Closing animation is very choppy about cwstatusbarnotification HOT 8 CLOSED

I can't quite see what's going on with that gif, as the gif itself seems somewhat choppy, but do you experience the same issue with the demo app? If not, the first thing I might try is handling the notification on the main queue in your app.

from cwstatusbarnotification.

This is my set up :

    self.statusBarNotification = [CWStatusBarNotification new];
    self.statusBarNotification.notificationLabelBackgroundColor = [UIColor colorWithRed:212.0/255.0 green:212.0/255.0 blue:212.0/255.0 alpha:1.0];
    self.statusBarNotification.notificationLabelTextColor = [UIColor blackColor];
    [self.statusBarNotification displayNotificationWithMessage:@"Fetching stations ..." completion:nil];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    [manager GET:@"http://rpi.athwani.net:8843/stations" parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {

        self.stationsDisctionary = (NSDictionary *)responseObject;
        [[NSNotificationCenter defaultCenter] postNotificationName:gotStations object:nil userInfo:nil];

        dispatch_async(dispatch_get_main_queue(), ^{
            [self.statusBarNotification dismissNotification];
        });


    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        NSLog(@"Error: %@", error);
    }];

I've uploaded a video of the problem here :

The sample project seems to be working fine ....

This probably isn't your issue, but AFNetworking success blocks are guaranteed to be called on the main thread, so the dispatch to the main queue is unnecessary.

Moved the dismiss call outside the dispatch to main queue, and still no luck. The closing animation is still choppy :(

Is the other stuff before the AFNetworking call on the main thread too?

It's actually in a singleton which handles all the downloads. The singleton is called from the main thread for sure.

Sorry that I haven't gotten around to this; I've been busy with school.

Anyhow, I tried to recreate your situation like this:

self.notification = [CWStatusBarNotification new];
self.notification.notificationLabelBackgroundColor = [UIColor colorWithRed:212.0/255.0 green:212.0/255.0 blue:212.0/255.0 alpha:1.0];
self.notification.notificationLabelTextColor = [UIColor blackColor];
[self.notification displayNotificationWithMessage:@"Fetching stations ..." completion:nil];

dispatch_after(dispatch_time(DISPATCH_TIME_NOW, (int64_t)(2.0 * NSEC_PER_SEC)), dispatch_get_main_queue(), ^{  
    [self.notification dismissNotification];
});

However, everything looked fine on my end.

Based on the video you provided, I made a better quality gif.

Here are the exploded frames for the closing:

It looks like there is another black bar that is covering up the notification as it is being dismissed.

I took another look at the starting animation:

It looks like there is also an issue with the start, as at the beginning, the status bar area is black and the status bar is fading back in. The way the library works is by taking a screenshot of the status bar before displaying the notification, so if this area is black or in some other state of transition before the notification is displayed, this will obviously cause issues.

Are you doing anything else with the status bar before displaying the notification? That would explain why you were having this issue.

I figured out the issue .... I was indirectly calling this from the app delegate ... hence the choppy animation ...
