I have two radio buttons on UITableView Cell.I am able to select one of them while scrolling UITableView down but when I scroll tableview up all radio buttons get unselected. After scrolling also I want to keep them selected but I am not able to do that....So please anyone having solution help me. Thank you

You have created only one leftTickBtn and rightTickBtn and updated it each time when row is created. So finally whatever you have done with radio button, its affected to only last button.
Update your code as below :
UIButton *leftBtnclick = [UIButton buttonWithType:UIButtonTypeCustom];
leftBtnclick.tag=999+indexPath.row;
UIButton *rightBtnclick = [UIButton buttonWithType:UIButtonTypeCustom];
rightBtnclick.tag=1000+indexPath.row;
And implement methods like :
- (IBAction)leftTickBtnClicked:(UIButton *)sender
{
sender.selected = TRUE;
UITableViewCell *cell = [tblAppointment cellForRowAtIndexPath:[NSIndexPath indexPathForRow:1000-sender.tag inSection:0]];
for (id view in cell.contentView.subviews)
{
if ([view isKindOfClass:[UIButton class]])
{
// your code
UIButton *btnRight = (UIButton *)view;
if (sender.selected == TRUE)
btnRight.selected = FALSE;
else
btnRight.selected = TRUE;
}
}
}
And
- (IBAction)rightTickBtnClicked:(UIButton *)sender
{
sender.selected = TRUE;
UITableViewCell *cell = [tblAppointment cellForRowAtIndexPath:[NSIndexPath indexPathForRow:999-sender.tag inSection:0]];
for (id view in cell.contentView.subviews)
{
if ([view isKindOfClass:[UIButton class]])
{
// your code
UIButton *btnLeft = (UIButton *)view;
if (sender.selected == TRUE)
btnLeft.selected = FALSE;
else
btnLeft.selected = TRUE;
}
}
}
You have this issue because of how the reusable cell works.
When you scroll away from the cell you made changes on the radio button , and then try to scroll back to that specific row ,a reusable cell dequeueReusableCellWithIdentifier does not guarantee that it will dequeue the exact same cell you made the changes and most likely it will dequeue a cell that you have not made any changes
You will need to keep track of the buttons selections in a List outside cellForRowAtIndexPath and reassign the selections to your radio buttons in cellForRowAtIndexPath much like the same idea with assigning the cell text every time with cell.numberLbl.text = [numberArray objectAtIndex:indexPath.row]; by using the indexPath.row in an array
See modification [1] , [2] and [3] on the code below (haven't tested it but you get the idea)
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
customCell *cell = (customCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"customCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
leftBtnclick = [UIButton buttonWithType:UIButtonTypeCustom];
leftBtnclick.tag=999;
[leftBtnclick setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
[leftBtnclick setImage:[UIImage imageNamed:#"checked.png"] forState:UIControlStateSelected];
if (screenHeight == 667)
{
[leftBtnclick setFrame:CGRectMake(50, 59, 30, 30)];
}
else if(screenHeight == 480)
{
[leftBtnclick setFrame:CGRectMake(50, 40, 30, 30)];
}
[leftBtnclick addTarget:self action:#selector(leftTickBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.leftOptBtn addTarget:self action:#selector(leftTickBtnClicked:) forControlEvents:UIControlEventTouchUpInside];

[rightBtnclick setFrame:CGRectMake(180, 59, 30, 30)];
}
else if(screenHeight == 480)
{

}

//[1]Set values for left and right

}
//[2]Update RightTickArray At Pos
[RightTickArray objectAtIndex:indexPath.row] = leftTickBtn.selected;
}
}
}
-(void)rightTickBtnClicked:(id)sender

I got solution for my question. UITableView cells are reusable when you scroll tableview cell gets reused that's why radio button selection disappears. So solution is store your selection in one array use that array in cellForRowAtIndexPath. See code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
customCell *cell = (customCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"customCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
leftBtnclick = [UIButton buttonWithType:UIButtonTypeCustom];
leftBtnclick.tag=999;
cell.leftOptBtn.tag=999;
[leftBtnclick setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
[leftBtnclick setImage:[UIImage imageNamed:#"checked.png"] forState:UIControlStateSelected];
[leftBtnclick setFrame:CGRectMake(50, 59, 30, 30)];
[leftBtnclick addTarget:self action:#selector(leftTickBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.leftOptBtn addTarget:self action:#selector(leftBtnClicked) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:leftBtnclick];
rightBtnclick = [UIButton buttonWithType:UIButtonTypeCustom];
rightBtnclick.tag=1000;
cell.rightTickBtn.tag=1000;
[rightBtnclick setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
[rightBtnclick setImage:[UIImage imageNamed:#"checked.png"] forState:UIControlStateSelected];
[rightBtnclick setFrame:CGRectMake(190, 59, 30, 30)];

if ([[answerArray objectAtIndex:indexPath.row] isEqualToString:#"YES"])

UITable view is working fine. when scrolling checked image is changed to uncheck. And also i need to take the particular checked image data in SAVE button Action.Can any body help me to solve this problem in prj.

