Code To Reproduce Issue [ Good To Have ]

@Test
public void testBuyBuy() throws  InterruptedException {
    Thread.sleep(3000);
    driver.findElementByName("买买买").click();
    Thread.sleep(5000);
    IOSTouchAction iosTouchAction = new IOSTouchAction(driver);
    Thread.sleep(3000);
    for(int i = 0; i < 10; i++){
        int startX = 100;
        int startY = 600;
        int endX = 0;
        int endY = -500;

iosTouchAction.press(startX,startY).waitAction(1000).moveTo(endX,endY).release().perform();
Thread.sleep(2000);
}
}

I assume this code is not exactly doing what it is supposed to do, but try to move IOSTouchAction instance creation into the loop.

[vjmaiky]

i would do it like this:

public void swipeUntillElement (String subject) {
	int retry = 0;
	while (retry < 20) {
		try {
			WebElement we = null;
			we = AppiumDriverInstance.getInstance().findElementById(subject);
			if (we.isDisplayed()) {
				break;
			}
		} catch (Throwable e) {
			swipe_DownWithTouch(); Here put your swipe
		}
		retry++;
	}
	}
}

[mykola-mokhnach]

@vjmaiky this code might be less ineffective from performance point of view in comparison to a native call.

There is mobile: scroll endpoint with name/predicate/toVisible arguments, which does the same task natively.

BTW, I would not ever recommend catching Throwable explicitly.

[vjmaiky]

it can be use NosuchelementException with getting text and compare with desired catch expression, etc. Regarding mobile:scroll i will give it a try even if i like more touch actions.

[mykola-mokhnach]

Catch WebDriverException and you'll never miss anything ;)

[yefankongge]

@mykola-mokhnach I do it what you said，create IOSTouchAction instance into loop，everything looks all right
