-(void)viewDidLoad
{
[super viewDidLoad];
arryData = [[NSArray alloc] initWithObjects:#"MCA",#"MBA",#"BTech",#"MTech",nil];
arryData2 = [[NSArray alloc] initWithObjects:#"Objective C",#"C++",#"C#",#".net",nil];
flag=1;
myTable1.hidden=YES;
myTable2.hidden=YES;
btnOne.layer.cornerRadius=8;
btnTwo.layer.cornerRadius=8;
myTable1.layer.cornerRadius=8;
myTable2.layer.cornerRadius=8;
myTable1.delegate=self;
myTable1.dataSource=self;
myTable2.delegate=self;
myTable2.dataSource=self;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(self.myTable1=tableView)
{
return [arryData count];
}
else {
return [arryData2 count];
}
}
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 20;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView==self.myTable1)
{
static NSString *CellIdentifier1 = #"Cell1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1] ;
}
cell.textLabel.text = [arryData objectAtIndex:indexPath.row];
NSLog(#"1here is%i %#",indexPath.row,cell.textLabel.text);
return cell;
}
else
{
static NSString *CellIdentifier2 = #"Cell2";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2] ;
}
cell.textLabel.text = [arryData2 objectAtIndex:indexPath.row];
return cell;
}
}
-(IBAction)btnCategory:(id)sender
{
if (flag==1) {
flag=0;
myTable1.hidden=NO;
myTable2.hidden=YES;
}
else{
flag=1;
myTable1.hidden=YES;
myTable2.hidden=YES;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
myTable1.hidden=YES;
myTable2.hidden=YES;
}
-(IBAction)btnTopic:(id)sender
{
if (flag==1) {
flag=0;
myTable2.hidden=NO;
myTable1.hidden=YES;
}
else{
flag=1;
myTable2.hidden=YES;
myTable1.hidden=YES;
}
}
</code>
when i remove datasource of mytable2 all data gets added to table1 else nothing gets loaded in none of the table.

Answer 1

You did mistake. See my code..
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(self.myTable1==tableView) // ----- Change here you need to write == symbol instead of = symbol
{
return [arryData count];
} else {
return [arryData2 count];
}
}

Try this,
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if(tableView==myTable1)
{
return [arryData count];
}
else {
return [arryData2 count];
}
}
-(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] ;
}
if(myTable1==tableView)
{
cell.textLabel.text = [arryData objectAtIndex:indexPath.row];
NSLog(#"1here is%i %#",indexPath.row,cell.textLabel.text);
}
else
{
cell.textLabel.text = [arryData2 objectAtIndex:indexPath.row];
}
return cell;
}
