ARC: “Pointer to non-const type 'id' with

2019-02-11 21:01发布

i am upgrading an iOS 4 project to use it with ARC with the sdk5. So i want to use the automatic refactor method for converting the code to use ARC. Unfortunately it does´t work. I get a lots of errors..

for(id* child in childObjectArray){
    [child removeParentGroupReferences];
}

That gives me the following error output:

Pointer to non-const type 'id' with no explicit ownership

Any help about that? What do i have to change? Thanks for any help..

id is a type, not an object. That means that id shouldn't be a pointer. Remove the * to fix it.

for(id child in childObjectArray){
    [child removeParentGroupReferences];
}

Change id* to id. id is already defined as an object pointer.
