objective-c - 使用未声明的标识符“单元格”

Question

我正在使用自定义表格单元，但是在我的 uilabel 中解析 JSON 时遇到问题，我正在使用下面的代码，这很好用。在我的 UILabel 中放一些东西我很简单

cell.One.text = @"xx"; 

/

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

    static NSString *CustomCellIdentifier = @"CustomCellIdentifier ";
    CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier];
    if (cell == nil) { 
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"CustomCell"
                                                     owner:self options:nil];
        for (id oneObject in nib) if ([oneObject isKindOfClass:[CustomCell class]])
            cell = (CustomCell *)oneObject;
    } 

    return cell;    

}

但是当我尝试解析我通常会做的事情时

- (void)fetchedData:(NSData *)responseData {


    NSError* error;
    NSDictionary* json = [NSJSONSerialization JSONObjectWithData:responseData //1
                                                         options:kNilOptions 
                                                           error:&error];
    NSArray* lastgame = [json objectForKey:@"items"]; 

    NSDictionary* game = [lastgame objectAtIndex:0];

    cell.One.text = [NSString stringWithFormat:@"%@",
                         [strijd objectForKey:@"One"]
                         ];
}

但是在这一行我收到一个错误：（使用未声明的标识符'cell'）现在有人如何修复thix？

cell.One.text = [NSString stringWithFormat:@"%@",
                             [strijd objectForKey:@"One"]
                             ];

Answer 1

cell.One.text = [NSString stringWithFormat:@"%@",
                         [strijd objectForKey:@"One"]
                         ];

您的单元格未在此方法中声明，您必须在cellForRowAtIndexPath:

在您声明您的单元格后：CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier: CustomCellIdentifier];