Take one array which is Use to store IndexValue of Selected button,
#property (nonatomic,retain) NSMutableArray *arySelected;
Initialize array in ViewDidLoad,
- (void)viewDidLoad {
[super viewDidLoad];
self.arySelected = [[NSMutableArray alloc] init];
}
Change Code of TableViewCell Delegate,
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.backgroundColor = [UIColor clearColor];
cell.selectionStyle= UITableViewCellSelectionStyleNone;
}
UIButton *btn = [[UIButton alloc]initWithFrame:CGRectMake(10,10, 20, 20)];
if (![arySelected containsObject:[NSString stringWithFormat:#"%ld",(long)indexPath.row]])
{
[btn setImage:[UIImage imageNamed: #"checked.png"] forState:UIControlStateSelected];
}
else
{
[btn setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
}
btn.tag=indexPath.row;
[btn addTarget:self action:#selector(checkBoxClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:btn];
UILabel *lbl_name =[[UILabel alloc]initWithFrame:CGRectMake(35, 10, 100, 20)];
lbl_name.text=[NSString stringWithFormat:#"%#",[[arr1 valueForKey:#"Name"]objectAtIndex:indexPath.row]];
lbl_name.tag=5;
lbl_name.textColor=[UIColor blackColor];
[lbl_name setTextAlignment:NSTextAlignmentCenter];
lbl_name.font=[UIFont systemFontOfSize:15];
[cell addSubview:lbl_name];
return cell;
}
// On your button Event,
-(void)checkBoxClicked:(id)sender
{
sender.selected = ! sender.selected;
if (sender.selected)
{
[arySelected addObject:[NSString stringWithFormat:#"%ld",(long)sender.tag]];
}
else
{
[arySelected removeObject:[NSString stringWithFormat:#"%ld",(long)sender.tag]];
}
[self.tableView reloadData];
}
you use the deferent state to set image like this.

I have created two radio buttons on one tableview cell.That are options for a question,But when I select them they both are get selected that I don't want,I want to select only one of them but I am not able to do that......Please help me Here is my code for customCell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *cellIdentifier = #"cell";
customCell *cell = (customCell *)[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if (cell == nil)

cell = [nib objectAtIndex:0];
}

[leftBtnclick setTag:0];
[leftBtnclick setImage:[UIImage imageNamed:#"unchecked.png"] forState:UIControlStateNormal];
[leftBtnclick setImage:[UIImage imageNamed:#"checked.png"] forState:UIControlStateSelected];
[leftBtnclick setFrame:CGRectMake(50, 120, 30, 30)];
[leftBtnclick addTarget:self action:#selector(leftTickBtnClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:leftBtnclick];

}
Firstly , set leftBtnclick.tag=999 and rightBtnclick.tag=1000.
And then add this code:-
-(void)leftTickBtnClicked:(id)sender
{
UIButton *leftTickBtn=(UIButton *)sender;
leftTickBtn.selected=!leftTickBtn.selected;
for(UIView *vw in [[sender superview]subviews])
{
if([vw isKindOfClass:[UIButton class]] && vw.tag==1000)
{
UIButton *rightTickBtn=(UIButton *)vw;
if(leftTickBtn.selected)
{
rightTickBtn.selected=NO;
}
else
{
rightTickBtn.selected=YES;
}
}
}
}
-(void)rightTickBtnClicked:(id)sender
{
UIButton *rightTickBtn=(UIButton *)sender;
rightTickBtn.selected=!rightTickBtn.selected;
for(UIView *vw in [[sender superview]subviews])
{
if([vw isKindOfClass:[UIButton class]] && vw.tag==999)
{
UIButton *leftTickBtn=(UIButton *)vw;
if(rightTickBtn.selected)
{
leftTickBtn.selected=NO;
}
else
{
leftTickBtn.selected=YES;
}
}
}
}

I am having three button image in table view, I want to check the conditions between them. when I click the button 1 means background image change to blue colour. at the same time I click the button 1 it will move to normal state white colour. Same for another two buttons.

