So, I'm looking to implement the ability for a plugin I wrote to read a touch "swipe" from a touch-capable internet device, like an iPhone, iPad or android. Is there anything out there? I'm not looking for something as full as jQtouch, though was considering reverse engineering the code I would need out of it. Any suggestions on the be...

I read about NSLocaleCurrencySymbol, but where would I find the variable used to determine the "number of decimal places" used in a country's currency? I.E. In the USA, it's common to see dollar amounts written with 2 decimal places: $1.23 What about many other countries? Thanks. ...
Hello everyone, I have a program that will scan the contents of a website, and display it in a textbox. The problem is that it shows the html source. For example if my html code was: <html> <body> <p>Hello</p> </body> </html> instead of just showing hello, it'll show the code above... How can I get my objective c program to just ...
Right now I am using a bitmap array to get a specific pixel color value from a UIImage. I couldn't find anything online other than the code from here: http://www.markj.net/iphone-uiimage-pixel-color/) Which works well enough. I wanted to know if there are any other ways to get the color for an image. Looping through myself feels a littl...
With the standard share at http://www.facebook.com/sharer.php one only needs to specify a URL. Title and thumbnail are automatically pulled from the web page (perhaps with the help of meta tags). With Facebook Connect (I am using the iPhone SDK), I need to supply everything explicitly (URL, title, caption, description, images, etc.). ...
I'm making a line graph on the iphone using core graphics and instead of having a jagged chart, I want to smooth it out like in good old math class. What's the formula to pick where to put the control points for CGContextAddCurveToPoint? CGFloat cp2x = (x + x + prevX); CGFloat cp1y = (prevY + prevY + y); CGF...

I have a CALayer that I apply a perspective to using a CGTransform3D and specifying the m14 property. When the perspective is applied, the layer has jagged edges. I've heard people mention that adding a 1px transparent border around the layer will help with this. I don't know how to do that. I have tried using the border and borderWi...
Hey SO, This might be a long shot, but I'm having a bug that I'm fairly sure is specific to my program. I'm animating something, and between then the animation starts and stops, something is influencing my animated view, and changing it's size. I was wondering if there was a way in the debugger, or really in anything to see what's inf...

I was attempting to clean up the implementation for a sub-panel on a navigation controller stack, so that the navigation bar could be customized in the XIB instead of doing it manually in the viewDidLoad method. The original (working) setup had the XIB set up with the "File's Owner" class set to the view controller class, and then the v...
Want to draw an UIImageView which has an CGImage, and the UIImageView has alpha 0.5f. But this CGContextDrawImage function doesnt take an transparency value. So how could I draw an image slightly transparent? To be clear: The image itself is not transparent, but I want it to be "dimmed" a little bit. Just like you would do with an UIIma...
Apple says: Tip: For best performance, make sure that you set the smallest possible clipping area for the objects in the transparency layer prior to calling CGContextBeginTransparencyLayer. Sounds good, but how would I set that clipping area to the thing which I want to draw transparent? ...

My app needs to use a library which is only available for Python and Ruby. From my understanding, Apple allows Ruby to run on iPhone as long as users can't execute arbitrary code (Rhomobile uses Ruby). How can I bundle Ruby/Python with my app, call a function from my Obj-C code, and get the result (a string) back in C or Obj-C format? ...
