段控制在iphone

Question

不工作我是一個新的國際展覽局，並使用分段controlller看錶，我的表更改，根據所選擇的片段......

這裏是代碼...而問題是，當我選擇任何segment..it沒有顯示我什麼..

- (void)viewDidLoad { 

segArrayOne = [[NSMutableArray alloc] initWithObjects:@"A",@"B",@"C",nil]; 
segArrayTwo = [[NSMutableArray alloc] initWithObjects:@"1",@"2",@"3",@"4",nil]; 
segArrayThree = [[NSMutableArray alloc] initWithObjects:@"A1",@"A2",@"A3",@"A4",@"A5",nil]; 
dummyArray = [[NSMutableArray alloc] init]; 

tableDummy = [[UITableView alloc] initWithFrame:CGRectMake(0,80,320,400) style:UITableViewStyleGrouped]; 
tableDummy.delegate = self; 
tableDummy.dataSource = self; 
// 
dummyArray=segArrayOne; 
[self.view addSubview:tableDummy]; 
tableDummy.scrollEnabled=NO; 

//[tableDummy release]; 
[segmentedController addTarget:self action:@selector(buttonPressed:) forControlEvents:UIControlEventValueChanged]; 


[super viewDidLoad]; 

}

-(IBAction)buttonPressed:(id)sender{ 

selectedSegment = [segmentedController selectedSegmentIndex]; 

switch (selectedSegment) { 
    case 0: 
     dummyArray=segArrayOne; 
     break; 
    case 1: 
     dummyArray=segArrayTwo; 
     break; 
    case 2: 
     dummyArray=segArrayThree; 

     break; 
    default: 
     //dummyArray=segArrayOne; 

     break; 
} 


NSLog(@"%@",dummyArray); 

}

- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { 
return 1; 

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { 
NSLog(@"%@",dummyArray); 

return [dummyArray count]; 
//return @""; 

}

   - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { 

static NSString *CellIdentifier = @"Cell"; 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
if (cell == nil) { 
    cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; 
     } 
cell.textLabel.text = [dummyArray objectAtIndex:indexPath.row]; 

return cell; 

}

在

-(IBAction)buttonPressed:(id)sender 

末或在情況下，如果你想呼叫[tableDummy reloadData]複製代碼並且不想在一箇中重載數據默認情況下。
