popover tableview shows then disappears - ipad

On a button click I am showing a popover view which is a tableview.
Everything seems to work and the view shows but then disappears in less than a second.
The tableview contains a list of strings and I set the tablecell to be show checkmark.
I notice that table shows all items checked in the split second it is displayed
Anyone knows what I am missing.
Thanks
Hassan
Code to show the popover
- (void) prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"WholesalersList"]){
AppDelegate *appDelegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
WholesalersViewController *vc = segue.destinationViewController;
vc.wholesalers = [appDelegate.wholesalers mutableCopy];
if ([segue isKindOfClass:[UIStoryboardPopoverSegue class]]){
self.wholesalersPopoverController = [(UIStoryboardPopoverSegue *)segue popoverController];
[self.wholesalersPopoverController setPopoverContentSize:CGSizeMake(334, 334)];
//[self.wholesalersPopoverController setDelegate:self];
}
}
}
Code in the popover tableview
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)theTableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)theTableView numberOfRowsInSection:(NSInteger)section {
if ([self.wholesalers count] == 0) {
return 1;
}
else {
return [self.wholesalers count];
}
}
#pragma mark Table view delegate
- (UITableViewCell *)tableView:(UITableView *)theTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self.wholesalers count] == 0) {
return nil;
}
else {
static NSString *CellIdentifier = #"WholesalerCell";
UITableViewCell *cell = [theTableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell.
Wholesaler *ws = (Wholesaler *)[self.wholesalers objectAtIndex:indexPath.row];
cell.textLabel.text = ws.name;
return cell;
}
}
- (CGFloat)tableView:(UITableView *)theTableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 44;
}
- (void)tableView:(UITableView *)theTableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
}
- (void)tableView:(UITableView *)theTableView accessoryButtonTappedForRowWithIndexPath:(NSIndexPath *)indexPath {
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return NO; // The table view should not be re-orderable.
}

Are calling the dismissPopover:Animated anywhere in the code like mistakenly in the IBAction method for the button or you dont have an IBAction method?

Pass array of images from multiple UITableView selected cells

I am having such an issue right now. I have a UIViewController that has a UITableView, I have it set up so that when the UITableView is in editing mode it returns 3 - circles with the check marks. My UITableView has custom cells with in image and text. When I put the UITableView in edit mode, I am trying to pass an array of the images from multiple selected rows to a second view controller to use those images in a collection view, but I am just having a hard time passing the array of images. Any suggestions would be appreciated.
here is my TableView code:
-(void)didTapEditBUtton:(id)sender{
if ([self.ribbonTableView isEditing]) {
viewButton.hidden = YES;
headerLabel.hidden = NO;
[ribbonTableView setEditing:NO animated:YES];
[selectButton setTitle:#"select"];
}
else {
[selectButton setTitle:#"Cancel"];
// Turn on edit mode
headerLabel.hidden = YES;
viewButton.hidden = NO;
[ribbonTableView setEditing:YES animated:YES];
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection (NSInteger)section{
return [ribbonsArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
RibbonCustomCell *cell = (RibbonCustomCell *) [ribbonTableView dequeueReusableCellWithIdentifier:#"RibbonDetail"];
if (cell != nil)
{
RibbonsInfo *ribbonsInfo = [ribbonsArray objectAtIndex:indexPath.row];
//NSLog(#"%#", ribbonsInfo);
//Ribbon Image
cell.ribbonImageView.image = ribbonsInfo.ribbonImage;
cell.ribbonLabel.text = ribbonsInfo.ribbonName;
}
return cell;
}
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return 3;
}
-(void)tableView:(UITableView *)tableView didSelectRowsAtIndexPath:(NSIndexPath *)indexPath{
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath{
}
You should take the property of NSMutableArray...
#property (nonatomic, strong) NSMutableArray *selectedImages;
- (void)viewDidLoad {
[super viewDidLoad];
self.selectedImages = [NSMutableArray new];
}
now when you select or deselect the cell the delegates are called -
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"%#",indexPath);
RibbonsInfo *ribbonsInfo = [ribbonsArray objectAtIndex:indexPath.row];
[self.selectedImages addObject:ribbonsInfo.ribbonImage];
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSLog(#"%#",indexPath);
if (self.selectedImages.count > 0) {
[self.selectedImages removeObjectAtIndex:indexPath.row];
}
}
-(UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return 3;
}
Now the selectedImages array contains the selected cell images and you can pass this array.
Hope it will solve your problem.

