Collection of iOS drop-in components to visualize progress

Using 0.5.0.

Steps to reproduce:

Display a progress overlay on device using the sample app. This is reproducible on iPhone and iPad, although it is usually more noticeable on iPad. The screen will briefly flicker with a buggy texture.

I think from your previous comments that this is related to the asynchronous blur texture rendering. This is likely related to #42

Hi, I just updated my app to iOS 8.1, and there are two separate issues I'm having with MRProgress. Perhaps they are related. The app often crashes with EXC_BAD_ACCESS when I show an MRProgressOverlayView, and the overlay view does not have its fancy white background when it happens to not crash. It is a bit random, and unfortunately I haven't been able to get a stack trace. When it does not crash, the only thing shown is the progress view's title and the blue [in]determinate circle.

Things of note: -I am showing the overlay view in viewDidLoad in [self view]. If I move it to viewDidAppear, it seems to work, but that is not optimal since then the user sees the screen before the loading view is shown! -I do have the fix from the iPad non-flickering branch "installed," but this was also happening before I installed it.

Thanks.

Hello Guys,

I got a issue over here. I have added a MRActivityIndicatorView and called the startAnimating method. The View is visible but its not rotating. It's just like this:

But if I touch the home button and go back to the App it starts the animation.

i use MRProgressOverlayView+AFNetworking! but in one tableviewcontroller, it always loading,can not stop! how can i do?!

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.tableView.contentInset = UIEdgeInsetsMake(-1.0f, 0.0f, 0.0f, 0.0);

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];
    AFHTTPRequestOperation *operation = [manager GET:[[NSString stringWithFormat:@"http://localhost:3000/api/teams/%@", self.team_id] stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding] parameters:nil success:^(AFHTTPRequestOperation *operation, id responseObject) {
        self.labelTeamName.text = responseObject[@"name"];
        self.teamSportCell.detailTextLabel.text = responseObject[@"sport"];
        self.teamAreaCell.detailTextLabel.text = responseObject[@"area"];
        self.teamMemberCell.detailTextLabel.text = [NSString stringWithFormat:@"%@个", responseObject[@"members_count"]];
        if ([responseObject[@"avatar"] isEqualToString:@"blank.png!80x80"]) {
            self.imageTeamAvatar.image = [UIImage imageNamed: @"avatar.png"];
        } else {
            NSURLRequest *imageRequest = [NSURLRequest requestWithURL:[NSURL URLWithString:[NSString stringWithFormat:@"%@", responseObject[@"avatar"]]]];
            [self.imageTeamAvatar setImageWithURLRequest:imageRequest placeholderImage:nil success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image) {
                self.imageTeamAvatar.image = image;
            } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error) {
                self.imageTeamAvatar.image = [UIImage imageNamed: @"avatar.png"];
            }];
        }
    } failure:^(AFHTTPRequestOperation *operation, NSError *error) {
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"异常提示" message:@"网络异常" delegate:self cancelButtonTitle:@"确定" otherButtonTitles: nil];
        [alert show];
    }];

    MRProgressOverlayView *overlayView = [MRProgressOverlayView showOverlayAddedTo:self.view animated:YES];
    [overlayView setModeAndProgressWithStateOfOperation:operation];
    [overlayView setStopBlockForOperation:operation];

    [self.tableView addHeaderWithTarget:self action:@selector(headerRereshing)];
}

Hello,

I am trying to launch example. But after pod install, I always get this error:

Fetching podspec for `MRProgress` from `.`

[!] Invalid `MRProgress.podspec` file: [!] A subspec can't require one of its parents specifications. Updating CocoaPods might fix the issue.

 #  from /Users/genimac/Downloads/MRProgress-master/Pods/Local Podspecs/MRProgress.podspec:66
 #  -------------------------------------------
 #        subspec spec_name do |subs|
 >          subs.dependency 'MRProgress/AFNetworking/Base'
 #          subs.dependency "MRProgress/#{spec_name}"
 #  -------------------------------------------

My version of CocoaPods is 0.33.1

Any help will be appreciated. Thanks in advance.

P.S. I also tried to change Local Podspecs file, but each time it is replaced by autogenerated one...

Uses UIVisualEffectView in combination with UIBlurEffect for the blur in MRProgressOverlayView.

• [x] Blocked by iOS 8 GM.
• [x] Blocked by rdar://18466755. (Specific to "classic" resolution on new phones.)

If using this component on an iPad, it is possible to cause the screen to flicker briefly while rotating the app. This is reproducible in the sample app. I am unsure if this happens in iPad apps - I have so far only tested this in iPhone apps running on an iPad. Perhaps the issue is related to rendering the blur texture?

Steps to reproduce:

• Load up the sample app on an iPad (or iPad Mini).
• Get once of the progress overlays to appear on screen.
• Rotate the device whilst it is visible.

Using version 0.4.3.

See the video for the glitch - it is quite subtle: https://drive.google.com/file/d/0B7hk_IdN2v-QUUFOcld6VGY2Y2JwYzViWlFxOTE1cy1RRzN3/edit?usp=sharing

I have noticed a bug/cosmetic issue with the white background of the progress overlay appearing after a delay, or occasionally not at all. This does not seem to happen in the simulator, but does on an iPhone 4S running 7.1 using the example app.

Using version 0.4.3.

Symptoms:

• With animations disabled, the overlay background does not seem to appear at the same time as the actual progress spinner itself. I have attached a video, although it is quite subtle to see the effect.
• This also is an issue when displaying the progress view with an animation. In some circumstances, the overlay view can appear, and be dismissed, before the background has actually appeared.

The background not appearing at all is difficult to reproduce consistently as it does not seem to be deterministic, however, you can see the delay of the background appearing every time by using the sample app (on device) and presenting an overlay view without the animation - observe that the white background appears noticeably after the spinner component.

