Actions on the buttons of the cell - ios

In UITableViewCell there are different buttons on different cells and when I click on the button of the cell the same action is being performed on all the cell's button, but I want that when I press the button of particular cell then the action of that cell should work, I know I need to put them in array, but how?
when I click on the button one value is being incremented and it should be shown on the label of the same cell.
here is the code:-
- (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];
}
SHEDLIST *info1 = [shed_list objectAtIndex:indexPath.row];
cell.textLabel.text=info1.SHED_Name;
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
IDlbl = [[UILabel alloc] initWithFrame:CGRectMake(100, 0, 50, 50)];
IDlbl.text = info1.SHED_ID;
IDlbl.textAlignment = NSTextAlignmentCenter;
[cell addSubview:IDlbl];
tickbtn = [UIButton buttonWithType:UIButtonTypeCustom];
[tickbtn setBackgroundImage:[UIImage imageNamed:#"tick.png"]forState:UIControlStateNormal];
[tickbtn addTarget:self action:#selector(addsheddata) forControlEvents:UIControlEventTouchUpInside];
tickbtn.frame = CGRectMake(170, 5, 30, 30);
[cell addSubview:tickbtn];
return cell;
}
-(void) addsheddata:(UIEvent *)event
{
// here i am performing my action which i want.
}

First assign tag to your button.
[tickbtn setTag:indexPath.row];
[tickbtn addTarget:self action:#selector(addsheddata:) forControlEvents:UIControlEventTouchUpInside];
tickbtn.frame = CGRectMake(170, 5, 30, 30);
[cell addSubview:tickbtn];
Correct your method implementation by this.
-(IBAction) addsheddata:(UIControl *)sender
{
// here i am performing my action which i want.
UIButton *button = (UIButton*)sender;
NSIndexPath *myIP = [NSIndexPath indexPathForRow:sender.tag inSection:0];
//Type cast cell
UITableViewCell *cell = (UITableViewCell*)[mytblView cellForRowAtIndexPath:myIP];
UILabel *lbl = cell.lbl;
lbl.text = #"Your text";
}

Add target like this to your button
[tickbtn addTarget:self action:#selector(addsheddata:event:) forControlEvents:UIControlEventTouchUpInside];
And method should be like this:
- (void) addsheddata:(id)sender event:(id)event {
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:chatContent];
NSIndexPath *indexPath = [YOUR_TABLE_OBJ indexPathForRowAtPoint: currentTouchPosition];
UITableViewCell *cell = [YOUR_TABLE_OBJ cellForRowAtIndexPath:indexPath];
}

tickbtn = [UIButton buttonWithType:UIButtonTypeCustom];
[tickbtn setBackgroundImage:[UIImage imageNamed:#"tick.png"]forState:UIControlStateNormal];
[tickbtn addTarget:self action:#selector(addsheddata) forControlEvents:UIControlEventTouchUpInside];
tickbtn.frame = CGRectMake(170, 5, 30, 30);
[cell addSubview:tickbtn];
NSString *str=[urarray objectAtIndex:indexPath.row];
[tickbtn setTag:[str intValue]];
-(void) addsheddata:(UIEvent *)event
{
UITableViewCell *clickedCell = (UITableViewCell *)[sender superview] ;
NSIndexPath *clickedButtonPath = [urtableview indexPathForCell:clickedCell];
}

At cellForRowAtIndexPath
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
tickbtn.tag =500+indexPath.row;
//Initialise your UILabel *lbl and define
lbl.tag = 200+indexPath.row;
lbl.text = // Add Text
// Add the Uilabel to the tableView
}
Action by handling the tag
-(IBAction) addsheddata:(UIButton *)sender{
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag-500 inSection:0];
UILabel *lbl = (UILabel *)[self.view viewWithTag:indexPath.Row+200];
NSLog (#"%#", lbl.text);
// Do further as per your Requirement
}

