I have a UITableView that serves as a menu (user picks a row and fires a segue). Currently my code looks like:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if ([self isAuthorized]) {
if ([self isAdmin]) {
return 7;
}
return 5;
} else {
return 4;
}
}
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
if ([self isAuthorized]) {
if ([self isAdmin]) {
if (indexPath.row == 0) {
// code 1
} else (indexPath.row == 1) { {
// code 2
} // etc...
} else {
if (indexPath.row == 0) {
// code 1
} else (indexPath.row == 1) { {
// code 2
} // etc...
}
} else {
if (indexPath.row == 0) {
// code 1
} else (indexPath.row == 1) { {
// code 2
} // etc...
}
}
is it possible to tie action initiated by cell with a cell, so didSelectRowAtIndexPath looks simplier?
You could create your custom UITableViewCell classes and try doing the following:
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
id cell = [tableView cellForRowAtIndexPath: indexPath];
if ([cell isKindOfClass: [AdminCellClass class]])
{
//code here
}
else if
...
}

I have two section in UITableviewCell. I want hide that two section.
this is my code.
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
if (section == 0)
{
return CGFLOAT_MIN;
}
else
{
return 32.0f;
}
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [storename2 count];
}
- (NSString *)tableView:(UITableView *)tableViewtitleForHeaderInSection:(NSInteger)section
{
if (section == 0)
{
return nil;
}
else
{
return [storename2 objectAtIndex:section];
}
}
In Viewdidload.
- (void)viewDidLoad
{
[super viewDidLoad];
self->CartTableview.contentInset = UIEdgeInsetsMake(-1.0f, 0.0f, 0.0f, 0.0);
}
But its only Hide First Section,
show below image i want like this (When Card Is Empty Hide Sections and when i add products to the card show all(two)section.)
help me,
show 1st image.
when i add product to card two section will show and when i remove the product all section will hidden.
Thanks in Advance.
Just return 0 in heightForHeaderInSection tableview delegate method...
- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
// Specific section
if (section == 0)
return 0.0f;
// all sections
return 0;
}
I think you need change in bellow method
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section
{
return CGFLOAT_MIN;
}
And Remove this method
- (NSString *)tableView:(UITableView *)tableViewtitleForHeaderInSection:(NSInteger)section
{
if (section == 0)
{
return nil;
}
else
{
return [storename2 objectAtIndex:section];
}
}
This will hide all the section header in your tableview.
Also don't forget to set UITableview Delegate & datasource.
- (void) viewDidLoad {
[super viewDidLoad];
self.tableView.contentInset = UIEdgeInsetsMake(-1.0f, 0.0f, 0.0f, 0.0);
}
- (CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
// Specific section
if (section == 0)
return 0.0f;
// all sections
return 0;
}
- (NSString*) tableView:(UITableView *) tableView titleForHeaderInSection:(NSInteger)section
{ // Specific section
if (section == 0) {
return nil;
} else {
// all sections
// return some string here ...
return nil;
}
}
Use switch-case to handle multiple section height.
func tableView(_ tableView: UITableView, heightForHeaderInSection section: Int) -> CGFloat {
let headerHeight: CGFloat
switch section {
case 0:
// first section for test - set value for height
headerHeight = 0
default:
// other Sections - set value for height
headerHeight = 0
}
return headerHeight
}

