iPhone reading file - strange behavior

so I've got a file called answers.txt which looks like this:

1:A
2:B
3:BC
......

so a bunch of lines separated by a new line

i use this code to get the lines into a NSArray:

NSStringEncoding encoding;
NSError* error;
NSString* myString = [NSString stringWithContentsOfFile:filePath usedEncoding:&encoding error:&error];  
NSArray *lines = [myString componentsSeparatedByString:@"\n"];

The file is written unix style, so the lines are separated by \n an开发者_如何转开发d not \r\n

Now for the problem:

When I build on the simulator, I get a correct array of lines if I split at \r\n and an incorrect array if I split at \n (I mean it does split at \n but then I split again every line at :, the second element has a newline at the end)

When I build on the device, it does exactly the opposite (it splits correctly at \n, and if I split at \r\n I get only one element - probably because there is no \r in the file)

Am I missing something here?

Pretty surprising that simulator and device have different behavior, but you can overcome the problem by using this:

[str componentsSeparatedByCharactersInSet:[NSCharacterSet newlineCharacterSet]];
