Can't select payment method

[PeterDolenec]

Hi,
I am using the dropInComponent. After I receive payment methods from server I present the dropInComponent viewController. To here, everything works fine, but when I try to select one of the options nothing happens. I tried to debug the problem and I found out that the function "tableView didSelectRowAt indexPath" in class "ListViewController" is called and it triggers selection handler on selected component. But then in class "PaymentMethodListComponent" where selection handler should trigger delegate's function "didSelect" (in line 46), the delegate is nil, so the function is not triggered. Also the close button is not working. The problem is clearly seen in the attached gif (you can see the press event and that it doesn't open the next screen).

Expected behavior
It should display form for selected credit card.

Hi @PeterDolenec ,

Thanks for reaching out.

Are you retaining the DropInComponent instance strongly?, the only reason I can think of for this behavior is that the DropInComponent instance is not retained, so it gets deallocated, since the DropInComponent instance is set as the delegate for the PaymentMethodListComponent, and PaymentMethodListComponent doesn't retain it to prevent a retain cycle.

Hi @mohammedDehairy

Thanks for quick reply.

You were right. Setting strong retention to DropInComponent solved the problem. A rookie mistake. 🤦‍♂️

Thanks again.

I'm retaining the DropInComponent instance strongly, but when I click the Payment method Icon or the area
except the UIStackView of the ListCell, it works,

Hey @yuchuanxing

I am not sure that I understand your message correctly.
Could you provide more details and attach a Video / GIF ?

UPD

I assume the same issue is addressed in #705 ?

How to set DropInComponent as strong retention?

Thanks

Hi @ronakcc ,

you need to retain the dropInComponent instance to a property in the same class for example, i.e self.dropInComponent = DropInComponent()
