How do I convert HTML NSData to an NSString?
提问by Carter Pape
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?

Try initWithData:encoding:method of NSString to create string with your data.
尝试initWithData:encoding:使用 NSString 方法用您的数据创建字符串。
Exmp: NSString *str = [[NSString alloc] initWithData:someData encoding:NSUTF8StringEncoding]
例如： NSString *str = [[NSString alloc] initWithData:someData encoding:NSUTF8StringEncoding]
