Question

LIKE this image i need to get emi amount using slider

     let numberOfPayments = Double(lblTenureAmount.text!) ?? .zero
                let interestRate = Double(lblInterestAmount.text!) ?? .zero
                let rate = interestRate / 100 / 12
                let answer = loanAmount * rate / (1 - pow(1 + rate, -numberOfPayments))
                lblLoanEMI.text = Formatter.currency.string(for: answer)

我尝试过使用 Ui 按钮操作获取数据，但实际上我需要使用滑块

Answer 1

您可以使用滑块视图的以下操作

@IBAction func sliderValueChanged(_ sender: UISlider) {
    let currentValue = Int(sender.value)
        
    label.text = "(currentValue)"
}
