小程序判断当前系统是安卓或是ios

看到官方组件里的是判断是否为安卓：

  lifetimes: {
    attached() {
      const rect = wx.getMenuButtonBoundingClientRect()
      const platform = (wx.getDeviceInfo() || wx.getSystemInfoSync()).platform
      const isAndroid = platform === 'android'
      const isDevtools = platform === 'devtools'
      const { windowWidth, safeArea: { top = 0, bottom = 0 } = {} } = wx.getWindowInfo() || wx.getSystemInfoSync()
      this.setData({
        ios: !isAndroid,
        innerPaddingRight: `padding-right: ${windowWidth - rect.left}px`,
        leftWidth: `width: ${windowWidth - rect.left}px`,
        safeAreaTop: isDevtools || isAndroid ? `height: calc(var(--height) + ${top}px); padding-top: ${top}px` : ``
      })
    },
  },

就按官方的写了，之前查的怕以后找不到，暂时先留个底。

const windowInfo = wx.getWindowInfo();
const deviceInfo = wx.getDeviceInfo();
const isIOS = deviceInfo.platform === 'ios' || deviceInfo.system.toLowerCase().includes('ios');
