As in the Image I select Pass button

But when I reload the table selected button get unselect

how can I get the selected value when I reload the table.Thanks in Advance!

Answer 1

To much code.... You should post only code related to the problem. My guess, you set the view only and don't have variable responsible for this. When you reload table view you update the color and setup the default color. Simple solution - create Model that represents each cell. This model knows which buttons are selected etc.

edited: Example

class Model {

    var name: String?
    var isButtonOneSelected = false
    var isButtonTwoSelected = false
    var isButtonThreeSelected = false
    ....

}

In ios table view reuse the cell for every row so it does happen. You use model class for manage selection . I have add selectors on button on cell .And also example of reload table view. Please check below code.

//
//  ViewController.m

#import "ViewController.h"
#import "DataModel.h"
#import "MyTableViewCell.h"

@interface ViewController ()
{
    NSMutableArray *arrData;
}

@end

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];
    arrData = [[NSMutableArray alloc]init];

    // create 15 model and store in array
    for (int i =0; i<15; i++)
    {
        DataModel *model = [DataModel new];
        model.strSelected = @"";
        [arrData addObject:model];

    }

}

- (void)didReceiveMemoryWarning {
    [super didReceiveMemoryWarning];

}

- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
    return  arrData.count;
}


- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
    MyTableViewCell *cell = [self.tblView dequeueReusableCellWithIdentifier:@"cell" forIndexPath:indexPath];

    // tag add on buttons
    cell.btnPPressed.tag = indexPath.row;
    cell.btnFPressed.tag = indexPath.row;
    cell.btnWPressed.tag = indexPath.row;
    cell.btnNAPressed.tag = indexPath.row;

    //method add on buttons
    [cell.btnPPressed addTarget:self action:@selector(btnP:) forControlEvents:UIControlEventTouchUpInside];
    [cell.btnFPressed addTarget:self action:@selector(btnF:) forControlEvents:UIControlEventTouchUpInside];
    [cell.btnWPressed addTarget:self action:@selector(btnW:) forControlEvents:UIControlEventTouchUpInside];
    [cell.btnNAPressed addTarget:self action:@selector(btnNA:) forControlEvents:UIControlEventTouchUpInside];


    //background color change on button
    DataModel *model = [arrData objectAtIndex:indexPath.row];
    if([model.strSelected isEqualToString:@"P"])
    {
        cell.btnPPressed.backgroundColor = [UIColor redColor];
    }
   else if([model.strSelected isEqualToString:@"F"])
    {
        cell.btnFPressed.backgroundColor = [UIColor redColor];
    }
   else if([model.strSelected isEqualToString:@"W"])
   {
       cell.btnWPressed.backgroundColor = [UIColor redColor];
   }
   else if([model.strSelected isEqualToString:@"NA"])
   {
       cell.btnNAPressed.backgroundColor = [UIColor redColor];
   }
   else
   {
       cell.btnPPressed.backgroundColor = [UIColor darkGrayColor];
       cell.btnFPressed.backgroundColor = [UIColor darkGrayColor];
       cell.btnWPressed.backgroundColor = [UIColor darkGrayColor];
       cell.btnNAPressed.backgroundColor = [UIColor darkGrayColor];

   }


    return cell;
}


//buttons methods

-(void)btnP:(UIButton *)sender
{
    sender.backgroundColor = [UIColor redColor];
    DataModel *model = [arrData objectAtIndex:sender.tag];
    model.strSelected = @"P";

    //example reload table
    dispatch_async(dispatch_get_main_queue(), ^{
        [self.tblView reloadData];
    });



}

}
-(void)btnNA:(UIButton *)sender

You can either have a model or a mutable dictionary to represent selection of your buttons.

NSMutableDictionary *buttonSelection = [@{@"P_Button" : @"Selected",
                                          @"F_Button" : @"Selected",
                                          @"W_Button" : @"Selected",
                                          @"NA_Button" : @"Selected"} mutableCopy];

Inside your method cellForRowAtIndexPath . You can simply use this dictionary for each cell to update:

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

        static NSString *STI=@"STI";

        AuditTableViewCell *cell = (AuditTableViewCell *)[tableView dequeueReusableHeaderFooterViewWithIdentifier:STI];

        if (cell == nil)
        {
            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AuditTableViewCell" owner:self options:nil];
            cell = [nib objectAtIndex:0];
            cell.accessoryType=UITableViewCellAccessoryNone;
        }

        if ([[buttonSelection objectForKey:@"P_Button"] isEqualToString:@"Selected"]) {
            [cell.passbtn setSelected:YES];
        }

        return cell;
}

Apart from this, it's better to have use delegate pattern for your custom cell to get the functionality you want. It can be done in the following way.

@protocol CustomCellProtocol <NSObject>

- (void)passButtonSelected:(BOOL)selected forIndexPath:(NSIndexPath *)indexPath;

@end

@interface CustomTableViewCell : UITableViewCell

@property (nonatomic, weak) id<CustomCellProtocol> cellDelegate;

@property (nonatomic) NSIndexPath *indexPath;

@end

In your @implementation or .m file of CustomCell, on click of button, do the following

- (void)passButtonSelected {

    [self.cellDelegate passButtonSelected:YES forIndexPath:self.indexPath];
}

Inside you cellForRowAtIndexPath method,

- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

        static NSString *STI=@"STI";

        AuditTableViewCell *cell = (AuditTableViewCell *)[tableView dequeueReusableHeaderFooterViewWithIdentifier:STI];

        if (cell == nil)
        {
            NSArray *nib = [[NSBundle mainBundle] loadNibNamed:@"AuditTableViewCell" owner:self options:nil];
            cell = [nib objectAtIndex:0];
            cell.accessoryType=UITableViewCellAccessoryNone;
        }

        cell.indexPath = indexPath;
        cell.cellDelegate = self;            

        if ([[buttonSelection objectForKey:@"P_Button"] isEqualToString:@"Selected"]) {
            [cell.passbtn setSelected:YES];
        }

        return cell;
}

So, when you click button on your cell. You will get the following call in your tableview.m file.

- (void)passButtonSelected:(BOOL)selected forIndexPath:(NSIndexPath *)indexPath {

    NSMutableDictionary *statusDic = [[self.buttonStatusModelArray objectAtIndex:indexPath.row] mutableCopy];
   [statusDic setObject:(selected ? @"Selected" : @"NonSelected") forKey:@"P_Button"];

    [self.buttonStatusModelArray replaceObjectAtIndex:indexPath.row withObject:statusDic];
}

If you have any problems in implementing this, please let me know. Feel free to suggest edits to make this better :)
