Answer 1

NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents directory

NSError *error;
BOOL succeed = [myString writeToFile:[documentsDirectory stringByAppendingPathComponent:@"myfile.txt"]
      atomically:YES encoding:NSUTF8StringEncoding error:&error];
if (!succeed){
    // Handle error here
}
