Interesting predicament: Data for 'variant' is returned successfully, and for some reason it won't display in my cell's UILabel (the UILabel just appears empty, and yes, it's 'hooked up')? Is my currencyFormatter throwing this off somehow? Should I format this line differently? Help is appreciated.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *PointsTableIdentifier = #"PointsCell";
PointsCell *cell = (PointsCell *)[tableView dequeueReusableCellWithIdentifier:PointsTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"PointsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
BUYProduct *productsbuy = self.products[indexPath.row];
cell.productLabel.text = productsbuy.title;
BUYProduct *productDescription = self.products[indexPath.row];
cell.productDescrip.text = productDescription.htmlDescription;
BUYProduct *pointValues = self.products[indexPath.row];
BUYProductVariant *variant = pointValues.variants.firstObject;
cell.priceLabel.text = [self.currencyFormatter stringFromNumber: variant.price];
NSLog(#"%#", variant.price);
}
return cell;
}

I'm binding json datas. Json send me km (kilometer) format float . like ; km=850.564636
I want put in cell this km data. like 850.56
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *simpleTableIdentifier = #"KmCellTableViewCell";
KmCellTableViewCell *cell = (KmCellTableViewCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSString *system = [[UIDevice currentDevice] model];
if ([system isEqualToString:#"iPhone Simulator"]) {

cell.txtPlate.text = [GetVehicle Plate];
cell.txtKm.text = [NSString stringWithFormat:#"%# km",[GetVehicle km]]; return cell; }
i formatted another class. but not in cell.i have to formatted in cell. like this in -(void)FirstBinding{} method

