I have UITableView with custom table row. What I need is to have possibility to reorder rows. so in ViewDidLoad i add:
- (void)viewDidLoad {
[super viewDidLoad];
[self.myTableView setEditing: YES animated: YES];
}
also add next methods:
- (BOOL)tableView:(UITableView *)tableView
canEditRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView
editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath {
return UITableViewCellEditingStyleNone;
}
- (BOOL)tableView:(UITableView *)tableView
shouldIndentWhileEditingRowAtIndexPath:(NSIndexPath *)indexPath {
return NO;
}
- (BOOL)tableView:(UITableView *)tableView
canMoveRowAtIndexPath:(NSIndexPath *)indexPath {
return YES;
}
Also I set bg color for my custom table row:
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *customTableRow = #"customTableRow";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:
customTableRow];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"customTableRow"
owner:self options:nil];
if (nib.count > 0) {
cell = self.customTableRow;
}
}
cell.contentView.backgroundColor = [UIColor colorWithRed:(228.0f/255.0f)
green:237.0f/255.0f blue:244.0f/255.0f alpha:1.0];
return cell;
}
And then I run my app and I had an unexpected view:
So I have tow questions:
1.So why it so ? Reorder button is not transparent ??
2.How to change that button to my on image ??
The problem is that you're changing the background color of the contentView. Have you tried changing the background color of the cell itself in -tableView:willDisplayCell: forRowAtIndexPath:?

I have UITableview
uitableview containe playlist audio song and i put a button in cell.
User click on the row audio start to play
i want , when user click on row only button should be enable while cell should be disable
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSURL *url = [[NSURL alloc]initFileURLWithPath:soundsPath];
NSURL * playurl =[NSURL URLWithString:[passarray objectAtIndex:indexPath.row] relativeToURL:url];
if (indexPath.row ==1) {
buybtn.userInteractionEnabled=YES;
cell.contentView.userInteractionEnabled=YES;
buybtn.showsTouchWhenHighlighted=YES;
}
player = [[AVAudioPlayer alloc] initWithContentsOfURL:playurl error:nil];
[self.player play];
player.delegate = self;
cell =[tableView cellForRowAtIndexPath:indexPath];
cellText = cell.textLabel.text;
lbl.text=cellText;
}
In method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
assign a tag to that button which you need to access as : buybtn.tag = YOUR_TAG
and then in didselectrow method :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell =[tableView cellForRowAtIndexPath:indexPath];
NSLog(#"sunviews : %#",cell.subviews);
for (UIView *_view in cell.subviews) {
if (_view.tag != YOUR_TAG) {
[_view setUserInteractionEnabled:NO];
}
}
}
Hope it helps you.
This might help: Add these code in UITableView's didSelectRowAtIndexPath: method
Add tag to specific button say 99 then
for(UIView *subview in cell.subView)
{
if(![subview isKindOfClass:[UIButton class])
{
subview.userInteractionEnabled = NO;
}
else
{
UIButton *btn = (UIButton *)subview;
if(btn.tag != 99)
btn.userInteractionEnabled = NO;
}
}
EDIT : A specific button to be enabled from other buttons.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(indexPath.row == sepicificRowNumber){
buybtn.userInteractionEnabled=YES;
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
if(indexPath.row == sepicificRowNumber){
//Nothing happen on click
}
}
Hope it helps.
I Have a table view with multiple sections as follows..
I know how to set background color for the selecting a Cell / row
But i need to fill the selection to the entire section instead of individual cell selections
is it possible if yes how any solution
i hope its working....
- (NSIndexPath *)tableView:(UITableView *)tableView willSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NSIndexPath *currentSelectedIndexPath = [tableView indexPathForSelectedRow];
if (currentSelectedIndexPath != nil)
{
[[tableView cellForRowAtIndexPath:currentSelectedIndexPath] setBackgroundColor:NotSelectedCellBGColor];
}
return indexPath;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[[tableView cellForRowAtIndexPath:indexPath] setBackgroundColor:SelectedCellBGColor];
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (cell.isSelected == YES)
{
[cell setBackgroundColor:SelectedCellBGColor];
}
else
{
[cell setBackgroundColor:setBackgroundColor:NotSelectedCellBGColor];
}
}
Pass the section value from the didSelectRowAtIndexPath delegate of tableview and change the background color of the cell in cellForRowAtIndexPath dataSource method of UITableview
in Header File
NSUInteger index;
in Implemention File (.m)
-(void) viewDidLoad{
index=-1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"CELL_IDENTIFIER";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if (indexPath.section==index) {
cell.contentView.backgroundColor=[UIColor yellowColor];
}
else{
cell.contentView.backgroundColor=[UIColor clearColor];
}
cell.textLabel.text=[NSString stringWithFormat:#"Row %d Section %d",indexPath.row,indexPath.section];
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
index=indexPath.section;
[tableView reloadData];
}
.h
int currentSection;
.m
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
currentSection = indexPath.section;
[tableView reloadData];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if ( currentSection == indexPath.section ) {
cell.backgroundColor = SelectedColor;
} else {
cell.backgroundColor = OtherColor;
}
}
i have 2 views-view1 and view2, one for entering data and another for displaying the entered data.
