How to create custom UIActivity in iOS?

Question

How to create custom UIActivity in iOS?

The reason I want this is to add the “Browse for apps” button in one of my apps, which brings the user to the browse section of the App Store. How to create such a custom UIActivity ?

Answer 1

First create the files. I chose the name Activity ActivityCustomActivity

Make ActivityViewCustomActivity.h as follows:

 #import <UIKit/UIKit.h> @interface ActivityViewCustomActivity : UIActivity @end 

Make ActivityViewCustomActivity.m look like this:

 #import "ActivityViewCustomActivity.h" @implementation ActivityViewCustomActivity - (NSString *)activityType { return @"yourappname.Review.App"; } - (NSString *)activityTitle { return @"Review App"; } - (UIImage *)activityImage { // Note: These images need to have a transparent background and I recommend these sizes: // iPadShare@2x should be 126 px, iPadShare should be 53 px, iPhoneShare@2x should be 100 // px, and iPhoneShare should be 50 px. I found these sizes to work for what I was making. if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { return [UIImage imageNamed:@"iPadShare.png"]; } else { return [UIImage imageNamed:@"iPhoneShare.png"]; } } - (BOOL)canPerformWithActivityItems:(NSArray *)activityItems { NSLog(@"%s", __FUNCTION__); return YES; } - (void)prepareWithActivityItems:(NSArray *)activityItems { NSLog(@"%s",__FUNCTION__); } - (UIViewController *)activityViewController { NSLog(@"%s",__FUNCTION__); return nil; } - (void)performActivity { // This is where you can do anything you want, and is the whole reason for creating a custom // UIActivity [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"itms-apps://ax.itunes.apple.com/WebObjects/MZStore.woa/wa/viewContentsUserReviews?type=Purple+Software&id=yourappid"]]; [self activityDidFinish:YES]; } @end 

Here's what my image looked like: Here is the .PSD I made: - the malicious link was deleted - And here is the original 250 px.png http://i.imgur.com/pGWVj.png

Now in your view controller do the following:

 #import "ActivityViewCustomActivity.h" 

And now, wherever you want to display your UIActivityViewController :

  NSString *textItem = @"Check out the yourAppNameHere app: itunes http link to your app here"; UIImage *imageToShare = [UIImage imageNamed:@"anyImage.png"]; NSArray *items = [NSArray arrayWithObjects:textItem,imageToShare,nil]; ActivityViewCustomActivity *aVCA = [[ActivityViewCustomActivity alloc]init]; UIActivityViewController *activityVC = [[UIActivityViewController alloc] initWithActivityItems:items applicationActivities:[NSArray arrayWithObject:aVCA]]; activityVC.excludedActivityTypes = @[UIActivityTypePostToWeibo, UIActivityTypeAssignToContact, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll]; activityVC.completionHandler = ^(NSString *activityType, BOOL completed) { NSLog(@"ActivityType: %@", activityType); NSLog(@"Completed: %i", completed); }; if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) { self.popoverController = [[UIPopoverController alloc] initWithContentViewController:activityVC]; CGRect rect = [[UIScreen mainScreen] bounds]; [self.popoverController presentPopoverFromRect:rect inView:self.view permittedArrowDirections:0 animated:YES]; } else { [self presentViewController:activityVC animated:YES completion:nil]; }

Here is my version of Swift - I need some custom actions, so I created this class. No need for delegates or protocols.

1. Add a custom class

 class ActivityViewCustomActivity: UIActivity { var customActivityType = "" var activityName = "" var activityImageName = "" var customActionWhenTapped:( (Void)-> Void)! init(title: String, imageName:String, performAction: (() -> ()) ) { self.activityName = title self.activityImageName = imageName self.customActivityType = "Action \(title)" self.customActionWhenTapped = performAction super.init() } override func activityType() -> String? { return customActivityType } override func activityTitle() -> String? { return activityName } override func activityImage() -> UIImage? { return UIImage(named: activityImageName) } override func canPerformWithActivityItems(activityItems: [AnyObject]) -> Bool { return true } override func prepareWithActivityItems(activityItems: [AnyObject]) { // nothing to prepare } override func activityViewController() -> UIViewController? { return nil } override func performActivity() { customActionWhenTapped() } } 

2 Use in your view controller

I bound it to a UIBarButtonItem, which calls the following

 @IBAction func actionButtonPressed(sender: UIBarButtonItem) { var sharingItems = [AnyObject]() // nothing to share... let myCustomActivity = ActivityViewCustomActivity(title: "Mark Selected", imageName: "removePin") { println("Do something") } let anotherCustomActivity = ActivityViewCustomActivity(title: "Reset All", imageName: "reload") { println("Do something else") } let activityViewController = UIActivityViewController(activityItems:sharingItems, applicationActivities:[myCustomActivity, anotherCustomActivity]) activityViewController.excludedActivityTypes = [UIActivityTypeMail, UIActivityTypeAirDrop, UIActivityTypeMessage, UIActivityTypeAssignToContact, UIActivityTypePostToFacebook, UIActivityTypePrint, UIActivityTypeCopyToPasteboard, UIActivityTypeSaveToCameraRoll] activityViewController.popoverPresentationController?.barButtonItem = sender self.presentViewController(activityViewController, animated: true, completion: nil) }

My Swift 3 DogCoffee's based implementation:

 class ActivityViewCustomActivity: UIActivity { // MARK: Properties var customActivityType: UIActivityType var activityName: String var activityImageName: String var customActionWhenTapped: () -> Void // MARK: Initializer init(title: String, imageName: String, performAction: @escaping () -> Void) { self.activityName = title self.activityImageName = imageName self.customActivityType = UIActivityType(rawValue: "Action \(title)") self.customActionWhenTapped = performAction super.init() } // MARK: Overrides override var activityType: UIActivityType? { return customActivityType } override var activityTitle: String? { return activityName } override class var activityCategory: UIActivityCategory { return .share } override var activityImage: UIImage? { return UIImage(named: activityImageName) } override func canPerform(withActivityItems activityItems: [Any]) -> Bool { return true } override func prepare(withActivityItems activityItems: [Any]) { // Nothing to prepare } override func perform() { customActionWhenTapped() } }

Here is an example of setting the email composer interface using the -activityViewController method for UIActivity. This shows how to set up a UIKit viewController or your own viewController for any purpose you choose. It supersedes the -performActivity method.

 #import <MessageUI/MessageUI.h> #import <UIKit/UIKit.h> @interface EPSuggestionsActivity : UIActivity <MFMailComposeViewControllerDelegate> @end @implementation EPSuggestionsActivity .... - (UIViewController *)activityViewController{ MFMailComposeViewController *picker = [[MFMailComposeViewController alloc] init]; picker.mailComposeDelegate = self; NSString *emailAddress = @"[e-mail]"; NSArray *toRecipients = @[emailAddress]; [picker setToRecipients:toRecipients]; [picker setSubject:@"Suggestions"]; return picker; } #pragma mark - MFMailComposeViewControllerDelegate Method - (void)mailComposeController:(MFMailComposeViewController*)controller didFinishWithResult:(MFMailComposeResult)result error:(NSError*)error { [self activityDidFinish:YES]; // Forces the activityViewController to be dismissed } @end 

Note that -activityDidFinish is called from the mail composer delegate after the user rejects the email interface. This is necessary for the UIActivityViewController interface to disappear. If you write your own viewController, he will need a delegate method, which he will call when done, and you will need to make your UIActivity subclass a delegate.
