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)

Table is showing the list of countries. But when i tried to retrieve the data its returning null value. I am trying store the cell.textlabel.text into a string but worrying with null
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier:#"MyCell"];
if (cell==nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:#"CellIdentifier"];
}
jsonDict = [newarray objectAtIndex:indexPath.row];
cell.textLabel.text = [jsonDict objectForKey:#"countryName"];
return cell;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView cellForRowAtIndexPath:indexPath];
NSLog(#"country is %#",cell.textLabel.text);
cell.textLabel.text=CountryString;
}
-(void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath {
jsonDict = [newarray objectAtIndex:indexPath.row];
CountryString=[jsonDict objectForKey:#"countryName"]
NSLog(#"country is %#", CountryString);
}
your cell identifier also different
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"cell"; //here mention the correct one use either `MyCell` or `CellIdentifier`
UITableViewCell *cell = (UITableViewCell *)[tableView dequeueReusableCellWithIdentifier: CellIdentifier];
if (cell==nil)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier: CellIdentifier];
}
jsonDict = [newarray objectAtIndex:indexPath.row];
cell.textLabel.text = [jsonDict objectForKey:#"countryName"];
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 got the above error when trying to launch my app second time. First time I got it properly. But when I try to select the tableview, I am getting the error. please help me
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath

{

cell.textLabel.text = [arrayname objectAtIndex:indexPath.row];
cell.textLabel.backgroundColor=[UIColor clearColor];
cell.textLabel.textColor=UIColorFromRGB(0xffffff);
return cell;

I pass an array called userArray which stores another array with strings. This is what I have so far but I know it's wrong. Can someone point me in the right direction?
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier];
}
//Set Up Cell
DataSingleton *sharedData = [DataSingleton sharedData];
for (NSArray *array in sharedData.usersArray){
cell.primaryLabel.text = [array objectAtIndex:1];
cell.secondaryLabel.text = [array objectAtIndex:2];
cell.profileImage = [UIImage imageNamed:#"111-user.png"];
return cell;
}
}
cellForRowAtIndexPath is a UITableViewDataSource method, and it asks the data for single cell only. So, you have to remove a loop, and set up a single cell at once, using indexPath.row as an array index in your DataSingleton
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath{
static NSString *CellIdentifier = #"Cell";
CustomCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if(cell == nil) {
cell = [[CustomCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier];
}
//Set Up Cell
DataSingleton *sharedData = [DataSingleton sharedData];
NSArray *array = [sharedData.usersArray objectAtIndex:indexPath.row];
cell.primaryLabel.text = [array objectAtIndex:1];
cell.secondaryLabel.text = [array objectAtIndex:2];
cell.profileImage = [UIImage imageNamed:#"111-user.png"];
return cell;
}
Also, you should implement tableView:numberOfRowsInSection: to return [[[DataSingleton sharedData] usersArray] count]
So far search on Stack Overflow I havent found a situation that is like mine. Any assistance is greatly appreciated: I keep seeing that if I put a checkmark on Person A, Person H will also have one as well as does a person about 10 away. Basically abut every 10 it repeats a check mark.
Here is my code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{static NSString *CellIdentifier = #"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
cell.textLabel.text =
[NSString stringWithFormat:#"%# %#", [[myArrayOfAddressBooks objectAtIndex:indexPath.row] objectForKey:#"FirstName"],[[myArrayOfAddressBooks objectAtIndex:indexPath.row] objectForKey:#"LastName"]];
cell.detailTextLabel.text =
[NSString stringWithFormat:#"%#", [[myArrayOfAddressBooks objectAtIndex:indexPath.row] objectForKey:#"Address"]];
return cell;
}
In my did select row for index path I have this:
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell;
cell = [self.tableView cellForRowAtIndexPath: indexPath];
if ([[myArrayOfAddressBooks objectAtIndex:indexPath.row] objectForKey:#"emailSelected"] != #"YES")
{
cell.accessoryType = UITableViewCellAccessoryCheckmark;
[[myArrayOfAddressBooks objectAtIndex:indexPath.row] setValue:#"YES" forKey:#"emailSelected"];
}
else
{
cell.accessoryType = UITableViewCellAccessoryNone;
[[myArrayOfAddressBooks objectAtIndex:indexPath.row] setValue:#"NO" forKey:#"emailSelected"];
}
This is due to how UITableView "recycles" UITableViewCell for efficiency purposes, and how you are marking your cells when they are selected.
You need to refresh/set the accessoryType value for every cell you process/create within tableView:cellForRowAtIndexPath:. You properly update the state in your myArrayOfAddressBooks data structure, and you just need to use this information in tableView:cellForRowAtIndexPath:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *CellIdentifier = #"MyCell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle reuseIdentifier:CellIdentifier] autorelease];
}
NSDictionary *info = [myArrayOfAddressBooks objectAtIndex:indexPath.row];
cell.textLabel.text = [NSString stringWithFormat:#"%# %#", [info objectForKey:#"FirstName"],[info objectForKey:#"LastName"]];
cell.detailTextLabel.text = [NSString stringWithFormat:#"%#", [info objectForKey:#"Address"]];
cell.accessoryType = ([[info objectForKey:#"emailSelected"] isEqualString:#"YES"]) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
return cell;
}
Also, unless there is a good reason for saving the state as #"Yes" or #"No" strings, why not save them as [NSNumber numberWithBool:YES] or [NSNumber numberWithBool:NO]? This will simplify your logic when you want to do comparisons versus having to use isEqualToString: all the time.
e.g.
cell.accessoryType = ([[info objectForKey:#"emailSelected"] boolValue]) ? UITableViewCellAccessoryCheckmark : UITableViewCellAccessoryNone;
