I'm just getting into iPhone development after many years doing Java development. I'm looking for the Objective-C equivalent to Java's BlockingQueue. Is there something like that? In case I'm going about things the wrong way, here's what I'm trying to achieve: I want to display, one at a time, chunks of data pulled from a network serve...
Given that I've taken care of releasing all the allocated variables. I also went thru the HIG to make the app as much as possible like what they want it to be. Do they check the my complexity of the code in the approval process? thanks ...
I've recently added landscape autorotation to my iPhone navigation based application, however I'm having a bizarre issue which I have no idea how to fix or whether my code is even the cuplrit. Its bizarre because I'm implementing everything as per the autorotation docs on Apple's developer center (that is responding to shouldAutorotateTo...
The iPhone is admittedly not the best platform for viewing code, but I'd like to optimize the mobile portion of my web site for the device as best I can. I'm having trouble getting code (Java code, in this case) to display properly. I'm using <pre> tags, along with some CSS to render a nice little background for the code. This looks...
I'm switching views in the context of a navigation view heirarchy, and I want to be able to determine at switch time what the prior view was that is being pushed under the new view. I'm trying this in a UINavigationControllerDelegate: (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIVi...
Hello, I'm analyzing the iPhone platform (for a paper). I've made a list with issues, developers/architects have to consider, before working with the iPhone SDK.

I put this code into all of my viewControllers: UIInterfaceOrientation orientation = [[UIApplication sharedApplication] statusBarOrientation]; if (orientation == UIInterfaceOrientationLandscapeRight) { CGAffineTransform transform = self.view.transform; // Use the status bar frame to determine the center point of the window's con...
I come from a C/C++ background and more recently flash. Anyway I wrote a 2D engine in AS3 and would like to get it running on the iPhone. To start with I converted it to C++. As a test I wrote a very simple C++ engine and added the files to a standard view-based application in XCode. I then added a UIImageView that covered the whole iPho...
Hi Folks, Our lovely app that downloads mp3s from our server into a local file on the phone then plays from that file was rejected for using too much bandwidth. I understand the rejection (we are downloading rather than streaming) and don't quibble with their decision... our first priority was quality of user experience. I am just w...
After running with the memory analyzer, my app seems to increase its memory consumption very slowly. The analyzer did detect memory leaks whenever certain events occur, which i quickly fixed. But this slow consumption of memory is occuring when im not doing anything in the app. The app basically just starts. Consumption is more noticeab...

More specifically - I go to the view with the UITextView, scroll maybe halfway(or to some other point) through the text, leave that view and when I come back the UITextView is showing where I left off. I have everything figured out except h...

Hi to all, I'm trying to disable scrolling in a UITableView when editing a UITextField embedded in a UITableViewCell. This is just to prevent the cell from being scrolled out of sight when edited (and also to avoid some related cell "Recycling" problems). While googling around I've seen that somebody suggested the obvious: tableView.s...
I've created a custom UITableViewCell in Interface Builder. (see the design view below) Notice that the image and labels are all reasonable positioned and there is almost no top & left padding. But when displayed in a UITableView it looks like the image below. What do I need to do to get rid of the unwanted padding? I believe that al...
