Question

In my previous project I used transitionFromView successfully, now I created new project today this time its ARC enabled, I copied the old code and pasted it but its not working. I put a breakpoint, executed it step by step but not working.

working code

quiz *quizObj = [[quiz alloc]init];
self.vc = quizObj;
[quizObj release];

[UIView transitionFromView:self.view toView:self.vc.view duration:1 options:UIViewAnimationOptionTransitionCurlUp completion:^(BOOL finished) {
}];

Not working code

EnterPhoneNumber *epnObj = [[EnterPhoneNumber alloc]init];

        [UIView transitionFromView:self.view toView:epnObj.view duration:1 options:UIViewAnimationOptionTransitionCurlUp completion:^(BOOL finished) {
        }];

project has no warnings or errors, but still this code is not working.

Answer 1

tries to put the method inside a performSelector

...
[self performSelector:@selector(actionView) withObject:nil afterDelay:3];
...

- (void)actionView {
    [UIView transitionFromView:self.view toView:self.vc.view duration:1 options:UIViewAnimationOptionTransitionCurlUp completion:^(BOOL finished) {
}];
}
