我试图将包含自定义视图(每个都有一个图标和一个多行标签)的UIStackView
放入一个UITableViewCell
中。
这是我尝试过的:
CustomView.swift
enum Icon {
case eye
case location
case paper
case phone
var image: UIImage {
switch self {
case .eye:
return UIImage(named: "EyeIcon")!
case .location:
return UIImage(named: "PaperPlaneIcon")!
case .paper:
return UIImage(named: "PhoneIcon")!
case .phone:
return UIImage(named: "PinLocationIcon")!
}
}
}
class TestView: UIView {
@IBOutlet var contentView: UIView!
@IBOutlet weak var iconView: UIImageView!
@IBOutlet weak var label: UILabel!
var icon: Icon? {
didSet {
iconView.image = icon?.image
}
}
var text: String? {
didSet {
label.text = text
}
}
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
commonInit()
}
private func commonInit() {
Bundle.main.loadNibNamed("TestView", owner: self, options: nil)
addSubview(contentView)
contentView.frame = self.bounds
contentView.autoresizingMask = [.flexibleWidth, .flexibleHeight]
}
}
CustomView.xib
在控制器的cellForRow()
方法中:
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let fruit = fruits[indexPath.row]
let cell = tableView.dequeueReusableCell(withIdentifier: "CellTest", for: indexPath) as! CellTest
cell.colorView.backgroundColor = fruit.color
cell.titleLabel.text = fruit.name
cell.regionLabel.text = fruit.region
if let eyeInfo = fruit.eyeInfo {
let view = TestView()
view.icon = .eye
view.text = eyeInfo
cell.stackView.addArrangedSubview(view)
}
if let locationInfo = fruit.locationInfo {
let view = TestView()
view.icon = .location
view.text = locationInfo
cell.stackView.addArrangedSubview(view)
}
if let paperInfo = fruit.paperInfo {
let view = TestView()
view.icon = .paper
view.text = paperInfo
cell.stackView.addArrangedSubview(view)
}
if let phoneInfo = fruit.phoneInfo {
let view = TestView()
view.icon = .phone
view.text = phoneInfo
cell.stackView.addArrangedSubview(view)
}
return cell
}
关联单元格的xib:
结果如下:
如果我将Fill
替换为Fill Equally/Proportionally
:
我不知道如何改善它并使它正常工作。
谢谢您的帮助!

要使用单元格原型获得所需的布局(请注意:我从发布的图像中裁剪了“ icon”图像,因此它们的分辨率较低)...
“彩色”视图,标题标签和区域标签是非常标准的布局。
下面是垂直的Stack View
。对齐方式:填充,分布:填充,间距:8.从左向左进一步限制,顶部是彩色视图底部的12点,尾随是0(至页边距)。没有高度限制。底部从内容视图的底部受约束>= 8
(这样可以轻松避免情节提要约束警告)。
该垂直堆栈视图中的每个“行”都是一个水平堆栈视图。对齐方式:顶部,分布:填充,间距:20(这是图标图像视图和标签左侧之间的空间)。
图标imageViews的Width和Height都被限制为24点(我猜是您的大小-请根据需要进行调整)。
“眼睛堆栈”的标签设置为Number Of Lines: 0
-使其可以垂直扩展。
关于堆栈视图的妙处在于,如果将子视图设置为隐藏,则堆栈视图将布局其余的子视图,就像隐藏视图不在那里一样。
所以,一些代码...
我将Fruit
对象定义为:
class Fruit: NSObject {
var color: UIColor?
var name: String?
var region: String?
var eyeInfo: String?
var locationInfo: String?
var paperInfo: String?
var phoneInfo: String?
}
tableview控制器类非常简单:
class FruitTableViewController: UITableViewController {
var fruits: [Fruit] = [Fruit]()
override func viewDidLoad() {
super.viewDidLoad()
var aFruit: Fruit!
