Hey Guys, please let me know how can I set this code action in to an UIButton action...
Here is the code:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *myIdentiFier=#"myIdentiFier";
myCell *cell=[tableView dequeueReusableCellWithIdentifier:myIdentiFier];
if(!cell){
//cell=[[UITableViewCell alloc]initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:myIdentiFier];
NSArray *nib=[[NSBundle mainBundle]loadNibNamed:#"myCell" owner:self options:nil];
for(id obj in nib){
if([obj isKindOfClass:[myCell class]]){
cell=(myCell *)obj;
break;
}
}
}
NSDictionary *diction=(NSDictionary*)[content objectAtIndex:indexPath.row];
[cell.contentView setBackgroundColor:[UIColor orangeColor]];
cell.empID.text=[diction objectForKey:#"empid"];
cell.empName.text=[diction objectForKey:#"empname"];
cell.designation.text=[diction objectForKey:#"empdesignation"];
cell.teamName.text=[diction objectForKey:#"empteam"];
return cell;
}
i want to set above action in my button..
- (IBAction)displayRecord:(id)sender {
}
please tell me ...
you can call
[tableview reloadData]
than cellForRowAtIndexPath is called.
simply u can do as follow
- (IBAction)displayRecord:(id)sender {
[yourTablename reloadData];
}

Here I want a Multilevel tableview. I was able to create it successfully but when one of the levels is selected, any previously expanded dropdown level should collapse. I used the sample code below.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"cellid"];
if (cell==nil){
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"cellid"] autorelease];
}
[cell setSelectionStyle:UITableViewCellSelectionStyleNone];
[cell.textLabel setText:[[arrtable objectAtIndex:indexPath.row] objectForKey:#"name"]];
[cell setIndentationLevel:[[[arrtable objectAtIndex:indexPath.row] objectForKey:#"level"] intValue]];
return cell;
}
When did select the row
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(#"arrtable :%#",arrtable);
NSDictionary *d=[arrtable objectAtIndex:indexPath.row];
NSLog(#"d%#",d);
if([d valueForKey:#"objects"]) {
NSArray *ar=[d valueForKey:#"objects"];
BOOL isAlreadyInserted=NO;
for(NSDictionary *dInner in ar ){
NSInteger index=[arrtable indexOfObjectIdenticalTo:dInner];
isAlreadyInserted=(index>0 && index!=NSIntegerMax);
if(isAlreadyInserted) break;
}
if(isAlreadyInserted) {
[self miniMizeThisRows:ar];
} else {
NSUInteger count=indexPath.row+1;
NSMutableArray *arCells=[NSMutableArray array];
for(NSDictionary *dInner in ar ) {
[arCells addObject:[NSIndexPath indexPathForRow:count inSection:0]];
[arrtable insertObject:dInner atIndex:count++];
}
[tableView insertRowsAtIndexPaths:arCells withRowAnimation:UITableViewRowAnimationLeft];
}
}
}
- (void)miniMizeThisRows:(NSArray*)ar{
for(NSDictionary *dInner in ar ) {
NSUInteger indexToRemove=[arrtable indexOfObjectIdenticalTo:dInner];
NSArray *arInner=[dInner valueForKey:#"objects"];
if(arInner && [arInner count]>0){
[self miniMizeThisRows:arInner];
}
if([arrtable indexOfObjectIdenticalTo:dInner]!=NSNotFound) {
[arrtable removeObjectIdenticalTo:dInner];
[testtable deleteRowsAtIndexPaths:[NSArray arrayWithObject:
[NSIndexPath indexPathForRow:indexToRemove inSection:0]
]
withRowAnimation:UITableViewRowAnimationRight];
}
}
}

My Created own class for dropdown tableview i think it will be use full to you.
In my app I have custom UITableViewCell, and I have UIStepper and UILabel in the custom cell. I don't know how to check which stepper was clicked. So is it a way to know from which cell stepper was clicked?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
NSString *CellIdentifier = #"Cell";
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"CustomCell" owner:self options:nil];
if ([nib count] > 0) {
cell = self.tbcell;
}
}
return cell;
}
An alternative is:
In the method that gets fired when the UIStepper value changes (e.g. #max_, above), you can do the following:
- (IBAction)stepperValueDidChanged:(UIStepper *)sender {
UITableViewCell *cell = (UITableViewCell *)[[sender superview] superview];
// assuming your view controller is a subclass of UITableViewController, for example.
NSIndexPath *indexPath = [self.tableView indexPathForCell:cell];
}
[step addTarget:self action:#selector(someAction:) forControlEvents:UIControlEventValueChanged];
- (void) someAction:(UIStepper *) stepper {
NSLog(#"stepper clicked");
}
I'm working with UITableView in UIViewController..I am using the following delegate methods.....
