Appium : Clear a field

Question

I have my login screen in app now. Each time the app is launched in screen the mobile number is pre filled with the older text.

I just want to know I have tried:

Answer 1

To avoid recent iOS 8.x errors I use the following (where by is an instance of By representing your textfield/textview):

    int stringLength = driver.findElement(by).getText().length();
    if (stringLength > 0) {
        driver.findElement(by).clear();
    }

If you try and call clear() against an already clear textfield I was tending to get errors in appium.
