我有一堆数据我正在保存为一个pfobject进行解析，我将它们保存在单独的字段中。我的问题是，最后我希望能够搜索这些数据，访问所有字段，但这是非常低效的。有人建议我把字段保存在一个数组中。但我不知道该怎么做，我到处寻找。如何在一个数组中保存PriceText和ViewsText的底部两个字段并保存该字符串数组。下面是代码。
let table = PFObject(className: "Example")
table["Price"] = PriceText
table["Views"] = ViewsText
table.saveInBackground { (success:Bool, error:Error?) -> Void in
if success {
}else{
}
}
var query : PFQuery<PFObject>!
query.order(byDescending: "createdAt")
let fiel1 = PFQuery(className: "Real Estate")
field1.whereKey("field one", contains: search)
let field2 = PFQuery(className: "Real Estate")
field2.whereKey("field two", contains: search)
let field3 = PFQuery(className: "Real Estate")
field3.whereKey("field three", contains: search)
let field4 = PFQuery(className: "Real Estate")
field3.whereKey("field four", contains: search)
let field5 = PFQuery(className: "Real Estate")
field5.whereKey("field 5", contains: search)
let field6 = PFQuery(className: "Real Estate")
field6.whereKey("field 6", contains: search)
let field7 = PFQuery(className: "Real Estate")
field7.whereKey("field 7", contains: search)
let field8 = PFQuery(className: "Real Estate")
field8.whereKey("field 8", contains: search)
let field9 = PFQuery(className: "Real Estate")
field9.whereKey("field 9", contains: search)
let field10 = PFQuery(className: "Real Estate")
field10.whereKey("field 10", contains: search)
let field11 = PFQuery(className: "Real Estate")
field11.whereKey("field 11", contains: search)
let field12 = PFQuery(className: "Real Estate")
field12.whereKey("field 12", contains: search)
let field13 = PFQuery(className: "Real Estate")
field13.whereKey("field 13", contains: search)
let field14 = PFQuery(className: "Real Estate")
field14.whereKey("field 14", contains: search)
let field15 = PFQuery(className: "Real Estate")
field15.whereKey("field 15", contains: search)
let field16 = PFQuery(className: "Real Estate")
field16.whereKey("field 16", contains: search)
let field17 = PFQuery(className: "Real Estate")
field17.whereKey("field 17", contains: search)
let field18 = PFQuery(className: "Real Estate")
field18.whereKey("field 18", contains: search)
let field19 = PFQuery(className: "Real Estate")
field19.whereKey("field 19", contains: search)
let field20 = PFQuery(className: "Real Estate")
field20.whereKey("field 20", contains: search)
let field21 = PFQuery(className: "Real Estate")
field21.whereKey("field 21", contains: search)
let field22 = PFQuery(className: "Real Estate")
field22.whereKey("field 22", contains: search)
let field23 = PFQuery(className: "Real Estate")
field23.whereKey("field 23", contains: search)
let field24 = PFQuery(className: "Real Estate")
field24.whereKey("field 24", contains: search)
let field25 = PFQuery(className: "Real Estate")
field25.whereKey("field 25", contains: search)
let field26 = PFQuery(className: "Real Estate")
field26.whereKey("field 26", contains: search)
let field27 = PFQuery(className: "Real Estate")
field27.whereKey("field 27", contains: search)
let field28 = PFQuery(className: "Real Estate")
field28.whereKey("field 28", contains: search)
let field29 = PFQuery(className: "Real Estate")
field29.whereKey("field 29", contains: search)
let field30 = PFQuery(className: "Real Estate")
field30.whereKey("field 30", contains: search)
let objectId = PFQuery(className: "Real Estate")
objectId.whereKey("objectId", contains: search)
query = PFQuery.orQuery(withSubqueries: [field1, field2, field3, field4, field5, field6, field7, field8, field9, field10, field11, field12, field13, field14, field15, field16, field17, field18, field19, field20, field21, field22, field23, field24, field25, field26, field27, field28, field29, field30, objectId])
