ios - __NSCFDictionary stringByDeletingPathExtension 崩溃

Question

我在从 Web 服务获取的 UITableView 中显示数据。在尝试将此数据添加到 UITableView 时，我遇到了一些奇怪的崩溃

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[__NSCFDictionary stringByDeletingPathExtension]: unrecognized selector sent to instance 0x7f9bc68530e0'

谁能告诉我这是什么错误。这是我的回应

<__NSCFArray 0x7fd2846dec80>(
{
    DISTANCE = "2677.2557594500167";
    POPULARITY = 0;
    PRICE = "";
    "bar_id" = 1;
    "event_id" = "";
    "event_name" = "";
    "is_following" = 0;
    "participant_count" = 0;
    "venue_address" = “abc”;
    "venue_image" = "http://dsfdsf.com/uploads/venue_icon/original/8PHHBUbASoZZXdQNOyqL1jKAmd08rowg.jpg";
    "venue_name" = "CLUB";
},
{
    DISTANCE = "2677.2557594500167";
    POPULARITY = 0;
    PRICE = "";
    "bar_id" = 2;
    "event_id" = "";
    "event_name" = "";
    "is_following" = 0;
    "participant_count" = 0;
    "venue_address" = “def”;
    "venue_image" = "http://dsfdsf.com/uploads/venue_icon/original/8PHHBUbASoZZXdQNOyqL1jKAmd08rowg.jpg;
    "venue_name" = “Club";
}
)

这就是我向 UITableViewCell 添加数据的方式

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
cell.lbl_eventName.text = [[arrayEventData valueForKey:@"venue_name"]objectAtIndex:indexPath.row];
}

Answer 1

试试这个:

cell.lbl_eventName.text = [[arrayEventData objectAtIndex:indexPath.row] valueForKey:@"venue_name"];