You can handle tap on UITableViewCell the same as you implement in cellForRowAtIndexPath method
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSDictionary *dict = dataArray[indexPath.row];
UITableViewCell *cell = [tableView cellForRowAtIndexPath: indexPath];
if([dict[#"type"] isEqual:#"Traffic" ]){
//Find your collectionView in cell
//Tap on Traffic cells
}
else if([dict[#"type"] isEqual:#"News"]){
//Tap on News cells
}
else {
//Tap on other cells
}
}
And in cellForRowAtIndexPath you need
TrafficCell.collectionView.delegate = self;
CategoryCell.CategorycollectionView.delegate = self;
for handle tap on UICollectionViewCell and implement UICollectionViewDelegate method
- (void)collectionView:(UICollectionView *)collectionView didSelectItemAtIndexPath:(NSIndexPath *)indexPath {
//Tapped on your collectionViewCell inside the uitableviewcell
}
I have code
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == 9) {
height = 124.0f;
}
return height;
}
but cellForRowAtIndexPath returns 44.0f for indexPath.row == 9
Why is not returning 124?
Hear is just the idea what i am thinking to implement this,
I want to implement book like pages, for this i want to take UITableView and rotated-90 degree and its cell by 90 degree, and now i want to subclass UITableViewCell, now within this tableview cell it is possible to add UITableview so that user can scroll vertically to see the contents and user can also scroll horizontally to go to next cell of rotated tableview.
It is just i am thinking, is there any better way to implement this.
yes it is possible, I added the UITableVIew within the UITableView cell
.. :)
no need to add tableview cell in xib file - just subclass the UITableviewCell and use the code below, a cell will be created programatically.

Swift version
Create a single view project add tableview inside storyboard and set up its datasource and delegate
Paste code below to ViewController.swift
import UIKit
class ViewController: UIViewController,UITableViewDataSource,UITableViewDelegate {
override func viewDidLoad() {
super.viewDidLoad()
// Do any additional setup after loading the view, typically from a nib.
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()

var cell:CustomCell? = tableView.dequeueReusableCellWithIdentifier("Cell") as? CustomCell
if cell == nil {
cell = CustomCell(style: UITableViewCellStyle.Default, reuseIdentifier: "Cell")

return cell!
}
func tableView(tableView: UITableView, heightForRowAtIndexPath indexPath: NSIndexPath) -> CGFloat {

}
create a new file CustomCell.swift which is the subclass of UITableViewCell and do not select with xib this file is without .xib file table and its cell will be created programatically as in objective-c code.
Paste code below to CustomCell.swift

Better way: use a UIPageViewController for your left/right page scrolling. Each page can contain a table view.
Although rob's Idea is better but yes it is possible. Check how:
Take 2 table view, give them tag 1, 2, let's call these kTagBaseTableView, kTagInnerTableView. Now below is the blue print, how to deat with two table view, with delegate and data source attached to single view controller.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView{ // Default is 1 if not implemented
switch (tableView.tag) {
case kTagBaseTableView:
return baseSectionCount;
break;
case kTagInnerTableView:
return innerSectionCount;
break;
default:
break;
}
return 0;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
switch (tableView.tag) {
case kTagBaseTableView:
return [baseDataSource count];
break;
case kTagInnerTableView:
return [innerDataSource count];
break;
default:
break;
}
return 0;
}
// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = nil;
switch (tableView.tag) {
case kTagBaseTableView:{
static NSString* baseIdentifier = #"baseTableViewCell";
cell = [tableView dequeueReusableCellWithIdentifier:genderIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:genderIdentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}
cell.textLabel.text = NSLocalizedString(titleKey, nil);
return cell;
}
break;
case kTagInnerTableView:{
static NSString* innerIdentifier = #"innerTableViewCell";
cell = [tableView dequeueReusableCellWithIdentifier:genderIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:genderIdentifier];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
}
cell.textLabel.text = NSLocalizedString(titleKey, nil);
return cell;
}
default:
break;
}
return cell;
}
- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section{ // fixed font style. use custom view (UILabel) if you want something different
switch (tableView.tag) {
case kTagBaseTableView:
break;
case kTagInnerTableView:
break;
default:
break;
}
return nil;
}
//TABLE VIEW DELEGATE
- (void) tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{

break;

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);
}];

}
completion:^(BOOL finished){
_displayThemes.frame=CGRectMake(0,280,320,200);
}];
}
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];
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;
}
}
//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;

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
}
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
}
}
