ios - "Unable to simultaneously satisfy constraints"个人热点蓝条

Question

当我运行我的应用程序并启用个人热点时，我仅收到以下警告，因此个人热点蓝条出现在屏幕顶部。有办法解决这个问题吗？

2016-05-19 09:07:55.589 RemindersPro[591:121237] 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:0x145d7ff30 V:|-(20)-[UIInputSetContainerView:0x145e77b70]   (Names: '|':UITextEffectsWindow:0x145d7e8d0 )>",
    "<NSLayoutConstraint:0x145d307a0 'UIInputWindowController-top' V:|-(0)-[UIInputSetContainerView:0x145e77b70]   (Names: '|':UITextEffectsWindow:0x145d7e8d0 )>"
)

Will attempt to recover by breaking constraint 
<NSLayoutConstraint:0x145d7ff30 V:|-(20)-[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 In Call Status Bar (Unable to Satisfy Constraints) 中的建议修复它通过将以下函数添加到我的 AppDelegate 中。不幸的是，它没有帮助。

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栏的两个约束相互冲突，这意味着它们告诉该栏去两个不同的地方。由于这是不可能的，您会看到该错误。为了修复它，您必须查看您添加到栏中的约束，看看其中两个约束是否会将栏放在不同的位置。 Xcode 实际上为您提供了这两个冲突的约束，并在错误中显示了它们。

要摆脱所有限制，试试这个:

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