Note that this method only works with file paths (not, for example, string representations of URLs).
Example of [NSString stringByExpandingTildeInPath]
NSData *output1 = [NSData dataWithContentsOfFile:
[@"~/centralUtilOut.tmp" stringByExpandingTildeInPath]];
NSString *output = [[NSString alloc]initWithData:output1
encoding:NSUTF8StringEncoding];
NSLog(@"%@", output);
[output release];
Example of [NSString stringByExpandingTildeInPath]
NSError *err = nil;

filepath = [filepath stringByExpandingTildeInPath];
NSString *file = [NSString stringWithContentsOfFile:filepath
encoding:NSUTF8StringEncoding
error:&err];
