[英]UIButton in UICollectionViewHeader doesn't work
编辑:该代码在单元格的正文中工作,但不在标题中!
我已经以编程方式向我的视图添加了一个按钮。 一切都正确显示。 当我按下按钮时,它会突出显示。 问题在于该函数没有被调用。 有人有解决问题的想法吗?
let addPerson : UIButton = {
let btn = UIButton(type: .system)
btn.setTitle("Test button", for: .normal)
btn.setTitleColor(.white, for: .normal)
btn.backgroundColor = .darkGray
btn.layer.masksToBounds = true
btn.addTarget(self, action: #selector(handleAddPerson), for: .touchUpInside)
btn.translatesAutoresizingMaskIntoConstraints = false
return btn
}()
@objc func handleAddPerson() {
print("test")
}
//Following is inside the init
let stackView = UIStackView(arrangedSubviews: [addPerson,addGroup])
stackView.distribution = .fillEqually
stackView.translatesAutoresizingMaskIntoConstraints = false
stackView.spacing = 10
addSubview(stackView)
NSLayoutConstraint.activate([
stackView.topAnchor.constraint(equalTo: topAnchor, constant: 8),
stackView.bottomAnchor.constraint(equalTo: bottomAnchor, constant: -8),
stackView.leadingAnchor.constraint(equalTo: leadingAnchor, constant: 8),
stackView.trailingAnchor.constraint(equalTo: trailingAnchor, constant: -8),
])
尝试将选择器更改为该配合:
@objc func handleAddPerson(_ sender: UIButton?) {
print("test")
}
