I can't get past task 1 of 3 in this code challenge. The question: "Let's add animation to the Random Quotes app. A property named 'imageView' has been already defined. Assuming you have images named '01.png','02.png','03.png', create an array of UIImage objects and assign them to the 'animationImages' property of 'imageView'." Thanks for the help. My code is:
self.imageView = [[randomQuotes alloc] init];
self.imageView.animationImages = [[NSArray alloc] initWithObjects:
[UIImage imageNamed:@"01.png"], [UIImage imageNamed:@"02.png"],
[UIImage imageNamed:@"03.png"], nil];

16,433 Pointswell, the questions states that you should Create an array of UIImage objects and assign them to the 'animationImages' property of 'ImageView'.
However, the first part of your code is completely unnecessary. it doesn't contribute to what the question is asking for. Oh yeah, and just trying to copy exactly what you saw in the video won't work. so your code should be:
self.imageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"01.png"], [UIImage imageNamed:@"02.png"], [UIImage imageNamed:@"03.png"], nil];

This is my code:
import "THViewController.h"
@implementation THViewController
-
(void)viewDidLoad { [super viewDidLoad];
// backgroundImage is a local variable UIImage *backgroundImage = [UIImage imageNamed:@"background"]; // imageView is a property self.imageView = [[UIImageView alloc] initWithImage:backgroundImage];
// Add your code below! // Remember 'imageView' is a property // so refer to it as 'self.imageView'
self.imageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed:@"01.png"], [UIImage imageNamed:@"02.png"], [UIImage imageNamed:@"03.png"], nil]; self.imageView.animationDuration = 5.0f;
}
- (void) imageView { [self.imageView startAnimation]; }

10,965 PointsHey Rashii,
sorry to jump in here, I have exactly the code that you have above as the answer but my problem is i dont know if i should be replacing the code there already or adding to it, and if i am adding to it, which line ?
seems like a crazy question i know but thats probably what i am struggling with the most on my coding journey so far (only 3 weeks), that is the order the code needs to sit. does this have to do with the order we want it to load and/or the life cycle ?
appreciate your help.

16,433 PointsI completely apologize for this late post, somehow i didn't get the notification.
but you should be adding the code above to the area underneath in the code challenge where it says add code below.