iOS How to get button text from tableview cell

I am using simple tableview and i have add button in every cell , The Problem is how to get button text from cell number second and any other cell number get button text i am using this code but its not working
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
UITableViewCell *cell = [tbl_view cellForRowAtIndexPath:indexPath];
for( UITableViewCell *getview in cell.subviews)
{
if([getview isKindOfClass:[UIButton class]])
{
NSLog(#"sdfsdfsd");
// UIButton *button = (UIButton *);
}
}
This code is set button in tableview cell
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
UILabel *fromLabel = [[UILabel alloc]initWithFrame:CGRectMake(60, 5, 250,20)];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
cell=[[UITableViewCell alloc] init];
}
cell.backgroundColor=[UIColor clearColor];
UIButton *button_chaeckbox = [UIButton buttonWithType:UIButtonTypeCustom];
button_chaeckbox.backgroundColor=[UIColor clearColor];
button_chaeckbox.frame = CGRectMake(10, 10, 15, 15);
if( [checkedArray containsObject:[NSString stringWithFormat:#"%ld",(long)indexPath.row]])
{
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"checked_checkbox.png"] forState:UIControlStateNormal];
}else
{
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"empty_box_b.png"] forState:UIControlStateNormal];
}
[button_chaeckbox setTitle:#"creaButtonname" forState:UIControlStateNormal];
button_chaeckbox.tag=indexPath.row;
[button_chaeckbox addTarget:self
action:#selector(checkboxAction:)
forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:button_chaeckbox];
}
Please give me solution , i have try this code in ios 7 and ios 8 this is not working
Regards,
Nishant Chandwani
Do one thing give tag value for each button like
button_chaeckbox.tag=indexpath.row
in cellForRowAtIndexPath Method .
in checkboxAction do like this
NSString * titleText=sender.titleLabel.text
and you will check in button action method from which cell it is
like using conditions if(sender.tag == //your cell number second value//)
I think you want like this only .
Use this code for reuse cells in table view
- (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=[[UITableViewCell alloc] init];
UILabel *fromLabel = [[UILabel alloc]initWithFrame:CGRectMake(60, 5, 250,20)];
cell.backgroundColor=[UIColor clearColor];
UIButton *button_chaeckbox = [UIButton buttonWithType:UIButtonTypeCustom];
button_chaeckbox.backgroundColor=[UIColor clearColor];
button_chaeckbox.frame = CGRectMake(10, 10, 15, 15);
[button_chaeckbox addTarget:self
action:#selector(checkboxAction:)
forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:button_chaeckbox];
button_chaeckbox.tag=1001;
}
if( [checkedArray containsObject:[NSString stringWithFormat:#"%ld",(long)indexPath.row]])
{
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"checked_checkbox.png"] forState:UIControlStateNormal];
}else
{
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"empty_box_b.png"] forState:UIControlStateNormal];
}
}
Use this code for get button from cell
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
UITableViewCell *cell = [tbl_view cellForRowAtIndexPath:indexPath];
UIButton *button_chaeckbox=(UIButton*)[cell viewWithtag:1001]
You can try this
In cellForRowAtIndexPath
[cell.button setTitle:#"RAM" forState:UIControlStateNormal];
cell.button.tag=indexPath.row;
[cell.button addTarget:self action:#selector(cellBtn:) forControlEvents:UIControlEventTouchUpInside];
Selector method
-(void)cellBtn :(UIButton *)sender
{
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag inSection:0];
AlertCustomCell *cell = [tableview cellForRowAtIndexPath:indexPath];
NSString *user = cell.button.titleLabel.text;
NSLog(#"Text of button is :%#",user);
}
I hope it will work
let me point out one thing. if you want to traverse through all the subviews of the table cell you have to make for( UITableViewCell *getview in cell.subviews) to for( UIView *getview in cell.subviews)
The code would look like this
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
UITableViewCell *cell = [tbl_view cellForRowAtIndexPath:indexPath];
for( UIView *getview in cell.subviews)
{
if([getview isKindOfClass:[UIButton class]])
{
UIButton *button = (UIButton *)getView;
NSLog #("%#",button.titleLabel.text)
}
}
I would recommend making a UITableViewCell subclass and making the button a a property on that subclass. Then in your code would look something like this.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"SimpleTableItem";
CustomTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
UILabel *fromLabel = [[UILabel alloc]initWithFrame:CGRectMake(60, 5, 250,20)];
if (cell == nil) {
cell = [[CustomTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.backgroundColor=[UIColor clearColor];
UIButton *button_chaeckbox = [UIButton buttonWithType:UIButtonTypeCustom];
button_chaeckbox.backgroundColor=[UIColor clearColor];
button_chaeckbox.frame = CGRectMake(10, 10, 15, 15);
if( [checkedArray containsObject:[NSString stringWithFormat:#"%ld",(long)indexPath.row]])
{
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"checked_checkbox.png"] forState:UIControlStateNormal];
} else {
[button_chaeckbox setBackgroundImage:[UIImage imageNamed:#"empty_box_b.png"] forState:UIControlStateNormal];
}
[button_chaeckbox addTarget:self
action:#selector(checkboxAction:)
forControlEvents:UIControlEventTouchUpInside];
[cell setCellButton:button_chaeckbox];
return cell;
}
And then to get the button:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:1 inSection:0];
CustomTableCell *cell = (CustomTableCell *)[tbl_view cellForRowAtIndexPath:indexPath];
UIButton * yourButton = cell.CellButton

