Question

How can I get the parameter names to show up when making a method in objective-c?

For example, I notice that NSDictionary defines it’s method like this:

- (void)setValue:(id)valueforKey:(NSString *)key;

But it actually shows up in use as this:

[dictionary setValue:@"myValue" forKey:@"myKey"];

If I define the same stub above in my header file, it shows up as this in use:

[self setValue:@"My value" :@"My Key"]

You are missing a space:

- (void)setValue:(id)value forKey:(NSString *)key;
//                        ^ HERE

The signature that you provided uses identifier valueforKey as the name of the first formal parameter, and an empty segment for the key parameter.
