How can I display poll results upon voting?

I'm writing an app where users can take different polls and view the results of each poll after submitting their vote, but I don't know how to display the results in the app after the user submits their vote. I'm using the Parse Starter Project template and I have the function written for a single voting option (each option takes the form of a button, which submits a vote for that option). This code works, but when I press a button on iOS simulator, I get a message that says, "Thread 1: breakpoint 1.1" in the ViewController.h file on the @property line. Here is the code I have written so far in my ViewController.m file:

- (NSString *) addVote:(NSString *) countOption1 {
    NSString *result = [countOption1
                        stringByAppendingString:countOption1];
    return result;
}

- (IBAction)addOneVote {
    [self addVote: self.countOption1.text];


}

@synthesize countOption1;

And here is the code I've written in my ViewController.h file:

@property (weak, nonatomic) IBOutlet UILabel*     
countOption1;

Do I need to make it so that the votes are submitted to my Parse.com cloud storage? How do I do that, and how do I make it so that the votes are counted and the results for each poll is displayed upon each vote?
