Appium - 無法看到內部視圖元素在一個標籤欄控制器

[語境]
Appium 1.6.5
的XCode 8.3.3
的iOS 10.3
的Python 2.7Appium - 無法看到內部視圖元素在一個標籤欄控制器

我正在與Appium試驗與從創建選項卡式應用程序的XCode模板創建的基本iOS應用程序。我的應用程序是從該模板創建的，該模板基本上具有預設了2個選項卡的選項卡欄控制器。每個選項卡顯示不同的視圖。每個視圖都有2個標籤，其上有一些文字。

[目標]
我想寫一個劇本Appium導航到一個特定的標籤，然後讀取一個標籤的文本。

[問題]
我能夠找到的元素最多（並且包括）對應於所選擇的標籤的圖。但是，我沒有看到那個視圖中的任何元素。

我試圖使用ID和XPATH的結果相同。

注意：我嘗試訪問的每個元素都啓用了輔助功能，並設置了輔助功能ID。我設置的每個輔助功能ID都是唯一的。

[問題]
如何使用Appium訪問有問題的標籤？甚至更好，我的觀點的任何元素？

視圖1是我的兩個觀點之一，你可以在上面的XML看，它似乎並沒有包含任何標籤的該視圖：

 
<XCUIElementTypeOther type="XCUIElementTypeOther" name="view1" enabled="true" visible="true" x="0" y="0" width="375" height="667"/>

[Python代碼]
這裏是我使用的代碼：

driver = webdriver.Remote(get_appium_server(), desired_capabilities=get_capabilities()) 
driver.find_element_by_id('view1')  # This works fine 
driver.find_element_by_id('view1label1') # The code fails here despite the fact that this accessibility ID exists for one of the labels underneath 'view1'

當我運行它，我得到以下錯誤：

Traceback (most recent call last): 
    File "/some_path/Appium.py", line 33, in <module> 
    mypythonappiumfunction() 
    File "/some_path/Appium.py", line 28, in mypythonappiumfunction
