如何從cloudkit獲取所有記錄

Question

我無法讓我的應用程序獲取所有類型的記錄並將每個用戶記錄放入數組中。

這是保存記錄

func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) { 
    let id = CKRecordID(recordName: "01") 
    let locationRecord = CKRecord(recordType: "location", recordID: id) 
    locationRecord.setObject(location, forKey: "location") 
    let publicData = CKContainer.defaultContainer().publicCloudDatabase 
    publicData.saveRecord(locationRecord) { record, error in 
    //.. 
    } 
} 

Answer 1

你需要使用CKQuery與NSPredicate設置爲true代碼：

let predicate = NSPredicate(value: true) 

let query = CKQuery(recordType: "location", predicate: predicate) 

database?.performQuery(query, inZoneWithID: nil) { results, error in 
    //... 
} 

Answer 2

CKDatabase *publicDatabase = [[CKContainer defaultContainer]]; 

NSPredicate *predicate = [NSPredicate predicateWithValue:YES]; 

CKQuery *query = [[CKQuery alloc] initWithRecordType:@"Group_attributes"]; 

[publicDatabase performQuery:query inZoneWithID:nil:^(NSArray *results,error){ 

}];
