Question

I have one UIViewController and inside I have NSArray that I put my correct answer,and also I have 3 buttons, and 3 NSArray for their titles, I want to check if my buttons title was equal to the correct answer then goes to the correct page else goes to the wrong page
would you please help me to this implementation:
Thanks in advance!
Here is my code:
NSString *correctOne = #"test1";
NSString *correctTwo = #"test2";
NSString *correctThree = #"test3";
NSString *correctFour = #"test4";
NSString *correctFive = #"test5";
NSString *correctSix = #"test6";
NSString *correctSeven = #"test7";
NSString *correctEight = #"test8";
correctComments = [[NSArray alloc] initWithObjects: correctOne, correctTwo, correctThree,
correctFour, correctFive, correctSix, correctSeven, correctEight, nil];
int rand = arc4random()%8;
NSString *correct = [correctComments objectAtIndex:rand];
[test setTitle:(firstAnswer) forState:UIControlStateNormal];
[test setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
[test setTag:0];
[ansONE setTitle:(secondAnswer) forState:UIControlStateNormal];
[ansONE setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
[ansONE setTag:1];
[ansTWO setTitle:(threeAnswer) forState:UIControlStateNormal];
[ansTWO setTitleColor:[UIColor blueColor] forState:UIControlStateSelected];
[ansTWO setTag:2];
- (IBAction)suivant:(id)sender {
//MY Question is how should I check my button title and correctComments
}

Answer 1

- (IBAction)suivant:(id)sender {
UIButton *button = (UIButton *)sender;
int correctIndex = ...;
BOOL thisIsTheCorrectButton = (button.tag == correctIndex);
// Do whatever
}

Answer 2

At first you have to store correct answer from your code snippet to a property:
self.correctAnswer = correct;
Then do the comparision of those strings:
- (IBAction)suivant:(UIButton *)sender {
// You wanted to check for title:
if ([sender.currentTitle isEqualToString:self.correctAnswer]) {
// Correct...
}
else {
// Wrong...
}
}
