如何分解包含选择器的函数?
how to factorize a function including a selector?
我有几个视图具有相同的操作。我试图分解这个函数,但没有成功。
这是 ViewController:
中的部分代码
class MenuViewController: UIViewController {
@IBOutlet weak var addButton: FloatingActionButton!
@IBOutlet weak var viewCALORIES: UIView!
@IBOutlet weak var viewPROTEINES: UIView!
@IBOutlet weak var viewLIPIDES: UIView!
@IBOutlet weak var viewGLUCIDES: UIView!
override func viewDidLoad() {
super.viewDidLoad()
// BoingCalories Protéines Lipides Glucides
let tapCalories = UITapGestureRecognizer(target: self, action: #selector(boingCALORIES(gesture:)))
viewCALORIES.addGestureRecognizer(tapCalories)
let tapProteines = UITapGestureRecognizer(target: self, action: #selector(boingPROTEINES(gesture:)))
viewPROTEINES.addGestureRecognizer(tapProteines)
let tapLipides = UITapGestureRecognizer(target: self, action: #selector(boingLIPIDES(gesture:)))
viewLIPIDES.addGestureRecognizer(tapLipides)
let tapGlucides = UITapGestureRecognizer(target: self, action: #selector(boingGLUCIDES(gesture:)))
viewGLUCIDES.addGestureRecognizer(tapGlucides)
}
@objc private func boingCALORIES(gesture: UITapGestureRecognizer) {
viewCALORIES.transform = CGAffineTransform(scaleX: 0.5, y: 0.5)
UIView.animate(withDuration: 0.6, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0.4, options: [], animations: { self.viewCALORIES.transform = .identity }, completion: nil)
}
@objc private func boingPROTEINES(gesture: UITapGestureRecognizer) {
viewPROTEINES.transform = CGAffineTransform(scaleX: 0.5, y: 0.5)
UIView.animate(withDuration: 0.6, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0.4, options: [], animations: { self.viewPROTEINES.transform = .identity }, completion: nil)
}
@objc private func boingLIPIDES(gesture: UITapGestureRecognizer) {
viewLIPIDES.transform = CGAffineTransform(scaleX: 0.5, y: 0.5)
UIView.animate(withDuration: 0.6, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0.4, options: [], animations: { self.viewLIPIDES.transform = .identity }, completion: nil)
}
@objc private func boingGLUCIDES(gesture: UITapGestureRecognizer) {
viewGLUCIDES.transform = CGAffineTransform(scaleX: 0.5, y: 0.5)
UIView.animate(withDuration: 0.6, delay: 0, usingSpringWithDamping: 0.3, initialSpringVelocity: 0.4, options: [], animations: { self.viewGLUCIDES.transform = .identity }, completion: nil)
}
我尝试了一些测试,但都失败了。那么我怎么能分解所有这些呢?
谢谢
从 UITapGestureRecognizer
,您可以检索视图。
let view = gesture.view
所以你可以这样做:
@objc private func boingView(gesture: UITapGestureRecognizer) {
let view = gesture.view
view.transform = CGAffineTransform(scaleX: 0.5, y: 0.5)
UIView.animate(withDuration: 0.6,
delay: 0,
usingSpringWithDamping: 0.3,
initialSpringVelocity: 0.4,
options: [],
animations: { view.transform = .identity },
completion: nil)
}
并分解调用:
let action = #selector(boingView(gesture:))
let tapCalories = UITapGestureRecognizer(target: self, action: action)
viewCALORIES.addGestureRecognizer(tapCalories)
let tapProteines = UITapGestureRecognizer(target: self, action: action)
viewPROTEINES.addGestureRecognizer(tapProteines)
let tapLipides = UITapGestureRecognizer(target: self, action: action)
viewLIPIDES.addGestureRecognizer(tapLipides)
let tapGlucides = UITapGestureRecognizer(target: self, action: action)
viewGLUCIDES.addGestureRecognizer(tapGlucides)
如果我们更进一步,我们可以将视图放入一个数组中并在它们上循环:
let views = [viewCALORIES, viewPROTEINES, viewLIPIDES, viewGLUCIDES]
let action = #selector(boingView(gesture:))
views.forEach { aView in
let tap = UITapGestureRecognizer(target: self, action: action)
aView.addGestureRecognizer(tap)
}