Video: Unfortunately this isn't quite as clear as I would hoped. The best way to see is to skip through each frame invidually using Quicktime: https://drive.google.com/file/d/0B7hk_IdN2v-QYlQtSG5hdTBYOGFMWWNtZmVpeTR3Tm1kTm5V/edit?usp=sharing

Getting error that crashes app: 2015-01-24 16:50:04.563 Pickle[24864:6627769] -[UIImage mr_applyBlurWithRadius:tintColor:saturationDeltaFactor:maskImage:]: unrecognized selector sent to instance 0x7f8255323820

After calling: MRProgressOverlayView.showOverlayAddedTo(self.view.window, animated: true).

The progress view shows up fine, but it appears that as soon as it tries to make its background an opaque white it is crashing.

The offending line of code that Xcode is highlighting on the crash: image = [image mr_applyBlurWithRadius:30.0 tintColor:[UIColor colorWithWhite:0.97 alpha:0.82] saturationDeltaFactor:1.0 maskImage:nil]; Which is from the MRBlurView class.

If you change the Text Size to a smaller size for iOS Dynamic Type via Settings -> Display & Brightness -> Text Size, the MRProgressOverlayView's label appears to get cut off and not display the text properly.

Use case:

1. showing indeterminate progress in list at first controller
2. push second controller
3. animation is stopped when popped back to first controller

This fixes that behaviour

MRProgressHelper.h and MRBlurView.m call +[UIApplication sharedApplication], which is not available in App Extensions, meaning that MRProgress will not compile for extension targets.

MRProgress/src/Utils/MRProgressHelper.h:41:56: 'sharedApplication' is unavailable: not available on iOS (App Extension) - Use view controller based solutions where appropriate instead.

MRProgressOverlayView.showOverlayAdded(to: self.view, title: text, mode: .indeterminateSmallDefault, animated: true) i have added code to MRProgress and working fine but i need to change activity indicator colour from gray to orange. So, how can i do this? please help me.

Hi, I want to send the MRProgressView to the other viewController. I used it like this but it did not work.

FirstViewController.m

self.overlayView = [MRProgressOverlayView showOverlayAddedTo:self.navigationController.view animated:YES];        
self.overlayView.mode = MRProgressOverlayViewModeIndeterminateSmall;
self.overlayView.titleLabelText = @"";
[AppDelegate setOverlayView:self.overlayView]

AppDelegate.m

// showing overlay = nil
-(void)setOverlayView:(MRProgressOverlayView *)overlay{
  self.overlayView = overlay;
}

// I will get from here
-(MRProgressOverlayView *)getOverlayView{
   return self.overlayView;
}

SecondViewController.m

// call from here
[[AppDelegate getOverlayView] dismiss:YES];

But it always calls setOverlayView and says overlay = nil. why?

Hello, trying to use MRProgress with AVAssetExportSession in swift 2.2 I want to display the overlay according the the session.progress value (going from 0 to 1). It seems however that setting the progress to the overlay does nothing until the value is equal to 1. If i did something wrong in my code could someone point me to the good direction? Here is the related code :

if let exportSession = AVAssetExportSession(asset: urlAsset, presetName: Config.VIDEO_COMPRESSION_PRESET) { exportSession.outputURL = outputURL exportSession.outputFileType = AVFileTypeMPEG4 exportSession.shouldOptimizeForNetworkUse = true exportSession.timeRange = CMTimeRangeMake(kCMTimeZero, urlAsset.duration)

        exportSession.exportAsynchronouslyWithCompletionHandler { () -> Void in
            handler(session: exportSession)
        }
        dispatch_async(dispatch_get_main_queue(), { () -> Void in
            let overlayView = MRProgressOverlayView.showOverlayAddedTo(self.view, title: "Preparing", mode: .DeterminateCircular, animated: true)
            while exportSession.status == .Waiting || exportSession.status == .Exporting {
                print("Progress: \(exportSession.progress * 100.0)%., progress \(exportSession.progress)")
                overlayView.setProgress(exportSession.progress, animated: true)
            }
            overlayView.dismiss(true)
        })
    }

output example from my print : Progress: 2.62599%., progress 0.0285576

Or it can be due to the animation delay for the overlay to appear, not sure about that.

Hi guys,

First off, thanks for putting this really amazing looking library out there

Could someone please provide a solution as to how to implement this beautiful library in Swift

I can load the OverlayView but I can't figure out how to connect the progress

I am using Alamofire

In my post request

var progressFloat: Float = 0.0
...
                    upload.uploadProgress(closure: { //Get Progress
                        progress in

                        print(progress.fractionCompleted)

                       // cast value as float
                       progressFloat = Float(progress.fractionCompleted)
                        
                        // the initial overlay view gets loaded 
                        MRProgressOverlayView.showOverlayAdded(to: self.view, title: "Uploading", mode: MRProgressOverlayViewMode.determinateCircular, animated: true)
                        
                        // this is where I am stuck 
                        // setProgress is a child, but throws error:
//  'use of instance member 'setProgress' on type MRProgressOverlayView'; did you mean to use a value of type MRProgressOverlayView
                        MRProgressOverlayView.setProgress(progressFloat, true)

                      // MRProgressView.setProgress doesn't work either 

I am also getting the error 
/Pods/MRProgress/src/Components/MRProgressOverlayView.m:815
2017-01-23 16:23:32.207 MyProject[5844:139083] *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Mode must support setProgress:animated:, but doesnot!'

                        if progress.fractionCompleted == 1 {
                            print("Completed")
 
                            // this is also throwing an error 
                            MRProgressOverlayView.dismiss(self)
                        }
                    })
