Randomly Grouping TableView data in xcode - ios

Question

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;
}

Answer 1

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;
}

Answer 2

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;
}

Answer 3

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..
