Adding a third label to a cell? - iphone

As title says I would like to have 3 labels in my cell (in tableView). As can be seen in the code below I currently only have 2 labels which are name, as textLabel and book as detailTextLabel. But what if I also would like chapter as a label (own row in the tabelView cell)? What would be the best way to implement this?
The output should look like this in the tableView:
Name
Book
Chapter
/Thanks in regards!
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"BookmarkCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Bookmark *item = [self.items objectAtIndex:indexPath.row];
NSArray *chunks = [item.name componentsSeparatedByString: #","];
NSString *name;
NSString *book;
NSString *chapter;
if ([chunks count] > 0)
{
name = [chunks objectAtIndex:0];
if ([chunks count] > 1)
{
book = [chunks objectAtIndex:1];
if ([chunks count] > 2)
{
chapter = [chunks objectAtIndex:2];
}
}
}
cell.textLabel.text = name;
cell.detailTextLabel.text = book;

Sounds like your going to want a custom UITableViewCell and with that you can add anything you would like into it. From there just name the labels that you put into it and write the code accordingly to fill them with the cellForRowAtIndexPath method.

Create a custom UIView and add it as a subview to the cell's contentView. In this custom view add as many UILalels as you would like. You don't actually have to create a custom view to do this, but it allows for greater versatility.
Here is some basic code to achieve three labels.
UIView * pNewContentView= [[UIView alloc] initWithFrame:cell.contentView.bounds];
CGRect labelFrame= pNewContentView.bounds;
labelFrame.size.width= labelFrame.size.width * 0.33;
UILabel* pLabel1=[[UILabel alloc] initWithFrame:labelFrame];
[pNewContentView addSubview:pLabel1];
labelFrame.origin.x= labelFrame.size.width;
UILabel* pLabel2=[[UILabel alloc] initWithFrame:labelFrame];
[pNewContentView addSubview:pLabel2];
labelFrame.origin.x= labelFrame.origin.x + labelFrame.size.width;
UILabel* pLabel3=[[UILabel alloc] initWithFrame:labelFrame];
[pNewContentView addSubview:pLabel3];
[cell.contentView addSubview:pNewContentView];

If what you need is simply another label, then you can do what mark says, create a subview and set it to your cell.
If you want to have something can do more, what you need is a custom UITableViewCell. You can define buttons and other controls. Take a look at this document apple provide. This document can really help to understand how UITableViewCell works so it's worth reading.

Custom UITableViewCell does not show the labels in storyboard

In this screen shot you can see that I have added UITableView in UIViewController then customized the UITableViewCell by adding some labels in it. But the issue is when I run the application. All of the cells are empty. There are no labels at all.
I am not getting what can be the issue. I have searched the web and read tutorials but couldn't resolve it.
I resolved this issue by myself, just after little effort.
Actually when you create a custom cell you have to do these things:
Setup the labels, images etc on storyboard cell.
Create a custom cell class (inheriting from UITableViewCell)(CustomCell.h & .m), CustomCell.h having all of the properties as iboutlet for labels, images etc. and synthesize them all in implementation.
After creating this custom class go back to storyboard, select the custom cell, change its class to the CustomCell and give it some identifier like "MyCustomCell", then right click on the custom cell and connect the IBOutlets with labels etc.
Now import CustomCell class in the class where you are implementing the UITableView and use the properties you defined in CustomCell class.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"MyCustomCell";
CustomCell*cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier] autorelease];
}
// Here we use the provided setImageWithURL: method to load the web image
// Ensure you use a placeholder image otherwise cells will be initialized with no image
[cell.imageView setImageWithURL:[NSURL URLWithString:#"http://example.com/image.jpg"]
placeholderImage:[UIImage imageNamed:#"placeholder"]];
cell.myCustomLabel.text = #"My Text";
return cell;
}
I did this all and my issue was resolved and please don't forget to connect the delegates & datasource and table.
Hope this will help others.
It is little bit late but you can solve your problem by setting the background color of your view as Clear Color from your storyboard.
in the tableview's delegate method , cellforrowatindexpath has a uitableviewcell inside it , there should be an identifier in the initialization of this cell. possibly it is "cell" or "cellIdentifier" .
you just need to select your cell from storyboard and enter this identifier string to the storyboard , where uitableviewcell's attribute inspector stays.
hope this helps.. :)
First Set cell identifier in storyboard #"Cell"
then set tag of label
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
// Create
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] ;
}
UILabel *lblDate = (UILabel*)[cell viewWithTag:101];
UILabel *lblDistance = (UILabel*)[cell viewWithTag:102];
UILabel *lbltype = (UILabel*)[cell viewWithTag:103];
lblDate.text = [temp objectAtIndex:indexPath.row] valueForKey:#"date"] stringByReplacingOccurrencesOfString:#"-" withString:#"/"]];
lblDistance.text = [NSString stringWithFormat:#"%# KM",[[temp objectAtIndex:indexPath.row] valueForKey:#"distance"]];
NSString *type = [NSString stringWithFormat:#"%#",[[temp objectAtIndex:indexPath.row] valueForKey:#"distance"]];
if([type isEqualToString:#"0"])
{
lbltype.text = #"Personal";
}
else
{
lbltype.text = #"Bussiness";
}
// Configure
return cell;
}

