tableview cell value - iphone

I am making an iphone application. In one of the view of the application I have implemented the table view. On each table view cell I have put one or two buttons. Now I want that whenever I click the button it give me the value of cell. How can I do it if anybody has an idea about this please let me know.
The code which I have implemented to display the button is:
- (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];
}
cell.textLabel.text = [rangetime objectAtIndex:indexPath.row];
NSString *checkstatus = [finalstatusarray objectAtIndex:indexPath.row];
if ([checkstatus isEqualToString:#"YES" ])
{
UIButton *submitbutton1 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton1.tag=1;
submitbutton1.frame = CGRectMake(200, 4, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"yes.png"];
[submitbutton1 setImage:btnImage1 forState:UIControlStateNormal];
cell.accessoryView = submitbutton1;
[submitbutton1 addTarget:self action:#selector(updatestatus) forControlEvents:UIControlEventTouchUpInside];
}
else if ([checkstatus isEqualToString:#"NO" ])
{
UIButton *submitbutton2 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton2.tag = 2;
submitbutton2.frame = CGRectMake(200, 4, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"no.png"];
[submitbutton2 setImage:btnImage1 forState:UIControlStateNormal];
[submitbutton2 addTarget:self action:#selector(updatestatus) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = submitbutton2;
}
else if ([checkstatus isEqualToString:#"s" ])
{
UIButton *submitbutton1 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton1.tag = 1;
submitbutton1.frame = CGRectMake(255, 5, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"no.png"];
[submitbutton1 setImage:btnImage1 forState:UIControlStateNormal];
[cell addSubview:submitbutton1];// = submitbutton1;
[submitbutton1 addTarget:self action:#selector(updatestatus) forControlEvents:UIControlEventTouchUpInside];
UIButton *submitbutton2 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton2.tag = 2;
submitbutton2.frame = CGRectMake(285, 5, 28, 29);
UIImage * btnImage2 = [UIImage imageNamed:#"yes.png"];
[submitbutton2 setImage:btnImage2 forState:UIControlStateNormal];
[cell addSubview:submitbutton2];
[submitbutton2 addTarget:self action:#selector(updatestatus) forControlEvents:UIControlEventTouchUpInside];
}
return cell;
}
Thanku very much.

You can do with the help of following code.
I had edited your answer in target method of UIButton and added event as argument so you can get indexPath of the row.
- (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];
}
cell.textLabel.text = [rangetime objectAtIndex:indexPath.row];
NSString *checkstatus = [finalstatusarray objectAtIndex:indexPath.row];
if ([checkstatus isEqualToString:#"YES" ])
{
UIButton *submitbutton1 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton1.tag=1;
submitbutton1.frame = CGRectMake(200, 4, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"yes.png"];
[submitbutton1 setImage:btnImage1 forState:UIControlStateNormal];
cell.accessoryView = submitbutton1;
[submitbutton1 addTarget:self action:#selector(updatestatus:event:) forControlEvents:UIControlEventTouchUpInside];
}
else if ([checkstatus isEqualToString:#"NO" ])
{
UIButton *submitbutton2 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton2.tag = 2;
submitbutton2.frame = CGRectMake(200, 4, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"no.png"];
[submitbutton2 setImage:btnImage1 forState:UIControlStateNormal];
[submitbutton2 addTarget:self action:#selector(updatestatus:event:) forControlEvents:UIControlEventTouchUpInside];
cell.accessoryView = submitbutton2;
}
else if ([checkstatus isEqualToString:#"s" ])
{
UIButton *submitbutton1 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton1.tag = 1;
submitbutton1.frame = CGRectMake(255, 5, 28, 29);
UIImage * btnImage1 = [UIImage imageNamed:#"no.png"];
[submitbutton1 setImage:btnImage1 forState:UIControlStateNormal];
[cell addSubview:submitbutton1];// = submitbutton1;
[submitbutton1 addTarget:self action:#selector(updatestatus:event:) forControlEvents:UIControlEventTouchUpInside];
UIButton *submitbutton2 = [UIButton buttonWithType:UIButtonTypeCustom];
submitbutton2.tag = 2;
submitbutton2.frame = CGRectMake(285, 5, 28, 29);
UIImage * btnImage2 = [UIImage imageNamed:#"yes.png"];
[submitbutton2 setImage:btnImage2 forState:UIControlStateNormal];
[cell addSubview:submitbutton2];
[submitbutton2 addTarget:self action:#selector(updatestatus:event:) forControlEvents:UIControlEventTouchUpInside];
}
return cell;
}
- (void)updatestatus:(id)sender event:(UIEvent *)event
{
NSIndexPath *indexPath = [tblCityList indexPathForRowAtPoint:[[[event
touchesForView:sender] anyObject] locationInView:YourTableName]];
**Now You can access the row value with the help of indexPath.row**
}

