Working with Multiple View Controllers: Challenge 2 of 2

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 object to the tint property of the timerButton.

I've tried multiple variations of wrong code to implement the tint property with the redColor. I've searched the webs and the forum and rewatched the video.

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

@interface ViewController : UIViewController

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

#import "ViewController.h"

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    timerButton.setTintColor:UIColor *redColor = [UIColor redColor];

    // Enter your code below!
    [self.timerButton setTitle:@"Start!"

Hi Stephen,

I guess you're fed up with trying to get that to work by now!

Try something like [self.timerButton setTintColor: redColor];

That should work for you.

Thanks Steve, yes I have an upper limit on these things. It is about an hour, however today I was sitting in the sun so it was more like 45 mins.
