Currently when scrolling upwards in my tableView I have found a strange and annoying bug. When I decide to release the "scroll", meaning I am dropping "the scroll" so the "View" will return to its normal position showing all of the TableView's content, some of my cell's can for some reason re-size themselves on the width. I have no clue why this occur or what the problem might be.
My cell's (commentLabel) are customized to fitSize depending on the height of the label in my forum. I assume the problem may be in how I am trying to customize my cell's content. I will post my relevant code and also post to pictures below.
Before starting to drag the scroll upwards: http://tinypic.com/view.php?pic=2rfsum9&s=6
After release/droped the scroll again to its normal position. Now one of the cell's changed: http://tinypic.com/view.php?pic=swxnqv&s=6
Code:
- (UITableViewCell *)tableView:(UITableView *)pTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ForumthreadCell";
UITableViewCell *cell = [pTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Feedback *item = [self.items objectAtIndex:indexPath.row];
UILabel *aliasLabel = (UILabel *)[cell viewWithTag:1];
UILabel *commentLabel = (UILabel *)[cell viewWithTag:2];
UILabel *dateLabel = (UILabel *)[cell viewWithTag:3];
[aliasLabel setText:item.alias];
[commentLabel setText:item.comment];
[dateLabel setText:[self.dateFormatter stringFromDate:[NSDate dateWithTimeIntervalSince1970:(double)item.time]]];
commentLabel.numberOfLines = 0;
[commentLabel sizeToFit];
return cell;
}
-(CGFloat)getLabelHeightForText:(NSString *)text andWidth:(CGFloat)labelWidth
{
CGSize maximumSize = CGSizeMake(labelWidth, 10000);
//provide appropriate font and font size
CGSize labelHeighSize = [text sizeWithFont: [UIFont fontWithName:#"Trebuchet MS" size:12.0f]
constrainedToSize:maximumSize
lineBreakMode:UILineBreakModeTailTruncation];
return labelHeighSize.height;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
Feedback *item = [self.items objectAtIndex:indexPath.row];
CGFloat commentTextHeight = [self getLabelHeightForText:item.comment andWidth:162];
return commentTextHeight + 39;
}
EDIT
The new code:
CGRect frame = commentLabel.frame;
frame.size.width = kLabelWidth;
frame.size.height = 10000;
commentLabel.frame = frame;
frame = commentLabel.frame;
frame.size.height += kOffset;
commentLabel.frame = frame;
But I have done something wrong since now the text from the commentLabel is not getting displayed correctly, can anyone se my fault here in how I try to set the frame? This is what the cell's look like now http://oi50.tinypic.com/2w5u0s6.jpg
The new full code:
static const CGFloat kLabelWidth = 162;
static const CGFloat kOffset = 39;
- (UITableViewCell *)tableView:(UITableView *)pTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ForumthreadCell";
UITableViewCell *cell = [pTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Feedback *item = [self.items objectAtIndex:indexPath.row];
UILabel *aliasLabel = (UILabel *)[cell viewWithTag:1];
UILabel *commentLabel = (UILabel *)[cell viewWithTag:2];
UILabel *dateLabel = (UILabel *)[cell viewWithTag:3];
[aliasLabel setText:item.alias];
[commentLabel setText:item.comment];
[dateLabel setText:[self.dateFormatter stringFromDate:[NSDate dateWithTimeIntervalSince1970:(double)item.time]]];
CGRect frame = commentLabel.frame;
frame.size.width = kLabelWidth;
frame.size.height = 10000;
commentLabel.frame = frame;
frame = commentLabel.frame;
frame.size.height += kOffset;
commentLabel.frame = frame;
commentLabel.numberOfLines = 0;
[commentLabel sizeToFit];
return cell;
}
You should adjust label frames before reusing cells. In your case you are changing cells height while reusing it in
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
but you should also adjust label's frame according to cell's height so that it will not go beyond cell's bound.

I found a lot of answer for this question but I don't anderstand how to manage my code.
When I scroll the tableView content, the cell disappear. I just have two texts in the cell question and answer.
