Grouped Table view in Iphone - ios

Question

I m using grouped table view in my app. I have 2 sections in table. first section has 3 rows and second section has more than 10 rows .when I scrolled sections it displays rows from section 1 after 5 th row of section second. what should I do.
Here is my code...
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
switch (section) {
case 0:
return 3;
break;
case 1:
return 8;
break;
default:
break;
}
return 5;
}
// Customize the appearance of table view cells.
- (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] autorelease];
}
if (indexPath.section==0)
{
if (indexPath.row==0)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 20)];
[Name setText:#"First Name "];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter First Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
if (indexPath.row==1)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 110, 20)];
[Name setText:#"Middle Name"];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter Middle Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
if (indexPath.row==2)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 20)];
[Name setText:#"Last Name "];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter Last Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
}
if (indexPath.section==1) {
if (indexPath.row==0) {
cell.textLabel.text=#"1";
}
if (indexPath.row==1) {
cell.textLabel.text=#"2";
}
if (indexPath.row==2) {
cell.textLabel.text=#"3";
}
if (indexPath.row==3) {
cell.textLabel.text=#"4";
}
if (indexPath.row==4) {
cell.textLabel.text=#"5";
}
if (indexPath.row==5) {
cell.textLabel.text=#"6";
}
if (indexPath.row==6) {
cell.textLabel.text=#"7";
}
if (indexPath.row==7) {
cell.textLabel.text=#"8";
}
}
return cell;
}

You need 2 Cell identifiers. The problem is that you dequeue cells with the same identifier.
Paste the code and should work fine:D
P.S: I did not resolve your problems with your labels. You alloc them each time you display an cell. That is wrong.
#pragma mark -
#pragma mark Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
NSInteger returnValue = 5;
switch (section) {
case 0:
{
returnValue = 3;
break;
}
case 1:
{
returnValue = 8;
break;
}
default:
break;
}
return returnValue;
}
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifierSection1 = #"Cell1";
static NSString *CellIdentifierSection2 = #"Cell2";
UITableViewCell *cell;
if (indexPath.section==0)
{
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierSection1];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifierSection1] autorelease];
}
if (indexPath.row==0)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 20)];
[Name setText:#"First Name "];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter First Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
if (indexPath.row==1)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 110, 20)];
[Name setText:#"Middle Name"];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter Middle Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
if (indexPath.row==2)
{
UILabel *Name=[[UILabel alloc]initWithFrame:CGRectMake(10, 10, 100, 20)];
[Name setText:#"Last Name "];
[cell.contentView addSubview:Name];
UITextField *textName=[[UITextField alloc]initWithFrame:CGRectMake(140, 10, 150, 20)];
textName.placeholder=#"Enter Last Name";
[textName setBorderStyle:UITextBorderStyleNone];
textName.clearButtonMode = UITextFieldViewModeWhileEditing;
textName.keyboardType=UIKeyboardTypeDefault;
textName.returnKeyType=UIReturnKeyDone;
textName.delegate=self;
[cell.contentView addSubview:textName];
}
}
if (indexPath.section==1) {
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifierSection2];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifierSection2] autorelease];
}
if (indexPath.row==0) {
cell.textLabel.text=#"1";
}
if (indexPath.row==1) {
cell.textLabel.text=#"2";
}
if (indexPath.row==2) {
cell.textLabel.text=#"3";
}
if (indexPath.row==3) {
cell.textLabel.text=#"4";
}
if (indexPath.row==4) {
cell.textLabel.text=#"5";
}
if (indexPath.row==5) {
cell.textLabel.text=#"6";
}
if (indexPath.row==6) {
cell.textLabel.text=#"7";
}
if (indexPath.row==7) {
cell.textLabel.text=#"8";
}
}
return cell;
}
Edit:
You can use different identifier for each type of cell. So if you have 2 types of cell you use 2 identifiers if you have 1 type use one identifier and so on. The identifier is used to dequeue a specific type of cell, if no cell can be reused it will simply alloc a new one.
