Trying to change the UITableViewCell text UIColour (costume cell) will make the text become white and unseen, than only when touching the UITableViewCell, I can see the text .
Why setting UIColour to a UITableViewCell that is not blackColor will not work ?
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell =
[self.tableView dequeueReusableCellWithIdentifier:CellIdentifier
forIndexPath:indexPath];
if (!indexPath.row) {
NSDictionary *dic= [[GlobalData sharedGlobals].categories
objectAtIndex:indexPath.section];
cell.textLabel.text = [dic objectForKey:#"title"]; // only top row showing
cell.textLabel.font = [UIFont fontWithName:#"Arial Rounded MT Bold"
size:22];
cell.textLabel.textColor = [UIColor colorWithRed:177
green:218
blue:229
alpha:1];
//cell.textLabel.backgroundColor = [UIColor colorWithRed:218
green:241
blue:245
alpha:1];
} else {
NSMutableArray *typesOfSection =
[[GlobalData sharedGlobals].typesByCategories
objectAtIndex:indexPath.section];
NSDictionary *type = [typesOfSection objectAtIndex:indexPath.row-1];
NSString *titleOfType = [type objectForKey:#"title"];
cell.textLabel.text = titleOfType;
cell.textLabel.textColor = [UIColor colorWithRed:122
green:181
blue:196
alpha:1];
cell.textLabel.font = [UIFont fontWithName:#"Arial Rounded MT Bold"
size:22];
//cell.textLabel.text = #"check";
cell.accessoryView = nil;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
return cell;
}
And when doing this :
cell.textLabel.textColor = [UIColor redColor];
its working..
You are basically setting the cell's text colour to white. The RGB values should be between 0.0 and 1.0.
Try this
[UIColor colorWithRed:122.0/255.0 green:181.0/255.0 blue:196.0/255.0 alpha:1.0];
Use this
You did not add .0f(float) behind each parameter by which you are not getting cell textcolor.
[UIColor colorWithRed:122.0f/255.0f green:181.0f/255.0f blue:196 .0f/255.0f alpha:1.0f];

I am getting this type of data inside cell. How to set the text and detail text of cell so that both text may appear in readable format.
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.font=[UIFont fontWithName: #"Arial" size: 14.0 ];
cell.textLabel.lineBreakMode = NSLineBreakByWordWrapping;
[cell setBackgroundColor:[UIColor whiteColor]];
UILabel *idLabel = (UILabel*)[cell.contentView viewWithTag:201];
if(!idLabel)
{
idLabel = [[UILabel alloc]initWithFrame:CGRectMake(0, 0, 200, 50)];
cell.textLabel.textColor = [UIColor blackColor];
idLabel.tag = 201;
[cell.contentView addSubview:idLabel];
}
idLabel.text = [arrayFiltered objectAtIndex:indexPath.row];
cell.textLabel.text = [idArray objectAtIndex:indexPath.row];
cell.textLabel.textColor = [UIColor grayColor];
cell.detailTextLabel.text = [descArray objectAtIndex:indexPath.row];
cell.detailTextLabel.textColor = [UIColor blueColor];
cell.detailTextLabel.numberOfLines = 2;
cell.detailTextLabel.adjustsFontSizeToFitWidth = YES;
return cell;
}
The code which i have written is above.
Please help me.
We have 3 or more options to achieve this.I explain you step by step process
I create the tableView and hook up.
ViewController.h
#import <UIKit/UIKit.h>
#interface ViewController : UIViewController<UITableViewDataSource,UITableViewDelegate>
#property (strong, nonatomic) IBOutlet UITableView *tblView;
#end
ViewController.m
#import "ViewController.h"
#import "CustomCell.h" // For CustomCell using,we have to import.
