AppExtension - Share Extension

Share Extension Functionality

TODO::

Some code for your main App Extension file:

Your view controller should look something like the following to start:

@interface ShareViewController ()

@end

@implementation ShareViewController

- (BOOL)isContentValid {
    // Do validation of contentText and/or NSExtensionContext attachments here
    return YES;
}

- (void)didSelectPost {
    // This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
    
    // Inform the host that we're done, so it un-blocks its UI. Note: Alternatively you could call super's -didSelectPost, which will similarly complete the extension context.
    [self.extensionContext completeRequestReturningItems:@[] completionHandler:nil];
}

- (NSArray *)configurationItems {
    // To add configuration options via table cells at the bottom of the sheet, return an array of SLComposeSheetConfigurationItem here.
    return @[];
}

@end

This is just a rough dump of some code I was playing with to get a url to share

@implementation ShareViewController
{
    NSUInteger _itemCount;
    NSString* _invokeArgs;
}


- (BOOL) isContentValid
{
    // Do validation of contentText and/or NSExtensionContext attachments here
    return YES;
}

- (void) didSelectPost
{
    // This is called after the user selects Post. Do the upload of contentText and/or NSExtensionContext attachments.
    NSLog( @"distriqt:SHAREEXTENSION:didSelectPost" );
    
    NSLog( @"distriqt:SHAREEXTENSION:%@", self.contentText );
    
    NSExtensionItem* item = self.extensionContext.inputItems.firstObject;

    _invokeArgs = NULL;
    _itemCount = item.attachments.count;
    
    for (NSItemProvider* itemProvider in item.attachments)
    {
        if ([itemProvider hasItemConformingToTypeIdentifier: (NSString*)kUTTypeURL])
        {
            NSLog( @"distriqt:SHAREEXTENSION:item is url" );
            [itemProvider loadItemForTypeIdentifier: (NSString*)kUTTypeURL
                                            options: nil
                                  completionHandler:^(id<NSSecureCoding>  _Nullable item, NSError * _Null_unspecified error)
            {
                NSURL* url = (NSURL*)item;
                NSLog( @"distriqt:SHAREEXTENSION:loaded:%@", url );
                if ([url.absoluteString rangeOfString: @"youtube"].location == NSNotFound)
                {
                    
                }
                else
                {
                    
                }
                [self invokeApp: url.absoluteString];
            }];
        }
        else if ([itemProvider hasItemConformingToTypeIdentifier: (NSString*)kUTTypeImage])
        {
            NSLog( @"distriqt:SHAREEXTENSION:item is image" );
            [itemProvider loadItemForTypeIdentifier: (NSString*)kUTTypeImage
                                            options: nil
                                  completionHandler:^(id<NSSecureCoding>  _Nullable item, NSError * _Null_unspecified error)
            {
                [self invokeApp: @""];
            }];
        }
    }

}


- (NSArray *) configurationItems
{
    // To add configuration options via table cells at the bottom of the sheet, return an array of SLComposeSheetConfigurationItem here.
    return @[];
}


- (void) invokeApp: (NSString *)invokeArgs
{
    // Prepare the URL request
    // this will use the custom url scheme of your app
    // and the paths to the photos you want to share:
    NSString * urlString = [NSString stringWithFormat: @"%@://%@", @"distriqt-test", ( NULL == invokeArgs ? @"" : invokeArgs ) ];
    NSURL * url = [NSURL URLWithString: urlString];
    
    NSString *className = @"UIApplication";
    if (NSClassFromString( className ))
    {
        id object = [ NSClassFromString(className) performSelector: @selector(sharedApplication) ];
        [object performSelector: @selector(openURL:) withObject: url];
    }
    
    // Now let the host app know we are done, so that it unblocks its UI:
    [super didSelectPost];
}

@end

This code uses a custom url scheme to launch the application so you'll need to add the following to your InfoAdditions in your application descriptor:

    <key>CFBundleURLTypes</key>
    <array>
        <dict>
            <key>CFBundleURLSchemes</key>
            <array>
                <string>distriqt-test</string>
            </array>
        </dict>
    </array>
