presentOpenInMenuFromRect not working DocumentHandler.h - QuickLook

Question

I'm using documenthandler cordova plugin in where if I click the button I get the pdf in the document handler from the url which works fine, so that I can save the pdf into iBooks.

Now, instead of opening the document in the viewer and clicking the share button and then click again to save into iBooks I need to be able to trigger the share button without opening the document. I know this can be done using presentOpenInMenuFromRect instead of presentViewControllerbut it does not work for some reason, code below:

#import "DocumentHandler.h"

@implementation DocumentHandler

- (void)HandleDocumentWithURL:(CDVInvokedUrlCommand*)command;
{
    CDVPluginResult *commandResult = [CDVPluginResult resultWithStatus:CDVCommandStatus_OK messageAsString:@""];

    __weak DocumentHandler* weakSelf = self;

    dispatch_queue_t asyncQueue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
    dispatch_async(asyncQueue, ^{

        NSDictionary* dict = [command.arguments objectAtIndex:0];

        NSString* urlStr = dict[@"url"];
        NSURL* url = [NSURL URLWithString:urlStr];
        NSData* dat = [NSData dataWithContentsOfURL:url];
        NSString* fileName = [url lastPathComponent];
        NSString* path = [NSTemporaryDirectory() stringByAppendingPathComponent: fileName];
        NSURL* tmpFileUrl = [[NSURL alloc] initFileURLWithPath:path];
        [dat writeToURL:tmpFileUrl atomically:YES];
        weakSelf.fileUrl = tmpFileUrl;

        dispatch_async(dispatch_get_main_queue(), ^{
            QLPreviewController* cntr = [[QLPreviewController alloc] init];
            cntr.delegate = weakSelf;
            cntr.dataSource = weakSelf;

            UIViewController* root = [[[UIApplication sharedApplication] keyWindow] rootViewController];

            [root presentViewController:cntr animated:YES completion:nil];//this works fine and open the document with share button

            CGRect rect = CGRectMake(0, 0, 1024, 768);
            [root presentOpenInMenuFromRect:rect inView:self.view animated:YES]; // this doesn't work where
            //I want to see only sharing options
            //here are errors,one of them is /Property'view' not found on object of type ''DocumentHandler
        });


        [weakSelf.commandDelegate sendPluginResult:commandResult callbackId:command.callbackId];
    });
}



#pragma mark - QLPreviewController data source

- (NSInteger) numberOfPreviewItemsInPreviewController: (QLPreviewController *) controller
{
    return 1;
}

- (id <QLPreviewItem>) previewController: (QLPreviewController *) controller previewItemAtIndex: (NSInteger) index
{
    return self;
}

#pragma mark - QLPreviewItem protocol

- (NSURL*)previewItemURL
{
    return self.fileUrl;
}

@end

I need help please :(

EDIT: see the image what I'm trying to achieve:

Answer 1

presentOpenInMenuFromRect is a UIDocumentInteractionController method. I do not think you are using one in this code, unless your root view controller is a UIDocumentInteractionController, which would be very very weird.

Instead of instantiating and presenting a QLPreviewController, instantiate an UIDocumentInteractionController and present the popover from the rect corresponding to the document's icon.

To do this, check out the UIDocumentInteractionController documentation. You'll see there is an interactionControllerWithURL: method that you can use to instantiate an UIDocumentInteractionController pointed at your file. You can then call presentOpenInMenuFromRect:inView:animated: to show the popover you want.