I've tried to use an identifier (reusable) but the code doesn't change anything...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UILabel *textLabel = nil;
NSString* text = #"";
//static NSString *CellIdentifier = #"Cell";
NSString *CellIdentifier = [NSString stringWithFormat:#"%ld_%ld",(long)indexPath.section,(long)indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
int y = -20;
float titleFontSize = 14.0f;
if(indexPath.row == 0) {
y = 0;
titleFontSize = 16.0f;
}
if(cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"Cell"];
textLabel = [[UILabel alloc] initWithFrame:CGRectZero];
[textLabel setLineBreakMode:NSLineBreakByWordWrapping];
[textLabel setMinimumFontSize:14.0f];
[textLabel setNumberOfLines:0];
[textLabel setFont:[UIFont systemFontOfSize:14.0f]];
[textLabel setTag:1];
[textLabel setTextColor:[UIColor colorWithRed:57/255.0 green:55/255.0 blue:64/255.0 alpha:1.0]];
// Titre
if(indexPath.row == 0) {
text = question;
[cell setBackgroundColor:[UIColor colorWithRed:220/255.0 green:224/255.0 blue:241/255.0 alpha:1.0]];//[UIColor colorWithRed:.945f green:.921f blue:.78f alpha:1]];
[textLabel setFont:[UIFont fontWithName:#"Helvetica-Bold" size:titleFontSize]];
}
// Contenu
else {
text = answer;
}
CGSize constraint = CGSizeMake(285, 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:titleFontSize] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
[textLabel setText:text];
[textLabel setFrame:CGRectMake(25, y, 275, MAX(size.height + 60, 44.0f))];
[textLabel setBackgroundColor:[UIColor clearColor]];
[cell addSubview:textLabel];
return cell;
}
UPDATE CALCULATING CELL SIZE
-(float)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
float titleFontSize = 14.0f;
float offSet = 0;
NSString *text = #"";
if(indexPath.row == 0) {
text = question;
titleFontSize = 16.f;
offSet = 10;
}
else
text = answer;
CGSize constraint = CGSizeMake(285, 20000.0f);
CGSize size = [text sizeWithFont:[UIFont systemFontOfSize:titleFontSize] constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height + 40, 44.0f);
return height + offSet;
}
I've had this problem in the past and it's always due to the cells height being incorrect... You've got quite a few instances where your two cells are not the same, so we are going to have to get a grip on that code.
int y
this value is also concerning me a little as it looks like it sets the textLabel frame origin.y to -20 ... if you want a different offset for Y in each cell but the rest of the cell is the same, that's fine, but in this case I think I'd suggest a different UITableViewCell subclass for the two types of cell... And change all the label properties etc inside that subclass..
So...
Make a UITableViewCell subclass for each type of cell, call them whatever you like... for example MYQuestionTableViewCell and MYAnswerTableViewCell
inside the cell MYQuestionTableViewCell .h file
#define TEXT_LABEL_WIDTH 285.0f
#define TEXT_LABEL_QUESTION_FONT_SIZE 16.0f
inside that cell MYQuestionTableViewCell .m file do
- (id)initWithStyle:(UITableViewCellStyle)style reuseIdentifier:(NSString *)reuseIdentifier
{
self = [super initWithStyle:style reuseIdentifier:reuseIdentifier];
if (self) {
self.backgroundColor = [UIColor redColor];
self.clipsToBounds = YES; // just to make sure we're calculating the height correctly
// set up your textLabel etc. in here
self.textLabel.textColor = [UIColor whiteColor];
self.textLabel.font = [UIFont fontWithName:#"Helvetica-Bold" size: TEXT_LABEL_QUESTION_FONT_SIZE]];
}
return self;
}
-(void)layoutSubviews
{
[super layoutSubviews];
self.textLabel.frame = CGRectMake(0.0f, 0.0f, TEXT_LABEL_WIDTH, self.contentView.frame.size.height);
}
Now our textLabel will be whatever the height of the cell is... Now it's set in only one place, we know where the issue will be if it's not correct.
In your second MYAnswerTableViewCell subclass you'll need the other values set
.h
#define TEXT_LABEL_ANSWER_FONT_SIZE 14.0f
.m
same as the other cell but changing for it's property values
As you are also using different fonts in the two different cells... it might be easier to use a switch.. but I'll try to keep it similar to what you were doing before.. this sort of doubling up of code is the cause of the confusion, but sometimes it's unavoidable.. We'll just try to keep it as simple as we can.
