- (void)viewWillAppear:(BOOL)animated detect custom animation
I have a button which when pressed pushes a view controller however i'm using a custom animation so pushViewController: childController animated:
is set to NO. What i want to do though is detect this custom animation in my - (void)viewWillAppear:(BOOL)animated
method and write an if statement like this;
- (void)viewWillAppear:(BOOL)animated {
if (customAnimation occured) {//Do this}
else {//Do this}
}
This is the method for my button which pushes the view controller.
- (void)nextPressed:(id)sender {
childController = [[CategoryOneDetailControll开发者_运维百科er alloc] initWithNibName:xibDownName bundle:nil];
[UIView beginAnimations: @"Showinfo"context: nil];
[UIView setAnimationCurve: UIViewAnimationCurveEaseInOut];
[UIView setAnimationDuration:0.75];
[self.navigationController pushViewController: childController animated:NO];
[UIView setAnimationTransition:UIViewAnimationTransitionCurlDown forView:self.navigationController.view cache:NO];
[UIView commitAnimations];
[childController release];
}
Any help would be much appreciated, thanks, Sami.
If you don't use standard animations, I think your best bet is to add a property to your pushed view controller that is set to YES
in case of a custom animation (and NO
by default to not break any existing behavior). Then you can check that property in viewDidAppear:
.
If you need your custom logic to be executed after the animation has run, you might want to set up an animation completion handler or block.
