Push Test

I was able to setup my server and mobile device (iPhone and iPod touch) to make the push notification service working. I had to send a binary data packet over SSL/TSL connection and the APNs doesn't even tell me anything back, so it was very difficult to debug the system. So if you need someone to setup the push notification, you can contact me.

UIAlertView is a convenient method to notify users with a short message and a couple buttons. However, it could be, actually quiet commonly, a little tedious to open up one. Just like this.

UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Message"
        message:@"Data was received, but could not be properly interpreted"
        delegate:self cancelButtonTitle:@"Dismiss" otherButtonTitles:nil];
alert.tag = AlertInvalidJSON;
[alert show];
[alert release];

So, I decided to make a very simple macro so that I don't have to type all that. (Thanks to C)

#define Alert(tag, title, msg, button, buttons...) {UIAlertView *__alert = 
[[UIAlertView alloc] initWithTitle:title message:msg delegate:self 
cancelButtonTitle:button otherButtonTitles:buttons];[__alert setTag:tag];
[__alert show];[__alert release];}

Now it takes less time to type, and is easier to read.

Alert(AlertInvalidJSON, @"Message",
    @"Data was received, but could not be properly interpreted",
    @"Dismiss", nil);

Just remember the following two steps:

1. Get an instance of UIAccelerometer, using UIAccelerometer.sharedAccelerometer method, and specify the update interval and the delegate target.
2. Implement UIAccelerometerDelegate within the delegate target; for example, a view controller.

Apple finally approved CQube last sunday night. It took exactly seven days to go though the review process.

I was kind of impressed that CQube got about 100 download hits internationally at the first day of release.

I really hope CQube keeps being spread out at this pace or faster! I'm planning to launch the full-featured game within two months (on this May), if the classes are nice to me. You know, I'm a full-time college student.

So, those of you who are waiting for the full version, please be patient. Whatever you imagine, you will see more than that.

To display your application artwork within iTunes, save a 512x512 .png at the root of your app bundle prior to building. Name the file 'iTunesArtwork'.

You probably have read this from the iPhone developer program user guide. Are you having some trouble with setting a 512x512 PNG image for your application's artwork? Did you name your artwork file as iTunesArtwork.png?

Do not name your file as iTunesArtwork.png. It must be iTunesArtwork. Without extension.

When I was getting this message, I checked console messages in the Organizer.

Doesn't seem useful unless you know how this tiny device exactly works. I wasted a couple hours to play with entitlements and other stuff that might be related to this issue. There was no luck. Then I finally figured out what I did wrong. You probably made a same mistake just like I did.

Didn't you put the whole App ID that you copied from the iPhone developer portal? Don't do this!

Put

com.domainname.appname

Instead of

XXXXXXXX.com.domainname.appname

I should've read the manual more carefully ;-)

BOOM!

If this is not your case, well, you might want look for other solutions. Good luck.