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
CGFloat offSet = 0.0;
NSString *text = #"";
UIFont *fontUsed = nil;
if(indexPath.row == 0) {
fontUsed = [textLabel setFont:[UIFont fontWithName:#"Helvetica-Bold" size: TEXT_LABEL_QUESTION_FONT_SIZE]];
text = question;
offSet = 10.0f;
}
else
{
fontUsed =[UIFont systemFontOfSize:TEXT_LABEL_ANSWER_FONT_SIZE];
text = answer;
}
NSLog (#"TEXT: %#",text); // checking if the text is set...
CGSize constraint = CGSizeMake(TEXT_LABEL_WIDTH, HUGE_VALF); // personally I prefer HUGE_VALF for that
CGSize size = [text sizeWithFont:fontUsed constrainedToSize:constraint lineBreakMode:NSLineBreakByWordWrapping];
CGFloat height = MAX(size.height + 40.0f, 44.0f); // 40.0f for padding?
return height + offSet;
}
You shouldn't be adding labels to a cell unless you need to, they come with some provided... now your cellForRow can look like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *QuestionCellIdentifier = #"QuestionCell";
static NSString *AnswerCellIdentifier = #"AnswerCell";
if (indexPath.row == 0)
{
MYQuestionTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:QuestionCellIdentifier];
if (!cell)
cell = [[MYQuestionTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:QuestionCellIdentifier];
cell.textLabel.text = question;
return cell;
}
MYAnswerTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: AnswerCellIdentifier];
if (!cell)
cell = [[MYAnswerTableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:AnswerCellIdentifier];
cell.textLabel.text = answer;
return cell;
}
You'll also need
#import "MYQuestionTableViewCell.h"
#import "MYAnswerTableViewCell.h"
at the top of your view controller
I have a UITableViewCell that has a UITextView. When the table loads all of the text in each UITextView appears in a single line. I created the UITextView in IB with a white text color. How do I get it to display in multiple lines, and why did the text color switch to black?
The height of each UITableViewCell is correct. It used to display the text in multiple lines after I refreshed the table by pulling down, but for some reason that stopped working too.
If there's any other information you require, please let me know.
Here's the relevant code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath object:(PFObject *)object {
BIDChatCell *cell = (BIDChatCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[BIDChatCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// Configure the cell
cell.backgroundColor = [UIColor clearColor];
cell.userLabel.text = [object objectForKey:#"username"];
NSString *time = [object objectForKey:#"time"];
NSString *date = [time substringToIndex:10];
cell.timeLabel.text = date;
NSString *chatText = [object objectForKey:#"text"];
UIFont *font = [UIFont systemFontOfSize:14];
CGSize size = [chatText sizeWithFont:font constrainedToSize:CGSizeMake(200.0f, 1000.0f) lineBreakMode:UILineBreakModeCharacterWrap];
cell.textStringView.frame = CGRectMake(75, 15, size.width +20, size.height + 20);
cell.textStringView.font = [UIFont fontWithName:#"Helvetica" size:14.0];
cell.textStringView.text = chatText;
[cell.textStringView sizeToFit];
[cell.textStringView.textContainer setSize:cell.textStringView.frame.size];
CGRect frame = cell.textStringView.frame;
frame.size.height = cell.textStringView.contentSize.height;
cell.textStringView.frame = frame;
[cell layoutSubviews];
return cell;
}
Here's an image:
Try setting the height of the textView like so:
CGRect frame = cell.textStringView.frame;
frame.size.height = cell.textStringView.contentSize.height;
cell.textStringView.frame = frame;
Does the UITextView have the proper autoresizingMask?
It likely needs it set to (UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight) to allow the textview to grow (as it normally uses a UIScrollView instead)
I'm trying to create a tableview where the height of the cells are dynamic.
So far I manage to set the height of the cells depending on the custom UILabel I've added inside.
With the regular cell.textLabel it works fine, but when I use my own label something goes wrong. I only see half the label, but when I scroll up and down, sometimes the label extends and shows all the text... You can see where the label should end in the image.

This is the text inside the cellForRowAtIndexPath:
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell.
