UITextView make application crash when becomeFirstResponder called

Question

I have a UITextView in a UIView. When viewLoad, I had a UIPickerView within a UIAlertView with "OK" button. When I select any value from picker and click "OK" I required to make UITextView active.
For that I have written [<myTextView> becomeFirstResponder]; delegate method of UITextView. As soon as this method execute it make textViewShouldBeginEditing delegate method to be invoked. This method executes correctly and I have return TRUE here, but after that the execution goes back to the line [<myTextView> becomeFirstResponder]; and then the application get crashed.
UIAlertView Delegate method is as below:

- (void)customIOS7dialogButtonTouchUpInside: (CustomIOS7AlertView *)alertView clickedButtonAtIndex: (NSInteger)buttonIndex
{
    NSLog(@"Button at position %d is clicked on alertView %d.", (int)buttonIndex, (int)[alertView tag]);
    [alertView close];
    [self.updateTV becomeFirstResponder];
}

Here in above code application crash at [self.updateTV becomeFirstResponder];
The crash log shows below:

Help me get out of this. I am stuck in this since 2 days.
My project is already on AppStore and that is working correctly. But When I run it in iOS 10 device it create this issue.

Thank you in advance

update your question with textfield textViewShouldBeginEditing method code — Himanshu Moradiya, Dec 09 '16 at 06:22
@ Mr.Bista No. I have used the method once. And @ Himanshu Moradiya I have taken UITextView in my codeing and related delegate method is "textViewShouldBeginEditing" only. So I think there is no need to update the question. — Er. Vihar, Dec 09 '16 at 06:33
@Er.Vihar its problem with your viewconroller present request is different . you present UICompatibilityInputViewController controller but its refernce OGAddUpdateViewController contoller and same textfield in UIInputWindowController so check that controller — Himanshu Moradiya, Dec 09 '16 at 06:37
UIView its a default view or you create one UIview programically and you add it in main view — Himanshu Moradiya, Dec 09 '16 at 06:41
That is a default View. My project is already on AppStore and that is working correctly. But When I run it in iOS 10 device it create this issue. — Er. Vihar, Dec 09 '16 at 06:44
@ Sathi Reddy I have updated my question with the code where the application is crash. — Er. Vihar, Dec 09 '16 at 07:21

Try this it is working while ...

I encountered this problem before.

Problem:

You have to ensure that the view you will assign to inputView or inputAccessoryView doesn't belong to any parent view. When you create these views from a xib inside a ViewController, by default they are set as subviews of a superview.

Solution Tips:

Use the method removeFromSuperview on the view you will assign to inputView or inputAccessoryView

from : https://stackoverflow.com/a/25882277/3901620

while from xib :

[self.DatePickerView removeFromSuperview];
[Textfield setInputView:self.DatePickerView];
[Textfield setInputView:self.DatePickerView];
