This comes out of my search for a smart variant of NSLog(). One key feature of BetterLog() is that the NSLog() replacement compiles out to nothing for release and distribution builds. The proposed solution (see eg http://stackoverflow.com/questions/300673/is-it-true-that-one-should-not-use-nslog-on-production-code) is define a preprocess...
I'm not sure how to ask this question, but here goes... I am rendering a PDF page into a view and adding it to a UIViewController. Works fine, except for some PDF files.

Hi, I have been studying how to display a modal view with UIAlertView for a few hours and I understood that showing it does not "block" the code (the modal window is displayed and the program keeps running - we must use delegate to catch the selected actions on this modal window). Then I studied several examples and noticed that every e...

Now my question is two-fold: if I say have a link in there to go to either my website or something then people click that link and it's within the uiwebview! How would I go about launching safari instead? target='_blank' doesn't seem to ...

Then I added one png for the "default state configuration" and another png for the "highlighted state configuration". Let's just assume these png's are a red box and a blue box.
