Were do I go from here?

I'm not exactly sure what to do here:

Before we finish let’s also programmatically change the tint color of our button to something more appealing. I’ve set up a UIColor object for you to use and like last time, I want you to use the documentation or the Internet to figure out which method to use. Assign the redColor UIColor object to the tint property of the timerButton.

ViewController.h 
#import "UIViewController.h"
#import "UIButton.h"

@interface ViewController : UIViewController

@property (strong, nonatomic) IBOutlet UIButton *timerButton;

@end
ViewController.m 
#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    [self.timerButton setTitle:@"Start!" forState:UIControlStateNormal];

    UIColor *redColor = [UIColor redColor];

    // Enter your code below!


}


@end

Here is the documentation page he mentions using. You want to find the the thing that will help you set the tint color of the button. Remember that properties can be set using dot notation.

If you follow the link I posted above it will take you right to the Apple provided documentation that will show you how to do this.

I don't want the link. I saw that on my own. This challenge is so F***d up i just want to move on already. Do you have the answer? Yes, this is a cop out, but at this point, I really don't care anymore. Thanks, if you can help me

the question is wrong, because instead of changing the background color with setBackground you have to do the following it worked for me after different lines of code i input

self.timerButton.tintColor = redColor;

Ugh, these quizzes are really frustrating - while I understand their purpose.. the way they're worded is... less than ideal.

I agree. Don't worry, the Objective-C challenges are the hard ones. All the other CCs are easy.
