## iOS 'mobile:': 屏幕滑動(swipe) XCTest框架支持獨特的動作操作如"mobile:scroll" 和 "mobile:swipe"。它們不如UIScrollable那么靈活但仍然有用。 更多信息參考[https://developer.apple.com/documentation/xctest/xcuielement]() 文檔中'Scrolling' 和 'Performing Gestures' 部分. 通常滑動(swipe)操作完成滑動的動作而滾動(scroll)操作只是嘗試更改可見視圖而已。 !注意! 滾動方向在滑動(swipe)命令和滾動(scroll)命令中是不同的 ```java /** * Performs screen scroll * * @param dir the direction of scroll * @version java-client: 7.3.0 **/ public void mobileScrollScreenIOS(Direction dir) { System.out.println("mobileScrollScreenIOS(): dir: '" + dir + "'"); // always log your actions // Animation default time: // - iOS: 200 ms // final value depends on your app and could be greater final int ANIMATION_TIME = 200; // ms final HashMap<String, String> scrollObject = new HashMap<String, String>(); switch (dir) { case DOWN: // from down to up (! differs from mobile:swipe) scrollObject.put("direction", "down"); break; case UP: // from up to down (! differs from mobile:swipe) scrollObject.put("direction", "up"); break; case LEFT: // from left to right (! differs from mobile:swipe) scrollObject.put("direction", "left"); break; case RIGHT: // from right to left (! differs from mobile:swipe) scrollObject.put("direction", "right"); break; default: throw new IllegalArgumentException("mobileScrollIOS(): dir: '" + dir + "' NOT supported"); } try { driver.executeScript("mobile:scroll", scrollObject); // swipe faster then scroll Thread.sleep(ANIMATION_TIME); // always allow swipe action to complete } catch (Exception e) { System.err.println("mobileScrollIOS(): FAILED\n" + e.getMessage()); return; } } /** * Performs screen swipe * * @param dir the direction of swipe * @version java-client: 7.3.0 **/ public void mobileSwipeScreenIOS(Direction dir) { System.out.println("mobileSwipeScreenIOS(): dir: '" + dir + "'"); // always log your actions // Animation default time: // - iOS: 200 ms // final value depends on your app and could be greater final int ANIMATION_TIME = 200; // ms final HashMap<String, String> scrollObject = new HashMap<String, String>(); switch (dir) { case DOWN: // from up to down (! differs from mobile:scroll) scrollObject.put("direction", "down"); break; case UP: // from down to up (! differs from mobile:scroll) scrollObject.put("direction", "up"); break; case LEFT: // from right to left (! differs from mobile:scroll) scrollObject.put("direction", "left"); break; case RIGHT: // from left to right (! differs from mobile:scroll) scrollObject.put("direction", "right"); break; default: throw new IllegalArgumentException("mobileSwipeScreenIOS(): dir: '" + dir + "' NOT supported"); } try { driver.executeScript("mobile:swipe", scrollObject); Thread.sleep(ANIMATION_TIME); // always allow swipe action to complete } catch (Exception e) { System.err.println("mobileSwipeScreenIOS(): FAILED\n" + e.getMessage()); return; } } ```
