如何在堆栈视图中设置按钮的宽度
How to set the width of a button in a stack view
大家好,我正在尝试使用 NSLayoutConstraints 以编程方式设置按钮的宽度。
这是我的按钮:
private let testBtn: UIButton = {
let button = UIButton(type: .system)
button.setTitle("Test", for: .normal)
button.translatesAutoresizingMaskIntoConstraints = false
button.titleLabel?.font = UIFont.boldSystemFont(ofSize: 28)
button.setTitleColor(.white, for: .normal)
button.backgroundColor = .red
return button
}()
这里是我设置堆栈视图及其约束的地方:
fileprivate func setupButton() {
let ButtonStackView = UIStackView(arrangedSubviews: [ViewBtn])
ButtonStackView.translatesAutoresizingMaskIntoConstraints = false
view.addSubview(ButtonStackView)
NSLayoutConstraint.activate([
ButtonStackView.bottomAnchor.constraint(equalTo: view.bottomAnchor, constant: -100),
ButtonStackView.leadingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.leadingAnchor),
ButtonStackView.trailingAnchor.constraint(equalTo: view.safeAreaLayoutGuide.trailingAnchor),
ButtonStackView.heightAnchor.constraint(equalToConstant: 50)
])
}
如何调整按钮的宽度并设置为圆角按钮?
谢谢!
以下是添加宽度约束以测试 Button 的方法
testBtn.widthAnchor.constraint(equalToConstant: 100).isActive = true
圆角你使用
testBtn.layer.cornerRadius = testBtn.bounds.maxY/2
注意:viewDidLayoutSubviews()
