Syntax around setTintColor?

Challenge requires setting a button's tint to red. Pretty sure I have the right method name with setTintColor, but I cannot seem to get the syntax correct. See my line after 'Enter your code below'. Colon or equals sign? UIColor object? Or the pointer *redcolor created by author? Do I even need UIControlStateNormal in that line?

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!

    [self.timerButton setTintColor: *redcolor forState:(UIControlStateNormal)];


}


@end

Hi erickwatson !

You might want to use

[self.timerButton setTintColor: redColor];

You don't need forState:(UIControlStateNormal) and you don't have to dereference the UIColor object redColor with an asterisk. Also you misspelled redColor by mistake.

Ugh. I could SWEAR I used that variant. Thank you!
