I have a UITableViewCell with a accessorytype detail indicator. When I resize the cell, the cells accessory centers itself horizontally. How can I make it stay on top, and not center itself?
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
customCell *cell = [tableView dequeueReusableCellWithIdentifier:#"cellID" forIndexPath:indexPath];
return cell;
}
I'd prefer doing it in the storyboard if possible, if not, I'm happy to hear how to do it programatically.
My mistake, Actually you can't do any change in default accessoryView of tableView, You need to create a custom accessoryView for your cell. Just ignore the accessory type because it will not longer matters once you create your own accessoryView.
try this code in CellForRowAtIndexPath
if(!cell.accessoryView)
{
UIImage *image = [UIImage imageNamed:#"image.png"];
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect frame = CGRectMake(0.0, 0.0, image.size.width, image.size.height);
button.frame = frame;
[button setBackgroundImage:image forState:UIControlStateNormal];
//add target if necessary
[button addTarget:self action:#selector(checkButtonTapped:event:) forControlEvents:UIControlEventTouchUpInside];
//apply customisations
button.backgroundColor = [UIColor clearColor];
cell.accessoryView = button;
}

i m having a simple section table view. I have added a button at the left side of image.This button is selectable.Only one button (each cell have single button of same type) can be selected at a time and selected button background image changes to a specific selected image, others button back ground image changes to deselect image.If you tap again on selected image it remains selected.
How ever i am not getting correct behaviour.
code:
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
// UITableViewCell *cell=nil;
CustomCellMasterCustomer *cell=nil;
static NSString *cellIdentifier=#"Locations";
Customer *mCustomer;
cell=[tableView dequeueReusableCellWithIdentifier:cellIdentifier];
if(cell==nil){
// cell=[self reusableContentWithIdentifier:cellIdentifier];
cell=(CustomCellMasterCustomer *)[self reusableContentWithIdentifier:cellIdentifier];
}
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
button.tag = indexPath;
[button setBackgroundImage:[UIImage imageNamed:#"cellLeftImageDisabled.png"] forState:UIControlStateNormal];
[button setFrame:CGRectMake(10, 5, 36, 30)];
[button addTarget:self action:#selector(viewDetail:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
cell.aCustomer = mCustomer;//alok added
if (indexPath == self.mPreviousIndex)
{
[button setBackgroundImage:[UIImage imageNamed:#"cellLeftImageEnabled.png"] forState:UIControlStateNormal];
}
else
{
[button setBackgroundImage:[UIImage imageNamed:#"cellLeftImageDisabled.png"] forState:UIControlStateNormal];
}
return cell;
}
-(void)viewDetail:(id)sender
{
CGPoint buttonOrigin = [sender frame].origin;
// this converts the coordinate system of the origin from the button's superview to the table view's coordinate system.
CGPoint originInTableView = [self.allCustomerTable convertPoint:buttonOrigin fromView:[sender superview]];
// gets the row corresponding to the converted point
NSIndexPath *rowIndexPath = [self.allCustomerTable indexPathForRowAtPoint:originInTableView];
CustomCellMasterCustomer *cell = (CustomCellMasterCustomer *)[self.allCustomerTable cellForRowAtIndexPath:rowIndexPath];
[self fillDetailViewWithCustomerInformation:cell.aCustomer];
//change button background image
UIButton *btn = (UIButton *)sender;
[btn setBackgroundImage:[UIImage imageNamed:#"cellLeftImageEnabled.png"] forState:UIControlStateNormal];
self.mPreviousIndex = rowIndexPath;
[self.allCustomerTable reloadData];
}
what wrong i am doing,
any suggestion
Try this. Because indexpath always recreate with same row and section number. It won't same as previous.
if (indexPath.row == self.mPreviousIndex.row && indexPath.section == self.mPreviousIndex.section)
{
[button setBackgroundImage:[UIImage imageNamed:#"cellLeftImageEnabled.png"] forState:UIControlStateNormal];
}
And this two line of code, not needed anymore
/* UIButton *btn = (UIButton *)sender;
[btn setBackgroundImage:[UIImage imageNamed:#"cellLeftImageEnabled.png"] forState:UIControlStateNormal];*/
You should not add a button out side the if block. In UITableView cells will be reused, if the cell is reused and at already has a button added to contentView then you should not add one more on top of it. so create a custom cell and make the buttion instance visible outside the class by declaring the buttion property in customCell.h. Now check the condition -
if (selected)
{
cell.button.backgroundImage = selectedImage;
}
else
{
cell.button.backgroundImage = unselectedImage;
}
I have a image view(tapping on which i get a popover) inside a cell associated in table views.
Log element tree captures the static text 'Picture' but it doesn't show associated image view with it.
My flow is like tables -> cells( have around 4 cells which are static texts)
These cells in turn have textfields attached with them.
cell1-> textfields1
cell2-> textfields2
cell3-> textfields3
cell4-> has just an image.
