Question

I’m reading a plist into my application, which consists of a root dictionary and a bunch of sub-values consisting of arrays and date objects. Here’s my code so far:

NSError *error;    
NSString *path = [[NSBundle mainBundle] pathForResource:@"Data" ofType:@"plist"];
NSData *plistData = [NSData dataWithContentsOfFile:path];
NSPropertyListFormat plistFormat;
plistValues = [NSPropertyListSerialization propertyListWithData:plistData options:NSPropertyListImmutable format:&plistFormat error:&error];

My question is: how can I tell when the NSData method dataWithContentsOfFile is done loading and…or when the NSPropertyListSerialization method is finished serializing the data? I don’t want to attempt to take the values from the load and assign them to variables until the plist is finished loading and those values actually exist and are serialized.

These are synchronous messages. They will block until they have the result.
