Recording Audio

Sat, 05 May 2012 06:31:48 -0500

Hi!
I am going to make something like assistant for iPhone (I have server with DB of responses) but I need to use it with Google Chrome Speech API. Google Chrome Speech API uses 8000 or 16000 bitrate FLAC file. How can I record in this format with needed bitrate? I am new at Objective-C and iOS programming.
Thank you.

Cloud based database app for multiple users

Thu, 03 May 2012 17:53:37 -0500

I'm working on research for a new iOS app and I'm having trouble finding information. So, I thought I'd ask you guys if somebody can point me in the right direction.

As the title suggests: I'm interested in creating a database style app, preferably a core data app, that allows for multiple users to work on the same database simultaneously. Preferably, I'd like it to work somewhat like the shared calendars do in iCal. All users can review and edit the database and the database refreshes occasionally to reflect changes made by other users.

I don't want to have to set up a 'master server' for all the users to be sending their data to, and from what I understand, iCloud is not suited to this because it doesn't support sharing. I've started looking into Dropbox...

Does anybody know of any articles or services I can look into? Or even if somebody can help me find the right terminology for what I want to do so i can search for myself. Thanks!

Header, Input and Units

Sun, 29 Apr 2012 00:53:32 -0500

I am very new to iOS programming and I am trying to get started on making an App for scientific calculations but cant seem to find how to do a simple pull-down menu that will allow a user to assign a unit of measurement to a value they just input.

I will have many inputs, typically four per row. Each input will have a title/header text then below the title/header there will be an input block and, the part I am having the most problem with, a pull-down menu that will allow a user to select a unit of measurement, as an example, inches or millimeters. When the selection is choosen I would like the menu to shrink and display the selected value. Wondering if someone can lead to an example?

I would like the selected unit of measurement to look like the header text meaning no frame or any indication that the item is a pulldown menu because sometimes some units will not have a unit of measurement because they could be a percentage where I would have the percent symbol below the input. The idea is to have a very uniform display of headers, input blocks, and units.

I have done this entire app on an android and trying to make the same thing for iOS and find it hard to get started. ANy guidance is greatly appreciated.

How can you set a different output name for different build configuration in xcode?

Thu, 26 Apr 2012 12:56:27 -0500

Hi All;
I'm new to Mac and Mac development. The company i work for has developed an application in Windows using the Qt framework and VS2010. I am now working on importing this project over to the Mac environment. We will be using Xcode to finish the dev/import and build process. Some of our projects have a different name based on the build configuration. IE: the debug configuartion would build xxxx_debug.xxx and the release configuration would build xxxx.xxx.
How can you accomplish this in Xcode?

PaintCode - a vector drawing app that instantly generates Objective-C drawing code

Fri, 13 Apr 2012 12:13:34 -0500

Designing an attractive, resolution-independent user interface is difficult, especially if you have to program your drawing code. PaintCode is a simple vector drawing app that instantly generates resolution-independent Objective-C drawing code for both Mac OS X and iOS.

Website:
http://www.paintcodeapp.com/

App Store link:
http://itunes.apple.com/us/app/paintcode...570?mt=12#

You no longer have to tweak and recompile your drawing code over and over again to achieve the desired result. With PaintCode, a graphic designer with no programming experience can draw beautiful controls, icons and other user interface elements, and the app automatically generates a code that is equally beautiful.

iGipf - Developing an iOS game in 2 weeks

Wed, 04 Apr 2012 19:38:04 -0500

We all remember those "How to learn C++ in 21 days" books:

Many people are probably skeptical about this idea, but (as we’ve already been into the future) there is no reason to doubt it? Before we delve into the specifics of our programming venture, here is a brief introduction to our team. We are a couple of programmers with no claim (oh, really?) to fame like Angry Birds and, moreover, with very little experience in iOS or GameDev in general. Roughly speaking, for us, this project is being undertaken as both a challenge to ourselves and, ultimately, for the pure fun and experience even if little can be achieved (oh, really?) in the end.
Now that you know at least a little more about us than Google can tell you, let’s talk about the rules for this endeavor. “Two weeks are enough for every project” was a statement made by one of us (let’s call him Bill…No, Bond is better) in a Skype call late one night. “Okay, but maybe…” was the reply that was abruptly cut off by “No buts or maybes.” Well, OK, if you say so! Of course, we could spend these weeks investing time in our families, working, taking care of the fate of humanity, or any number of other noble pursuits. Yeah, right! If you’ll buy that, I have a bridge to sell you. If we weren’t doing this project, the honest truth is that we’d be playing Starcraft, wasting time on Facebook, or just drinking beer.
Anyway, back to the rules, which have been set:
Two weeks of deeply intensive development is enough if you think about it. After all, 2 * 7 * 24 = 336 hours, which translates, via the following sophisticated math (336/8 *7/5 = 58.8), into nearly 59 calendar days or 2 whole months! Clearly the math justifies the time limit (looks like there might be a trick somewhere… But millions of managers can be wrong!). And, quite seriously (this is a serious post; honestly), our programming practices prove that the best way to raise the priority of any given task is to decrease the time limits for completing it. So, exactly two weeks (“exactly” means two weeks plus an extra two weeks depending on the situation). Rule 1 is complete!
Work on other rules later.

