It is very simple app, just want to confirm if the selected question real answer is yes or no?

Answer 1

there are several method to do this simple task.

one is make dictionary with keys (Question, Answer) and add to array as

NSArray *questions = @[@{@"Question":@"Question 1 Text", @"Answer":@YES},
                       @{@"Question":@"Question 1 Text", @"Answer":@NO}]; 

And Generate a random number and get the question dictionary from array and save the reference of question dictionary for further comparison.

NSDictionary *curQuestion = questions[(rand()%questions.count)];
NSString *question = curQuestion[@"Question"];
BOOL answer = [curQuestion[@"Answer"] boolValue];

Answer 2

创建一个字典数组（带有两个键“ Question”和“ Answer”的字典），当一个问题被回答时，您可以从数组访问相应的字典，然后获得该问题的答案。
