• How to get Facebook share behavior with Facebook Connect on iPhone

  - by Benoit

  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.). Is there a way to emulate the "share" behavior with Facebook Connect, i.e. let Facebook pull the missing elements from the page being shared itself?

• iPhone file corruption

  - by sfider

  Is it possible (on iPhone/iPod Touch) for a file written like this: if (FILE* file = fopen(filename, "wb")) { fwrite(buf, buf_size, 1, file); fclose(file); } to get corrupted, e.g. when app is forced to terminate? From what I know fwrite should be an atomic operation, so when I write whole file with one instruction no corruption should occure. I could not find any information on the net that would say otherwise.

• Splitting jQuery into multiple files (for iPhone caching)

  - by Marko Ivanovski

  Hi, I was wondering if there is a way to split jQuery into multiple files, i.e. jQuery-1.4.2_part1.js jQuery-1.4.2_part2.js jQuery-1.4.2_part3.js ...and so on. The reason I want to do this is because the iPhone doesn't cache assets larger than 25kb and I really need jQuery to only be downloaded once. If you think there are other workarounds for this I am considering all options right now. Thanks, Marko

• Attach a formatter to a UITextField on iPhone

  - by charlax

  I'm trying to format an UITextField as user types text, for instance to show separator for thousands. I found this web page : http://www.iphonedevsdk.com/forum/iphone-sdk-development/16512-trying-add-commas.html It seems that shouldChangeCharactersInRange: is not a good solution. I thought of a custom UIView where the view would be updated as the user types digits, yet it would require recreating the wheel...

• Storing secret keys on iPhone source and project resources

  - by hgpc

  Is storing secret keys (internal use passwords and such) on iPhone source code and project resources (such as plist files) secure? Obviously nothing is 100% secure, but can this information be extracted easily from an installed app? How do you recommend storing these keys to use them in the source code? Just in case, this question is not about storing user passwords.

• How can I compile an iPhone App with Flash CS5 without a Developer License

  - by manderson12

  I understand Flash CS5 isn't the best way to make an app, but I'd really like to test out the apps I've made with it on my iPhone. Has anyone come up with a way to modify Flash CS5 so it doesn't require a Developer Certificate or Provisioning Profile (like the way you would modify Xcode so you can compile apps without paying $99 for the developer program)? I'd really appreciate it if anyone could provide some help. Thanks in advance.
