pass data between UIViewControllers

Leveraging RESideMenu https://github.com/romaonthego/RESideMenu in my app, now has an issue of passing some urlString related to lists in sideMenuViewControll to show its web page in right UIWebView.

Original codes like below:

case 2: {
    navigationController.viewControllers = @[[self.storyboard instantiateViewControllerWithIdentifier:@"second"]];
    [self.sideMenuViewController hideMenuViewController];
}
    break;

"second" is for secondViewController that has a UIWebView for showing web page at right side. secondViewController has a property: urlString.

My intention is to show its web page when selecting "Profile". Tried several way, however, I can't find one to set urlString after navigationController.viewControllers = @[[self.storyboard instantiateViewControllerWithIdentifier:@"second"]];

How can I set and pass urlString so that it could be used like NSUrl * url = [NSURL URLWithString:urlString]?

After tried every method I could get, find a workaround by using [navigationController.viewControllers[0] setTitle:urlStrings] might works.

Is doing such correctly?

First of all import your secondViewController in your first View Controller's .m file

Create in secondViewController's .h file

@property (strong, nonatomic) *NSString passedURL;

Then give the storyboard name in Attribute Inspector. Now, on button event of profile or whatever

secondViewController *svc = [self.storyboard instantiateViewControllerWithIdentifier:@"secondViewController"];
svc.passedURL = urlString;
[self presentViewController:svc animated:YES completion:nil];

Thats it. Hope that it works for you.

The Below line shows that,

navigationController.viewControllers = @[[self.storyboard instantiateViewControllerWithIdentifier:@"second"]];

You are trying to access the array of ViewControllers, but I am not sure why you want all the ViewControllers. I think you can get the secondViewController like this below and set the string

 secondViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"secondViewController"];
    secondViewController.urlString = urlString;
