iphone開發：使用tableview單元格作爲按鈕

Question

是否有可能像使用按鈕一樣使用tableView單元格？在我的應用程序中，我希望有一個有4行的表視圖，每行都會有標籤。我想要的是，當我觸摸一行時，table tableview單元格應該像按鈕一樣反應（執行一個動作並且背景突出顯示）？那可能嗎？我怎樣才能做到這一點？謝謝。

Answer 1

非常簡單的委託方法將被稱爲didSelectRowAtIndexPath那裏你可以得到哪一行被挖掘在哪個部分，你可以執行進一步的操作。

例如

-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { 
    // deselect 
    [tableView deselectRowAtIndexPath:indexPath animated:YES]; 

    if(indexPath.row == 0){ 
     LoginFormViewController *vController = nil; 
     if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad) 
     { 
      vController = [[LoginFormViewController alloc] initWithNibName:@"LoginFormViewController_ipad" bundle:nil]; 
     }else { 
      vController = [[LoginFormViewController alloc] initWithNibName:@"LoginFormViewController" bundle:nil]; 
     } 
     [self.navigationController pushViewController:vController animated:YES]; 
     [vController release]; 
    } 
} 

Answer 2

您可以實現在此的tableView「按鈕」功能：在您的UITableView委託didSelectRowAtIndexPath方法方法）

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath 
{ 
    // do something when pressed on an UITableViewCell 
} 

Answer 3

的CEL將突出，和你的表視圖的委託無論如何都會收到tableView:didSelectRowAtIndexPath:消息。你不需要任何額外的東西來實現你所描述的。

- (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.selectionStyle=UITableViewCellSelectionStyleGray; 

    } 



    if(tableView.tag==1) 
    { 
    cell.userInteractionEnabled = NO; 
    cell.backgroundColor =[UIColor blackColor]; 

    UIButton *Btn11=[UIButton buttonWithType:UIButtonTypeCustom]; 
    [Btn11 addTarget:self action:@selector(ratingAction:) forControlEvents:UIControlEventTouchUpInside]; 
    [Btn11 setBackgroundImage:[UIImage imageNamed:@"small_img4.png"] forState:UIControlStateNormal]; 
    Btn11.tag=indexPath.row; 
    Btn11.frame=CGRectMake(0, 6.5, 156, 74.5); 


     UILabel *Main_tblImg_Label=[[UILabel alloc]initWithFrame:CGRectMake(0, 80,156, 31)]; 
     [Main_tblImg_Label setBackgroundColor:[UIColor blackColor]]; 
     //[Main_tblImg_Label setText:@"First Drive 2012 Mercedes Benz M class"]; 
     //Main_tblImg_Label.textAlignment = UITextAlignmentCenter; 
     [Main_tblImg_Label setTextColor:[UIColor whiteColor]]; 
     [Main_tblImg_Label setFont:[UIFont fontWithName:@"Helvetica" size:9]]; 
     [Main_tblImg_Label setNumberOfLines:2]; 

     [cell.contentView addSubview:Main_tblImg_Label]; 
     [cell.contentView addSubview:Btn11]; 



     UILabel *other_Lbl=[[UILabel alloc]initWithFrame:CGRectMake(14, 80, 142, 29)]; 
     [other_Lbl setText:@"First Drive 2012 \nMercedes Benz M class"]; 
     [other_Lbl setBackgroundColor:[UIColor blackColor]]; 
     [other_Lbl setTextColor:[UIColor whiteColor]]; 
     [other_Lbl setFont:[UIFont fontWithName:@"Helvetica" size:9]]; 
     [other_Lbl setNumberOfLines:2]; 
     [cell.contentView addSubview:other_Lbl]; 
     [cell.contentView addSubview:Btn11]; 
       //[cell.contentView addSubview:Main_tblImg_Label]; 
//  [cell.contentView addSubview:Btn11]; 
//  







    UIButton *Btn22=[UIButton buttonWithType:UIButtonTypeCustom]; 
    [Btn22 addTarget:self action:@selector(ratingAction2:) forControlEvents:UIControlEventTouchUpInside]; 
    [Btn22 setBackgroundImage:[UIImage imageNamed:@"Screen2.png"] forState:UIControlStateNormal]; 
    Btn22.tag=indexPath.row; 
    Btn22.backgroundColor=[UIColor clearColor]; 
    Btn22.frame=CGRectMake(165, 6.5, 156, 74.5); 

     UILabel *main_tblImg_Lbl2=[[UILabel alloc]initWithFrame:CGRectMake(165, 80, 156, 31)]; 

     [main_tblImg_Lbl2 setBackgroundColor:[UIColor blackColor]]; 
     //[main_tblImg_Lbl2 setText:@"Audi planning Mexican Assembly plant?"]; 
     [main_tblImg_Lbl2 setTextColor:[UIColor whiteColor]]; 
     //[main_tblImg_Lbl2 setFont:[UIFont fontWithName:@"times" size:1]]; 
     [main_tblImg_Lbl2 setFont:[UIFont fontWithName:@"Helvetica" size:10]]; 
     [main_tblImg_Lbl2 setNumberOfLines:2]; 
     [cell.contentView addSubview:main_tblImg_Lbl2]; 


     UILabel *other1_Lbl=[[UILabel alloc]initWithFrame:CGRectMake(176, 80, 136, 31)]; 
     [other1_Lbl setText:@"Audi planning Mexican Assembly plant?"]; 
     [other1_Lbl setBackgroundColor:[UIColor blackColor]]; 
     [other1_Lbl setTextColor:[UIColor whiteColor]]; 
     [other1_Lbl setFont:[UIFont fontWithName:@"Helvetica" size:10]]; 
     [other1_Lbl setNumberOfLines:2]; 
     [cell.contentView addSubview:other1_Lbl]; 
     [cell.contentView addSubview:Btn11]; 


    [cell.contentView addSubview:Btn22]; 
    } 
return cell 
}
