Is it possible to program iPhone in C

Question

I m all for language diversity  but Objective C is insane  So I m curious  is it possible to code iPhone apps with C   while using the Cocoa API  etc

Having some experience of this  you can indeed use C   code for your  core  code  but you have to use objective-C for anything iPhone specific   Don t try to force Objective-C to act like C    At first it will seem to you this is possible  but the resulting code really won t work well with Cocoa  and you will get very confused as to what is going on  Take the time to learn properly  without any C   around  how to build GUIs and iPhone applications  then link in your C   base

I use Objective-C to slap the UI together  But the hard guts of the code is still written in C     That is the main purpose of Objective-C the UI interface and handling the events  And it works great for that purpose   I still like C   as the backend for the code though  but that s mainly becuase I like C    you could quite easily use Objective-C for the backend of the application as well

Short answer  yes  sort of  You can use Objective-C    which you can read about at Apple Developer Connection   If you know C   already  learning Objective-C would be pretty simple  if you decided to give that a try  More info on that topic is at the ADC as well

Although Objective-C does indeed appear to be  insane  initially  I encourage you to stick with it   Once you have an  a-ha  moment  suddenly it all starts to make sense   For me it took about 2 weeks of focused Objective-C concentration to really understand the Cocoa frameworks  the language  and how it all fits together   But once I really  got  it  it was very very exciting   It sounds clich    but it s true   Stick it out   Of course  if you re bringing in C   libraries or existing C   code  you can use those modules with Objective-C Objective-C

First off  saying Objective-C is  insane  is humorous- I have the Bjarne Stroustrup C   book sitting by my side which clocks in at 1020 pages   Apple s PDF on Objective-C is 141   If you want to use UIKit it will be very  very difficult for you to do anything in C     Any serious iPhone app that conforms to Apple s UI will need it s UI portions to be written in Objective-C   Only if you re writing an OpenGL game can you stick almost entirely to C C

You have to use Objective C to interface with the Cocoa API  so there is no choice  Of course  you can use as much C   as you like behind the scenes  Objective C   makes this easy    It is an insane language indeed  but it s also    kind of fun to use once you re a bit used to it   -

Yes but Thinking that you can program every kind of program in a single language is a flawed idea unless you are writing very simple programs  Objective C is for Cocoa as C  is for  NET  Use the right tool for right job  Trying to make C   interact to Cocoa via writing bridging code and trying to make C   code behave according to Cocoa requirements is not a good idea neither expecting C   performance from Objective C is  You should try to layout design and architecture of app keeping in view existing skills and determine which part should be written in which language then build accordingly

I m not sure about C    but you can definitely code iPhone applications in C   using a product called MonoTouch   You can see this post for detailed discussion on MonoTouch Vs Obj-C  How to decide between MonoTouch and Objective-C

It may be a bit offtopic  but anyway  You can program c   right on iOS devices  Check out CppCode ios app - http   cppcode info  I believe it helps to learn c and c   and objective-c later

I m in the process of porting a computation-intensive Android app written in Java to iOS6  I m doing this by porting the non-UI parts from Java to C    writing the  minimal  UI parts in Obj-C  and wrapping the former in a   small  C interface using the standard C C   technique  so that it can be accessed from Obj-C  which is after all a superset of C   This has been effective so far  and I haven t encountered any gotchas  It seems to be a legitimate approach  since Xcode lets you create C   classes as well as Obj-C classes  and some of the official sample code does things this way  I haven t had to go outside any officially supported interfaces to do this   There wouldn t seem to be much to gain from writing my remaining UI code in C   even if it were possible  in view of the help given to you by the interface builder in Xcode  so my answer would be that you can use C   for almost all your app  or as much of it as you find appropriate convenient