My condition is: when button 1 is clicked means button 3 should not change. when button 3 is clicked means button 1 should not change.button 2 can select in both the condition.
- (void)radiobtn:(UIButton *)button
{
if(button.tag == 1)
{
[button setImage:[UIImage imageNamed:#"lblue.png"] forState:UIControlStateSelected];
}
if(button.tag == 2)

}
if(button.tag == 3)

}
}
can any one help me in coding.
First of all you can set different tag for each button's like
button.tag == 1,
button.tag == 2,
button.tag == 3
And then after you can write your radiobtn Action like this way..
-(IBAction) radiobtn:(id)sender
{
UIButton *yourBtn = (UIButton *)[self.view viewWithTag:[sender tag]];
if(yourBtn.tag == 1) {
[yourBtn setImage:[UIImage imageNamed:#"lblue.png"] forState:UIControlStateSelected];
}
else if(yourBtn.tag == 2){
[yourBtn setImage:[UIImage imageNamed:#"eblue.png"] forState:UIControlStateSelected];
}
else{
[yourBtn setImage:[UIImage imageNamed:#"vblue.png"] forState:UIControlStateSelected];

Can you have a try on this..
Please check!! i have done same thing on my code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"UITableViewCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
}
UIView * selectedBackgroundView = [[UIView alloc] initWithFrame:cell.frame];
[selectedBackgroundView setBackgroundColor:[UIColor redColor]]; // set color here
[cell setSelectedBackgroundView:selectedBackgroundView];
self.tableview.separatorColor = [UIColor whiteColor];

NSLog(#"value %# -- iSeletedButton %d", [arrAnswrs objectAtIndex:indexPath.row], iSeletedButton);
switch (iSeletedButton) {
case 1:
_userResult.relationStatus = status;
_labelFrstStatus.text = status;
_labelFrstStatus.textColor = [UIColor blackColor];
break;
case 2:

