Question

How to implement checkbox in tableview section header. my code is,

-(UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
    UIView *tempView=[[UIView alloc]initWithFrame:CGRectMake(0,200,300,244)];
    tempView.backgroundColor=[UIColor clearColor];

     UIButton *leftSecCheckBtn = [UIButton buttonWithType:UIButtonTypeCustom];
    [leftSecCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_empty.png"] forState:UIControlStateNormal];
    [leftSecCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkmark_Tick.png"] forState:UIControlStateSelected];
    [leftSecCheckBtn setFrame:CGRectMake(22,-2, 26, 26)];
    [leftSecCheckBtn addTarget:self
               action:@selector(leftSectionCheckBox:)
     forControlEvents:UIControlEventTouchUpInside];

-(void)leftSectionCheckBox:(id)sender
{   
    UIButton *selectedButton = (UIButton *) sender;
    {
        if([selectedButton isSelected ]==YES)
        {
            [selectedButton setSelected:NO];
        }

Answer 1

I think this could help:

-(void)leftSectionCheckBox:(UIButton *)sender  {  

sender.selected = !sender.isSelected;
if([selectedButton isSelected ]==YES)  [selectedButton setSelected:NO];
else  [selectedButton setSelected:YES];
}

or you can do this:

-(void)leftSectionCheckBox:(id)sender {  
for (UIButton * selectedButton in [[tableView headerViewForSection:0]subviews]) {
    if ([selectedButton isKindOfClass:[UIButton class]]) {
       if([selectedButton isSelected ]==YES) [selectedButton setSelected:NO];
       else  [selectedButton setSelected:YES];
      }
}}

Try this

    -(void)leftSectionCheckBox:(id)sender
    {   
        UIButton *selectedButton = (UIButton *) sender;

            if([selectedButton isSelected ]==YES)
            {
                [selectedButton setSelected:NO];
                [leftSecCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkbox_empty.png"] forState:UIControlStateNormal];
            }
            else
            {
                [selectedButton setSelected:YES];
                [leftSecCheckBtn setBackgroundImage:[UIImage imageNamed:@"checkmark_Tick.png"] forState:UIControlStateNormal];
            }
      }

I updated answer it one of the way. Otherwise you have to do it via interface builder.

Set your tempView user interaction enabled,

[tempView setUserInteractionEnabled:YES];

And you can minimize your method like,

-(void)leftSectionCheckBox:(UIButton *)selectedButton
{    
  selectedButton.selected = !selectedButton.selected;
}
