5,120 PointsCode Challenge: Image Based Animation
Hello,
I can't correctly write code in task 1 of 3:
"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'."
My code is:
#import "THViewController.h"
@implementation THViewController
- (void)viewDidLoad {
[super viewDidLoad];
self.imageView.animationImages = [[NSArray alloc] initWithObjects: [UIImage imageNamed: @"01.png"], [UIImage imageNamed: @"02.png"], [UIImage imageNamed: @"03.png"], nil];
// 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'
}
@end
Tell me please - whats wrong with this code? I write code from video in Xcode and its work, code above is almost the same...

Courses Plus Student 2,743 PointsHello,
Just a follow up question, I can't complete the second part of the challenge when I put,
#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"],
[UIImage imageNamed:@"02"],
[UIImage imageNamed:@"03"], nil];
self.ImageView.animationDuration = 5f;
}
@end
I get the error Bummer! You need to set the property of the duration of your animation on the 'imageView'.
I can't understand where I have gone wrong.
My THViewController.h looks like
#import "UIViewController.h"
@interface THViewController : UIViewController
@property (nonatomic, strong) UIImageView *imageView;
@end

9,409 PointsYou capitalized the "i" in imageView and it is not in brackets
self.imageView.animationDuration = 5.0f;
