can't read from file

[serbov]

I have some code:

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *path = [documentsDirectory stringByAppendingPathComponent:@"example.txt"];

NSString reValS;
NSInteger retVal;
retVal = [@"2" writeToFile: path atomically:YES];


it's write to file value =2 ; but I can't find anywhere - how can I read this value to reValS?

thanks!
