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

In my tableview have custom cells that I initialize from a UITableViewCell class. I have sections for first letters of records and have an indexPath that is being created dynamically.
I wanted to add a search display controller to my tableview. So I did, created all methods to filter data. I am sure that my functions are working well because I am printing array count to screen for search results.
My problem is that the first time view loads, the data is on the screen. But when I hit the search input and type a letter, than I get 'UITableView dataSource must return a cell from tableView:cellForRowAtIndexPath:' error. After I used a breakpoint I saw that my custom cell is nil after searching. Data is exist, but cell is not being initialized.
Here is the code I use for custom cell initializing:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ObjectCell";
SpeakerCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
NSDictionary *myObject = [[sections valueForKey:[[[sections allKeys] sortedArrayUsingSelector:#selector(localizedCaseInsensitiveCompare:)] objectAtIndex:indexPath.section]] objectAtIndex:indexPath.row];
cell.label1.text = [myObject objectForKey:#"myValue"];
return cell;
}
I believe I made a mistake when putting controls in IB. So I added screenshots of objects:
Connections inspector for my table view
Connections inspector for my search display controller
EDIT: Problem is actually solved, I have used a UISearchBar instead of Search Display Controller but I guess this issue remains unsolved. So I'm willing to try any ways to make it work.
As of here search display controller question,
you need to access the self.tableView instead of tableView:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:#"CellId"];
// do your thing
return cell;
}
For those using iOS 5 and StoryBoards, you would want to use the following method instead of initWithIdentifier:
initWithStyle:(UITableViewCellStyle)stylereuseIdentifier:(NSString *)reuseIdentifier
Example:
NSString *cellIdentifier = #"ListItemCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellIdentifier];
}
I'm not sure about how this should work in storeboarding.
But normally you would check if the [tableView dequeueReusableCellWithIdentifier:CellIdentifier] returns a cell.
Because if the cell in not loaded before or there aren't any cells to reuse you will have to create a new cell:
SpeakerCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[SpeakerCell alloc] initWithIdentifier: CellIdentifier];
}
Also when in declaring local variables in Objective-C we tent not to capitalize the first letter.
I had the same issue, with custom cells (built in Storyboard) not being drawn as soon as the first letter was put in the search field. The search was successful however.
Finally I found a good tutorial from Brenna Blackwell suggesting to configure manually the cell drawing in the corresponding subclass of UITableViewCell, adding UILabels and other items.
In my first view I have a UITableView with 5 records. In UITableView cells are holding two different components. One UILabel is text and another UILabel shows value for that cell.
On selection of this UITableViewCell user is navigated to another view where I have given a picker controller for changing the value of 2nd label in the table view for the selected row. I reload the UITableView data on -viewWillAppear but this overlaps the text on lables as many times I visit it.
Can anyone give me relevant example of hierarchical tableview where UItableViewCell's right section is dependant on selection of picker from next view.
I think you are adding the labels on cell.contentView everytime you reload the table, but are not removing the previous ones. Thats why the overlapping is happening.
try to remove the lables
- (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];
}
for (UIView * view in cell.contentView.subviews) {
[view removeFromSuperview];
view = nil;
}
// add your labels
}
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.
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;
}
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...
}
