I try to add some text taken from a textfield and an image taken from photo album to UITableViewCell.
In one UIViewController I have a UITextField and a UIImageView. This is the code I use to
populate an array of products that I would present in cells of a UITableView.
Article *article1 = [[Article alloc] initWithTitle: #"First Text" Subtitle: #"Data&Time" Thumbnail: [UIImage imageNamed: #"image.png"]];
articles = [[NSMutableArray alloc] init];
[articles addObject:article1];
Do you want the cells to display the properties of your Article objects? Let's assume you only have one section and your UITableViewController already has a reference to an array of Articles called "articles".
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
Article *article = [articles objectAtIndex:indexPath.row];
cell.textLabel.text = article.title;
cell.detailTextLAbel.text = article.subtitle;
cell.imageView.image = article.thumbnail;
return cell;
}
You have to inherit UICell class, there are too many examples. Just google smth like "custom UITableView" or "custom UITableViewCell".
Also, there is left image for cell in Cocoa.
ADD a custom cell to display image to the table view
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"MoreDetailCell";
MoreDetailCell *cell = (MoreDetailCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"MoreDetailCell" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (MoreDetailCell *)currentObject;
break;
}
}
}
cell.compImage.image = [UIImage imageNamed:#"Placeholder.png"];
cell.yourtexfieldname.text = #"ABC";
}

I am new to iphone. my cutomcell label value is disappearing when I scroll the table view.
Again it appears when I click on that cell.
Can anyone help me?
Thanks in Advance.
//table view in view controller created in xib
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ListOfProductsCell";
ListOfProductsCell *cell = (ListOfProductsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
NSArray *nib =[[NSBundle mainBundle] loadNibNamed:#"ListOfProductsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
productItemDit=[productListArry objectAtIndex:indexPath.row];
NSString *offerStr= [NSString stringWithFormat:#"%.2f",[[productItemDit objectForKey:#"offer"] floatValue]];
NSString *fullCostStr=[[currencyCodeStr stringByAppendingString:#" "] stringByAppendingString:offerStr];
NSLog(#"%#",fullCostStr);
cell.itemCostLbl.text=fullCostStr;
} else {
cell.itemStepper = (UIStepper *) [cell viewWithTag:2];
cell.itemAddedLbl =(UILabel*)[cell viewWithTag:1];
}
if (tableView == self.searchDisplayProduct.searchResultsTableView) {
searchProductItemDit=[searchProductListArry objectAtIndex:indexPath.row];
NSLog(#"searchdit:%#",searchProductItemDit);
cell.itemNameLbl.text= [searchProductItemDit objectForKey:#"name"];
self.searchDisplayProduct.searchResultsTableView.separatorColor=[UIColor colorWithRed:200.0 green:0.0 blue:0.0 alpha:1.0];
} else {
productItemDit=[productListArry objectAtIndex:indexPath.row];
NSLog(#"dit:%#",productItemDit);
cell.itemNameLbl.text=[productItemDit objectForKey:#"name"];
}
cell.itemAddedLbl.text = [[NSString alloc] initWithFormat:#"%d",itemCount];
cell.itemImg.image = [UIImage imageNamed:#"profp.jpg"];
return cell;
}
Solved by doing like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ListOfProductsCell";
ListOfProductsCell *cell = (ListOfProductsCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
NSArray *nib =[[NSBundle mainBundle] loadNibNamed:#"ListOfProductsCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
} else {
cell.itemStepper = (UIStepper *) [cell viewWithTag:2];
cell.itemAddedLbl =(UILabel*)[cell viewWithTag:1];
}
if (tableView == self.searchDisplayProduct.searchResultsTableView) {
cell.itemNameLbl.text= [[searchProductListArry objectAtIndex:indexPath.row] objectForKey:#"name"];
} else {
cell.itemNameLbl.text=[[productListArry objectAtIndex:indexPath.row] objectForKey:#"name"];
}
cell.itemCostLbl.text=[NSString stringWithFormat:#"%# %.2f", currencyCodeStr , [[[productListArry objectAtIndex:indexPath.row] objectForKey:#"offer"] floatValue]];
cell.itemAddedLbl.text = [[NSString alloc] initWithFormat:#"%d",itemCount];
cell.itemImg.image = [UIImage imageNamed:#"profp.jpg"];
return cell;
}
As you haven't post much of the information this is my guess.when you scroll table view it internally calls the reloadData method . You need to use reuse Identifier to preserve the state of the cell. You can initialize the cell in cellForRowAtIndexPath like :
static NSString *cellIdentifier = #"cellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
// or cell initializing logic here for the custom cell
}
in case of custom cell add reuse identifier in the xib and use it in your cellForRowAtIndexPath method
In my UITableViewCells I need to download different image for each cell, what should I do for such kind of problem...