How do I access this Image?
var imageId = table[0].cells()[4];
imageId.images();
Dis not return anything.
i think u can configure ur cell 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];
}
CGRect Frame4 = CGRectMake(10.0, 30.0, 50.0, 40.0);
UIButton *button = [UIButton buttonWithType:UIButtonTypeDetailDisclosure];
button.frame = Frame4;
[button setTitle:#"Click" forState:UIControlStateNormal];
button.backgroundColor = [UIColor grayColor];
[button addTarget:self
action:#selector(buttonPressed:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:button];
return cell;
}
and then add button action event :
(IBAction)buttonPressed:(UIButton *)sender{
// in sender u can get which button is pressed
//do something
}
please replace " UIButtonTypeDetailDisclosure " for ur desire image Button
I'm trying to add subviews to a view according to the cell of the tableview .. i've done this code already
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
VerseCell *cell = (VerseCell *)[tableView cellForRowAtIndexPath:indexPath];
rowSelected = indexPath.row;
CGRect cellRect = cell.frame;
UIView *cellView =[[UIView alloc]initWithFrame:CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70)];
UIImageView* background =[[UIImageView alloc]initWithImage:[UIImage imageNamed:#"FavoritePanelBackground"]];
background.frame =CGRectMake(cellRect.origin.x+4, cellRect.origin.y+15, cellRect.size.width-20, 70);
[cellView addSubview:background];
[cellView setBackgroundColor:[UIColor redColor] ];
UIButton * favoritsB = [[UIButton alloc]initWithFrame:CGRectMake(cellRect.origin.x+10, cellRect.origin.y+15, 60, 40)];
[favoritsB setBackgroundImage:[UIImage imageNamed:#"MofadalatNormalIcon.png"] forState:UIControlStateNormal];
[favoritsB setBackgroundImage:[UIImage imageNamed:#"MofadalatTappedIcon.png"] forState:UIControlStateHighlighted];
[favoritsB addTarget:self action:#selector(favorite) forControlEvents:UIControlEventTouchUpInside];
[cellView addSubview:favoritsB];
cellView=nil;
}
the problem is .. that this code work as expected in the first row only.. and when click on next cell it shows the main UIVIew (which i've mark with red background) in the expected position while the sub views of it is going really far down... so what i'm doing wrong here.. and is there another approach for what i'm doing if that will not work?
Where are you trying to add these view? Inside the table view cell? If so, you never add cellView as a subview of cell. IF that's what you're trying to do, add this line just above cellView = nil:
[cell addSubview:cellView];
I've tried a bunch of stuff - adding a button from the object browser, changing attributes, searching the web, but no luck. Essentially, I'd like to do --in the storyboard--:
where you see "add to contacts" "share location" and "add to bookmarks".
You should create a UITableViewCell whose contentView holds 3 separate UIButtons.
To do this programmatically, in your tableView:cellForRowAtIndexPath: data source method, you can use code similar to the following:
- (UITableViewCell*) tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
static NSString* identifier = #"cell";
UITableViewCell* cell = [tableView dequeueReusableCellWithIdentifier:identifier];
if (!cell) {
cell = [[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:nil];
cell.backgroundColor = [UIColor clearColor];
UIButton* button1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
UIButton* button2 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
UIButton* button3 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
button1.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 0, 0, 250));
button2.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 125, 0, 125));
button3.frame = UIEdgeInsetsInsetRect(cell.contentView.bounds, UIEdgeInsetsMake(0, 250, 0, 0));
button1.autoresizingMask = UIViewAutoresizingFlexibleRightMargin;
button2.autoresizingMask = UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleLeftMargin;
button3.autoresizingMask = UIViewAutoresizingFlexibleLeftMargin;
[cell.contentView addSubview:button1];
[cell.contentView addSubview:button2];
[cell.contentView addSubview:button3];
}
return cell;
}
Also, in the tableView:willDisplayCell: method of your delegate, do the following to have the default decoration of the cell totally disappear:
- (void) tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
cell.backgroundView = nil;
}
You should obtain a result very similar to what you posted.
Put the three buttons in a UIView that is 320 pixels wide and say 60 hight, and make that view the footer of your table.
The UITableView is styled using the UITableViewStyleGrouped stye.
The three UIButtons are programmatically added to the tableView.tableFooterView.
Alternatively, you can add three UIButtons to the contentView of the last cell.
Add buttons like:
UIButton *theButton = [UIButton buttonWithType:UIButtonTypeRoundedRect];
theButton.frame = CGRectMake(20, 20, 200, 40);
[theButton setTitle:#"Button" forState:UIControlStateNormal];
[theButton addTarget:self action:#selector(buttonClicked:) forControlEvents:UIControlEventTouchUpInside];
[cell.contentView addSubview:theButton];
Get the button positions correctly using trial and error :)
I'm dynamically adding an accessoryView to my UITableVieCell when it is tapped. It appears to me that the cell highlight is blocking the accessoryView. I don't see my acessoryView until the highlight disappears via tapping a different table cell.
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
[tableView selectRowAtIndexPath:indexPath
animated:YES
scrollPosition:UITableViewScrollPositionNone];
UITableViewCell* cell = [tableView cellForRowAtIndexPath:indexPath];
cell.textLabel.text = #"Loading server stuff";
UIButton *button = [UIButton buttonWithType:UIButtonTypeCustom];
CGRect frame = CGRectMake(0.0, 0.0, 20, 10);
button.frame = frame;
button.backgroundColor = [UIColor redColor];
cell.accessoryView = button;
}
The highlight of a cell swaps the background of all the views within. Place an image of your button with this instead:
- (void)setImage:(UIImage *)image forState:(UIControlState)
That way, the background is swapped, but the image remains on top.
