任何人都可以帮助我，我是iOS开发的新手，我在我的代码中做错了。当我点击该行时，它应在其下方插入另一行。
这是我的代码
错误： reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (3) must be equal to the number of rows contained in that section before the update (3)

答案 0 :(得分：1)
你有这个问题，因为你需要在调用
时更改数据源（为新行添加一个对象）[[self tbldata] insertRowsAtIndexPaths:@[indexPath] withRowAnimation:UITableViewRowAnimationBottom];
请参阅docs

我更新了像dis
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (isTapped==NO) {
//isTapped=NO;
if (indexPath.section == 0 & indexPath.row==0) {
section=indexPath.section;
numOfRows=indexPath.row;
NSArray* indexPaths = [self indexPathsForSection:section withNumberOfRows:[self.data count]];
[self.tbldata beginUpdates];
[self.tbldata insertRowsAtIndexPaths:indexPaths withRowAnimation:UITableViewRowAnimationBottom];
[self.tbldata endUpdates];
}
}
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
-(NSArray*) indexPathsForSection:(NSInteger)section withNumberOfRows:(NSInteger)numberOfRows
{
NSMutableArray* indexPaths = [NSMutableArray new];
for (int i = 0; i < numberOfRows; i++) {
NSIndexPath* indexPath = [NSIndexPath indexPathForRow:i inSection:section];
[indexPaths addObject:indexPath];
}
return indexPaths;
}
