Checking asset existance of ALAasset in iOS.

Jayden Bell 1496 14 Jan 2016

I have an array of urls that contains ALAsset urls. I want to check existance of any specific url.
I tried this code:

NSData *assets = [[NSData alloc] initWithContentsOfFile:@"asset-library://asset/asset.PNG?id=0X32031&ext=JPG"];

but the nsdata variable assets is always nil. So, how can I solve this problem?

Here I am providing the code, which helps you to check existance of any specific url.
this is the code:

ALAssetsLibrary *assetLibrary = [[ALAssetsLibrary alloc] init];
[assetLibrary assetForURL:imageUrl resultBlock:^(ALAsset *asset){
 if(asset){
    NSLog(@"Image Exists");
    ALAssetRepresentation *assetRepresentation = [asset defaultRepresentation];
    UIImage *urlImage = [UIImage imageWithCGImage:[assetRepresentation fullResolutionImage]];
 } else {
    NSLog(@"Image Does't Exist");
 }
} failureBlock:^(NSError *error) {
 NSLog(@"Failure");
});
