How can i make my UITableViewCell contain two labels? - iphone

I want my UITableViewCell to look like the image below where there seems to be two labels. Is this possible without subclassing UITableViewCell?

There are different styles of UITableVieWCell. See here:
https://developer.apple.com/documentation/uikit/uitableviewcell/cellstyle
I think you want to use UITableViewCellStyleValue1.
You can initialise your UITableViewCell with the relevant style:
https://developer.apple.com/documentation/uikit/uitableviewcell/1623276-init
When you use a style that has two labels, you can use the textLabel and detailTextLabel properties to set them, respectively.

You do not need to subclass a UITableViewCell in order to add content to it. Here could be a sample cell generation method with an extra label:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *identifier = #"Identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:identifier] autorelease];
UILabel *secondLabel = [[UILabel alloc] initWithFrame:cell.textLabel.frame];
secondLabel.textAlignment = UITextAlignmentRight;
secondLabel.tag = 12345;
[cell.contentView addSubview:secondLabel];
}
UILabel *second = [cell viewWithTag:12345];
second.text = #"Second!";
return cell;
}
Let me know if you have any questions. I can clarify some things if needed.

Not sure where u think you see 2 labels...you can set the UILabels number of lines property if you want more lines UILabel ref....Also there is a UITableViewCell type UITableViewCellStyleSubtitle
which contains a detailTextLabel on top of the regular text labels in UITableCell, so you already have a built in cell with 2 text fields, here is a ref ref to UITableViewCell

Its not 2 labels but 2 buttons, you need to add 2 buttons in contentView view of the cell. Or you can create a footer or header View and add these 2 buttons.

Most optimum way to add views in a Custom UITableViewCell

I have seen a lot of examples and I cannot find the best answer.
Imagine that I have a custom cell with a 120 height, with 3 UILabels and a UIImageView.
I init my cell with
-(id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
Of all the approaches, which one its the most optimum?
Probably the best answer for creating custom tables is at the link below, if you then have specific questions about the code you see there, then feel free to ask more questions.
http://cocoawithlove.com/2009/04/easy-custom-uitableview-drawing.html
All you have to do is something like this:
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Prototype Cell"];
UILabel *label;
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:#"Prototype Cell"];
label = [[UILabel alloc] init];
label.tag = LABEL_TAG; //Suppose LABEL_TAG is defined someplace else
[cell.contentView addSubview: label];
}
else
{
label = [cell.contentView viewWithTag:LABEL_TAG];
}
label.text = #"Hello World";
//Suppose you want the label at x coordinate 50
label.frame = CGRectMake(0,0,50,120);
//Follow similar steps for all of your subviews
return cell;
}
Create a custom UITableviewCell by subclassing the UITableViewCell & overide the method initWithStyle.You can alloc the labels in this init method & also add this label in the cell in this method.
You can also create the UItableViewCell by using nib files.

How to Align the text of my label?

I want to align the text of my label to right aligned. But the problem is my label is in UITableVIewCell and i am using 'Value1' of UITableViewCell. So i want to align detailText label to the right side of the cell but sometimes the labels is in two or three lines so in that case i want the next line of the label to be left aligned so that it looks the next line is starting from left.
Please help!!!!
You can use custom tableview cells. Add a UITableViewCell class to your project and call it CustomCell, create a TableViewCell in Iterface Builder. Add two Labels, One right aligned called "label1", the other one left aligned called "label2", or do what ever you want, Then you can use it in your main class like this:
#import "CustomCell.h"
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
cell.label1.text = #"some rightAlignedText";
cell.label2.text = #"some leftAlignedText";
return cell;
}
You need to look at a different cell type or create your own custom one because as far as I know, the way each table cell is laid out is set in stone

UIImageView simply does not appear in custom UITableViewCell

I have a table cell to which I'm adding subviews programmatically. All the textual subviews work fine, but I can't get an image subview working at all.
You'll notice that I set the background color to black. This is simply to indicate to me that the subview is indeed being initialized and positioned properly within the cell. When I remove the background color there is nothing there.
Also, the cell style is UITableViewCellStyleDefault but I don't think that's pertinent for custom subviews. I want the image positioned on the right, which is why I'm not using the standard imageView property that cells offer.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
// ... add textual views ...
UIImageView *img = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"clock.png"]];
img.frame = CGRectMake(271.0f, 10.0f, 19.0f, 22.0f);
img.backgroundColor = [UIColor blackColor];
[cell addSubview:img];
}
// ... more code ...
return cell;
}
Your code looks fine to an extent. One issue I had when I was creating my own UITableViewCells in code was I was creating the cells with variables like you are but you shouldn't do this.
What you should do is create the cell and then set the variables. If cells are different you should use different reuse identifiers. Hope this makes sense if not let me know and I'll update.

How to display multiple columns in a UITableView?

I want to display multiple columns in a UITableView.
For Example:
TableView
FName LName Age
----- ----- ---

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;
}

UITextView in iphone

i am creating textview(editable) through coding in uitableview in cellforrowatindexpath delegate. textview is showing in every row correctly. the problem is that when i am enter text in textview and scroll the tableview, then text disappear from textview. if anyone has any idea?
When you go to edit the text in the textview, the text scrolls up so that the top of the textview is where the new text will appear when typed. Try swiping down on the textview to reveal the previous info.
Make sure you are adding a different textview to each of the different reusable cells. If you have, say, 6 cells visible at any time, then you need 6 different textviews.
It sounds like when you scroll, your textview gets used for another cell.
// Customize the appearance of table view cells.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
MyTableCell *cell = (MyListTableCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
cell.textView = [[[UITextView alloc] initWithFrame:/** put appropriate rect here **/] autorelease];
// create other cell structures you need
}
// Set up the cell...
}