I am able to display the entered data in view2 in labels. But how to display the data in a UITableView. Following is my code to display the data:
view2.m
#synthesize details; //details is an object of NSMutableArray.
- (void)viewWillAppear:(BOOL)animated {
[super viewWillAppear:animated];
textLabel.text = self.name;
lblCity.text = self.city;
lblGender.text = self.gender;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [details count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [details objectAtIndex:indexPath.row];
//cell.imageView.image = [UIImage imageNamed:#"creme_brelee.jpg"];
return cell;
i debuuged and found that cellForRowAtIndexPath is never called.
Where am i getting wrong? How do i solve it?
You need to create a NSMutableArray of display Data in to UITableViewCell like below and don't forget to declare UITableView delegates in .h file <UITableViewDataSource,UITableViewDelegate> and also connect your UITableView IBOutlet in your xib and also connect the delegate:
- (void)viewDidLoad
{
[super viewDidLoad];
arrCategorisation=[[NSMutableArray alloc] initWithObjects:#"DataOne",#"DataTwo",#"DataThree", #"DataFour",#"DataFive",nil];
}
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return arrCategorisation.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier =[NSString stringWithFormat:#"%d",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
cell.textLabel.text=[arrCategorisation objectAtIndex:indexPath.row];
}
// Configure the cell...
return cell;
}
#pragma mark - Table view delegate
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
your Table load data like:-
In my app, You can tap a cell, and it brings up a new view. You can edit the tableviewCell's textLabel, and save it. But when you switch views and come back to the tableView, the cells are in a different order. What could be the reason for this?
Here is my Code:
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString * identifier = #"identifier";
self.cell = [tableView dequeueReusableCellWithIdentifier:identifier];
h = [self.tableArray objectAtIndex:indexPath.row];
NSString *brandModel = [[h.brand stringByAppendingString:#" "] stringByAppendingString:h.model];
self.cell.mainLabel.text = brandModel;
self.cell.nicknameLabel.text = handguns.nickname;
return self.cell;
}
If you are reloading tableView after saving UITableView cell then It will be reordered as initial because array from which you are setting cell data is as it is.You can change only table View cells not array data position in an array.
Below I have written a UITableView code to move cells and it is working fine after pushing view.If I remove reload method from viewWillAppear:
#import "MoveCellViewController.h"
#interface MoveCellViewController ()
#end
#implementation MoveCellViewController
- (void)viewDidLoad
{
UIBarButtonItem *left=[[UIBarButtonItem alloc] initWithTitle:#"Edit" style:UIBarButtonItemStyleBordered target:self action:#selector(edit)];
self.navigationItem.leftBarButtonItem=left;
myArray=[[NSMutableArray alloc]init]; //mutable array;
myArray=[NSMutableArray arrayWithObjects:#"Aman",#"Ankit",#"Sumit",#"Hercules",#"Jackie Chan", nil];
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
}
-(void)edit
{
if (self.navigationItem.leftBarButtonItem.title==#"Edit") {
self.navigationItem.leftBarButtonItem.title=#"Done";
[_tableView setEditing:YES];
}else
{
[_tableView setEditing:NO];
self.navigationItem.leftBarButtonItem.title=#"Edit";
}
}
- (void)didReceiveMemoryWarning
{
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [myArray count];
}
// Row display. Implementers should *always* try to reuse cells by setting each cell's reuseIdentifier and querying for available reusable cells with dequeueReusableCellWithIdentifier:
// Cell gets various attributes set automatically based on table (separators) and data source (accessory views, editing controls)
- (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];
}
cell.userInteractionEnabled=YES;
cell.textLabel.text=[myArray objectAtIndex:indexPath.row];
return cell;
}
- (BOOL)tableView:(UITableView *)tableView canMoveRowAtIndexPath:(NSIndexPath *)indexPath
{
return YES;
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return UITableViewCellEditingStyleNone;
}
- (void)tableView:(UITableView *)tableView moveRowAtIndexPath:(NSIndexPath *)sourceIndexPath toIndexPath:(NSIndexPath *)destinationIndexPath{
id ob = [myArray objectAtIndex:destinationIndexPath.row];
[myArray replaceObjectAtIndex:destinationIndexPath.row withObject:[myArray objectAtIndex:sourceIndexPath.row]];
[myArray replaceObjectAtIndex:sourceIndexPath.row withObject:ob];
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
NextViewController *nx=[[NextViewController alloc] init];
[self.navigationController pushViewController:nx animated:YES];
}
#end
This is working code and will not change after push view controller.
