This is my current set up for my multiplayer game: A view that gives connection tips and warns the user that multiplayer will not work on the 1st Gen iPhone or ipod Touch. There is a "connect" button that pushes the game view and starts the GKPeerPicker. Unfortunately, I don't have a 1st Gen iPhone or iPod Touch to test what happens...

I'm currently doing this by creating a HTML version of the document and setting this as the body of the message.This works fine when viewing the email in MFMailComposeViewController, but on the receiving end (MobileMail.app, GMail Webinterface, OSX Mail.app) the...
I'm attempting to talk to a web service for locations within the zoomed-in or zoomed-out area on an embedded MKMapView. In the regionDidChangeAnimated method of my view controller (this is the method that I use to trap any user gesture on the map), I call the following: NSLog( @"latitude delta = %f", mapView.region.span.latitudeDelta );...
I'm following this tutorial, attempting to learn a bit about iPhone development, and there come a point where the author uses the stringWithContentsofURL method but xcode is telling me that there is no stringWithContentsofURL method found. I've done some searching and I've not been able to come up with a solution. This is a screen shot...

I have a UIViewController with 4 UITextFields, 3 of them use the NumberPad and 1 uses an ASCII keyboard. I can't get the ASCII keyboard to dismiss when the user touches a background button outside the text field. The background button works fine to dismiss the NumberPads but doesn't dismiss the ASCII keyboard. Yes, the ASCII keyboar...
Good morning all. I'm having a small crisis with table views in a 3.1 app. I have a table view with some complex tableViewCells being loaded from a nib, and they're not being reused. Feeling it might have something to do with loading them from a nib, I decided to try a simple test project to see if cells are being reused using nothing...
I used to have the following snippet of code in viewWillAppear method of a tableviewcontroller. What it essentially did was to start with the first row selected when the view was loaded. // Select the first row by default and set the datePicker NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self.tableView se...

I'm trying to put a text badge on my Iphone app with the undocumented setApplicationBadgeString method. The problem I'm having is getting the number of characters right. Sometimes I can fit characters, sometimes it replaces part of my string with dots. I've seen the same behaviour on UILabel too, if the text doesn't fit, it gets cut off...
Hi, I am working with CGLayers, and its blend mode constants, as kCGBlendModeDifference, kCGBlendModeHardLight, kCGBlendModeLuminosity, etc. I would like to build an array out of these constants and use them by index, in an instruction like CGContextSetBlendMode(context, [myArrayOfBlendModes objectAtIndex:x]); but I have two probl...

Hi. I'm programming an puzzle game for iPhone using openGL. There Is one very weird "bug" ( I'm not sure what It is)... whenever I touch the screen a great number of times in a short period of time my app closes, without giving a warning or error.

As simple as possible: I have a very simple Excel spreadsheet with just over 1k records. I want to use this as a static datasource for an iPhone application. What's the best plan of attack? Possibilities in my mind: 1) Reading the XLS directly as a data source: is there an Obj-C lib for this? 2) Converting the XLS to a format that Ob...
This crashes (but without outputting any info to the Debugger; no dump, no trace): adMobAd = [AdMobView requestAdWithDelegate:self]; // start a new ad request [adMobAd retain]; // this will be released when it loads (or fails to load) I thought it was because my code isn't executing in NSDefaultRunLoopMode, which AdMob says is require...
After I call [self.navigationController popToRootViewControllerAnimated:YES]; I can see in the root view controller that viewWillAppear enters and exits. Then I see a message on the console that reads *** -[CFString release]: message sent to deallocated instance 0x4a9eab0 And then my app abruptly terminates. I don't think it's in...
On an iPhone 3GS, the image captured by the camera has 2048x1536 pixels. If my math is correct, opening this image on a CGLayer will consume 12.5 MB. Springboard will terminate any application that reaches beyond 12 mb (at least this is what happens to me). Manipulating this image with a function like CGContextDrawLayer will consume an...
