Hi all,

my app is in landscape mode, and I have achieved this via the Sparrow ways of rotating and moving things that are added to SPView.

I've got iAds working and showing up by creating AdvertViewController which is a UIViewController, and adding the view (advertViewController.view) to a UIView which is created and owned by the app delegate and added to the nativeview/spview.

I rotated and moved the UIView so it lines up with the top of the screen and looks landscape etc.

The only problem is, if I click on the displayed iAd, and the close the iAd again, the device orientation goes all messed up, and the status bar orientation switches back to portrait mode.

Anyone else seen this kind of behaviour or know what to do?

Thanks...

I have decided I definitely need to get a rootViewController working with the appdelegate for this (UIViewController).

I believe I have got this working, with some help from a forum member here's post 3 months ago (TrahDivad).

However, I notice that it is strongly advised NOT to rotate the SPView for performance reasons.

I have used this code:
CGRect viewFrame = CGRectMake(0.0f, 0.0f, 1024.0f, 768.0f); SPView* view = [[SPView alloc] initWithFrame:viewFrame]; [self setView:view];
I now don't have to rotate the subviews (SPSprites etc) 'cos it is all done at the root level (I sent device orientation landscaperight).

So, I haven't actually manually rotated the SPView, it just will be rotated by virtue of the entire application rootViewController being rotated.

Is that ok?

Hm ... even if the SPView is not rotated directly, but through one of its parents, you'll still have the performance penalty. However: as far as I know, the performance problem with rotating OpenGL-Views was removed at least with iOS 5, perhaps even 4 -- perhaps you can google/find more information on this. And even on older versions: if the performance is good enough, I'd go the simple way and leave it at that.

Hi,

yeah I took a look, and found this article:

http://developer.apple.com/library/ios/#documentation/3DDrawing/Conceptual/OpenGLES_ProgrammingGuide/WorkingwithEAGLContexts/WorkingwithEAGLContexts.html

It's all in there, apparantly PowerVR SGX-equipped devices (iPhone 4+, iPad and iPod Touch 4th gen) and iOS 4.2 and later should be fine.

So, one of my test devices is an iPod 3rd gen (with iOS 4) so if it's fine on there, then I shall consider it fine for release.

I support minimum iOS 4.0 anyways these days.

Just for reference, iPhone 3GS also has an SGX chip.

Ok,

so here's what I found.

Version 1 iPad with iOS 5x runs great, super fast in fact!

iPhone 4 with iOS 4x runs great too.

iPod Touch (late 2nd gen/early 3rd not sure) with iOS 4.2 noticeably lags when displaying upwards of 12 - 15 sprites on screen at the same time.

Since this doesn't happen too often in my game, and due to the nature of how things work, this is acceptable and I shall proceed.

This is just using a rootViewController and adding the SPStage to that view instead of the scaffold method.

iAds work great in correct orientations too!

Another tip for anyone implementing something similar, reducing the framerate from 40fps to 30fps also helped with the iPod Touch performance issue too, with no noticeable lag, and still looks great on the iPhone 4

In PenguFlip, I had the same problem; on the first iPhone generation, I let it run with 30 fps; on later generations, with 60 fps.

Here is the code that allows you to do so:

- (int)fpsForCurrentDevice
{
    UIDevice *device = [UIDevice currentDevice]; // see below
    NSString *platform = [device platform]; // declared in Utils.h
 
    int fps;
    if ([platform rangeOfString:@"iPod1"].location == 0 || [platform rangeOfString:@"iPhone1"].location == 0)
        fps = 30;
    else
        fps = 60;
 
    return fps;
}
 
// adding an easy to use category to "UIDevice"
@implementation UIDevice (Hardware)
 
- (NSString *)platform
{
    size_t size;
    sysctlbyname("hw.machine", NULL, &size, NULL, 0);
    char *machine = malloc(size);
    sysctlbyname("hw.machine", machine, &size, NULL, 0);
    NSString *platform = [NSString stringWithCString:machine encoding: NSUTF8StringEncoding];
    free(machine);
    return platform;
}
 
@end
