I have a tableView with custom cell and when i select a row nothing is happening?
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
return [arrayOfExpectations count];
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
CustomTableViewCell *cell = [self.tableView dequeueReusableCellWithIdentifier:#"CustomCell"];
Expectations *expectation = [arrayOfExpectations objectAtIndex:indexPath.row];
cell.quoteLabel.text = expectation.expText;
return cell;
}
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath {
// Calculate a height based on a cell
if(!self.customCell) {
self.customCell = [self.tableView dequeueReusableCellWithIdentifier:#"CustomCell"];
}
Expectations *expectation = [arrayOfExpectations objectAtIndex:indexPath.row];
self.customCell.quoteLabel.text = expectation.expText;
[self.customCell layoutIfNeeded];
// Get the height for the cell
CGFloat height = [self.customCell.contentView systemLayoutSizeFittingSize:UILayoutFittingCompressedSize].height;
// Padding of 1 point (cell separator)
CGFloat separatorHeight = 1;
return height + separatorHeight;
}
- (CGFloat)tableView:(UITableView *)tableView estimatedHeightForRowAtIndexPath:(NSIndexPath *)indexPath {
return 100;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
Expectations *expectation = [arrayOfExpectations objectAtIndex:indexPath.row];
expParentID = expectation.expID;
NSLog(#"PrevID = %#", prevexpParentID);
NSLog(#"NewID = %#", expParentID);
[self loadData];
}
Selecting option was blocked. Thank you viper king

I am pretty new to Objective-C and I am stuck in this part. I am trying to display the controls the textfield, label, Gradient views, and the Transfer button which are inside the content view of the cell, but it does not appear when I test it out. It only shows "1. Data to operate" twice but no content.. Can someone please help me out with this? I would appreciate it.
Below is how my ViewController looks like:
#implementation CNCTransfersOwnViewController{
}
//#synthesize delegate;
+ (id)instanceFromStoryboard {
return [self instanceFromStoryboardNamed:#"Transfer"];
}
- (void)viewDidLoad {
[super viewDidLoad];
[self setUpUI];
// Do any additional setup after loading the view.
}
- (void)didReceiveMemoryWarning {
[super didReceiveMemoryWarning];
// Dispose of any resources that can be recreated.
}
- (void)setUpUI {
self.navigationBar.topItem.title = #"GO TO SOMEWHERE ELSE";
}
- (NSString *)identifierForCellAtIndexPath:(NSIndexPath *)indexPath {
NSString *identifier = #"";
identifier = #"OPERATION";
return identifier;
}
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
return 1;}
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section {
if(self.tableView == tableView){
return 2;
}else{
return 0;
}
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(self.tableView == tableView){
NSString *identifier = [self identifierForCellAtIndexPath:indexPath];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
return cell;
}
return nil;
}
You need to set the text you want to display in the cellForRowAtIndexPath method:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
if(self.tableView == tableView){
NSString *identifier = [self identifierForCellAtIndexPath:indexPath];
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:identifier forIndexPath:indexPath];
cell.selectionStyle = UITableViewCellSelectionStyleNone;
cell.textLabel.text = #"The text you want to display";
return cell;
}
return nil;
}
I have a tableview which have 4 row. then i want to insert a collectionview into tableview cell and each collectionview have different cell. But i can't do that. can any one help me out or any suggesition?
You can give different CellIdentifiers for every TableViewCell and createa different rows in InterfaceBuilder or inside
cellForRowAtIndexPath
Dont forget to provide dataSource and delegate for every collectionView that you will create for TableViewCell
Pseudocode:
YN Means YourNamespace
YNDataSourceDelegate1* data1;
YNDataSourceDelegate2* data2;
YNDataSourceDelegate3* data3;
YNDataSourceDelegate4* data4;
const NSInteger COLLECTION_VIEW_TAG = 1001;
NSArray* providers=#[data1,data2,data3,data4];
NSArray* rowIds=#[#"row1",#"row2",#"row3",#"row4"];
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:rowIds[indexPath.row]];
UICollectionView * collectionView = (UICollectionView*)[cell viewWithTag:COLLECTION_VIEW_TAG];
collectionView.dataSource = providers[indexPath.row];
return cell;
}

i want to tap the uitableviewcell and its height should increase and than when i tap again on the same cell the size of cell should reduce. The size of custom cell is 293, but it should be 217 in start , when i touch it , it should be 293 and if i touch it again it should go back to 217. The same happens for all the cells. Please see the image links to have a better understanding.

I have a UITableView with UIImage images populated in the cells. I want to be able to add some spacing between each image, and the separator lines because as you can see, some of the images are really close to the separator lines.
I could just modify the images and add spacing for each image, but I'd rather not.
Attached is what I like to achieve with the red arrows.
How can I achieve this?
Thanks.
Added code:
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return [sponsorsLogoArray count];
}
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if ([tableView respondsToSelector:#selector(setSeparatorInset:)])
{
[tableView setSeparatorInset:UIEdgeInsetsZero];
}
if ([tableView respondsToSelector:#selector(setLayoutMargins:)])
{
[tableView setLayoutMargins:UIEdgeInsetsZero];
}
if ([cell respondsToSelector:#selector(setLayoutMargins:)])
{
[cell setLayoutMargins:UIEdgeInsetsZero];
}
}
- (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];
}
// Set cell background color to be transparent as it cannot be achieved via storyboard
cell.backgroundColor = [UIColor clearColor];
// Populate each cell with image from array
cell.imageView.image = [UIImage imageNamed:[sponsorsLogoArray objectAtIndex:indexPath.row]];
return cell;

I am facing new problem.In my app, i am getting data by using NSXmlParser.
After parsing data , i am creating UITableview manually.
Here is my code,
-(void) connectionDidFinishLoading:(NSURLConnection *)connection
{
parser = [[NSXMLParser alloc]initWithData:self.cData];
parser.delegate = self ;
[parser parse];
tableView = [[UITableView alloc]initWithFrame:CGRectMake(0, 20, 320, 460) style:UITableViewStylePlain];
tableView.dataSource = self;
tableView.delegate = self;
[self.view addSubview:tableView];
}
This is my delegates methods
- (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView
{
return 1;
}
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return eventName.count;
}
-(void)tableView:(UITableView *)tableView didDeselectRowAtIndexPath:(NSIndexPath *)indexPath
{
}
-(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]autorelease];
}
for (int i=0; i < eventName.count; i++)
{
cell.textLabel.text = [eventName objectAtIndex:i];
NSLog(#"%#",cell.textLabel.text);
}
return cell;
}
Instead of checking i in the for loop, remove the for loop and look for indexPath.row in-
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
...
cell.textLabel.text = [eventName objectAtIndex:indexPath.row];
...
}
It will be called as many times as the value returned by-
-(NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section{}
