I need to use UITableViewCellSelectionStyleBlue for the cell selection style. But whatever style I set it only displays UITableViewCellSelectionStylegray. I am using Xcode 5.
This is my code:
-(UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellid = #"Table1";
UITableViewCell * cell = [tableView dequeueReusableCellWithIdentifier:cellid];
if (cell==Nil) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellid];
}
cell.textLabel.text = [tabledata objectAtIndex:indexPath.row];
cell.selectionStyle =UITableViewCellSelectionStyleBlue;
cell.imageView.image =[UIImage imageNamed:#"cellbgimg.png"] ;
return cell;
}
i am able to change the UITableviewSelectionStyleBlue. Please try below code:
// take a view for the cell...
UIView *cellBg = [[UIView alloc] init];
cellBg.backgroundColor = [UIColor colorWithRed:(76.0/255.0) green:(161.0/255.0) blue:(255.0/255.0) alpha:1.0]; // this RGB value for blue color
cellBg.layer.masksToBounds = YES;
Cell.selectedBackgroundView = cellBg;
Try this one ....
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:#"myCell"];
if (cell == nil)
{
cell = [self tableviewCellWithReuseIdentifier:#"myCell" ForIndexpath:indexPath];
}
[self configureCell:cell forIndexPath:indexPath];
cell.accessoryType = UITableViewCellAccessoryNone;
[cell setSelectionStyle:UITableViewCellSelectionStyleBlue]; // This one for your cell selection style.
return cell;
}

I believe I'm doing this correctly but it doesn't seem to be working? The text for the cell is written indicating the if statement is correct and is running, However the cell accessory is not changing.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
if (indexPath.section==0) {
if ([[tableContents objectAtIndex:indexPath.row] isEqual: #"New Time"]) {
cell.tintColor = [UIColor redColor];
cell.textLabel.text = [tableContents objectAtIndex:indexPath.row];
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
}
else{
cell.textLabel.text = [tableContents objectAtIndex:indexPath.row];
}
}
else{
cell.textLabel.text = [tableContents objectAtIndex:indexPath.row];
}
return cell;
}
Thanks for any help in advance!
Okay so tried slimming the code down to try and see whats going on, now this crashes when the view is loaded, totally confused as i have another project where this is working perfectly!
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"UserCells";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
// Configure the cell...
cell.textLabel.text = #"Hello";
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
return cell;
}
Setting the cell tint color in cellForRowAtIndexPath did work:
cell.tintColor = [UIColor redColor]; // whatever you want
I have a tableView which lists student names and highlights the row green for present or red for absent. If you click the row, the color is changed to reflect and change in status for the student.
However, when a student is marked absent (highlighted red) and then I scroll the row out of view the row turns grey. I would love for the row to remain red (ugh).
Here are the tableView methods
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [kidsNames count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"myCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil){
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [kidsNames objectAtIndex:(indexPath.row)];
NSString * status=[kidsAbsent objectAtIndex:indexPath.row];
if([status isEqualToString: #"Present"]==1){
cell.contentView.backgroundColor = [UIColor greenColor];
}else{
cell.contentView.backgroundColor = [UIColor redColor];
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString * ab=[kidsAbsent objectAtIndex:indexPath.row];
static NSString *CellIdentifier = #"myCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"CLICKED!");
if([ab isEqualToString: #"Present"]==1){
[kidsAbsent replaceObjectAtIndex:indexPath.row withObject:#"Absent"];
cell.contentView.backgroundColor = [UIColor redColor];
NSLog(#"Now Absent %#",[kidsNames objectAtIndex:(indexPath.row)]);
}else{
cell.contentView.backgroundColor = [UIColor greenColor];
[kidsAbsent replaceObjectAtIndex:indexPath.row withObject:#"Present"];
NSLog(#"Now Present %#",[kidsNames objectAtIndex:(indexPath.row)]);
}
stuID=[kidsID objectAtIndex:indexPath.row];
stuAB=[kidsAbsent objectAtIndex:indexPath.row];
}
- (void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
NSString * ab=[kidsAbsent objectAtIndex:indexPath.row];
static NSString *CellIdentifier = #"myCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"CLICKED!");
if([ab isEqualToString: #"Present"]==1){
[kidsAbsent replaceObjectAtIndex:indexPath.row withObject:#"Absent"];
cell.contentView.backgroundColor = [UIColor redColor];
NSLog(#"Now Absent %#",[kidsNames objectAtIndex:(indexPath.row)]);
}else{
cell.contentView.backgroundColor = [UIColor greenColor];
[kidsAbsent replaceObjectAtIndex:indexPath.row withObject:#"Present"];
NSLog(#"Now Present %#",[kidsNames objectAtIndex:(indexPath.row)]);
}
//send info to the web===============================================================================
stuID=[kidsID objectAtIndex:indexPath.row];
stuAB=[kidsAbsent objectAtIndex:indexPath.row];
}
Try to set cell.backgroundView not cell.contentView.backgroundColor
Or use cell.contentView.backgroundColor but you should note that the backgroundColor must be set in the tableView:willDisplayCell:forRowAtIndexPath: method (from UITableViewCell reference):
- (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];
}
int getIndex = [sharedGameState.selectedValues indexOfObject:[NSNumber numberWithInt:indexPath.row]];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
if(getIndex<21)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}
this is my code when ever i started scrolling the table towards downwards or upwards the first cell which i have checked have loosed the check mark sign, it is just hides all the way.. what is wrong with my code?