-(NSInteger) tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
-(UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
Once I load the view I find all delegates has been called..... But I need to call these methods in a button click.....
I tried in this way....
[self tableView:table numberOfRowsInSection:rows];
[self tableView:table cellForRowAtIndexPath:path];
I find that these methods has been called,but nothing happened (code inside these delegates doesn't works).... I don't knw why??? Any suggestions???
Write the code inside the button click function it will call all the delegates of the tableview
[self.tableView reloadData];
or complete code to your solution is:-
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
customCell *cell = [[customCell alloc]init];
if (cell == nil) {
cell = [[[customCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
}
// Configure the cell
cell.selectionStyle = UITableViewCellSelectionStyleBlue;
NSArray *topLevelObjects=[[NSBundle mainBundle] loadNibNamed:#"customCell" owner:self options:nil];
cell = (customCell *)[topLevelObjects objectAtIndex:0];
int count=0;
for(id currentObject in topLevelObjects)
{
count++;
if([currentObject isKindOfClass:[customCell class]])
{
cell= (customCell *)currentObject;
UILabel *sName = (UILabel *)[cell.contentView viewWithTag:1];
//Checking the flag that is set in the btnClicked event
if (flag) {
sName.hidden=YES;
}
else{
sName.text = [arrayResult objectAtIndex:indexPath.row];
}
}
}
return cell;
[topLevelObjects release];
[cell release];
}
-(IBAction) btnClicked:(id) sender{
flag=YES;
[self.tableView reloadData];
}
Try this it will work..
In my UITableView, i need to get the event of the user, so when the cell is selected(checked), i put btn_checked.png and when it's unchecked, i put the btn_unchecked.png.
I guess, what i try to do should be in the didSelectRowAtIndexPath method, so this is my code:
- (void)tableView:(UITableView *)tableView
didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSArray *listData =[self->tableContents objectForKey:
[self->sortedKeys objectAtIndex:[indexPath section]]];
UITableViewCell* theCell = [tableView cellForRowAtIndexPath:indexPath];
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"btn_unchecked.png"]];
theCell.accessoryView = imageView;
}
My snippet code doesn't work, so the btw_unchecked.png isn't placed when the row is checked, also, i need to get the event of checked/unchecked to place the right image to the right event.
Thanx in advance.
As an example, this code snippet will toggle the cell's checkmark when the cell is tapped. The pattern is to force a selective reload from the table's datasource when the delegate method is invoked.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// Dequeue the cell... then:
static NSString *CellIdentifier = #"tvcOEList";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.accessoryType = (cell.accessoryType == UITableViewCellAccessoryNone) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
[self.tableView reloadRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:YES];
}
You can use following code.
[cell.contentView addSubview:imageView];
i hope this will help you..
I have a bit of a problem where my check marks that i apply to my rows in my UITableView get all mixed up when i scroll. Im pretty sure this has to do with how the iphone reuses the cells and when i scroll away from on that has a check mark it probably puts it back in when i gets a chance.
Could someone please give me some tips on how I might avoid this or possibly take a look at my methods and see if anything looks off?
I was thinking that maybe I could save each row selection that the user made and then check to see which rows were being displayed to make sure the correct ones got the checkmark but I could'nt see a way to do so.
Thanks so much.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
[cell setAccessoryView:nil];
}
NSMutableArray *temp = [[NSMutableArray alloc]init];
for (int j = 0; j < [listOfRowersAtPractice count]; j++) {
if ([[differentTeams objectAtIndex:indexPath.section] isEqualToString:[[rowersAndInfo objectForKey:[listOfRowersAtPractice objectAtIndex:j]]objectForKey:#"Team"]]) {
[temp addObject:[listOfRowersAtPractice objectAtIndex:j]];
}
}
[cell.cellText setText:[temp objectAtIndex:indexPath.row]];
[temp removeAllObjects];
[temp release];
// Set up the cell...
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView deselectRowAtIndexPath:indexPath animated:YES];
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
if (cell.accessoryType != UITableViewCellAccessoryCheckmark) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else {
cell.accessoryType = UITableViewCellAccessoryNone;
}
}
Yes save the state of the row which is selected and in cellforrowatindexpath after you get the cell reset it to default state and check the state of the row and change the state.
EDIT:
You can create a NSMutabaleArray with number of items equal to the number of items in your datasource which is the name temp in your code.
On select you can actually change the value at that index to some text like #"selected" in the above created array.
In your cellforrowatindexpath you can check this text if its selected or unselected and then change the property of the cell. Its like maintaining a bitmap state for selected and unselected states.
