Writing a for loop in Objective C way

I have a doubts in writing a for loop in Objective C way. I can do the same loop in traditional C for loop, However I am trying to learn Objective C. Here is my question.
listdata is a mutable array holding objects of ofi_vc_modal_ab_user_info objects, I want to compare each email of list data with email until list data count and find its position and if found I want to delete the object from list data.

    for (ofi_vc_modal_ab_user_info *loc_obj in listData)
    {
        if (strcasecmp(loc_obj->email, email) == 0) {
           // What need to do here.
        }
    }

How to proceed here... thanks for your helps :)

BOOL foundObject = NO; 
ofi_vc_modal_ab_user_info *loc_found_obj = nil; 
for (ofi_vc_modal_ab_user_info *loc_obj in listData)
{
    if (strcasecmp(loc_obj->email, email) == 0) {
       // Set your flag here
       loc_found_obj = loc_obj;
        foundObject = YES;
        break;
    }
}
if(foundObject) {
// Do your stuffs as object is found
// Your found object is in loc_found_obj
 [listData removeObject:loc_found_obj];
}

I hope below code explains what you want. Please explain bit more if you need more help.

EDIT : If you are using NSMutableArray then you do not need index of the object. you can directly delete object as mentioned in my edited code.

you can just use C's for.

in fact, it's an error to mutate the collection you iterate over when using for (e in collection).
