• Cocoa & Cocoa Touch. How do I create an NSData object from a plain ole pointer?

  - by dugla

  I have malloc'd a whole mess of data in an NSOperation instance. I have a pointer: data = malloc(humungous_amounts_of_god_knows_what); uint8_t* data; How do I package this up as an NSData instance and return it to the main thread? I am assuming that after conversion to an NSData instance I can simply call: free(data); Yes? Also, back on the main thread how do I retrieve the pointer? Thanks, Doug

• Passing in **kwargs from Flex over PyAMF

  - by cookiecaper

  Anyone know if it is easily possible to send **kwargs over PyAMF from NetConnection.call()? I would like it. I could write a wrapper around the actual function and expose that and perform some parsing manually to determine the kwargs to pass in, but I don't want to do that. I will just use a normal argument list in that case.

This post shows that you can bring the dialogue to the front if you convert the process to a foreground process. If you keep the process a background process, however, is there any way to achieve this behavior?

• Using Ruby/Python code in an iPhone OS app?

  - by igul222

  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?

• Does calling a click method effect the HtmlPage object if there is a 404?

  - by Blankman

  If I call a click method on a HtmlAnchor, and say that page returns a 404, does that mean the HtmlPage will effect, so searching for another link on the page will result in an error because the page's HTML is the error page (assuming the link is NOT on the error page). Can I manually set the page's HTML, and then locate and click on links and continue on from this approach? (other than connecting via a URL)
