[Interest] Qt 5.2 basic example on iOS not working, what am I doing wrong?

[Turunen Tuukka]

Hi Thomas,

The examples problem was very unfortunate, I am sure you are not the only one who hit it. It is already fixed and becomes available when Qt 5.2.1 / Creator 3.0.1 are released.

Yours,

Tuukka

Ok... so now I finally have it working :-) Although there are still a couple of small issues...

First of all, I noticed that regardless of what I selected on the combobox in the Examples browser, it always loaded the examples from the "clang_64" folder. So I tried loading the examples directly from the .pro files under ios/examples in the Qt installation dir, and then it worked! All examples I tried this far worked nicely :-D

It would seem that there is a little bug in the examples browser then. Probably worth fixing, since I can't imagine that I am the only one trying to run the examples from the examples browser :-) I can make a bug report on it.

The next issue is my "Hello World" app... And that still baffles me. I created a new one, identical to the first one (copied the source files from the first test). The only difference was the name, and now it suddenly worked! Next I tried setting a different target name in the .pro file for the first project, and then that too worked!

Obviously there must be some bogus state cached somewhere that I can't get rid of. I've tried deleting the shadow build directories of course, as well as the $HOME/Library/Application Support/iPhone Simulator, but still no luck. As long as I call the app anything but QtMobileTest it works, but that particular app name is apparently banned forever...

Oh well, I can live with that, but it still is weird...

First of all It appears that you need to actually compile something in XCode before you can use the command line tools from Qt Creator. I just made a dummy iOS application from a template. The first time I compiled it in XCode I got a dialog box asking me if I wanted to enable "Developer Mode" or something on my Mac. After doing this, and going back to Qt Creator, my Qt test app worked!

This was with the Qt for Android and iOS package: http://download.qt-project.org/official_releases/qt/5.2/5.2.0/qt-mac-opensource-5.2.0-android-ios-x86_64-offline.dmg

Then I tried the Qt Examples again, but it still won't compile. After a bit of googling I found that this looked very much like the following bug:

https://bugreports.qt-project.org/browse/QTBUG-35485

But this is supposed to be fixed in Qt 5.2.0. So I thought I'd do a reinstall of the Qt package. This time I go back to the iOS only package, i.e this one:

http://download.qt-project.org/official_releases/qt/5.2/5.2.0/qt-mac-opensource-5.2.0-ios-x86_64-offline.dmg

After installing it, I make sure that I have selected "Qt 5.2.0 for iOS" on the combobox in the examples browser and try compiling a random example tagged with ios. Same problem, no Qt headers can be found. Exactly the same behavior as described in the bug report.

And on top of that, my own simple "Hello World" app stopped working in the simulator again :-(

Now, I'll try the online installer to see if that works better, but right now I'm starting to lose faith a bit :-)

http://download.qt-project.org/official_releases/qt/5.2/5.2.0/qt-mac-opensource-5.2.0-ios-x86_64-offline.dmg

This package installed kits for Mac Desktop as well as iOS device and iOS simulator.

This is so weird... I guess other people has this working, right?

the examples that are installed with qt, and which are tagged with "ios" in Qt Creator. None of these will even compile when targeting the iOS simulator. None of the Qt headers can be found when compiling for iOS..

Uhm... This might sound stupid, but which Qt binary package did you install? There are distinct ones for "Mac Cocoa" (desktop) and "Mac iOS" development on the download page...

Cheers,
 Oliver