break;
}
if (_userResult.relationStatus || _userResult.childrenStatus) {

[tableView reloadData];
}
U can set tags to button
button1.tag=1;
button2.tag=2;
button3.tag=3; //instead of tag 1 for all buttons
Take reference for buttons as button1,button2,button3 globally..
NSLog(#"%#",[[sender superview] class]); //UITableViewCellContentView
NSLog(#"%#",[[[sender superview] superview] class]); //UITableViewCellScrollView
NSLog(#"%#",[[[[sender superview]superview]superview] class]); //UITableViewCell
- (void)radiobtn:(UIButton *)button
{
if(button.tag==1)
{
//handle
CustomizedCellView * cell = (CustomizedCellView*)[[[button superview]superview]superview];
if ([button.imageView.image isEqual:[UIImage imageNamed:#"lblue.png"]]) {
[button setImage:[UIImage imageNamed:#"lwhite.png"] forState:UIControlStateSelected];
}
for (UIButton *btn in cell.contentView.subviews) {
if (btn.tag==3) {
[btn setImage:[UIImage imageNamed:#"vwhite.png"] forState:UIControlStateSelected];
}
}
}
else if(button.tag==2)
{
//handle
if ([button.imageView.image isEqual:[UIImage imageNamed:#"eblue.png"]]) {
[button setImage:[UIImage imageNamed:#"ewhite.png"] forState:UIControlStateSelected];
}
}
else if(button.tag==3)
{
//handle
CustomizedCellView * cell = (CustomizedCellView*)[[[sender superview]superview]superview];
if ([button.imageView.image isEqual:[UIImage imageNamed:#"vblue.png"]]) {
[button setImage:[UIImage imageNamed:#"vwhite.png"] forState:UIControlStateSelected];
}
for (UIButton *btn in cell.contentView.subviews) {
if (btn.tag==2) {
[btn setImage:[UIImage imageNamed:#"lwhite.png"] forState:UIControlStateSelected];
}
}
}
}
Hope it helps you...!
I have 1 UITableView has multiple UIButton (named is "Open"button with different tags) in each row, i set tag for them. Now, after click on any button in each row, it'll show a UIView (detailView). On detailView has 1 "Submit"button. I want to when user click on "Submit" button, "Open"button with tag selected is disable. How can i do that? I used this code :
Code to create tableview with mutiple "Open"button:
- (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];
UIButton *market = [UIButton buttonWithType:UIButtonTypeCustom];
[market addTarget:self action:#selector(marketPressedAction:) forControlEvents:UIControlEventTouchDown];
[market setTag:3000];
[market setFrame:CGRectMake(200, 6, 30, 30)];
[cell.contentView addSubview:market];
}
marketButton = (UIButton *)[cell.contentView viewWithTag:3000];
[marketButton setTag:indexPath.row];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
_tableView.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);
return cell;
}
And code when click on"Open"button:
- (void)marketPressedAction:(id)sender
{
UIButton *button = (UIButton *)sender;
buttontag = button.tag;
NSLog(#"Market button click at row %d",buttontag);
if ([sender isSelected]) {
[sender setImage:[UIImage imageNamed:#"Marketplace.png"] forState:UIControlStateHighlighted];
[sender setSelected:NO];
}
else {
[sender setImage:[UIImage imageNamed:#"MarketplaceSelect.png"] forState:UIControlStateSelected];
[sender setSelected:YES];
}
}
}
If you want your "Open" button to be disabled after you click submit button, you should use delegates
UIButton *btn = (UIButton *)sender;
btn.enabled = NO;
Try this one in button click method
EDITED :
Change you marketPressedAction parameter id to UIButton * and write code of below
-(void)marketPressedAction:(UIButton *)sender
{
[sender setImage:[UIImage imageNamed:#"Marketplace.png"] forState:UIControlStateHighlighted];
[sender setImage:[UIImage imageNamed:#"MarketplaceSelect.png"] forState:UIControlStateSelected];
/// Here set you image ////////////////
[sender setImage:[UIImage imageNamed:#"myCustome.png"] forState:UIControlStateNormal];
[self createMarketPlaceForm]; // call detailView
sender.enabled = NO;
sender.userInteractionEnabled = NO;
}
When the user clicks on a UIButton on tableview ( tableview has mutiple button in each row), another View is shown.
I want to change image for this button after the user has clicked on the Done button of the other UIView. How can I do that? I'm a newbie. Could you please provide some code for me? Thanks in advance.
UPDATE CODE:
Code for tableview :
- (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];
UIButton *market = [UIButton buttonWithType:UIButtonTypeCustom];
[market addTarget:self action:#selector(marketPressedAction:) forControlEvents:UIControlEventTouchDown];
[market setTag:3000];
[market setFrame:CGRectMake(200, 6, 30, 30)];
[cell.contentView addSubview:market];
}
for (UIButton *button in [cell subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
button.tag = indexPath.row;
[button setImage:[UIImage imageNamed:#"Marketplace.png"] forState:UIControlStateNormal];
}
}
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
_tableView.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);
return cell;
}
Code for Open button ( button that user click on to show another View)
- (void)marketPressedAction:(id)sender
{
UIButton *button = (UIButton *)sender;
buttontag = button.tag;
NSLog(#"Market button click at row %d",buttontag);
}
And code for Done button:
-(void)submitMarket
{
for (UIButton *button in [_tableView subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
if (button.tag == buttontag) {
[button setBackgroundImage:[UIImage imageNamed:#"MarketplaceSelect.png"] forState:UIControlStateNormal];
}
}
}
}
Try this :
[yourButton setBackgroundImage:someImge forState:UIControlStateNormal];
Code on button click :
savedTag = button.tag;
Code on Done button click :
for (UIButton *button in [table subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
if (button.tag == savedtag) {
[button setBackgroundImage:someImge forState:UIControlStateNormal];
}
}
}
In cellForRowAtIndexPath in place of this : [market setTag:3000]; write [market setTag:indexPath.row];
Try this :
Replace :
marketButton = (UIButton *)[cell.contentView viewWithTag:3000];
[marketButton setTag:indexPath.row];
With this :
for (UIButton *button in [cell subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
button.tag == indexPath.row;
}
}
One more thing : make first line of cellForRowAtIndexPath as :
NSString *CellIdentifier = #"tableCell";
Change your cellForRowAtIndexPath as :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
NSString *CellIdentifier = #"cell";
UITableViewCell *cell = [_tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
UIButton *market = [UIButton buttonWithType:UIButtonTypeCustom];
[market addTarget:self action:#selector(marketPressedAction:) forControlEvents:UIControlEventTouchDown];
[market setImage:[UIImage imageNamed:#"Marketplace.png"] forState:UIControlStateNormal];
[market setTag:indexPath.row];
[market setFrame:CGRectMake(200, 6, 30, 30)];
[cell.contentView addSubview:market];
}
else {
for (UIButton *button in [cell subviews]) { // change name of table here
if ([button isKindOfClass:[UIButton class]]) {
button.tag = indexPath.row;
}
}
}
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
_tableView.contentInset = UIEdgeInsetsMake(0, 0, 100, 0);
return cell;
}
you can use a delegate or a NSNotificationCenter,
in your view where is Done button, you need create a property
#property (weak, nonatomic) <protocol_name> delegate;
and in your action method for DoneButton, you need to send a message to that delegate
[self.delegate method_name];
and the other view will be set as delegate for this one
`[viewWithDoneButton setDelegate:self];
and you need to implement the delegate method `
You can set another image for selected state of your button and after click on Done button just set selected state your button.
[yourButton setBackgroundImage:someImge forState:UIControlStateSelected];
after Done button:
[yourButton setSelected:YES];
Or if you use before UIControlStateSelected you can also use any other state. Or even users state - UIControlStateApplication
