[英]How to put a floating action button in a tableView in swift in iOS?
我正在尝试使用 iOS 中的浮动操作按钮来强加表视图,以便我可以使用该按钮在表视图中添加项目。 请帮我写代码。
这是它的完整代码。 它是在不使用故事板的情况下完成的。
表视图:
import UIKit
class ViewController: UIViewController, UITableViewDataSource {
let nameArray = ["India","Usa","UK"]
let tableView: UITableView = {
let table = UITableView()
table.translatesAutoresizingMaskIntoConstraints = false
return table
}()
let btnFloating : UIButton = {
let floating = UIButton()
floating.translatesAutoresizingMaskIntoConstraints = false
floating .backgroundColor = .cyan
floating.setTitle("ADD", for: .normal)
return floating
}()
override func viewDidLoad() {
super.viewDidLoad()
view.addSubview(tableView)
tableView.addSubview(btnFloating)
tableView.dataSource = self
setuoConstrain()
//Set the action of add button
btnFloating.addTarget(self, action: #selector(btnAddTapp(sender:)), for: .touchUpInside)
}
func setuoConstrain(){
tableView.topAnchor.constraint(equalTo: view.topAnchor).isActive = true
tableView.leadingAnchor.constraint(equalTo: view.leadingAnchor).isActive = true
tableView.trailingAnchor.constraint(equalTo: view.trailingAnchor).isActive = true
tableView.bottomAnchor.constraint(equalTo: view.bottomAnchor).isActive = true
//Constrain For Button :
btnFloating.heightAnchor.constraint(equalToConstant: 64).isActive = true
btnFloating.widthAnchor.constraint(equalToConstant: 64).isActive = true
btnFloating.trailingAnchor.constraint(equalTo: view.trailingAnchor, constant: -24).isActive = true
btnFloating.bottomAnchor.constraint(equalTo: self.view.bottomAnchor, constant: -36).isActive = true
}
//This function is for add button . What action you want , can put inside this function
@objc func btnAddTapp(sender: UIButton){
print("add button tapp")
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return nameArray.count
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let nameCell = NameTableCell(style: .default, reuseIdentifier: "NameTableCell")
nameCell.lblName.text = nameArray[indexPath.row]
return nameCell
}
}
表视图单元格:
import UIKit
class NameTableCell: UITableViewCell {
let lblName: UILabel = {
let name = UILabel()
name.translatesAutoresizingMaskIntoConstraints = false
return name
}()
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
self.addSubview(lblName)
constrain()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func constrain(){
lblName.centerXAnchor.constraint(equalTo: self.centerXAnchor).isActive = true
}
}
func setupFloatingActionButton() {
Floaty.global.button.buttonImage = UIImage(named: "icon-social")
Floaty.global.button.buttonColor = UIColor.white
let facebookItem = FloatyItem()
facebookItem.icon = UIImage(named: "icon-facebook")
facebookItem.title = "Facebook"
Floaty.global.button.addItem(item: facebookItem)
let gmailItem = FloatyItem()
Floaty.global.button.addItem("Gmail", icon: UIImage(named: "icon-gmail"), handler: {_
in
print("Gmail Button tapp")
})
let twitterItem = FloatyItem()
Floaty.global.button.addItem("Twitter", icon: UIImage(named: "icon-twitter"), handler: {_ in
print("twitter Button tapp")
})
//Floaty.global.button.animationSpeed = 0.50
Floaty.global.button.openAnimationType = .fade
//Floaty.global.button.rotationDegrees = 90.00
Floaty.global.show()
}
