<view style="padding-bottom: {{safeBottom + 10}}px;"></view>

onLoad(options) {const { screenHeight, safeArea, windowHeight } = wx.getWindowInfo()let safeBottom = windowHeightif (safeArea?.bottom) {safeBottom = safeArea.bottom}safeBottom = screenHeight - safeBottomthis.setData({safeBottom})
}

方案二（推荐）

padding-bottom: constant(safe-area-inset-bottom); /* 兼容iOS < 11.2 */  
padding-bottom: env(safe-area-inset-bottom); /* 兼容iOS > 11.2 */