iphone - UITableView scroll problem

I have created a TableView in my application with 5 sections in it.
Sections 1 - 4 only contain one row each for the minute and section 5 contains 5 rows.
Everything works fine until I scroll the TableView off the screen. In my first section and row (cell) I have the accessoryView set to a UILabel with some text in it.
Every other cell has the disclosure button as the accessoryType.
When I scroll the tableView the text I have in the first cell somehow appears in the the last cell!?
I have set up my data by adding NSStrings to array's and then adding them as dictionaries to an NSMutableArray.
And here is my cell set up:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
// UISwitch *aUISwitch = [[[UISwitch alloc]initWithFrame:CGRectZero]autorelease];
// Configure the cell.
NSDictionary *dictionary = [listOfSettings objectAtIndex:indexPath.section];
NSArray *array = [dictionary objectForKey:#"Settings"];
NSString *cellValue = [array objectAtIndex:indexPath.row];
cell.textLabel.text = cellValue;
if([cellValue isEqualToString:#"Status"]){
UILabel *viewLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 100, 20)];
[viewLabel setText:#"Connected"];
cell.accessoryView = viewLabel;
[viewLabel release];
}
else{
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
}
return cell;
}
I know cells get deleted/removed when they go off screen so I presume this has something to do with it? What is the recommended practice for dealing with cells that go off screen and reappear?
just at quick glance... in the else statement, not only do you need to set the cell.accessoryType, but also set the cell.accessoryView=nil;
the accesoryView is still there as the cell was recycled.

Customized UITableViewCell

How can i customize a UITableviewCell, as i want to see a label, date and picture in a single cell.
There are two options (may be more). You could use the native UITableViewCell properties to add content to the cell, or create a custom cell (by that I mean, add your own subviews to the Cell). To get started try the first one, it is simple elegant and the results will be quite good. For example try the following cell creation method:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
// notice the Style. The UITableViewCell has a few very good styles that make your cells look very good with little effort
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell...
// In my case I get the data from the elements array that has a bunch on dictionaries
NSDictionary *d = [elements objectAtIndex:indexPath.row];
// the textLabel is the main label
cell.textLabel.text = [d objectForKey:#"title"];
// the detailTextLabel is the subtitle
cell.detailTextLabel.text = [d objectForKey:#"date"];
// Set the image on the cell. In this case I load an image from the bundle
cell.imageView.image = [UIImage imageNamed:#"fsaint.png"];
return cell;
}
You can customize UITableViewCell using either Interface Builder or through Code
Have a look at this link.
There you'll find how to make a custom cell with Interface Builder and use it in XCode for your application.
http://www.e-string.com/content/custom-uitableviewcells-interface-builder
I'm a big fan of overriding the UITableViewCell class, and doing custom drawing in self.contentView. This technique is a little more complicated, but it leads to much better scrolling performance.
For example, lets say you override your cell, and have 3 properties on it like so:
#property(nonatomic, retain) UIImage *userPic;
#property(nonatomic, retain) NSString *label;
#property(nonatomic, retain) NSString *date;
Then you can draw them in the cell using the (drawRect:) function:
- (void)drawRect:(CGRect)rect {
[super drawRect:rect];
[userPic drawInRect: CGRectMake(10, 5, 50, 50)];
[label drawAtPoint:CGPointMake(70, 5) withFont:[UIFont boldSystemFontOfSize:17]];
[date drawAtPoint:CGPointMake(70, 30) withFont:[UIFont systemFontOfSize:14]];
}
For more examples try checking out this framework that uses this style: https://github.com/andrewzimmer906/XCell

