How to get values of tableview cells having multiple selections? - ios

Question

I have a tableview in which i have provided checkmarks as a accessory to multiple cells.
Now I want to get values of all those cells having checkmarks.
#import "HealthIssues.h"
#interface HealthIssues ()<UITableViewDataSource,UITableViewDelegate>
{
NSIndexPath* checkedIndexPath;
}
#property (nonatomic, retain) NSIndexPath* checkedIndexPath;
#end
#implementation HealthIssues
#synthesize HealthIssuesTV;
#synthesize checkedIndexPath;
- (void)viewDidLoad {
[super viewDidLoad];
PickerList=[[NSArray alloc]initWithObjects:#"None" ,#"Diabetes", #"Heart Problem" , #"Thyroid" , #"Over Weight" , #"Kidney Issues" , #"Lever Issues" , #"Vitamins Deficiency" , #"Blood Pressure" , nil];
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [PickerList count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell==Nil) {
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:cellIdentifier];
}
if (indexPath.row == 0){
if ([self.checkedIndexPath isEqual:indexPath])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
}
cell.textLabel.text = [PickerList objectAtIndex:indexPath.row];
cell.tintColor=[UIColor blueColor];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
{
int z=0;
if (indexPath.row==0)
{
NSArray *visibleCells = [tableView visibleCells];
for (UITableViewCell *cell in visibleCells)
{
if (z==0)
{
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
z++;
}
else
{
[cell setAccessoryType:UITableViewCellAccessoryNone];
z++;
}
}
}
else
{
if ([selectedCell accessoryType] == UITableViewCellAccessoryNone)
{
[selectedCell setAccessoryType:UITableViewCellAccessoryCheckmark];
}
else
{
[selectedCell setAccessoryType:UITableViewCellAccessoryNone];
}
[tableView reloadData];
}
}
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
#end
This Works perfect for me as per my requirements. now i want to store selected rows in dictionary.

Answer 1

#interface selectUsers ()
{
NSMutableArray *selected_ids;
}
- (void)viewDidLoad {
[super viewDidLoad];
selected_ids = [[NSMutableArray alloc]init];
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSString *_id = [[yourarray objectAtIndex:indexPath.row]valueForKey:#"_id"];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
[selected_ids removeObject:_id];
cell.accessoryType = UITableViewCellAccessoryNone;
} else {
[selected_ids addObject:_id];
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
}
Use selected_ids array where you want.

Answer 2

Try to get values from your data source of array and get all selected rows of UITableView:
Following code will give you all indexpaths of selected rows:
NSArray *arrIndexpaths = [YourTableView indexPathsForSelectedRows]; // Returns indexpaths for multiple selection in Table view.
Then Get value from the array by indexpath.row and indexpath.section whatever you used during in data source method.

Answer 3

First of all, you should do:
tableView.allowsMultipleSelection = YES;
Then you can get list of selected rows by:
NSArray *selectedIndexPaths = [self.tableView indexPathsForSelectedRows];
As you have now list of selected rows, you can get row or data of row.

Answer 4

You can use array for this.
- (void)viewDidLoad
{
arrData=[[NSMutableArray alloc]init];
}
On didSelectRowAtIndexPath add your value into array.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[arrData addObject:[YourDataArray objectAtIndex:indexPath.row]];
}
May be it will help you.

Answer 5

try this..
NSMutableArray *selectedIndexes ; // instance variable, do initialization in viewDidLoad
i am assuming that you are using didSelectRowAtIndexPath for selecting cell (i mean not a custom button action)
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath: (NSIndexPath *)indexPath
{
if ([selectedIndexes containsObject:indexPath])
{
[selectedIndexes removeObject:indexPath];
}
else
{
[selectedIndexes addObject:indexPath];
}
}
Now you can get all selected cells using index values in selectedIndexes array
for ex UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:1];
edit :
remove all objects from selectedIndexes after selection process is over

Answer 6

#interface RestTableViewController ()<UISearchBarDelegate>{
NSMutableSet *setTemp;
// NSMutableArray *setTemp;
}
In ViewDidLoad
- (void)viewDidLoad {
[super viewDidLoad];
setTemp = [[NSMutableSet alloc] initWithCapacity:1];
. . .
}
In cellForRowAtIndexPath
cell.selectionStyle = UITableViewCellSelectionStyleNone;
[self markCell:cell atIndex:indexPath.row];
Create a Method
- (void)markCell:(UITableViewCell *)cell atIndex:(NSInteger)index{
if ([setTemp containsObject:[NSNumber numberWithInteger:index]]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
}
In didSelectRowAtIndexPath
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
{
// Restaurent is my Object File
Restaurent *obj = [restMutableArray objectAtIndex:indexPath.row];
if ([setTemp containsObject:[NSNumber numberWithInteger:indexPath.row]]) {
[setTemp removeObject:[NSNumber numberWithInteger:indexPath.row]];
// tempMainArray is an array which manages the title of selected or deselected Rows . . .
[tempMainArray removeObject:obj.strTitle];
NSLog(#"Selected Row Data %#",tempMainArray);
}
else {
[setTemp addObject:[NSNumber numberWithInteger:indexPath.row]];
[tempMainArray addObject:obj.strTitle];
NSLog(#"Selected Row Data %#",tempMainArray);
}
[self markCell:cell atIndex:indexPath.row];
}
To Select All The Cell
#pragma mark : Select All Data Method. . .
- (IBAction)actionBtnClicked:(id)sender {
{
[setTemp removeAllObjects];
for (int i = 0 ; i < [restMutableArray count]; i++) {
Restaurent *obj = [restMutableArray objectAtIndex:i];
[tempMainArray addObject:obj.strTitle];
[setTemp addObject:#(i)];
}
NSLog(#"%#",tempMainArray);
[self.tableView reloadData];
}
