这是我在控制台中得到的全部信息

    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)

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.

可能下面列表中至少有一个约束是您不想要的。试着这样做：（1）看看每个约束，试着找出你不期望的约束；（2） 找到添加了不需要的约束的代码，然后修复它。（注意：如果您看到不理解的NSAutoresizingMaskLayoutConstraints，请参阅UIView属性TranslatesAutoResizingMaskToConstraints的文档）

将尝试通过打破约束进行恢复
在UIViewAlertForUnsatifiableConstraints处创建一个符号断点，以便在调试器中捕获该断点。
中列出的UIView上UIConstraintBasedLayoutDebugging类别中的方法也可能会有所帮助。

看来容器视图中的所有内容都放错了位置，为什么？。我是否不正确地设置/更改视图的动画

您的视图被过度约束。您的superview顶部的约束为614，底部的约束为0，但该视图的高度为568，因此这些数字不相加。如果出于您的目的，最好只使用其中一个垂直约束和一个固定的视图高度（如果您调整它以适应不同的屏幕大小，“固定”高度可以相对于superview的高度）

是的，这是正确的，谢谢。如何使视图的高度相对于超级视图？我可以在IB中这样做吗？@Andy是的，你可以在IB中这样做。选择视图及其超视图，然后从pin菜单中选择“等高”。然后编辑该约束，将乘数值从1更改为所需的分数。
