I want to know how to write function & variables names,I mean,

-(void)is_open;?
-(void)Is_Open;?
-(void)IsOpen;?
-(void)isOpen;?

and variables

IBOutlet UIButton *cancelButton;?
IBOutlet UIButton *cancel_button;?

how do you write them?

Thank you!

Look at any Apple class. Method names always start with a lower case letter and then each subsequent word is has an initial upper case letter. Words are never separated by underscores. So there is only one viable answer:

-(BOOL) isOpen;

Also, make sure you've reviewed this: Coding Guidelines for Cocoa

C naming is case sensitive and allows underscores. Anything that you find readable will work. If you read a lot of Apple sample code and find that to be a readable coding style, you might want to copy those naming convention. If not, don't. The C code will still compile just fine.