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *CellIdentifier = [NSString stringWithFormat:#"S%1dR%1d",indexPath.section,indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:CellIdentifier];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
}
h = [self.tableArray objectAtIndex:indexPath.row];
NSString *brandModel = [[h.brand stringByAppendingString:#" "] stringByAppendingString:h.model];
self.cell.mainLabel.text = brandModel;
self.cell.nicknameLabel.text = handguns.nickname;
return self.cell;
}
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue2 reuseIdentifier:nil];
}
Write rest of the code here

After searching all over internet for a long time, but not getting the appropriate answer. I am putting the UITableView in editing mode and selecting multiple rows at a time. It is working great, but I wanted to change the color of checkmark from red to blue same as it is in the iPhone email app.
Any help would be appreciated.
Edited Version:
Here is my code...
in my ViewDidLoad function:
- (void)viewDidLoad
{
...
[deviceTableVIew setAllowsSelectionDuringEditing:YES];
[deviceTableVIew setAllowsMultipleSelectionDuringEditing:YES];
[super viewDidLoad];
}
I have two UIButtons whhich set the editing mode for the tableview as follows:
-(IBAction)control:(id)sender{
btnControl.enabled = false;
btnControl.hidden = true;
btnCancel.enabled = true;
btnCancel.hidden = false;
stateToggleToolbar.hidden = false;
[self.deviceTableVIew setEditing:YES animated:YES];
}
-(IBAction)cancel:(id)sender{
btnCancel.enabled = false;
btnCancel.hidden = true;
btnControl.enabled = true;
btnControl.hidden = false;
stateToggleToolbar.hidden = true;
[self.deviceTableVIew setEditing:NO animated:YES];
}
The UITableView delegate methods are:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
//setting up the cells here
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
...
if ([tableView isEditing] == YES) {
// Do Nothing
}else{
[self.navigationController pushViewController:viewController animated:YES];
}
}
-(void) tableView:(UITableView *)tableView commitEditingStyle:(UITableViewCellEditingStyle)editingStyle forRowAtIndexPath:(NSIndexPath *)indexPath{
}
- (UITableViewCellEditingStyle)tableView:(UITableView *)tableView editingStyleForRowAtIndexPath:(NSIndexPath *)indexPath{
return 3;
}
One line solution is here)
Just set cell tintColor in your cellForRow:atIndexPath method.
cell.tintColor = UIColor.red
Below is swift code:
func tableView(tableView: UITableView,
cellForRowAtIndexPath indexPath: NSIndexPath)
-> UITableViewCell
{
//get cell to configure from tableView
let cell = tableView.dequeueReusableCellWithIdentifier("myCellIdentifier", forIndexPath: indexPath) as UITableViewCell
//This line will change checkmark color of your awesome cell
cell.tintColor = UIColor.redColor()
// Configure cell
// ...
//work is done! Let put the cell back to the tableView))
return cell
}
And this is the result of selected and not selected cells::
You cant change checkmark color as its not supported.The thing which you can do is make an image and add following code in your cellForRowAtIndexPath
- (void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
selected=[[NSMutableArray alloc] init];
for(int i=0;i<10;i++){
[selected addObject:#"0"];
}
}
- (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.textLabel.text=[NSString stringWithFormat:#"hello %d",indexPath.row];
if([[selected objectAtIndex:indexPath.row] isEqualToString:#"1"]){
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
else{
cell.accessoryType=UITableViewCellAccessoryNone;
}
// Configure the cell...
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if([[selected objectAtIndex:indexPath.row] isEqualToString:#"0"]){
[selected replaceObjectAtIndex:indexPath.row withObject:#"1"];
}
else{
[selected replaceObjectAtIndex:indexPath.row withObject:#"0"];
}
[tbl reloadData];
}
You can change the checkmark image. Create check mark image with check mark image and color.
Then replace image name in the below code. This works fine for iOS 6 and below
- (void)setSelected:(BOOL)selected animated:(BOOL)animated
{
[super setSelected:selected animated:animated];
if (self.isEditing) {
if (selected){
for (UIView *subview in self.subviews) {
if ([NSStringFromClass([subview class]) isEqualToString:#"UITableViewCellEditControl"]) {
for (UIView *aView in subview.subviews) {
if ([NSStringFromClass([subview class]) isEqualToString:#"UITableViewCellEditControl"]) {
[aView.layer setContents:(id)[UIImage imageNamed:#"delete_check.png"].CGImage];
}
}
}
}
}
}
}
