我的Parse类是Groups。
在那个类中,我有很多列,包括createdBy:String和GroupMembersList:Array
对于一行,我有以下值:
GroupMembersList = ["Arun", "Daniel", "Jo"]
现在我如何从我的快速代码中add
remove
和update
这个群组的成员?
到目前为止,我知道这一点:
var query:PFQuery = PFQuery(className: "Groups")
query.whereKey("CreatedBy", equalTo: "Arun")
答案 0 :(得分:1)
您可以向群组添加属性,并像使用常规数组一样处理它:
extension Group {
var membersList: [String] {
get {
if let x = self["GroupMembersList"] as? [String] { return x }
return []
}
set(val) {
self["GroupMembersList"] = val
}
}
}
修改:可以使用Parse(docs)创建自定义PFObject
子类:
class Group: PFObject, PFSubclassing {
static func parseClassName() -> String {
return "Group"
}
var membersList: [String] {
get {
if let x = self["GroupMembersList"] as? [String] { return x }
return []
}
set(val) {
self["GroupMembersList"] = val
}
}
}
在AppDelegete
之前Parse.setApplicationId
:
Group.registerSubclass()
之后你可以使用你的子类:
let group = Group(objectId: "<group_id>")
group.membersList = ["some", "members", "here"]
let first = group.membersList[0]
group.saveInBackgroundWithBlock { (success, error) in
if (success) {
// The object has been saved.
} else {
// There was a problem, check error.description
}
}
