can somebody please tell me how can I get a user submitted content(like a post) and automatically append it at the end when I use infinite scroll.To be more specifically,when I would scroll down and reach the end of the page,I would like the page to get more posts and show them(like facebook with news feed).Thank you
Supposed it's a tableView, fetch more data from server when it reaches the end cell.
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
NSInteger index = indexPath.row;
if (index == yourEndCellIndex) {
[self fetchMoreDataFromServer];
}
}
Fetch server data and append it to you data array.
- (void)fetchMoreDataFromServer {
NSArray *dataFromServer = ....;
for (id obj in dataFromServer) {
[self.dataArray addObject:obj];
}
[self.tableView reloadData];
}

I want to add row dynamically. I have tableview list of building names. If some one choose building(didSelectRowAtIndexPath) then respective floors of building should get added dynamically as subrow. Its like maximizing and minimizing the subrow on respective building list selection. How do I do this. Thanks in advance...

may this meet your requirement
Okay, so not to sound mean, but there are almost too many issues here to count.
Let's start with a basic explanation of how tableView's work so that you can start to fix this:
First, the tableView asks how many sections are in the table by calling:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
}
In your code, you simply tell it that it has one section. However, in your later code, when you try to add rows to your table, you tell it that you want to add your rows to a second section (with an index of 1). Therefore, you either need to add these rows to section 0 instead, or update the above method to tell it that, sometimes, there are two sections.
Second, the tableView asks how many rows are in each section of the table by calling:
- (NSInteger)tableView:(UITableView *)tableView
numberOfRowsInSection:(NSInteger)section {
}
In your code, you are simply returning the number of zones. However, like above, you need to include the rows that you have added to your table. If you are adding them to a different section, then you need to return different values, depending on how many rows are in the section with the index asked for in the section variable. If they are all in the same section, then you need to add them up and return the correct value.
Third, the tableView asks for an actual cell for the row by calling:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
}
In your code, you are only returning a cell which has data populated by the indoorZones array, but you also need to supply cells which are configured properly for the specific zone/floor. Again, you either need to determine this by section number or row number as appropriate.
Finally, when you click on a row, the tableview tells you by calling the following method:
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
}
In this method, you need to update your data source that is used by the previous functions so that when they get called again, they will provide the correct data. Your data source must mirror the way that you want your table view to look. In your case, you have an array called indoorZones. This is good if you just want to display a list of zones, which is what you start off doing. However, when you want to add more rows, you need to add more rows to your data source first, so that when the tableView starts this process over, it is already there.
If you want everything to stay in one section, then I would come up with a data source that can include both types of rows, and be able to distinguish between them so that cellForRowAtIndexPath can create the proper type of cell and return it.
If you want two sections, then I would add a second array for the second section (since it is not the same type of data) and return the appropriate values in each of these methods, based on which array you need to use for that section.
I hope this helps!
I followed Simon Lee's tutorial on animating uitableview height change, and it's working amazing! The only problem I seem to be facing is that I can tap several cells, and they all will remain expanded regardless if another is already expanded. I only want one expanded at any given time, and if another is already expanded, for it to be closed before a new one expands.
Simon mentioned that we should "store a single NSIndexPath as the current selected item instead on an array of indexes." I'm not exactly sure how to do this. If anyone could help out that would be awesome!
what you have to do is just add the code below in the tableView delegate method tableView:didSelectRowAtIndexPath: below the line
[selectedIndexes setObject:selectedIndex forKey:indexPath];
code to add
NSArray *key = selectedIndexes.allKeys;
for (int i = 0; i < [key count]; i++) {
if (![[key objectAtIndex:i] isEqual:indexPath]) {
[selectedIndexes setObject:[NSNumber numberWithBool:NO] forKey:[key objectAtIndex:i]];
}
}
Happy Coding :)
Enjoy the Day!!
Yes you can colapse the cells using the delegate methods of UITableView -(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath and - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath :-
First declare the variable to get theindexPath
NSIndexPath *selectedCellIndexPath;
then get the cell's indexPath in didSelectRowAtIndexPath :-
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
selectedCellIndexPath=indexPath;
[tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationBottom];
}
Then do the collapsing and extending and set the lower and upper height:-
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(selectedCellIndexPath != nil
&& [selectedCellIndexPath compare:indexPath] == NSOrderedSame)
return yourCellsExtendedHeightInInteger;
return yourCellsCollapsedHeightInInteger;
}
or use
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(selectedCellIndexPath && indexPath.row == selectedCellIndexPath .row)
{
return 100;
}
return 44;
}
You can see this tutorial also:-
I have a multi-section tableview. In edit mode I allow rows to be moved from one section to another. Once the final row is removed from one section I delete that section. So I am using deleteSection inside moveRowAtIndexPath.
