Generating variable frequency tones
Hi, I'm looking for some way to generate a tone that resembles the sound of an instrument. I need precise control of the base frequency (pitch). I'm wondering what would be the best way to generate it on an iPhone. Store a file with a know frequency and resample it to the desired frequency? Synthesize a tone by calculating a bunch of sines? Doing some FFT trick on a file? If someone can give some insight into what would best fit the H/W available it would be grateful.

Re: Question about architecture
Sure Greg Guerin, I couldn't agree more. I have 10 years of experience in software development and this is the process to be an expert in anything, in cocoa it will not be different. But my approach to learn any new language is read at least three books entirely before do any serious development (commercial). It worked very for me and make me much more productive to solve specific bugs that I never experienced before. My question is more related to Cocoa specific things like Laurent answered. My idea to separate the app in diferent nibs is the same principle of single responsibility and make my view layer easier to maintain. For example, with a custom nib my Controller for that specific view in that nib can do less things than handle all view in the same window. Make sense or I should create a custom view (and a different controller for that view) and keep everything in the same nib until I need speed up the launch? Thanks.

A/B testing
I have a relatively simple game, and I wanted to test some UI elements, to see which is more popular and useful for customers. Does anyone have a practice of setting up a testing harness in their app, so they can readily show different versions to different users, and report back on those metrics? I've done this on web sites, but, seems near impossible or at least very difficult to do it for the iPhone. What I'm thinking is: - use some kind of Device ID naming system to display certain elements and functionality - check back to a server and log the deviceID/version and somehow track that to emails from the user (populate the deviceID in the message), or other comments.

Re: Question about architecture
One of the main reason to split different views in different nibs is that it speeds up launch time. If all your views are in the same, "MainWindow" nib, then all those views need to be instantiated and their outlets connected when your app starts. So, the idea is to segment those views in different nibs that you can load on demand only when you need them. For example, if you have a preferences window, you can put it into a separate nib. That way, it's not loaded until the user choose the preferences. -Laurent. -- Laurent Daudelin AIM/iChat/Skype:LaurentDaudelin http://www.nemesys-soft.com/ Logiciels Nemesys Software laur...@nemesys-soft.com On Sep 9, 2010, at 12:58, Daniel Lopes wrote: > Thanks Richard, actually I already read Hillegass book.

Phone lock/Apple sounds
Hi all, My iPhone application continuously pings a back-end server to check for new documents. If a new document is found an alert is triggered which consists of a dialogue and sound alert. If the phone is locked then neither of these events occur, which is undesirable. With a bit of googling I have discovered you can disable the standby timer, which helps but doesn't cover the use case when a user locks the phone manually. Is there any way to allow the alerts to continue to fire even when the phone is locked? Obviously Apple achieve this with calls/messages etc but perhaps it is not possible with 3rd party applications? I also have a query about using Apple's alert sounds. Firstly how would I get hold of for example the top three Apple alert tones (i.e. Tri-tone, Chime and Glass). Secondly, are these sounds copyrighted or are you able to use them in a 3rd party app. Many thanks in advance, Dan ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Re: core data structure?
When you say a product can link to more than one order, then I assume you use an array to store the orders. Why not just creating an array of dictionaries, where in each dictionary you set the order, the number of products, and possibly other information. This way when you want to know how many products are in an order, just go serch for your order in the array of dictionaries and get it. This is just to clarify that you haven't to search for strange things. This is not performant - it's just to help you figure it out. -- Luca C. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Animating the view layer
Hi Everybody I need to bring the ripple effect animation in iphone that is present in widget application when you drop a new widget. I tried posting in various forums including apple forum I cant find the answer for it. I hope you guyz can help. The following is the code which I used for the animation. UIButton *Button1=[UIButton alloc] init]; Button1.frame=CGRectMake(0,0,50,50,50); [baseUIView addSubview:Button1]; CATransition *animation= [CATransition animation]; animation.timingFunction=UIViewAnimationCurveEaseInOut; animation.duration=1.0f; animation.type=@"rippleEffect"; [[BaseUIView layer] addAnimation:animation forKey:animation]; If I use the above code I get the ripple animation for the entire view . But I just need to animate around the button. So I tried animating a view formed around the button and adding it to the base view I`m not getting the animation.

