Use Objective-C++ (*.mm) code to mix C++ code with Objective-C (limitations apply, google for "Objective-C++").

Use the qmake OBJECTIVE_SOURCES variable to add your *.mm sources and have them compiled and linked with the rest of your C++ Qt project.

That let's you easily call Objective-C APIs and even instantiate Objective-C classes from within C++.

Haven't read everything, but I guess this here shows you concrete code:

Haven't heard about that, but maybe its more a Nokia store thing?

On the other hand it's easy to write plugins with Qt and load them dynamically at runtime. Any runtime "Did the user pay for this?" checks beyond that are off course highly "App Store dependent".
