Question

Let’s begin with an example :

@interface myClass : NSObject {
    NSString * title;
}

-(id)initWithTitle:(NSString*)title;

Compiler doesn’t like this because title init parameter hides myClass title ivar.

But i don’t like these options :

-(id)initWithTitle:(NSString*)t;
-(id)initWithTitle:(NSString*)myTitle;
-(id)initWithTitle:(NSString*)_title;

So that’s a poll: what’s your convention?

Answer 1

Some people prefer calling their ivars _title or title_ and then they can just use title as parameter name in functions. Or you just call it aTitle or newTitle. There is no right or wrong way to do it.
