I'm using table view in view controller.tableviewcell shows the same data only in the row.I'm having action button in the view controller. If I pressed a button the output shown in the tableviewcell it is concept. I don't know how to allocate string as a array. I'm using device as nsarray
- (void)viewDidLoad{
[super viewDidLoad];
self.label.text = #"";
device=[[NSString alloc]init];
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 2;
}
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
//cell = [tableView dequeueReusableCellWithIdentifier:cellID];
//if (!cell)
//cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:cellID] autorelease];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell==nil)
{
cell =[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text=[NSString stringWithFormat:#"%#",device];
cell.accessoryType=UITableViewCellAccessoryDetailDisclosureButton;
return cell;
}
-(void)peripheralManagerDidConnectPeripheral:(PeripheralManager *)manager
{
device = [NSString stringWithFormat:#" %#", manager.deviceName];
[self.deviceTable reloadData];

I am trying to implement multiselection in table view. But it is not working. When I add the below code it just shows me the single section for the elements in the table view. When I remove this line from code then I am able to select but not able to deselect the items.
Removed line code:multi selection works but not able to deselect
for (i=0; i<[arr_selectedCells count]; i++) {
NSInteger currentValue = [(NSNumber *)[arr_selectedCells objectAtIndex:i] integerValue];
if (currentValue==indexPath.row) {
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
}
correct.
Code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
cell.textLabel.text=user_friend.name;
NSLog(#"name is %#",user_friend.name);
int i;
for (i=0; i<[arr_selectedCells count]; i++)
{
NSInteger currentValue = [(NSNumber *)[arr_selectedCells objectAtIndex:i]integerValue];
if(currentValue==indexPath.row)
{
cell.accessoryType=UITableViewCellAccessoryCheckmark;
}
else
{
cell.accessoryType=UITableViewCellAccessoryNone;
}
}
return cell;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
if(![arr_userFriends containsObject:[NSNumber numberWithInteger:indexPath.row]])
{
[arr_selectedCells addObject:[NSNumber numberWithInteger:indexPath.row]];
}
else
{
[arr_selectedCells removeObject:[NSNumber numberWithInteger:indexPath.row]];
}
NSLog(#"numr is %ld",(long)indexPath.row);
[tableView reloadData];
}
Please tell me where I am going wrong?
i just edited your code! and i hope it works for you
tableView CellForRowAtIndexPath
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
cell.textLabel.text=user_friend.name;
if([arr_selectedCells containsObject:user_friend.name])
cell.accessoryType = UITableViewCellAccessoryCheckmark;
else
cell.accessoryType = UITableViewCellAccessoryNone;
return cell;
}
didSelectRowAtIndexPath
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UserFriend *user_friend=[arr_userFriends objectAtIndex:indexPath.row];
if([arr_selectedCells containsObject:user_friend.name])
{
[arr_selectedCells removeObject:user_friend.name];
}
else
{
[arr_selectedCells addObject:user_friend.name];
}
[tableView reloadRowsAtIndexPaths:#[indexPath] withRowAnimation:UITableViewRowAnimationNone];
}
try these
tableView.allowsSelection=YES;
tableView.allowsSelectionDuringEditing = YES;
Please tell me how I can be derived for each cell section?
Currently displays 4 sections, but only the first cell (identical).
Here's the code:
#implementation ViewController{
NSArray *tableCellTitle;
NSArray *sectionsTitle;
}
- (void)viewDidLoad {
[super viewDidLoad];
// Do any additional setup after loading the view, typically from a nib.
tableCellTitle = [NSArray new];
tableCellTitle = #[#"Cell 1", #"Cell 2", #"Cell 3", #"Cell 4"];
sectionsTitle = [NSArray new];
sectionsTitle = #[#"Section 1", #"Section 2", #"Section 3", #"Section 4"];
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"TableCell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableCellTitle objectAtIndex:indexPath.row];
return cell;
}
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
// Return the number of sections.
return [tableCellTitle count];
}
-(NSString)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section
{
return [sectionsTitle objectAtIndex:section];
}
You have to return like this for numberOfSectionsInTableView method instead of 1.
-(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return sectionsTitle.count;
}
And in cellRowAtIndexPath: method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *simpleTableIdentifier = #"TableCell";
UITableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:simpleTableIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:simpleTableIdentifier];
}
cell.textLabel.text = [tableCellTitle objectAtIndex:indexPath.section];
return cell;
}
i am facing one module consists to load two different UITableView in same UIViewController i know where i doing mistake, the problem is cell for row AtIndexpath in table view method. i getting only one UITableView in UIViewController but my secondviewcontroller not return any values in cell.