Reuse Cell ,
- (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];
int getIndex = [sharedGameState.selectedValues indexOfObject:[NSNumber numberWithInt:indexPath.row]];
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
if(getIndex<21)
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
} // END HERE
cell.textLabel.text = [myArray objectAtIndex:indexPath.row];
return cell;
}
For selecting multiple rows:
- (void)addTableView {
self.tableView = [[UITableView alloc] initWithFrame:CGRectMake("whatever frame you want to set")
style:UITableViewStylePlain];
self.tableView.dataSource = self;
self.tableView.delegate = self;
self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.timeSheetEntryTableView.allowsMultipleSelection = YES;
self.array = [[NSMutableArray alloc]init];
[self.view addSubview:self.tableView];
}
//Cell for row at index path
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *cellIdentifier = #"Cell Identifier";
self.cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (!self.cell) {
self.cell = [[Cell alloc]initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:cellIdentifier];
self.cell.accessoryType = UITableViewCellAccessoryNone;
}
self.cell.selectionStyle = UITableViewCellSelectionStyleNone;
if ([self.array containsObject:indexPath])
{
[self.cell.checkImage setImage:[UIImage imageNamed:#"check_box_selected.png"]];
}
else
{
[self.cell.checkImage setImage:[UIImage imageNamed:#"check_box.png"]];
}
return self.cell;
}
//did select and deselect
// I have used custom cell
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
self.cell = [tableView cellForRowAtIndexPath:indexPath];
[self.array addObject:indexPath];
[self.cell.checkImage setImage:[UIImage imageNamed:#"check_box_selected.png"]];
}
- (void)tableView:(UITableView *)tableView
didDeselectRowAtIndexPath:(NSIndexPath *)indexPath {
self.cell = [tableView cellForRowAtIndexPath:indexPath];
[self.array removeObject:indexPath];
[self.cell.checkImage setImage:[UIImage imageNamed:#"check_box.png"]];
}
I use bellow codes to show data on TableView but when scrolling, data repeat and other data lost.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [FileCompletedArray count];
}
cellForRowatindexpath ():
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UILabel *FileNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 100, 30)];
FileNameLabel.backgroundColor = [UIColor clearColor];
FileNameLabel.font = [UIFont fontWithName:#"Helvetica" size:16];
FileNameLabel.font = [UIFont boldSystemFontOfSize:16];
FileNameLabel.textColor = [UIColor blackColor];
NSLog(#"Reseversed TEMP array %#",FileCompletedArray);
FileNameLabel.text =[FileCompletedArray objectAtIndex:indexPath.row];
[cell.contentView addSubview: FileNameLabel];
[FileNameLabel release];
}
return cell;
}
Do you have any solutions? Thanks in advance
use cell Identifier different
For example like bellow...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = [NSString stringWithFormat:#"%d,%d",indexPath.section,indexPath.row];
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
/// write your code here..
}
}
OR set nil like bellow..
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil] autorelease];
/// write your code here..
}
}
This problem is generated because Your UITableView Reuse Cell instant of create new one.
I give you some suggestion that may be helpful for you.
1) add Controller in between
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
/// Your code of initialization of controller;
}
/// set property of controllers such like (Text UILabel, image of UIImageView...etc) .
return cell;
}
1) Add Your Controller to cell.contentView.
