Get UIImageView using Afnetworking and put it in an array - objective-c

Question

As the title says, i need to get the image and put it in an array.
UIImageView *myImage = [[UIImageView alloc] init];
[myImage setImageWithURL:[NSURL URLWithString:#"http://host.com/images/1/1.png"] placeholderImage:[UIImage imageNamed:#"page3.png"]];
[items addObject:myImage];
the problem is that while the image is being loaded, the code continues and nothing gets put in the array, actually I guess an empty UIImageView gets inserted.
How do I go about fixing this?
On a side note I am using iCarousel to display images, in the data source it gets the images array and shows them. Can i modify iCarousel somehow?
Thanks in advance.

You can use the setImageWithURLRequest method to give a success message or execute the UI update when it has finished for example using the following method:
- (void)setImageWithURLRequest:(NSURLRequest *)urlRequest
placeholderImage:(UIImage *)placeholderImage
success:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image))success
failure:(void (^)(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error))failure;
Here is an example (not tested)
[image setImageWithURLRequest:[NSURLRequest requestWithURL:[NSURL URLWithString:#"host.com/images/1/1.png"]] placeholderImage:[UIImage imageNamed:#"page3.png"]
success:^(NSURLRequest *request, NSHTTPURLResponse *response, UIImage *image){
//reload data here
}
failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error){
//handle errors here
}
