Integration of iOS frameworks in Qt Creator (Qt, QML)
-
Hi all,
does anyone knows if frameworks like UIKit or iAd can be integrated in Qt Creator?
I want to use them in a Qml app.Thanx,

Hi,
What do you mean by integrated in Qt Creator ? Write your software to use Apple's frameworks ?
-
Yes. For example add in the *.pro file something to include the frameword, e.g.g the iAd.framework and then in the *.h and *.cpp file
to include the header and use the class objects.Even in the qml it would be interesting...

I use iOS frameworks in Qt projects and it's very easy ... but you cannot use them from .cpp files because they are objective-C classes, so you have to add a .mm file to the project.
And for use them in QML it's very easy: create a QObject subclass, implement it into an .mm file where you wrap any method you like of the framework and register the QObject for use it in QML.In .pro files I use the following directive:
@This flag is necessary otherwise you get an link error
I open a bug reports for that
QMAKE_LFLAGS += -F/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/System/Library/Frameworks
Add the framework you need
LIBS += -framework AdSupport -framework StoreKit
the objective sources should be put in this variable
OBJECTIVE_SOURCES += backend_ios.mm

Then the quickest is to take a look at QtMacExtras, you'll see how it's setup to work with frameworks.
You can't write Objective-C/C++ in qml files. You'll have to create a derived QObject class that you will use to call native functions/methods/etc...

Thank you guys!!!
I will check these and come back if I have still problems...Thanks a lot!

Hi Gianluca and SGaist,
as I am new into this field I would need some more help:
To Gianluca:
Could you please post an example of such a subclass implementation in the *.mm file? Also what I have to put in the backend_ios.mm?To SGaist:
Could you also please post an example of creating a derived class?Thanks in advance for your guidance!

Take a look at the QtMacExtras module and the cocoa platform plugins, they show it nicely
