小熊翻译App(macOS和iOS)提醒您:
func setupNav() {
self.navigationItem.rightBarButtonItem = UIBarButtonItem(image: UIImage(named:"shaixuan_icon"), style: .plain, target:self,action:#selector(rightNavBtnAction))
}
@objc func rightNavBtnAction() {
print("价格筛选")
let priceContainerView = UIView.init(frame: CGRect(x: 0, y: 0, width: SWSize.screenWidth, height: SWSize.screenHeight))
// 关键代码
self.tabBarController?.view.addSubview(priceContainerView)
priceContainerView.backgroundColor = UIColor.init(white: 0, alpha: 0.3)
}
