请帮忙
- 我看不到您在代码中设置按钮的位置。什么是 cell.numberButton，什么是 cell.signButton？
使用
|
1
|
[tableView dequeueReusableCellWithReuseIdentifier:@“playerCell” forIndexPath:indexPath];
|
而不是
|
1
|
[tableView dequeueReusableCellWithIdentifier:@“playerCell”];
|
- 那个解决的图标没有出现，但它显示在不同的地方？
-
我已经开始缓存单元格来解决这个问题。我会将此标记为正确答案
-
谢谢。一切顺利 ！！