UiButton text wont stay changed in Tableview cell

I have searched all over the web and cant seem to find a solution to this simple problem. I have a table view of buttons when the work "like". When the Button is pressed, it changes the word to "Unlike". I got it to work but when I scroll down the table, I see other buttosn also change to "unlike" and sometimes overlaps it with "Like". And when I scroll back up, the original button I selected changes back to normal state. I understand the cells are reusable and thats why I am using a mutable array for my data source and still it doesnt work. Please help!
- (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];
}
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[myButton setTitle:#"Like" forState:UIControlStateNormal];
myButton addTarget:self action:#selector(tapped:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(14.0, 10.0, 125.0, 25.0);
myButton.tag =indexPath.row;
[cell.contentView addSubview:myButton];
cell.textLabel.text = [recipes objectAtIndex:indexPath.row];
return cell;
}
the action method:
-(void)tapped:(id)sender {
UIButton *senderButton = (UIButton *)sender;
UITableViewCell *parentCell = [[sender superview]superview];
NSIndexPath *indexPathLiked = [table indexPathForCell:parentCell];
[array replaceObjectAtIndex:senderButton.tag withObject:[NSNumber numberWithInt:1]];
[sender setTitle:#"Unlike" forState:UIControlStateNormal];
}
If the table calls the cellForRowAtIndexPath you create all the time a new button. When you get a reused cell the button still exists and you put a new one over there.
Change your method to:
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
UIButton *myButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[myButton setTitle:#"Like" forState:UIControlStateNormal];
myButton addTarget:self action:#selector(tapped:) forControlEvents:UIControlEventTouchUpInside];
myButton.frame = CGRectMake(14.0, 10.0, 125.0, 25.0);
myButton.tag =indexPath.row;
[cell.contentView addSubview:myButton];
}
else {
// todo: change the button title to "like" or "unliked" value
}
cell.textLabel.text = [recipes objectAtIndex:indexPath.row];
P.S. This make no sense, you doesn't use that, why you do that?
UITableViewCell *parentCell = [[sender superview]superview];
NSIndexPath *indexPathLiked = [table indexPathForCell:parentCell];
If you have only one section you can get the cell without using superview:
NSIndexPath *indexPath = [NSIndexPath indexPathForRow:sender.tag inSection:0]
UITableViewCell *parentCell = [table cellForRowAtIndexPath:indexPath];

selected accessoryView for specified cells

the question is quite simple. How can you make an accessoryView in a tableView to be "Selected" for each row that has the same title in both section 0 and 1? (iOS)
I want to do this because when I select the accessoryView in a row, the row copies up to a new section 0 which is called "favorites". But the problem is, if I deselect the row in section 0, the row disappears but the accessoryView stays selected for the corresponding row in section 1, which I wan't to be deselected in that case. Thanks in advance.
-(void)addToFavs:(id)sender event:(id)event {
NSSet *touches = [event allTouches];
UITouch *touch = [touches anyObject];
CGPoint currentTouchPosition = [touch locationInView:self.tableView];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint: currentTouchPosition];
UIButton *button = (UIButton*)sender;
if(indexPath!=nil){
if(button.selected==YES){
button.selected = NO;
}else{
button.selected =YES;
}
[self tableView: self.tableView accessoryButtonTappedForRowWithIndexPath: indexPath];
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//cell
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell){
// left image
UIImageView *image=[[UIImageView alloc] initWithFrame:CGRectMake(7, 7, 30, 30)];
cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.accessoryType = UITableViewCellAccessoryDisclosureIndicator;
cell.detailTextLabel.textColor=[UIColor lightGrayColor];
cell.textLabel.text=self.objects[indexPath.row];
cell.detailTextLabel.text =self.subtitles[indexPath.row];
[cell.contentView addSubview:image];
if(indexPath.section==0){
image.image=[UIImage imageNamed:[self.iconsFavs objectAtIndex:indexPath.row]];
cell.textLabel.text=self.favs[indexPath.row];
cell.detailTextLabel.text =self.subtitlesFavs[indexPath.row];
}else{
image.image=[UIImage imageNamed:[self.icons objectAtIndex:indexPath.row]];
}
//favorites image button
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect frame = CGRectMake(0.0, 0.0, 25, 25);
button.frame = frame;
button.showsTouchWhenHighlighted = YES;
[button setImage:[UIImage imageNamed:#"unfavorites.png"] forState:UIControlStateNormal];
[button setImage:[UIImage imageNamed:#"favorites.png"] forState:UIControlStateSelected];
[button addTarget:self action:#selector(addToFavs:event:) forControlEvents:UIControlEventTouchUpInside];
if(indexPath.section==0){
button.selected = !button.selected;
}
cell.accessoryView.tag=indexPath.row;
button.backgroundColor = [UIColor clearColor];
cell.accessoryView = button;
}
return cell;
}
Easy way to do this, create an array for favorite and add item to this array on select. And select accessory view if the item is in array of favorites.

