NSFileManager creating folder (Cocoa error 513.)

Question

I\'m trying to create a folder inside the /sounds folder of my app.

-(void)productPurchased:(UAProduct*) product {
    NSLog(@\"[StoreFrontDelegate] Purchase         


        

Answer 1

I'm still not totally clear on the meaning of the 513 error in my case, but I was getting it when just trying to read an opened file URL using [NSFileHandle fileHandleForReadingFromURL:theUrl error:&err ].

I realized from this answer that with iOS 13, I now need to use startAccessingSecurityScopedResource to access external files that are opened in the app. When I wrapped my file calls as follows, then the error 513 stopped occurring:

if( [myURL startAccessingSecurityScopedResource] ) 
{
    NSFileHandle* myFile = [NSFileHandle fileHandleForReadingFromURL:myURL error:&err ];
    // ...Do file reads here...
    [theUrl stopAccessingSecurityScopedResource];
}
