Thanks in Advance.

回答1:

globally declare these variables

BOOL isSelectedAll;
NSMutableArray *arraySelectedRows;
int allDataCount; // this may be your arrayWithData.count

in 'viewDidLoad'

isSelectedAll = NO;
allDataCount = 10;
arraySelectedRows = [[NSMutableArray alloc]init];

in 'cellForRowAtIndexPath'

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//    UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:@"ce" forIndexPath:indexPath];
CustomTableViewCell *cell = [[CustomTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:@"cee"];
cell.textLabel.text = @"Test";
UIButton *buttonSelection = [[UIButton alloc]initWithFrame:CGRectMake(tableView.frame.size.width - 100, 8, 50, 50)];
buttonSelection.tag = indexPath.row;
if(isSelectedAll)
{
    [buttonSelection setImage:[UIImage imageNamed:@"tick"] forState:UIControlStateNormal];//Rename imageName as yours
}
else if([arraySelectedRows containsObject:indexPath]&&indexPath.row!=0)
{
    [buttonSelection setImage:[UIImage imageNamed:@"tick"] forState:UIControlStateNormal];//Rename imageName as yours
}
else
{
    [buttonSelection setImage:[UIImage imageNamed:@"untick"] forState:UIControlStateNormal];//Rename imageName as yours
}

[buttonSelection addTarget:self action:@selector(selectionButtonAction:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:buttonSelection];
return cell;
}

in 'didSelectRowAtIndexPath'

- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:     (NSIndexPath *)indexPath
{
if (indexPath.row == 0)
{
    //select all button
    if (isSelectedAll)
    {
        isSelectedAll = NO;
        [arraySelectedRows removeAllObjects];
    }
    else
    {
        [arraySelectedRows removeAllObjects];
        for (int i = 1; i<allDataCount; i++)
        {
            [arraySelectedRows addObject:[NSIndexPath indexPathForRow:i inSection:0]];//section number may be defer for you
        }
        isSelectedAll = YES;
    }
}
else
{
    if([arraySelectedRows containsObject:indexPath])
    {
        [arraySelectedRows removeObject:indexPath];

    }
    else
    {
        [arraySelectedRows addObject:indexPath];
    }
    if ((allDataCount - 1) == arraySelectedRows.count)
    {
        isSelectedAll = YES;
    }
    else
    {
        isSelectedAll = NO;
    }
}
[self.tableView reloadData];
}

if you need to do the same thing in button action

-(void)selectionButtonAction:(UIButton*)button
{
if (button.tag == 0)
{
    //select all button
    if (isSelectedAll)
    {
        isSelectedAll = NO;
        [arraySelectedRows removeAllObjects];
    }
    else
    {
        [arraySelectedRows removeAllObjects];
        for (int i = 1; i<allDataCount; i++)
        {
            [arraySelectedRows addObject:[NSIndexPath indexPathForRow:i inSection:0]];//section number may be defer for you
        }
        isSelectedAll = YES;
    }
}
else
{
    NSIndexPath *buttonIndexPath = [NSIndexPath indexPathForRow:button.tag inSection:0];//section number may be defer for you
    if([arraySelectedRows containsObject:buttonIndexPath])
    {
        [arraySelectedRows removeObject:buttonIndexPath];

    }
    else
    {
        [arraySelectedRows addObject:buttonIndexPath];
    }
    if ((allDataCount - 1) == arraySelectedRows.count)
    {
        isSelectedAll = YES;
    }
    else
    {
        isSelectedAll = NO;
    }
}
[self.tableView reloadData];
}

The 'arraySelectedRows' contain selected row's indexPath

Please try this method

-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    MessageViewCell *cell =(MessageViewCell *)[tableView dequeueReusableCellWithIdentifier:@"cell"];
    if(cell == nil)
    {
        NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"MessageViewCell" owner:self options:nil];
        cell = [nib objectAtIndex:0];
    }
    cell.selectionStyle = UITableViewCellSelectionStyleNone;

    cell.lblUsername.text  = [arrUsername objectAtIndex:indexPath.row];

    NSURL *URL =[NSURL URLWithString:[NSString stringWithFormat:@"%@%@",_URL_IMAGEURL,[arrImages objectAtIndex:indexPath.row]]];

    cell.imgView.tag = indexPath.row;

    UITapGestureRecognizer *tap1 = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(openProfile:)];

    tap1.numberOfTapsRequired = 1;

    cell.imgView.userInteractionEnabled = YES;

    [cell.imgView addGestureRecognizer:tap1];

    cell.imgView.image = [UIImage imageNamed:@"NoImage.png"];

    [[AsyncImageLoader sharedLoader] cancelLoadingImagesForTarget:cell.imgView];

    cell.imgView.imageURL = URL;

    cell.imgView.layer.cornerRadius = cell.imgView.frame.size.width/2;

    [cell.imgView setClipsToBounds:YES];

    cell.btnCheckBox.tag = indexPath.row;

    [cell.btnCheckBox setHidden:false];

    if([[[arrFriends objectAtIndex:indexPath.row] valueForKey:@"markedToDelete"] boolValue]){
        [cell.btnCheckBox setSelected:TRUE];
    }else{
        [cell.btnCheckBox setSelected:FALSE];
    }


    [cell.btnCheckBox addTarget:self **action:@selector(checkBoxClick:)** forControlEvents:UIControlEventTouchUpInside];

    cell.lblMsg.text = [arrLastMessage objectAtIndex:indexPath.row];

    return cell;
}
/////
-(void)checkBoxClick:(UIButton *)sender
{
    UIButton *btn = (UIButton *)sender;
    NSIndexPath *indexPath = [tblMessages indexPathForCell:(UITableViewCell *)btn.superview.superview];
    [sender setSelected:!sender.isSelected];
    if (sender.isSelected)
    {
        arrFriends[sender.tag][@"markedToDelete"] = @YES;
        if(![arrDeleteUsername containsObject:[arrOppUsername objectAtIndex:indexPath.row]])
        {
            [arrDeleteUsername addObject:[arrOppUsername objectAtIndex:indexPath.row]];
        }
    }
    else
    {
        [arrDeleteUsername removeObject:[arrOppUsername objectAtIndex:indexPath.row]];
        arrFriends[sender.tag][@"markedToDelete"] = @NO;
    }
}

回答3:

Your code for button click action does not look to do any thing. Just add the following code to your project and it should work:

- (void)doneBtn:(UIButton*)sender{
if ([sender tag]==0)
{
    if (selectAll==0)
    {
        selectAll=1;
        [self.arrForIndPaths removeAllObjects];
    }
    else
    {
        selectAll=0;
        [self.arrForIndPaths removeAllObjects];
    }
}
else
{
    if (selectAll!=1)
    {
        if([self.arrForIndPaths containsObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]])
        {
            [self.arrForIndPaths removeObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]];
        }
        else
        {
            [self.arrForIndPaths addObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]];
        }
    }
    else
    {
        selectAll=0;
        if([self.arrForIndPaths containsObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]])
        {
            [self.arrForIndPaths removeObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]];
        }
        else
        {
         [self.arrForIndPaths addObject:[NSIndexPath indexPathForRow:[sender tag] inSection:0]];
        }
       }
    }
[tableView reloadData];
}

Or make the changes accordingly.
