UITableView和UISegmentedControl

我是iPhone开发的新手。我有一个UITableView有三个部分，每个部分有三个行。我有一个UISegmentedControl有三个索引。tableview最初是隐藏的。当我选择segmentIndex的任何索引时，它将显示带有三个部分的tableview。但我的问题是，当我选择分段控制则其显示的tableView的指标只有一个部分和另外两个部分是隐藏在tableView.How做到这一点请回答
这里是我的代码UITableView和UISegmentedControl

reloed表的表中的每一个部分都显示三段在我的tableview。但是我只想显示一个部分，另外两个部分是隐藏的。 – 2013-03-06 06:23:58

非常感谢。它按我的需要完美地工作。 – 2013-03-06 12:22:38

@parthpatel如果你确定这个，接受答案.... – Venkat 2013-03-06 13:33:43

我相信我明白你想要做什么，你想显示不同的表格视图单元取决于哪个按钮段被选中。

你需要让你的cellForRowAtIndexPath检查选中哪个段并返回正确的一组单元。

当用户更改分段按钮时，请使用changeSegment：将选定的段存储在实例变量中。然后让它调用[self reloadData];

它的小工第一次按钮段选中它的显示一段和其他隐藏但是第二次显示两段和第三次用三段选择按钮段显示表格我想每次按钮段选择其显示只有一个部分和其他两个隐藏 – 2013-03-06 06:59:34

感谢它也正在工作炉排。 – 2013-03-06 12:51:40

@parthpatel不客气。如果这是您在程序中使用的代码，请将此答复标记为您的问题的答案。 – 2013-03-06 19:43:41

试试这个

{ 
return 1; 
} 

-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section 
{ 
switch (sgmtControl.selectedSegmentIndex)

    case 0: 
     return 3; 
     break; 
    case 1: 
     return 3; 
     break; 
    case 2: 
     return 3; 
     break; 
} 
return 0; 
} 

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section 
{ 
switch (sgmtControl.selectedSegmentIndex) 
{ 
    case 0: 
     return @"FirstName"; 
     break; 
    case 1: 
     return @"MiddleName"; 
     break; 
    case 2: 
     return @"LastName"; 
     break; 
    } 
} 

    -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
static NSString *myIdentifier = @"MyIdentifier"; 

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:myIdentifier]; 
if (cell == nil) 
{ 
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:myIdentifier]; 
} 

switch (sgmtControl.selectedSegmentIndex) 
{ 
    case 0: 
     cell.textLabel.text =[firstName objectAtIndex:indexPath.row]; 
     break; 
    case 1: 
     cell.textLabel.text = [middleName objectAtIndex:indexPath.row]; 
     break;
