I am working with table for setting values from the array to a label in a row.
In ios 10 when I select table row it works but in ios 11 when I select a row the cell label value replace with Label text only.
Can any one help.
Here is the code I have done:=
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return arrpickuprequest.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
cell.lblName.text = [[arrpickuprequest objectAtIndex:indexPath.row-1]valueForKey:#"Name"];
cell.btncheck.tag = indexPath.row;
if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:#"Uncheck"])
[cell.btncheck setImage:[UIImage imageNamed:#"uncheck"] forState:UIControlStateNormal];
else
[cell.btncheck setImage:[UIImage imageNamed:#"check"] forState:UIControlStateNormal];
[cell.btncheck addTarget:self action:#selector(purchase_click:) forControlEvents:UIControlEventTouchUpInside];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if (indexPath.row==0) {
if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:#"Uncheck"])
{
for (int i=0; i<[arrpickuprequest count]+1; i++) {
[arrpickuprequestChecked replaceObjectAtIndex:i withObject:#"Check"];
}
}
else
{
for (int i=0; i<[arrpickuprequest count]+1; i++) {
[arrpickuprequestChecked replaceObjectAtIndex:i withObject:#"Uncheck"];
}
}
}
else {
if([[arrpickuprequestChecked objectAtIndex:indexPath.row] isEqualToString:#"Uncheck"])
{
[arrpickuprequestChecked replaceObjectAtIndex:indexPath.row withObject:#"Check"];
}
else
{
[arrpickuprequestChecked replaceObjectAtIndex:indexPath.row withObject:#"Uncheck"];
[arrpickuprequestChecked replaceObjectAtIndex:0 withObject:#"Uncheck"];
}
}
[tblPickupreuest reloadData];
}

I'm having two rows in tableview whenever I am tapping the + button the objects in applesArray are expanding and collapsing. By default + symbol will display on every cell. If I tap for first the button will change to - and tableview cells will expand.
Like the same way in my navigation bar I am having ic_minus image with button background. When the button is in ic_minus state all sections should display normal i.e Apples and Grapes should display.
After, when I click on the ic_minus button it should change into ic_plus image and all sections should expand with their row objects like Apples with apple1, apple2......apple8 should expand and same as with grapesArray also.
I just created an assessment in Core Data. My process is to reorder them using button inside tableview.
I took my dynamic button inside tableview but I cant reorder them in tableview cell please help me out. Its like drag and drop.

At beginning its work properly, But when I scrolled the table the cell did not changed!
I want to show the button at last cell
Cells in a table view are reused when the user scrolls. When you add a button to an instance of your cell prototype and don't remove it, the button remains, even if the cell is used at another index later. This results in what you have on your screenshots.
You should create two cell prototypes in the interface builder and your cellForRow:atIndexPath: should look something like this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Return cell with data
if (indexPath.row < dataArray.count) {
UITableViewCell *cell = [self.myTable dequeueReusableCellWithIdentifier:#"cell_prototype_1"];
[cell.textLabel setText:dataArray[indexPath.row]];
return cell;
}
// If it's the last index, return cell with button
else {
UITableViewCell *cell = [self.myTable dequeueReusableCellWithIdentifier:#"cell_prototype_2"];
return cell;
}
// This won't get called
return [UITableViewCell new];
}
That will be better if you use two different cells otherwise replace the code in your cellForRowAtIndexPath
if (indexPath.row == rowCount -1){}
with
if ( (indexPath.row-15)%10 == 0 ){}
and Put
[cell.textLabel setText:dataArray[indexPath.row]];
in the else part.
and place code just below UITableViewCell *cell....
for(UIView *view in cell.view.subviews){
if([view isKindOfClass: [UIButton class]]){
[view removeFromSuperView];
}
}
I think you need to refresh visible cells, doing:
[tableView reloadRowsAtIndexPaths:[tableView indexPathsForVisibleRows]
withRowAnimation:UITableViewRowAnimationNone];
Also better way to do it would be that you have 2 prototype cells, one for data, one with button. let's sey you give the second one identifier "buttonCell", than you just do this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *idintify = (indexPath.row < rowCount -) ? #"Cell" : #"buttonCell";
UITableViewCell *cell = [self.myTable dequeueReusableCellWithIdentifier:idintify];
if (cell == nil) //initialize
if (indexPath.row < rowCount -1) {
[cell.textLabel setText:dataArray[indexPath.row]];
}
return cell;
}
and in didSelectRowAtIndexPath you increase rowCount and reload data if indexPath.row == rowCount - 1
I am making an inbox module in my app.On first load 20 messages are coming from server.
I want that after 20 messages a label named "load more messages" will be create in UItableview cell.
and after clicking on that label i want to make another call to server.
I had tried following code but it is not working . thanx in advance:(
below is my sample code of cellForRowAtIndexPath and numberOfRowsInSection

