I have a UITableView. I use this code to resize the selected row:
-(void) viewWillAppear:(BOOL)animated {
....
[self.tableView registerNib:[UINib nibWithNibName:#"ICSceneDetailViewTableViewCell" bundle:[NSBundle mainBundle]] forCellReuseIdentifier:IC_CELL_SCENE_EDITOR_CELL];
...
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
-(int) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (tableView == nil)
return 0;
if (self.scenes != nil) {
return self.scenes.count;
}
return 0;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
ICSceneDetailViewTableViewCell *cell = (ICSceneDetailViewTableViewCell*)[tableView dequeueReusableCellWithIdentifier:IC_CELL_SCENE_EDITOR_CELL forIndexPath:indexPath];
if (cell == nil) {
cell = [[ICSceneDetailViewTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:IC_CELL_SCENE_EDITOR_CELL];
}
ICScene *scene = [self.scenes objectAtIndex:[indexPath row]];
[cell.titleTextField setText:scene.title];
return cell;
}
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.selectedRow = indexPath.row;
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationNone];
[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:NO];
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([indexPath row] == self.selectedRow) {
return 250;
}
if (IS_IPAD) {
return 80;
}
else {
return 40;
}
}
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleNone;
}
BUT, after selecting any row (name it A, and A become resized):
if I drag another row (name it B) then randomly other rows disappears (except A).
if I scroll tableview and back to drag on same row (B) then, again randomly, other(s) cell(s) disappear(s), but not always the same(s).
if I comment heightForRowAtIndexPath then drag behavior is normal, but row can't be resized :(
I already searched many similar answers (adjusting selectedBackgroundView on cell, backgroundView cell, drawRect on cell, etc) but no one solution/workaround works for this simple (i think) code.
Thanks in advance :)
Yeh, answering my own question.
I found an alternative to resize selected UITableViewCell without calling to reloadRowsAtIndexPaths.
Replacing reloadRowsAtIndexPaths with:
[self.tableView beginUpdates];
[self.tableView endUpdates];
refreshes visible rows without calling cellForRowAtIndexPath. Imho the problem where dequeuing cells on every row being reloaded.
The resulting code is:
-(void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.selectedRow = indexPath.row;
[self.tableView scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionTop animated:NO];
[self.tableView beginUpdates];
[self.tableView endUpdates];
}
So, automagically there isn't any disappearing row :)

This is a function of getting the index , when clicking a pie chart.
what i need to do is expand the corresponding row of table when pie is selected
}
#end
If i got your idea you need to select the row at index path
- (void)pieChart:(XYPieChart *)pieChart didSelectSliceAtIndex:(NSUInteger)index
{
// get indexPath with index
// remember if you have few sections then you will need to update inSection:0 value
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:index inSection:0];
[yourTableView selectRowAtIndexPath:indexPath
animated:NO
scrollPosition:UITableViewScrollPositionNone];
// This will also Highlighted the row. Then delegate
[yourTableView.delegate someTableView didSelectRowAtIndexPath:indexPath];
}
I have a custom UITableViewCell, and I it expands on selection. What I want to do is make the cells height go back to normal (44), if the cell that was selected was reselected. Here is my code:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([indexPath isEqual:self.selectedCell] && ![[tableView indexPathForSelectedRow] isEqual:indexPath]) {
return 100;
}
return 44;
}
The code works fine, but it seems to be ignoring the 2nd term in the if statement. Apparently I'm doing it wrong. Is there a way to fix it?
I don't know why you compare cell with indexPath.
[indexPath isEqual:self.selectedCell]
If you just want expand selected cell.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([[tableView indexPathForSelectedRow] isEqual:indexPath])
{
return 100;
}
return 44;
}
UITableViewDelegate has deselect method
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
You need reload cell in this delegate
[tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
You need to store that particular index path in array to indicate that it is expanded Lets say you had selected 5 row that store that row number in an array, and reload that row after selecting it
Here is small code snippet that can help you to achieve this
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if([_arrExpandedRows containsObject:indexPath.row]){
[_arrExpandedRows removeObject:indexPath.row];
}else{
// [_arrExpandedRows removeAllObjects]; // IF you only want to make it work for single row
[_arrExpandedRows addObject:indexPath.row];
}
[tableView reloadData];
}
And in your heightForRowAtIndexPath
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if([_arrExpandedRows containsObject:indexPath.row]){
{
return 100;
}
return 44;
}
So what will it do if your array contains object of expanded row it will make reduce its row height and back to 44 and if not it will make it back to 100.
And above code will also work for multiple rows to expand and collapse at same time.
I think what you want is unselect cell when tap on a selected cell.
