Indicator not dismissing

[keithlee]

Issue happens when:

1. Load a viewcontroller, query something in the background (e.g. Parse query.findObjectsInBackground)
2. In query.findObjectsInBackground callback (dismiss Progress)
3. Indicator still there

Note: Only occurs on first time FTIndicator is loaded. Hacked around issue by callign showprogress and then dismissprogress in AppDelegate before any views can be loaded

Happens when loading a new view controller. I believe the indicator hasn't had time to load before calling my dismiss, which causes the issue. Showing and dismissing progress occurs on main thread

I think maybe when query done callback, you should call dispatch_get_main_queue().

I tried that, still didn't work. Confirmed that showing/dismissing is on main queue. Its something about the initial initialization of the FTIndicator thats having issues

I tried the following methods, works fine. Just upload some code, try run the demo and click the + button on the up-left. Maybe let me see some of your code to help me understand more about this issue. Thanks.

• (void)viewDidLoad {
  [super viewDidLoad];

  [FTProgressIndicator showProgressWithmessage:@"Something is happening..."];

  dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{

    for (NSInteger i = 0; i < 1000; i++) {
        NSLog(@"print out %ld",i);
    }
    
    sleep(3);
    
    dispatch_async(dispatch_get_main_queue(), ^{
        [FTProgressIndicator dismiss];
    });
  

  });

}

This is the code snippet where the problem is occurring. It only occurs the first time I see FTIndicator and only when I’m switching to or loading a new view controller. After that everything works fine. I can clear the indicator that won’t go away, by performing an action that shows the indicator again. When I debug, the breakpoint hits dismissProgress callback before the indicator is actually shown. private func fetchObjects(){ FTIndicator.showProgressWithmessage("") query.findObjectsInBackground { (objects: [PFObject]?, error: Error?) in FTIndicator.dismissProgress()

Make sure it is dispatch_async. other than that, I can't find any other way to solves this for now.

I tried dispatch_async but issue still occurs
