Reactnative iOS 模拟器如何确认alert信息

我正在使用react native的alert .

我如何让排毒者按下alert 信息上的"注销"按钮？

我试着用await element(by.text('Log out')).tap();

但我得到了"多元素匹配"的错误.大概它找到了3个标签相同的元素.标签为"Log out"的原始按钮用于触发alert 消息、alert 消息标题和我希望解毒按下的alert 消息按钮.

Error Trace: [

    "Description" : "Multiple elements were matched: (
    "<UILabel:0x7fe7964db910; AX=Y; AX.label='Log out'; AX.frame={{41, 234}, {238, 20.5}}; AX.activationPoint={160, 244.25}; AX.traits='UIAccessibilityTraitStaticText'; AX.focused='N'; frame={{16, 20}, {238, 20.5}}; opaque; alpha=1; UIE=N; text='Log out'>",

). Please use selection matchers to narrow the selection down to single element.",

    "Function Name" : "-[GREYElementInteraction grey_errorForMultipleMatchingElements:withMatchedElementsIndexOutOfBounds:]",

  }
]

我想一种方法是使用.atIndex()，但这意味着每次发生变化时我都需要使用索引来确定正确的元素.

没有更好的方法来解决这个问题吗？

谢谢
