问题
I'm using [NSData dataWithContentsOfURL:] to create two NSData instances and I want to compare these instances to gauge how different they are. Since they're both from the same website, using a string to find what is different will help me highlight the actual element(s) that has (have) changed. Is it possible to change this data to a string to find the difference?
回答1:
Try initWithData:encoding: method of NSString to create string with your data.
Exmp: NSString *str = [[NSString alloc] initWithData:someData encoding:NSUTF8StringEncoding]
回答2:
Why don't you use NSString stringWithContentsOfURL:encoding:error:
