我想自定义我的 UICollectionViewCell
,但它无法按照我希望的方式工作。
这是第一个单元格的代码:
class MainWishlistCell: UICollectionViewCell {
let wishlistImage: UIImageView = {
let v = UIImageView()
v.translatesAutoresizingMaskIntoConstraints = false
v.image = UIImage(named: "logoGroß")
v.layer.cornerRadius = 3.0
v.layer.shadowColor = UIColor.black.cgColor
v.layer.shadowOffset = CGSize(width: 3, height: 3)
v.layer.masksToBounds = false
return v
}()
let wishlistLabel: UILabel = {
let v = UILabel()
v.translatesAutoresizingMaskIntoConstraints = false
v.text = "Main Wishlist"
v.font = UIFont(name: "Avenir Next-Bold", size: 18)
v.textColor = .darkGray
v.textAlignment = .center
return v
}()
override init(frame: CGRect) {
super.init(frame: frame)
commonInit()
}
required init?(coder: NSCoder) {
super.init(coder: coder)
commonInit()
}
func commonInit() -> Void {
contentView.addSubview(wishlistImage)
contentView.addSubview(wishlistLabel)
// constrain view to all 4 sides
NSLayoutConstraint.activate([
wishlistImage.topAnchor.constraint(equalTo: contentView.topAnchor),
wishlistImage.leadingAnchor.constraint(equalTo: contentView.leadingAnchor),
wishlistImage.trailingAnchor.constraint(equalTo: contentView.trailingAnchor),
wishlistImage.heightAnchor.constraint(equalToConstant:150),
wishlistLabel.topAnchor.constraint(equalTo: wishlistImage.bottomAnchor,constant: 1),
wishlistLabel.bottomAnchor.constraint(equalTo: contentView.bottomAnchor),
wishlistLabel.leadingAnchor.constraint(equalTo: contentView.leadingAnchor),
wishlistLabel.trailingAnchor.constraint(equalTo: contentView.trailingAnchor),
])
}
}
它看起来像这样:
<强>1。问题 - 为什么标签不是粗体
?
<强>2。问题 - 为什么没有cornerRadius
?
<强>3。问题 - 为什么 shadow
没有出现(底部 + 右侧)?
最佳答案
对于你的第一个问题,@pigeon_39 说你应该在没有空格的情况下写下你的字体名称。
对于第二个和第三个问题,可以使用这个解决方法:
func addShadow() {
let cornerRadius: CGFloat = 5
self.wishlistImage.layer.shadowPath = UIBezierPath(roundedRect: self.wishlistImage.bounds, cornerRadius: cornerRadius).cgPath
self.wishlistImage.layer.shadowRadius = cornerRadius
self.wishlistImage.layer.shadowOffset = .zero
self.wishlistImage.layer.shadowOpacity = 0.3
self.wishlistImage.layer.shadowRadius = 10
self.wishlistImage.layer.cornerRadius = cornerRadius
self.wishlistImage.layer.shadowColor = UIColor.black.cgColor
}
并在设置约束后调用。
