I need audio playback with these features: good performance (for game), pitch control, and ability to layer the same sample multiple times at the same time (polyphony). What would be a quick way to get this on the iphone sdk? Here's what I found out so far: There's no available libraries or sample code that does this, please show me ...
This perhaps isn't really a programming question, but it's something I'm sure lots of programmers other than me have faced! I've almost finished an iphone application I've been working on, the only thing I'm missing is a spot of art - a title screen, small and large icons, that kind of thing. I have no artistic talent, but I've been fin...
Hi, Anyone knows if Safari on the iPhone and iPod touch supports iFrame in design mode and if so, how I can enable it? I have tried following ways, but none work (but it works on my PC): theIframe.contentWindow.document.body.contentEditable = true; theIframe.contentWindow.document.designMode = 'on'; theIframe.contentDocument.designMo...
I am looking for a way to slide a UIPickerView (and UIDatePickerView) up over a view (UITableView in particular) when a particular button press takes place. I understand how to get the events for clicks into the UITableView, but there doesn't seem to be a good way to have the UIPickerView slide up on top of it... All the examples I hav...
I am working on adding in a settings bundle for my application as a cheap way of getting a GUI on my preferences. Is it possible to launch this from a button in my application or will my users always have to access it manually via the built in settings application? ...
Please pardon my lack of Photoshop skills, but I'm curious what type of strategy Apps like Facebook and AP Mobile News are using for the 'label slider' in their applications. Here's a quick snippet outlining what I'm talking about as I'm sure the name I'm labeling the utility as is being butchered: http://dl-client.getdropbox.com/u/57676...
I am looking to persistently display a game score in an iPhone app using cocos2d. Going off the code that cocos2d shows the FPS the app is running at: -(void) showFPS { frames++; accumDt += dt; if ( accumDt > 0.1) { frameRate = frames/accumDt; frames = 0; accumDt = 0; } NSString *str = [NSString st...
I'm looking to establish some kind of socket/COMET type functionality from my server(s) to my iPhone application. Essentially, anytime a user manages to set an arbitrary object 'dirty' on the server, by say, updating their Address.. the feedback should be pushed from the server to any clients keeping a live poll to the server. The buzzwo...
I have a couple of lines of trivial code such as the following: NSData *dataReply; NSString *stringReply; dataReply = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; stringReply = [[NSString alloc] initWithData:dataReply encoding:NSUTF8StringEncoding]; The problem here is, initWithData:encodi...
I'm looking to be able to reference certain state/objects through anywhere in my application. For instance, a user logs in to their application, I need to call a web service and retrieve the users information. Then I want to be able to access this information from anywhere in the application with something like the following: myAppDeleg...
In the iPhone SDK I don't see the same SCDynamicStore used on Mac OS X to get the SSID name that your wireless network is currently connected to isn't available. Is there a way to get the SSID name that the iPhone is currently connected to? I see some apps do it (Easy Wi-Fi for AT&T for one) but I can't find hide nor hair of how it's do...
I'm following iPhone dev courses from Stanford Open-University, and I've been blocked for 2 days on assignment3, maybe someone can help me here? The tasks are: Create a custom UIView subclass that will display your PolygonShape object Give your view class access to the PolygonShape object so that it can retrieve the details of the po...
So it's trivial to create a Settings style table on the iPhone. The problem is, they add a great deal of code as your Settings have a gamut of options/styled cells. One section might have a check list, another might have cells with accessory disclosures to drill down further, another might be labels with UITextFields. My question here i...
When the view property of a UIViewController is accessed, it first checks to see if it's got an existing view, and returns that. If not, it loads its nib or calls -loadView. When a controller receives a -didReceiveMemoryWarning message, the default behavior is to remove that cached view (assuming it's not in use at the time). If I ov...

Straight forward question. I'm trying to understand UI design more and how to make it work with code. In particular there used to be an app that went through several design sessions, named Where To? by Tap Tap Tap. They had a table which they turned into a radio dial, screenshot: My question is, is this nothing more than 22 or so imag...
Hi, I'm having trouble resizing a tableHeaderView. It simple doesn't work. 1) Create a UITableView and UIView (100 x 320 px); 2) Set the UIView as tableHeaderView of the UITableView; 3) Build and Go. Everything is ok. Now, I want to resizing the tableHeaderView, so I add this code in viewDidLoad: self.tableView.autoresizesSubviews ...
I have a complex settings style table where individual cells represent different aspects of a data model class. Users can click into a cell and edit individual attributes, such as say if I have a user class, a name, date of birth, etc. My question is, do I need to have an instance of UITextField for each unique cell? Can I just create on...
I am building application that required some data from iPhone's Call log(read only). The call log is a sqlite db located at "*/User/Library/CallHistory/call_history.db*". I used a jailbroken device to extract the log. However trying to open this location using the *sqlite_open3()* command I get a *SQLITE_ERROR* error, which according to ...
My application allows the user to enter a numeric value (currency) in a UITextField control, but the keyboard layout that I wish was available is unfortunately not one of the built-in options, so I had to choose the "Numbers & Punctuation" option in Interface Builder. Here's the corresponding dialog window in IB: So when my applicatio...
