On iOS, is there a way to search ONLY subviews with a certain tag?

Question

Because right now, viewWithTag actually search for itself first, and then all subviews recursively down the whole subtree, for a view with that tag.

But wha

Answer 1

For 1 level:

UIView *view;
for (int i = 0; i < viewToSearch.subviews.count; i++){
    UIView *subview = viewToSearch.subviews[i];
    if (subview.tag == tagToSeach){
        view = subview;
        break;
    }
}

To search a view hierarchy with multiple levels:

__block UIView *view;
BOOL (^__block searchViewForTag)(UIView *,NSInteger) = ^(UIView *aView, NSInteger tag){
    for (UIView *subview in aView.subviews){
        if (subview.tag == tag){
            view = subview;
            return YES;
        }
        if (searchViewForTag(subview,tag)) return YES;
    }
    return NO;
};
NSInteger tagToSearchFor = 1;
searchViewForTag(viewToSearch,tagToSearchFor);

//Do something with view
