Button in custom cell and reloading parent tableview

I have tableViewController and RSS feeds loaded in the tableView. I want to implement "header like" cell (of type OrderCell.h/.m) with "order by date" and "order by popularity" custom 开发者_如何学JAVAbuttons that reorder rssItems array and refresh the table view when pressed.

How can I refresh the tableView from OrderCell object method? I have no problem reordering the rssItems array because I defined it as a static var with static methods available from outside the class TableViewController. My problem is calling [xxx.tableView reloadData]; when a user clicks a button "order by". Since OrderCell object is instantiated from TableViewController object how can I call the reload method of TableViewController object?

Thanks in advance, Luka

You could define your own protocol which will be implemented (Confirmed) by the TableViewController class ,

In myTableClass.h

@protocol AppDelegate

-(void) OrderSelected ;

@end

@interface myTableClass : UITableViewController <AppDelegate> 
{
  .......
}
@end

In OrderCell.h

@interface OrderCell : .....
{
  id<AppDelegate> myDelegate;
}
@property(nonatomic,assign)  id<AppDelegate> myDelegate;;
@end

In OrderCell.cpp

@synthesize myDelegate;

-(void) myButtonAction:(id) sender
{
   [myDelegate OrderSelected]; 
}

and

In myTableClass.cpp

When you create the OrderCell just write the Online Statement

myOrderCell.myDelegate = self;

and implement the protocol function

-(void) OrderSelected 
 {
   [self.tableView reloadTable];
 }

add delegate in you other class for you table view controller first and assign your current tableview controller to that delegate and in your table view controller add a method like

 -(void) updateTableItems {
    [self.table reloadData];
}


-(void) threadLoop { 

[self performSelectorOnMainThread:@selector(updateTableItems) withObject:nil waitUntilDone:NO];

}

now using delegate of other class call threadLoop of your table view controller, good luck
