我想将图像设置为UIImage,但是一旦我设置它,UIImageView就会变得更大并且会越过其他元素。
这里有一个解决方案:Crop UIImage to fit a frame image
但我不能让它工作,我在提供的解决方案中设置属性。
也许有人可以看看并帮助我:
没有设置图像:
class Cell: UICollectionViewCell, CollectionViewCellConfigurable {
var image = UIImageView()
var dateDay = UILabel()
var dateMonth = UILabel()
var title = UILabel()
lazy private var dateContainer: UIView = {
let v = UIView()
v.sv(dateDay, dateMonth)
dateDay.heightAnchor.constraint(equalTo: self.dateMonth.heightAnchor, multiplier: 1).isActive = true
dateDay.leadingAnchor.constraint(equalTo: v.leadingAnchor, constant: 5).isActive = true
dateDay.trailingAnchor.constraint(equalTo: v.trailingAnchor, constant: -5).isActive = true
dateDay.topAnchor.constraint(equalTo: v.topAnchor, constant: 15).isActive = true
dateDay.bottomAnchor.constraint(equalTo: dateMonth.topAnchor, constant: -5).isActive = true
dateMonth.heightAnchor.constraint(equalTo: self.dateDay.heightAnchor, multiplier: 1).isActive = true
dateMonth.leadingAnchor.constraint(equalTo: v.leadingAnchor, constant: 5).isActive = true
dateMonth.trailingAnchor.constraint(equalTo: v.trailingAnchor, constant: -5).isActive = true
dateMonth.topAnchor.constraint(equalTo: dateDay.bottomAnchor, constant: 5).isActive = true
// dateMonth.bottomAnchor.constraint(greaterThanOrEqualTo: v.bottomAnchor, constant: -5).isActive = true
return v
}()
lazy private var container: UIView = {
return UIView()
}()
func configureCellAtIndexPath(item: Journaling) {
self.image.image = UIImage.baliBeach
self.image.backgroundColor = .green
self.dateDay.text = "16"
self.dateMonth.text = "May"
self.title.text = "Text visible"
}
override init(frame: CGRect) {
super.init(frame:frame)
setUpLayout()
additionalSetUp()
}
required init(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func additionalSetUp() {
backgroundColor = .clear
let colorText: UIColor = .grau
dateDay.textColor = colorText
dateMonth.textColor = colorText
title.textColor = colorText
dateDay.textAlignment = .center
dateMonth.textAlignment = .center
title.textAlignment = .center
image.contentMode = .scaleAspectFill
image.clipsToBounds = true
image.autoresizesSubviews = true
}
func setUpLayout() {
sv(dateContainer, container)
container.sv(image,title)
dateContainer.widthAnchor.constraint(equalToConstant: 45).isActive = true
// dateContainer.widthAnchor.constraint(equalTo: self.widthAnchor, multiplier: 0.15).isActive = true
dateContainer.leadingAnchor.constraint(equalTo: self.leadingAnchor, constant: 0).isActive = true
dateContainer.trailingAnchor.constraint(equalTo: container.leadingAnchor, constant: 0).isActive = true
dateContainer.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
dateContainer.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
// container.widthAnchor.constraint(equalTo: self.widthAnchor, multiplier: 0.5).isActive = true
container.leadingAnchor.constraint(equalTo: dateContainer.trailingAnchor, constant: 0).isActive = true
container.trailingAnchor.constraint(equalTo: self.trailingAnchor, constant: 0).isActive = true
container.topAnchor.constraint(equalTo: self.topAnchor, constant: 0).isActive = true
container.bottomAnchor.constraint(equalTo: self.bottomAnchor, constant: 0).isActive = true
image.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant: 5).isActive = true
image.trailingAnchor.constraint(equalTo: container.trailingAnchor, constant: -5).isActive = true
image.topAnchor.constraint(equalTo: self.topAnchor, constant: 15).isActive = true
image.bottomAnchor.constraint(equalTo: title.topAnchor, constant: -5).isActive = true
title.leadingAnchor.constraint(equalTo: container.leadingAnchor, constant: 0).isActive = true
title.trailingAnchor.constraint(equalTo: container.trailingAnchor, constant: 0).isActive = true
title.topAnchor.constraint(equalTo: image.bottomAnchor, constant: 5).isActive = true
title.bottomAnchor.constraint(equalTo: container.bottomAnchor, constant: 0).isActive = true
}
}
您需要更高的标题标签垂直压缩优先级,因为imageView等于它= 750,因此占用空间
title.setContentCompressionResistancePriority(UILayoutPriority(rawValue: 751), for: .vertical)