UIButton in UITableViewCell events not working

I see this problem all over the net, and none of the solutions listed work for me!
I have added UIButton to a UITableViewCell in IB. I have assigned a custom UITableViewCell class to the UITableViewCell. My custom UITableViewCell class has an IBAction that im connecting to the Touch Up Inside event (I have tried other events they all don't work) but the IBAction function is never called!
There is nothing else in the UITableViewCell, I have added the UIButton directly into the Content View. And everything has user interaction enabled! It is as simple as that I have nothing complex going on!
What is is about a UITableViewCell that stops buttons working?
EDIT: By request the code where I initialize my UITableViewCells the custom class is called DownloadCell
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"DownloadCell";
DownloadCell *cell = (DownloadCell *)[aTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
UIViewController * cellController = [[UIViewController alloc] initWithNibName:#"DownloadCell" bundle:nil];
cell = (DownloadCell *)cellController.view;
[cellController release];
}
SoundLibrarianIPhoneAppDelegate * del = (SoundLibrarianIPhoneAppDelegate *)[UIApplication sharedApplication].delegate;
DownloadQueue * dq = del.downloadQueue;
DownloadJob * job = [dq getDownloadJob: indexPath.row];
[job setDelegate:self];
SoundInfo * info = [job sound];
NSArray * seperated = [info.fileName componentsSeparatedByString: #"."];
NSString * displayName = [seperated objectAtIndex:0];
displayName = [displayName stringByReplacingOccurrencesOfString:#"_" withString:#" "];
displayName = [displayName capitalizedString];
[cell.titleLabel setText: displayName];
cell.progressBar.progress = job.percentCompleted;
[cell.progressLabel setText: [job getProgessText]];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.userInteractionEnabled = YES;
[cell setDelegate:self];
return cell;
}
Seems the problem was to do with me updating the table cells too often, so this was interrupting any interaction with the cells themselves
have U placed this code int the table view.?
tableView.delegate=self;
tableView.dataSource=self;
Thanks,

How to display multiple columns in a UITableView?

I want to display multiple columns in a UITableView.
For Example:
TableView
FName LName Age
----- ----- ---
Abby Michale 34
I think the correct way of doing this is UICollectionView. Started with UITableView and finally failed at some point due to unexpected behavior while trying to implement scrolling both left-right and up-down.
Please check this awesome post for a complete and up-to-date solution:
http://www.brightec.co.uk/blog/uicollectionview-using-horizontal-and-vertical-scrolling-sticky-rows-and-columns
Result will be like this:
You can define a custom cell in IB, which will contain 3 labels and in function:
- (UITableViewCell *)tableView:(UITableView *)aTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *DetailCellIdentifier = #"DetailCell";
UITableViewCell *cell = [aTableView dequeueReusableCellWithIdentifier:DetailCellIdentifier];
if (cell == nil) {
NSArray *cellObjects = [[NSBundle mainBundle] loadNibNamed:#"DetailCell" owner:self options:nil];
cell = (UITableViewCell*) [cellObjects objectAtIndex:0];
}
// setup your cell
}
when you define the cell in IB give each label a tag, so when you need to put a text there you can retrieve it by tag like this:
label = (UILabel *)[cell viewWithTag:NAME_TAG];
label.text = myObject.name;
and repeat this with other 2 labels. The tag is a unique number.
Put this code instead //setup your cell comment
I have created UIGridView. I believe your problem can be solved using the same technique.
You can learn the source code of UIGridView. The code is really short.
Bit late to the party, but we've open sourced our fully featured table component:

Feel free to use!
Create a custom UIView subclass containing, say, three UILabel elements as subviews. Then set the cell's contentView property to this custom view.
add three labels as sub viewsinto uitableview cell's content.then assign apprrpriate values to it
eg:
- (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] autorelease];
}
//frame should be set accordingly(means should be framed accordingly).
UILabel *l1=[[UILabel alloc]initWithFrame:CGRectMake(5, 5, 100,100)];
UILabel *l2=[[UILabel alloc]initWithFrame:CGRectMake(110,10,100,80)];
UILabel *l3=[[UILabel alloc]initWithFrame:CGRectMake(115,60,100,50)];
[cell.contentView addSubview:l1];
[cell.contentView addSubview:l2];
[cell.contentView addSubview:l3];
return cell;
}
