带有"个人热点"蓝色条的"Unable to simultaneously satisfy constraints"

Question

当我运行应用程序并启用个人热点时，我只会收到以下警告，因此屏幕顶部有个人热点蓝条。有办法解决这个问题吗？

    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:0x145d307a0 'UIInputWindowController-top' V:|-(0)-[UIInputSetContainerView:0x145e77b70]   (Names: '|':UITextEffectsWindow:0x145d7e8d0 )>"

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.

我尝试按照调用中状态栏（Unable to Satisfy Constraints）中的建议，通过在AppDelegate中添加以下函数来修复它。不幸的是，它没有起到任何作用。

func application(application: UIApplication, willChangeStatusBarFrame newStatusBarFrame: CGRect) {
    for window in UIApplication.sharedApplication().windows {
        if window.dynamicType.self.description().containsString("UITextEffectsWindow") {
            window.removeConstraints(window.constraints)
        }
    }
}

该错误意味着您添加到个人热点酒吧的两个约束相互冲突，这意味着它们告诉酒吧去两个不同的地方。由于这是不可能的，您可以看到错误。为了解决这个问题，你必须查看你添加到酒吧的约束，看看其中两个是否会把酒吧放在不同的地方。Xcode实际上给了您这两个冲突的约束，在错误中显示了这两个约束。

要摆脱所有限制，请尝试以下操作：

func application(application: UIApplication, willChangeStatusBarFrame newStatusBarFrame: CGRect) {
    for window in UIApplication.sharedApplication().windows {
        window.removeConstraints(window.constraints)
    }
}
