ios8 UIModalTransitionStylePartialCurl doesn't work properly

Question

Under ios 8 using presentViewController modalTransitionStyle = UIModalTransitionStylePartialCurl disappear all page. I want it to work like ios 7.

Answer 1

I had the same issue and I applied this fix, it worked for me on iOS 8 and Xcode 6.

    [_mapToolbarController setModalTransitionStyle:UIModalTransitionStylePartialCurl];
    [self presentViewController:_mapToolbarController animated:YES completion:^{
        [_mapToolbarController.view.superview addSubview:self.view];
    }];

Obviously, _mapToolbarController will be the controller that you want to present. To see why you'd need this, add a breakpoint at the line in the completion handler. Do the animation, and you'll see in the completion handler that the curling animation had just finished and everything was perfectly fine. For some reason that I can't explain, in iOS 8 you'll need to tell the iOS framework to "keep" the curled view and make sure it doesn't get thrown away. The code in the completion handler tries to "keep" the soon-to-be-faded curled view onto the screen. Note that in this context, self.view is the view that is being curled.
