Question

I have a big plist file, I have a problem, when I do:

 [NSMutableDictionary dictionaryWithContentsOfFile:docDirPath];

I must waiting for some seconds before I can use the application. Is there some solution?

Thanks

Load the plist in another thread, GCD is perfect for this.

dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0);
dispatch_async(queue, ^{ [self.theDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:docDirPath];   });

If the class of the method that does this will not live until the plist read is complete you will need to wrap the block in a copy to Heap.

dispatch_async(queue, [[^{ [self.theDictionary = [NSMutableDictionary dictionaryWithContentsOfFile:docDirPath]; } copy] autorelease]);
