PFUser (「所有者」) へのポインターを含む PFObject を配布しようとしています。
これが私のフェッチコードです:
public func collectHashTags(#sender:UIViewController, withinGeoCoordinate geoPoint:PFGeoPoint) {
var query = PFQuery(className:"Tag")
query.includeKey("owner") //...note: this doesn't give me the owner object.
// query.whereKey("lastGeo", nearGeoPoint:geoPoint, withinKilometers:2)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
let tagArray = query.findObjects() as [PFObject]
if tagArray.count > 0 {
for x in 0...(tagArray.count - 1) {
disseminateTags(tag:tagArray[x]) // ...load global Tag Array.
}
} else {
showAlert(sender, withTitle:"No Data", withMessage:"The HashTag file is empty.")
}
});
}
以下は、取得したいデータを持つ PFObject である「タグ」です。
private func disseminateTags(#tag:PFObject) {
let owner:PFUser = tag[gParseOwner] as PFUser
let parseID = tag.objectId as String
let displayName = tag[gParseDisplayName] as String
let description = tag[gParseDescription] as String
let radius = tag[gParseRadius] as CGFloat
let tagPublicFlag = tag[gParsePublic] as Bool
let startTime = tag[gParseStartTime] as NSDate
let endTime = tag[gParseEndTime] as NSDate
let media = tag[gParseMedia]? as [Int]
let startTimeString:String = startTime.toString()
let endTimeString:String = endTime.toString()
// Create the local hashTag object:
let myTag = hashTag(parseID: parseID, name: displayName, havingDescription: description, owner: owner)
myTag.radius = radius
myTag.publicFlag = tagPublicFlag
myTag.startTimeStamp = startTimeString
myTag.endTimeStamp = endTimeString
gTagArray.append(myTag)
}
ご覧のとおり、「タグ」にはデータがあります。PFUser オブジェクトである「所有者」を広めたい:
(lldb) po tag
<Tag: 0x7fac1f91c950, objectId: 5J1dNXUdaM, localId: (null)> {
Media = (
3,
2,
1
);
accessPemission = 1;
description = "Hashbrown Potatoes";
displayName = Smirf123;
endTime = "2104-12-17 20:20:00 +0000";
geoPoint = "<PFGeoPoint: 0x7fac1f99a990, latitude: 40.000000, longitude: -30.000000>";
owner = "<PFUser: 0x7fac1f993370, objectId: hk7zYRK4xB>";
public = 1;
radius = 2000;
startTime = "2104-12-15 20:20:00 +0000";
}
しかし、私は問題に直面しています。どうやら「所有者」を取得しました (オブジェクト ID に注意してください。上記を参照してください) が、デバッガーでそれを確認できません。
2 回目の試行:
'includeKey("owner") を使用しても役に立ちませんでした。だから私はそれをコメントアウトして、「所有者」属性が「タグ」クラスの兄弟に含まれるようにしました。
次に、所有者(id) フィールドでクエリを実行しようとしました(参照: https://www.parse.com/docs/ios_guide#queries/iOS ):
public func collectHashTags(#sender:UIViewController, withinGeoCoordinate geoPoint:PFGeoPoint) {
var query = PFQuery(className:"Tag")
// query.includeKey("owner")
// query.whereKey("lastGeo", nearGeoPoint:geoPoint, withinKilometers:2)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
let tagArray = query.findObjects() as [PFObject]
if tagArray.count > 0 {
for x in 0...(tagArray.count - 1) {
disseminateTags(tag:tagArray[x]) // ...load global Tag Array.
}
} else {
showAlert(sender, withTitle:"No Data", withMessage:"The HashTag file is empty.")
}
});
}
private func disseminateTags(#tag:PFObject) {
let owner = tag[gParseOwner] as PFUser
owner.fetchIfNeededInBackgroundWithBlock {
(object: PFObject!, error: NSError!) -> Void in
if error != nil {
println("Error: \(error)")
} else {
println("Fetched Owner: \(object)")
}
}
}
今回は、NSError に次のフラグが付けられました。
...Error: object not found for get (Code: 101, Version: 1.5.0)
...Error: object not found for get (Code: 101, Version: 1.5.0)
...Error: object not found for get (Code: 101, Version: 1.5.0)
...Error: object not found for get (Code: 101, Version: 1.5.0)
Error: Error Domain=Parse Code=101 "The operation couldn’t be completed. (Parse error 101.)" UserInfo=0x7ff9d260af40 {error=object not found for get, code=101}
Error: Error Domain=Parse Code=101 "The operation couldn’t be completed. (Parse error 101.)" UserInfo=0x7ff9d410ee80 {error=object not found for get, code=101}

Error: Error Domain=Parse Code=101 "The operation couldn’t be completed. (Parse error 101.)" UserInfo=0x7ff9d41082a0 {error=object not found for get, code=101}
3 回目の試行(後続の fetchIfNeeded() を使用):
public func collectHashTags(#sender:UIViewController, withinGeoCoordinate geoPoint:PFGeoPoint) {
var query = PFQuery(className:"Tag")
// query.whereKey("lastGeo", nearGeoPoint:geoPoint, withinKilometers:2)
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), {
let tagArray = query.findObjects() as [PFObject]?
if tagArray != nil {
let myTag = tagArray![0]
println("***myTag: \(myTag)")
let myName = myTag["displayName"] as String
println("displayName: \(myName)")
let myOwner = myTag["owner"] as PFUser
myOwner.fetchIfNeeded()
println("**** myOwner: \(myOwner)")
}
});
}
出力：
***myTag: <Tag: 0x7fa5d87e8f70, objectId: 5J1dNXUdaM, localId: (null)> {
Media = (
3,
2,
1
);
accessPemission = 1;
description = "Hashbrown Potatoes";
displayName = Smirf123;
endTime = "2104-12-17 20:20:00 +0000";
geoPoint = "<PFGeoPoint: 0x7fa5de104770, latitude: 40.000000, longitude: -30.000000>";
owner = "<PFUser: 0x7fa5de108070, objectId: hk7zYRK4xB>";
public = 1;
radius = 2000;
startTime = "2104-12-15 20:20:00 +0000";
}
displayName: Smirf123
2014-12-14 15:09:12.004 Bliss2[4757:181319] Error: object not found for get (Code: 101, Version: 1.5.0)
**** myOwner: <PFUser: 0x7fa5de108070, objectId: hk7zYRK4xB, localId: (null)> {
}
私はここで迷っています。
ホスティング レコードを使用して PFUser ポインターを配布することは、それほど難しくありません。
「所有者」(PFUser) から (文字列と画像) 属性を取得/抽出するにはどうすればよいですか?
