ios - tableview 只执行numberOfRowsInSection,不执行cellForRowAtIndexPath代理方法

Question

tableview是用storyboard创建的，我在代码中执行[self.tableView reloadData];
执行numberOfRowsInSection的时候返回的值是 value > 0 的。但是不执行cellForRowAtIndexPath方法。

代理也已经设置好。

Answer 1

Is it true that the cellForRowAtIndexPath function is not used? You can stop and take a look. Is it possible that you didn’t notice that he was gone

Answer 2

Is [self.tableView reloadData] not written in the main thread?

Answer 3

Are you sure it is cellForRowAtIndexPath? If you take a closer look, you may be confused. There is another function that is very similar to this one

Answer 4

I happen to also encounter this problem, did you solve it? How to solve it?

Answer 5

Under what circumstances is data reloaded? If it is downloaded asynchronously, it must be returned to the main thread to refresh.
