How to convert ASCII value to a character in Objective-C?

by

This is how you can work with ASCII values and NSString. Note that since NSString is working with unichars, there could be unexpected results for a non ASCII string.

// NSString to ASCII
NSString *string = @"A";
int asciiCode = [string characterAtIndex:0]; // 65

// ASCII to NSString
int asciiCode = 65;
NSString *string = [NSString stringWithFormat:@"%c", asciiCode]; // A
