我希望在点击图像时对其进行动画处理,到目前为止,这是我的代码,当我点击图像时由于某种原因什么也没发生。
lazy var profileImageView: UIImageView = {
let imageView = UIImageView()
imageView.image = UIImage(named: "made")
imageView.translatesAutoresizingMaskIntoConstraints = false
imageView.contentMode = .scaleAspectFill
imageView.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(taptap)))
imageView.isUserInteractionEnabled = true
return imageView
}()
@objc func taptap() {
let pulse = CASpringAnimation(keyPath: "transform.scale")
pulse.duration = 0.6
pulse.fromValue = 0.95
pulse.toValue = 1.0
pulse.autoreverses = true
pulse.repeatCount = 2
pulse.initialVelocity = 0.5
pulse.damping = 1.0
layer.add(pulse, forKey: nil)
}
答案 0 :(得分:0)
除了在ImageView
行中添加动画之外,其他所有内容都看起来不错。替换此行:
layer.add(pulse, forKey: nil)
使用:
profileImageView.layer.add(pulse, forKey: nil)
您需要在视图的Core Animations
中添加layer
,这里是您的profileImageView
。
