I hope this clears your doubt.
I want to checkmark the data when the data is being loaded in the uitablecell. I know it works when you put it in the didselect section but can we use it in the cellForRowAtIndexPath. If yes how to use it? I have tried but it doesn't show any checkmarks.

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

And lastIndexPath is a property(retain) NSIndexPath* lastIndexPath;
Why the UITableViewCells don't reload the checkmarks after selecting, scrolling away, then scrolling back?

You missed out the ! (inverse operator) on the following line meaning that the state will always be the same.
[stateArray replaceObjectAtIndex:indexPath.row withObject:[NSNumber numberWithBool:[[stateArray objectAtIndex:indexPath.row] boolValue]]];
It should be
[stateArray replaceObjectAtIndex:indexPath.row withObject:[NSNumber numberWithBool:![[stateArray objectAtIndex:indexPath.row] boolValue]]];
Edit --- I've refactored both methods because it can be done with a lot less code and it will completely simplify the methods for you.

I suggest a more object oriented approach. This will ensure that your code is flexible and displays correctly all the time.
For each item you wish to display in your table, have a corresponding object. You mentioned that you are displaying contacts, so let's suppose your object is called "Contact":
//Contact.h
#interface Contact : NSObject
#property BOOL selected;
#property NSString *name;
#end
//Contact.m
#import Contact.h
#implementation Contact
+ (id) contactWithName:(NSString*)name {
Contact *nContact = [Contact new];
nContact.name = name;
nContact.selected = NO;
return nContact;
}
#end
Then, just make your view work something like this:
//ContactView.m
#interface ContactView()
#property NSMutableArray *contacts;
#end
#implementation ContactView
#synthesize contacts;
- (void) viewDidLoad {
[super viewDidLoad];
//get your contact list here. When creating contacts, be sure to assign their selected and their name as you require.
contacts = #[[Contact contactWithName:#"John"], [Contact contactWithName:#"Jane"]];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *cellID = #"inviteCell";
UITableViewCell *cell = [tableview dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
Contact *cellContact = [contacts objectAtIndex:indexPath.row];
cell.textLabel.text = cellContact.name;
cell.accessoryType = cellContact.selected == YES ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
Contact *cellContact = [contacts objectAtIndex:indexPath.row];
cellContact.selected = !cellContact.selected;
[contacts replaceObjectAtIndex:indexPath.row withObject:cellContact];
[tableView reloadData]; //to refresh without animation
//[tableView reloadSections:[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(0, [tableView numberOfSections])] withRowAnimation:UITableViewRowAnimationTop]; //to refresh with animation
}
#end
And boom, easy to use tables that always look right, queue properly, and are object oriented for easy maintenance later.
The cell selection problem was not solved, even when insertObject was replaced with replaceWithObject, however, one should not waste time setting BOOL objects with an NSInteger inside an NSMutableArray. Instead, for cell selection memory, one should use NSDictionary like this:
#property (nonatomic, strong) NSMutableDictionary * selectedRowCollection;
- (void)viewDidLoad{
self.selectedRowCollection = [[NSMutableDictionary alloc] init];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath;
{
id object = contactsObjects[indexPath.row];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (cell.accessoryType == UITableViewCellAccessoryNone)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[self.selectedRowCollection setObject:#"1" forKey:[NSString stringWithFormat:#"%d",indexPath.row]];
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
[self.selectedRowCollection removeObjectForKey:[NSString stringWithFormat:#"%d",indexPath.row]];
}
//slow-motion selection animation.
[tableView deselectRowAtIndexPath:indexPath animated:YES];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
BOOL showCheckmark = [[self.selectedRowCollection valueForKey:[NSString stringWithFormat:#"%d",indexPath.row]] boolValue];
if (showCheckmark == YES)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
}
You are not doing this UITableViewCell *cell = [tableview dequeueReusableCellWithIdentifier:cellID];
if (cell == nil) {cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellID];
}
Allocating is necessary if cell is nil. Or it cause problem while scrolling.
Plz anyone tell me how i select the row at one time with checkmark while other row are not checkmark.I tried but in my case there is mutiple row selected with checkmark. Basically I want to save one row with checkmark when i select another row then previous row deselect and this row select with checkmark. Here is my Code
