NSUser默認保存按鈕狀態並再次顯示

Question

我是iphone開發新手。我正在開發一個應用程序，我正在顯示一些聯繫人名稱與取消選中的圖像。一旦用戶點擊按鈕選擇意味着我將它存儲在nsuserdefaults中。這裏是我嘗試過的代碼。事實上，我的問題是另一個用戶值將動態變化。我爲所有進入tableview的用戶添加一個布爾值。如果在另一個用戶中添加一個人，我想要顯示處於關閉狀態。對於其他用戶，我必須存儲nsuserdefaults中存儲的值。第一次，我手動循環0在總用戶。

正好與此代碼嘗試cellForRowAtIndexPath:方法

對於CustomCell使用像波紋管..

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

    MyViewCell *cell = (MyViewCell *) [tableView dequeueReusableCellWithIdentifier:nil]; 

    // MyCustomeCell *cell = (MyCustomeCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];//custom cell 
    // UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; 
    if (cell == nil) 
    { 
     NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:@"MyViewCell" owner:self options:nil]; 

     for (id currentObject in topLevelObjects){ 
      if ([currentObject isKindOfClass:[UITableViewCell class]]){ 
       cell = (MyViewCell *) currentObject; 
       break; 
      } 

     } 
} 

和DefaultCell使用婁代碼...

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kCustomCellID]; 
    if (cell == nil) 
    { 
     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:kCustomCellID] autorelease]; 
     cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator; 
     cell.selectionStyle=UITableViewCellSelectionStyleBlue; 
    } 
} 

我希望這對你有幫助..
