Problem with secondary delegate - iphone

Question

I have two UITableView, each one has a different delegate in the same UIViewController.
I'm trying to call control in another delegate, but it failed.
Brief:
mainViewController contains UITableView (with UITableViewDelegate and UITableViewDataSource) + UIImageView.
secondaryTable contains UITableView (with UITableViewDelegate and UITableViewDataSource).
I want to call UIImageView from secondaryTable.
In .h
#interface secondaryTable : UIViewController <UITableViewDataSource,UITableViewDelegate>
#end
#interface mainViewController : UIViewController <UITableViewDataSource,UITableViewDelegate> {
#property (nonatomic,retain) IBOutlet UIImageView *navbar;
#property (nonatomic,retain) IBOutlet UITableView *Table1;
#property (nonatomic,retain) IBOutlet UITableView *Table2;
#end
In .m
#implementation secondaryTable
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return 2;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"MyIdentifier2";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
[cell.textLabel setFont:[UIFont boldSystemFontOfSize:12.0]];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.textLabel.textAlignment = UITextAlignmentCenter;
}
if (indexPath.row == 0) cell.textLabel.text =#"A";
if (indexPath.row == 1) cell.textLabel.text =#"B";
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"Selected");
mainViewController *myController = [[mainViewController alloc] init];
[myController.navbar setHidden:NO];
}
#end
#implementation mainViewController
- (void)viewDidLoad {
Table1.delegate = self;
Table1.dataSource = self;
secondaryTable *myDelegate = [secondaryTable alloc];
Table2.delegate = myDelegate;
Table2.dataSource = myDelegate;
#end
}
It types "Selected" in console log, but it won't show control.
Why can't it call navbar control in mainViewController?

I would suggest doing this by having both tables point to the same delegate but, within your delegate methods, select behaviour based on which table it is. Example:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == firstTable)
{
// Do appropriate things here
}
else if (tableView == secondTable)
{
// do things for table #2 here
}
else
{
assert(no); // error checking
}
}
