Firebase查询数组

Question

有什么可以简化这个吗？

databaseRef.child("palettes").queryOrdered(byChild: "0").queryEqual(toValue: text).observeSingleEvent(of: .value, with: { (snapshot) in

    print (snapshot)

})

databaseRef.child("palettes").queryOrdered(byChild: "1").queryEqual(toValue: text).observeSingleEvent(of: .value, with: { (snapshot) in

    print (snapshot)

})

databaseRef.child("palettes").queryOrdered(byChild: "2").queryEqual(toValue: text).observeSingleEvent(of: .value, with: { (snapshot) in

    print (snapshot)

})

databaseRef.child("palettes").queryOrdered(byChild: "3").queryEqual(toValue: text).observeSingleEvent(of: .value, with: { (snapshot) in

    print (snapshot)

})

databaseRef.child("palettes").queryOrdered(byChild: "4").queryEqual(toValue: text).observeSingleEvent(of: .value, with: { (snapshot) in

    print (snapshot)

})

我希望查询并搜索类似的颜色十六进制代码，然后获取整个数组，以便我的数据库的排列必须如此：

试试这个： -

 FIRDatabase.database().reference().child("palletes").queryOrderedByKey().queryStarting(atValue: "0").queryEnding(atValue: "5").observeSingleEvent(of: .value, with: {(snap) in

    print(snap)

    })
