Question

I have a NSMutableArray with the following objects:

  @interface MyViewCell : UITableViewCell {

    NSUInteger id;
    .....
  }

In some method I need quick search for the cell with predefined id. How the best to do that?

Answer 1

Probably the easiest way is to use - (NSUInteger)indexOfObjectPassingTest:(BOOL (^)(id obj, NSUInteger idx, BOOL *stop))predicate. See documentation here.

int index = [myArray indexOfObjectPassingTest: ^(id obj, NSUInteger idx, BOOL *stop) {
    MyViewCell *cell = (MyViewCell *)obj;
    BOOL result = (cell.id == someValue);
    stop = &result;
    return result;
}];
