Question

I want to create a file for my logs. But how can I continue on writing logs into one single file? For the first use I create the file and save my first log in it. But how can I continue on writing on this file without deleting the previous log messages?

Answer 1

NSFileHandle *h = [NSFileHandle fileHandleForWritingAtPath:@"MyFile.log"];
[h seekToEndOfFile];

// log
[h writeData:[@"Hello World! 2nd time" dataUsingEncoding:NSUTF8StringEncoding]];

// close when not needed anymore
[h closeFile];