Car *carForCell = [cars objectAtIndex:indexPath.row];
UILabel *nameLabel = [[UILabel alloc] init];
nameLabel = (UILabel *)[cell viewWithTag:100];
nameLabel.numberOfLines = 0;
nameLabel.text = carForCell.directions;
[nameLabel sizeToFit];
[nameLabel setBackgroundColor:[UIColor greenColor]];
return cell;
Unless you have typos in the code you posted, you don't seem to be adding the label to the cell at all. You also seem to be creating a new label every time, and then replacing the contents of your nameLabel pointer with the cell's view (which will always be nil).
Try doing something like this first and then see how it looks:
static NSString *CellIdentifier = #"Cell";
UILabel *nameLabel;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
nameLabel = [[UILabel alloc] init];
nameLabel.tag = 100;
nameLabel.numberOfLines = 0;
[nameLabel setBackgroundColor:[UIColor greenColor]];
[cell.contentView addSubview:nameLabel];
}
else {
nameLabel = (UILabel *)[cell viewWithTag:100];
}
// Configure the cell.
Car *carForCell = [cars objectAtIndex:indexPath.row];
nameLabel.text = carForCell.directions;
[nameLabel sizeToFit];
return cell;
You will also need to tell the tableView what size each cell needs to be using the tableView:heightForRowAtIndexPath: delegate method. That will mean getting the relevant Car object again and calculating the height using sizeWithFont:sizeWithFont:forWidth:lineBreakMode:
How are you setting the height of the cell? It should be done in - (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
You should calculate and return the height of the UITableViewCell in the following method:
- (CGFloat) tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath;
Here you should do your initial calculation of how high your cell should be.
For example:
CGSize textSize = [myString sizeWithFont:[UIFont systemFontOfSize:16] constrainedToSize:CGSizeMake(320, 9999)];
return textSize.height;
How can I scale UITableViewCells based on the amount of content in them? In my cells I use 3 labels which represent a forum. The labels are named "alias", "date", and "comments". The third label comments, can be any number of size. Therefore, my cells need to become dynamically depending on how big the "comments" label is. Below is my relevant code:
- (UITableViewCell *)tableView:(UITableView *)pTableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"ForumthreadCell";
UITableViewCell *cell = [pTableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
Feedback *item = [self.items objectAtIndex:indexPath.row];
UILabel *aliasLabel = (UILabel *)[cell viewWithTag:1];
UILabel *commentLabel = (UILabel *)[cell viewWithTag:2];
UILabel *dateLabel = (UILabel *)[cell viewWithTag:3];
[aliasLabel setText:item.alias];
[commentLabel setText:item.comment];
[dateLabel setText:[self.dateFormatter stringFromDate:[NSDate dateWithTimeIntervalSince1970:(double)item.time]]];
commentLabel.numberOfLines = 0;
[commentLabel sizeToFit];
CGSize textHeight = [commentLabel.text sizeWithFont:commentLabel.font constrainedToSize:CGSizeMake(maxWidth, lineHeight * commentLabel.numberOfLines)lineBreakMode:UILineBreakModeWordWrap];
return cell;
}
As you can see, I set the height of the commentsLabel with textHeight. But what shall I do from now on? If I know the height of the label, how can I set the Cell's height depending on commentLabel's height?. Please give code-examples based on my code. I think I should use the following method but I am not sure how to do it:
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
}
Use this method to get the text height of the text
-(CGFloat)getLabelHeightForText:(NSString *)text andWidth:(CGFloat)labelWidth
{
CGSize maximumSize = CGSizeMake(labelWidth, 10000);
//provide appropriate font and font size
CGSize labelHeighSize = [text sizeWithFont: [UIFont fontWithName:#"Trebuchet MS" size:13.0f]
constrainedToSize:maximumSize
lineBreakMode:UILineBreakModeTailTruncation];
return labelHeighSize.height;
}
This method will return the height of the text you are passing. Add this method in your class. And use the tableView:heightForRowAtIndexPath: delegate method to set the height for each cell
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
Feedback *item = [self.items objectAtIndex:indexPath.row];
CGFloat textHeight = [self getLabelHeightForText:item.comment andWidth:162];//give your label width here
return textHeight;
}
I think this could solve the problem.
You could make the Label declarations in your implementation:
#implementation pTableView
{
UILabel *aliasLabel;
}
Then in the row height you could use default Height (44) + aliasLabel.Height
return 44 + aliasLabel.frame.size.height;
Then if you need to differentiate between the labels in your table
aliasLabel.tag = indexpath.row
I've added a tableView and dragged a table view cell into it.
in the utilities panel, I changed the style to subtitle.
