How To Get TableviewCell Selected Check Mark Row Values Using Objective C? - ios

I need to create tableviewcell checkmark selected row title label and detail label values get after clicking the submit button.
- (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] autorelease];
}
if ([indexPath compare:self.lastIndexPath] == NSOrderedSame)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
// UITableView Delegate Method
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"Section:%ld Row:%ld selected and its data is %# %#",(long)indexPath.section,(long)indexPath.row,cell.sector_Label.text,cell.textLabel.text);
selectedIndex = indexPath.row;
[tableView reloadData];
}
- (IBAction)Submit_Click:(id)sender {
// Here I need to get tableview cell check mark selected cell label values.
}

Check this:
-(IBAction)Submit_Click:(id)sender {
// Here I need to get tableview cell check mark selected cell label values.
if (selectedIndex >= 0) {
NSIndexPath* indexPath = [NSIndexPath indexPathForRow:selectedIndex inSection:0];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"detailTextLabel: %#", cell.detailTextLabel.text);
NSLog(#"title: %#", cell.textLabel.text);
}
}

You can use indexPathsForSelectedRows
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
cell = [tableView cellForRowAtIndexPath:indexPath];
if(cell.isSelected)
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
else
{
[cell setSelected:YES animated:YES]
}
}
-(IBAction)Submit_Click:(id)sender {
// Here I need to get tableview cell check mark selected cell label values.
NSArray *indexes = [self.tableview indexPathsForSelectedRows];
if (indexes.count > 0)
{
//do your stuff as you get selected row index array
}
}

Obj-C - Deselect the selected cell when another cell is tapped?

I'm currently using the below code for didSelectRowAtIndexPath. With the way I have my code written now, if a user taps a cell a green checkmark appears. If they tap the same cell again, the green checkmark disappears. That said, I want to make it so that if the user taps a different cell after making a selection, the green checkmark should disappear from the previously selected cell. How can I accomplish this?
ViewController.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if(_selectedRowIndex && indexPath.row == _selectedRowIndex.row) {
ClientTableViewCell *cell2 = [tableView cellForRowAtIndexPath:indexPath];
cell2.greenCheck.image = [UIImage imageNamed:#""];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
_selectedRowIndex = nil;
}
else { self.selectedRowIndex = indexPath;
ClientTableViewCell *cell2 = [tableView cellForRowAtIndexPath:indexPath];
NSDictionary *client = self.sectionClients[indexPath.section][indexPath.row];
cell2.greenCheck.image = [UIImage imageNamed:#"added.png"];
NSLog(#"SELECTED");
}
[tableView beginUpdates];
[tableView endUpdates];
}
You can store the last selected indexpath, when a new cell is selected, you get the previous cell with the stored indexpath and deselect it.
#implementation ViewController
NSIndexPath *lastIndexPath;
...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if (lastIndexPath != nil){
UITableViewCell *oldCell = [self.tableView cellForRowAtIndexPath:lastIndexPath];
oldCell.accessoryType = UITableViewCellAccessoryNone;
}
if(lastIndexPath != indexPath) {
lastIndexPath = indexPath;
UITableViewCell *cell2 = [tableView cellForRowAtIndexPath:indexPath];
cell2.accessoryType = UITableViewCellAccessoryCheckmark;
}else{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
lastIndexPath = nil;
}
[tableView beginUpdates];
[tableView endUpdates];
}

How to append custom tableviewcells to tableview one by one

I have two tableview controllers lets say PopoverElementsListTable ,ElementsViewTable. one tableview will be in popover state when I click on one of the PopoverElementsListTable cell a custom cell has to added to the ElementsViewTable.I'm able to append only one cell when I try to add another cell to ElementsViewTable its getting replaced with previous cell.
#pragma mark - TableView delegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:
(NSInteger)section{
if (tableView == PopoverElementsListTable) {
return [myArray count];
}
else if (tableView == ElementsViewTable) {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath{
if (tableView == PopoverElementsListTable) {
static NSString *cellId = #"autoaddress";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
cellId];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:
UITableViewCellStyleDefault reuseIdentifier:cellId];
}
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}else {
NSLog(#"_selectedIndex %lu",(unsigned long)_selectedIndex);
if(_selectedIndex == 1){
AutoFillAddressFormElementcell * cell = [tableView dequeueReusableCellWithIdentifier:#"autoAddressCell"];
if (!cell) {
cell = [[AutoFillAddressFormElementcell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"autoAddressCell"];
}
return cell;
}else if(_selectedIndex == 2){
NSLog(#"Test # 123");
AddressSetterFormElementCell * cell = [tableView dequeueReusableCellWithIdentifier:#"setAddressCell"];
if (!cell) {
cell = [[AddressSetterFormElementCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"setAddressCell"];
}
return cell;
}else{
static NSString *cellId = #"autoaddress";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:
UITableViewCellStyleDefault reuseIdentifier:cellId];
}
cell.textLabel.text = #"List";
return cell;
}
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath{
if(tableView == PopoverElementsListTable){
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"Section:%ld Row:%ld selected and its data is %#",
(long)indexPath.section,(long)indexPath.row,cell.textLabel.text);
[_transarentView setHidden:true];
_selectedIndex = indexPath.row + 1;
NSLog(#"number %lu",(unsigned long)_selectedIndex);
[_displayFromElementTableView reloadData];
}
if(tableView == ElementsViewTable){
}
}
I know I'm able to append only one item because of return 1 in numberOfRowsInSection delegate. I tried replacing with another number but what I achieved is all the cells are identical.How can I get the dynamic count here? How to append customcells one by one which are unidentical.
You need to do it by identifying indexpath .
if (indexPath.row == 0) {
Customcell1 *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
}else if (indexPath.row == 1){
Customcell2 *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
}
return cell;
and so on....
You can check the table view too if you want.

