getFirstObject () NSNull * null = PFObject * pointer = PFObject * bigObject = bigObject = number bigObject = bool bigObject = string bigObject = date bigObject = array bigObject = dictionary // shows up as 'object' in the Data Browser bigObject = null // this value can only be saved to an existing key bigObject = pointer // shows up as Pointer M圜lassName in the Data Browser whereKey ( "category", equalTo : "development" ) // Query first object found if let object = try ? query. Lastly, to recieve a callback after deleting objects asyncronously use deleteAllInBackground:block: as demonstrated below. The same can be done while blocking the calling thread using deleteAll. Lastly, deleteEventually is a network conscious option that deletes when possible but does not guarantee a timeframe for the tasks completion.įor deleting multiple objects use the PFObject static function deleteAllInBackground to delete an array of objects asynchronously. If you want to block the calling thread, you can use the delete method. If you prefer to recieve a callback you can use the deleteInBackgroundWithBlock: or deleteInBackgroundWithTarget:selector: methods. For basic asynchronous deletion of a single object call the objects deleteInBackground function. There are a few ways to delete a PFObject. You will have to call save in between every different kind of array operation. Note that it is not currently possible to atomically add and remove items from an array in the same save using. addUniqueObjects ( from :, forKey : "skills" ) gameScore. This is an asynchronous method, with variations for using either blocks or callback methods: If the PFObject has been uploaded to the server, you can retrieve it with its objectId by using a PFQuery. Saving data to the cloud is fun, but it’s even more fun to get that data out again. Each of these fields is filled in by Parse Server, so they don’t exist on a PFObject until the first save operation has been completed. createdAt and updatedAt represent the time that each object was created or last modified and saved to the Parse Server. objectId is a unique identifier for each saved object. There are also a few fields you don’t need to specify that are provided and set by the system as a convenience. Your Parse app lazily creates this Class for you when it first encounters it. You didn’t have to configure or set up a new Class called GameScore before running this code. Implementing Business Logic in Cloud Code.Requires Authentication permission (requires parse-server >= 2.3.0).Customizing/Localizing String Resources.

First, you could check if the image is well-format, it need PNG format, 1024x1024 pt (1024x1024 px, and it need untick the Alpha channel.
