iOS + appium java客戶端：長按TouchAction不起作用？

Question

我想在本機iOS應用程序中自動化長按觸摸操作。

方法1：模擬長按在左上角沒有工作。

new TouchAction(driver).longPress(0,0).perform() Appium日誌沒有顯示錯誤：

方法2：執行JavaScript來模擬長按

((IOSDriver)driver).executeScript("mobile: longClick", ImmutableMap.of("x", 5, "y", 5));

Appium日誌例外如下：

TypeError: cb is not a function

Answer 1

將new TouchAction(driver).longPress(0,0).perform()更改爲

TouchAction action = new TouchAction(driver).longPress(0,0).release(); 

action.perform(); 

確保您擁有正確的座標。

Answer 2

您必須將2個參數傳遞給longPress（）方法。它們是你想要保存的元素（下面的代碼中的元素）和時間（2000毫秒）它需要保存多少時間。

MobileElement element = driver.findElementByClassName("xxx"); 
new TouchAction(driver).longPress(element, 2000).perform();