How to Unhide stepper when we select particular row in tableview

I have created a stepper in a CustomCell of a UITableView. However, I would like the stepper to only be visible when a particular row is selected. To this end, I tried the following:
In tableView:cellForRowAtIndexPath:
cell.customStepper.hidden=NO;
and in tableView:didSelectRowAtIndexPath:
cell.customStepper.hidden=YES;
But the stepper is still hidden. What am I missing?
#interface BRNCategoryViewController ()
{
NSMutableArray *arySelectCategory;
NSMutableArray *aryCategory;
}
- (void) viewDidLoad
{
arySelectCategory=[NSMutableArray new];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return aryCategory.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
BRNCategoryCell *cell=[[BRNCategoryCell alloc]initWithOwner:self];
if ([arySelectCategory containsObject:[aryCategory objectAtIndex:indexPath.row]])
{
cell.customStepper.hidden = NO;
}
else
{
cell.customStepper.hidden = YES;
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[tableView deselectRowAtIndexPath:indexPath animated:YES];
if ([arySelectCategory containsObject:[aryCategory objectAtIndex:indexPath.row]])
{
[arySelectCategory removeObject:[aryCategory objectAtIndex:indexPath.row]];
}
else
{
[arySelectCategory addObject:[aryCategory objectAtIndex:indexPath.row]];
}
[tblEventCategory reloadData];
}
In cellForRowAtIndexPath
cell.customStepper.hidden=YES;
And
In didSelectRowAtIndexPath
VideosCell *cell = (VideosCell *)[tableView cellForRowAtIndexPath:indexPath];
cell.customStepper.hidden = NO;

Detail view not updating when UITableView rows are re-ordered

I have a UITableView that pushes to a Detail ViewController. In my tableview, my rows are draggable/re-arrangeable. However, when the rows are switched, the path stays the same when selecting the rows and the Detail View is presented. Example: TableView Re-order Pic
If I were to switch the "Milk" row with the "Gym" row, then select "Gym", the detail view would still return the details of the milk row.
How do I fix this so that the path of the rows switch appropriately as they do?
.m :
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self->newArray count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSDictionary *theFood = [values objectAtIndex:indexPath.row];
cell.textLabel.text = [theFood valueForKey:#"name"];
cell.detailTextLabel.text = [theFood valueForKey:#"price"];
return cell;
}
- (IBAction) EditTable:(id)sender
{
if(self.editing)
{
[super setEditing:NO animated:NO];
[_myTableView setEditing:NO animated:NO];
// [_myTableView reloadData];
[self.navigationItem.leftBarButtonItem setTitle:#"Edit"];
[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStylePlain];
}
else
{
[super setEditing:YES animated:YES];
[_myTableView setEditing:YES animated:YES];
// [_myTableView reloadData];
[self.navigationItem.leftBarButtonItem setTitle:#"Done"];
[self.navigationItem.leftBarButtonItem setStyle:UIBarButtonItemStyleDone];
}
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
if( fromIndexPath == toIndexPath ) {
return;
}
NSDictionary *moveFood = [self->newArray objectAtIndex:fromIndexPath.row];
[self->newArray removeObjectAtIndex:fromIndexPath.row];
[self->newArray insertObject:moveFood atIndex:toIndexPath.row];
}
- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender {
if ([segue.identifier isEqualToString:#"detailSegue"]) {
NSIndexPath *indexPath = [self.myTableView indexPathForSelectedRow];
DetailViewController *detailVC = segue.destinationViewController;
detailVC.detailFood = [values objectAtIndex:indexPath.row];
}
}
When you switch the rows you should also update your data source. Otherwise when tableView's didSelect method is called it would access the wrong object in your data source array.
So in –tableView:moveRowAtIndexPath:toIndexPath: switch the location of the objects that were switched.
Special thanks to #HotLicks for helping me!
The problem was I didn't change my datasource for the detail view from values NSArray to my newArray NSMutableArray after the update in my tableView:moveRowAtIndexPath:toIndexPath: method!

How to move uitableview custom cell?