OK, now that the time limit is set, we must decide what we should write. After an objective evaluation of our capabilities (who are we trying to fool?), we decide not to write a 4D-shooter with RPG (or BDSM) elements and multiplayer capabilities for 20,000,000 simultaneous players. However, after some discussion, we do think that having a simpler multiplayer option our game is a grand idea.

As a basis, we took the game called GIPF, as there is nothing in the AppStore (and not planned, as we see). We decided to change the rules of the original game a little bit to make it even simpler to play, to ensure that it is not an exact copy of the original game, and to make it even more fun. In short, it will be a logical game with rules a bit more complicated than Tic-tac-toe and with a bit less need for strategy than chess. This seems like a good way for roughly 67 to 68% of Americans to spend their time. This number of users is calculated using extremely strict formulas with basic expectations about the number of sales of the application, at the price of $149, that are needed in order for us to purchase an island in the Mediterranean Sea on which to live and carry on about our programming. These numbers can be slightly reduced (~1,000 fold) in case we decide that money is not the main goal of our lives.

Our plans for the day:

High-level architectural design of the application
List of tasks and time limits
Make decisions about the supported platforms and iOS version

Day 2.

Today there won't be any jokes because the serious development process has started. Let's begin on a positive note: we still have some development time left and our time milestone hasn’t passed yet. While being serious, we should look at what our current decisions are:
We will use Cocos2d as the graphical engine ([URL="http://www.cocos2d-iphone.org/"]http://www.cocos2d-iphone.org/[/URL])
The minimum target iOS version will be 4.2 or 5.0 (there are some good reasons). This decision has been made after analysis of the iOS statistics for August 2011 (http://www.marco.org/2011/08/13/instapap...ts-update)

Initial architecture thoughts:

Model: low level

We thought that when it comes to AI and processing tons of data, any overhead would be multiplied by a large factor (maybe several thousand fold). As a result, we decided to write the low-level (everything that is connected with data representation and the board state) in pure C.

The two base classes are:

* BoardInfo – This contains data that does not change during the whole game: board parameters: width/height, field structure, etc.

* BoardState – This contains data that changes during the game: current set of pieces on board, number of pieces in reserve for both players, etc.

Our AI thoughts are based on evaluation of a large quantity of board states (for example, if we use Alpha-Beta pruning), so we absolutely need to use simple 'memcpy' to copy them and the fastest operations to operate with them. That's why the data organization above and pure C were chosen.

Model: high level

Here comes Objective-C and high-level wrappers of the two classes discussed above. AI uses low-level model only to make decisions about what is the “best move.” In all other cases, high level model objects are used (even to make the move, which was just evaluated using low-level structures only).

HexBoardGame – This class contains inner variables of type BoardInfo that do not change during the game. It also contains an inner variable of type BoardState, which is changed every turn, as well as initialization functions. Everything that is needed to create a game skeleton from board parameters (BoardInfo) and changing board states (BoardState) is also included in this class.

GipfBoardGame – This contains the specific implementation of HexBoardGame for iGipf rules. It expands HexBoardGame with such things as moves with pieces shifting (see the rules), row removal (see the rules), etc.

Controller
Here, we think everything is clear.

Views
Everything is even clearer here. CCScene -- is a class from Cocos2d.

Conclusion:
Enough for today. These drafts helped us to understand what we are going to implement and how to start the basic coding routine. The next interesting step will be AI experiments for which we need a proof-of-concept; but we'll talk about that.

Key Value Coding

Mon, 02 Apr 2012 23:42:32 -0500

I'm another beginner trying to get my head round Cocoa and its intricacies. I was reading DeVoe's "Objective-C". In the section on Key Value Coding there are some examples of setValue:forKeyPath:. Somehow, try as I might I cannot get it to work.

The following is the code -

Code:

//

// Bar.h

// UsingKVC

//

// Created by Stephen Ng on 2/04/12.

// Copyright (c) 2012 Nutek. All rights reserved.

