用自己的宽度约束按钮

Question

确实为constrain而奋斗buttons。

我想要做的就是将我的2 buttons设置为height为35，并且他们的width应该是他们所需要的。现在看起来像这样（左右按钮）：

这是我设置它们的方式：

let communityButton: UIButton = {
    let v = UIButton()
    v.setImage(UIImage(systemName: "person.3.fill"), for: .normal)
    v.tintColor = UIColor.darkCustom
    v.imageView?.contentMode = .scaleAspectFill
    v.contentHorizontalAlignment = .fill
    v.contentVerticalAlignment = .fill
    v.translatesAutoresizingMaskIntoConstraints = false
    v.addTarget(self, action: #selector(communityButtonTapped), for: .touchUpInside)
    return v
}()

let profileButton: UIButton = {
    let v = UIButton()
    v.setImage(UIImage(systemName: "person.fill"), for: .normal)
    v.tintColor = UIColor.darkCustom
    v.imageView?.contentMode = .scaleAspectFill
    v.contentHorizontalAlignment = .fill
    v.contentVerticalAlignment = .fill
    v.translatesAutoresizingMaskIntoConstraints = false
    v.addTarget(self, action: #selector(profileButtonTapped), for: .touchUpInside)
    return v
}()

约束：

//contrain communityButton
communityButton.centerYAnchor.constraint(equalTo: bottomBar.centerYAnchor),
communityButton.centerXAnchor.constraint(equalTo: bottomBar.centerXAnchor, constant: -view.frame.width/3.5),
communityButton.heightAnchor.constraint(equalToConstant: 35),

// constrain profileButton
profileButton.centerYAnchor.constraint(equalTo: bottomBar.centerYAnchor),
profileButton.centerXAnchor.constraint(equalTo: bottomBar.centerXAnchor, constant: view.frame.width/3.5),
profileButton.heightAnchor.constraint(equalToConstant: 35),

这里限制的正确方法是什么？

您可能需要让autoLayout知道您想要宽度灵活。您可以通过在两个按钮定义上添加以下行来做到这一点：-

// Replace "myButton" with your buttons name in your case "v"
 myButton.autoresizingMask = [.flexibleWidth]
