In my application i have used the setAccessoryType,While searching the content it shows the some set of datas in tabel view with accesory button,When i clear the search it the tabelview get reloaded .Datas cleared but accessory arrow stays there itself .Here my code,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"CellIdentifier";
UILabel *l1;
UITableViewCell *cell = (UITableViewCell *)[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)
{
l1=[[UILabel alloc]initWithFrame:CGRectMake(0, 5, 690, 40)];
}else{
l1=[[UILabel alloc]initWithFrame:CGRectMake(0, 5, 310, 40)];
}
l1.textColor=[UIColor whiteColor];
l1.backgroundColor=[UIColor clearColor];
[l1 setFont:[UIFont boldSystemFontOfSize:14.0]];
l1.textAlignment=UITextAlignmentLeft;
l1.text=[[existingResults objectAtIndex:0] valueForKey:#"food_name"];
l1.textColor=[UIColor blackColor];
[cell addSubview:l1];
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
return cell;
}
tabelview reloading code
-(void)txttapped:(id)sender{
[[WebService sharedInstance]foodsearch:txtSearch.text withCompletionHandler:^(BOOL result)
{
if(result)
{
NSLog(#"Success");
NSManagedObjectContext *context = [[DataAccessLayer sharedInstance] managedObjectContext];
existingResults = [context fetchObjectsForEntityName:NSStringFromClass([Food class]) withSortColumn:nil withSortDescending:FALSE withPredicate:nil];
[existingResults retain];
[tableView reloadData];
[self.progress hide:YES];
}
else
{
if (txtSearch.text.length==0)
{
[tableView reloadData];// tabelview reloads here
}
else
{
NSLog(#"Failure");
UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:#"Alert Message" message:#" Failed" delegate:nil cancelButtonTitle:#"Ok" otherButtonTitles:nil];
[alertView show];
[alertView release];
[self.progress hide:YES];
}
}
}];
}
How to hide the accessory view when tabel has no value?Please help me to sort it out
Try ,
if([[[existingResults objectAtIndex:0] valueForKey:#"food_name"] length] > 0)
{
[cell setAccessoryType:UITableViewCellAccessoryDisclosureIndicator];
}
else
{
[cell setAccessoryType:UITableViewCellAccessoryNone];
}

I want to switch to next view immediately using push view controller, so using below method to fetch data from web services. But this is not updating UITableView.

Below is cellForRowAtIndexPath method.
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{

}
else{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;

[cell.contentView addSubview:lblEventName];
if([copyArr count] >0)
{
lblEventName.text = [copyArr objectAtIndex:indexPath.row];
}
else{
lblEventName.text = [self.mFrndNameArr objectAtIndex:indexPath.row];
}
asyncImageView = [[AsyncImageView alloc]initWithFrame:CGRectMake(1, 3, 85, 54)];
[asyncImageView loadImageFromURL:[NSURL URLWithString:imageUrlString]];
[cell.contentView addSubview:asyncImageView];
cell.textLabel.backgroundColor = [UIColor colorWithRed:240.0/255.0 green:240.0/255.0 blue:240.0/255.0 alpha:1.0];
cell.contentView.backgroundColor = [UIColor colorWithRed:240.0/255.0 green:240.0/255.0 blue:240.0/255.0 alpha:1.0];
return cell;
}
The text data is fetched but images are not fetched until table scrolled. But if i use this way it shows the images also but switches to next view after all dat is fetched.
// vewDidLoad
[self setImage];
Please guide for above, is the way iam using threads wrong or any other way or method needs to be used here.
Since you are updating data in seperate thread ,You have to execute the reload on the main thread itself
instead of this
[self.mFriendsTable reloadData];
use this
[self.mFriendsTable performSelectorOnMainThread:#selector(reloadData) withObject:nil waitUntilDone:YES];
I have a problem: update data in UITableView. I want to get new data from parseXML that response from Server and them update new data to UITableView. **I used beloww code, but it does not show new data on Table View. I wrote a UpdateArray() function to check new data and then I compare 2 Array,if diff [Array count] then I call [tableview reloadData];