//

#import 

@interface Bar : NSObject

{

NSArray *array;

NSString *stringOnBar;

}

@property (retain,nonatomic) NSArray *array;

@property (retain,nonatomic) NSString *stringOnBar;

@end

Code:

@interface Foo : NSObject 

{

Bar *bar;

NSString *stringOnFoo;

}

@property (retain,nonatomic) Bar *bar;

@property (retain,nonatomic) NSString *stringOnFoo;

@end

Code:

//

// Bar.m

// UsingKVC

//

// Created by Stephen Ng on 2/04/12.

// Copyright (c) 2012 Nutek. All rights reserved.

//

#import "Bar.h"

@implementation Bar

@synthesize array;

@synthesize stringOnBar;

@end

@implementation Foo

@synthesize bar;

@synthesize stringOnFoo;

@end

Code:

//

// main.m

// UsingKVC

//

// Created by Stephen Ng on 2/04/12.

// Copyright (c) 2012 Nutek. All rights reserved.

//

#import 

#import "Bar.h"

int main (int argc, const char * argv[])

{

@autoreleasepool {

Foo *foo = [[Foo alloc] init];

[foo setValue:@"blah blah" forKey:@"stringOnFoo"];

NSString *string = [foo valueForKey:@"stringOnFoo"];

NSLog(@"string: %@", string);

[foo setValue:@"The quick brown fox" forKeyPath:@"bar.stringOnBar"]; 

NSString *string2 = [foo valueForKeyPath:@"bar.stringOnBar"]; 

NSLog(@"string2: %@",string2);

}

return 0;

}

--------------

string2 is NULL!

I do not understand this. I understand that when using @property all the code becomes KVC compliant. Yet it seems the key path does not work.

Any help in learning this "beast" will be much appreciated.

Thanks.

Stephen

New to iOS development. Where do I start?

Sat, 31 Mar 2012 13:35:02 -0500

Hello all!

First time in this part of the forum

I'm in need of some direction and guidance. A quick background; I'm very solid in all the basics (HTML, CSS) and know a bit of php, and have messed a little with Ruby on Rails in the recent past. Very solid with wordpress as well and work with it on a daily basis.

The things that I haven't even come close to touching and regret not doing sooner is actual software programming and engineering. I have no C, Objective C, etc experience. This is something I've really wanted to learn, understand and become very proficient at for some time now, and there is no time like now.

There's a massive amount of resources, tools, tutorials, instructional etc out there, this I know. But I really have no idea where to start. What language do I dive into, resources and so on. The end goal is to become a very solid app developer, but it won't come easy or quickly, I'm not at all under the mindset that I'll be in the app store within weeks or months. I've spent the last 10 years of my life in e-commerce, seo, sem, marketing, and simple programming world, I know the task that sits before me.

So guys...where do I start? Any advice is very much appreciated!

Hello, I am new to the forum.

How is everyone doing?

Wed, 29 Feb 2012 18:07:58 -0600

Hello folks, I was just passing by and thought to say hello to my former site. Hope everyone here is well. As for me, I'm trying to return to some coding. Don't laugh, but I'm starting with Pascal... pretty much where I left off with 20+ years ago in college plugging away on a Vax system. lol (While the other nerds played MUDs.) I'd like to poke around with Python as well and at some point settled down with Objective-C. Anyways, hope all is well with you all.

Cheers

NSMutableArray ...

Tue, 13 Dec 2011 17:28:49 -0600

Hi, I'm very new to Objective-C and having hard time with NSMutableArray sorting...

Code:

...

//2d array

// [2 8 14]

// [1 3 22]

// [7 9 13]

NSMutableArray *twoD = [[NSMutableArray alloc] initWithCapacity: 3];

  [twoD insertObject:[NSArray arrayWithObjects: @"2", @"8", @"14", nil] atIndex:0];

  [twoD insertObject:[NSArray arrayWithObjects: @"1", @"3", @"22", nil] atIndex:1];

  [twoD insertObject:[NSArray arrayWithObjects: @"7", @"9", @"13", nil] atIndex:2];

I am trying to sort the entire twoD array to look like
[1 2 3]
[7 8 9]
[13 14 22]
I looked at using sortedArrayUsingSelector: @selector(compare but that pertains to if i have a selector specified in my array correct? Thanks for the assistance.

Life test application on iPhone

Sat, 29 Oct 2011 05:12:46 -0500

Do I have to make a paid account in the App Store to deploy my application to could download it on a real device to test in life? I already have a developer account and it is paid account for my company but I need to test my application life on a real device not on the simulator in the xCode. What if I wanna make a special application to myself only and I want it to be on my iPhone not public?