When the final item is moved from the section, the section header disappears as planned. But there is a very strange animation bug, where the moved row seems to 'merge' with the row it is dropped above, and an empty row is displayed at the bottom of the 'to' section (probably because the numberOfRows for that section is correct, but 2 rows are in the same position). Even stranger, when I click the reorder control for this row (not moving the item, simply touching and releasing), the two items 'unmerge'.
I have posted a video demonstrating this.
I have tried wrapping my data changes and view changes in begin/end updates, but to no avail.
I have uploaded a test project here, and I will also post the code below. A couple of points:
I have tried to replicate my data source's format in the demo project, in case this is where the problem originates. The key thing is that my source is a composite array of two other arrays (though I can't see why this would be an issue).
To see the behavior in question, move the two rows in the bottom section, up into the top section. Don't drop them in the last row on the top section though, since this seems to work ok.
Moving rows the other way, from the top section to the bottom section, is buggy in this demo project.
Code (all of this is in the demo project):
I set up my arrays in loadView:
- (void)loadView{
array1 = [NSMutableArray array];
[array1 addObject:#"test 0"];
[array1 addObject:#"test 1"];
[array1 addObject:#"test 2"];
array2 = [NSMutableArray array];
[array2 addObject:#"test a"];
[array2 addObject:#"test b"];
[super loadView];
}
I also have a method that returns a combination of these arrays - this is used as the data source:
- (NSMutableArray *)sourceArray{
NSMutableArray *result = [NSMutableArray array];
if (array1.count > 0) {
[result addObject:array1];
}
if (array2.count >0) {
[result addObject:array2];
}
return result;
}
Which allows for very simple number of rows/sections:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return self.sourceArray.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [[self.sourceArray objectAtIndex:section] count];
}
Standard Cell/Header formatting:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell.textLabel.text = [[self.sourceArray objectAtIndex:indexPath.section] objectAtIndex:indexPath.row];
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section {
return [NSString stringWithFormat:#"Section %i", section];
}
This is where I do the magic
// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
NSMutableArray *fromArray = [self.sourceArray objectAtIndex:fromIndexPath.section];
NSMutableArray *toArray = [self.sourceArray objectAtIndex:toIndexPath.section];
NSString *movedObject = [[self.sourceArray objectAtIndex:fromIndexPath.section] objectAtIndex:fromIndexPath.row];
[fromArray removeObject:movedObject];
[toArray insertObject:movedObject atIndex:toIndexPath.row];
if ([self.tableView numberOfRowsInSection: fromIndexPath.section] == 0) {
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationFade];
}
}
I notice that the row that comes from the to-be-deleted section is the one that disappears until you retouch the order control.
I suspect that when this datasource method is called by the tableview, its state is still in the middle of performing the move, so calling 'deleteSections' will make the table try and delete the row you're moving. It's not so much of a merge as the fact that it's fading away at the same rate as the section header, and the one below it is just scooting back up to fill the space.
Tapping the control causes the table view to rejigger itself and realize that the row isn't actually gone.
to try and work around this, try running the deletion in the next runloop, via a dispatch call, like:
if ([self.tableView numberOfRowsInSection: fromIndexPath.section] == 0) {
dispatch_async(dispatch_get_main_queue(), ^() {
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationFade];
});
}
this will cause the deletion to run on the main thread still, but allow the 'moveRow' and whatever call stack it happens to be in finish up its logic before the deletion call
Your problem is in the animation. One is being done while another is not yet finished (moving & deleting animation) causing one cell to be drawn upon the other. You can verify this by moving the cells around again. The correct order will then be displayed. According to Apple's docs on the UITableView:
Note: The data source should not call setEditing:animated: from within its implementation of tableView:commitEditingStyle:forRowAtIndexPath:. If for some reason it must, it should invoke it after a delay by using the performSelector:withObject:afterDelay: method.
Therefore to fix this, do this to your code:
if ([self.tableView numberOfRowsInSection: fromIndexPath.section] == 0) {
[self performSelector:#selector(someMethod:) withObject:fromIndexPath afterDelay:1.0];
}
- (void) someMethod:(NSIndexPath *) fromIndexPath {
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationFade];
}
Should work fine. Just change the delay to something shorter that suites you.
