I'm working in an openGL for iPhone , and although everything works great I have to wait about a second in certain sections of the game which use a ton of sprite sheets. It's there any way to create a loading screen for such sections ?, or any way to know if a certain texture has finished loading with openGL? EDIT: I load my textures w...
I'm having some problems with the accelerometer. When I first started develop my game the controls felt very snappy and precise, but when adding more graphical elements the accelerometer feels like it's reacting very late and sometimes not as precise as before. I'm having a framerate of around 40fps. This is where I read the values (as ...
I'm typically using [self.tableView setContentOffset:CGPointMake(0,40)]; in order to hide the UISearchBar (that I set as header of the tableView) below the navigationBar. Everything works well in viewDidLoad: the searchBar is below the navigationBar when the view is loaded. Then I put the same line of code [self.tableView setContentOffs...

Since NSManagedObject is not thread-safe, I'm sending in the NSManagedObjectID from ThreadA (main thread) to ThreadB via an NSOperation derived class. The ...

Hi all, Based on Apple's TableViewSuite sample project (http://developer.apple.com/iphone/library/samplecode/TableViewSuite/index.html) I've taken the structure of number 5 there, to create custom drawn table cells. This is working great, and scrolling speed is fantastic now compared to when I was using nibs. It has however introduced ...
I’m scoping a new software project and haven’t had much experience with software development. This is a multipart question. What are some recommended books for web application architecture? We are basically looking to develop several front end applications (mobile and websites) that can query a central application pool that’ll hit our...

Hello, I set some values to NSUserDefaults and if I retrieve them without exiting the app, everything works fine. When I restart the app, the changes disappear in 95% of the time. In 5% of the time everything is being saved ok. I'm facing this problem for the first time. In my other apps I don't usually save NSString in NSUserDefaults....
I have several UIButtons in my app with different graphics for their On/Off states. The smaller buttons all display correctly without any flickering, but the larger button (320x90px) will flicker a black color over the button when pressed up to 75% of the time. This is on the iPhone, not the Simulator. I've set different combinations of ...

I don't want to do a scroll view, where the user just presses on the options. Instead I want the user to type the song name and if the song is f...
I have an IMAP server which creates mailboxes (folders) dynamically, and I'm having trouble getting the iPhone's IMAP client to refresh them. It normally sends a LIST command when it first logs in, but then it won't send another until you exit the Mail app a couple times and/or go back and forth to the account listing screen a couple tim...
I've managed to get my myself confused... I've got a fairly complex View Controller much of which is developed programatically. I'd like to pop up a "dialog" on top of the view controller at some point and I'd like to "design" that view in Interface Builder because it's fairly straightforward (background UIImageView, some UILabels and a ...

Does anyone know if it's possible to customise this to make it a different colour (the defa...
Hi! I want to use the in-app purchase in my app. Right now, I've created the half portion of my app. As far as I know there are two ways to deliver the app to the buyer using the in-app purchase. The first one is by creating your app fully functional, then if your app wasn't yet purchased, some features of this app should be locked and ...
A little background: I'm a C# developer starting to mess with the iPhone (have an idea for a simple 2D game). The only MVC programming I've done was for the web (ASP.NET MVC) so although I do have an understanding in MVC, I can't wrap my mind around one thing. Here's an example to illustrate. Say I have a simple app where all I want to...
