[英]Rows in table view do not expand the width of it and are stacked Swift
我花了一個小時試圖弄清楚我做錯了什么,但沒有成功。 下面是代碼和結果的圖像。 在表格的第一行中,所有行都在另一個之上出現。 並且該行不會像我在約束中設置的那樣擴展表格的寬度。 我究竟做錯了什么? 謝謝你。 表視圖 class:
class TableViewListType: UITableView {
override init(frame: CGRect, style: UITableView.Style) {
super.init(frame: frame, style: style)
translatesAutoresizingMaskIntoConstraints = false
allowsSelection = true
allowsMultipleSelection = false
allowsSelectionDuringEditing = true
allowsMultipleSelectionDuringEditing = true
dragInteractionEnabled = false
backgroundColor = .clear
separatorColor = .white
separatorInset = UIEdgeInsets(top: 0, left: 0, bottom: 0, right: 0)
indicatorStyle = .white
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
表格視圖的行類:

風投:
fileprivate var experienceForProfile = [ExperienceModelForProfileAttributes(jobTitle: "Tester", companyName: "Testing Company", startedWork: "May 2019", finishedWork: "October 2019"), ExperienceModelForProfileAttributes(jobTitle: "Welder", companyName: "Welding Company", startedWork: "January 2018", finishedWork: "May 2020")]
fileprivate var skillsForProfile = [SkillsModelForProfileAttributes]()
fileprivate var educationForProfile = [EducationModelForProfileAttributes]()
fileprivate lazy var tableForAttributes: TableViewListType = {
let table = TableViewListType(frame: .zero, style: .plain)
table.delegate = self
table.dataSource = self
return table
}()
override func viewDidLoad() {
super.viewDidLoad()
navigationController?.navigationBar.isHidden = true
tableForAttributes.register(RowForExperienceInProfileTable.self, forCellReuseIdentifier: firstIDForTable)
tableForAttributes.register(RowForSkillInProfileTable.self, forCellReuseIdentifier: secondIDForTable)
tableForAttributes.register(RowForEducationInProfileTable.self, forCellReuseIdentifier: thirdIDForTable)
}
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
var numberOfRows = 0
switch selectedMimicIndex {
case 0: numberOfRows = experienceForProfile.count
case 1: numberOfRows = skillsForProfile.count
case 2: numberOfRows = educationForProfile.count
default: print("nu such rows for attributes table in own profile")
}
return numberOfRows
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
switch selectedMimicIndex {
case 0: let cell = tableView.dequeueReusableCell(withIdentifier: firstIDForTable, for: indexPath) as! RowForExperienceInProfileTable
cell.valueForExperienceRow = experienceForProfile[indexPath.row]
return cell
case 1: let cell = tableView.dequeueReusableCell(withIdentifier: secondIDForTable, for: indexPath) as! RowForSkillInProfileTable
cell.valueForSkillRow = skillsForProfile[indexPath.row]
return cell
case 2: let cell = tableView.dequeueReusableCell(withIdentifier: thirdIDForTable, for: indexPath) as! RowForEducationInProfileTable
cell.valueForEducationRow = educationForProfile[indexPath.row]
return cell
default: return UITableViewCell()
}
}
selectedMimicIndex 值更改為我擁有的集合視圖的 didSelectItem() function; 一個 cv 控制表格顯示的單元格。 當用戶更改選定的 cv 單元格時,在更改 Int 值后,此處調用 reloadData()。 還要注意第二行比它應該高得多; 忽略我指定的高度。
對於每個 label 您需要設置並將其添加到 contentView
firstLabel.translatesAutoresizingMaskIntoConstraints = false
contentView.addSubview(firstLabel)
也是最底部的 label 到電池底部
fourthLabel.bottomAnchor.constraint(equalTo:self.contentView.bottomAnchor, constant:-20)
