Do I need to release NSString generated using @“…”?

There are two ways to create an NSString obj in Objective C

Way 1:

// string1 will be released automatically 

NSString* string1 = [NSString string]; 

// must release this when done 

Way 2

NSString* string2 = [[NSString alloc] init]; 

[string2 release];

If I do

NSString *string = @"This is a string";

My question is which way an above declaration falls in and should we release it after all

Answer 1

String constants are not to be released; they’re neither explicitly to be released neither autoreleased; they’re simply constants and never deallocated.

So, only -release them if you previously retained them.
