1.去除多余的空白单元格
//去除多余的空白行
UIView *view = [UIView new];
view.backgroundColor = [UIColor clearColor];
[tableView setTableFooterView:view];
[view release];
2.选中单元格后的反显颜色即刻消失
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
//[tableView deselectRowAtIndexPath:indexPath animated:YES];//选中后的反显颜色即刻消失
。
。
}
3.让tableView定位到最下边一行
if ([self.array count]>1) {
//让tableView定位到最下边一行
NSIndexPath* indexPath = [NSIndexPath indexPathForRow:[self.array count]-1 inSection:0];
[self.myTableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionBottom animated:NO];
}
4.tableview刷新指定行
NSIndexPath *indexPath=[NSIndexPath indexPathForRow:currentCommentId inSection:0];
NSArray *array=[[NSArray alloc] initWithObjects:indexPath, nil];
//tableview刷新指定行,指定的行数应该放到一个array中,提供给该方法
[myTableView reloadRowsAtIndexPaths:array withRowAnimation:UITableViewRowAnimationMiddle];
5.定制选中单元格后的颜色
UIView *cellSelectedBackview=[[UIView alloc] initWithFrame:cell.frame];
cell.selectedBackgroundView=cellSelectedBackview;
[cellSelectedBackview release];
cell.selectedBackgroundView.backgroundColor=COLOR_WO_BACK;
6.增加cell
//先更新数据
//更新ui(无需手动更新ui,insert会自动执行reloadData)
NSIndexPath * indexPath = [NSIndexPath indexPathForRow:0 inSection:sender.tag];
[self.myTableView insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
7.删除cell(利用动画,比较简单的方式)
[CATransaction begin];
[CATransaction setCompletionBlock:^{
// animation has finished
[_myTableView reloadData];
}];
// do some work
[_myTableView beginUpdates];
//先更新数据
[_insurancePeopleArray removeObjectAtIndex:deleteIndex];
//更新ui
NSIndexPath * indexPathOld = [NSIndexPath indexPathForRow:deleteIndex-10 inSection:0];
NSArray *array=[NSArray arrayWithObjects:indexPathOld, nil];
[self.myTableView deleteRowsAtIndexPaths:array withRowAnimation:UITableViewRowAnimationFade];
[_myTableView endUpdates];
[CATransaction commit];
