Implement custom Cancel Button in a SDK

Question

I want to implement payment functionality with paysbuy SDK....The problem is it doesnot have any cancel option on it so that user can cancel the operation of close after the payment has been successful.

By default SDK provides a method that opens the default WebView that covers the whole part of the screen..And there is no any cancel option..

I just want to add a cancel button by load the payment on the specific view..or viewcontroller..I tried using in container view..to load the view inside the container view and a cancel button outside the container view ,but when i try this process,it shows by default in Full Screen WebView.Also tried creating a PopUP but didnot succeed

So, how can i load the webview of SDK on a specific portion of my view so that i can put a Cancel button??

This is the method that the sdk provides to start the service

- (void) callServiceWithCurrentView :(UIViewController *) currentViewController
                             invoice:(NSString *)invoice
                                item:(NSString *)item
                              amount:(NSString *)amount
                       paypal_amount:(NSString *)paypal_amount
                      transferMethod:(NSString *)transferMethod
                    customerLanguage:(NSString *)customerLanguage
                       operator_name:(NSString *)operator_name
                      operator_email:(NSString *)operator_email
                     operator_mobile:(NSString *)operator_mobile
                    operator_address:(NSString *)operator_address
                     operator_detail:(NSString *)operator_detail;

Here we can see the callServiceWithCurrentView method shows the target as currentviewcontroller so i think it loads by default in full screen mode on the viewcontroller....

Here is how i implemented in swift

   paysBuy?.callServiceWithCurrentView(self, invoice: "343434343", item: "App Fee", amount: "10", paypal_amount: "1", transferMethod: "1", customerLanguage: "E", operator_name: "PAYSBUY", operator_email: "abc@paysbuy.com", operator_mobile: "0888888888", operator_address: "PAYSBUY.COM", operator_detail: "PAYMENT")

And a delegate method that handles the response in case of success or failutre

extension PaysBuyHelper:PaysbuySDKDelegate{
    func responseWithResult(result: String!, andInvoice invoice: String!) {

        //here is the response of the payement

        println(result)
        println(invoice)

        if result == "00" {

            println("transaction complete and below is the invoice number")
            println(invoice)

        }else if result == "90"{

            println("transaction incomplete information")

        }

    }

}

Here is the work that i have done.... https://drive.google.com/file/d/0Bzk4QVQhnqKmVno5NGdPUV9ITkE/view?usp=sharing

Modal controllers are presented within the frame context of the controller which is deemed to define the presentation context.

An option you have is to make the controller which calls callServiceWithCurrentView define the context for any modal presentation which can then be used to restrict the area on screen that is used.

You do this in XCode by clicking on your presenting controller and selecting the Defines Context checkbox. In code you can set the definesPresentationContext to TRUE.

For this to be of use to you, you need the frame for the presenting controller to not be full screen. The ideal situation would be that this is a controller inside a UINavigationController.

Options:

1) Your presenting controller is inside a navigation controller with a navigation bar. Effectively it is a child controller. The screen footprint it uses is dependent on whether it goes under the top and bottom bars. a) Set your controller so that content does not go under the top bars. This effectively makes the frame under the navigation bar. b) When you call callServiceWithCurrentView, add a cancel button on the navigation bar. c) If you set the controller to define the presentation context properly, then the UIWebView should show up under the navigation bar and you can see your new cancel button.

2) If not in a navigation controller, then rather than calling the method directly, add a child controller inside a sub view above which you put your cancel button. Have this child controller do the call callServiceWithCurrentView. Following the same mechanism, make this child controller define the context. Any modal UIWebView should then only cover the area of the child controller.

Hope this gives you some options.