Add permanent checkmark to tableView-cell

my viewController contains a tableView where the user can add cells via coreData.
I defined the cells:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Travel";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
NSManagedObject *travel = [self.travelling objectAtIndex:indexPath.row];
UILabel *countryLabel = (UILabel *)[cell viewWithTag:101];
kategorieLabel.text = [travel valueForKey:#"country"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
[button setBackgroundImage:[UIImage imageNamed:#"button.png"] forState:UIControlStateNormal];
[button addTarget:self action:#selector(buttonTapped:) forControlEvents:UIControlEventTouchUpInside];
button.frame = CGRectMake(15.0f, 32.0f, 24.0f, 20.0f);
[cell addSubview:button];
if ([[travel valueForKey:#"tick"] isEqualToString:#"yes"]) {
[cell setAccessoryType:UITableViewCellAccessoryCheckmark];
}else{
[cell setAccessoryType:UITableViewCellAccessoryNone];
}
return cell;
}
- (void)buttonTapped:(UIButton *)sender {
UITableViewCell *owningCell = (UITableViewCell*)[sender superview];
[owningCell setAccessoryType:UITableViewCellAccessoryCheckmark];
NSIndexPath *indexPath = [_tableView indexPathForCell:owningCell];
NSManagedObject *travel = [self.travelling objectAtIndex:indexPath.row];
[travel setValue:#"yes" forKey:#"tick"];
}
When the user taps a button on the cell, the checkmark should appear. But when I reload or restart the app not all checkmarks are there. Maybe there is a better method to do this.

Detect which button was clicked in a grouped UITableView

I have a grouped UITableView (this one has 4 sections) and several rows each. I have programatically created 2 buttons in each of the cells.
This is how I am creating the UITableViewCell. In this code, I am trying to detect the indexPath.row and the indexPath.section of the button that was pressed and pass it to the method. How am I able to do this ?
-(UITableViewCell*)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *cellId = #"Cell";
UITableViewCell *cell ;//= [tableView dequeueReusableCellWithIdentifier:nil];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:cellId];
}
NSString *docTitle = [currentDocument objectForKey:#"displayname"];
UIView *cellView = [[UIView alloc] initWithFrame:CGRectMake(cell.contentView.frame.origin.x+5, cell.contentView.frame.origin.y, cell.contentView.frame.size.width, cell.contentView.frame.size.height)];
UILabel *cellTitle = [[UILabel alloc] initWithFrame:CGRectMake(cellView.frame.origin.x + 5, cellView.frame.origin.y + 5, cellView.frame.size.width - 10, 25)];
cellTitle.backgroundColor = [UIColor clearColor];
cellTitle.text = docTitle;
[cellView addSubview:cellTitle];
[cell.contentView addSubview:cellView];
UIButton *viewDocumentButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[viewDocumentButton setTitle:#"View Online" forState:UIControlStateNormal];
viewDocumentButton.frame = CGRectMake(cellView.frame.origin.x + 5, cellTitle.frame.origin.y + cellTitle.frame.size.height + 5, 150, 35);
[viewDocumentButton addTarget:self action:#selector(openDocumentButtonPressedMethod:) forControlEvents:UIControlEventTouchDown];
[viewDocumentButton setTag:indexPath.row];
[cell.contentView addSubview:viewDocumentButton];
UIButton *downloadDocumentButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
[downloadDocumentButton setTitle:#"Download Document" forState:UIControlStateNormal];
downloadDocumentButton.frame = CGRectMake(cellView.frame.origin.x + 5, viewDocumentButton.frame.origin.y + viewDocumentButton.frame.size.height + 5, 150, 35);
[downloadDocumentButton addTarget:self action:#selector(openDocumentButtonPressedMethod:) forControlEvents:UIControlEventTouchDown];
[downloadDocumentButton setTag:indexPath.row];
[cell.contentView addSubview:downloadDocumentButton];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
Additionally, you could...
- (IBAction)openDocumentButtonPressedMethod:(id)sender {
UIButton *button = (UIButton *)sender;
UIView *contentView = button.superview;
UITableViewCell *cell = (UITableViewCell *)contentView.superview;
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
// do something with the indexPath
}
And if you wanted to use the same method to handle both button events, then you could use the tag on the button to distinguish between the two buttons.
if (button.tag == 1) {
// do something with the indexPath view related
}
else {
// do something with the indexPath download related
}
Create a subclass of UIButton
#interface MyButton : UIButton
{ /* indexPath, other stuff */ }
#end
Then implement
- (void)sendAction:(SEL)action to:(id)target forEvent:(UIEvent *)event
to do something with the indexPath and other stuff before invoking the super for this method.
When you create the button, provide indexPath.
In your openDocumentButtonPressedMethod: method, do
CGPoint pointInTableView = [self.tableView convertPoint:sender.bounds.origin fromView:sender];
NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:pointInTableView];
