Multiple UITableview in Single Viewcontroller - ios

Question

I have a viewcontroller in that i want to show 3 tableviews(because the content and the table properties are different). How do i add these delegate methodes for 3 tables in one viewcontroller?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [array1 count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {}
EDIT
So what will i do if i want add a uislider to one table row using custom cell and when i slide the value i want to change the display brightness?
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
if (tableView == _displayThemes) {
return 1;
} else {
return 1;
}
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(tableView==_displayThemes) {
return 1;
} else {
return 5;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
if (tableView == _displayThemes) {
cell.textLabel.text = [displaytheme objectAtIndex:indexPath.row];
return cell;
} else {
cell.textLabel.text = [fontlist objectAtIndex:indexPath.row];
return cell;
}
}
- (IBAction)fontButton:(id)sender {
_fontList = [[UITableView alloc]init];
[self.view addSubview:_fontList];
[UIView animateWithDuration:1.5
delay:0
options: UIViewAnimationOptionTransitionCurlUp
animations:^{
_fontList.fram e= CGRectMake(0,800,320,200);
}
completion:^(BOOL finished){
_fontList.frame = CGRectMake(0,280,320,200);
}];
[_fontList reloadData];
}
- (IBAction)button:(id)sender {
_displayThemes = [[UITableView alloc]init];
[self.view addSubview:_displayThemes];
[UIView animateWithDuration:1.5
delay:0
options: UIViewAnimationOptionTransitionCurlUp
animations:^{
_displayThemes.frame=CGRectMake(0,800,320,200);
}
completion:^(BOOL finished){
_displayThemes.frame=CGRectMake(0,280,320,200);
}];
}

Answer 1

It will be the same as you do it with one table view, but you should check which tableview is currently using.
myTableView1.dataSource = self;
...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if (tableView == myTableView1) {
// your code 1
}
else
if (tableView == myTableView2) {
// your code 2
}
else
if (tableView == myTableView3) {
// your code 3
}
}
Edit:
About brightness:
How to change brightness in iOS 5 app?
And about UISlider it has minimunValue and maximumValue properties.
- (void) sliderChanged:(UISlider*)sender{
UISlider *slider = (UISlider*)sender;
[[UIScreen mainScreen] setBrightness:slider.value];
}
Edit:
slider.tag = 1;
[cell addSubview:slider];
...
// when you need..
indexPath = [NSIndexPath indexPathForRow:myRow inSection:mySecion];
UISlider* slider = (UISlider*) [[self.tableView cellForRowAtIndexPath:indexPath] viewWithTag:1];

Answer 2

You always get a reference and can always check for which tableView delegate or dataSource method is called.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (tableView == self.tableView1)
{
return 1;
}
if (tableView == self.tableView2)
{
return 1;
}
if (tableView == self.tableView3)
{
return 1;
}
}
You don't gain anything by using same identifier for all tables. Use something like:
-(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
if (tableView == self.tableView1)
{
static NSString *CellIdentifier1 = #"cellForTable1";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier1];
}
cell.textLabel.text = [NSString stringWithFormat: #"table1: %d.%d", indexPath.section, indexPath.row];
return cell;
}
if (tableView == self.tableView2)
{
static NSString *CellIdentifier2 = #"cellForTable2";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier2];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];
}
cell.textLabel.text = [NSString stringWithFormat: #"table2: %d.%d", indexPath.section, indexPath.row];
return cell;
}
if (tableView == self.tableView1)
{
static NSString *CellIdentifier3 = #"cellForTable3";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier3];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier3];
}
cell.textLabel.text = [NSString stringWithFormat: #"table3: %d.%d", indexPath.section, indexPath.row];
return cell;
}
}

Answer 3

//add tag in tableView .
myTable1.tag = 200;
myTable2.tag = 201;
myTable3.tag = 202;
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
if (tableView.tag == 200)
{
return 1;
}
if (tableView.tag == 201)
{
return 1;
}
if (tableView.tag == 202)
{
return 1;
}
}

Answer 4

You can manage multiple tableView in a single ViewController by
writing below code inside UItableViewDelegate and UItableViewDatasource.
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if tableView == tableView1
{
// place your code here
}
else if tableView == tableView2 {
// place your code here
}
else {
return 0
}
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
if tableView == tableView1
{
// place your code here
}
else if tableView == tableView2 {
// place your code here
}
else {
return 0
}
}
// You can set a different size of your tableView using below lines of code
if tableView == tableView1{
return 50
}
else{
return 40
}

Answer 5

None of the previous worked for me, I come up with the following solution:
public func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
if((tableView1 != nil) && (tableView == tableView1)) {
return Items1.count
}
else if((tableView2 != nil) && (tableView == tableView2)) {
return Items2.count
}
else if((tableView3 != nil) && (tableView == tableView3)) {
return Items3.count
}
else {
return 0
}
}