EDITED:
Before You follow my Edited Answer i want to tell you that following code is bad for memory management because it will create new cell for each rows of UITableView, so be careful for it.
But it is better for if UITableView Have Limited row about (50-100 may be ) os use following code if is it suitable for you.
NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d",indexPath.section,indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil)
{
/// Your whole code of controllers;
}
You are setting the text of the label only when creating a new cell. However, during cell reuse, new cell is not created. Hence your code for setting/changing text is not working. You can use this modified code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UILabel *FileNameLabel=nil;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
FileNameLabel = [[UILabel alloc] initWithFrame:CGRectMake(10, 0, 100, 30)];
FileNameLabel.tag = 1001;
FileNameLabel.backgroundColor = [UIColor clearColor];
FileNameLabel.font = [UIFont fontWithName:#"Helvetica" size:16];
FileNameLabel.font = [UIFont boldSystemFontOfSize:16];
FileNameLabel.textColor = [UIColor blackColor];
[cell.contentView addSubview: FileNameLabel];
[FileNameLabel release];
}
if(!FileNameLabel)
FileNameLabel = [cell.contentView viewWithTag:1001];
FileNameLabel.text =[FileCompletedArray objectAtIndex:indexPath.row];
return cell;
}
Alternatively you can use the default textLabel instead of creating and adding new label
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"CellIdentifier";
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
UILabel *FileNameLabel=nil;
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.textLabel.font = [UIFont fontWithName:#"Helvetica" size:16];
cell.textLabel.font = [UIFont boldSystemFontOfSize:16];
cell.textLabel.textColor = [UIColor blackColor];
}
cell.textLabel.text =[FileCompletedArray objectAtIndex:indexPath.row];
return cell;
}
I also faced same problem, the problem occurs when we reuse the cells. At the time of reusing the data is already present in it and we write some more data also, to sort out this, i did a minor change to my table view delegate method cellForRowAtIndexPath. Here the code which i use always using table view.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell"];
if (!cell) {
cell = [[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:#"cell"];
}
for (UIView *view in cell.contentView.subviews) {
[view removeFromSuperview];
}
return cell;
}
The for loop gets executed when we are reusing some cell and what it does is removing all the previous data present in UITableViewCell
Hope this will help someone.
How to select several UITableViewCell (as a checkmark but with my own style) and then do something with selected items?
As a checkmark (or something else) I would like to use UIImageView:
To add to Pandu1251's answer, if you want to use your own check mark image, you can set a custom accessory view and follow the same logic that he has specified.
To set a custom accessory view, use
cell.accessoryView = myAccessoryView; //myAccessoryView is a UIImageView holding your custom check mark image
-(void)tableView:(UITableView *) tableView didSelectRowAtIndexPath: (NSIndexPath *) indexPath
{
UITableViewCell *thisCell = [tableView cellForRowAtIndexPath:indexPath];
if (thisCell.accessoryType == UITableViewCellAccessoryNone)
{
thisCell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
for(int i=0;i<[Array count];i++)
{
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
thisCell.accessoryType = UITableViewCellAccessoryNone;
}
}
Now try this......
Just do as follow. For that you have to take NSMutableArray. i have taken arrMethodsToBeStored here.
- (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];
}
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
cell.textLabel.textColor=[UIColor darkGrayColor];
cell.textLabel.font= [UIFont fontWithName:#"Arial Rounded MT Bold" size:15.0];
Scope_RepairMethod *scpObj=[repairMethodArr objectAtIndex:indexPath.row];
cell.textLabel.text= scpObj.strRepairMethod;
if([self.checkedIndexPath isEqual:indexPath])
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
// NSString *selID;
UITableViewCell *newCell = [tableView cellForRowAtIndexPath:indexPath];
Scope_RepairMethod *scpObj=[repairMethodArr objectAtIndex:indexPath.row];
if (newCell.accessoryType == UITableViewCellAccessoryNone)
{
newCell.accessoryType = UITableViewCellAccessoryCheckmark;
[arrMethodsToBeStored addObject:scpObj.strRepairMethod];
}
else
{
newCell.accessoryType = UITableViewCellAccessoryNone;
[arrMethodsToBeStored removeObject:scpObj.strRepairMethod];
}
NSLog(#"selected method arr==== %#",arrMethodsToBeStored);
// I want to enable my save button only if one or more values from table are selected
if(arrMethodsToBeStored.count > 0)
saveBtn.enabled=true;
else
{
saveBtn.enabled=false;
}
}