IOS: UITableView have to double click to deselect

I have a UITableView that holds a tableView that populates 'prototype cells' from a mutable array and whose cells show an 'accessory checkmark' when you select them. I have a textfield in a view below the tableview and whose data I am then appending to the array that is populating the tableview. My problem is that after I append the new data which adds a cell to the tableview I have to touch a cell twice in order to deselect any of the cells I previously selected.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"skillName" forIndexPath:indexPath];
cell.textLabel.text = skillsOptions[indexPath.row];
// Configure the cell...
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *tableViewCell = [tableView cellForRowAtIndexPath:indexPath];
//tableViewCell.accessoryView.hidden = NO;
tableViewCell.accessoryType = UITableViewCellAccessoryCheckmark;
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *tableViewCell = [tableView cellForRowAtIndexPath:indexPath];
//tableViewCell.accessoryView.hidden = YES;
tableViewCell.accessoryType = UITableViewCellAccessoryNone;
[skillsList removeObject:skillsOptions[indexPath.row]];
}
-(void)grabSelectedSkills {
for (NSIndexPath *indexPath in self.tableView.indexPathsForSelectedRows) {
NSString *skill = skillsOptions[indexPath.row];
//NSString *skill = [NSString stringWithFormat:#"%li",(long)indexPath.row];
[skillsList addObject:skill];
}
NSLog(#"skillsList: %#",skillsList);
}
- (IBAction)continue:(id)sender {
[self grabSelectedSkills];
}
- (IBAction)addOtherSkills:(id)sender {
if (self.otherSkill.text.length > 1) {
[skillsOptions addObject:self.otherSkill.text];
self.otherSkill.text = #"";
[self.tableView endEditing:YES];
[self.tableView reloadData];
}
You need to track your selection/deselection status outside of the cell - a dictionary keyed by the "skill option" is probably a good choice.
You can then use this in cellForRowAtIndexPath and didSelectRowAtIndexPath to add/remove the check mark as required. You should deselect the row in didSelectRowAtIndexPath and get rid of didDeselectRowAtIndexPath -
Create self.selectedCells as an NSMutableDictionary property.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"skillName" forIndexPath:indexPath];
// Configure the cell...
NSString *skillOption=skillsOptions[indexPath.row];
cell.textLabel.text = skillOption;
if (self.selectedCells[skillOption]!= nil) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *tableViewCell = [tableView cellForRowAtIndexPath:indexPath];
NSString *skillOption=skillsOptions[indexPath.row];
if (self.selectedCells[skillOption]!= nil) {
tableViewCell.accessoryType = UITableViewCellAccessoryNone;
[self.selectedCells removeObjectForKey:skillOption];
} else {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
self.selectedCells[skillOption]=skillOption;
}
[tableview deselectRowAtIndexPath:indexPath];
}
I think you should only use didSelectRowAtIndexPath: method (drop the didDeselectRowAtIndexPath: method) and check to select the cell if it's not and vice versa as-
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
BOOL cellSelected = NO;
// set cellSelected based on your condition
if(cellSelected)
{
// code to deselect the cell
}
else
{
// code to select the cell
UITableViewCell *tableViewCell = [tableView cellForRowAtIndexPath:indexPath];
//tableViewCell.accessoryView.hidden = NO;
tableViewCell.accessoryType = UITableViewCellAccessoryCheckmark;
}
}

Hide or move seleted Cell and load a new custom Cell in that indexPath.row in UItableView

