XCode 7 Date picker cause crash of application

Question

Hi I need to integrate date picker with inputView, I am on Xcode7. Using below code the application cause exception. The exception happening while I am touching UITextField element.

Here is the relevant part of the code where the date picker used.

@property (weak, nonatomic) IBOutlet UIDatePicker *graphDate;
@property (weak, nonatomic) IBOutlet UITextField *fromdate;
@property (weak, nonatomic) IBOutlet UITextField *toDate;
............................................................
..............................................................

[_graphDate setDatePickerMode:UIDatePickerModeDateAndTime];

............................................................
..............................................................

[_graphDate setHidden:TRUE];
[_graphDate setFrame:CGRectMake(600, 600, 400, 162)];
_toDate.inputView = _graphDate;
_fromdate.inputView = _graphDate;
_graphDate.date = [NSDate date];

The exception message,

 Terminating app due to uncaught exception 'UIViewControllerHierarchyInconsistency', reason:
 'child view controller:<UICompatibilityInputViewController: 0x80286850>
 should have parent view controller:<VALiveViewController: 0x7cbeda00>
 but requested parent is:<UIInputWindowController: 0x7cc25a00>'

I already refereed the answer here UIViewControllerHierarchyInconsistency in 64 bit iOS device but no idea how to apply here, I am newbie in IOS.

Any help will be appreciated.
Thanks,
Haris

I'm wondering how picker is related to the crash!!! DO you have any code related to adding child view controller ? — Teja Nandamuri, Dec 05 '15 at 18:06
The exception happening while I am touching on `UITextField` — Haris, Dec 05 '15 at 18:09
put a breakpoint on textfield delegate methods, and see if it hits any of them before crashing ? — Teja Nandamuri, Dec 05 '15 at 18:10
try to put a breakpoint on textFieldShouldBeginEditing and see if it hits when u touch the textfield — Teja Nandamuri, Dec 05 '15 at 18:11
Yes IT hitting on the delegate method before crash , here is the code - `(void)textFieldDidBeginEditing:(UITextField *)textField { [self animateTextField: textField up: YES]; if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPhone) { [_graphDate setHidden:FALSE]; }` — Haris, Dec 05 '15 at 18:28
did u move the breakpoint between those lines, to see where it crashes? — Teja Nandamuri, Dec 05 '15 at 18:41
