Help with Task - Set the 'robotImages' to the animation images property of 'imageView'

But where do you put the imageView.animationImages line of code? I've read all the posts here a few times and it's not sinking in where to put this stuff. I'm really struggling with the terminology and nomenclature of Obj-C.

NSArray *robotImages = [[NSArray alloc] initWithObjects:[UIImage:@"Robot1"], [UIImage:@"Robot2"], [UIImage:@"Robot3"], [UIImage:@"Robot4"], nil]; What do I need to add to this code to get through the challenge? Specifically, 'where' do I add it?

You've got the two statements now all you have to do is assign robotImages to imageView.animationImages.

Where do I put that into the code? I tried to put it in the beginning but that didn't work.

/* Write your code below this line */ imageView.animationImages *robotImages = [[NSArray alloc] initWithObjects:[UIImage:@"Robot1"], [UIImage:@"Robot2"], [UIImage:@"Robot3"], [UIImage:@"Robot4"], nil];

In the first line you define the array:

NSArray *robotImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"Robot1"],
                                                        [UIImage imageNamed:@"Robot2"],
                                                        [UIImage imageNamed:@"Robot3"],
                                                        [UIImage imageNamed:@"Robot4"],nil];

Next line you assign the robotImages instance variable to animationImages

imageView.animationImages = robotImages;

Thanks. I picked up a Big Nerd Ranch objec C book to help out a bit.

Wow. Brain slowly turning to soup...

So in our project, we flipped it from what we see in the challenge. We created and synthesized the imageView array and then assigned the animationImages to imageView using all of the crystal ball pics.

In the challenge, we need to define an array and then assign it an instance variable?

I couldn't even begin to tell you if I think I'm making sense.

Mike Mitchell You got it. Spot on!

Still not solved, I am caught up on the same issue.

Set the animation images property of 'imageView' to 'robotImages'. Important: The code you write in each task should be added to the code written in the previous task. Recheck Work Bummer! Make sure you create an NSArray named 'robotImages' with instances of UIImage objects.

ViewController.m

1 UIImage *image = [UIImage imageNamed:@"robot.png"]; 2 UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; 3

4 /* Write your code below this line */ 5 imageView.robotImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"Robot1"], 6 [UIImage imageNamed:@"Robot2"], 7 [UIImage imageNamed:@"Robot3"], 8 [UIImage imageNamed:@"Robot4"], nil]; 9

10 self.imageView.animationImages = robotImages;

What am I doing wrong?????? There is no Tips along the way if you make errors, and I am stuck, cannot progress any further, this one Code Challenge is really putting me off as nothing seems to be accepted and the video isn't very insightful when the Code Challenge Question doesn't even specifically match the code I am looking at in xCode.

Sorry you have issues but that's the goal of the code challenge to help you think above and beyond what was taught in the video. Here are some issues with your code:

1. robotImages is not a property of imageView. It should be declared as an instance variable. Which means that you would be declaring something like NSArray *robotImages = ....

2. Once you create a robotImages instance variable then you can set that to the animationImages property of imageView.

3. You cannot not use self because there are no properties declared using @property. They are all instance variables.

Haha. Oh, thanks. Got it.

I mean create an instance variable named robotImages of the class NSArray.

Unfortunately, your statements are mixed up. When you are declaring an array the left and right side of your statements must equate to allocating and initializing a new array, which would be the left side of the first line and right side of your second line.

NSArray *robotImages = [[NSArray alloc] initWithObjects:[UIImage imageNamed:@"Robot1"],[UIImage imageNamed:@"Robot2"],[UIImage imageNamed:@"Robot3"],[UIImage imageNamed:@"Robot4"],nil];

Once you have created that array (as shown above) then it should be assigned to the animationImages property of imageView, which means that imageView.animationImages is on the left side and robotImages is on the right.

Thanks Amit. I understand now!
