Array display help

What language?

 

Get a C book. Lookup what a "comma-expression" is. Then ask yourself why you are passing a comma expression to setStringValue. Then fill in the missing bits in this:

Code:

	NSString* theFormattedString = <what goes here>;
	[testLabel setStringValue: <and what goes here>];

And after that, how do you write this in one line (if that is what you prefer)?

 

Some other things to consider... what is the type of myList? What does the expression myList(0) return? Is myList a C function? If not, the syntax is not correct. Is it an NS(Mutable)Array? If so, you need to pass a message, not use a C construct like x() or x[].

Some references:
C operators

This table includes [], (), and ,. See which, if any, of these you need in this case. () is also used when invoking a function.

NSString

This should help you fill in one of the blanks in gnasher729's example, and would also help in achieving this in a single line.

NSControl's setStringValue:

This should help you figure out what sort of argument should be passed to this method.
