如何解决UIImageView 未按圆形调整大小,UILabel 未在 StackView 和自定义集合单元中调整大小
然而,我正在尝试将我的 UIImageView
调整为一个圆圈;每次我尝试调整与 UIImageView
一起位于 StackView 内的 UILabel
的大小时,我都会以更矩形的形状结束。有人可以告诉我我哪里出错了我已经坚持了好几天了吗?下面是我的代码,它试图做的是添加底部带有标签的图像,图像应该是圆形的,这应该是我的集合视图控制器。
自定义集合视图单元
import UIKit
class CarerCollectionViewCell: UICollectionViewCell {
static let identifier = "CarerCollectionViewCell"
private let imageView: UIImageView = {
let imageView = UIImageView()
imageView.frame = CGRect(x: 0,y: 0,width: 20,height: 20);
//imageView.center = imageView.superview!.center;
imageView.contentMode = .scaleAspectFill
imageView.layer.borderWidth = 4
imageView.layer.masksToBounds = false
imageView.layer.borderColor = UIColor.orange.cgColor
imageView.layer.cornerRadius = imageView.frame.height / 2
return imageView
}()
private let carerNamelabel: UILabel = {
let carerNamelabel = UILabel()
carerNamelabel.layer.masksToBounds = false
carerNamelabel.font = .systemFont(ofSize: 12)
carerNamelabel.textAlignment = .center
carerNamelabel.layer.frame = CGRect(x: 0,width: 50,height: 50);
return carerNamelabel
}()
private let stackView: UIStackView = {
let stackView = UIStackView()
stackView.layer.masksToBounds = false
stackView.axis = .vertical
stackView.alignment = .center
stackView.backgroundColor = .systemOrange
stackView.distribution = .fillProportionally
stackView.translatesAutoresizingMaskIntoConstraints = false
return stackView
}()
override init(frame: CGRect) {
super.init(frame: frame)
configureContentView()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
}
private func configureContentView() {
imageView.clipsToBounds = true
stackView.clipsToBounds = true
carerNamelabel.clipsToBounds = true
contentView.addSubview(stackView)
configureStackView()
}
private func configureStackView() {
allContraints()
stackView.addArrangedSubview(imageView)
stackView.addArrangedSubview(carerNamelabel)
}
private func allContraints() {
setStackViewConstraint()
}
private func setStackViewConstraint() {
stackView.widthAnchor.constraint(equalTo: contentView.widthAnchor).isActive = true
stackView.heightAnchor.constraint(equalTo: contentView.heightAnchor).isActive = true
stackView.centerXAnchor.constraint(equalTo: contentView.centerXAnchor).isActive = true
stackView.centerYAnchor.constraint(equalTo: contentView.centerYAnchor).isActive = true
}
public func configureImage(with imageName: String,andImageName labelName: String) {
imageView.image = UIImage(named: imageName)
carerNamelabel.text = labelName
}
override func layoutSubviews() {
super.layoutSubviews()
stackView.frame = contentView.bounds
}
override func prepareForReuse() {
super.prepareForReuse()
imageView.image = nil
carerNamelabel.text = nil
}
}
下面是我的 CollectionViewControler 代码
自定义集合视图
import UIKit
class CarerViewController: UIViewController,UICollectionViewDelegate,UICollectionViewDataSource,UICollectionViewDelegateFlowLayout {
private var collectionView: UICollectionView = {
let layout = UICollectionViewFlowLayout()
layout.scrollDirection = .vertical
layout.itemSize = CGSize(width: 120,height: 120)
let collectionView = UICollectionView(frame: .zero,collectionViewLayout: layout)
collectionView.register(CarerCollectionViewCell.self,forCellWithReuseIdentifier: CarerCollectionViewCell.identifier)
collectionView.showsVerticalScrollIndicator = false
collectionView.backgroundColor = .clear
return collectionView
}()
override func viewDidLoad() {
super.viewDidLoad()
collectionView.delegate = self
collectionView.dataSource = self
view.addSubview(collectionView)
collectionView.translatesAutoresizingMaskIntoConstraints = false
// Layout constraints for `collectionView`
NSLayoutConstraint.activate([
collectionView.widthAnchor.constraint(equalTo: view.widthAnchor),collectionView.heightAnchor.constraint(lessThanOrEqualTo: view.heightAnchor,constant: 600),collectionView.topAnchor.constraint(equalTo: view.topAnchor,constant: 200),collectionView.leadingAnchor.constraint(equalTo: view.leadingAnchor)
])
}
func collectionView(_ collectionView: UICollectionView,numberOfItemsInSection section: Int) -> Int {
return 10
}
func collectionView(_ collectionView: UICollectionView,cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
let cell = collectionView.dequeueReusableCell(withReuseIdentifier: CarerCollectionViewCell.identifier,for: indexPath) as! CarerCollectionViewCell
cell.configureImage(with: "m7opt04g_ms-dhoni-afp_625x300_06_July_20",andImageName: "IMAGE NO. 1")
return cell
}
}
谁能告诉我我做错了什么,谢谢 This is what I am trying to achieve
解决方法
UIStackView
有时可能很棘手,您可以将 UIImageView
嵌入到 UIView
中,并将布局代码移动到 viewWillLayoutSubviews()
,这也意味着 {{1} }} 也将其嵌入到 UILabel
中,因此容器 UIView
将有一个静态框架,以便 UIView
正确布局,其中的内容只会影响自身。