As u want a row to be added to tableview that shows Load More Records u can do it in 2 ways either by adding a footer view or every last row, by passing one extra row in the method -(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section and return a particular cell for this row in -(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
for example add one more custom cell in the tableview and add a label and set its text as Load more record and set its reuse identifier as LabelCell
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return self.inboxmessagesarray.count + 1 ;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
//[self performSegueWithIdentifier:#"segueIdentifier" sender:tableView];
if(indexPath.row == [self.inboxmessagesarray count])
{
NSLog(#"load more records");
}
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
__block tablecellTableViewCell *cell= [tableView dequeueReusableCellWithIdentifier:tableviewidentifier];
if(cell == nil)
{
cell = [[tablecellTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:tableviewidentifier];
}
//in the last row
if(indexPath.row == self.inboxmessagesarray.count)
{
cell = [tableView dequeueReusableCellWithIdentifier:#"LabelCell"];
if(cell == nil)
{
cell = [[tablecellTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"LabelCell"];
}
if([self.inboxmessagesarray count] > 0)
cell.hidden = NO;
else
cell.hidden = YES;
return cell;
}
//..rest of the code

you can use this in multiple types here I add in 3 types, customize your self
choice No 1
assume that u get the all data (e.g 100) from server , store in the some NSMutableArray, concept is declare one global int
int loadMoreItems;
in your viewWillAppear
-(void)viewWillAppear:(BOOL)animated
{
loadMoreItems=21; // initially set the count is more than 20
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if ([yourTotalArrayName count]<=loadMoreItems) {
return [yourTotalArrayName count];
}
else {
return loadMoreItems;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier;
// add your data
if (indexPath.row+1<loadMoreItems)
{
cell.lblLoadMoreItems.hidden=YES;
cell.itemsdetails.text = [NSString stringWithFormat:#"%#",[yourTotalArrayName objectAtIndex:indexPath.row]] ;
}
else
{
cell.itemsdetails.hidden=YES;
cell.lblLoadMoreItems.text = #"Load more results...!";
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row+1<loadMoreItems) {
// here do your stuff here
}
else {
loadMoreItems=loadMoreItems+20;
[self.yourtableview reloadData];
}
choice no 2
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Classic start method
// here add your data loaded
if (indexPath.row == [self.yourarrayName count] - 1)
{
cell.lblLoadMoreItems.text = #"Load more results...!";
[self launchReload];
}
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == [self.yourarrayName count] - 1)
{
[self launchReload];
}
}
-(void)launchRelaod
{
// call the webservice
[self.yourtableview reloadData];
}
choiceNo 3
use 2 prototype cell in `UItableView`
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [yourarrayname count] + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *postCellId = #"postCell";
static NSString *moreCellId = #"moreCell";

if ([indexPath row] == [yourarrayname count]) {
cell = [tableView dequeueReusableCellWithIdentifier:moreCellId];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:moreCellId];
}
cell.textLabel.text = #"Load more items...";
cell.textLabel.textColor = [UIColor blueColor];
}
else
{
cell = [tableView dequeueReusableCellWithIdentifier:postCellId];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:postCellId];
}
// show your Data
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([indexPath row] == [yourarrayname count]) {
// call the web service and reload Data of UItableview
}
else
{
//normall selcftion procedure
}
}
Add your label as a Table's footerview.
tableview.tableFooterView = label;
By this you will get your label at the end of your table always.
And for load more action add tap gestures to the label.
If you just want something to show up at the bottom or below your tableView you just implement a quick step:
This will waive any auto layout woes or troubles with a UILabels frame or origins (it will never move)
UIView* footerView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, self.tableView.bounds.size.width, 25)];
UIButton *loadMoreButton = [[UIButton alloc] initWithFrame:CGRectMake(0, 0, 100, 25)];
[loadMoreButton setTitle:#"Load More" forState:UIControlStateNormal];
[loadMoreButton addTarget:self action:#selector(loadMore:) forControlEvents:UIControlEventTouchUpInside];
//More customizing
[footerView addSubview:loadMoreButton];
self.tableView.tableFooterView = footerView;
-(IBAction)loadMoreButton:(id)sender {
//load more from server
}
I am making an app in which i am using buttons in the form of checkboxes in uitableview cell.i am changing images on that checkbox select and unselect state. now i want that when i click on another button then all the cells of table view will be select and image of all the checkboxes of cells will changed? how it can done below is my sample code

