Code Challenge: Image Based Animation, Task 4/4

@paul your answer is at the 8:50 minute mark in this video

Hey Paul,

It looks like you've done all of the work to set up your animation, but remember that you need to actually tell your application that you want your animation to start. In addition to checking out the video tutorial for image based animations here on Treehouse, you might also check out this entry to the iOS Developer Library on Apple's iOS development site.

Good luck!

J.T.

You have to keep watching until he gets to the point where we talks about the - (void) startAnimating method. :-)

Thanks @Amit and @J.T.!

@Amit The 8:50 mark shows the following code:

imageView.animationRepeatCount = 1;

I already have this in it, so why is it still giving me the error?

@Amit Now my existing code isn't working (it says that I need to create robotImages, even though I already have, as you can see in the original post).

Any ideas?

@Amit Never mind about that last post (simple typo).

@J.T. Ah, ok. Thanks for your help! Hopefully it works this time.

Yep, it worked. Thank you very much!

Hello all,

I can't tell you how many times I've watched the video from 00:08:50 on, but I'm pulling out my hair trying to figure out why I can't call the right method that refers to imageView? I'm totally at a loss. Posted is my umpteenth try. I'm ready for help.

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

/* Write your code below this line */ [view insertSubview:imageView atIndex:0];

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

imageView.animationImages = robotImages;

imageView.animationDuration = 5.0; imageView.animationRepeatCount = 1;

-(void) robotImages { [imageView startAnimating]; }

it should be just [imageView startAnimating];

@Dogancan I could have sworn that I tried that from the get, good grief...yup. Coding...ARGH!

-Cheers!

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

[view insertSubview:imageView atIndex:0];

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

imageView.animationImages = robotImages; imageView.animationDuration = 5.0; imageView.animationRepeatCount = 1;

[imageView startAnimating];

what is wrong???

Brad Izquierdo Your code looks right except you should remove this line:

[view insertSubview:imageView atIndex:0];

I got it, thanks Amit Bijlani !!
