Answer 1

I dont fully understand the question, but you could try each time you are saving the text, first read the text already in the file then use the stringByAppendingString.For example, the code

NSString *begRainbow = @"Red orange yellow green";
NSString *fullRainbow = [begRainbow stringByAppendingString:@" blue purple"];

Leaves fullRainbow with a value of "Red orange yellow green blue purple".
