No, there is no virus on your iPhone. You were a victim of phishing or a scam. These scammers are either after your Apple ID and Password or they want you to subscribe to something that you did not intend to. The idea behind both of the above is to steal money from you, as you already know.
You do not have to worry about a virus (Unless your iPhone is Jailbroken) however I recommend that you change the password to your Apple ID as shown HERE. This is just to be double safe.
If you go to Calendars at the bottom of the screen there, do you see a calendar listed that matches the color of these events? If you see a strange calendar there under Other or Subscribed, can you uncheck it? Then you may want to check, it seems they get will add a strange mail account. Go to Settings>Passwords & Accounts and see if you find a strange email account there. It may be where the calendar syncing is coming from. Delete the account from there. You will also want to check Settings>General>Profiles, and see if there is anything unusual listed there.
That is a Rogue Calendar account. Go to Settings-->>Passwords & Accounts and under Accounts see if an unknown calendar account is listed. If it is then tap on it and then Delete account.
same here and then my phone started lagging. I posted on my instagram that i was so hyped to watch kissing booth 2 at 3am sharp and my posts were lagging but also fast at times and at 3am sharp i open netflix on my phone and it says the network connection isn't working but everyone in my household's devices are working especially my computer. Now i am stuck watching Netflix on my computer.
For these reasons, views retrieve their data from Model objects, which act as intermediaries between the view and the Data Source. Models abstract over Data Sources and provide several important services:
Models use a DataSource to retrieve data from the JSON Graph. Falcor ships with HttpDataSource, an implementation of the DataSource interface which proxies requests to another DataSource running on an HTTP server (usually a falcor Router).
There is one very important difference between working with a JSON object directly and working with that same JSON object through a Falcor Model: you can only retrieve value types from a Model.
Models force developers to be explicit about which value types they would like to retrieve in order to maximize the likelihood that server requests will have stable performance over time. Rather than allow you to retrieve an entire Object, Models force you to be explicit and retrieve only those values needed in a given scenario. Similarly, when displaying an Array of items, Models do not allow you to retrieve the entire Array upfront. Instead you must request the first visible page of an Array, and follow up with additional page requests as the user scrolls. This allows your client code to control performance boundaries, based on the amount of data actually used in the view, as opposed to being susceptible to unexpected increases in the total amount of data available.
The main advantage of using an asynchronous API is that you can code against JSON data the same way regardless of whether the data is local or remote. This makes it very easy to begin coding your application against mocked data at first, and then work against server data later on without changing client code.
In the example above, we retrieve the name of the first TODO from a JSON Object.In the code sample below, the data has been moved to the cloud but the client code that retrieves the data remains the same:
While Models retrieve information from DataSources in JSON Graph format, they emit information in JSON format. You can retrieve JSON data from a Model by using its get method. In the following example, we will retrieve the names of the first two tasks in a TODOs list from a Model.
The Model merges the response from the DataSource into its internal JSON Graph cache, and creates a JSON format copy of the response by replacing all JSON Graph Reference objects with real object references. The resulting JSON object is returned to the caller in an envelope, and printed to the console:
To allow for transactional operations, JSON Graph objects can contain functions just like JavaScript objects. Functions are considered JSON Graph objects, which means they cannot be retrieved from, nor set into, a DataSource. Rather, functions can only be invoked using the call method.
Typically, returnValuePaths are used when the function creates a new object and returns a reference to that object. The refPaths can be passed to the call method in order to allow fields to be retrieved from the newly-generated object without the need for a subsequent get operation.
In the event that any of the values returned from the function are JSON Graph References, the DataSource will append each of the refPaths to each Reference path and evaluate the concatenated paths. The resulting values are added to the JSON Graph response by the DataSource.
Why is this necessary? Unlike get and set operations, there is no way for the Model to predict what values will be returned from a function call. By providing the Model with an array of paths to the values within the JSONGraph object, the function allows the Model to merge the response into its local cache without resorting to reflection.
Instead of returning the task data in the response, including a reference to the task allows the caller to decide what values from the newly-created task should be retrieved by specifying the refPaths argument. Recall that the following paths were passed as the refPaths argument:
Notice that the response above now contains the name and done fields of the newly added task object. Using the refPaths argument, we are able to retrieve values from object references returned from the function.
Now that the function has run successfully, and the values have been retrieved from the references in the response, the extraPaths paths are retrieved. Recall that, for our implementation, we requested the following relative path from the this object:
When dealing with shared mutable data, it is important to avoid race conditions. For example, what if two different users are modifying objects in a list at the same time? How do we ensure that operations are applied to the right objects, even though objects may shift around in the list between being displayed to the user and being modified by the user?
Falcor provides the deref method to allow you to refer to objects by their identity rather than their location in the graph. When you dereference a Falcor Model against an object you previously retrieved from the Model, you create a new Model bound to that object. All future operations performed on this Model will be performed on the dereferenced object in the graph, whether it be get, set, or call operations.
To display the information, we can create a list view which accepts a Model and displays a list of summarized information about each title. When the user clicks on a title within the list, we will open the detail view and display additional information about the title. This begs the question of how the List view will send the selected title to the detail view.
This is an anti-pattern because the path contains the index in the list where the title is located, and this item may shift in the list between the time the object is displayed and the user drills down and selects it.
In this example, when a user clicks on a title, we dereference a Model against the title object we retrieved earlier. We pass the dereferenced Model to the Detail view which can use it to retrieve more information from the title.
Operations performed on the dereferenced Model will always be applied to the same object, no matter where the object is moved within the graph. Furthermore code can interact with the object without any knowledge of its location within the graph.
Note the $__path added to the JSON response. When you dereference an object within a Falcor response, the new Model internally stores this path. Note that you should not use these metadata properties directly, as the specific property name may change over time and is an implementation detail. Rather you should use the public deref method instead.
Dereferenced models can be passed as the argument to a function invoked with call. This approach allows you to pass an object to a function by identity, rather than a path to a volatile location within the graph.
In addition to being able to work with JSON documents, Models can also operate on JSON Graph documents. JSON Graph is a convention for modeling graph information in JSON. JSON Graph documents extend JSON with References. References can be used anywhere within a JSON object to refer to a value elsewhere within the same JSON object. This removes the need to duplicate objects when serializing a graph into a hierarchical JSON object.
If we examine the JSON object after this change, we will notice that the change has not been propagated to all of the copies of the task. Because the same task also appears in the prerequisites array of task 2692, its done value remains false.
When application servers send subsets of the graph across the network as JSON, they typically use the duplicate and identify strategy. If the same object appears more than once in the JSON response, the application server includes a unique ID within the object. The application client is expected to use the IDs to determine if the two copies of an object represent the same entity. This code must often be specialized for each new type of message that comes back from the server. Failing to de-dupe objects can lead to stale data being displayed to the user.
