MY UITableview Group style only showing one value from the array of 4 elements.
in viewdidload i add following array
_displayThemeItems=[[NSArray alloc]initWithObjects:#"Default",#"Night",#"Sepia" ,#"Blue" ,nil];
_displayThemeIcons=[[NSArray alloc]initWithObjects:[UIImage imageNamed:#"day.png"],[UIImage imageNamed:#"night.png"],[UIImage imageNamed:#"sepia.png"], [UIImage imageNamed:#"blue.png"],nil];
and my table delegate methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [_displayThemeItems count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier=#"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// No cell available - create one.
if(cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:CellIdentifier];}
NSLog(#"rray%#",_displayThemeItems);
cell.textLabel.text = [_displayThemeItems objectAtIndex:indexPath.row];
cell.imageView.image=[_displayThemeIcons objectAtIndex:indexPath.row];
return cell;
}
Your code look fine to me, the only the only reason that I can think amy effect the result you see is how you set up your table view.
Make sure that your table view frame is bug enough to show the 4 items, and make sure you set the tabe view data source.
Add the "}" just before the return such that the code where you set the title and image comes under the "if" statement.

I am developing Iphone Application.Using Three table view on Single viewcontroller. value show on those tableview's on single array but problem is that those array value show on first tableview not on other two tableview's. please help Thanks in advance
code..
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [_arrayResult count];
}
- (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];
}
MEObject *obj = [_arrayResult objectAtIndex:indexPath.row];
if (tableView == _tableView) {
cell.textLabel.text= obj.emp_client_name;
}
if (tableView == _secondTableView) {
cell.textLabel.text= obj.emp_event_name;
}
if (tableView == _thirdTableView) {
cell.textLabel.text=obj.emp_client_name;
}
return cell;
}
Please cross check if you are setting datasource and delegates of all 3 tables to viewcontroller.
When you set your _arrayResult, you need to reload all 3 table view
_arrayResult = #[a,b,c];
[table1 reloadData];
[table2 reloadData];
[table3 reloadData];
After once you set the datasource/Delegate to the all three tableview. I haven't seen any datasource allocation as per your tableview. Like
if tableview == tableview1 {
Return first array
}
Can you please try giving name to those tableview on outlet and then for each datasource and delegates function call as per your requirement but before check which tableview is displayed.
I have added tableview on top of UIViewController and I have also implemented the UITableViewDataSource and UITableViewDelegate methods
For some reason, I am not getting the value out of didSelectRowAtIndexPath. I get the expected value of indexPath.row but the selectedCell.textLabel.text returns nil.
I am not able to figure out what may be the problem. I am using the dynamic table.
//Array of multiple objects is filled through the delegated arrays and the arrays are properly filled.
#pragma mark - Table view data source
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
// Return the number of rows in the section.
return _arrayForMultipleObjects.count;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cell" forIndexPath:indexPath];
array = [[NSMutableArray alloc]init];
// Configure the cell...
_singleSelectionLabel= (UILabel *) [cell viewWithTag:2];
_singleSelectionLabel.text=[self.arrayForMultipleObjects objectAtIndex:indexPath.row];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
NSString *valu ;
NSLog(#"%i count",indexPath.row);
UITableViewCell *selectedCell = [tableView cellForRowAtIndexPath:indexPath];
NSString *cellText = selectedCell.textLabel.text;
NSLog(#"%#",cellText);
//Here cellText is null
if([tableView cellForRowAtIndexPath:indexPath].accessoryType==UITableViewCellAccessoryNone)
{ [tableView cellForRowAtIndexPath:indexPath].accessoryType=UITableViewCellAccessoryCheckmark;
valu = cellText;
}
NSLog(#"%#",valu);
}
If you are using storyboard then the default cell style of table cells is Custom which gives you a blank cell where you can add other types of controls to it.
If you dragged a label onto the cell and changed its text, then you are likely using a Custom style of UITableViewCell.
The property textLabel is only available on cells of types other than Custom, such as Basic, or Detailed.
Please double check if this is the case for you.
Edit: As ready suggested you can fetch the text like this:
self.arrayForMultipleObjects[indexPath.row]

Is there a way to make UITableView cells in iOS 7 not have a line break in the separator?

