Build Custom Object for iPad in Interface Builder

I need a custom object (UIScheduleBar) built for the iPad that shows a visual representation of a schedule free/busy time between 8 AM - 5 PM. Please see attached image. The custom object needs to have a "schedule" property that takes an array of "Start Time - End Time" objects, and instantly redraws the new schedule. Typical usage in code: In .h file: ----------- UIScheduleBar *scheduleBar; ... @property (nonatomic, retain) IBOutlet UIScheduleBar *scheduleBar; In .m file: ----------- NSMutableArray *scheduleArray = [NSMutableArray array]; [scheduleArray addObject:[[Event alloc] initWithStartTime:startTime1 EndTime:endTime2]]; [scheduleArray addObject:[[Event alloc] initWithStartTime:startTime2 EndTime:endTime2]]; ... // This call instantly updates the graphic area with the new schedule: scheduleBar.schedule=scheduleArray; We also have: @interface Event: NSObject { NSDate *startTime; NSString *endTime; } I need to be able to create this custom object in my View either programmatically or from Interface Builder. Please let me know if you have any questions.
