Hi all, I have created a CALayer (I added several shapes to the layer, but ultimately, I have a single CALayer), and I am having a LOT of trouble adding it to a CGImage. I have found some references to [CALayer renderInContext:ctx], but I am not sure how to implement it. Has anyone done this before? Cheers, Brett ...

I would like to be able to share these articles on Facebook, using a password and email-address that was set somewhere programmatically (not using Facebook-Connect, mostly because I want the design to be the same, whether you log in to Twitter from the app or in...
I understand that CGAffineTransformMakeRotation can rotate an image, and CGAffineTransformMakeTranslation translates an image. I also understand CGAffineTransformConcat can merge two transformations. However, I cannot seem to figure out a way to move an image on an arc using both of these. I understand this is more a mathematical questio...

I have this while loop in xcode. The loop seems to work fine since I printed my i++ in console. But for some reason it only checks my IF statement the first time around. I can only add one title into the MutableArray called sectionZeroTitleArray. I have many arrays in this loop so it might get confusing. I will try my best to explain. ...
Hello again, I was able to make the targets spawn randomly along the top of the screen and dissappear at the bottom of the screen.

Here is the code: -(void)addTarget { ...

I don't wan...
I have a use case where a UIWebView may need to connect with a web server secured with NTLM. I also have a use case where I already have the credentials to be passed. So instead of forcing the user to enter them, how do I perform the handshake with the UIWebView? UPDATE: Using this method here works well enough when you are doing sim...
