Question

So, I’m currently saving images in my UIImageView via this method:

- (void)applicationDidEnterBackground:(UIApplication*)application {

    NSString  *image1 = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/image1.png"];
    NSString  *image2 = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents/image2.png"];
}

The images save just fine, but I have no idea how to set the UIImageViews images in viewDidLoad. This is what I’ve been trying:

- (void)viewDidLoad
{
    self.imageView.image =[UIImage imageNamed:[(NSHomeDirectory *)Documents objectForKey:@"image1"]];

    self.imageView2.image =[UIImage imageNamed:[(NSHomeDirectory *)Documents objectForKey:@"image1"]];
}

But, obviously that is not working. I’m having trouble understanding the basics here. Any help would be great, thanks!

Answer 1

The -imageNamed: method looks in the application’s main bundle if the named image hasn’t been cached yet. From the docs:

The name of the file. If this is the first time the image is being loaded, the method looks for an image with the specified name in the application’s main bundle.

(See UIImage class reference)

You want -imageWithContentsOfFile: instead.