I use custom cell.I want to move this cell (change position of the cells)
i used this delegations
UITableViewDataSource,UITableViewDelegate
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *Cellidentifier = #"Celledit";
CellEdit *editCell =[tableView dequeueReusableCellWithIdentifier:Cellidentifier];
if (!editCell) {
editCell = [[CellEdit alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:Cellidentifier];
}
MItem *mItem = [mItems objectAtIndex:[indexPath row]];
---------------------------------
// set data 3 labales in the cell
---------------------------------
editCell.editdelegate = self;
return editCell;
editcell is my custom cell
[_tableViewEdit setEditing:YES animated:YES]; this line put in - (void)viewDidLoad
i want to edit it always
// table view change cells
- (UITableViewCellEditingStyle) tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewCellEditingStyleNone;
}
- (BOOL) tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (void) tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath {
NSInteger sourceRow = sourceIndexPath.row;
NSInteger destRow = destinationIndexPath.row;
id object = [minutesItems objectAtIndex:sourceRow];
[minutesItems removeObjectAtIndex:sourceRow];
[minutesItems insertObject:object atIndex:destRow];
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath{
for (UIControl *control in cell.subviews)
{
if ([control isMemberOfClass:NSClassFromString(#"UITableViewCellReorderControl")] && [control.subviews count] > 0)
{
for (UIControl *someObj in control.subviews)
{
if ([someObj isMemberOfClass:[UIImageView class]])
{
UIImage *img = [UIImage imageNamed:#"logocoffee.png"];
((UIImageView*)someObj).frame = CGRectMake(0.0, 0.0, 43.0, 43.0);
((UIImageView*)someObj).image = img;
}
}
}
}
}
}
to move the cell simulator not showing right side control icon
why this?
that means cant move costume cells?
Try this code,
You should use below two method,
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
Use this method for moving the row
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
[label1array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
[label2array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
[label3array exchangeObjectAtIndex:fromIndexPath.row withObjectAtIndex:toIndexPath.row];
}
Custom cells can be moved as well.
From your code samples we don't see where you are setting your tableview in the editing mode.
Perhaps the issue is because you are never setting the editing mode.
If so, try to add an Edit button in the title bar for example, which should be linked to a method such as:
- (IBAction) EditTable:(id)sender{
if(self.editing)
{
[super setEditing:NO animated:NO];
[yourTableView setEditing:NO animated:NO];
[yourTableView reloadData];
[self.navigationItem.leftBarButtonItem setTitle:#"Edit"];
}
else
{
[super setEditing:YES animated:YES];
[yourTableView setEditing:YES animated:YES];
[yourTableView reloadData];
[self.navigationItem.leftBarButtonItem setTitle:#"Done"];
}
}
I think this one should resolve your issue.
Edit: To resume in your case, as a minimum, you only need to set your table view in the editing mode in viewDidLoad, and to update it if needed:
[yourTableView setEditing:YES animated:YES];
[yourTableView reloadData];
and to implement both callbacks:
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
//Even if the method is empty you should be seeing both rearrangement icon and animation.
}
I tried with custom cells and it's working fine.

iOS edit table view not working

I'm fairly new to this and am stuck on a problem. I can't get the ability to edit a table view i've created...
I have a button on the top right corner of the app that says "Edit" and - (IBAction)editTable:(id)sender, I've tried numerous attempts to get to edit this list I've created...
#implementation XYZViewController
#synthesize animalNames;
- (void)viewDidLoad
{
[super viewDidLoad];
//create array called animal names
animalNames = [[NSArray alloc]initWithObjects:
#"Cow",
#"Dog",
#"Cat",
#"Dear",
#"Penguin",
#"Lion",
#"Leapord",
#"Eal",
#"Snake",
#"Moth",
#"Cheetah",
#"Turtle"
, nil];
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [self.animalNames count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *identifier = #"MainCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier];
}
cell.textLabel.text = [self.animalNames objectAtIndex:indexPath.row];
return cell;
}
- (IBAction)editTable:(id)sender
{
NSLog(#"Editing");
[super setEditing:TRUE];
[self.tableView setEditing:TRUE];
self.editing = YES;
}
#end
Using Xcode 5.
You need to implement following methods to support table view editing:
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath
{
// Return NO if you do not want the specified item to be editable.
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath
{
return UITableViewCellEditingStyleDelete;
}
- (BOOL)tableView:(UITableView *)tableView shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath
{
return NO;
}
You should declare animalNames as NSMutableArray as you are going edit it. Then you need to override some delegate methods to perform edit in tableview.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{
NSString *sourceItem = _animalNames[sourceIndexPath.row];
[_animalNames removeObjectAtIndex:sourceIndexPath.row];
[_animalNames insertObject:sourceItem atIndex:destinationIndexPath.row];
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath{
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
if (editingStyle == UITableViewCellEditingStyleDelete){
[_animalNames removeObjectAtIndex:indexPath.row];
[_tableView deleteRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationFade];
}
}
You can stop editing in editTable method like
- (IBAction)editTable:(id)sender
UIBarButtonItem *button = (UIBarButtonItem *)sender;
if ([button.title isEqualToString:#"Edit"]) {
button.title = #"Done";
[self.tableView setEditing:TRUE];
} else {
button.title = #"Edit";
[self.tableView setEditing:NO];
}
}
Hope this will help you
To edit the table view you need to call
[self.tableView setEditing:YES animated:YES]; on the table which you are using then
You have to implement the delegate method
tableView:commitEditingStyle:forRowAtIndexPath:
method to enable the deleting of rows. In order to delete the rows you need to use
Then Do this..
-(void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath
{
//Remove the object at the index we need to delete
[YourTableArray removeObjectAtIndex:indexPath.row];
//Delete the rows at the Indexpath.
[YourTable deleteRowsAtIndexPaths:[[NSArray alloc]initWithObjects:indexPath, nil] withRowAnimation:UITableViewRowAnimationRight];
[reminder_table reloadData];
//Set the table to editing NO.
[YourTable setEditing:NO animated:YES];
}
