how to display a number from 1 to array count in a table row .
am using following code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
// NSInteger WeekList=[WeekArry count];
}
NSInteger row = indexPath.row;
cell.textLabel.text=[NSString stringWithFormat:#"Week %ld",(long)row];
NSLog(#"row%ld",(long)indexPath.row);
// Configure the cell...
return cell;
}
if (row == array.count) {
cell.textLabel.text=[NSString stringWithFormat:#"Week %ld",(long)row];
}else{
cell.textLabel.text=[NSString stringWithFormat:#"Week %ld",(long)row + 1];
}

I have the following implementation, where I am adding a footerview as a customcell. However, if there is no content, I do not want to show the last cell, if there is I want to show it.
In my current implementation, it always displays the last cell.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.adminOrderElements count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return adminOrderElements[section].products.count + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}
There is one option that you can make cellHeight to 0.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(CHECK_IF_NO_CONTAIN)
return 0;
return 40;// Normal height as you want
}
I think you can add condition in else clause like if certain condition is met then you want to display this cell other wise not...
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else //Here add your condition here if you have content for the section like I think this condition might work [adminOrderElements[indexPath.section].notes length]>0
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}
Its quite simple with UITableView delegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (dataObjects.count == 0){
return 0;
}
return dataObjects.count;
}
I am trying to implement multiselection in table view. But it is not working. When I add the below code it just shows me the single section for the elements in the table view. When I remove this line from code then I am able to select but not able to deselect the items.
Removed line code:multi selection works but not able to deselect
for (i=0; i<[arr_selectedCells count]; i++) {
NSInteger currentValue = [(NSNumber *)[arr_selectedCells objectAtIndex:i] integerValue];
if (currentValue==indexPath.row) {
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
}
correct.
Code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
cell.textLabel.text=user_friend.name;
NSLog(#"name is %#",user_friend.name);
int i;
for (i=0; i<[arr_selectedCells count]; i++)
{
NSInteger currentValue = [(NSNumber *)[arr_selectedCells objectAtIndex:i]integerValue];
if(currentValue==indexPath.row)
{
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType=UITableViewCellAccessoryNone;
}
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(![arr_userFriends containsObject:[NSNumber numberWithInteger:indexPath.row]])
{
[arr_selectedCells addObject:[NSNumber numberWithInteger:indexPath.row]];
}
else
{
[arr_selectedCells removeObject:[NSNumber numberWithInteger:indexPath.row]];
}
NSLog(#"numr is %ld",(long)indexPath.row);
[tableView reloadData];
}
Please tell me where I am going wrong?
i just edited your code! and i hope it works for you
tableView CellForRowAtIndexPath
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
cell.textLabel.text=user_friend.name;
if([arr_selectedCells containsObject:user_friend.name])
cell.accessoryType = UITableViewCellAccessoryCheckmark;
else
cell.accessoryType = UITableViewCellAccessoryNone;
return cell;
}
didSelectRowAtIndexPath
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
if([arr_selectedCells containsObject:user_friend.name])
{
[arr_selectedCells removeObject:user_friend.name];
}
else
{
[arr_selectedCells addObject:user_friend.name];
}
[tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationNone];
}
try these
tableView.allowsSelection=YES;
tableView.allowsSelectionDuringEditing = YES;
I want to divide the cells in groups as per condition but i am getting repeated values where i am wrong.
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 5;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(section == 0)
{
return 1;
}
else if(section == 1)
{
return 6;
}
else if(section ==2)
{
return 2;
}
else
{
return [arrControls count]-9;
}
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.textLabel.text = [arrControls objectAtIndex:indexPath.row];
return cell;
}
Use an array of NSMutableArrays for each section.
NSMutableArray *arrays[5];
for (int i = 0; i < 5;i++)
{
arrays[i] = [[NSMutableArray alloc]init];
}
[arrays[0] addObject:#"add Your objects in section 0"];
[arrays[1] addObject:#"add Your objects in section 1"];
[arrays[2] addObject:#"add Your objects in section 2"];
etc..
Then.
