Can I add cell dynamically in static-cell-UITableView? [duplicate] - ios

This question already has answers here:
UITableView: Handle cell selection in a mixed cell table view static and dynamic cells
(6 answers)
Closed 7 years ago.
I'm using a UITableView to show sth,and the information in section 1,section 2 will not change,but section 3 is dynamic.
Is there any way to show section 1&2 using static cell,but I can write the datasource of section3?

Here you will get as per your requirement.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (section == 0 || section == 1) {
return 1; //However many static cells you want
} else {
return [_yourArray count];
}
}
-(UITableViewCell*)tableView:(UITableView*)tableView cellForRowAtIndexPath:(NSIndexPath*)indexPath
{
if (indexPath.section == 0 || indexPath.section == 1 ) {
NSString *cellIdentifier = #"staticCellType";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.textLabel.text = #"some static content";
return cell;
} else if (indexPath.section == 1){
NSString *cellIdentifier = #"dynamicCellType";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.textLabel.text = [_yourArray objectAtIndex:indexPath.row];
return cell;
}
return nil;
}

You can easily do like this....
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 3; //number of section
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
switch(section){
case 0:
return 1; //static value as per your requirement
break;
case 1:
return 1; //static value as per your requirement
break;
case 2:
return [yourArray count]; //static value as per your requirement
break;
default
return 1;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CELL";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (indexPath.section == 2) {
NSDictionary *dict = [yourArray objectAtIndex:indexPath.row];
}
//If you perform any task for other section then you can write in switch case
return cell;
}

How to append custom tableviewcells to tableview one by one

I have two tableview controllers lets say PopoverElementsListTable ,ElementsViewTable. one tableview will be in popover state when I click on one of the PopoverElementsListTable cell a custom cell has to added to the ElementsViewTable.I'm able to append only one cell when I try to add another cell to ElementsViewTable its getting replaced with previous cell.
#pragma mark - TableView delegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:
(NSInteger)section{
if (tableView == PopoverElementsListTable) {
return [myArray count];
}
else if (tableView == ElementsViewTable) {
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:
(NSIndexPath *)indexPath{
if (tableView == PopoverElementsListTable) {
static NSString *cellId = #"autoaddress";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
cellId];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:
UITableViewCellStyleDefault reuseIdentifier:cellId];
}
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}else {
NSLog(#"_selectedIndex %lu",(unsigned long)_selectedIndex);
if(_selectedIndex == 1){
AutoFillAddressFormElementcell * cell = [tableView dequeueReusableCellWithIdentifier:#"autoAddressCell"];
if (!cell) {
cell = [[AutoFillAddressFormElementcell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"autoAddressCell"];
}
return cell;
}else if(_selectedIndex == 2){
NSLog(#"Test # 123");
AddressSetterFormElementCell * cell = [tableView dequeueReusableCellWithIdentifier:#"setAddressCell"];
if (!cell) {
cell = [[AddressSetterFormElementCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"setAddressCell"];
}
return cell;
}else{
static NSString *cellId = #"autoaddress";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellId];
if (cell == nil) {
cell = [[UITableViewCell alloc]initWithStyle:
UITableViewCellStyleDefault reuseIdentifier:cellId];
}
cell.textLabel.text = #"List";
return cell;
}
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:
(NSIndexPath *)indexPath{
if(tableView == PopoverElementsListTable){
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"Section:%ld Row:%ld selected and its data is %#",
(long)indexPath.section,(long)indexPath.row,cell.textLabel.text);
[_transarentView setHidden:true];
_selectedIndex = indexPath.row + 1;
NSLog(#"number %lu",(unsigned long)_selectedIndex);
[_displayFromElementTableView reloadData];
}
if(tableView == ElementsViewTable){
}
}
I know I'm able to append only one item because of return 1 in numberOfRowsInSection delegate. I tried replacing with another number but what I achieved is all the cells are identical.How can I get the dynamic count here? How to append customcells one by one which are unidentical.
You need to do it by identifying indexpath .
if (indexPath.row == 0) {
Customcell1 *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
}else if (indexPath.row == 1){
Customcell2 *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
}
return cell;
and so on....
You can check the table view too if you want.

custom table cell displaying nil

I'm trying to set the title and display a button in my custom cell object in my second table view controller, but only my first dynamic prototype cell is displaying text.
The first prototype cell is UITableViewCell and the second is the custom object. In my first view controller I implement almost the same exact method and it works completely fine. Not sure where my error could be, the models I use have all their data in them. I have the correct cell identifier in my storyboard, and the connection from custom cell to the UIButton is set.
Thanks in advance.
Method:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CellIdentifier";
static NSString *QuestionSectionIdentifier = #"QuestionSectionCell";
if (indexPath.section == 0)
{
UITableViewCell *cellQuestion = [tableView
dequeueReusableCellWithIdentifier:QuestionSectionIdentifier];
if (cellQuestion == nil) {
cellQuestion = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:QuestionSectionIdentifier];
}
if (indexPath.row == 0) {
cellQuestion.textLabel.text = _headerQuestion.question;
NSLog(#"question here %#", cellQuestion.textLabel.text);
}
return cellQuestion;
}
else
{
MyTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[MyTableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
if (indexPath.section == 1)
{
if (indexPath.row == 0)
{
[cell.firstButton setTitle:_headerQuestion.questionAuthor.fullName forState:UIControlStateNormal];
[cell.firstButton setTag:_headerQuestion.questionAuthor.userID];
[cell.answerLabelField setHidden:YES];
NSLog(#"section 1 %#", cell.firstButton.titleLabel.text);
}
}
else if (indexPath.section == 2)
{
Answer* answer_num = [_headerQuestion.answers objectAtIndex:indexPath.row]; //object at index
[cell.firstButton setTitle:answer_num.answerAuthor.fullName forState:UIControlStateNormal];
[cell.firstButton setTag:answer_num.answerAuthor.userID];
cell.answerLabelField.text = answer_num.answer;
}
return cell;
}
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 3;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (section == 0)
{
return 1;
}
if (section == 1)
{
return 1;
}
else
{
return [_headerQuestion.answers count];
}
}
Make sure you register both reuse identifiers with the tableview using
- (void)registerClass:(Class nullable)cellClass
forCellReuseIdentifier:(NSString * nonnull)identifier
Or registerNib if you have a nib for the cell.

