**NSString** *path = @"~"; **NSString** *absolutePath = [path **stringByExpandingTildeInPath**]; **NSLog**( [@"My folder is at'" **stringByAppendingString**:absolutePath]); // or just use this **NSLog**( @"My folder is at'%@'", absolutePath);

Also note that NSString cannot be modified once you have initialized it. Use NSMutableString if you need modify a string.

**NSMutableString** *logString = [[**NSMutableString** alloc] **initWithString**: @"Process Name: '"]; [logString **appendString**: [[**NSProcessInfo** processInfo] **processName**]]; [logString **appendString**: @"' Process ID: '"]; [logString **appendFormat**: @"%d", [[**NSProcessInfo** processInfo] processIdentifier]]; //cast int into string [logString **appendString**: @"'"];

NSLog(logString);

output:

2008-11-01 20:15:26.107 Assignment1b[1301:10b] Process Name: 'Assignment1b' Process ID: '1301'
