How to handle two custom cells in one UITableView with UISegmentedControl Actions? - ios

Question

Hi i am new to iOS and SO also. i am facing a problem in my app to display the two custom cells in one tableview with selection of segmented control.when the user click on the segmented=0,it displays the one custom cell and segmented=1 display the second custom cell.
Here is my code upto now i tried,
-(void)callSegmentSelected
{
value1 = (int)segment.selectedSegmentIndex;
if (segment.selectedSegmentIndex == 0)
{
NSString *urlString = [NSString stringWithFormat:#"http:"url"];
NSString *jsonString = [NSString stringWithFormat:catid];
NSData *myJSONData =[jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:#"POST"];
NSMutableData *body = [NSMutableData data];
[body appendData:[NSData dataWithData:myJSONData]];
[request setHTTPBody:body];
NSError *error;
NSURLResponse *response;
NSData *urlData=[NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error];
NSString *str=[[NSString alloc]initWithData:urlData encoding:NSUTF8StringEncoding];
if(str.length > 0)
{
NSData* data = [str dataUsingEncoding:NSUTF8StringEncoding];
NSError *error;
array =[NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
[myTableView reloadData];
}
else
{
NSLog(#"Error");
}
}
else if (segment.selectedSegmentIndex == 1)
{
}
Here is my tableview Delegate methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return array.count;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (value1 == 0)
{
static NSString *cellId = #"Cell";
Cell1 * cell = (Cell1 *)[myTableView dequeueReusableCellWithIdentifier:cellId];
if (cell == nil)
{
NSArray *myNib;
myNib = [[NSBundle mainBundle]loadNibNamed:#"Cell1" owner:self options:nil];
cell = [myNib lastObject];
}
cell.examLbl.text = [[array objectAtIndex:indexPath.row]objectForKey:#"examtitle"];
myTableView.dataSource = self;
myTableView.delegate = self;
[myTableView reloadData];
return cell;
}
else
{
if (value1 == 1)
{
static NSString * cellIdentifier = #"Cell2";
Cell2 *cell = (ContestRewardCell *)[myTableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
NSArray *myNib;
myNib = [[NSBundle mainBundle]loadNibNamed:#"cell2" owner:self options:nil];
cell =[myNib objectAtIndex:0];
}
cell.titleLbl.text = [[array objectAtIndex:indexPath.row]objectForKey:#"title"];
myTableView.dataSource = self;
myTableView.delegate = self;
[myTableView reloadData];
return cell;
}
}
return nil;
}
In this code there are no errors,i checked with debugging mode data will coming to "cell.examLbl.text",but not displaying the custom cell in tableview.What i did mistake in this Code Please help me any one.
Thanks in advance.
Here is answer for my problem, i am not implemented the this
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (value1 == 0)
{
return 102;
}
else if(value1 == 1)
{
return 193;
}
return 0;
}

you need to first register the cell nib in viewDid load
[YourTableView registerNib:[UINib nibWithNibName:#“YourCellNibName” bundle:nil] forCellReuseIdentifier:#“Identifier”];
then use the cell in cellForRowAtIndexPath
example:
-(void)viewDidLoad
{
[super viewDidLoad];
[TableView registerNib:[UINib nibWithNibName:#“MyTableViewCell” bundle:nil]forCellReuseIdentifier:#"cell"];
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
MyTableViewCell *cell = (MyTableViewCell *)[myTableView dequeueReusableCellWithIdentifier:#"cell”];
cell.labelTitle=#"cell”;
return cell;
}