On the off chance that your rows or what's inside them can take focus, have you checked that you have called resignFirstResponder or [view endEditing:YES]? We saw this when we used text fields and (IIRC it was iOS 4 version dependent too) left the focus in one of the fields.
You have to reload the tableview after deleting the section. Try this code.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
NSMutableArray *fromArray = [self.sourceArray objectAtIndex:fromIndexPath.section];
NSMutableArray *toArray = [self.sourceArray objectAtIndex:toIndexPath.section];
NSString *movedObject = [[self.sourceArray objectAtIndex:fromIndexPath.section] objectAtIndex:fromIndexPath.row];
[fromArray removeObject:movedObject];
[toArray insertObject:movedObject atIndex:toIndexPath.row];
if ([self.tableView numberOfRowsInSection: fromIndexPath.section] == 0) {
[self.tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationFade];
[self.tableView reloadData];
}
}
Swap the order of fromArray and toArray in your code. If the item has a retain count of 1 prior to removing it from the array, it will have a retain count of 0 before adding it to toArray.
If you swap the order, the item will go from retain count of 1 to 2 then back to 1 when the remove is complete.
I think the UITableViewRowAnimationFade animation is interfering with the UITableViewCell move animation. One thing you can try is to delay the section deletion a little bit late in order for the cell move row animation to finish.
Try replace your code with the following code.
-(void)deleteSection:(NSIndexSet*)indexSet
{
[self.tableView deleteSections:indexSet withRowAnimation:UITableViewRowAnimationFade];
}
// Override to support rearranging the table view.
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath
{
NSMutableArray *fromArray = [self.sourceArray objectAtIndex:fromIndexPath.section];
NSMutableArray *toArray = [self.sourceArray objectAtIndex:toIndexPath.section];
NSString *movedObject = [[self.sourceArray objectAtIndex:fromIndexPath.section] objectAtIndex:fromIndexPath.row];
[fromArray removeObject:movedObject];
[toArray insertObject:movedObject atIndex:toIndexPath.row];
if ([self.tableView numberOfRowsInSection: fromIndexPath.section] == 0) {
[self performSelector:#selector(deleteSection:) withObject:[NSIndexSet indexSetWithIndex:fromIndexPath.section] afterDelay:1.0];
// [self.tableView deleteSections:[NSIndexSet indexSetWithIndex:fromIndexPath.section] withRowAnimation:UITableViewRowAnimationFade];
}
}
a solution that lost animation on last row :
if([listOfItemsOnTransaction count]==indexPath.row){
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil]
withRowAnimation:UITableViewRowAnimationFade];
[self.tableView reloadData];
}else
{
[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObjects:indexPath, nil]
withRowAnimation:UITableViewRowAnimationFade];
}
On the WWDC 11 video 'session 125 - UITableCiew Changes, Tips, Tricks' at 24:30+ Mr Luke Hiesterman is giving a demo which adds a cell to the table view when a cell is selected.
I want to add that functionality to my IOS application, but I can't figure out how to make it.
Some code is not shown in the demo-video. And there is no downloadable source of the demo.
Can anyone help me out?
EDIT:
I can add a new row below the selected row but it is an other custom cell.
(I have a list of contracts which you can accept)
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return ((indexPath.row >= [_contracts count]) ? 40 : 60);
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_contracts count] + ((_addedRow) ? 1 : 0);
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *reuseID = #"contract_cell";
ContractTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:reuseID];
if(!cell)
{
// Load the top-level objects from the custom cell XIB.
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"ContractTableViewCell" owner:self options:nil];
// Grab a pointer to the first object (presumably the custom cell, as that's all the XIB should contain).
cell = [topLevelObjects objectAtIndex:0];
[cell setBackgroundView:[[UIImageView alloc] initWithImage:[UIImage imageNamed:#"contract_cell.png"]]];
}
NSLog(#"row?: %d", indexPath.row);
//I thought this would work... not.
if((indexPath.row >= [_contracts count]))
{
[cell.label setText:#"new"];
}
else
{
Contract *contract = [_contracts objectAtIndex:indexPath.row];
[cell.label setText:#"test"];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(!_addedRow)
{
_addedRow = YES;
[tableView deselectRowAtIndexPath:indexPath animated:NO];
[_tableView insertRowsAtIndexPaths:[NSArray arrayWithObject:[NSIndexPath indexPathForRow:indexPath.row+1 inSection:indexPath.section]] withRowAnimation:UITableViewRowAnimationAutomatic];
}
}
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
return [NSIndexPath indexPathForRow:indexPath.row+1 inSection:indexPath.section];
}
For example I press the first row. A row is added below the first one. But now the cellForRowAtIndexPath.. is called for row 2 (needs to be the new custom)
how can I check if it is a new one?
