Syntax for storing one array value as variable - ios

Question

In designing a quiz app I want to compare the answer selected by the user to the correct answer in an sqlite array.
To do this, I want to do the following on viewDidLoad:, load up the correct answer (which is an integer 1,2,3 etc.) and store it as qACorrect variable.
Then on - (IBAction)submit:(id)sender to have it compare the variable qACorrect with qASelected
Could someone help me with the syntax for assigning the value of qACorrect which is imported in the array to the new variable qACorrect? I am using the rest of this code on ViewDidLoad to load up the questions:
- (void)viewDidLoad
{
MySjtQuestionslist * MySJT =[[MySjtQuestionslist alloc] init];
self.SJT = [MySJT getMySjtQuestion];
[self.QuestionText setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestion];
[self.labelA setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestionA];
[self.labelB setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestionB];
[self.labelC setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestionC];
[self.labelD setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestionD];
[self.labelE setText:((SjtQuestionlist *) [self.SJT objectAtIndex:0]).SJTQuestionE];
[super viewDidLoad];
[scroller setScrollEnabled:YES]; //scrollview stuff
[scroller setContentSize:CGSizeMake(320, 1000)]; //scrollview stuff
}

Answer 1

Based on the assumption that qAVariable is the value selected from the segmented controller. & qACorrect is of NSString Type,
You don't need to implement an extra "submit" method. On segment value change, you can do this.
- (IBAction)onSegmentValueChanged:(UISegmentedControl *)sender
{
NSString *selAnswer= [sender titleForSegmentAtIndex:[sender selectedSegmentIndex]];
if ([selAnswer isEqualToString:qACorrect])
{
score = score + 1;
}
else
{
score = score - 1;
}
}
Update:
for getting integer value, use this:
int qACorrect= [[sender titleForSegmentAtIndex:[sender selectedSegmentIndex]] intValue];
Let me know if more info needed..
