I am just starting out trying to design iOS apps on XCode 4.2
I have used C before, but only at a basic(ish) level; basically I can look at some code and tell you what is going on with about 90% of it - but when it comes to writing it I am terrible.
But I haven't used Objective-C before, so even writing my "Hello World!" program is proving to be a little difficult.
Can anybody help me with what the following does within the code:
- (IBaction)
- (id)
- sender
- @ (<< used before "Hello World!")
Thanks,
Chris
