When I\'m changing for example a bool in the Parse backend I can not retrieve this value in my iOS app. Please see the following screenshot where the first bool of the user obje

When you have pointers you can not use fetch. this is the best way:

 PFQuery *userQuery = [PFUser query];
    [userQuery includeKey:@"addresses"];
    [userQuery includeKey:@"cards"];
    [userQuery whereKey:@"objectId" equalTo:[PFUser currentUser].objectId];
    [userQuery getFirstObjectInBackgroundWithBlock:^(PFObject * _Nullable object, NSError * _Nullable error) {
}];

Examples in Swift:

First and foremost, please have a look at isDataAvailable and isDirty.

var user = PFUser.currentUser()!

// Gets whether the PFObject has been fetched.
// isDataAvailable: true if the PFObject is new or has been fetched or refreshed, otherwise false.
user.isDataAvailable()

// Gets whether any key-value pair in this object (or its children) has been added/updated/removed and not saved yet. 
// Returns whether this object has been altered and not saved yet.
user.isDirty()

Also it is probably better/more efficient to use fetchIfNeeded, fetchIfNeededInBackground, or fetchIfNeededInBackgroundWithBlock: "since they will use the local cache when available."

// Synchronously fetches the PFObject data from the server if isDataAvailable is false.
user.fetchIfNeeded()

// Fetches the PFObject data asynchronously if isDataAvailable is false, then sets it as a result for the task.    
user.fetchIfNeededInBackground()

// Fetches the PFObject data asynchronously if isDataAvailable is false, then calls the callback block.        
user.fetchIfNeededInBackgroundWithBlock({ 
            (object: PFObject?, error: NSError?) -> Void in
    // Code here         
})

Otherwise you can also use fetch, fetchInBackground, fetchInBackgroundWithBlock if you do not need to use the local cache.

// Synchronously fetches the PFObject with the current data from the server.
user.fetch()
            
// Fetches the PFObject asynchronously and sets it as a result for the task.
user.fetchInBackground()
            
// Fetches the PFObject asynchronously and executes the given callback block.
user.fetchInBackgroundWithBlock({
               (object: PFObject?, error: NSError?) -> Void in
     // Code here
})

Answer 3

After you've made changes to your user's Parse table, call

[[PFUser currentUser] fetch]; //synchronous

or

[[PFUser currentUser] fetchInBackground]; //asynchronous

or

[[PFUser currentUser] fetchInBackgroundWithBlock:^(PFObject *object, NSError *error) { //asynchronous with completion block

before

[[PFUser currentUser] objectForKey:@"is_pro"]

to get an updated copy of your [PFUser currentUser] object.

Note: refresh and refreshInBackgroundWithBlock: are now deprecated and have been replaced with fetch and fetchInBackgroundWithBlock:

Update:

As Ryan Kreager pointed out in the comments, it's probably better/more efficient to use fetchIfNeeded, fetchIfNeededInBackground, or fetchIfNeededInBackgroundWithBlock: "since they will use the local cache when available."
