How to load data in two section of table view iPhone - iphone

Question

I have 2 sections within a table view and I have loaded one section from one array and one from another. How can I set cell values for both sections?
I'm using the following code:
Title For Header Section.
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection: (NSInteger)section
{
if(section == 0)
return #" Scheduled Patients ";
else
return #" Walk In Patients ";
}
Rows in Section:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(section==0)
return [resultArray count];
else {
EMRAppDelegate *appDelegate = (EMRAppDelegate *)[[UIApplication sharedApplication] delegate];
return [appDelegate.walkPatients count];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIButton * uploadButton = nil;
static NSString * Identifier = #"Identifier";
UITableViewCell * cell = [table dequeueReusableCellWithIdentifier:Identifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:Identifier] autorelease];
uploadButton = [UIButton buttonWithType:UIButtonTypeCustom];
[uploadButton setFrame:CGRectMake(10, 10, 24, 24)];
[uploadButton setImage:[UIImage imageNamed:#"upload.png"] forState:UIControlStateNormal];
[uploadButton addTarget:self action:#selector(onUploadButtonClick:) forControlEvents:UIControlEventTouchUpInside];
[uploadButton setTag:999];
cell.accessoryView = uploadButton;
}
else {
uploadButton = (UIButton *)cell.accessoryView;
}
EMRAppDelegate *appDelegate = (EMRAppDelegate *)[[UIApplication sharedApplication] delegate];
ObjectData *theCellData =[resultArray objectAtIndex:indexPath.row];
WalkPatient * patient = [ appDelegate.walkPatients objectAtIndex:indexPath.row];
if (indexPath.section == 0)
{
// do coding for cell loading for Scheduled Patients
cell.textLabel.font = [UIFont systemFontOfSize:18];
cell.textLabel.text = [NSString stringWithFormat:#"%# %#", theCellData.firstName, theCellData.lasttName];
if (patient.syncDate != nil) {
UIImageView * checkmark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"right.png"]];
[checkmark setFrame:CGRectMake(12, 0, 12, 12)];
[checkmark setTag:998];
[uploadButton addSubview:checkmark];
[checkmark release];
[uploadButton removeTarget:self action:#selector(onUploadButtonClick:) forControlEvents:UIControlEventTouchUpInside];
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy hh:mm"];
cell.detailTextLabel.font = [UIFont systemFontOfSize:12];
cell.detailTextLabel.text = [NSString stringWithFormat:#"Synched: %#", [dateFormatter stringFromDate:patient.syncDate]];
[dateFormatter release];
}
else {
UIView * checkmark = (UIView *)[uploadButton viewWithTag:998];
if (checkmark != nil) {
[checkmark removeFromSuperview];
}
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
else
{
// do load cells for Walk In Patients.
cell.textLabel.font = [UIFont systemFontOfSize:18];
cell.textLabel.text = [NSString stringWithFormat:#"%# %#", patient.firstName, patient.lastName];
if (patient.syncDate != nil) {
UIImageView * checkmark = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"right.png"]];
[checkmark setFrame:CGRectMake(12, 0, 12, 12)];
[checkmark setTag:998];
[uploadButton addSubview:checkmark];
[checkmark release];
[uploadButton removeTarget:self action:#selector(onUploadButtonClick:) forControlEvents:UIControlEventTouchUpInside];
NSDateFormatter * dateFormatter = [[NSDateFormatter alloc] init];
[dateFormatter setDateFormat:#"dd/MM/yyyy hh:mm"];
cell.detailTextLabel.font = [UIFont systemFontOfSize:12];
cell.detailTextLabel.text = [NSString stringWithFormat:#"Synched: %#", [dateFormatter stringFromDate:patient.syncDate]];
[dateFormatter release];
}
else {
UIView * checkmark = (UIView *)[uploadButton viewWithTag:998];
if (checkmark != nil) {
[checkmark removeFromSuperview];
}
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
}

Answer 1

Its simple. In cellForRowAtIndexPath method also you put one condition to check the section and load data according to them.
if (indexPath.section == 0)
{
// do coding for cell loading for Scheduled Patients
UIButton *btnsection0=[UIButton buttonWithType:UIButtonTypeCustom];
[btnsection0 addTarget:self action:#selector(showProject:) forControlEvents:UIControlEventTouchUpInside];
}
else
{
// do load cells for Walk In Patients.
UIButton *btnsection1=[UIButton buttonWithType:UIButtonTypeCustom];
[btnsection0 addTarget:self action:#selector(showProject:) forControlEvents:UIControlEventTouchUpInside];
}

You've almost got it. The cellForRowAtIndexPath method comes with an indexPath parameter that can give you:
NSInteger row = indexPath.row;
NSInteger section = indexPath.section;
Please, always, always make cellForRowAtIndexPath logic mirror the numberOfRowsInSection logic, so when you get asked for a row count:
return (section==0)? [array0 count] : [array1 count];
... and when you get asked for a cell, and you need the data for that cell
NSInteger row = indexPath.row;
NSInteger section = indexPath.section;
NSArray *arrayForThisSection = (section==0)? array0 : array1;
id elementForThisRow = [arrayForThisSection objectAtIndex:row];
// config the cell with elementForThisRow

From the documentation for UITableViewDataSource:
UITableView declares a category on NSIndexPath that enables you to get the represented row index (row property) and section index (section property),
So you can go indexPath.section and it'll tell you which section the tableview wants to populate.

UIButton *btnsection0=[UIButton buttonWithType:UIButtonTypeCustom];
if (indexPath.section == 0)
{
btnsection0.tag = [NSString stringWithFormat:#"%d%d",indexPath.section,indexPath.row];
}else{
btnsection0.tag = [NSString stringWithFormat:#"%d%d",indexPath.section,indexPath.row];
}
[btnsection0 addTarget:self action:#selector(showProject:) forControlEvents:UIControlEventTouchUpInside];
button event
-(IBAction)showProject:(id)sender{
NSString *s = [NSString stringWithFormat:#"%d%d",indexPath.section,indexPath.row];
int section = [[s substringToIndex:1] intValue];
int row = [[s substringFromIndex:0] intValue];
}