I've also tried changing it in code:
- (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];
}
cell.textLabel.textAlignment = UITextAlignmentCenter;
cell.detailTextLabel.textAlignment = UITextAlignmentCenter;
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
cell.detailTextLabel.text = [myArray2 objectAtIndex:indexPath.row];
return cell;
The center alignment doesn't work!
I've tried adding a label object to the cell to have a workaround. But I don't know how to access it. even though I assigned an outlet to it, this wouldn't work:
cell.labelForCell....
What should I do?
any suggestions on how I make it work the usual way, without adding a label to the cell or something?
For the UITableViewCellStyleSubtitle text alignment cannot be changed
You will have to put a label and add your alignment to it,
To do that you could use this code
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UILabel *myLabel;
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
myLabel = [[UILabel alloc] initWithFrame:Your_Frame];
//Add a tag to it in order to find it later
myLabel.tag = 111;
//Align it
myLabel.textAlignment= UITextAlignmentCenter;
[cell.contentView addSubview:myLabel];
}
myLabel = (UILabel*)[cell.contentView viewWithTag:111];
//Add text to it
myLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}
The problem with the subtitle style is that it does a [self.textLabel sizeToFit] when it lays out. When you center in a container that is the perfect size of the contents, nothing changes.
Try this. In a subclass of UITableViewCell, set your textAlignment, and use this as your layoutSubviews code:
- (void)layoutSubviews
{
[super layoutSubviews];
{
CGRect frame = self.textLabel.frame;
frame.size.width = CGRectGetWidth(self.frame);
frame.origin.x = 0.0;
self.textLabel.frame = frame;
}
{
CGRect frame = self.detailTextLabel.frame;
frame.size.width = CGRectGetWidth(self.frame);
frame.origin.x = 0.0;
self.detailTextLabel.frame = frame;
}
}
This makes the textLabel's frame full width, and thus allows the centering effect to be noticeable.
Note: since this overrides layoutSubviews, there is a performance cost as it will be called often.
I think the reason is that: the textLabel's width depends on the text length, if the text is too long to show all in a signal line, and you have already set the line break mode and set the number of lines to 0, you will find that the text alignment will be work.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *identifier = #"identifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (nil == cell)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:identifier] autorelease];
cell.textLabel.textAlignment = UITextAlignmentLeft;
cell.textLabel.textColor = [UIColor redColor];
cell.detailTextLabel.textColor = [UIColor greenColor];
cell.detailTextLabel.textAlignment = UITextAlignmentCenter;
cell.textLabel.lineBreakMode = UILineBreakModeTailTruncation;
cell.textLabel.numberOfLines = 0;
}
cell.textLabel.text = [NSString stringWithFormat:#"You can initialize a very long string for the textLabel, or you can set the font to be a large number to make sure that the text cann't be shown in a singal line totally:%d", indexPath.row];
return cell;
}
I think adjusting the frame will work. I had style of UITableViewCellStyleValue2 but If i have a bit lengthy text in textLabel, it getting truncated at tail and textAlignment does not work here, so thought of increase the width textLabel.
-(void)layoutSubviews{
[super layoutSubviews];
if ([self.reuseIdentifier isEqualToString:#"FooterCell"]) {
CGRect aTframe = self.textLabel.frame;
aTframe.size.width += 40;
self.textLabel.frame = aTframe;
CGRect adTframe = self.detailTextLabel.frame;
adTframe.origin.x += 70;
self.detailTextLabel.frame = adTframe;
}
}
It is impossible to change frame for textLabel and detailTextLabel in UITableViewCell
right in cellForRowAtIndexPath: method.
If you don't want to subclass your cell you can implement a small hack using
performSelector:withObject:afterDelay:
with zero delay for changing geometry right after default layoutSubviews:
[self performSelector:#selector(alignText:) withObject:cell afterDelay:0.0];
See details at here
Hi please add the following instead of your code,
cell.textLabel.textAlignment = UITextAlignmentCenter;
cell.detailTextLabel.textAlignment = UITextAlignmentCenter;
change to
cell.textLabel.textAlignment = NSTextAlignmentCenter;
cell.detailTextLabel.textAlignment = NSTextAlignmentCenter;
it will work fine.