- (NSString *)getKeyForIndex:(int)index
{
return [NSString stringWithFormat:#"KEY%d",index];
}
- (BOOL) getCheckedForIndex:(int)index
{
if([[[NSUserDefaults standardUserDefaults] valueForKey:[self getKeyForIndex:index]]boolValue]==YES)
{
return YES;
}
else
{
return NO;
} }
- (void) checkedCellAtIndex:(int)index
{ BOOL boolChecked = [self getCheckedForIndex:index];
[[NSUserDefaults standardUserDefaults] setValue:[NSNumber numberWithBool:!boolChecked] forKey:[self getKeyForIndex:index]];
[[NSUserDefaults standardUserDefaults] synchronize];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return List.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *subviewCells = #"Cells";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:subviewCells];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:subviewCells];
}
cell.textLabel.text = [List objectAtIndex:indexPath.row];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[self checkedCellAtIndex:indexPath.row];
if([self getCheckedForIndex:indexPath.row]==YES)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
selectLanguage = [List objectAtIndex:indexPath.row];
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
[self checkedCellAtIndex:indexPath.row];
if([self getCheckedForIndex:indexPath.row]==NO)
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
else
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
selectLanguage = [List objectAtIndex:indexPath.row];
}
#end;
Try this :
Single Row Selection:
create a new variable to track the index In Controller:
int selectedIndex;
in UITableView cellForRowAtIndexPath method:
if(indexPath.row == selectedIndex)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
and in UITableView didSelectRowAtIndex method:
selectedIndex = indexPath.row;
[tableView reloadData];
2 way as per you want:
.h file:
NSIndexPath* checkedIndexPath;
#property (nonatomic, retain) NSIndexPath* checkedIndexPath;
.m file:
#synthesize checkedIndexPath;
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
//do you stuff here
if([self.checkedIndexPath isEqual:indexPath])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//do work for checkmark
if(self.checkedIndexPath)
{
UITableViewCell* uncheckCell = [tableView
cellForRowAtIndexPath:self.checkedIndexPath];
uncheckCell.accessoryType = UITableViewCellAccessoryNone;
}
if([self.checkedIndexPath isEqual:indexPath])
{
self.checkedIndexPath = nil;
}
else
{
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryCheckmark;
self.checkedIndexPath = indexPath;
}
}
Happy coding!!
I have a Uitableview which has Accessory type set as "CheckMark" if the cell is selected (Checked) I want to add the contents of the cell to an array and if it is unchecked I want to remove the same from the array.
I have added this code in tableView:didSelectRowAtIndexPath::
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell * cell = [tableView cellForRowAtIndexPath:indexPath];
NSIndexPath *tableSelection = [listingSet indexPathForSelectedRow];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
cell.accessoryType = UITableViewCellAccessoryNone;
[listingSet deselectRowAtIndexPath:tableSelection animated:YES];
}
else {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
ID = [NSString stringWithFormat:#"%#",[[ParsedData valueForKey:#"ID"]objectAtIndex:indexPath.row]];
NSLog(#"++++++IDSSS %#",ID);
NSString *titlename = [NSString stringWithFormat:#"%#.%#",[[ParsedData valueForKey:#"UserFileName"]objectAtIndex:indexPath.row],[[ParsedData valueForKey:#"fileExtension"]objectAtIndex:indexPath.row]];
[Selectedfiles addObject:ID];
[Selectedfiles retain];
NSLog(#"++++++Titlesss %#",Selectedfiles);
[listingSet deselectRowAtIndexPath:tableSelection animated:YES];
}
}
In tableView:didSelectRowAtIndexPath::
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell * cell = [tableView cellForRowAtIndexPath:indexPath];
NSIndexPath *tableSelection = [listingSet indexPathForSelectedRow];
ID = [NSString stringWithFormat:#"%#",[[ParsedData valueForKey:#"ID"]objectAtIndex:indexPath.row]];
if (cell.accessoryType == UITableViewCellAccessoryCheckmark) {
// Remove id
[Selectedfiles removeObject:ID];
cell.accessoryType = UITableViewCellAccessoryNone;
[listingSet deselectRowAtIndexPath:tableSelection animated:YES];
}
else {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
// Add id
[Selectedfiles addObject:ID];
NSLog(#"++++++IDSSS %#",ID);
NSString *titlename = [NSString stringWithFormat:#"%#.%#",[[ParsedData valueForKey:#"UserFileName"]objectAtIndex:indexPath.row],[[ParsedData valueForKey:#"fileExtension"]objectAtIndex:indexPath.row]];
NSLog(#"++++++Titlesss %#",Selectedfiles);
[listingSet deselectRowAtIndexPath:tableSelection animated:YES];
}
}
