I am using two UITableView in same View. I have used prototype cell in which there are two label to show date and venue in TableView.
Here is the code what I did. Both TableViews showing same data.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableView *tableViewOne=(UITableView*)[self.view viewWithTag:5];
UITableView *tableViewtwo=(UITableView*)[self.view viewWithTag:6];
UITableViewCell *cell;
if (tableViewOne) {
NSLog(#"In Table1");
static NSString *CellIdentifier = #"cell";
cell=[tableViewOne dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
UILabel * dateLabel = (UILabel*)[cell viewWithTag:111];
dateLabel.text = [dateArrayLableInTableviewOne objectAtIndex:indexPath.row];
UILabel *venueLabel=(UILabel*)[cell viewWithTag:114];
venueLabel.text=[venueArrayLabelInTableViewOne objectAtIndex:indexPath.row];
}
else if(tableViewtwo){
NSLog(#"In Tabl2 ");
static NSString *CellIdentifier2 = #"cellTwo";
cell = [tableViewtwo dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];
}
UILabel * dateLabelOfTableViewTwo = (UILabel*)[cell viewWithTag:211];
dateLabelOfTableViewTwo.text = [dateArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
UILabel *venueLabelOfTableViewTwo=(UILabel*)[cell viewWithTag:214];
venueLabelOfTableViewTwo.text=[venueArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
}
return cell;
}
Your if condition is incorrect. So please check like this
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
if (tableView.tag == 5) // Change here
{
NSLog(#"In Table1");
static NSString *CellIdentifier = #"cell";
cell=[tableViewOne dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
UILabel * dateLabel = (UILabel*)[cell viewWithTag:111];
dateLabel.text = [dateArrayLableInTableviewOne objectAtIndex:indexPath.row];
UILabel *venueLabel=(UILabel*)[cell viewWithTag:114];
venueLabel.text=[venueArrayLabelInTableViewOne objectAtIndex:indexPath.row];
}
else
{
NSLog(#"In Tabl2 ");
static NSString *CellIdentifier2 = #"cellTwo";
cell = [tableViewtwo dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];
}
UILabel * dateLabelOfTableViewTwo = (UILabel*)[cell viewWithTag:211];
dateLabelOfTableViewTwo.text = [dateArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
UILabel *venueLabelOfTableViewTwo=(UILabel*)[cell viewWithTag:214];
venueLabelOfTableViewTwo.text=[venueArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
}
return cell;
}
Do it like
if (tableView == tableViewOne){
// Your Code
}
elseif (tableView == tableViewTwo){
// Your Code
}
Your comaprison is incorrect since both table view are present, first condition get satisfied always thus same data in both tables.
Compare using UITableView object identifiers
if (tableView==first_table_view_name) {
}
else
{
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
//UITableView *tableViewOne=(UITableView*)[self.view viewWithTag:5];
//UITableView *tableViewtwo=(UITableView*)[self.view viewWithTag:6];
UITableViewCell *cell;
if (tableView.tag==5) // problem is here
{
NSLog(#"In Table1");
static NSString *CellIdentifier = #"cell";
cell=[tableViewOne dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
UILabel * dateLabel = (UILabel*)[cell viewWithTag:111];
dateLabel.text = [dateArrayLableInTableviewOne objectAtIndex:indexPath.row];
UILabel *venueLabel=(UILabel*)[cell viewWithTag:114];
venueLabel.text=[venueArrayLabelInTableViewOne objectAtIndex:indexPath.row];
}
else if(tableView.tag==6){
NSLog(#"In Tabl2 ");
static NSString *CellIdentifier2 = #"cellTwo";
cell = [tableViewtwo dequeueReusableCellWithIdentifier:CellIdentifier2];
if (cell==nil) {
cell=[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier2];
}
UILabel * dateLabelOfTableViewTwo = (UILabel*)[cell viewWithTag:211];
dateLabelOfTableViewTwo.text = [dateArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
UILabel *venueLabelOfTableViewTwo=(UILabel*)[cell viewWithTag:214];
venueLabelOfTableViewTwo.text=[venueArrayLabelInTableViewTwo objectAtIndex:indexPath.row];
}
return cell;
}

I have the following implementation, where I am adding a footerview as a customcell. However, if there is no content, I do not want to show the last cell, if there is I want to show it.
