-(NSString*) stringExample
{
	// You prepend a string with @ to indicate to the objective-c compiler that it's an NSString.
	// Release messages (see above) aren't required for these and are ignored.
	NSString *result = @"initial";

	// Strings are immutable as in .NET, however not interned so the same
	// string can exist in two memory locations. There is a subclass of
	// NSString called NSMutableString which is akin to a StringBuilder.
	result = [result stringByAppendingString:@" test"];
	return result;
}

-(NSString*) stringFormatExample : (NSString*) title : (NSString*) firstName
{
	// This is the equivalent in C# of 'return firstname + " " + firstName;' or the String.format equivalent
	// As far as I know, there is no way of concatenation without using formatting.
	// %@ is the string format to print an object, like {0}. The overriden description
	// method controls the output for an object, which is demonstrated below.
	NSString *result = [NSString stringWithFormat: @"%@ %@",title,firstName];
	return result;