You need to remember which of your rows is selected to show the added row at the correct index. Currently you're always assuming that the added row is the very last one because you're configuring it in tableView:cellForRowAtIndexPath: only if the index is bigger than your number of contracts.
Say you have five contracts and the third one is selected. if((indexPath.row >= [_contracts count])) is only true for the last row but actually want this condition to be true for the fourth row, so it should be if (indexPath.row == selectedRowIndex + 1) (you need to store the selected row index in some instance variable).
This answer should help you out. It tells you how to put your UITableViewController into "update mode" and then lets you insert new rows (even with animation): UITextField in UITableViewCell - adding new cells
In my app I need to delete multiple rows in a table, edit the table and get a check box beside the table. When checked then the table cells are deleted. It is like the iPhone message app. How can I do this, please help me.
If I understand your question correctly, you essentially want to mark UITableViewCells in some way (a checkmark); then, when the user taps a master "Delete" button, all marked UITableViewCells are deleted from the UITableView along with their corresponding data source objects.
To implement the checkmark portion, you might consider toggling between UITableViewCellAccessoryCheckmark and UITableViewCellAccessoryNone for the UITableViewCell's accessory property. Handle touches in the following UITableViewController delegate method:
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *c = [tableView cellForRowAtIndexPath:indexPath];
if (c.accessoryType == UITableViewCellAccessoryCheckmark) {
[c setAccessoryType:UITableViewCellAccessoryNone];
}
//else do the opposite
}
You might also look at this post regarding custom UITableViewCells if you're wanting a more complex checkmark.
You can set up a master "Delete" button two ways:
The IB approach
The programmatic approach
In either case, eventually a method must be called when the master "Delete" button is pressed. That method just needs to loop through the UITableViewCells in the UITableView and determined which ones are marked. If marked, delete them. Assuming just one section:
NSMutableArray *cellIndicesToBeDeleted = [[NSMutableArray alloc] init];
for (int i = 0; i < [tableView numberOfRowsInSection:0]; i++) {
NSIndexPath *p = [NSIndexPath indexPathWithIndex:i];
if ([[tableView cellForRowAtIndexPath:p] accessoryType] ==
UITableViewCellAccessoryCheckmark) {
[cellIndicesToBeDeleted addObject:p];
/*
perform deletion on data source
object here with i as the index
for whatever array-like structure
you're using to house the data
objects behind your UITableViewCells
*/
}
}
[tableView deleteRowsAtIndexPaths:cellIndicesToBeDeleted
withRowAnimation:UITableViewRowAnimationLeft];
[cellIndicesToBeDeleted release];
Assuming by "edit" you mean "delete a single UITableViewCell" or "move a single UITableViewCell," you can implement the following methods in the UITableViewController:
- (void)viewDidLoad {
[super viewDidLoad];
// This line gives you the Edit button that automatically comes with a UITableView
// You'll need to make sure you are showing the UINavigationBar for this button to appear
// Of course, you could use other buttons/#selectors to handle this too
self.navigationItem.rightBarButtonItem = self.editButtonItem;
}
// Override to support conditional editing of the table view.
- (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath {
// Return NO if you do not want the specified item to be editable.
return YES;
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (void)tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath {
if (editingStyle == UITableViewCellEditingStyleDelete) {
//perform similar delete action as above but for one cell
}
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)fromIndexPath toIndexPath:(NSIndexPath *)toIndexPath {
//handle movement of UITableViewCells here
//UITableView cells don't just swap places; one moves directly to an index, others shift by 1 position.
}
You can put 1 UIButton lets call it "EDIT" and wire up it to IBAction. In IBAction write so you will be able to do as per your requirement.
-(IBAction)editTableForDeletingRow
{
[yourUITableViewNmae setEditing:editing animated:YES];
}
This will add round red buttons on the left hand corner and you can click on that Delete button will appear click on that and row will be deleted.
You can implement delegate method of UITableView as following.
-(UITableViewCellEditingStyle)tableView: (UITableView *)tableView editingStyleForRowAtIndexPath: (NSIndexPath *)indexPath
{
//Do needed stuff here. Like removing values from stored NSMutableArray or UITableView datasource
}
Hope it helps.
you want to be looking for deleteRowsAtIndexPath, with all your code squeezed between [yourTable beginUpdates] & [yourTable endUpdates];
