How can I create a custom UIActivity in iOS?

Question

How can I create a custom UIActivity in iOS?

The reason I want this is to add a Review App button in one of my apps that takes the user to the review section in the App Store. How can I create such a custom UIActivity?

Answer 1

Here is my Swift Version - I needed multiple custom actions so I created this class. No need for delegates or protocols.

1. Add the 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've attached it to a UIBarButtonItem, which calls the 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) }

First, create the files. I chose to name mine ActivityViewCustomActivity

Make ActivityViewCustomActivity.h look like this:

#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 

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

Now in your view controller do this:

#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];    }
