How Popup Keyboard After Segue to New Naviagtion Controller Animation Has Finished - objective-c

Question

I segue from a tableview to detail view controller using custom segues.
#implementation QuickNoteFlipSegue
- (void) perform {
UIViewController *src = (UIViewController *) self.sourceViewController;
UIViewController *dst = (UIViewController *) self.destinationViewController;
dst.navigationItem.hidesBackButton = YES;
[UIView transitionWithView:src.navigationController.view duration:1.00
options:UIViewAnimationOptionTransitionCurlUp
animations:^{
[src.navigationController pushViewController:dst animated:NO];
}
completion:^(BOOL finished){
if (finished) {
}
}];
}
#end
What I would like to do it when the transition has finished, popup the keyboard for my textview.
I currently do this by calling
[textView becomeFirstResponder];
This pops up the keyboard OK but before the transition animation has finished. How to detect when the animation has finished before I popup the keyboard?
I should maybe put something is the completion of the animation, but how to make the custom segue aware of the textview in it's destination?

Answer 1

Do:
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[textView becomeFirstResponder];
}

Answer 2

Add a method to your DestinationViewController:
-(void)openKeyboard
{
[textView becomeFirstResponder];
}
Then change your perform method:
- (void) perform {
UIViewController *src = (UIViewController *) self.sourceViewController;
DestinationViewController *dst = (DestinationViewController *) self.destinationViewController;
dst.navigationItem.hidesBackButton = YES;
[UIView transitionWithView:src.navigationController.view duration:1.00
options:UIViewAnimationOptionTransitionCurlUp
animations:^{
[src.navigationController pushViewController:dst animated:NO];
}
completion:^(BOOL finished){
if (finished) {
[dst openKeyboard];
}
}];
}
