问题描述
我有几个具有相同作用的视图。我试图分解该函数,但是没有用。 这是ViewController中代码的一部分:
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,animations: { self.viewPROTEINES.transform = .identity },completion: nil)
}
@objc private func boingLIPIDES(gesture: UITapGestureRecognizer) {
viewLIPIDES.transform = CGAffineTransform(scaleX: 0.5,animations: { self.viewLIPIDES.transform = .identity },completion: nil)
}
@objc private func boingGLUCIDES(gesture: UITapGestureRecognizer) {
viewGLUCIDES.transform = CGAffineTransform(scaleX: 0.5,animations: { self.viewGLUCIDES.transform = .identity },completion: nil)
}
我尝试了一些测试,但是失败了。那么我如何将所有这些因素分解呢? 谢谢
解决方法
您可以从UITapGestureRecognizer
中检索视图。
let view = gesture.view
因此您可以这样做:
@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)
}
并进行通话分解:
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)
如果走得更远,我们可以将视图放入数组并在它们上循环:
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)
}
