问题描述
当我从另一个类中调用识别器时,会出现此错误: 无法识别的选择器已发送到实例, 如果您在同一个班级没打错电话
var orderViewCard = OrderVC()
let tapGestureRecognizer = UITapGestureRecognizer(target: self,action: #selector(orderViewCard.handleCardTap(recognzier:)))
orderViewCard.handleArea.addGestureRecognizer(tapGestureRecognizer)
在OrderVC中:
@objc
func handleCardTap(recognzier:UITapGestureRecognizer) {
switch recognzier.state {
case .ended:
animateTransitionIfNeeded(state: nextState,duration: 0.9)
default:
break
}
}
解决方法
您需要做的是相应地选择目标
var orderViewCard = OrderVC()
let tapGestureRecognizer = UITapGestureRecognizer(target: orderViewCard,action: #selector(orderViewCard.handleCardTap))
orderViewCard.handleArea.addGestureRecognizer(tapGestureRecognizer)
