Question

我在BOOl的每个部分使用TableView值。第一部分有静态数据，第二部分有动态数据。我想在部分的每一行中给出bool值。但我无法这样做，因为第二部分有动态数据。能否请您建议我如何将每个单元格的bool值设置为静态或动态。

这是我的代码。

BOOL zero,one,dynamic

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:
(NSInteger)section{
    if (section == 0) {
        return 2;
    }if (section == 1) {
        return  [myData count];
    }
    return nil;
}



 -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath{

if (indexPath.row == 0 && indexPath.section == 0) {

        [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
        cell.accessoryView.hidden = NO;
        zero = true;


    }if (indexPath.row == 1 && indexPath.section == 0) {
        one = true;

        [tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;
        cell.accessoryView.hidden = NO;

    }

if (indexPath.section == 2) {

      cell = [tableView cellForRowAtIndexPath:indexPath];
dynamic = true;
}
}

在上面的代码中，我希望{2}中的每一行都有BOOL值，请您建议我如何实现此功能？

谢谢。

有一个简单的技巧，比如你想用每个动态数据添加BOOL值，所以只需添加一个更多关键模型，并将默认值设置为0。

实施例： -

      NSArray *responseArray = responseObject; //WEB SERVICE RESPONSE

// Add web service data to model 

    [responseArray enumerateObjectsUsingBlock:^(NSDictionary *  _Nonnull obj, NSUInteger idx, BOOL * _Nonnull stop) {
        dataModel *data = [dataModel modelObjectWithDictionary:obj];
        data.isBOOLValue=@(0)
        [mydata addObject:objBillBorad];
    }];

或者还有另一种方式

就像每次从Web服务向mydata

添加数据时都可以添加一个简单的NSDictionary @ {@“isBoolValue”：@（0）}

我认为这可能会解决您的问题。

如果不是这样，请告诉我，如果您有任何问题，我会尽快解决。

这是table view中.m的完整实施。创建NSMutableArray并在用户点按单元格时添加数据。这会在用户点按某个单元格时显示section，row和您的bool值。看看这个。希望这对你有所帮助。

@interface ViewController ()

@end

@implementation ViewController
{
    NSMutableArray *holdingArray;
    Boolean _zero,_first,_dynamic;
}

- (void)viewDidLoad {
    [super viewDidLoad];

    holdingArray = [[NSMutableArray alloc] init];
    _zero = _first = _dynamic = FALSE;
    // Do any additional setup after loading the view, typically from a nib.
}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}


-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
    return 2;
}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    if(section == 0)
    {
        return 2;
    }
    else
    {
        return 10; // you can use you dynamic data here.
    }
}

-(NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
    if (section == 0) {
        return @"SECTION 0";
    }
    else
    {
        return @"SECTION 1";
    }
}

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    UITableViewCell *thecell = [tableView dequeueReusableCellWithIdentifier:@"mycell"];

    if(indexPath.section == 0)
    {
        //do your static data binding here
    }
    else
    {
        // do your dynamic data binding here
    }

    return thecell;
}


- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
    if (indexPath.section == 0)
    {
        //this means your static data section

        if(indexPath.row == 0)
        {
            //this is your zeroth row in zeroth section
            NSString *mysection = [NSString stringWithFormat:@"%ld",(long)indexPath.section];
            NSString *myrow = [NSString stringWithFormat:@"%ld",(long)indexPath.row];
            _zero = TRUE;

            NSString *addstring = [NSString stringWithFormat:@"Section :[%@] | Row :[%@] | Zero Value : [%@]",mysection,myrow,@"TRUE"];

            [holdingArray addObject:addstring];

        }
        else
        {
            //this is your first row in zeroth section
            NSString *mysection = [NSString stringWithFormat:@"%ld",(long)indexPath.section];
            NSString *myrow = [NSString stringWithFormat:@"%ld",(long)indexPath.row];
            _first = TRUE;

            NSString *addstring = [NSString stringWithFormat:@"Section :[%@] | Row :[%@] | First Value : [%@]",mysection,myrow,@"TRUE"];

            [holdingArray addObject:addstring];
        }


    }
    else
    {
        //this means your dynamic data section.

        NSString *mysection = [NSString stringWithFormat:@"%ld",(long)indexPath.section];
        NSString *myrow = [NSString stringWithFormat:@"%ld",(long)indexPath.row];
        _dynamic = TRUE;

        NSString *addstring = [NSString stringWithFormat:@"Section :[%@] | Row :[%@] | Dynamic Value : [%@]",mysection,myrow,@"TRUE"];

        [holdingArray addObject:addstring];
    }

    NSLog(@"selected cells details : %@", holdingArray);
}
