Why is my IBAction begin triggered twice?

[rabbigarfinkel1]

Hello,

I am trying to write a simple program that asks users yes/no questions and, based on those answers, tells them where they stand on the political spectrum.

I have a variable in my code called "questionnumber." My thought was that every time the user clicked the "nextbutton" in my IB interface, I would increase the "questionnumber" variable by 1 and thus present a new question.

This works for questions 1 and 2. But then it starts skipping every other question. Can someone tell me why? I'm stumped! The code appears below: (My IB interface buttons are keyed for "touch up inside" in case that makes a difference.)

#import "MainView.h"
#import <Foundation/Foundation.h>

@implementation MainView
@synthesize Question;
@synthesize mispar;


int conservative = 0;
int liberal = 0;
int questionnumber = 0;

- (IBAction)agreebuttonid)sender {

++liberal;

}

- (IBAction)disagreebuttonid)sender {

++conservative;

}

- (IBAction)nextbuttonid)sender {

++questionnumber;

switch (questionnumber) {

case 1:

Question.text = @"text of question 1";
break;

case 2:

Question.text = @"test of question 2";
break;


case 3:

Question.text = @"text of question 3";
break;

case 4:

Question.text = @"text of question 4";
break;


case 5:
Question.text = @"text of quesiton 5";
break;

case 6:
Question.text = @"text of question 6";
break;

case 7:
Question.text = @"text of question 7";
break;

case 8:
Question.text = @"text of question 8.";
break;

case 9:
Question.text = @"text of question 9";
break;

default:
break;
}
}

@end

Check you haven't wired up that action twice to the button in IB. It may be being called on touch down and release.

The same thing is happening to me.

I confirmed in IB that the only handled event for the button is "touch up inside" and that there is only one received action in my "file's owner" for the method that is being called twice.

For me, the double calling is happening even the first time I touch the button.

Either the method is getting called twice, or something else is incrementing your questionnumber.

I'd add some NSLogs inside your next button action.

NSLog(@" questionnumber before: %d", questionnumber);
questionnumber++;
NSLog(@" questionnumber after: %d", questionnumber);

You'll immediately see if nextbutton is being called twice, or whether someone else is changing questionnumber.
