只是尝试关注一些youtube教程并了解自定义视图。我相信我在这里遗漏了一些非常基本的东西。在这里和网上看了几个小时后，我放弃了。
我有一个自定义视图，可以滑出来。我打算根据需要填写不同的自定义视图。 slideOutView显示正常。但是，我无法在其中看到名为FlashCardView的其他自定义视图。我从SlideOutView调用FlashCardView。
感谢您的帮助！
FlashCardView类的代码：
import UIKit
protocol FlashCardViewDelegate: class {
}
class FlashCardView: UIView {
weak var delegate: FlashCardViewDelegate?
let questionLabel = UILabel()
let scrollView = UIScrollView()
let dummyView = UIView()
//MARK: Initialization
override init(frame: CGRect) {
super.init(frame: frame)
self.backgroundColor = UIColor.black
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
}
SlideOutView类的代码：
import UIKit
class SlideOutView: UIView {
let slideOutView = UIView()
let menuBarLine = UIView()
let menuBarView = UIView()
let menuButton = UIButton()
let backButton = UIButton()
let flashCardView = FlashCardView()
let ratio = DeviceSpecificValues()
override init(frame: CGRect) {
super.init(frame: frame)
self.addView()
}
required init?(coder aDecoder: NSCoder) {
fatalError("init(coder:) has not been implemented")
}
func addView() {
if let window = UIApplication.shared.keyWindow {
slideOutView.frame = CGRect(x: 0, y: window.bounds.height, width: window.bounds.width, height: window.bounds.height / 2)
print("slideoutview frame is: \(slideOutView.frame)")
slideOutView.backgroundColor = UIColor.white
window.addSubview(slideOutView)
menuBarView.frame = CGRect(x: 0, y: 0, width: slideOutView.bounds.width, height: window.bounds.height / ratio.menuBarRatio)
menuBarView.backgroundColor = GlobalValues.menuBarViewColor
slideOutView.addSubview(menuBarView)
menuBarLine.frame = CGRect(x: 0, y: 0, width: menuBarView.bounds.width, height: GlobalValues.menuBarLineWidth)
menuBarLine.backgroundColor = GlobalValues.menuTextColor
menuBarView.addSubview(menuBarLine)
backButton.frame = CGRect(x: 0, y: 0, width: menuBarView.bounds.width * 0.1, height: menuBarView.bounds.height * 0.9)
backButton.center.y = menuBarView.bounds.height / 2 + GlobalValues.menuBarLineWidth
backButton.setTitle("<Back", for: .normal)
backButton.titleLabel?.adjustsFontSizeToFitWidth = true
backButton.setTitleColor(GlobalValues.menuTextColor, for: UIControlState())
backButton.showsTouchWhenHighlighted = true
menuBarView.addSubview(backButton)
menuButton.frame = CGRect(x: menuBarView.bounds.width * 0.9, y: 0, width: menuBarView.bounds.width * 0.1, height: menuBarView.bounds.height * 0.9)
menuButton.center.y = menuBarView.bounds.height / 2 + GlobalValues.menuBarLineWidth
menuButton.setTitle("Menu", for: .normal)
menuButton.titleLabel?.adjustsFontSizeToFitWidth = true
menuButton.setTitleColor(GlobalValues.menuTextColor, for: UIControlState())
menuButton.showsTouchWhenHighlighted = true
menuBarView.addSubview(menuButton)
addFlashCardView()
}
}
func slideIn() {
UIView.animate(withDuration: 0.5, delay: 0.0, options: .curveLinear, animations: {
if let window = UIApplication.shared.keyWindow {
self.slideOutView.frame = CGRect(x: 0, y: window.bounds.height, width: window.bounds.width, height: window.bounds.height / 2)
}
}, completion: nil)
}
func slideOut() {
UIView.animate(withDuration: 0.5, delay: 0.0, options: .curveLinear, animations: {
if let window = UIApplication.shared.keyWindow {
self.slideOutView.frame = CGRect(x: 0, y: window.bounds.height / 2, width: window.bounds.width, height: window.bounds.height / 2)
}
}, completion: nil)
}
func addFlashCardView() {
flashCardView.frame = slideOutView.frame
slideOutView.addSubview(flashCardView)
}
