My app loads webpages off the internet using a UIWebView. However I'd like to modify the experience so the user won't perceive it to be a webpage. What are some of the things I can do? and how to do it? examples: - Show the page when everything is loaded? - Fade in effect? Suggestions please. ...
I would like to make a universal build that will run on the iPad and iPhone4. Basically this is the 'HD' build of a game which will run on the higher resolution display devices. As far as I know, the iPad and iPhone4 both run armv7, so choosing armv6 and armv7 doesn't seem to make sense. Although, this is what Apple tells you to do. ...

Hi, I have a project where a UITextView (for multilines) can be dragged around the screen. So far my solution to this has been an overlay of an invisible UIButton which when dragged its center is the same as the UITextView's center. However I've seen apps that seem to just allow the UITextView to be dragged and edited on the fly so it...
Hey there, I've got an app called AppAdvice that seems to be using Three20. I've noticed they have a mechanism in place within most of the tableviews that will automatically load more results when you scroll down to the bottom of the list and reveal the last row. The also have an indicator in the last row that tells the user more it...
Hi I've written a UIView subclass which adds a nice soft shadow underneath a png image. I'm overriding the drawRect method to draw the image and add the shadow. Now, when I try to do a scale/rotate-affine transform on the UIView (by calling the .transform method), I'm not getting the result I'm looking for due to the initial "flattenin...
I have a UITextView for text editing. By default, it has a small margin around the text. I want to increase that margin by a few pixels. The contentInset property gives me margins, but it does not change the text "wrap width". The text is wrapped at the same width, and the extra "margin" just causes the view to scroll horizontally. ...

During a refactor of an iOS project, I ran into this bear of a bug. During the linking phase, I get this message: ld: duplicate symbol _OBJC_IVAR_$_TinCanViewController.currentViewController in /path/to/TinCanViewController-E98A666B7AF2673A.o and /path/to/TinCanViewController-E98A666B7AF2673A.o As far as I can tell, it looks like i...

I'm setting up two buttons inside UITableViewCells. The cell itself shouldn't ever respond to selection, just my two buttons. Here's the code in question: -(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { static NSString *ident = @"ResourceResultsCells"; ResourceResultsTab...
I want to do this when the app loads, so I can either ask the user to log in (if not authenticated) or else continue. The only way I can think of is to call a random request (a GET that requires authentication) and check whether or not I get a valid response, but this seems inelegant. I am using the Foursquare API. Are there better w...

Hallo, I am working on a Core Data app and have to do some filtering based on dates. I've run some testing and it appears that when comparing NSDates, Core Data is comparing the time component of the dates as well. My code: - (BOOL)hasSpeakersWithinDateRangeFrom:(NSDate *)startOfRange through:(NSDate *)endOfRange { NSPredicate* d...
There's something I'm not seeing with Apple's push notification programming guide & related documentation. Is there a decent sample project (or well written tutorial) to show me how to do push location notifications? Here's what I want to do: Launch my app. Press the "remember this spot" button. Quit my app. [... time passes ...] Ge...

I'm developing an iPhone application that will access XML files (or something similar) from a server. I want to convert that data into a slick, native UI on the iPhone.
