iOS: View ignoring touches but the ones inside its subviews

The "Request product button" was inside "Container view" so I was either unable to click on it or unable to scroll the collection view below the "Container view"

Solution:

Subclass UIView and assign that subclass class to "Container view" and implement the following:

- (UIView *)hitTest:(CGPoint)point withEvent:(UIEvent *)event

{

    UIView *hitView = [super hitTest:point withEvent:event];

    if (hitView == self) return nil;

    return hitView;

}

[super hitTest:point withEvent:event] will return the view touched that is the deepest in the view hierarchy.
