I want to merge 5 "sublayers" to one single texture (you know, somethin' like Flatten Image in Photoshop) in OpenGL ES 1.x iPhone. I'm new to OpenGL, and just haven't find the answer yet.
Coming from the .NET world into ObjC and iPhone development, I'm used to providing design-time support for my UI classes. For example, say that I have a custom button class with a color property. I want to be able to set this color in design time from IB. How can I accomplish this? Is it even possible? Worth the effort?
Hi
For my iPhone application I need to read some content of a plain html file on the web. It's just some text within a pre-tag. However I don't want to download the whole file and then get the line I need.
The format is:
TextTextTextTextTextTextTextText
TextTextTextTextTextTextTextText
TextTextTextTextTextTextTextText
TextTextTextTextTextTextTextText
I only need the first line and then close the connection to that resource.
Thanks in advance.

I am developing an iPhone app that need to display some message on lock screen. I have tried to use local notification or CFUserNotification but neither of them can display the message on top of the lock screen. For CFUserNotification I have tried kCFUserNotificationAlertTopMostKey (refer this similar question) but it still not work. I am not going to hook springboard since my phone is not jailbreak. I have found an app do implement it and I have tested on my none-jailbreak iPhone iOS 6.0, don't know how to implement this.
Any help much appreciated.

At WWDC 09 in Session 304 "Game Development for iPhone, Part 1 (Graphics, Audio)", about 6 minutes after start of the Session, they showed off a small but nice OpenGL ES game demo and repeating over and over again how easy it is to implement. Is that source code of the demo available somewhere for download?
I found email composer sample code from iphone OS Ref Library. Here is a code-
Code:
NSArray *toRecipients = [NSArray arrayWithObject:@"[email protected]"];
NSArray *ccRecipients = [NSArray arrayWithObjects:@"[email protected]", @"[email protected]", nil];
NSArray *bccRecipients = [NSArray arrayWithObject:@"[email protected]"];
My question is how to take user's input? Here all email address are predefined in code. so what are the IDs of to, CC, Bcc, subject and body fields?
I've noticed a lot of examples for iPhone apps in the Application Delegate
- (void)applicationDidFinishLaunching:(UIApplication *)application
have
[window addSubview: someController.view]; (1)
as opposed to
self.window.rootViewController = self.someController; (2)
Is there any practical reason to use one over the other? Is one technically correct? Do controller's have the an equivalent command to number (2) like
self.someController.rootController = self.someOtherController; // pseudocode

I tried CoreData for iPhone app, but it's memory-hogging when entity instances are fetched. After they are released, memory usage doesn't decrease at all. Is there any way to treat them in a low memory usage.

I have a series of buttons that have suit symbols on them. Currently I provide these suit symbols as bitmaps. In preparation for iPhone 4 I'd like to use text instead. However Interface Builder rescales the button to account for whitespace underneath the symbol so I can't get the image to fill the button completely.
Any hints on getting Interface Builder to behave?

I'm trying to write an iPhone offline webapp using jqtouch/jquery. When I disable my connectivity, it looks like the jquery .load() function silently fails and doesn't even call its callback function. I've set $.ajaxSetup ({cache: true}); but it seems to have no effect. I also have my manifest file etc. working fine - the only issue is the .load() function.
Any ideas?

In iPhone I need to set the background view of a UITableview. From 3.2 SDK I can in code use something like:
[self.tableView setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"mycustombackground.png"]]];
But how can I do the same in interface builder? It would be great if I could just set the background view directly in interface builder. But can't seem to find this property, where is it?
Thanks!
