<div class =“post-text”itemprop =“text”> <P> 您需要设置约束 <code> activate state = true </code> 。你可以做到这一点， </p> <pre> <code> NSLayoutConstraint.activate([ //Move your existing code HERE with comma separated ]) </code> </pre> <P> 如有任何问题，您可以检查以下功能： </p> <pre> <code> func setConstraints() { NSLayoutConstraint.activate([ switchTheme.bottomAnchor.constraint(equalTo: self.view.safeAreaLayoutGuide.bottomAnchor), // bottomAnchor to set bottom target. switchTheme.leftAnchor.constraint(equalTo: self.view.leftAnchor), // leftAnchor to set X left switchTheme.rightAnchor.constraint(equalTo: self.view.rightAnchor), // rightAnchor to set X right switchTheme.heightAnchor.constraint(equalToConstant: 40.0) //heightAnchor to set appropriate height. ]) } </code> </pre> </DIV>

<div class =“post-text”itemprop =“text”> <P> 您的约束必须激活： </p> <pre> <code> switchTheme.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true </code> </pre> </DIV>

<div class =“post-text”itemprop =“text”> <P> 你需要像这样简单地激活这些约束： </p> <pre> <code> switchTheme.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true switchTheme.leftAnchor.constraint(equalTo: view.leftAnchor).isActive = true switchTheme.rightAnchor.constraint(equalTo: view.rightAnchor).isActive = true switchTheme.heightAnchor.constraint(equalToConstant: 40.0).isActive = true </code> </pre> </DIV>
