For practice i am doing show/hide the value in UITableView like MXPlayer in android.
when i add the value, it should show NEW in lable i have made for custom cell. Once i read the value, it will display in next view, then coming back to list view its shows correct as i excepted, but if i click another value, it will change the previous value.
this code i have tried so far..help me
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *Identifier = #"ceelll";
customCell *cell =(customCell *) [tableView dequeueReusableCellWithIdentifier:Identifier];
if (cell==nil) {
cell=[[[NSBundle mainBundle]loadNibNamed:#"customCell" owner:self options:nil]objectAtIndex:0];
}
cell.dataLbl.text=self.listData[indexPath.row];
if([self.checkedData isEqual:indexPath])
{
cell.NewHideLbl.text=#"VIEW";
cell.NewHideLbl.textColor=[UIColor greenColor];
}
else
{
cell.NewHideLbl.text=#"NEW";
cell.NewHideLbl.textColor=[UIColor redColor];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if(self.checkedData)
{
customCell* cell =(customCell*) [tableView cellForRowAtIndexPath:self.checkedData];
cell.NewHideLbl.text=#"NEW";
cell.NewHideLbl.textColor=[UIColor redColor];
}
if([self.checkedData isEqual:indexPath])
{
self.checkedData = nil;
}
else
{
customCell* cell =(customCell*) [tableView
cellForRowAtIndexPath:indexPath];
cell.NewHideLbl.text=#"VIEW";
cell.NewHideLbl.textColor=[UIColor greenColor];
self.checkedData = indexPath;
}
self.detailObj.tempStr=self.listData[indexPath.row];
[self.navigationController pushViewController:self.detailObj animated:YES];
}
this is for learning purpose only..Help me thanks in advance..
simple mistake again you given same name so its comming wrong so you need to change NEW to VIEW
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if(self.checkedData)
{
customCell* cell =(customCell*) [tableView cellForRowAtIndexPath:self.checkedData];
// cell.NewHideLbl.text=#"NEW"; here again you are assigning label NEW so its getting new one
cell.NewHideLbl.text=#"VIEW";
cell.NewHideLbl.textColor=[UIColor greenColor];
}
if([self.checkedData isEqual:indexPath])
{
self.checkedData = nil;
}
else
{
customCell* cell =(customCell*) [tableView
cellForRowAtIndexPath:indexPath];
cell.NewHideLbl.text=#"VIEW";
cell.NewHideLbl.textColor=[UIColor greenColor];
self.checkedData = indexPath;
}
self.detailObj.tempStr=self.listData[indexPath.row];
[self.navigationController pushViewController:self.detailObj animated:YES];
}

I have a question about UITAbleViewCell's.
I have implemented UITableViewDelegate method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self tableView:tableView cellForRowAtIndexPath:indexPath];
cell.backgroundColor = [UIColor redColor];
cell.textLabel.textColor = [UIColor redColor];
cell.textLabel.text = #"Title";
}
After I click on desired cell, nothing happens...
Why it doesn't work as I expected? Also, what should I do to make it work?
You have to create some base model for cell states e.g:
#property NSString *modelState = #"red"; // this is fast hint, but it can be a enum with states.
all cell will have one title after tap.
... other controller code...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [self.restaurantTable dequeueReusableCellWithIdentifier:#"cell_ID"];
// cell customization method
[self customizeCell:cell accordingToStateStr:modelState];
return cell;
}
... other controller code...
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:NO];
// Set other state for cell
self.modelState = #"red";
[tableView reloadData];
}
- (void)customizeCell:(UITableViewCell*)cell accordingToStateStr:(NSString *)str {
if ([str isEqualToString:#"red"]) {
cell.backgroundColor = [UIColor redColor];
cell.textLabel.textColor = [UIColor redColor];
cell.textLabel.text = #"Title";
} else if(...) {
//Other options..
}
}
[tableView reloadData]; - will trigger once again "cellForRow" method and your table will be redrawn according to new model.
You can use for cell states emuns instead NSString object (this is only scaffold for you).
Try this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
// config the selected cell
....
}
You should ask the UITableView for the cell directly rather than ask its delegate (self in your code). Cause its delegate may dequeue or create a fresh cell rather than giving you the cell seleceted.
