• use AMF + Flash remoting instead of JSON + REST on iPhone?

  - by Henry

  Although iPhone support JSON natively, and easy to consume RESTful services, AMF is a binary protocol and it supposes to use much less bandwidth. Do you think using AMF + Flash remoting is a good idea? Just found this AMF library in cocoa (Objective-C): http://github.com/nesium/cocoa-amf/

• Creating a Virtual Webcam Device for OS X

  - by andsve

  I am looking for a solution to create a "virtual" webcam device under OS X (that acts just as a normal hardware webcam, but the application has full control over what to output). I'm fairly experienced with C++, but not so much with Objective-C and OSX/Cocoa programming. Anyone that can point me in the right direction, where to look and what I should be looking for? I've searched, but most of the results seems to focus on Windows and DirectX. Thanks!

• Why Emacs/Vim/Textmate? Isn't Xcode good enough?

  - by ivanTheTerrible

  Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?

• How to turn off startup text of GNU gdb in XCode

  - by willc2

  I'm new to XCode 3.1.2 and Objective-C 2.0. I've just discovered using breakpoints for logging instead of littering the code with millions of NSLog() statements. The problem is, when the debugger starts up it spews half a screen full of status and credits info into the console. Is there any way to suppress this text?

  All examples I find on shuffling arrays are for NSMutableArrays. Copying an NSArray to an NSMutable array, shuffling, then copying back always crashes the application. Is it even possible to shuffle an NSArray? Anything in objective-c similar to Collections.shuffle() (Java)?

• How to store enum values in a NSMutableArray

  - by Oysio

  My problem is since an enum in objective-c essentially is an int value, I am not able to store it in a NSMutableArray. Apparently NSMutableArray won't take any c-date types like an int. Is there any common way to achieve this ? typedef enum { green, blue, red } MyColors; NSMutableArray *list = [[NSMutableArray alloc] initWithObjects: green, blue, red, nil]; //Get enum value back out MyColors greenColor = [list objectAtIndex:0];

• Is it true that one should not use NSLog() on production code?

  - by jpm

  I was told this a few times in this very site, but I wanted to make sure this is really the case. I was expecting to be able to sprinkle NSLog function calls throughout my code, and that Xcode/gcc would automatically strip those calls out when building my Release/Distribution builds. Should I avoid using this? If so, what alternatives are most common between experienced Objective-C programmers?
