I am stuck in navigationcontroller. Here are screenshots. 1)from this page i am initializing paypal sdk. I am presenting paypal sdk pages.
2) this page is presenting only for first time.
3) and then this page is navigating automatically..now when i clikc on cancel it will dismissed. and next time when i will click on continue from first page directly this page will present with perfect UI.
Dave from PayPal here.
@vivek, if you have not already done so, please download the latest version of the PayPal iOS SDK and let us know whether that solves your problem.
