App – Word Connect (Lite & Sale)

kooworx — Fri, 18 Sep 2009 07:29:58 +0000

Connecting letters and making words in a new way, it’s full of fun! Here comes the full version of Word Connect – an addictive word game!

The rules are simple, you just need to use the given letters to make words, as many as you can, but the letters must be placed in a single line. The words you made should have the minimum size of 3 letters. (In the Four Limit game type, you must made words with at least 4 letters)

Each round you’ll get seven letters, each letter must be inserted into the line. Once you’ve made a word, the letters that made up the word will be lighted up. A game round will be ended when you inserted all the seven letters, then the words you made will be calculated. Try to make more words in a round. If you lighted up all the seven words, you’ll get score bonus.

In the full version, there are three types of Word Connect game included:

1 – Endless. Play as long as you can, try to beat the highest score!

2 – 50 Rounds. Play for 50 Rounds to see how much you can get.

3 – Four Limited. You must made words with at least 4 letters, this is endless, too.

One thing more. There is an automatic saving function implemented. So you can just close the game and continue to play next time. But when you continue playing a saved game, the saved progress will be cleared, new progress will be saved when you pass current round.

So, let’s make some words!

The full version features:
————————–

* Online global leaderboards and achievements plus Facebook and Twitter integration, courtesy of OpenFeint.
* Four leaderboards to challenge.

Prevent iPhone From Sleeping

kooworx — Thu, 30 Jul 2009 13:00:46 +0000

If your game do not require the user to interactive with the touch screen, say for example you only use accelerometer for moving your sprite. You’ll notice that the iPhone will go sleeping after a while. We don’t like this, so, you can add this to prevent it from sleeping:

 Objective-C |   copy code | ?  
1 [UIApplication sharedApplication].idleTimerDisabled = YES;

That will be all.

imageNamed and imageWithContentsOfFile

kooworx — Tue, 28 Jul 2009 04:09:36 +0000

In my last project, I used more than 100 images. It’s OK while I was testing it on the simulator. But when I uploaded it onto the device, it crashed all the time. I check the crash log, it showed as “low memory”.

I used this to load image:

 Objective-C |   copy code | ?  
1 singleImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"test.jpg"]];

When I run it with Instruments, I noticed that the use of the memory were increasing very fast and seemed to be not released. That's why the app crashed and through out a 101 error. It looks like that the imageNamed will cache images in the memory and only release the memory while the app terminate. Then I use imageWithContentsOfFile for a replacement of imageNamed:

 Objective-C |   copy code | ?  
1 NSString* str = [[NSBundle mainBundle] pathForResource:@"test.jpg" ofType:nil inDirectory:@""];
2 singleImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithContentsOfFile:str]];
3

The problem solved! You can see the snapshot of Instruments below, the memory were released when I changed to another category.

The imageWithContentsOfFile might be slower than imageNamed, but it is worthy to use it.

To Be Compatible With OS 3.0

kooworx — Sun, 26 Jul 2009 07:53:48 +0000

While, as we all know, OS 3.0 has been installed or upgraded on most of the iPhones, but, there are still a lot of iPod Touch not upgraded. So, by now, we still need to develop our apps based on the OS 2.2+ then try to make it compatible with OS 3.0.

When we test our apps on OS 2.2+ and OS 3.0, we found out that some thing different in the two platforms, so if your want the same code to be built for different OS, here is the trick to do it.

 Objective-C |   copy code | ?  
01 - (void)viewDidLoad {
02  
03 #ifdef __IPHONE_3_0
04 	NSInteger offset = -40;
05 #else
06 	NSInteger offset = 0;
07 #endif
08  
09 	/* Your code here */
10  
11 	[super viewDidLoad];
12 }

You can notice that we used pre-processor directives for the conditional compilation. But there is still a problem: we have to build two binaries for the different OS. What if we want to build only one binary that can be compatible with both platforms?

This code will do it for you:

 Objective-C |   copy code | ?  
01 - (void)viewDidLoad {
02  
03 	NSString *version = [[UIDevice currentDevice] systemVersion];
04  
05 	int offset = -40;
06  
07 	if ([version isEqualToString:@"2.2"] || [version isEqualToString:@"2.2.1"]) {
08 		offset = 0;
09 	}
10  
11 	/* Your code here */
12  
13 	[super viewDidLoad];
14 }

This code will detect the systemVersion of the OS, then we can get one binary to run on different OS.

For another usage, you can use this:

 Objective-C |   copy code | ?  
1 float version = [[[UIDevice currentDevice] systemVersion] floatValue];
2 if (version >= 3.0)
3     {
4     // iPhone 3.0 code here
5     }

Hi folks, this is the very first post in this newly created blog. We’ll put some stuff about what happened during our development of iPhone applications.

 Objective-C |   copy code | ?  
1 NSLog(@"Hello world from kooworx");

1	NSString* str = [[NSBundle mainBundle] pathForResource:@"test.jpg" ofType:nil inDirectory:@""];
2	singleImageView = [[UIImageView alloc] initWithImage:[UIImage imageWithContentsOfFile:str]];

01	- (void)viewDidLoad {
02
03	#ifdef __IPHONE_3_0
04	NSInteger offset = -40;
05	#else
06	NSInteger offset = 0;
07	#endif
08
09	/* Your code here */
10
11	[super viewDidLoad];
12	}

01	- (void)viewDidLoad {
02
03	NSString *version = [[UIDevice currentDevice] systemVersion];
04
05	int offset = -40;
06
07	if ([version isEqualToString:@"2.2"] \|\| [version isEqualToString:@"2.2.1"]) {
08	offset = 0;
09	}
10
11	/* Your code here */
12
13	[super viewDidLoad];
14	}

1	float version = [[[UIDevice currentDevice] systemVersion] floatValue];
2	if (version >= 3.0)
3	{
4	// iPhone 3.0 code here
5	}
