Passing which button that was pressed to another View JSON - ios

Question

I have a NSMutableArray in a view where I parse some JSON data to a Table View. I also have three buttons on the bottom: Button 1, Button 2, Button 3. If I select Button 2, the JSON data string changes to Link 2 etc...
Now, when I click on a cell, the value (text) passes to a UITextView in the Second View Controller. But what I want, is to also pass which button that was pressed, so the string name to the UITextView parses correct. Because now, when I select for example button 2 and click on a cell, the Text View on Second View Controller gets blank, because I only set the string name to #"message", and the string name for the text when selected Button 2 is #"tweet".
Here's my code:
#interface DEMOSecondViewController ()
#end
#implementation DEMOSecondViewController
#synthesize tableView = _tableView, activityIndicatorView = _activityIndicatorView;
#synthesize fontForCellText;
#synthesize btnFaceBook, btnTwitter, btnTwitter2;
#synthesize strURLToLoad;
#synthesize movies;

As you can see in the first view, I have 3 different links I'm parsing. How can I set an if-statement in viewDidLoad in PostsNextView? Like, if the btnFacebook is selected: textView.text = [theMovie objectForKey:#"message"]; and if btnTwitter is selected: textView.text = [theMovie objectForKey:#"tweet"]; ?
Would really appreciate a solution!

Revised Answer (This will be high level):
Add Tag Values to each of your buttons
When a button is clicked you can get its tag with the getTag (also tag can be set with setTag) call - please check the API for details
As you are programatically loading your next view controller when you create it
PostsNextView *newView = [[PostsNextView alloc] init];
newView.theMovie = movie;
// You could add a call here to set the value
[newView setTheVaue:valueIWantToSet]
You would make a property called TheValue in your newView controller
When you actually make your call to change to the new view controller
[self.navigationController pushViewController:newView animated:YES];
The data value you desire will already be set.
