I have a scrollview that automatically generates a series of subviews containing imageviews. The concept is that it's pretty much a custom PDF style reader, where each page is loaded in to an imageview as an image. There are three "layers" - the outer UIScrollView, the automatically generated subViews and the imageview inside the subview...
Hi, I'm seeing these all over the place but I'm wondering what controls are used here? What is the thing with the arrow pointing right? Is it a UIRoundRectButton with a ">" (greater than) character? What is the box with the rounded corners below which allows separaring content using a horzontal line? Also looks like a button... Th...

Hello all, I wanted to clarify something: I.e when I add a UIVIEW To i.e another UIVIEW programatically. i.e [theview addsubview:thechildview]; I need to release thechildview because theview increments the retain count.

In iOS's Mail app, when you enter in the email of someone who is in your contact list it formats the text in an interactive bubble. I can't seem to find any obvious way to do this, and it's exactly what my app needs to do, and I'm not even sure where to start. Any pointers to where to look would be appreciated! ...

So far, I have this approach, which works fine for local files: @interface RJRStreamReader : NSObject { @private NSFileHandle *fileHandle; NSStringEncoding encoding; NSString *...

I have an object that serves as a UITableViewDataSource and a UITextFieldDelegate. In cellForRowAtIndexPath, I create a TextField inside each TableViewCell and assign self as the TextField's delegate. When I click a bu...

I have a UITableView that changes its data very often. (It's just NSStrings, stored in an NSArray.) Method 1> [self loadMyArray]; Method 2> [myTable reloadData]; Where would I put those 2 methods... so they get called EVERY time the view is displayed?

How can i simulate an empty tableview and navigation bar as per the guidelines. "Simulate Interface" in IB fills the view with the standard California data. I tried creating a basic navig...
This is my first post on SO, so hi! I'm new to Xcode and Obj-C too so don't be too harsh. I am following the demo from Standford University youtube.com/watch?v=L-FK1TrpUng For some reason i've hit an error.

Hi all, I'm trying to figure out the best way to automatically add NSLocalizedString() around a string in xcode. Ideally I'd like a way that I could position the cursor within @"foo", press a key binding, and it'd be turned into NSLocalizedString(@"foo", nil). I've had a look at the documentation for user scripts and can't see an obvi...
Hi, I am currently writing an application which simulates key press events in Mac OSX to control ioquake3. My current approach is to create the key press events with the Quartz Event Services. This works fine with e.g. TextEdit but not with ioquake3. CGKeyCode keyCode = 126; // 126 is the "up" key CGEventRef event1 = CGEventCreateKeybo...
