objective c - Ownership modifiers with manual reference counting -

what happens when use objective-c onwership modifiers ( __strong, __weak, __unsafe_unretained ) manual reference counting? of them modify behavior of ignored? clang -e -dm shows definitions of built-in macros: $ clang -e -dm -x objective-c /dev/null | egrep "weak|strong|unsafe" #define __strong #define __unsafe_unretained #define __weak __attribute__((objc_gc(weak))) as can see, __strong , __unsafe_unretained defined empty macros, , __weak defined (as understand it) relevant in (no longer supported) garbage-collected environment. so in short: ownership modifiers ignored manual reference counting. makes sense because your responsibility maintain reference counts. the situation different properties: @property(strong) id x; // same "retain" @property(weak) id y; // syntax error mrc @property(unsafe_unretained) id z; // same "assign" and sake of completeness: arc ownership modifiers built-in macros de...
