NSString retain Count

[itsaboutcode]

Hi,

Just couple of days i was working on a project and i have to see what is retain count of a string.

But it always return me "2147483647", Why it is so?

Check out this code to check it yourself.

PHP Code:

NSString *str = [[NSString alloc] initWithString:@"Hello World"];
NSLog(@"String Retain Count: %i", [str retainCount]); 


So my question is why it is not returning 1 like other objects return, why i am getting "2147483647"

Thanks in advance.

Because your string is not in the heap, but is a constant. A NSString made from a constant NSString is identical to the original NSString.

Don’t use non mutable objects to understand leak detection

Equality vs Identity
