Why?

I needed to display status/activity views that still allow user interaction in the rest of the view. Unlike what many other projects do, I needed to display the status view per view (or view controller), rather than globally throughout the app. I didn't find any projects that fulfilled my needs, so I authored this project.

What?

JCActivityBar allows to add a view to any view controller that handles displaying status/activity messages.

Example Code?

A working sample iOS Xcode project is available in the Demo directory.

Usage?

#import "JCActivityBar.h"

- (void) viewDidLoad {
  if (!self.activityBar) {
    self.activityBar = [[JCActivityBar alloc] init];
    [self.activityBar positionInBottomOfView:self.view withBottomOffset:20.0];
  }
  [self.view addSubview:self.activityBar];
}

- (IBAction) displayMessageButtonTapped:(UIButton*)sender {
  [self.activityBar displayActivityWithMessage:@"Activity description."];
  float delayInSeconds = self.secondsDelayStepper.value;
  dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
  dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
    [self.activityBar finishWithSuccess:@"Finished!"];
    // Or the following for an error:
    // [self.activityBar finishWithError:@"Error."];
  });
}

Installation?

This project includes a podspec for usage with CocoaPods. Simply add

pod 'JCActivityBar'

to your Podfile and run pod install.

Alternately, you can add all of the files contained in this project's Library directory to your Xcode project. If your project does not use ARC, you will need to enable ARC on these files. You can enable ARC per-file by adding the -fobjc-arc flag, as described on a common StackOverflow question.

Acknowledgements

This project was inspired by Zac Altman's ZAActivityBar project which can be found at https://github.com/zacaltman/ZAActivityBar/. Unlike Zac's project, I needed my activity bar to be linked to specific views (for examnple, per view controller) rather than global for the app.