First of all, you have to modify the below code...
[submitbutton1 addTarget:self action:#selector(updatestatus:) forControlEvents:UIControlEventTouchUpInside];
Instead of,
[submitbutton1 addTarget:self action:#selector(updatestatus) forControlEvents:UIControlEventTouchUpInside];
And write the following code in updatestatus:
- (IBAction) updatestatus:(id)sender
{
UIButton *btn = (UIButton*) sender;
UITableViewCell *cellSelected = (UITableViewCell*) [btn superview];
NSIndexPath *idxPath = [tableView indexPathForCell:cell];
// Your code...
}

Have the following code
-(void)showCellValue:(UIControl *)button{
UITableViewCell *cell = (UITableViewCell*)button.superview;
NSIndexPath *indexPath =[aTableView indexPathForCell:cell];
NSLog(#"The cell value is %#",[tableData objectAtIndex:indexPath.row]);
}
Assign this method showCellValue to the selector of the button. tableData is the array from which u load the data to the table. And in ur case it s rangeTime array
Hope this helps.

UITabel View Cell Button Mixed Up

In my table View Cell Each Cell Has two Button as, Edit And Cancel, On click Of Edit at The Same time Cancel Button Should Change. My Problem Is When I Try To click Edit Button Another cell cancel button image was changed not on that cell which i clicked?
Here Is My Code----
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"MenuNameCell";
MenuNameCell *cell = (MenuNameCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MenuNameCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
_checkButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_checkButton setFrame:CGRectMake(232, 13, 25, 28)];
[_checkButton setBackgroundImage:[UIImage imageNamed:#"edit.png"]forState:UIControlStateNormal];
[_checkButton addTarget:self action:#selector(editQuantity:) forControlEvents:UIControlEventTouchUpInside];
//_checkButton.tag = 0;
[cell.contentView addSubview:_checkButton];
// Creating Button For CANCEL Order
_cancelButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_cancelButton setFrame:CGRectMake(265, 13, 25, 28)];
[_cancelButton setBackgroundImage:[UIImage imageNamed:#"cancel.png"] forState:UIControlStateNormal];
[_cancelButton addTarget:self action:#selector(cancelOreder:) forControlEvents:UIControlEventTouchUpInside];
// _cancelButton.tag = 1;
_textFieldQuantity = [[UITextField alloc] initWithFrame:CGRectMake(125,14,42,21)];
_textFieldQuantity.userInteractionEnabled = NO;
[cell addSubview:_cancelButton];
[cell addSubview:_textFieldQuantity];
} else {
cell._nameLabel = (UILabel *)[cell.contentView viewWithTag:0];
cell._amountMenu = (UILabel *)[cell.contentView viewWithTag:1];
}
[_checkButton setTag:indexPath.row];
[_cancelButton setTag:indexPath.row];
cell._nameLabel.text = [_hotel._orderedMenus objectAtIndex:indexPath.row];
cell._amountMenu.text = [[_hotel._menuPrices objectAtIndex:indexPath.row] stringValue];
_textFieldQuantity.text = [[_hotel._selectedQuantity objectAtIndex:indexPath.row] stringValue];
return cell;
}
Thanks In Advance!!
For each cell button, give the tag of the current indexPath.row for ex:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"MenuNameCell";
MenuNameCell *cell = (MenuNameCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"MenuNameCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
_checkButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_checkButton setFrame:CGRectMake(232, 13, 25, 28)];
[_checkButton setBackgroundImage:[UIImage imageNamed:#"edit.png"]forState:UIControlStateNormal];
[_checkButton addTarget:self action:#selector(editQuantity:) forControlEvents:UIControlEventTouchUpInside];
_checkButton.tag = [NSString stringWithFormat:#"5%d",indexPath.row];
[cell.contentView addSubview:_checkButton];
// Creating Button For CANCEL Order
_cancelButton = [UIButton buttonWithType:UIButtonTypeCustom];
[_cancelButton setFrame:CGRectMake(265, 13, 25, 28)];
[_cancelButton setBackgroundImage:[UIImage imageNamed:#"cancel.png"] forState:UIControlStateNormal];
[_cancelButton addTarget:self action:#selector(cancelOreder:) forControlEvents:UIControlEventTouchUpInside];
_cancelButton.tag = [NSString stringWithFormat:#"6%d",indexPath.row];
_textFieldQuantity = [[UITextField alloc] initWithFrame:CGRectMake(125,14,42,21)];
_textFieldQuantity.userInteractionEnabled = NO;
[cell addSubview:_cancelButton];
[cell addSubview:_textFieldQuantity];
} else {
cell._nameLabel = (UILabel *)[cell.contentView viewWithTag:[NSString stringWithFormat:#"5%d",indexPath.row]];
cell._amountMenu = (UILabel *)[cell.contentView viewWithTag:[NSString stringWithFormat:#"6%d",indexPath.row]];
}
cell._nameLabel.text = [_hotel._orderedMenus objectAtIndex:indexPath.row];
cell._amountMenu.text = [[_hotel._menuPrices objectAtIndex:indexPath.row] stringValue];
_textFieldQuantity.text = [[_hotel._selectedQuantity objectAtIndex:indexPath.row] stringValue];
return cell;
}

