Accessing images from nsbundle

Question

I have a framework which is trying to access xib's and images from a bundle. I am able to access the xib fine but unable to load the images in UIImageView. I even check if the file exists and the console output is yes...

Any idea how to load the image?

Code to load xib in the framework viewcontroller file

self = [super initWithNibName:@"ViewController_iPad" bundle:[NSBundle bundleWithPath:[[NSBundle mainBundle] pathForResource:@"MyBundle" ofType:@"bundle"]]];

Code to load images

- (void) loadImage
{
    NSString *path = [[NSBundle mainBundle] pathForResource:@"MyBundle.bundle/test" ofType:@"png"];
    BOOL present = NO;
    present = [[NSFileManager defaultManager] fileExistsAtPath:path];
    if (present)
    {
        NSLog(@"MyBundle.bundle/test exists");
    }
    else
    {
        NSLog(@"MyBundle.bundle/test does not exists");

    }

    self.testImageView.image = [UIImage imageNamed:path];

    self.testImageView2.image = [UIImage imageWithContentsOfFile:path];
}

MyTestHarnessApp[11671:c07] MyBundle.bundle/test exists

Answer 1

When you use imageNamed: you must pass just a simple filename and the image must exist in the root of the app's resource bundle.

Your image is not in the root of the resource bundle, it is in a subfolder.

Since you have obtained the image's full path in the path variable, you must use the UIImage imageWithContentsOfFile: method:

self.testImageView.image = [UIImage imageWithContentsOfFile:path];

Answer 2

If +[UIImage imageNamed:] isn't resolving the path correctly, you could always use:

self.testImageView.image = [UIImage imageWithContentsOfFile: path];

Answer 3

You can just use the following:

self.testImageView.image = [UIImage imageNamed:@"MyBundle.bundle/test.png"];

But it seems that if you put the XIB in the bundle too, the interface will be relative to the bundle.

self.testImageView.image = [UIImage imageNamed:@"test.png"]

Answer 4

try going step by step.

First get the path to the bundle within your main bundle:

NSString *myBundlePath=[[NSBundle mainBundle] pathForResource:MyBundle ofType:@"bundle"];

Check to see if there is anything in the bundle. This is more for double checking. Once it is working you can choose to omit this code. But it is always a good idea to double check things.

 NSBundle *imageBundle=[NSBundle bundleWithPath: myBundlePath];
 NSArray *allImageURLs=[imageBundle URLsForResourcesWithExtension:@"png" subdirectory:nil];
 NSLog(@"imageURLS:  %@",allImageURLS);

Since you already have the bundle path add the image name to the path. Or you can just pull it from the list of urls that you already have in the above code.

NSString *myImagePath=[myBundlePath stringByAppendingPathComponent:@"test.png"];
NSLog(@"myImagePath=%@",myImagePath);

Then, since you have the full path, load the image

UIImage *testImage = [UIImage imageWithContentsOfFile:backgroundImagePath];

Code taken from shipping app.

Good Luck

If the images are already in the main bundle just use the image name: test.png or simply test

[UIImage imageNamed:@"test.png"];
[UIImage imageNamed:@"test"];
