我一直在尝试填充我的tableView for the 4天，我一直在努力。
我在这里已经完成了一些问题，并尝试了其他人给出的一些建议，但似乎都没有。基本上我从我的网站发送了JSON数据，并填充了一个数组，然后我希望将其放入tableView中。
NSLog返回所有正确的信息，但似乎在创建数组后停止，并且在数组填充后没有任何数据记录。
这是我的.h文件

您尚未初始化您的uitableviewcell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = @"Cell";
UITableViewCell *cell =[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
答案 1 :(得分：0)
我认为您需要在setupReportsFromJSONArray方法的末尾而不是didReceiveResponse中调用reloadData，因为在此之前您不创建reportsArray。
