[Original] common tableView BUG, tableviewbug

1. The TableView header view does not move with the view, and the header view is misplaced.

Error cause: the UITableViewStyle of tableView is not explicitly declared.

 

Solution: UITableViewStyleGrouped is specified when tableView is declared.

 

2. Adjust the white space height at the top of the group table View

Implementation Method:

Method 1 (recommended ):

Swift:

func tableView(tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {    if section == 0 {        return CGFloat.min    }    return tableView.sectionHeaderHeight}

Obj-C:

 - (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{    if (section == 0)        return CGFLOAT_MIN;    return tableView.sectionHeaderHeight;}

Method 2:

InloadView

_tableView.sectionHeaderHeight = 0;

Then

-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section{    return 0;}

 

Method 3:

- (void)viewWillAppear:(BOOL)animated{    CGRect frame = self.tableView.tableHeaderView.frame;    frame.size.height = 1;    UIView *headerView = [[UIView alloc] initWithFrame:frame];    [self.tableView setTableHeaderView:headerView];}