#interface ViewController ()
{
NSMutableArray *idArray;
NSMutableArray *descArray;
}
#end
#implementation ViewController
In viewDidLoad method I added the objects to id desc array.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
idArray = [[NSMutableArray alloc]initWithObjects:#"INOX",#"Sathyam",#"PVR",#"IMAX",nil];
descArray = [[NSMutableArray alloc]initWithObjects:#"INOX currently operates 107 multiplexes and 420 screens in 57 cities across India",#"SPI Cinemas is an Indian multiplex chain and film production company owned by the SPI Group, headquartered in Chennai.",#"The IMAX cinema process increases the image resolution by using larger film frame;",#"PVR Cinemas is the largest and the most premium film entertainment company in India.",nil];
}
Below tableView datasource methods
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return idArray.count;
}
Now I have 3 options for achieving your requirement.But all these are implemented in cellForRowAtIndexPath method.
FIRST OPTION:UITableViewCellStyleDefault-If you use this, you can implement the code in cellForRowAtIndexPath like below
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *strCell = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:strCell];
if(cell==nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:strCell];
}
UILabel *idLabel = [[UILabel alloc]init];
idLabel.frame = CGRectMake(15, 13, 168, 24);
idLabel.tag = indexPath.row;
idLabel.numberOfLines = 1;
idLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:18];
idLabel.textAlignment = NSTextAlignmentLeft;
idLabel.textColor = [UIColor blackColor];
idLabel.text = [NSString stringWithFormat:#"%#",[idArray objectAtIndex:indexPath.row]];
[cell.contentView addSubview:idLabel];
UILabel *descLabel = [[UILabel alloc]init];
descLabel.frame = CGRectMake(15, 47, 348, 34);
descLabel.tag = indexPath.row;
descLabel.numberOfLines = 2;
descLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:12];
descLabel.textAlignment = NSTextAlignmentLeft;
descLabel.textColor = [UIColor blueColor];
descLabel.text = [NSString stringWithFormat:#"%#",[descArray objectAtIndex:indexPath.row]];
[cell.contentView addSubview:descLabel];
return cell;
}
SECOND OPTION:UITableViewCellStyleSubtitle - If you use this, you can implement the code in cellForRowAtIndexPath like below
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *strCell = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:strCell];
if(cell==nil)
{
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:strCell];
}
cell.textLabel.text = [NSString stringWithFormat:#"%#",[idArray objectAtIndex:indexPath.row]];
cell.textLabel.tag = indexPath.row;
cell.textLabel.numberOfLines = 1;
cell.textLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:18];
cell.textLabel.textAlignment = NSTextAlignmentLeft;
cell.textLabel.textColor = [UIColor blackColor];
cell.detailTextLabel.text = [NSString stringWithFormat:#"%#",[descArray objectAtIndex:indexPath.row]];
cell.detailTextLabel.tag = indexPath.row;
cell.detailTextLabel.numberOfLines = 2;
cell.detailTextLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:12];
cell.detailTextLabel.textAlignment = NSTextAlignmentLeft;
cell.detailTextLabel.textColor = [UIColor blueColor];
return cell;
}
THIRD OPTION : CUSTOM CELL - If you use Custom Cell you have to import the CustomCell.h first.After that you have to do the following things in cellForRowAtIndexPath method
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
CustomCell *cell = (CustomCell *)[tableView dequeueReusableCellWithIdentifier:#"cell"];
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
if(cell == nil){
cell = nib[0];
}
cell.idLabel.text = [NSString stringWithFormat:#"%#",[idArray objectAtIndex:indexPath.row]];
cell.idLabel.tag = indexPath.row;
cell.idLabel.numberOfLines = 1;
cell.idLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:18];
cell.idLabel.textAlignment = NSTextAlignmentLeft;
cell.idLabel.textColor = [UIColor blackColor];
cell.descLabel.text = [NSString stringWithFormat:#"%#",[descArray objectAtIndex:indexPath.row]];
cell.descLabel.tag = indexPath.row;
cell.descLabel.numberOfLines = 2;
cell.descLabel.font = [UIFont fontWithName:#"HelveticaNeue" size:12];
cell.descLabel.textAlignment = NSTextAlignmentLeft;
cell.descLabel.textColor = [UIColor blueColor];
return cell;
}
I attached the screen shot of custom cell.It shows you what I have done there.
