Lack of the 'maScreenOrientation' syscall implementation on iPhone runtime

That was me hoping for 3.0. In any case, it is done for iOS, almost done on Android and waiting its implementation on Windows Phone. And because of these, it won't get out on 3.0, but on a 3.0.1 version. In any case, it is one of the top priorities. Anyway, I was wrong and it's past the date I thought you'll have access to it.
Sorry,

Hi Ovidiu,

I've upgraded my mosync to 3.0.1 however the orientation for ios still does not work. Looking at the maapi.h i see the following comment :

/**

 * Set the screen orientation.
 * Currently implemented only on Android.
 * @param orientation One of the \link #SCREEN_ORIENTATION_LANDSCAPE
 * #SCREEN_ORIENTATION_PORTRAIT #SCREEN_ORIENTATION_DYNAMIC \endlink
 * constants.
 * @return \< 0 on error.

 */

IOCTLDEF int maScreenSetOrientation(int orientation) {
return (int) maIOCtl(139, orientation, 0, 0);
}

Does this mean that its still not included in 3.0.1 and (hopefully) scheduled for 3.1 ?

Hi,

For iOS and WP7 check this out:

/**
* Set supported screen orientations.
* Currently implemented on iOS and WindowsPhone 7.1.
* @param orientations A bitmask consisting of flags describing the supported screen orientations.
* The bitmask can be created using \link #MA_SCREEN_ORIENTATION_ MA_SCREEN_ORIENTATION \endlink
* values.
* @return One of the next constants:
* - #MA_SCREEN_ORIENTATION_RES_OK
* - #MA_SCREEN_ORIENTATION_RES_NOT_SUPPORTED
* - #MA_SCREEN_ORIENTATION_RES_INVALID_VALUE
*/
int maScreenSetSupportedOrientations(in int orientations);

this is because on Android this is prety dificult to takle while the same thing can be said of maScreenSetOrientation regarding iOS and wWP7

Thanks for your quick reply.

So to see if I understood correctly, I simply call the method maScreenSetSupportedOrientations as follows

maScreenSetSupportedOrientations(
MA_SCREEN_ORIENTATION_LANDSCAPE_LEFT |   MA_SCREEN_ORIENTATION_LANDSCAPE_RIGHT);

and the orientation will be magically landscape ?

Not quite :)

maScreenSetSupportedOrientations(
        MA_SCREEN_ORIENTATION_LANDSCAPE_LEFT |             
        MA_SCREEN_ORIENTATION_LANDSCAPE_RIGHT);

This will tell the OS that the only orientations allowed are the 2 landscapes. Therefore, if the device is rotated to portrait for example, nothing will happen, but if the device is rotated from landscape right to landscape left, the change will happen. So this might not be what you want, i.e. to change the orientation through code no-matter the orientation of the device. However, we have this in mind and we've planned a meeting where to decide how to harmonize the setOrientation among the different platforms we support to date (especially Android, iOS and WP7)

That is exactly what I'm looking for. Forcing the orientation to landscape mode irrespective of the device's true orientation.

Many thanks!

I can't promise that it'll be done for 3.1 but you can help us prioritising by asking for it: http://www.mosync.com/content/put-all-new-feature-requests-mosync-issue-tracker :)

cheers

will do just that
