how to cast or set an object of type id to another type like UIImageView or UIView

Question

In the below code, I iterate through entries and they might be of type UIView or UIImageView. I want to do check if the uiComponent is of either the mentioned types, and then I want to proceed using that uiComponent in the code based on Whether it is a UIView or UIImageView?

I rote the below code but I can’t use the pointer object

uiComponent

After having it typed-casted??

Please let me know how to type the uiComponent object to either of the classes UIView or UIImageView and proceed programming using it

Code

 for (id uiComponent in uiviews) {
            UIView *uiView;
            UIImage *uiImageView;

         if ([AQSViewHelper isEntryOfTypeUIView:uiComponent]) {
                uiComponent = (UIView *)uiComponent;
         }
            if ([AQSViewHelper isEntryOfTypeUIImageView:uiComponent]) {
            uiComponent = (UIImageView *)uiComponent;
        }

         if (![uiComponent isHidden]) {
            …
    ..
    …
            }

Set your local object based on the type, then use it if it's not nil:

for (id uiComponent in uiviews) {
    UIView *uiView;
    UIImageView *uiImageView;

    if ([AQSViewHelper isEntryOfTypeUIView:uiComponent]) {
        uiView = (UIView *)uiComponent;
    }
    if ([AQSViewHelper isEntryOfTypeUIImageView:uiComponent]) {
        uiImageView = (UIImageView *)uiComponent;
    }

    if (uiView) {
        // do what you want because it's a UIView
        if ([uiView isHidden]) {
            // ...
        }
        // etc ...
    }
    if (uiImageView) {
        // do what you want because it's a UIView
        if ([uiImageView isHidden]) {
            // ...
        }
        // etc ...
    }
}

Or, since you are already in if blocks, you can do it there:

for (id uiComponent in uiviews) {
    if ([AQSViewHelper isEntryOfTypeUIView:uiComponent]) {
        // do what you want because it's a UIView
        UIView *uiView = (UIView *)uiComponent;
        if ([uiView isHidden]) {
            // ...
        }
        // etc ...
    }
    if ([AQSViewHelper isEntryOfTypeUIImageView:uiComponent]) {
        // do what you want because it's a UIImageView
        UIImageView *uiImageView = (UIImageView *)uiComponent;
        if ([uiImageView isHidden]) {
            // ...
        }
        // etc ...
    }
}