Can you help me? Thanks in advance.
I dont See that you call reloadData.
EDIT:
You must check that
1-Temp is having objects i mean that [temp count] is not returning zero.
2-The if condition that checks the two arrays is triggered . I mean that reload data is called.
3-You can make a breakpoint after cell.contetview addsubview and check what the cell contain now?
before you call
[_tableView reloadRowsAtIndexPaths:[_tableView indexPathsForVisibleRows]
withRowAnimation:UITableViewRowAnimationNone];
you have to call
[_tableView beginUpdates];
...
[_tableView endUpdates];
or call
[_tableView reloadData];
If you refresh table view then try this line & check:
[[self mytableview] reloadData];
mytableview is obj of tableview you give here your tableview object.
I made tableView with filteredReservations array wich contains Rezervacija objects.
I added custom button "board", and when button is clicked, I ask with alert view to confirm this and then sending request to server. When receive server's response I need to delete row from table and object from filteredReservations array.
When I delete first row it's ok, but after that in filteredReservations instead of Rezervacija object, I got UIButton objects! I don't know HOW :)
Code:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return([filteredReservations count]);
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:MyIdentifier] autorelease];
}
Reservation *reservation = [filteredReservations objectAtIndex:indexPath.row];
NSString *label = [[NSString alloc] initWithFormat:#"%# (%d)", reservation.name, reservation.seatsNumber];
cell.textLabel.text = label;
[label release];
[reservation release];
tableView.allowsSelection = FALSE;
UIButton *cellButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[cellButton setFrame:CGRectMake(430.0, 2.0, 106.0, 40.0)];
[cellButton setTitle:#"Board" forState:UIControlStateNormal];
[cellButton addTarget:self action:#selector(BoardPassengers:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:cellButton];
cellButton.tag = indexPath.row;
return cell;
}
-(void)BoardPassengers:(id)sender{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Question" message:#"Do you want to board passengers?"
delegate:self cancelButtonTitle:#"Odustani" otherButtonTitles:#"Da", nil];
[alert show];
[alert release];
passengerForBoarding = [NSIndexPath indexPathForRow:((UIControl*)sender).tag inSection:1];
}
- (void)alertView:(UIAlertView *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex
{
// the user clicked one of the OK/Cancel buttons
if (buttonIndex == 0)
{
NSLog(#"cancel");
}
else
{
Reservation *reservationNew = [filteredReservations objectAtIndex:passengerForBoarding.row];
NSString *reservationId = [[NSString alloc] initWithFormat:#"%d",reservationNew.reservationId];
params = [NSDictionary dictionaryWithObjectsAndKeys: #"1", #"tour_id", #"1", #"bus_number",reservationId, #"reservation_id", nil];
[[RKClient sharedClient] post:#"/service/boardingToBus.json" params:params delegate:self];
[DSBezelActivityView newActivityViewForView:self.view withLabel:#"Boarding..."];
}
}
- (void)request:(RKRequest*)request didLoadResponse:(RKResponse*)response {
if([[request resourcePath] isEqualToString:#"/service/boardingToBus.json"]){
if([[response bodyAsString] isEqualToString:#"ERROR"]){
[DSBezelActivityView removeViewAnimated:YES];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:nil message:#"Error."
delegate:self cancelButtonTitle:#"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}else{
[DSBezelActivityView removeViewAnimated:YES];
[filteredReservations removeObjectAtIndex:passengerForBoarding.row];
[self.tableView reloadData];
//[self.tableView beginUpdates];
//[self.tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:passengerForBoarding]
// withRowAnimation:UITableViewRowAnimationFade];
// NSLog(#"%i", passengerForBoarding.row);
//[self.tableView endUpdates];
}
}
}
It sounds like you need to make sure the table view is explicitly aware of how many filtered reservations it needs to display.
// assuming only one section for your table view
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return([filteredReservations count]);
}
For more info:
http://developer.apple.com/library/ios/documentation/UIKit/Reference/UITableViewDataSource_Protocol/Reference/Reference.html#//apple_ref/occ/intfm/UITableViewDataSource/tableView:numberOfRowsInSection:
Hey you can get the value of "Reservation ID" By this.
-(void)BoardPassengers:(id)sender{
Reservation *reservationNew = [filteredReservations objectAtIndex:[sender tag]];
NSString *reservationId = [NSString StringWithFormat:#"%d",reservationNew.reservationId];}
Or you can use this value anywhere you want like you have mentioned via alert-box.
I have designed a custom table cell. which displays product information.
When i implement CellForRowAtIndexPath I am doing this.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *sectionTableCellIdentifier = [[NSString alloc] initWithFormat:#"GLItemTableCellIdentifierNumber%d",indexPath.section];
// UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"GLItemDetailsTableCellIdentifier"];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:sectionTableCellIdentifier];
if (cell == nil)
{
NSDictionary *dict = [self.listData objectAtIndex:indexPath.row];
ItemsListTableCell *cell = (ItemsListTableCell *)[tableView dequeueReusableCellWithIdentifier:sectionTableCellIdentifier];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"ItemsListTableCell"
owner:self options:nil];
for (id oneObject in nib)
{
if ([oneObject isKindOfClass:[ItemsListTableCell class]])
{
cell = (ItemsListTableCell *)oneObject;
}
}
NSString *priceinfo = [[NSString alloc] initWithFormat:#"$%#",[dict objectForKey:#"CurrentPrice"]];
NSString *sizeinfo = [[NSString alloc] initWithFormat:#"Size: %#",[dict objectForKey:#"Size"]];
NSString *upcInfo = [[NSString alloc] initWithFormat:#"UPC: %#",[dict objectForKey:#"ID"]];
NSString *strQuantity = [[NSString alloc] initWithFormat:#"%#",[dict objectForKey:#"Quantity"]];
cell.lblProductName.text = [dict objectForKey:#"Name"];
cell.lblSize.text = sizeinfo;
cell.lblBrand.text = [dict objectForKey:#"BrandName"];
cell.lblProductCode.text = upcInfo;
cell.lblQuantity.text = strQuantity;
cell.lblPrice.text = priceinfo;
cell.lblStoreName.text = [dict objectForKey:#"StoreName"];
cell.isSelected = NO;
[cell.btnSelected addTarget:self action:#selector(cellButtonTapped:)
forControlEvents:UIControlEventTouchUpInside];
[upcInfo release];
[priceinfo release];
[strQuantity release];
[sizeinfo release];
return cell;
}
return cell;
}
now for the click event I am doing
- (IBAction)cellButtonTapped:(id)sender
{
UIView *contentView = [sender superview];
ItemsListTableCell *cell = (ItemsListTableCell *)[contentView superview];
NSIndexPath *indexPath = [table indexPathForCell:cell];
NSUInteger buttonRow = [[self.table
indexPathForCell:cell] row];
NSUInteger buttonSection = [[self.table
indexPathForCell:cell] section];
NSLog(#"Index Path Row : %d",buttonRow);
NSLog(#"Index Path Section : %d",buttonSection);
ItemsListTableCell *buttonCell =
(ItemsListTableCell *)[table cellForRowAtIndexPath:indexPath];
if (buttonCell.isSelected == YES)
{
buttonCell.isSelected = NO;
UIImage *image = [[UIImage imageNamed:#"checkbox-empty.png"] autorelease];
[buttonCell.btnSelected setImage:image forState:UIControlStateNormal];
}
else
{
buttonCell.isSelected = YES;
UIImage *image = [[UIImage imageNamed:#"checkbox-full.png"] autorelease];
[buttonCell.btnSelected setImage:image forState:UIControlStateNormal];
}
self.txtQuantity.text = buttonCell.lblQuantity.text;
NSString *buttonTitle = buttonCell.lblProductName.text;
UIAlertView *alert = [[UIAlertView alloc]
initWithTitle:#"You tapped the button"
message:[NSString stringWithFormat:
#"You tapped the button for %#", buttonTitle]
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
The Problem is when i click on check button it is going to the event. but I am unable to detect what is the parent cell . as there are some values in cell.
Instead of creating such an event (IBAction), you could do all of these in
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
if (selectedCell.accessoryType == UITableViewCellAccessoryNone)
{
selectedCell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
if (selectedCell.accessoryType == UITableViewCellAccessoryCheckmark)
{
selectedCell.accessoryType = UITableViewCellAccessoryNone;
}
}
If you want a checkmark of your own style, you could set them up here and finish off things. Makes stuff easier !
I am having Tableview which shows comments on facebook post. I am getting comments in Array and comments Id in second array ..I have taken one uibutton in tableview cell. on that button I want to get comment id of particular comment so that I can pass that id to like method..But It is always taking id Of last comment..How can I ID of comment on Button.tag property,, My code is :
- (NSInteger)tableView:(UITableView *)atableView numberOfRowsInSection:(NSInteger)section {
return [[facebook comments] count];
}
- (UITableViewCell *)tableView:(UITableView *)atableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {

message:#"" delegate:nil
cancelButtonTitle:#"Ok" otherButtonTitles:nil ];
[alert show];
[alert release];
}
Please help
The problem, which you are facing because you are always using the last like button.
You require to make few changes, Append an in the function name like likeComment:.
[like addTarget:self action:#selector(likeComment:) forControlEvents:UIControlEventTouchUpInside];
And modify your likeComment method like below.
- (void )likeComment:(id) sender {
UIButton* myLikeButton = (UIButton*)sender;
NSString *idStr = [NSString stringWithFormat:#"%#/likes",[[facebook commentId]objectAtIndex:myLikeButton.tag]];
[fbGraph doGraphPost:idStr withPostVars:nil];
UIAlertView *alert = [[UIAlertView alloc]initWithTitle:#"You like this"
message:#"" delegate:nil
cancelButtonTitle:#"Ok" otherButtonTitles:nil ];
[alert show];
[alert release];
}
