BlogReader Xcode Problem

Hi I've just started this program and I am having a issue right off the bat

This is the code

<code> [super viewDidLoad];

self.titlesArray = [NSArray arrayWithObject:

                    @"Getting started with WordPress",

             (!)    @"Whitespace in Web Design: What It Is and Why you Should Use It",

                    @"Adaptive Images and Responsive SVGs - Treehouse Show Episode 15",

                    @"Productivity is About Constraints and Concentration",

                    @"A Guide to Becoming the Smartest Developer on the Planet",

                    @"Teacher Spotlight: Zac Gordon",

                    @"Do You Love What You Do",

                    @"Applying Normalize.css Reset - Quick Tip",

                    @"How I Wrote a Book in 3 Days",

                    @"Responsive Techniques, JavaScript MVC Frameworks, Firefox 16 Treehouse Show Episode 14", nil];

</Code>

where I inserted the (!) I am getting (Too many arguments to method call, expected 1, have 11)

Can someone help me with this

Thanks Mike

Hey Michael,

From the name of the method you call, it's pretty obvious you should only provide ONE argument, like this:

[NSMutableArray arrayWithObject:@"Getting started with WordPress"];

If you want to initialize the array with more than one object, write code like this:

[NSMutableArray arrayWithObjects:@"string_1", @"string_2", @"last_string", nil];

DO NOT FORGET to ADD the "nil" at the end :).

Hope it helped you

Hi @Pavel

I changed it to the way you where saying so now it looks like this

<Code> self.titlesArray = [NSArray arrayWithObject:@"Getting started with WordPress", @"Whitespace in Web Design: What It Is and Why you Should Use It", @"Adaptive Images and Responsive SVGs - Treehouse Show Episode 15", @"Productivity is About Constraints and Concentration", @"A Guide to Becoming the Smartest Developer on the Planet", @"Teacher Spotlight: Zac Gordon", @"Do You Love What You Do", @"Applying Normalize.css Reset - Quick Tip", @"How I Wrote a Book in 3 Days", @"Responsive Techniques, JavaScript MVC Frameworks, Firefox 16 Treehouse Show Episode 14", nil]; </Code>

But same error.. I have no other (!) anywhere else just in that one spot.

Mike, you should be MORE CAREFUL, it is "arrayWithObjects", not "arrayWithObject".

And I'm telling you the SECOND TIME, everything is PRETTY OBVIOUS from the name of the method :).

Hope you'll get it working now

Glad to see you got it working Michael. Rookie mistake. Hahaha, but now I'm sure you'll never make that mistake again.