Store selectedIndexPath and compare in delegate
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if ([selectedIndexPath isEqual:indexPath])
{
[tableView deselectRowAtIndexPath:indexPath animated:1];
}
else
{
selectedIndexPath = indexPath;
}
[tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
You can do something like this:
#interface ViewController () <UITableViewDataSource, UITableViewDelegate>
#property (nonatomic, strong) UITableView* tableView;
#property (nonatomic, strong) NSMutableArray* selectedIndexPaths;
#end
<...>
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell* cell = [self.tableView dequeueReusableCellWithIdentifier:CELL_ID];
cell.textLabel.text = [NSString stringWithFormat:#"%i", (int)indexPath.row];
return cell;
}
#pragma mark UITableViewDelegate
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
CGFloat height = 44.0;
if ([_selectedIndexPaths containsObject:indexPath])
{
height = 100;
}
return height;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{//store or remove selected indexPaths
if ([_selectedIndexPaths containsObject:indexPath])
{
[_selectedIndexPaths removeObject:indexPath];
}
else
{
[_selectedIndexPaths addObject:indexPath];
}
[self.tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
I'm seeing a weird effect when inserting/deleting a UITableViewCell in a UITableView with animation (UITableViewRowAnimationTop).
The animation glitch happens when the cell to insert is much bigger than the cell above.
This video shows the glitch in the simulator, yellow cell appears suddenly out of no where when it's supposed to slide from top.
Here is the Xcode project from the video.
Bellow is the cell insertion/animation code.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2 + self.thirdCellVisible;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
if (indexPath.row == 1)
{
if (self.thirdCellVisible)
{
self.thirdCellVisible = !self.thirdCellVisible;
[tableView deleteRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
}
else
{
self.thirdCellVisible = !self.thirdCellVisible;
[tableView insertRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
}
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == self.thirdCellIndexPath.row)
{
return 100.0f;
}
return 44.0f;
}
You will have to call
[tableView beginUpdates]
and
[tableView endUpdates]
before and after calling insert/delete methods as below :
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2 + self.thirdCellVisible;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
if (indexPath.row == 1)
{
if (self.thirdCellVisible)
{
self.thirdCellVisible = !self.thirdCellVisible;
[self.tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];
}
else
{
self.thirdCellVisible = !self.thirdCellVisible;
[self.tableView beginUpdates];
[tableView insertRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];
}
}
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == self.thirdCellIndexPath.row)
{
return 100.0f;
}
return 44.0f;
}
According to Apple here:
To animate a batch insertion, deletion, and reloading of rows and
sections, call the corresponding methods within an animation block
defined by successive calls to beginUpdates and endUpdates. If you
don’t call the insertion, deletion, and reloading methods within this
block, row and section indexes may be invalid. Calls to beginUpdates
and endUpdates can be nested; all indexes are treated as if there were
only the outer update block.
At the conclusion of a block—that is, after endUpdates returns—the
table view queries its data source and delegate as usual for row and
section data. Thus the collection objects backing the table view
should be updated to reflect the new or removed rows or sections.
You will have to call [tableView beginUpdates] and [tableView endUpdates] before and after calling insert/delete methods respectively.
An example is provided by Apple on the above link.
Note: If your array and table view items are out of sync, without the begin/end calls an exception will be thrown.
Suggestion: Try first withRowAnimation:UITableViewRowAnimationAutomatic
Here is the link of video of my working code: https://dl.dropboxusercontent.com/u/30316681/480.mov

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

UITableViewCell *cell = [tableView dequeueReusableHeaderFooterViewWithIdentifier:cellId];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellId];
}
NSString *cellTitle = [NSString stringWithFormat:#"Cell %ld", (long)indexPath.row];
cell.textLabel.text = cellTitle;
if(indexPath.row == 2)
cell.backgroundColor = [UIColor yellowColor];
else
cell.backgroundColor = [UIColor clearColor];
return cell;
}
#end
Use [tableView beginUpdates] and [tableView endUpdates] as follow
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:NO];
if (indexPath.row == 1)
{
if (self.thirdCellVisible)
{
self.thirdCellVisible = !self.thirdCellVisible;
[self.tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];
}
else
{
self.thirdCellVisible = !self.thirdCellVisible;
[self.tableView beginUpdates];
[tableView insertRowsAtIndexPaths:#[self.thirdCellIndexPath]
withRowAnimation:UITableViewRowAnimationTop];
[self.tableView endUpdates];
}
}
}
In my UIViewController, I have a table view whose cells show text. The datasource and delegate of the UITableView is my UIViewController. The text to be showed by the cells is stored in an NSMutableArray.
I am able to populate the cells with the text initially, but I also want to implement a functionality, when a user clicks on a specific row the cell gets removed and the table is reloaded.
Here's my code and it's details:
taskList is a NSMutableArray
png images are ones that i need to add in every cell
my table contains only one section
the last row of the table will always show "Create New Task" with a "+" sign as an image
as user adds other task (handled by a separate controller), the taask gets added to the current table.The task will have a "-" sign image.