// create a couple Fruit objects
aFruit = Fruit()
aFruit.color = .yellow
aFruit.name = "Banana"
aFruit.region = "Tropical"
aFruit.eyeInfo = "A banana is an edible fruit - technically a berry - produced by several kinds of large herbaceous flowering plants in the genus Musa. In some countries, bananas used for cooking may be called \"plantains\", distinguishing them from dessert bananas."
aFruit.locationInfo = "banana location"
aFruit.paperInfo = "banana paper"
aFruit.phoneInfo = "555-1212"
fruits.append(aFruit)
aFruit = Fruit()
aFruit.color = .orange
aFruit.name = "Orange"
aFruit.region = "Somewhere"
aFruit.eyeInfo = "The orange is the fruit of the citrus species Citrus × sinensis in the family Rutaceae. It is also called sweet orange, to distinguish it from the related Citrus × aurantium, referred to as bitter orange. The sweet orange reproduces asexually (apomixis through nucellar embryony); varieties of sweet orange arise through mutations."
aFruit.paperInfo = "orange paper"
aFruit.phoneInfo = "555-1234"
fruits.append(aFruit)
aFruit = Fruit()
aFruit.color = .red
aFruit.name = "Strawberry"
aFruit.region = "Somewhere else"
aFruit.eyeInfo = "The garden strawberry (or simply strawberry; Fragaria × ananassa) is a widely grown hybrid species of the genus Fragaria, collectively known as the strawberries. It is cultivated worldwide for its fruit. The fruit is widely appreciated for its characteristic aroma, bright red color, juicy texture, and sweetness. It is consumed in large quantities, either fresh or in such prepared foods as preserves, juice, pies, ice creams, milkshakes, and chocolates. Artificial strawberry flavorings and aromas are also widely used in many products like lip gloss, candy, hand sanitizers, perfume, and many others."
aFruit.paperInfo = "strawberry location"
fruits.append(aFruit)
}
// MARK: - Table view data source
override func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return fruits.count
}
override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell = tableView.dequeueReusableCell(withIdentifier: "FruitCell", for: indexPath) as! FruitCell
let fruit = fruits[indexPath.row]
// tell the cell to lay itself out using the Fruit object
cell.setData(fruit)
return cell
}
}
现在,棘手的部分(实际上不是很棘手)位于单元格类中:
class FruitCell: UITableViewCell {
@IBOutlet var colorView: UIView!
@IBOutlet var titleLabel: UILabel!
@IBOutlet var regionLabel: UILabel!
@IBOutlet var eyeStack: UIStackView!
@IBOutlet var eyeLabel: UILabel!
@IBOutlet var paperStack: UIStackView!
@IBOutlet var paperLabel: UILabel!
@IBOutlet var locationStack: UIStackView!
@IBOutlet var locationLabel: UILabel!
@IBOutlet var phoneStack: UIStackView!
@IBOutlet var phoneLabel: UILabel!
func setData(_ aFruit: Fruit) -> Void {
colorView.backgroundColor = aFruit.color ?? .clear
titleLabel.text = aFruit.name ?? "missing name"
regionLabel.text = aFruit.region ?? "missing region"
eyeLabel.text = aFruit.eyeInfo
eyeStack.isHidden = aFruit.eyeInfo == nil
paperLabel.text = aFruit.paperInfo
paperStack.isHidden = aFruit.paperInfo == nil
locationLabel.text = aFruit.locationInfo
locationStack.isHidden = aFruit.locationInfo == nil
phoneLabel.text = aFruit.phoneInfo
phoneStack.isHidden = aFruit.phoneInfo == nil
}
}
如您所见,那里并没有发生太多事情。填写字段,并隐藏任何没有关联属性的“行”。
结果:
这是我使用的情节提要的来源。创建一个新的情节提要,使用Open As... Source Code
,然后将全部内容替换为以下内容。要使其按原样运行,您需要更改的唯一事情是替换图标图像:
