When TableView scroll than value changed - iphone

Question

I have created a table view that display data from array.but now when i scroll table view than my data change unacceptably.
So how can i prevent tableview to refresh every time when scroll and set all the data first time when table view created.
here is my code:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
ExampleAppDataObject* theDataObject = [self theAppDataObject]; // Return the number of sections.
return theDataObject.vendorTableAry.count; //this is return value of array and it will be more than 2 which help to create section
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return 4; // i want only 4 row in each section
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
ExampleAppDataObject* theDataObject = [self theAppDataObject];
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
UITableViewCell * cell = [tableView
dequeueReusableCellWithIdentifier: SimpleTableIdentifier];
if(cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:SimpleTableIdentifier];
/*cell = [[[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:SimpleTableIdentifier] autorelease];
*/
if (indexPath.row==0) {
UILabel * vendorLbl = [[UILabel alloc] initWithFrame:CGRectMake(10, 2, 60, 39)];
[[vendorLbl layer] setCornerRadius:5.0f];
//[vendorLbl setFont:[UIFont fontWithName:#"Helvetica-Bold" size:13.0]];
vendorLbl.backgroundColor = [UIColor clearColor];
[vendorLbl setText:#"vender"];
[cell.contentView addSubview:vendorLbl];
UILabel * columnLbl = [[UILabel alloc] initWithFrame:CGRectMake(80, 2, 10, 39)];
columnLbl.backgroundColor = [UIColor clearColor];
[columnLbl setText:#":"];
[cell.contentView addSubview:columnLbl];
UILabel * vendorValueLbl = [[UILabel alloc] initWithFrame:CGRectMake(98, 2, 195, 39)];
[[vendorValueLbl layer] setCornerRadius:5.0f];
//[vendorLbl setFont:[UIFont fontWithName:#"Helvetica-Bold" size:13.0]];
vendorValueLbl.backgroundColor = [UIColor clearColor];
[vendorValueLbl setText:[theDataObject.vendorTableAry objectAtIndex:indexPath.section]];
[cell.contentView addSubview:vendorValueLbl];
}
if (indexPath.row==1) {
