I would like to implement some code, which changes footer text in one section of the tableView (in viewDidAppear
or viewWillAppear
method). But how can I do it?
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
doesn't fit my requirements (It changes only once, during load of the tableVi开发者_开发知识库ew, but I need to change the footer's text after text in tableView cell is changed.
-(CGFloat) tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section{
return 120;
}
-(NSString *) tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
if (section == 0) {
return @"Things We'll Learn";
} else {
return @"Things Already Covered";
}
}
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
[tableView reloadData];
}
Implement
viewForFooterInSection
and add yourtextField
there. Also make that textField a property.When you have finished editing you tableViewCells, implement the
textFieldDidEndEditing
method and assign necessary value to the textField of your footerView.Once your textField is set, use
[tableView reloadData]
to implement theviewForFooterInSection
again and it should work now.
Edit:
If you want to change the title of the Footer section after editing the UITableViewCell,
Set a global variable or use
NSUserDefaults
to indicate thattableViewCell
has been edited.self.tableView reloadData
right after edit.In the method
titleForFooterInSection
check for that variable (this would mean that tableView has been edited) and set the title accordingly.
- (UIView *)tableView:(UITableView *)tableView viewForFooterInSection:(NSInteger)section
{
if(section == 1)
{
// For Lable
UIView *view = [[[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.bounds.size.width, 40)] autorelease];
tableView.sectionHeaderHeight = view.frame.size.height;
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 10, view.frame.size.width - 20, 44)];
label.text = [self tableView:tableView titleForHeaderInSection:section];
label.font = [UIFont boldSystemFontOfSize:16.0];
label.shadowOffset = CGSizeMake(0, 1);
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.adjustsFontSizeToFitWidth = YES;
[label setLineBreakMode:NSLineBreakByTruncatingTail];
[label setNumberOfLines:0];
label.text = @“Your Text Here…..your Text Here”;
[view addSubview:label];
[label release];
return view;
}
return nil;
}
- (CGFloat)tableView:(UITableView *)tableView heightForFooterInSection:(NSInteger)section
{
if(section == 1)
{
return 60.0;
}
return 0;
}