SNAPCHAT 1:idLabel
SNAPCHAT 2:descLabel
You can use heightForRowAtIndexPath method for setting row height.It is UITableViewDelegate method
-(CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 90;
}
NOTE:Generally I set the tag for label is idLabel.tag = indexPath.row.According
to your requirement set the tag here.
I created and worked out the sample application for you.All I have done successfully.
Use cell textLable and detailTextLable to show your data like below code-
cell.textLabel.text=#"your text";
cell.detailTextLabel.text=#"your text";
idLabel overrides the position of the textlabel .
If
you want to put the id before the text , You can combine both the string and put into the textlabel.
else
use dont use textlabel and detail textlabel, create all the three labels of your own and align properly using Frame values.
Check the Height of the Cell and calculate it according to the Cell Text and number of lines of Label. And move your Font, Background Color, Line Break settings of label inside cell == nil.
Edit: to adjust three Labels you would need custom Cell or if you can concatenate it with Text Label. It all depends on your requirement.
I've got a UITableView and as the cellForRowAtIndexPath method I am changing some attributes of the cell (font, size, etc.) Now all of the assignments listed below work just fine except changing the color of the textLabel. I can't figure out why only that specific color attribute won't change. I've looked about everywhere I can think of to figure out why it isn't working and I'm stuck. Any ideas?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *kLocationAttributeCellID = #"bAttributeCellID";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:kLocationAttributeCellID];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:kLocationAttributeCellID] autorelease];
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
cell.detailTextLabel.font = [UIFont fontWithName:#"Helvetica" size:14.0];
cell.detailTextLabel.numberOfLines = 0;
cell.detailTextLabel.lineBreakMode = UILineBreakModeWordWrap;
cell.userInteractionEnabled = NO;
cell.textLabel.font = [UIFont fontWithName:#"Courier" size:18.0];
cell.textLabel.textColor = [UIColor redColor]; // this never takes effect...
}
cell.textLabel.text = #"Test Label";
cell.detailTextLabel.text = #"Test Details";
return cell;
}
It's because of this:
cell.userInteractionEnabled = NO;
If you don't want your cells to be selectable, try using this instead:
cell.selectionStyle = UITableViewCellSelectionStyleNone;
I am making an app which shows sport results and color codes them accordingly by setting their cell's background color:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Cell"];
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"Cell"];
if (_tabBar.selectedItem == _homeGamesItem) {
cell.backgroundColor = [UIColor whiteColor];
cell.detailTextLabel.text = #"";
cell.textLabel.text = [NSString stringWithFormat:#"Home Game %d", indexPath.row];
} else if (_tabBar.selectedItem == _myEventsItem) {
cell.backgroundColor = [UIColor whiteColor];
cell.detailTextLabel.text = #"";
cell.textLabel.text = [NSString stringWithFormat:#"My Result %d", indexPath.row];
} else if (_tabBar.selectedItem == _resultsItem) {
SportEvent *event = [self.appDelegate.user.resultSportEvents objectAtIndex:indexPath.row];
if ([event.gender isEqualToString:#""]) {
cell.textLabel.text = [NSString stringWithFormat:#"%# %#", event.level, event.activity];
cell.detailTextLabel.text = event.result;
} else {
cell.textLabel.text = [NSString stringWithFormat:#"%# %# %#", event.gender, event.level, event.activity];
cell.detailTextLabel.text = event.result;
}
if ([[event.result substringToIndex:1] isEqualToString:#"W"])
cell.backgroundColor = [UIColor colorWithRed:0 green:1 blue:0 alpha:.05];
else if ([[event.result substringToIndex:1] isEqualToString:#"T"])
cell.backgroundColor = [UIColor colorWithRed:1 green:1 blue:0 alpha:.05];
else if ([[event.result substringToIndex:1] isEqualToString:#"L"])
cell.backgroundColor = [UIColor colorWithRed:1 green:0 blue:0 alpha:.05];
}
if (_grayedOut) {
cell.textLabel.textColor = [UIColor grayColor];
cell.detailTextLabel.textColor = [UIColor grayColor];
} else {
cell.textLabel.textColor = [UIColor blackColor];
cell.detailTextLabel.textColor = [UIColor blackColor];
}
return cell;
}
The strange thing is that this causes some cells to have strange backgrounds right around the labels (my apologies for the massive image):
Why do only some cells get this strange darkening around the labels?