You should use that method still, and then configure each cell independently. Just make sure your cell setup isn't on your construction block
UITableViewCell *cell = [tableView dequeue..];
if (!cell) {
cell = ...;
}
cell.image = ...;
item will be your dictionary of images
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"MyIdentifier"];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"MyIdentifier"]];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
NSDictionary *item = (NSDictionary *)[self.content objectAtIndex:indexPath.row];
cell.textLabel.text = [item objectForKey:#"mainTitleKey"];
cell.detailTextLabel.text = [item objectForKey:#"secondaryTitleKey"];
NSString *path = [[NSBundle mainBundle] pathForResource:[item objectForKey:#"imageKey"] ofType:#"png"];
UIImage *theImage = [UIImage imageWithContentsOfFile:path];
cell.imageView.image = theImage;
return cell;
}
Well basically I am trying to pass a string to a uiwebview that just so happens to be in html format, however I am passing it to the uiwebview using loadHTMLString:myHTML.
the problem that I am having is that I cannot see any text at all. I have set up a custom view which I have then deleted the view, added a uitableviewcell then inside the cell I have added a uiwebview. I have then set the related class to the class in which I would like to display the tableviewcell, then linked my getter/setter to the tableviewcell and the uiwebview inside the tableviewcell..
Then this is the code that follows with me trying to set the richtext of the uiwebview.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (indexPath.section == 0) {
if (indexPath.row == 0) {
// Set cell height
[self tableView:tableView heightForRowAtIndexPath:indexPath];
// Configure the cell using custom cell
[[NSBundle mainBundle] loadNibNamed:#"SearchCellHtml" owner:self options:nil];
cell = searchCellHtml;
// pass in some data into myHTML
myUIWebView = [[UIWebView alloc] init];
NSString *myHTML = #"<html><body><h1>Hello, world!</h1></body></html>";
[myUIWebView loadHTMLString:myHTML baseURL:nil];
//Disclosure Indicator
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
any help with this would be greatly appreciated.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (indexPath.section == 0) {
if (indexPath.row == 0) {
[self tableView:tableView heightForRowAtIndexPath:indexPath];
// load the cell ?
cell = [[NSBundle mainBundle] loadNibNamed:#"SearchCellHtml" owner:self options:nil];
myUIWebView = [[[UIWebView alloc] init] autorelease]; // autorelease
NSString *myHTML = #"<html><body><h1>Hello, world!</h1></body></html>";
[myUIWebView loadHTMLString:myHTML baseURL:nil];
//add webView to your cell
myUIWebView.frame = cell.bounds;
[cell addSubview:myUIWebView];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;

i building an chat app and i have a little problem, build cellforrowatindexpath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"UserCell";
UserCell *cell = (UserCell *)
[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (nil == cell) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"UserCell"
owner:nil
options:nil];
for (id currentObject in topLevelObjects) {
if ([currentObject isKindOfClass:[UITableViewCell class]]) {
cell = (UserCell *) currentObject;
break;
}
}
}
NSString *nameValue = [self.names objectAtIndex:indexPath.row];
NSString *statusValue = [self.usersStatus objectAtIndex:indexPath.row];
cell.name.text = nameValue;
cell.status.text = statusValue;
return cell;
}
and in every cell i have a label what is hidden,and in:
-(void)chatHandlerNewMsg:(ChatHandler*)chat withInt:(NSString*)userId{
NSInteger tmp = [self.usersID indexOfObject:userId];
NSIndexPath *index = [NSIndexPath indexPathForRow:tmp inSection:0];
UserCell *cell = (UserCell*)[self.table cellForRowAtIndexPath:index];
[cell.newMsg setHidden:NO];
[self.table reloadData];
}
i check for new msg and if so i bring the uilabel from hidden to shown.
the problem is that the table view show this uilabel(that it is hidden by default) in other cells in the table view and not only in the specific one that we choose in :
UserCell *cell = (UserCell*)[self.table cellForRowAtIndexPath:index];
When ever you dequeue a cell you need to manually reset any state that a previous row may have set.
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell) {
//Reset cell state (make label hidden)
}
else
{
//Create new cell and configure (hide labels)
}
//Set any common attributes here (title)
return cell;
I try to make a custom cell with a Uilabel and textfield
And i get this:
-> http://data.imagup.com/9/1119535256.png
But it's not given given my value ("Titre" & "Valeur" are generic):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"InscriptionCustomCell";
InscriptionCustomCell *cell = (InscriptionCustomCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *topLevelObjects = [[NSBundle mainBundle] loadNibNamed:#"InscriptionCustomCell" owner:self options:nil];
for (id currentObject in topLevelObjects){
if ([currentObject isKindOfClass:[UITableViewCell class]]){
cell = (InscriptionCustomCell *) currentObject;
break;
}
}
}
cell.selectionStyle = UITableViewCellSelectionStyleNone;
if(indexPath.section ==0)
{
[cell.titreCell setText:[model.listModuleInfoPerso objectAtIndex:indexPath.row]];
[cell.contenuCell setPlaceholder:[model.listModuleInfoPerso objectAtIndex:indexPath.row]];
}else {
[cell.titreCell setText:[model.listModuleInfoSupp objectAtIndex:indexPath.row]];
[cell.contenuCell setPlaceholder:[model.listModuleInfoSupp objectAtIndex:indexPath.row]];
}
return cell;
}
No error :S, an idea?
Put an NSLog in the [model.listModuleInfoPerso objectAtIndex:indexPath.row] so you can see what is coming out...
You probably forgot to hook up the label and the text field from Interface Builder to the properties in your InscriptionCustomCell subclass.
Here it seems that you haven't set the delegate for UITextField. So, please set delegate now and then you can access the TextField entry.