How to pass change the toggle button through indexpath of tableview in iPhone?

I have a tableview where I am displaying my values from database in tableview cells. In this tableview cellforrowatindexpath, I have created a button with an image on it and set selector for it. So when I click on the button my selector is called and it changes my image to another image.
But the problem is it does not identifies the indexpath i.e. if 4 rows are present in the tableview and if I click on the first row button, its image should change but problem is 4th row action is performed and its image is changed because it does not get the proper indexpath of the image to change.
This is my cellforrowatindexpath code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"Cell%d%d", indexPath.section, indexPath.row];
appDelegate = (StopSnoozeAppDelegate*)[[UIApplication sharedApplication]delegate];
cell =(TAlarmCell *) [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[TAlarmCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 20, 20, 20);
mimageButton.tag = 1;
onButtonView = [[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 30, 50)];
onButtonView.tag = 2;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType::) forControlEvents:UIControlEventTouchUpInside];
}
return cell;
}
This is my changemapType code
-(void)changeMapType:(NSIndexPath*)path1:(UIButton*)sender{
appDelegate.changeimagetype =!appDelegate.changeimagetype;
if(appDelegate.changeimagetype == YES)
{
onButtonView.image = [UIImage imageNamed:#"alarm_OF.png"];
[mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
appDelegate.changeimagetype = YES;
}
else
{
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
appDelegate.changeimagetype = NO;
}
}
Don't break table view cell reuse just to put a different tag on each button. If your cells are the same, use the same reuse identifier.
You can find out the index path of the sender like this, without any need to mess around with tags. It also works for multi section tables.
CGPoint hitPoint = [sender convertPoint:CGPointZero toView:self.tableView];
NSIndexPath *hitIndex = [self.tableView indexPathForRowAtPoint:hitPoint];
I don't think you can have additional arguments in an #selector like that. What you might have to do is subclass UIButton and add an NSIndexPath property (or even just an int) and in -(void)changeMapType:(MyCustomButton*)sender access the property there.
Also it seems you do not even use the index path in changeMapType so that will need to be changed as well.
EDIT: Is it the button image you are trying to change? In which case you don't need the index path at all, or a subclass. Just use [sender setImage:(UIImage *)image forState:(UIControlState)state].
Use yourTableView for getting the Index Path.. Try something like this.
- (void)buttonAction:(UIButton*)sender {
UITableViewCell *cell = (UITableViewCell*)button.superview;
NSIndexPath *indexPath = [yourTableView indexPathForCell:cell];
NSLog(#"%d",indexPath.row)
}
I think following code might help you..
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UIView *myCheckbox = [[UIView alloc] init];
UIButton *myBt1 = [[UIButton alloc] initWithFrame:CGRectMake(10, 10, 30, 30)];
if([appDelegate.changeimagetype == YES"]){
[myBt1 setBackgroundImage:[UIImage imageNamed:#"alarm_ON.png"] forState:UIControlStateNormal];
}
else {
[myBt1 setBackgroundImage:[UIImage imageNamed:#"alarm_OF.png"] forState:UIControlStateNormal];
}
[myBt1 addTarget:self action:#selector(btcheckbox:) forControlEvents:UIControlEventTouchDown];
[myBt1 setTag:indexPath.row];
[myCheckbox addSubview:myBt1];
[myBt1 release];
[myCheckbox release];
[cell addsubview:myview];
return cell;
}
-(void) btcheckbox:(id) sender
{
UIButton *currentButton = (UIButton *) sender;
if([[currentButton backgroundImageForState:UIControlStateNormal] isEqual:[UIImage imageNamed:#"alarm_OF.png"]])

appDelegate.changeimagetype = YES;