cell.txtKm.text = [NSString stringWithFormat:#"%# km",[GetVehicle km]]; return cell;}double km = [[vehiclesList objectForKey:#"total_km"] doubleValue];
NSNumberFormatter* nf = [[NSNumberFormatter alloc] init];
nf.positiveFormat = #"#,##0.00";
NSString* s = [nf stringFromNumber: [NSNumber numberWithFloat: km]];
txtKilometer.text = [NSString stringWithFormat:#"%#",s];
I need to use two UITableView in one UITableViewController. And I need to create two custom cell for each UITableView.
Can I possible to make this? please help me.
try this.....used two UITableView in one UIViewController...
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView==self.tableview1)
{
return tableview1RowCount;
}
else if(tableView==self.tableview2)
{
return tableview2RowCount;
}
}
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (tableView==self.tableview1)
{
static NSString *CellIdentifier1 = #"tableview1_cell";
tableview1_cell *cell1 = (tableview1_cell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell1 == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"tableview1_cell" owner:self options:nil];
cell1 = [nib objectAtIndex:0];
}
return cell1;
}
if (tableView==self.tableview2)
{
static NSString *CellIdentifier1 = #"tableview2_cell";
tableview2_cell *cell2 = (tableview2_cell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier1];
if (cell2 == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"tableview2_cell" owner:self options:nil];
cell2 = [nib objectAtIndex:0];
}
return cell2;
}
}
and for the method
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
do same as above....separate tableviews with if condition and give actions to each...whatever u want...
I want to get cell value in tableView by using:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *selectedCell=[tableView cellForRowAtIndexPath:indexPath];
NSLog(#"selected cell: %#", selectedCell);
}
It should be a String but this is what i get in the NSLog:
selected cell: <RewardCategoriesTableViewCell: 0x7ae11290; baseClass = UITableViewCell; frame = (0 92.01; 320 44); autoresize = W; layer = <CALayer: 0x7ae11450>>
And this is my Data Source of Array:
NSArray* data= [[NSArray alloc]initWithObjects:category1, category2, category3, category4, category5, category6, category7, nil];
return data;
This is cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
RewardCategoriesTableViewCell *cell = (RewardCategoriesTableViewCell*)[tableView dequeueReusableCellWithIdentifier:#"RewardCategoriesTableViewCell"];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"RewardCategoriesTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
if(indexPath.section >= [categories count]){
return nil;
}
Categories *category = [categories objectAtIndex:indexPath.section];
NSString *identifier = [NSString stringWithFormat:#"Cell%ld", indexPath.section];
NSLog(#"%#" , identifier);
cell.lblCategory.text = category.CategoryName;
NSLog(#"cell value: %#", cell.lblCategory.text);
return cell;
}
Thanks for helps.
In your way, you get the UITableviewCell or subclass
object,so what you log is right.
If you want to get cell value,you should check your dataSource,in
MVC pattern that is your Model.
For example: you have a array named dataArray as Model,Then you get
value dataArray[indexPath.row]
I am not sure why you set text of cell based on the indexPath.section,so ,I post example code based on the code you post
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Categories *category = [categories objectAtIndex:indexPath.section];
NSString * cellText = category.CategoryName;
}
BTY,I think the right way is let text of cell based on the row
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
RewardCategoriesTableViewCell *cell = (RewardCategoriesTableViewCell*) [tableView dequeueReusableCellWithIdentifier:#"RewardCategoriesTableViewCell"];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"RewardCategoriesTableViewCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
if(indexPath.row>= [categories count]){
return nil;
}
Categories *category = [categories objectAtIndex:indexPath.row];
NSString *identifier = [NSString stringWithFormat:#"Cell%ld", indexPath.row];
NSLog(#"%#" , identifier);
cell.lblCategory.text = category.CategoryName;
NSLog(#"cell value: %#", cell.lblCategory.text);
return cell;
}
Then in:
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Categories *category = [categories objectAtIndex:indexPath.row];
NSString * cellText = category.CategoryName;
}
1. in my method in write code example given below -
(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
static NSString *simpleTableIdentifier2 = #"SimpleTableCell2";
if (indexPath.row== 0) {
SimpleTableCell *cell = nil;
cell=(SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
}
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
if (indexPath.row == 1) {
SimpleTableCell2 *cell2 = nil;
cell2=(SimpleTableCell2 *) [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier2];
}
if (cell2 == nil)
{
NSArray *nib2 = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell2" owner:self options:nil];
cell2 = [nib2 objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = #"detail";// [prepTime objectAtIndex:indexPath.row];
//cell.imageView.image = [UIImage imageNamed:#"creme_brelee.jpg"];
cell2.nameLabel.text = [tableData objectAtIndex:indexPath.row];
return cell;
}
can any one help me am i write correct code becoz it will give an error
the error is use of undeclear identifier cell and cell2
i dont understand what is this error
it gives the error after making cell2 before cell2 it works perfectly
help me
thanks
It is giving the error because you have declared it like this:
if (indexPath.row== 0) {
SimpleTableCell *cell = nil;
cell=(SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
}
and you are using the cell variable outside the local scope of this condition.
Do this:
SimpleTableCell *cell = nil;
if (indexPath.row== 0)
{
cell=(SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
}
Also make sure that you have imported the header SimpleTableCell.h.
Hope that helps!
if (indexPath.row == 1) {
SimpleTableCell2 *cell2 = nil;
cell2=(SimpleTableCell2 *) [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier2];
//This is ok
cell2.nameLabel.text = [tableData objectAtIndex:indexPath.row];
}
//No you cant access outside
cell2.nameLabel.text = [tableData objectAtIndex:indexPath.row];
Here, you have declared cell2 inside the if block. So you can use this variable in this scope only. When you try to access cell2 outside, you will get use of undeclared error.
Undeclared identifier means that you didn't register cell class.
You should do that in viewDidLoad:
-(void)viewDidLoad
{
[self.tableView registerClass:[SimpleTableCell class] forCellReuseIdentifier:#"SimpleTableCell"];
[self.tableView registerClass:[SimpleTableCell2 class] forCellReuseIdentifier:#"SimpleTableCell2"];
}
However, NSStringFromClass approach is better when dealing with cell identifiers:
-(void)viewDidLoad
{
[self.tableView registerClass:NSStringFromClass([SimpleTableCell class]) forCellReuseIdentifier:#"SimpleTableCell"];
[self.tableView registerClass:NSStringFromClass([SimpleTableCell2 class]) forCellReuseIdentifier:#"SimpleTableCell2"];
}
If you didn't register a cell class, dequeueReusableCellWithIdentifier can return nil, as specified in the docs:
This method dequeues an existing cell if one is available or creates a new one
using the class or nib file you previously registered. If no cell is available
for reuse and you did not register a class or nib file, this method returns nil.
Additional note: keep your view controller methods as slim as possibile.
you could try these codes:
- (UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath (NSIndexPath *)indexPath{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
static NSString *simpleTableIdentifier2 = #"SimpleTableCell2";
if (indexPath.row== 0) {
SimpleTableCell *cell = nil;
cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil){
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = #"detail";// [prepTime objectAtIndex:indexPath.row];
//cell.imageView.image = [UIImage imageNamed:#"creme_brelee.jpg"];
return cell;
}
SimpleTableCell2 *cell2 = nil;
if (indexPath.row == 1) {
cell2 = (SimpleTableCell2 *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier2];
if (cell2 == nil){
NSArray *nib2 = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell2" owner:self options:nil];
cell2 = [nib2 objectAtIndex:0];
}
cell2.nameLabel.text = [tableData objectAtIndex:indexPath.row];
}
return cell2;
}
if (indexPath.row== 0) {
SimpleTableCell *cell = nil;
cell=(SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
return cell;
}
if (indexPath.row == 1) {
SimpleTableCell2 *cell2 = nil;
cell2=(SimpleTableCell2 *) [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier2];
if (cell2 == nil)
{
NSArray *nib2 = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell2" owner:self options:nil];
cell2 = [nib2 objectAtIndex:0];
}
return cell2;
}
UITableViewCell *commonCell = [tableView dequeueReusableCellWithIdentifier:#"commonToALL"];
if (commonCell == nil) {
commonCell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"commonToALL"];
}
return commonCell;
Try This. This will create two specific cell for index 0 and 1 while two general Cells for remainder as you have 4 rows.
You'd better check you custom cell's tag in SimpleTableCell.xib
whether the tag is 0
and just one custom cell could work like:
(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = #"detail";// [prepTime objectAtIndex:indexPath.row];
//cell.imageView.image = [UIImage imageNamed:#"creme_brelee.jpg"];
if (indexPath.row == 1) {
[cell.thumbnailImageView.image setHidden:Yes];
[cell.prepTimeLabel.text setHidden:Yes];
}
return cell;
}
This is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"simpleTable";
profileCellViewController *cell = [self.myTable dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"simpleTable" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
//loading data
...
...
...
cell.name.text = name;
cell.time.text = time;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
I know the problem is in the if (cell==nil) part
but really don't know hoe I can solve this...
every time im back to this viewcontroller tab the cells duplicated