[self.tblvie reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation: UITableViewRowAnimationFade];
}
and here is my button in which i click then all the cells of tableview will select and images of all the cells will changed but it is not working
- (IBAction)selectbtns:(id)sender {
static NSString *tableviewidentifier = #"cell";
TablecellTableViewCell *cell= [self.tblvie dequeueReusableCellWithIdentifier:tableviewidentifier];
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"check_box_ok.png"]
forState:UIControlStateNormal];
}
NSMutableArray *totalcheckmarkArray; //add on NSMutablearray in globally
- (void)viewDidLoad {
totalcheckmarkArray =[[NSMutableArray alloc]init];
for (int i=0; i<[self.lblArray count]; i++) // Number of Rows count
{
[self.totalcheckmarkArray addObject:#"NO"];
}
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *tableviewidentifier = #"cell";
TablecellTableViewCell *cell= [self.tblvie dequeueReusableCellWithIdentifier:tableviewidentifier];
if(cell==nil)
{
cell = [[TablecellTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:tableviewidentifier];
}
cell.lblImage.layer.cornerRadius=3.0f;
cell.lblImage.layer.borderWidth=1.0f;
if(![[self.totalcheckmarkArray objectAtIndex:indexPath.row] isEqualToString:#"NO"])
{
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"check_box_ok.png"] forState:UIControlStateNormal];
}
else if ([self.checkimageArray containsObject:[self.lblArray objectAtIndex:indexPath.row]])
{
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"check_box_ok.png"] forState:UIControlStateNormal];
}
else
{
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"uncheck.png"] forState:UIControlStateNormal];
}
cell.buttonCheckbox.tag=indexPath.row;
[cell.buttonCheckbox addTarget:self action:#selector(checkButton:) forControlEvents:UIControlEventTouchUpInside];
cell.lblText.text=[self.lblArray objectAtIndex:indexPath.row];
return cell;
}
selectAll Checkbox
- (IBAction)selectbtns:(id)sender {
for (int i=0; i<[self.lblArray count]; i++)
{
[totalcheckmarkArray replaceObjectAtIndex:i withObject:#"YES"];
}
[self.tblvie reloadData];
}
DeselectAll Checkbox
-(IBAction)deselectall_btnclick:(id)sender
{
for (int i=0; i<[self.lblArray count]; i++)
{
[totalcheckmarkArray replaceObjectAtIndex:i withObject:#"NO"];
}
[self.tblvie reloadData];
}
I can think of two possible solutions. If the following line works in cellForRowAtIndexPath:
if ([self.checkimageArray containsObject:[self.lblArray objectAtIndex:indexPath.row]]) {
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"check_box_ok.png"] forState:UIControlStateNormal];
}
Then just add all the images to self.checkimageAray and then reload the table through [self.tblvie reloadData].
If there is a reason you don't want to reload the table, you could do the following, which will loop through all the cells in the table and execute the changes to each cell:
for (int section = 0; section < [self.tblvie numberOfSections]; section++) {
for (int row = 0; row < [self.tblvie numberOfRowsInSection:section]; row++) {
NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
TablecellTableViewCell *cell= [self.tblvie cellForRowAtIndexPath:cellPath];
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"check_box_ok.png"]
forState:UIControlStateNormal];
}
}
I tend to iterate over every cell when I wish to make a change with an animation. If say you want to animate the checking of the box, the simplest way would be to place the animation block in the iteration of the cells.
If you wish to then unselect a cell, you could do the following:
for (int section = 0; section < [self.tblvie numberOfSections]; section++) {
for (int row = 0; row < [self.tblvie numberOfRowsInSection:section]; row++) {
NSIndexPath* cellPath = [NSIndexPath indexPathForRow:row inSection:section];
TablecellTableViewCell *cell= [self.tblvie cellForRowAtIndexPath:cellPath];
[cell.buttonCheckbox setImage:[UIImage imageNamed:#"uncheck.png"]
forState:UIControlStateNormal];
}
}
Please note that this is not changing your checkimageArray. While the cells are being displayed as selected, all of the images are not in your checkimageArray, and of corse with my solution for unselecting the cell, the images will not be removed from the checkimageArray either.
I would suggest adding all the objects from self.lblArray to checkimageArray where you place the code to set the cells highlighted and remove all objects from checkimageArray when you deselect them all. An example of how to add all images to the array is show in the other answer bellow.
You can do .
- (IBAction)selectbtns:(id)sender
{
self.checkimageArray = [NSArray arrayWithArray:self.lblArray];
[self.tableView reloadData];
}
