我一直沒有成功將我的自定義UIView添加到我的TableViewCell。此自定義視圖表示每個表視圖單元格的自定義複選標記。我正在做我的項目沒有故事板,我不知道如何以編程方式將此自定義UIView添加到我的UITableViewCell。這裏是我的代碼:將自定義UIView添加到TableViewCell
class CheckBoxView: UIView {
var isChecked: Bool
var checkBoxImageView: UIImageView
var checkBoxChanged :() ->() = { }
required init?(coder aDecoder: NSCoder) {
self.isChecked = false
self.checkBoxImageView = UIImageView(image: nil)
super.init(coder: aDecoder)
setup()
}
func setup() {
self.layer.borderWidth = 1.0
self.isUserInteractionEnabled = true
self.checkBoxImageView.frame = CGRect(x: 2, y: 2, width: 25, height: 25)
self.addSubview(self.checkBoxImageView)
let selector: Selector = "checkBoxTapped"
let tapRecognizer = UITapGestureRecognizer(target: self, action: selector)
self.addGestureRecognizer(tapRecognizer)
}
func checkBoxTapped() {
self.checkBoxChanged()
}
func markAsChecked() {
self.checkBoxImageView.image = UIImage(named: "new_message_icon")
}
func markAsUnChecked() {
self.checkBoxImageView.image = nil
}
}
這裏是我的TableViewCell:
class AddContactsCell: UITableViewCell {
let profileImageView: UIImageView = {
let imageView = UIImageView()
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.layer.cornerRadius = 20
imageView.layer.masksToBounds = true
imageView.contentMode = .scaleAspectFill
return imageView
}()
let checkBox: CheckBoxView = {
let view = UIView() as! CheckBoxView
view.backgroundColor = UIColor.blue
view.translatesAutoresizingMaskIntoConstraints = false
view.layer.cornerRadius = 16
view.layer.masksToBounds = true
return view
}()
override func layoutSubviews() {
super.layoutSubviews()
textLabel?.frame = CGRect(x: 100, y: textLabel!.frame.origin.y - 2, width: textLabel!.frame.width, height: textLabel!.frame.height)
detailTextLabel?.frame = CGRect(x: 101, y: detailTextLabel!.frame.origin.y + 1, width: detailTextLabel!.frame.width, height: detailTextLabel!.frame.height)
}
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: .subtitle, reuseIdentifier: reuseIdentifier)
addSubview(profileImageView)
self.addSubview(checkBox)
//ios 9 constraint anchors
//need x,y,width,height anchors
profileImageView.leftAnchor.constraint(equalTo: self.leftAnchor, constant: 50).isActive = true
profileImageView.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
profileImageView.widthAnchor.constraint(equalToConstant: 40).isActive = true
profileImageView.heightAnchor.constraint(equalToConstant: 40).isActive = true
checkBox.leftAnchor.constraint(equalTo: self.leftAnchor, constant: 10).isActive = true
checkBox.centerYAnchor.constraint(equalTo: self.centerYAnchor).isActive = true
checkBox.widthAnchor.constraint(equalToConstant: 30).isActive = true
checkBox.heightAnchor.constraint(equalToConstant: 30).isActive = true
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
我真的很感激,如果你能告訴我在哪裏,我與添加的UIView走錯了。
哪裏是你的'cellForRow'方法? –
方明寧它在我的桌子,但我沒有發佈它,因爲它是很多代碼 – ajayb
好的。所以你的圖像視圖被正確添加,但不是你的自定義視圖,對吧? –
