 let array = [TRRateHeardModel(title: "王木木"),                     TRRateHeardModel(title: "王木木"),                     TRRateHeardModel(title: "王木木")]        self.heardView = TRRateHeardView(array: array)        self.view.addSubview(heardView)        self.heardView.snp.makeConstraints {            $0.edges.equalToSuperview()        }