Closed 8 years ago.
Hi
I have a UITableView in my class and when i tried to load the contents am getting a screen like this
Below the white box am not able to see the horizodal separator line , Please help me.
My code:
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1; //count of section
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [names count]; //count number of row from counting array hear cataGorry is An Array
}
- (UITableViewCell *)tableView:(UITableView *)tableView
cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *MyIdentifier = #"service";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if (cell == nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault
reuseIdentifier:MyIdentifier]
;
}
// Here we use the provided setImageWithURL: method to load the web image
// Ensure you use a placeholder image otherwise cells will be initialized with no image
cell.imageView.frame=CGRectMake(5,10,50,60);
cell.imageView.image=[imaages objectAtIndex:indexPath.row];
cell.textLabel.text = [names objectAtIndex:indexPath.row];
cell.backgroundColor=[UIColor clearColor];
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
{
return 80;
}
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath{
}
write in your view did load
In iOS 7 and later, cell separators do not extend all the way to the edge of the table view.This property sets the default inset for all cells in the table, much like rowHeight sets the default height for cells. It is also used for managing the “extra” separators drawn at the bottom of plain style tables.
// Do any additional setup after loading the view.
if ([_tableView respondsToSelector:#selector(setSeparatorInset:)]) {
[_tableView setSeparatorInset:UIEdgeInsetsZero];
}
I'm working on my first app and I'm kind of new to Objective-C, I want to make it so when someone types in a text field then presses a button it will save it to a table view. Does anyone know how to do this or know any tutorials.
all you have to do is everytime you press the button you'll refresh/update your tableview.
- (IBAction)buttonPressed:(id)sender {
NSString *textNameToAdd = yourTextField.text;
[containerArrayForTableView addObject:textNameToAdd];
[myTableView reloadData];
}
// UITABLEVIEW DELEGATES
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
// Return the number of sections.
return 1;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{
// Return the number of rows in the section.
// Usually the number of items in your array (the one that holds your list)
return [containerArrayForTableView count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
//Where we configure the cell in each row
static NSString *CellIdentifier = #"Cell";
UITableViewCell *cell;
cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
}
// Configure the cell... setting the text of our cell's label
cell.textLabel.text = [containerArrayForTableView objectAtIndex:indexPath.row];
return cell;
}
refer here if you are having trouble configuring with UITableView.
These are some good tutorials for you..

Happy coding.
EDIT:
Here what i made for you:
Simple Demo With TextField & TableView
EDIT 2:
Simple Demo With 2 TextFields & 2 TableViews
I'm basically making a settings view on my app and I'm using a static table for it. So I divided the table into 3 sections each with one cell. Not programmatically I can easily label each cell and it works but programmatically I'm not able to initialize each cell. I can only initialize the first cell that gets repeated across the 3 sections. I would like a way to initialize a cell for each section but I can't find a method or a way to do that. My tableview also has reuseIdentifiers but it doesn't seem like the UITableViewController recognizes it.
This is what I have done so far.
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
#warning Potentially incomplete method implementation.
// Return the number of sections.
return 3;
}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
#warning Incomplete method implementation.
// Return the number of rows in the section.
return 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"EditProfile";
//UITableViewCell *cell = nil; //[tableView dequeueReusableCellWithIdentifier:CellIdentifier];
// Configure the cell...
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier];
// More initializations if needed.
}
//Observations *currentList = [self.teacherNames objectAtIndex:indexPath.row];
cell.textLabel.text = #"Hey";
//return cell;
return cell;
}
But what I want is the cell in the first section to be labeled: Edit Profile, the second one: Invite and the third:Logout
You have to make a condition for how to handle each different section within the table view.
if (indexPath.section == 0) {
cell.textLabel.text = #"Edit Profile";
}else if (indexPath.section == 1) {
cell.textLabel.text = #"Invite";
}else if (indexPath.section == 2) {
cell.textLabel.text = #"Log out";
}......
Check out the tableView delegate methods:
-(NSString*)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section;
- (UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section;
-(CGFloat)tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section;
(IF you're wanting to label the section headers and not the cells in the sections themselves)
