'Invalid update: invalid number of rows in section xx. The number of rows contained in an existing section after the update (xxx)...

'Invalid update: invalid number of rows in section 5.  The number of rows contained in an existing section after the update (299) must be equal to the number of rows contained in that section before the update (276), plus or minus the number of rows inserted or deleted from that section (0 inserted, 0 deleted) and plus or minus the number of rows moved into or out of that section (0 moved in, 0 moved out).'

 

我出现上面的这个错误是由于使用了这个函数刷新UITableView

- (void)reloadSections:(NSIndexSet *)sections withRowAnimation:(UITableViewRowAnimation)animation NS_AVAILABLE_IOS(3_0);

原先tableView只有4组数据, tableView中有后来增加到了6组数据, 但我刷新数据的时候还是刷新4组, 所以就出现了上面这个错误...