here my sample code for ur reference:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
if (tableView==table) {
return [self.arryData count];
}
else
return [tblArr count];
NSLog(#"tabeCount==>%lu",(unsigned long)tblArr.count);
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 55;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
static NSString *CellIdentifier1 = #"Cell";
dequeueReusableCellWithIdentifier:CellIdentifier];
UITableViewCell *cell;
mobilePlanDetailsCellTableViewCell *plan_cell;
if (tableView==table) {
cell = [self.table dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
cell.textLabel.font = [UIFont systemFontOfSize:12];
cell.textLabel.text = [self.arryData objectAtIndex:indexPath.row];
}return cell;
if (tableView==planTable) {
plan_cell = [self.planTable dequeueReusableCellWithIdentifier:CellIdentifier1];
if (plan_cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"mobilePlanDetailsCellTableViewCell" owner:self options:nil];
plan_cell = [nib objectAtIndex:0];
}
plan_cell.label.text = [[tblArr objectAtIndex:indexPath.row] objectForKey:#"Answer1"];
plan_cell.Label2.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer2"];
plan_cell.Label3.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer3"];
plan_cell.label4.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer4"];
}
return plan_cell;
}
- (void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath {
[tableView setBackgroundColor:[UIColor whiteColor]];
[cell setBackgroundColor:[UIColor whiteColor]];
}
you made the small mistake just change the Return Cell in inside the method
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
if (tableView==table) {
UITableViewCell *cell = [self.table dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
cell.textLabel.font = [UIFont systemFontOfSize:12];
cell.textLabel.text = [self.arryData objectAtIndex:indexPath.row];
return cell;
}
else {
mobilePlanDetailsCellTableViewCell *plan_cell = [self.planTable dequeueReusableCellWithIdentifier: CellIdentifier];
if (plan_cell == nil) {
NSArray *nib = [[NSBundle mainBundle] loadNibNamed:#"mobilePlanDetailsCellTableViewCell" owner:self options:nil];
plan_cell = [nib objectAtIndex:0];
}
plan_cell.label.text = [[tblArr objectAtIndex:indexPath.row] objectForKey:#"Answer1"];
plan_cell.Label2.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer2"];
plan_cell.Label3.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer3"];
plan_cell.label4.text = [[tblArr objectAtIndex:indexPath.row]objectForKey:#"answer4"];
return plan_cell;
}
}
The problem is that you are returning the cell outside the if (tableView==table), so your program will NOT reach the code after it.
Instead of
if (tableView==table) {
cell = [self.table dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
cell.textLabel.font = [UIFont systemFontOfSize:12];
cell.textLabel.text = [self.arryData objectAtIndex:indexPath.row];
}return cell; //This line is wrong
You should do this:
if (tableView==table) {
cell = [self.table dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc]
initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];
}
cell.textLabel.font = [UIFont systemFontOfSize:12];
cell.textLabel.text = [self.arryData objectAtIndex:indexPath.row];
//Should be inside the if scope
return cell;
}
Why you are doing such complex coding, Just simply provide different tag value for Table Views, and you are returning cell outside of your if condition which is wrong. Follow the below code.
Do a checking like this:-
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(tableView.tag==1)// Table 1
{
//load cell as per your choice
//cell operations
return cell;
}
else // Table 2
{
//load cell as per your choice
//cell operations
return cell;
}
I assign some custom view to UITableViewCell.accessoryView， but if I scroll the tableView crazy, some accessoryView will disappear in iOS 7, and if I touch the cell, it's accessoryView can appear, I don't know why, because it's correct in iOS 6. This is my code, someone can help me?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
cell.textLabel.text = [NSString stringWithFormat:#"CELL %d", (int)indexPath.row+1];
NSDictionary * dict = [_dataSource objectAtIndex:indexPath.row];
if ([dict objectForKey:#"switch"])
{
cell.accessoryView = [dict objectForKey:#"switch"];
}
else
{
cell.accessoryView = nil;
}
return cell;
}
When we use ReusableCellWithIdentifier in table view it reuse cells in table, you set cell.accessoryView = nil; it's remove accessory view for all cells in table view with same CellIdentifier try this code, it's solve your problem :
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"Cell";
NSDictionary * dict = [_dataSource objectAtIndex:indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
cell.accessoryView = [dict objectForKey:#"switch"];
}
cell.textLabel.text = [NSString stringWithFormat:#"CELL %d", (int)indexPath.row+1];
if ([dict objectForKey:#"switch"])
{
cell.accessoryView.hidden=NO;
}
else
{
cell.accessoryView.hidden=YES;
}
return cell;
}
I would like to populate a tableview with a NSMutableData that received from a webservice. I can get the data and display at several components but cannot fill the tableview because following code doesn't accept NSMutableData ;
AnyNSarray = [NSPropertyListSerialization propertyListWithData: webData options: 0 format:&plf error: &error];
//webData is NSMutableData that i populate with webservice data and AnyNSarray is a NSArray to provide tableview at
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
Here is tableview populating blocks (also following code works at view loads but is not fired again after i click button):
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"cell%i",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.textLabel.text = [birnsarray objectAtIndex:indexPath.row];
cell.detailTextLabel.text = #"any details";
}
return cell;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return AnyNSarray.count;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [birnsarray count];
}
Hey in numberOfRows function you are returning AnyNSarray count, so replace your cellForRowAtIndexPath with the below code.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
NSString *CellIdentifier = [NSString stringWithFormat:#"cell%i",indexPath.row];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
cell.textLabel.text = [AnyNSarray objectAtIndex:indexPath.row];
cell.detailTextLabel.text = #"any details";
}
return cell;
}
