I am trying to add a pickerView to a row in my table view, but after doing this, all I see is a black rectangle inside the cell.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *MyIdentifier = #"MyIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:MyIdentifier];
if(cell == nil) {
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:MyIdentifier] autorelease];
pickerView = [[[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 0.0, 200, 300)] autorelease];
[cell.contentView addSubview:pickerView];
}
}
I really don't have a clue how to solve this.
Can anyone help me, please?
May be this can help: DateCell with TableViewController

I have a NSTableViewCell which has a ImageView within the cell.
What is needed to control the position of the image within the cell using code?
If you are using subclass of NSTextFieldCell(ImageAndTextCell). you can control positon of image in
- (NSRect)imageRectForBounds:(NSRect)cellFrame method.
You can create custom cell...
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = #"ImageOnRightCell";
UIImageView *photo;
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier]];
cell.accessoryType = UITableViewCellAccessoryDetailDisclosureButton;
photo = [[[UIImageView alloc] initWithFrame:CGRectMake(225.0, 0.0, 80.0, 45.0)]];
photo.tag = PHOTO_TAG;
photo.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleHeight;
[cell.contentView addSubview:photo];
} else {
photo = (UIImageView *)[cell.contentView viewWithTag:PHOTO_TAG];
}
return cell;
}
This will look like it....
or u can read this link....

instead of default TableViewCell, create your own custom tableViewCell and position it according to your need.
I used willDisplayCell delegate method to show a custom background image to a UITableViewCell.
- (void)tableView:(UITableView *)tableView
willDisplayCell:(UITableViewCell *)cell
forRowAtIndexPath:(NSIndexPath *)indexPath {
static UIImage* bgImage = nil;
if (bgImage == nil) {
bgImage = [UIImage imageNamed:#"myImage.png"];
}
cell.backgroundView = [[UIImageView alloc] initWithImage:bgImage];
}
When I run the app in the simulator, the background only for the cells that are drawn are changed, is there a way to change all cells' background?
I have worked this code.It's working good .you can try this code.
- (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];
}
cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:#"Cell"] autorelease];
UIImageView *cellBackView=[[UIImageView alloc]initWithFrame:CGRectMake(0, 0, 320, 100)];
cellBackView.backgroundColor=[UIColor clearColor];
cellBackView.image = [UIImage imageNamed:#"list.png"];
cell.backgroundView = cellBackView;
cell.selectionStyle=UITableViewCellSelectionStyleNone;
return cell;
}
You have to set the backgroundView property in the cellForRowAtIndexPath method that creates the cell:
- (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.backgroundView = [[UIImageView alloc] initWithImage:...];
return cell;
}
I added a UIImageview as a subview of UITableViewCell.contentview. It has margins in left and right side of the cell. when rotating device, Autoresizing is not working for me. I am using:
UIImageView *imgviewcellBg=[[UIImageView alloc]initWithFrame:CGRectMake(9, 3, self.view.bounds.size.width-18, 33)];
imgviewcellBg.autoresizesSubviews=UIViewAutoresizingFlexibleWidth;
[cell.contentView addSubview:imgviewcellBg];
Help me. Thanks.
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString *SimpleTableIdentifier = #"SimpleTableIdentifier";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:SimpleTableIdentifier];
if(cell == nil)
{
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:SimpleTableIdentifier]autorelease];
cell.frame = CGRectMake(cell.frame.origin.x, cell.frame.origin.y, tblMyWines.frame.size.width, cell.frame.size.height);
}
UIImageView *imgviewcellBg=[[UIImageView alloc]initWithFrame:CGRectMake(tbl.frame.origin.x+5, 3, tbl.frame.size.width-10.0, 33)];
[cell.contentView addSubview:imgviewcellBg];
return cell;
}
Please, explain me: how to programmatically create an UITextView in UITableViewCell (UITableView has a grouped style). The text view size should be equal to size of the cell.
The UITextView has a gap between its text and its border (top left corner), so I need the correct coordinates to properly place the text view on a cell.
UPDATE: I've solved my question. See my self-answer below. Thanks!
It was simple:
textView.frame = CGRectMake(0, 0, cell.contentView.frame.size.width, cell.contentView.frame.size.height);
Here you go:
- (UITableViewCell *) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:#"Prototype Cell"];
UITextField *textfield;
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleSubtitle
reuseIdentifier:#"Prototype Cell"];
textfield = [[UITextField alloc] init];
[cell.contentView addSubview:textfield];
textfield.tag = TEXT_FIELD_TAG; //Suppose you defined TEXT_FIELD_TAG someplace else
}
else
{
textfield = [self.view viewWithTag: TEXT_FIELD_TAG];
textfield.frame = cell.frame;
}
return cell;
}
Set "contentInset" of UITextView
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *sCellIdentifier = #"cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:sCellIdentifier];
if (!cell)
{
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDetail
reuseIdentifier:sCellIdentifier];
}
UITextView *textView = [UITextView alloc]init];
textView.contentInset = UIEdgeInsetsMake(-8,-8,-8,-8); //Change according ur requirement
textView.frame = cell.frame;
[textView setUserInteractionEnabled:FALSE];
[textView setBackgroundColor:[UIColor clearColor]];
[cell.contentView addSubView:textView];
return cell;
}
I am using an image to display the whole content of a UITableViewCell and it's set using the backgroundView property.
My problem is that it is always scaled to fit the cell. Is there a way to disable scaling in this case, so I can provide the 480 pixel version only and it just gets cropped when orientation is portrait?
I'm doing it like this:
- (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];
}
UIImageView *bgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:#"menu.0%d.large.png", indexPath.row+1]]];
UIImageView *selectedBgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:#"menu.0%d.large.selected.png", indexPath.row+1]]];
cell.backgroundView = bgView;
cell.selectedBackgroundView = selectedBgView;
[bgView release];
[selectedBgView release];
return cell;
}
I tried using two versions of the images to switch between them when orientation is changed. This works so far, too, but it's got the drawback that you always see the scaling while the animation is processed.
Thanks for your help

Set the content mode of your background image views.
bgView.contentMode = UIViewContentModeTopLeft;
selectedBgView.contentMode = UIViewContentModeTopLeft;
This tells the UIImageView to put its image in the top left corner rather than scale it to fit.
I did not try this on the simulator or device, but the following might work:
- (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];
}
// New!
cell.backgroundView.clipsToBounds = YES;
UIImageView *bgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:#"menu.0%d.large.png", indexPath.row+1]]];
UIImageView *selectedBgView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:[NSString stringWithFormat:#"menu.0%d.large.selected.png", indexPath.row+1]]];
// New!
bgView.center = CGPointMake(160, 25); // Adjust the y-Value to be exactly half of the height of your cell
bgView.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin; // Not quite sure whether these two will work, maybe you have to play a little with the Masks
cell.backgroundView = bgView;
cell.selectedBackgroundView = selectedBgView;
[bgView release];
[selectedBgView release];
return cell;
}
Let me know whether you managed to get it running.
- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath
is was you looking for, I think.