Since you use these cells in other tabs, and you only change some cell's background color to white (e.g. homeGames), then add the following code to make all reusable cells have the same color (clearColor) before actually using them again:
...
if (cell == nil)
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:#"Cell"];
//Add This Code
cell.backgroundColor = [UIColor clearColor];
//Also make labels same color just to be sure
cell.textLabel.backgroundColor = [UIColor clearColor]; //or whiteColor
cell.detailTextLabel.backgroundColor = [UIColor clearColor]; //or whiteColor
if (_tabBar.selectedItem == _homeGamesItem) {
...

I have problem with the cell background color becoming clearcolor always. I set the uiview background color to gray color, tableview background color to clear color and I did not set tableviewcell background color to clear color. But the cell background always appears grey. Can any one have any idea about this.
Thanks

Try setting your cell's background colour in the method
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
rather than in your cellForRowAtIndexPath: method.
Your cells are not exactly transparent. Setting UITableView's backgroundColor does some crazy undocumented stuff. Best way to see this is to set it to some semi-transparent color like [UIColor colorWithWhite:0.5 alpha:0.5] by which you get something like this:
To fix your problem, you will have to set cells' contentView.backgroundColor and backgroundColors of all the subviews after setting tableView's. Here is your cellForRowAtIndexPath: updated with this:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"TransCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UIColor *cellBackgroundColor = [UIColor whiteColor];
switch ([Acc_Details_SegCtrl selectedSegmentIndex]) {
case 0:{
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"TableCell"] autorelease];
cell.textLabel.font = [UIFont boldSystemFontOfSize:14];
cell.detailTextLabel.text = [[transcationsList objectAtIndex:([indexPath row])] valueForKey:#"Date"];
cell.detailTextLabel.font = [UIFont systemFontOfSize:12];
cell.accessoryView.backgroundColor = cellBackgroundColor;
cell.backgroundView.backgroundColor = cellBackgroundColor;
cell.contentView.backgroundColor = cellBackgroundColor;
cell.textLabel.backgroundColor = cellBackgroundColor;
cell.detailTextLabel.backgroundColor = cellBackgroundColor;
UIView *backView = [[UIView alloc] initWithFrame:cell.frame];
backView.backgroundColor = cellBackgroundColor;
cell.backgroundView = backView;
[backView release];
}
NSString *titleName =[[transcationsList objectAtIndex:([indexPath row])] valueForKey:#"Title"] ;
if ([titleName length] > 19) {
cell.textLabel.text = [titleName substringWithRange:NSMakeRange(0, 20)];
}
else{
cell.textLabel.text = titleName;
}
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
UILabel * acc_Amount = [[UILabel alloc] initWithFrame:CGRectMake(220, 5, 60,10)];
acc_Amount.textAlignment = UITextAlignmentRight;
acc_Amount.backgroundColor = cellBackgroundColor;
acc_Amount.text = [[transcationsList objectAtIndex:([indexPath row])] valueForKey:#"Amount"];
acc_Amount.font = [UIFont boldSystemFontOfSize:14];
[cell.contentView addSubview:acc_Amount];
UILabel * balance_Amount = [[UILabel alloc] initWithFrame:CGRectMake(220, 23, 60,10)];

I didn't understand your question. You set the table's background to grey, then clear, but you didn't set it as clear, and then it appears grey, which you didn't want even though you set it as grey?
table.backgroundColor = [UIColor clearColor];