When user clicks on such a row, it will get deleted from the table
UIViewController's code:
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view from its nib.
taskList = [[NSMutableArray alloc] init];
addNewTask = [[AddTaskViewController alloc] init];
[taskList addObject:#"Create New Task"];
[taskList addObject:#"aaaaa"];
[taskList addObject:#"bbbbb"];
[taskList addObject:#"ccccc"];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
indexNumberInTaskList = [taskList count] - 1;
return [taskList count];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
cell = [tableView dequeueReusableCellWithIdentifier:#"myCell"];
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"myCell"];
}
if(indexNumberInTaskList >= 0)
{
cell.textLabel.text = [taskList objectAtIndex:indexNumberInTaskList];
if(indexPath.row == ([taskList count] - 1))
{
cell.imageView.image = [UIImage imageNamed:#"add.png"];
}
else
{
cell.imageView.image = [UIImage imageNamed:#"remove.png"];
}
indexNumberInTaskList = indexNumberInTaskList - 1;
}
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
int selectedRow = indexPath.row;
if(selectedRow == ([taskList count]-1))
{
[self presentViewController:addNewTask animated:YES completion:NULL];
}
else
{
[taskList removeObjectAtIndex:indexPath.row];
[self.createDaily reloadData];
}
}
The least amount of code way would be:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[self.modelArray removeObjectAtIndex:indexPath.row];
[tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}
These are only required to batch multiple changes together:
[tableView beginUpdates];
[tableView endUpdates];
You can use didSelectRowAtindexPath method of tableview
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[arrayData removeObjectAtIndex:indexPath.row];
[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow: indexPath.row inSection:0]] withRowAnimation:UITableViewRowAnimationRight];
[tableView endUpdates];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[YourArr removeObjectAtIndex:indexPath.row];
[YourTbl reloadData];
}
Under your -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath delegate method,
(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath`
NSArray *toBeDeleted = [[NSArray alloc] initWithObjects: indexPath];
// Data deletion
[tableData removeObjectAtIndex:(indexPath.row)];
[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:toBeDeleted withRowAnimation:UITableViewRowAnimationFade];
[tableView endUpdates];
}
Edit: seems everybody has the same answer!
Add this method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[arrData removeObjectAtIndex:indexPath.row];
[tableView beginUpdates];
[tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow: indexPath.row inSection:0]] withRowAnimation:UITableViewRowAnimationRight];
[tableView endUpdates];
}
Suppose there is Custom Cell A & B of different Height.
Custom Cell A is loaded Default on UITableView. When User will Select Cell A it will remove that Cell and Add Cell B to that Position and vise versa. It will do the animation of re-sizing in Accordion style.
To do this, you should have a property (or key if using a dictionary) in your data array to keep track of what cell you want at each indexPath, and use an if-else statement in cellFroRowAtIndexPath to dequeue the correct cell. In didSelectRowAtIndexPath, you would check that property, set it to the opposite one, and then reload the table. You would also need to implement heightForRowAtIndexPath, and check that same property to determine which height to return.
After Edit:
If you just need to keep track of one selected cell, then create a property (I call it selectedPath) to hold that value and check it in heightForRowAtIndexPath and cellForRowAtIndexPath. I created two cells in the storyboard, one a simple UITableViewCell and the other a custom cell of class RDCell. I'm not sure if this gives the animation you want, but give it a try and see if it's close:
#import "TableController.h"
#import "RDCell.h"
#interface TableController ()
#property (strong,nonatomic) NSArray *theData;
#property (nonatomic) NSIndexPath *selectedPath;
#end
#implementation TableController
- (void)viewDidLoad {
[super viewDidLoad];
self.theData = #[#"One",#"Two",#"Three",#"Four",#"Five",#"Six",#"Seven",#"Eight"];
self.selectedPath = [NSIndexPath indexPathForRow:-1 inSection:0];
[self.tableView reloadData];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return self.theData.count;
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self.selectedPath isEqual:indexPath]) {
return 90;
}else{
return 44;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self.selectedPath isEqual:indexPath]) {
RDCell *cell = [tableView dequeueReusableCellWithIdentifier:#"RDCell" forIndexPath:indexPath];
cell.label.text = self.theData[indexPath.row];
return cell;
}else{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell" forIndexPath:indexPath];
cell.textLabel.text = self.theData[indexPath.row];
return cell;
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSIndexPath *oldPath = self.selectedPath;
self.selectedPath = indexPath;
[self.tableView reloadRowsAtIndexPaths:#[indexPath,oldPath] withRowAnimation:UITableViewRowAnimationAutomatic];
}

You can call [yourTableview reloadData] in didSelectRowAtIndexPath method.
Then in numberOfRowsInSection give a new count. In heightForRowAtIndexpath specify the custom heights.
In cellForRowAtIndexpath add custom cells.
