Ios 将数组传递给uitableviewcell时发生NSInvalidArgumentException

您好，我在将uitableview放入tableview单元格时遇到麻烦。当我尝试将其放入tableviewcell时

我为tableviewcell创建了一个新视图。我将uitableview放入单元格，为tableviewcell创建一个新类，并将其填充到表格中。但是我总是在[cell setNewsList:newsList]中出错；线路

MainViewController.m：

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

HorizontalTableCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSArray *item = self.news[indexPath.section];
NSMutableArray *newsList = [item valueForKey:@"news"];

水平表细胞.h：

#import <UIKit/UIKit.h>

@interface HorizontalTableCell : UITableViewCell

@property (nonatomic,strong) NSMutableArray *newsList;
@property (weak, nonatomic) IBOutlet UITableView *horizontalTableView;

@end

错误是，您试图在没有此类方法的UITableViewCell上调用setNewsList:。我猜您忘了将单元格的类更改为自定义类HorizontalTableCell。是的，在@rdelmar的评论中，似乎[tableView dequeueReusableCellWithIdentifier:CellIdentifier]返回的是UITableViewCell，而不是HorizontalTableCell。您是对的。我修好了。但必须说我现在是android开发者，正在学习ios。Eclipse比xcode更清楚地解释错误。

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.newsList count];
}

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

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];

if (cell == nil)
{
    cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}

cell.textLabel.text = [self.newsList[indexPath.row] valueForKey:@"baslik"];

return cell;
}