i am trying this but not working.it change all row value
You only have one instance of the totalItem. If you have many rows and you want to store each one individually, you will need to create an array to store each of the individual rows and then display the appropriate value in the cellForRow method.
I've done it.
- (IBAction)plusAction:(id)sender{
int correctIndex = [sender tag];
int old = [[appDelegate.quantityArray objectAtIndex:correctIndex] intValue];
[appDelegate.quantityArray replaceObjectAtIndex:correctIndex withObject:[NSNumber numberWithInt:old + 1]];
[menuTableView reloadData];
}
- (IBAction)minusAction:(id)sender{
int correctIndex = [sender tag];
int old = [[appDelegate.quantityArray objectAtIndex:correctIndex] intValue];
[appDelegate.quantityArray replaceObjectAtIndex:correctIndex withObject:[NSNumber numberWithInt:old - 1]];
[menuTableView reloadData];
}

how to set image on cell through togglebutton in iphone

Hi I try this code but it not show image on cell where i am wrong i want when i click every cell then i want to display image or when i scroll cell then image not disappear it should be appear on that cell i use this code but it not working pease help me on this.
#interface imageclass : UITableViewController
{
BOOL changeimagetype;
//UIImage *btnImage;
UIButton *mimageButton;
UIImageView *onButtonView;
}
#property (nonatomic,retain)UIImageView *onButtonView;
#property BOOL changeimagetype;
#property (nonatomic,retain)UIButton *mimageButton;
-(void)changeMapType:(id)sender;
#end
#import "imageclass.h"
#implementation imageclass
#synthesize onButtonView,changeimagetype,mimageButton;
-(void)changeMapType:(id)sender
{

[mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
//someBarButtonItem.image = [UIImage imageNamed:#"alarm_ON..png"];
//changeimagetype =NO;
}
else
{
//self.myGreatMapView.mapType = MKMapTypeSatellite;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setImage:onButtonView.image forState:UIControlStateNormal];
}
}
- (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];
}
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
onButtonView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 50)];
onButtonView.tag = 2;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setBackgroundImage:[onButtonView.image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
[onButtonView release];
// Configure the cell...
return cell;
}
Define you tableview delegate like this.
- (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];
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
onButtonView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 30, 50)];
onButtonView.tag = 2;
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
[mimageButton setBackgroundImage:[onButtonView.image stretchableImageWithLeftCapWidth:0.0 topCapHeight:0.0] forState:UIControlStateNormal];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
[onButtonView release];
}
// Configure the cell...
return cell;
}
Here is the code:-
Add this in cellForRowAtIndexPath method. And also set flag variable in your target method for togglebutton.
if(flagButton)
{
onButtonView.image = [UIImage imageNamed:#"alarm_ON.png"];
}
else
{
onButtonView.image = [UIImage imageNamed:#"alarm_OFF.png"];
}
I tried this different approach, and it worked.
While configuring the button,
- (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];
mimageButton = [UIButton buttonWithType:UIButtonTypeCustom];
mimageButton.frame=CGRectMake(10, 10, 30, 50);
mimageButton.tag = 1;
[tempButton setImage:[UIImage imageNamed:#"alarm_ON.png"] forState:UIControlStateNormal];
[tempButton setImage:[UIImage imageNamed:#"alarm_OF.png"] forState:UIControlStateSelected];
[cell.contentView addSubview:mimageButton];
[mimageButton addTarget:self action:#selector(changeMapType:) forControlEvents: UIControlEventTouchUpInside];
}
// Configure the cell...
return cell;
}
And in changeMapType: method,
-(void)changeMapType:(id)sender{
changeimagetype =!changeimagetype;
sender.selected = changeimagetype;
}

}enter code here
NSInteger section = indexPath.section;
NSInteger row = indexPath.row;
//int row = button.tag;
NSLog(#"SECTION IS:%d",section);
NSLog(#"ROW IS: %d",row);

NSLog(#"NUMBER OF OBJECTS: %d",[array count]);
UIButton *test = (UIButton *)[array objectAtIndex:2];
[test setBackgroundImage:[UIImage imageNamed:#"thumbsdown_not_selected.png"]forState:UIControlStateNormal];
}
Due to issue with tag of button while I change image of one button several buttons are changing.
If any one can please find a solution it will be helpful.... tag is setting for buttons in sections which we can view.
If the Tableview is not sectioned its working well.
Your problem might be the fact that you're setting the variable only if the cell is newly created. Perhaps the sectioning has an impact on how many cells are affected. Try pulling your thumbs up / thumbs down code out of the if (cell == nil) block and see if that has an effect.