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;
}
}
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.
I have two UITableViewCell class and I want to load this two UITableViewCell in my UITableView.
I know that when I want to load one UITableViewCell without xib file in my UITableView I use this code :
- (void)viewDidLoad
{
[super viewDidLoad];
[table registerClass:[SecondViewCell class] forCellReuseIdentifier:CellIdentifier];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
if(indexPath.row == 0){
SecondViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.backgroundColor = [UIColor blueColor];
cell.Email.text = [NSString stringWithFormat:#"sdasdd#gmail.com"];
cell.Address.text = txt;
return cell;
}
else{
//load second cell
}
}
now I want to how to load two UITableViewCell in my UITableView
- (void)viewDidLoad
{
[super viewDidLoad];
[table registerClass:[FirstViewCell class] forCellReuseIdentifier:CellIdentifier];
[table registerClass:[SecondViewCell class] forCellReuseIdentifier:CellIdentifier2];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
if(indexPath.row == 0){
SecondViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2 forIndexPath:indexPath];
cell.backgroundColor = [UIColor blueColor];
cell.Email.text = [NSString stringWithFormat:#"sdasdd#gmail.com"];
cell.Address.text = txt;
return cell;
}
else{
FirstViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.backgroundColor = [UIColor greenColor];
return cell;
}
return nil;
}
I tried to hide my detailTextLabel.cell while my tableview loads,by the code,
cell.textLabel.text=[array objectAtIndex:indexPath.row];
cell.detailTextLabel.text=[detailarray objectAtIndex:indexPath.row];
cell.detailTextLabel.hidden = YES;
While selecting the row, try to display the detailarray in didSelectRowAtIndexPath, as expected the detailarray is displaying while am pressing the row and once i stop pressing it, the detailarray text disappears, why it is happening so,
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSLog(#"indexpath is %d", indexPath.row);
selectedIndex = indexPath.row;
isSearching = YES;
[self.tableview beginUpdates];
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text=[dealarray objectAtIndex:indexPath.row];
cell.detailTextLabel.text=[detailarray objectAtIndex:indexPath.row];
cell.detailTextLabel.hidden = NO;
[self.tableview endUpdates];
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if (isSearching && indexPath.row == selectedIndex)
{
return 77;
}
return 44;
}
EDITED:
Assigned a variable 'a' in .h file and used the code as follows,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
// Configure the cell...
cell.textLabel.text=[dealarray objectAtIndex:indexPath.row];
cell.detailTextLabel.text=[detailarray objectAtIndex:indexPath.row];
NSLog(#"dealarray %#\n %#",dealarray,detailarray);
if (a==-1) {
cell.detailTextLabel.hidden = YES;
}
else if(a==indexPath.row)
{
cell.detailTextLabel.hidden = NO;
}
else cell.detailTextLabel.hidden = YES;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
NSLog(#"indexpath is %d", indexPath.row);
selectedIndex = indexPath.row;
isSearching = YES;
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
cell.textLabel.text=[dealarray objectAtIndex:indexPath.row];
cell.detailTextLabel.text=[detailarray objectAtIndex:indexPath.row];
a=indexPath.row;
[tableview reloadData];
}
For this, You can use two type of cell.
For normal data, use basic cell. On selection, reload table or cell and use another detailLabel cell for selected row only.
And it will solve your issue.
Thanks
If i understood your requirement, Can you try below code to resolve your purpose.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath {
/* .
Write necessary code here....
*/
// -------------
cell.textLabel.text=[array objectAtIndex:indexPath.row];
if (![selectedRowIndexs containsObject:[NSNumber numberWithInt:indexPath.row]])
{
cell.detailTextLabel.hidden = YES;
}
else
{
cell.detailTextLabel.hidden = NO;
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
cell.detailTextLabel.text=[detailarray objectAtIndex:indexPath.row];
cell.detailTextLabel.hidden = NO;
if (![selectedRowIndexs containsObject:[NSNumber numberWithInt:indexPath.row]])
{
[selectedRowIndexs addObject:[NSNumber numberWithInt:indexPath.row]];
}
}
