Note: Not all data types are toll-free bridged, even though their names might suggest that they are. For example,NSRunLoop is not toll-free bridged to CFRunLoop,NSBundle is not toll-free bridged to CFBundle, andNSDateFormatter is not toll-free bridged to CFDateFormatter.

注意：并不是所有的类型都是对象桥接，尽管其名称让它们看上去很像。例如，NSRunLoop和CFRunLoop不能对象桥接，NSBundle和CFBundle不能对象桥接，NSDateFormatter和CFDateFormatter不能对象桥接等。
