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...

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...

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...
I have a table which has roughly 10 cells, 4 different types. I subclassed UITextViewCell because I wanted to have an IBOutlet to a label and to a UITextField. Not sure if that was the best way of handling it, but it works thus far. Next, I had a cell for gender, so I figured instead of subclassing UITableViewCell, I took my already subc...
I'd like to implement a UITableView which displays say 20 rows at a time. But given the fact that I might actually have say 120 items to present, I'd like to handle this using some sort of paging: Populate table with first 20 items. When the user does a right-to-left swipe, reload the UITableView with the next 20 items. A left-to-right ...

I'd like one of my table rows to be a button that takes up an entire row of my UITableView. I figured the best way to go about this is to instantiate a UIButton, and give it the same frame size as an instance of UITableViewCell, and add that as a subview to the cell. I'm almost there, but quite a few pixels off to not get that perfect to...
