How to detect where the on demand resources are located after being downloaded?

回答1:

Unless you specified a bundle when you initialized the resource request, the resources are placed in the main bundle by default. So for example, you could access them this way, if appropriate to your type of resource:

NSString *path= [[NSBundle mainBundle] pathForResource:@"movie" ofType:@"mp4"  ];

Finally I've found, how to get a path of on demand resources location:

func preloadResourcesWithTag(tagArray: Array<Any>, resourceName: String ){

    let tags = NSSet(array: tagArray)
    let resourceRequest:NSBundleResourceRequest = NSBundleResourceRequest(tags: tags as! Set)
    resourceRequest.beginAccessingResources { (error) in
        OperationQueue.main.addOperation{
            guard error == nil else {
                print(error!);
                return
            }

                print("Preloading On-Demand Resources ")

            let _path1 = resourceRequest.bundle.path(forResource: "img2", ofType: "jpg")
            let img = UIImage(contentsOfFile: _path1!)}

So, the real location of on demand resources is here:

/Users/admin/Library/Developer/CoreSimulator/Devices/250101ED-DFC5-424C-8EE1-FC5AD69C3067/data/Library/OnDemandResources/AssetPacks/com.ae.OfflineMapSwiftV1/1629348341761109610/com.##.OfflineMapSwiftV1.asset-pack-000000G31NNOJ.assetpack/img2.jpg

To expand upon saswanb's answer, the pathForResource you use has to match the folder or filename you added to the ODR tag. If you add a reference to a folder to an ODR, you can search for that folder name, but not the contents of the folder.

NSString *path= [[NSBundle mainBundle] pathForResource:@"ODRFolder1" ofType:nil  ];

But if you add the contents of the folder to the ODR tag, then you can search for each file individually.
