问题描述
我希望在cloudkit中更新用户的位置,但是我的代码每次都只保存一个新记录。如何修改现有记录或将其替换为新记录?
I want the users' location to be updated in cloudkit but my code just save a new record every time. How can the existing record be modified or replaced by the new one?
func locationManager(manager: CLLocationManager, didUpdateLocations locations: [CLLocation])
{
let location = locations.last
let center = CLLocationCoordinate2D(latitude: location!.coordinate.latitude, longitude: location!.coordinate.longitude)
let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
self.mapView.setRegion(region, animated: true)
self.locationManager.stopUpdatingLocation()
locationRecord.setObject(location, forKey: "location")
let publicData = CKContainer.defaultContainer().publicCloudDatabase
publicData.saveRecord(locationRecord) { record, error in
}
if error == nil
{
print("Location saved")
self.loc1 = location!
}
}
推荐答案
到修改记录,您需要提取原始记录-更新详细信息,然后保存记录。
To Modify a record, you need to pull in your orignal record - update the details and then save the record.
我可以通过缓存对原始recordID的引用来做到这一点,例如
I would do this by caching a reference to the original recordID eg
var locationRecordforUser = (whatever your CKrecord was when you created it)
然后在上面的位置方法中,只需抓住它,进行更改并执行保存
then in your location method above, just grab it, make changes and perform save
record.setValue(locationbits, forKey: locationField)
self. publicData.saveRecord(record, completionHandler: { (savedRecord, error) in
dispatch_async(dispatch_get_main_queue()) {
completion(savedRecord, error)
}
})