I have a UITableView call myTableView with two custom UITableViewCell call TableViewCell & ExTableViewCell. What I want is, when user tap on a cell, the existing cell TableViewCell will hide/move and ExTableViewCell is loaded in that indexpath.row and when tap on that indexpath.row again it hide ExTableViewCell and bring back the old TableViewCell in that position.
Here is my code:
- (void)viewDidLoad
{
[super viewDidLoad];
self.myArray = [[NSArray alloc] initWithObjects:#"one", #"two", #"three", #"four", #"five", #"six", nil];
selectedIndex = -1;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (selectedIndex == indexPath.row)
{
return 230;
}
else
{
return 40;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.myArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
TableViewCell *Cell = (TableViewCell *)[self.myTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!Cell)
{
Cell = [[TableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Cell.myLabel.text = [self.myArray objectAtIndex:indexPath.row];
if (selectedIndex == indexPath.row)
{
static NSString *CellIdentifier = #"CellEx";
ExTableViewCell *Cell = (ExTableViewCell *)[self.myTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!Cell)
{
Cell = [[ExTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Cell.backgroundColor = [UIColor redColor];
Cell.exLabel.text = [self.myArray objectAtIndex:indexPath.row];
}
else
{
// Do close cell stuff
//Cell.backgroundColor = [UIColor clearColor];
}
return Cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// Expand row when user taps row
if (selectedIndex == indexPath.row)
{
selectedIndex = -1;
[self.myTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation: UITableViewRowAnimationFade];
return;
}
// When user taps different row
if (selectedIndex != -1)
{
NSIndexPath *prevPath = [NSIndexPath indexPathForRow:selectedIndex inSection:0];
selectedIndex = indexPath.row;
[self.myTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:prevPath] withRowAnimation:UITableViewRowAnimationFade];
}
// When user taps new row with none expanded
selectedIndex = indexPath.row;
[self.myTableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
But for some reason in the ExTableViewCell label is not showing any text. And the ExTableViewCell is still top of it. How can I achieve this?
A lot a thanks for advance. Have a good day. :)
This is the out put:
My problem:
You don't need to 'hide' the old cell in order to show the new one, you just reload the proper content at the desired index path. Something like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
MyCustomCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
if ([self.selectedPath isEqual:indexPath]) {
//configure the extended cell
cell = [tableView dequeueReusableCellWithIdentifier:#"CellEx" forIndexPath:indexPath];
...
} else {
//configure the default cell
}
}
And here is how to handle the selected/deselected state:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSIndexPath *oldPath = [self.selectedPath copy];
self.selectedPath = indexPath;
NSArray *paths = #[indexPath];
if (oldPath && ![oldPath isEqual:indexPath]) {
paths = [paths arrayByAddingObject:oldPath];
} else if ([oldPath isEqual:indexPath]){
self.selectedPath = nil;
}
[self.tableView beginUpdates];
[self.tableView reloadRowsAtIndexPaths:paths withRowAnimation:UITableViewRowAnimationAutomatic];
[self.tableView endUpdates];
}

store selected cells textLabel text in an array

How do i store all selected cells text label text in a NSMutableArray?
How do i remove the correct cells text from the NSMutableArray when a cell is deselected?
What i have this far:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
static NSString *CellIdentifier = #"Cell";
PFTableViewCell *cell = (PFTableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[PFTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if ([self.allSelectedUsers containsObject:indexPath]) {
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
NSLog(#"Yeeees");
}else{
[cell setAccessoryType:UITableViewCellAccessoryNone];
}
// Configure the cell
cell.textLabel.text = object[#"username"];
return cell;
}
This is when i'm selecting a cell:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if ([self.allSelectedUsers containsObject:indexPath]) {
[self.allSelectedUsers removeObject:indexPath];
}
else{
[self.allSelectedUsers addObject:indexPath];
}
NSLog(#"%d", self.allSelectedUsers);
[tableView reloadData];
}
When i check the log it doesn't display anything about the cells text label.
As I can't see how you're getting object instance, I suggest you to get back cell and read the title again.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
// Lazy initialise array
if (!self.allSelectedUsers) {
self.allSelectedUsers = [NSMutableArray new];
}
// Take action
if ([self.allSelectedUsers containsObject:indexPath]) {
[self.allSelectedUsers removeObject:indexPath];
} else {
[self.allSelectedUsers addObject:indexPath];
}
[tableView reloadData];
// Logging all selected users
for (NSIndexPath *sIndexPath in self.allSelectedUsers) {
NSLog(#"%#", [tableView cellForRowAtIndexPath:sIndexPath].textLabel.text);
}
}
You are currently storing NSIndexPath objects, not NSString objects, so it's not exactly what your question is asking. With your PFTableViewController, you have access to the selector objectAtIndexPath:.
for (NSIndexPath *indexPath in self.allSelectedUsers) {
NSLog(#"%#", [self objectAtIndexPath:indexPath][#"username"]);
}
Note: You shouldn't be calling reloadData in your didSelectRowAtIndexPath: responder; change the accessory type for the cell instead.
[[tableView cellForRowAtIndexPath:indexPath] setAccessoryType:UITableViewCellAccessoryCheckmark];
You should also implement didDeselectRowAtIndexPath: to know when a user deselects a row.