Yes, but before you use transient attributes, be sure to study all their limitations given in the Core Data Programming Guide. I am not a fan of transient attributes, as you can read here: http://www.cocoabuilder.com/archive/cocoa/237109-only-one-reason-to-ever-use-transient-properties-in-core-data.html?q=only+reason+transient+attributes#237109 http://www.cocoabuilder.com/archive/cocoa/234791-core-data-fetches-transient-properties-nspredicateeditor-sadness.html?q=only+reason+transient+attributes#234899 Unless you have a user base of millions, or are a fantastic programmer, it's hard to beat today's hard drive prices of less than a dollar per gigabyte. So the smartest solution is often to just leave the "unnecessary" attributes in the persistent store, and start on your next project. Another alternative is to add a regular instance variable to your managed object. Regular ivars still work. Or, in this case, it appears that calculating them as needed and implementing +keyPathsForValuesAffectingX to make them KVObserveable would work and get you home on time. ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Question about architecture
Hello, I'm learning Cocoa and Objc and enjoying a lot, especially because my background is in Ruby and both languages are basically the same thing except for the syntax. But what I don't understand very well and neither find good guidelines is how architect my app. I'm doing my studies in a small pet project but I would like to make that project as close as possible to a real polished commercial app. The goal of the app is access my snippets in gist.github.com and manage that with ability to search, add, edit, delete and some shortcuts (I also want to put an icon in menu bar). Today I going with that UI: http://cl.ly/2JYu On the left side of Splitview I have a Custom View for the header (because I want a diferrent background) and TableView where I will display all my gist snippets. On the right side another Custom View for the header and a TextView. My idea for organization is separate the entire content on the left side in a new Nib called sidebar and set the FileOwner to a controller in Window Nib. Also do the same thing for the right part of the Split View. That behavior the behavior to separate big "components" of the UI in diferent nib's is right? Create custom views for the header is a good pratice? I know this a big question but the answer will help me a lot.

Re: core data structure?
I've made the changes to my model, and the UI for this.

For example, I have products and kits (in reality), in the datamodel I have products, kit, and kitItems. kitItems have a qty attribute, and relationships to kits and products. For each kit, I want to calculate the total price of the included items (items can also be partial quantities). Previously I just used the bindings to @sum.price for the arrangedObjects I didn't really want to save the values as attributes, as I'd like the values to reflect changes to the product prices.

scrolling content view resizes visibly but bounds and frame don't change
This one is really bugging me. I have a WebView in a scrolling view and
content gets appended to it periodically (new tables appended; the entire
content of the WebView is reset each time via loadHTMLString on the
mainFrame).
VIsually, the webView correctly expands to include new content including
proper updating of the scrollbars; it looks fine and you can scroll up and
down the document as it grows.
The problem is that in code the bounds and frames of all views involved
never change to reflect the larger content of the webView. This means that
I can't make the view scroll to the bottom programmatically when new content
is appended which is what I want.
To make extra sure, I hooked up a lot of logging as follows; the output
never changes even when the content is clearly scrolling offscreen.
std::stringstream ssDbg;
NSRect docFrame = [[scrollView documentView] frame];
NSRect docBounds = [[scrollView documentView] bounds];
NSRect webFrame = [webView frame];
NSRect webBounds = [webView bounds];
NSRect contentFrame = [[scrollView contentView] frame];
NSRect contentBounds = [[scrollView contentView] bounds];
NSSize contentSize = [scrollView contentSize];
ssDbg << "\ndocFrame: (" << docFrame.origin.x << "," <<
docFrame.origin.y << ") " << docFrame.size.width << " x " <<
docFrame.size.height << std::endl;
ssDbg << "docBounds: (" << docBounds.origin.x << "," <<
docBounds.origin.y << ") " << docBounds.size.width << " x " <<
docBounds.size.height << std::endl;
ssDbg << "webFrame: (" << webFrame.origin.x << "," << webFrame.origin.y
<< ") " << webFrame.size.width << " x " << webFrame.size.height <<
std::endl;
ssDbg << "webBounds: (" << webBounds.origin.x << "," <<
webBounds.origin.y << ") " << webBounds.size.width << " x " <<
webBounds.size.height << std::endl;
ssDbg << "contentFrame: (" << contentFrame.origin.x << "," <<
contentFrame.origin.y << ") " << contentFrame.size.width << " x " <<
contentFrame.size.height << std::endl;
ssDbg << "contentBounds: (" << contentBounds.origin.x << "," <<
contentBounds.origin.y << ") " << contentBounds.size.width << " x " <<
contentBounds.size.height << std::endl;
ssDbg << "contentSize: " << contentSize.width << " x " <<
contentSize.height << std::endl;
my_log_debug(ssDbg.str().c_str());
The output forever even when the webView content has resized and become
scrollable:
[DEBUG 2010-09-08T23:57:02PDT]
docFrame: (0,0) 297 x 378
docBounds: (0,0) 297 x 378
webFrame: (0,0) 297 x 378
webBounds: (0,0) 297 x 378
contentFrame: (1,1) 298 x 379
contentBounds: (0,0) 298 x 379
contentSize: 298 x 379
I do find that the webView has one subView in its subviews array, and its
dimensions also never change, its bounds always are the same as its frame.
Anyone know what gives? Shouldn't the countentBounds and/or webBounds get
larger (taller) as new scrollbar-updating content is appended in the
webView? Then the following sample code to scroll to the bottom should
work:
if ([[scrollview documentView] isFlipped]) {
newScrollOrigin=NSMakePoint(0.0,NSMaxY([[scrollview documentView]
frame])
-NSHeight([[scrollview contentView]
bounds]));
} else {
newScrollOrigin=NSMakePoint(0.0,0.0);
}
...but it doesn't work because the contentView bounds never change even
though I can plainly see the webView now has a larger vertical dimension and
is vertically scrollable.
TIA,
Chris