In my current implementation, it always displays the last cell.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return [self.adminOrderElements count];
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return adminOrderElements[section].products.count + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}
There is one option that you can make cellHeight to 0.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
if(CHECK_IF_NO_CONTAIN)
return 0;
return 40;// Normal height as you want
}
I think you can add condition in else clause like if certain condition is met then you want to display this cell other wise not...
if (indexPath.row < adminOrderElements[indexPath.section].products.count)
{
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier forIndexPath:indexPath];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier];
}
NSArray * tempArray = adminOrderElements[indexPath.section].products;
cell.textLabel.text = [[tempArray objectAtIndex:indexPath.row] objectForKey:#"productname"];
return cell;
}
else //Here add your condition here if you have content for the section like I think this condition might work [adminOrderElements[indexPath.section].notes length]>0
{
static NSString *CellIdentifier = #"FooterCell";
FooterTableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil)
cell = [[FooterTableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
if(adminOrderElements[indexPath.section].expanded && [adminOrderElements[indexPath.section].notes length]>0)
{
cell.footerLabel.text = [NSString stringWithFormat:#"Notes: %#", adminOrderElements[indexPath.section].notes];
}
else
{
cell.heightConstraints.constant = 1;
cell.footerLabel.text = #"";
}
return cell;
}
}
Its quite simple with UITableView delegate
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if (dataObjects.count == 0){
return 0;
}
return dataObjects.count;
}
I have an array of names that I'm showing via tableview. You can select up to a total of 3 names, and you cannot re-select the same names. To do this I implemented the following code in cellForRowAtIndexPath:. When I run the code the names come up fine, but there are multiple red cells with names that I did not select.
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"TableCell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
NSString *sectionTitle = [nameSectionTitles objectAtIndex:indexPath.section];
NSArray *sectionNames = [names objectForKey:sectionTitle];
NSString *name = [sectionNames objectAtIndex:indexPath.row];
cell.textLabel.text = name;
if ([name isEqualToString: self.name1] || [name isEqualToString: self.name2] || [name isEqualToString: self.name3]) {
[cell setUserInteractionEnabled:NO];
cell.backgroundColor = [UIColor redColor];
cell.accessoryType = UITableViewCellAccessoryNone;
}
return cell;
}
Reading a similar problem here, they were saying that it's because the cells are being reused - but if this were true, how is the tableview still displaying the correct names in the correct position?
I tried to simplify the code into this, and still to no avail, there were multiple red cells.
myIP = [NSIndexPath indexPathForRow:0 inSection:0];
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"TableCell";
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell...
NSString *sectionTitle = [nameSectionTitles objectAtIndex:indexPath.section];
NSArray *sectionNames = [names objectForKey:sectionTitle];
NSString *name = [sectionNames objectAtIndex:indexPath.row];
cell.textLabel.text = name;
if (indexPath == myIP) {
cell.backgroundColor = [UIColor redColor];
}
return cell;
}
I can post a screenshot if needed. Note: The intended names were correctly labeled with red.
The issue is happening due to cell re-using. When a cell with red background is re-used it'll still be in red background, you are not re-setting it anywhere in your code. You need to put a else case to your if condition used in cellForRowAtIndexPath: method.
if ([name isEqualToString: self.name1] || [name isEqualToString: self.name2] || [name isEqualToString: self.name3])
{
[cell setUserInteractionEnabled:NO];
cell.backgroundColor = [UIColor redColor];
cell.accessoryType = UITableViewCellAccessoryNone;
}
else
{
[cell setUserInteractionEnabled:YES];
cell.backgroundColor = [UIColor clearColor];
// Other stuffs
}
I am new to swift.
How can I set IndentationLevel in UITableViewCell?
I have already achieved through Objective C, but I am not able to achieve through Swift.
EDIT:
- (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] ;
}
cell.textLabel.text=[[self.menuTableAr objectAtIndex:indexPath.row] valueForKey:#"name"];
[cell setIndentationLevel:[[[self.menuTableAr objectAtIndex:indexPath.row] valueForKey:#"level"] intValue]];
return cell;
}
Thanks
Assume that valueForKey will return a NSNumber Object
Try
let level = self.menuTableAr.objectAtIndex(indexPath.row).valueForKey("level") as! NSNumber
cell.indentationLevel = Int(level.intValue)
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;
}
