In Objective-C we can easily read and write text files by using the NSString class methods, and the way we do that is as follows:
NSString *fileContent = [NSString stringWithContentsOfURL:url encoding:NSUTF8StringEncoding error:nil];
where url is the location of our actual file.
NSUTF8StringEncoding parameter is an Enum values specified by the system and it is widely used for .txt files.
To write strings/text to files we use the following syntax:
[newFileContent writeToURL:
url atomically:YES encoding:NSUTF8StringEncoding error:nil];
where newFileContent is an object of NSString class, "atomically:YES" means that the system will first create a temporary file, and if everything executes successfully, it will rename that to the file in our url.