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
array[section].count
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 5;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.textLabel.text = [array[indexPath.section] objectAtIndex:indexPath.row];
return cell;
}
inside your cellForRowAtIndexPath , u need to return different cells for different section
Let say u have the 3 custom classes( with inferface for all of them ) inherited from UITableViewCell
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(inderPath.Section ==0 )
{
//assuing that custom class name is detailTableViewCell.h and interface file name is same .
static NSString *simpleTableIdentifier = #detailTableViewCell ;
detailTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier]
if(cell == nil )
{
NSArray *nib= [[NSBundle mainBundle] loadNibNamed:#"detailTableViewCell" ownder self options:nil];
cell = [nib objectAtIndex:0]
}
return cell ;
}
if(inderPath.Section ==1 )
{
similarly for another subclass of UItableViewCell ;
}
if(inderPath.Section ==2 )
{
similarly for another subclass of UItableViewCell ;
}
// one common cell for other sections
NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
cell.textLabel.text = [arrControls objectAtIndex:indexPath.row];
return cell;
}
try this`-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *cellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(indexPath.section == 0)
{
cell.textLabel.text = [firstArray objectAtIndex:indexPath.row];
}
else if (indexPath.section == 1)
{
cell.textLabel.text = [secondArray objectAtIndex:indexPath.row];
}
else if (indexPath.section == 2)
{
cell.textLabel.text = [thirdArray objectAtIndex:indexPath.row];
}
else if (indexPath.section == 3)
{
cell.textLabel.text = [thirdArray objectAtIndex:indexPath.row];
}
else
{
cell.textLabel.text = [FourthArray objectAtIndex:indexPath.row];
}
return cell;
}

#Dalvik. You need different array for each section. And you already have only one mutableArray.
You can take the array where each object in array will give you array for the rows.
The format of data you can use is as follows
(
{key : Array},
{key : Array},
{key : Array},
{key : Array},
)
or simply
(
(Array),
(Array),
)
inside, numberOfRowsInSection: you can access it using
{
return [[[dataArray objectAtIndex:section]ObjectFoyKey:key]count];
or
return [[dataarray objectAtIndex:section]count];
}
inside, cellFOrRowAtIndexPath: you can access it using
{
array = [[dataArray objectAtIndex:section]ObjectFoyKey:key];
cell.textlabel.text = [array objectAtIndex:indexPath.row];
or
array = [dataArray objectAtIndex:section];
cell.textlabel.text = [array objectAtIndex:indexPath.row];
}
Hope this will help you..
Please elaborate your question a little bit. Its hard to understand what exactly your problem is.
In case you are using xib or storyboard for tableCell use this approach 1:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"MyCellIdentifier";
MyCell *cell = (MyCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:CellIdentifier owner:self options:nil];
cell = (MyCell *)[nib objectAtIndex:0];
}
In case you are not using storyboard for cell try this approach 2:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"MyCellIdentifier";
UITableViewCell *cell = (MyCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
[cell setNeedsDisplay];
}
Hope this will help you..
I assign some custom view to UITableViewCell.accessoryView， but if I scroll the tableView crazy, some accessoryView will disappear in iOS 7, and if I touch the cell, it's accessoryView can appear, I don't know why, because it's correct in iOS 6. This is my code, someone can help me?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [NSString stringWithFormat:#"CELL %d", (int)indexPath.row+1];
NSDictionary * dict = [_dataSource objectAtIndex:indexPath.row];
if ([dict objectForKey:#"switch"])
{
cell.accessoryView = [dict objectForKey:#"switch"];
}
else
{
cell.accessoryView = nil;
}
return cell;
}
When we use ReusableCellWithIdentifier in table view it reuse cells in table, you set cell.accessoryView = nil; it's remove accessory view for all cells in table view with same CellIdentifier try this code, it's solve your problem :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
NSDictionary * dict = [_dataSource objectAtIndex:indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryView = [dict objectForKey:#"switch"];
}
cell.textLabel.text = [NSString stringWithFormat:#"CELL %d", (int)indexPath.row+1];
if ([dict objectForKey:#"switch"])
{
cell.accessoryView.hidden=NO;
}
else
{
cell.accessoryView.hidden=YES;
}
return cell;
}
I pass an array called userArray which stores another array with strings. This is what I have so far but I know it's wrong. Can someone point me in the right direction?
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier];
}
//Set Up Cell
DataSingleton *sharedData = [DataSingleton sharedData];
for (NSArray *array in sharedData.usersArray){
cell.primaryLabel.text = [array objectAtIndex:1];
cell.secondaryLabel.text = [array objectAtIndex:2];
cell.profileImage = [UIImage imageNamed:#"111-user.png"];
return cell;
}
}
cellForRowAtIndexPath is a UITableViewDataSource method, and it asks the data for single cell only. So, you have to remove a loop, and set up a single cell at once, using indexPath.row as an array index in your DataSingleton
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier];
}
//Set Up Cell
DataSingleton *sharedData = [DataSingleton sharedData];
NSArray *array = [sharedData.usersArray objectAtIndex:indexPath.row];
cell.primaryLabel.text = [array objectAtIndex:1];
cell.secondaryLabel.text = [array objectAtIndex:2];
cell.profileImage = [UIImage imageNamed:#"111-user.png"];
return cell;
}
Also, you should implement tableView:numberOfRowsInSection: to return [[[DataSingleton sharedData] usersArray] count]
