I have one UIPickerview. I have a json response. I have a three text fields. If user select the first text field display picker view then user select the particular item. And second and third text field also same.
My requirement is if user select the the particular item in first picker view second and third picker view does not showing the item. And second and third also same. Again user selects the first text field and change another security question. Then in this scenario first time selected security needs to be added to the array. Second and third also same. So I am writing the below code. My problem is security questions are repeating in picker view.
- (void)viewDidLoad
{
UITapGestureRecognizer *tap = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(dismissKeyboard)];
[self.view addGestureRecognizer:tap];
QArray = [[NSMutableArray alloc]init];
QidArray = [[NSMutableArray alloc]init];
pickerviewRowCount++;
NSMutableDictionary *secQuestions=questionInfo[@"SecurityQuestion"];
NSLog(@"Dictionary values of security question is :%@",secQuestions);
for (NSDictionary *dict in secQuestions){
pickerviewRowCount++;
[QidArray addObject:[dict valueForKey:@"QuestionID"]];
[QArray addObject:[dict valueForKey:@"Question"]];
NSLog(@"QID: %@ , Q:%@",[dict valueForKey:@"QuestionID"],[dict valueForKey:@"Question"]);
}
bloodGroup = [[UITextField alloc]initWithFrame:CGRectMake(10, passManagerLbl.frame.origin.y+passManagerLbl.frame.size.height+45, screenWidth-20, 50)];
bloodGroup.placeholder = @"Please Select Your Option";
[scrollview addSubview:bloodGroup];
ansField1 = [[UITextField alloc]initWithFrame:CGRectMake(10, bloodGroup.frame.origin.y+bloodGroup.frame.size.height+45, screenWidth-20, 50)];
ansField1.placeholder = @"Please enter Answer";
ansField1.delegate = self;
