通按钮两个参数点击（访问按钮点击两个字符串）

Question

我是一个新的程序员的我的手机

我有一个小问题....我想传递两个参数按钮点击....

//---insert individual row into the table view--- 

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

    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:[NSString stringWithFormat:@"Cell %i",indexPath.section]]; 

    if (cell == nil) { 

     cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:[NSString stringWithFormat:@"Cell %i",indexPath.section]] autorelease]; 

    } 


    cell.selectionStyle = UITableViewCellSelectionStyleNone;//my code.... change the color or selected cell 



    search_items *pro = [searchCount objectAtIndex:[indexPath row]]; 


     NSString *string1=[[NSString alloc]init]; 
    NSString *string2=[[NSString alloc]init]; 


     /// i wants access these two strings on buttonClicked Method...(pass as a argument):) 

    string1=pro.s_showroomName; 

     string2=pro.s_productName; 


     UIButton* aButton = [UIButton buttonWithType:UIButtonTypeRoundedRect]; 

    aButton.frame = CGRectMake(150, 15,150,40); 

    [aButton setTag:indexPath.row]; 

     [aButton addTarget:self action:@selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside]; 

     [cell.contentView addSubview:aButton]; 

    UIImage *img = [UIImage imageNamed:@"image.png"]; 

     [aButton setImage:img forState:UIControlStateNormal]; 

     [aButton setTitle:@"View Details" forState:UIControlStateNormal]; 

    [aButton addSubview:buttonLabel1]; 


    NSString *filepath=[[NSBundle mainBundle]pathForResource:pro.s_image ofType:@"png"]; 

     UIImage *image=[UIImage imageWithContentsOfFile:filepath]; 



    cell.imageView.image=image; 



    return cell; 
} 

-(void)buttonClicked:(UIButton*)sender { 

    //int tag = sender.tag; 


}

一个简单的方法从按钮来访问你的细胞，在按钮的回调是要求它为它的上海华盈的上海华：

-(void)buttonClicked:(UIButton*)sender { 

    //int tag = sender.tag; 
    UIView* contentView = [sender superview]; 
    if ([[contentView superview] isKindOfClass:[UITableViewCell class]] == NO) { 
     NSLog(@"Unexpected view hierarchy"); 
     return; 
    } 
    UITableViewCell* cell = (UITableViewCell*)[contentView superview]; 

} 

您还可以根据按键的框架上，找出它是哪个细胞渴望在桌子上看。您需要将按钮的框架转换为表格视图（UIView有方法进行转换）。

默认的UITableViewCell对象有一个为textLabel和detailTextLabel，在你的cellForRowAtIndexPath方法，你可以设置自己的文字是这样的：

cell.textLabel.text = @"Some text"; 
cell.detailTextLabel.text = @"Some detail text"; 

那么你就可以访问你的回调，这些属性，当你已经获得的细胞。
