How to use QIOApplicationDelegate

[saqirltu]

Hi, from a lot of posts I found QIOApplicationDelegate in Src/qtbase/src/plugins/platforms/ios/qiosapplicationdelegate.h is the thing to use to achieve AppDelegate in iOS apps. My question is how to use it. I found people speaking about either category extending or subclassing. Will they both work?

Another more important question, after implementing the class, shall I create an instance of it in main.cpp?

Thanks all!

Hi and welcome to devnet,

It's not a class you usually subclass, it's a class used by the QPA which can change from a version of Qt to the other.

What do you need to subclass for ?

Hi @SGaist

I need it for handling the push notifications.

I kinda managed it by following @benlau 's approach.

Now wondering if this is the appropriate way of doing it.

AFAIK, it is. I'd just check Qt's sources to see if the method is already implemented and is doing something.

I have checked Qt source and it did nothing. That is why I suggest people to do so. However, I found that there has other library project that will override the method too. So, people should use at their own risks.
