将 cgrect 中的 tableview 单元格框架推到边距
push tableview cell frame in cgrect to margin
在下面的 swift 代码中,我希望将 tableview 单元格推到边缘,就像单元格左侧一样。在下面的照片中,您可以看到右侧 tableview 单元格的边距比左侧大很多。请使它们相等。

import UIKit
class ViewController: UIViewController, UITableViewDelegate, UITableViewDataSource {
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "cell", for: indexPath)
cell.textLabel?.text = "\(indexPath.row)"
return cell
}
var numberOfRows = 3
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { numberOfRows }
func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
return 118
}
var btn = UIButton()
var tableView = UITableView()
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view.
setTableVIew()
}
func setTableVIew(){
let VCframe = self.view.frame
let height = VCframe.height * 0.8
let widthx = VCframe.width
tableView.frame = CGRect(x: 0, y: 0, width: widthx, height: height)
tableView.delegate = self
tableView.dataSource = self
self.view.addSubview(tableView)
tableView.backgroundColor = .blue
tableView.register(customtv.self, forCellReuseIdentifier: "cell")
}
}
class customtv: UITableViewCell {
lazy var backView : UIView = {
let view = UIView(frame: CGRect(x: 10, y: 6, width: self.frame.width , height: 110))
view.backgroundColor = .green
print(self.frame.width)
return view
}()
override func layoutSubviews() {
backView.clipsToBounds = true
}
override func setSelected(_ selected: Bool, animated: Bool) {
super.setSelected(animated, animated: true)
addSubview(backView)
}
}
更新layoutSubviews中的View frame
class customtv: UITableViewCell {
lazy var backView : UIView = {
let view = UIView(frame: CGRect(x: 10, y: 6, width: self.frame.width , height: 110))
view.backgroundColor = .green
print(self.frame.width)
return view
}()
override func layoutSubviews() {
backView.clipsToBounds = true
backView.frame = CGRect(x: 0, y: 6, width: bounds.maxX , height: 110)
}
它们将变成等宽单元格……如果你想给边距……把它给你的表格视图而不是单元格……
tableView.frame = CGRect(x: 10, y: 0, width: widthx - 20, height: height)