TableView with multiple prototype cells

I had a simple question regarding a table view with 3 different kinds of prototype cells. The first two occur just once while the third occurs 4 times. Now what I'm confused about is how to specify in my cellforRowatindexpath which cell prototype to use for which row. So, I want something like for row 0, use prototype 1, for row 1, use prototype 2, for rows 3,4,5 and 6 use prototype 3. What's the best way to do this? Do i give each prototype an identifier and then use dequeueReusableCellWithIdentifier:CellIdentifier ?
Can you'll provide some sample code?
EDIT:
Still not working. This is the code I have at the moment. ( I only have one case for the switch statment because I just want to test and see if the cell is being generated in the first row or not, but currently table view is blank)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
switch(indexPath.row)
{
case 0: {static NSString *CellIdentifier = #"ACell";
UITableViewCell *cell = [tableView
dequeueReusableCellWithIdentifier:#"ACell"];
if(cell==nil) {
cell=[[UITableViewCell alloc]
initWithStyle:(UITableViewCellStyleDefault) reuseIdentifier:#"ACell"];
}
return cell;
break;
}
}
}
Acell is my identifier for a cell prototype that I created. I
If you are using three prototype then use three identifiers. Because only one identifier will cause problem. And you will get wrong result. So code like this.
if(indexPath.row==0){
// Create first cell
}
if(indexPath.row==1){
// Create second cell
}
else{
// Create all others
}
You can use switch case also here for best performance.
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (cell.tag == 0)
{
return array1.count;
}
else(cell.tag == 1)
{
return array2.count;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier;
NSString *membershipType = [membershipTypeArray objectAtIndex:indexPath.row];
if ([membershipType isEqualToString:#"silver"]||[membershipType isEqualToString:#"gold"])
{
cellIdentifier = #"cell";
}
else if ([membershipType isEqualToString:#"platinum"])
{
cellIdentifier = #"premiumCustomCell";
cell.customCellImageView.image = [cellImageArray objectAtIndex:indexPath.row];
}
cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!cell) {
cell = [[CustomCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.headingLabel.text = [titleArray objectAtIndex:indexPath.row];
}
Here i wrote code like:
#pragma mark == Tableview Datasource
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
NSInteger nRows = 0;
switch (section) {
case 0:
nRows = shipData.count;
break;
case 1:
nRows = dataArray1.count;
break;
default:
break;
}
return nRows;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *cellIdentifier = #"cellIdentifier1";
NSString *cellIdentifier1 = #"cellIdentifier2";
SingleShippingDetailsCell *cell;
switch (indexPath.section) {
case 0:
cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
//Load data in this prototype cell
break;
case 1:
cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier1];
//Load data in this prototype cell
break;
default:
break;
}
return cell;
}

TableView section

I want to design a dynamic table which has 2 sections, first section has 4 cells and second one has 41 cells. I want to program these 2 sections separately but I can only modify one section. how can I modify each section separately. The codes that I wrote so far is like this:
{
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (section == 0)
return 4;
else
return 41;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Questions";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Questions"];
cell.textLabel.text = [NSString stringWithFormat:#"Question %lu", (unsigned long)indexPath.row +1];
return cell;
}
}
The NSIndexPath has both a row property and a section property. From these two properties, you can tell which cell you are currently working on in
<(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
For example:
(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Questions";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Questions"];
if (indexPath.section == 0)
{
cell.textLabel.text = [NSString stringWithFormat:#"1st Group - Question %d", indexPath.row + 1];
}
else
{
cell.textLabel.text = [NSString stringWithFormat:#"2nd Group - Question %d", indexPath.row + 1];
}
return cell;
}

UITableView - assigning arrays to the right sections in a UITableView

I have a UITableView that I have set-up with 2 sections. The code below is showing the same cell text all over the UITableView. My question in short is, how do you assign sections NSArrays?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [toStartPicker dequeueReusableCellWithIdentifier:#"cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
cell.textLabel.text= [nameJan objectAtIndex:indexPath.row];
cell.detailTextLabel.text= [subTitlesJan objectAtIndex:indexPath.row];
UITableViewCell *cellTwo = [toStartPicker dequeueReusableCellWithIdentifier:#"cellTwo"];
if (cellTwo == nil) {
cellTwo = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cellTwo"];
}
cellTwo.textLabel.text= [nameFeb objectAtIndex:indexPath.row];
cellTwo.detailTextLabel.text= [subTitlesFeb objectAtIndex:indexPath.row];
return cell;
}
Make the method like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [toStartPicker dequeueReusableCellWithIdentifier:#"cell"];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
if( indexPath.section == 0 )
{
cell.textLabel.text= [nameJan objectAtIndex:indexPath.row];
cell.detailTextLabel.text= [subTitlesJan objectAtIndex:indexPath.row];
}
else
{
cell.textLabel.text= [nameFeb objectAtIndex:indexPath.row];
cell.detailTextLabel.text= [subTitlesFeb objectAtIndex:indexPath.row];
}
return cell;
}
Also, make sure the following methods look like this
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 2;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
if( 0 == section )
{
return [nameJan count];
}
else
{
return [nameFeb count];
}
}