Give this a go :
static NSString *CellIdentifier = [NSString stringWithFormat:#"Cell %d",indexPath.row];
I had the same problem on one of my app's.
As for the check marks, are you using a core data store at all?
If you are use the following....
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
NSManagedObject *item = [[self fetchedResultsController] objectAtIndexPath:indexPath];
if ([[item valueForKey:#"checks"] boolValue]) {
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[cell.textLabel setTextColor:[UIColor redColor]];
[cell.detailTextLabel setTextColor:[UIColor redColor]];
} else {
cell.accessoryType = UITableViewCellAccessoryNone;
[cell.textLabel setTextColor:[UIColor blackColor]];
[cell.detailTextLabel setTextColor:[UIColor blackColor]];
}
}
And......
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
NSManagedObject *selectedObject = [self.fetchedResultsController objectAtIndexPath:indexPath];
if ([[selectedObject valueForKey:#"checks"] boolValue]) {
[selectedObject setValue:[NSNumber numberWithBool:NO] forKey:#"checks"];
} else {
[selectedObject setValue:[NSNumber numberWithBool:YES] forKey:#"checks"];
}
[managedObjectContext save:nil];
}
You need to reset/clear all settings in the cell whenever you reuse the cell.
So here, right after you get the cell,
you need to do something like
CustomCell *cell = (CustomCell*)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];
[cell setAccessoryView:nil];
}
cell.accessoryType = UITableViewCellAccessoryNone // This and other such calls to clean up the cell
You need refresh the accessoryType of cell, because the cell is reused then it inherited the accessoryType from a reused Cell, this is the solution:
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"cellIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
//Refresh acessory for cell when tableview have many cells and reuse identifier
if([self.tableView.indexPathsForSelectedRows containsObject:indexPath]){
cell.accessoryType = UITableViewCellAccessoryCheckmark;
}else{
cell.accessoryType = UITableViewCellAccessoryNone;
}
cell.textLabel.text = #"Your text cell";
return cell;
}
it worked for me..
in cell for row at index path i had created a checkbox button..
after everytym tableview is scrolled cellForRowAtIndexPath Method gets called
hence i had to add condition in cellForRowAtIndexPath to check whether a cell has a checked or unchecked button
static NSString *simpleTableIdentifier = #"SimpleTableCell";
SimpleTableCell *cell = (SimpleTableCell *)[tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"SimpleTableCell" owner:self options:nil];
cell = [nib objectAtIndex:0];
}
cell.nameLabel.text = [tableData objectAtIndex:indexPath.row];
cell.thumbnailImageView.image = [UIImage imageNamed:[thumbnails objectAtIndex:indexPath.row]];
cell.prepTimeLabel.text = [prepTime objectAtIndex:indexPath.row];
checkbox = [[UIButton alloc]initWithFrame:CGRectMake(290, 5, 20, 20)];
[checkbox setBackgroundImage:[UIImage imageNamed:#"checkbox_empty.png"]
forState:UIControlStateNormal];
[checkbox addTarget:self action:#selector(checkUncheck:) forControlEvents:UIControlEventTouchUpInside];
[cell addSubview:checkbox];
if(selectedRows.count !=0)
{
if([[selectedRows objectAtIndex:indexPath.row]integerValue]==1)
{
[checkbox setImage:[UIImage imageNamed: #"checkbox_full.png"] forState:UIControlStateNormal];
}
else
{
[checkbox setImage:[UIImage imageNamed: #"checkbox_empty.png"] forState:UIControlStateNormal];
}
}
return cell;
}
method to define selection of checkbox is as
- (IBAction)checkUncheck:(id)sender {
UIButton *tappedButton = (UIButton*)sender;
NSLog(#"%d",tappedButton.tag);
if ([[sender superview] isKindOfClass:[UITableViewCell class]]) {
UITableViewCell *containerCell = (UITableViewCell *)[sender superview];
NSIndexPath *cellIndexPath = [self.tableView indexPathForCell:containerCell];
int cellIndex = cellIndexPath.row;
NSLog(#"cell index%d",cellIndex);
[selectedRows insertObject:[NSNumber numberWithInt:1] atIndex:cellIndex];
}
NSLog(#"%#",selectedRows);
if([tappedButton.currentImage isEqual:[UIImage imageNamed:#"checkbox_empty.png"]])
{
[sender setImage:[UIImage imageNamed: #"checkbox_full.png"] forState:UIControlStateNormal];
}
else
{
[sender setImage:[UIImage imageNamed: #"checkbox_empty.png"] forState:UIControlStateNormal];
}
}
do not forget to initialize selectedRows array..
happy coding...!!!
