Share File

Sometimes we need to share the local file or from url . for this we need to follow some steps.

here I have taken PDF file which has to share .

1: If the file is pre loaded then access their file path by giving their name ex:abc.pdf

NSString *filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:@"Heading1.PDF"];
    NSString *str = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];

1 2	NSString filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) firstObject] stringByAppendingPathComponent:@"Heading1.PDF"]; NSString str = [NSString stringWithContentsOfFile:filePath encoding:NSUTF8StringEncoding error:&error];

after this we can share .

- (IBAction)share:(id)sender {
    
    NSData *pdfData = [NSData dataWithContentsOfFile:filepath];
    NSArray *activityItems = [NSArray arrayWithObjects: pdfData, nil];
    UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];
    //if iPhone
    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {
        [self presentViewController:activityController animated:YES completion:nil];
    }
    //if iPad
    else {
        // Change Rect to position Popover
        UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:activityController];
        [popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/4, 0, 0)inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];
    }

    
    
}

- (IBAction)share:(id)sender {

NSData *pdfData = [NSData dataWithContentsOfFile:filepath];

NSArray *activityItems = [NSArray arrayWithObjects: pdfData, nil];

UIActivityViewController *activityController = [[UIActivityViewController alloc] initWithActivityItems:activityItems applicationActivities:nil];

//if iPhone

if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) {

[self presentViewController:activityController animated:YES completion:nil];

}

//if iPad

else {

// Change Rect to position Popover

UIPopoverController *popup = [[UIPopoverController alloc] initWithContentViewController:activityController];

[popup presentPopoverFromRect:CGRectMake(self.view.frame.size.width/2, self.view.frame.size.height/4, 0, 0)inView:self.view permittedArrowDirections:UIPopoverArrowDirectionAny animated:YES];

}
