I have a UITableView and for the life of me I can't hide the header and all the footer. I have tried multiple methods posted on here.
I want to hide the white space on top and bottom of the populated rows.
- (void)viewDidLoad
{
[super viewDidLoad];
// Do any additional setup after loading the view.
//Disable Scrolling in TableView
self.tableView.scrollEnabled = NO;
//Get rid of unpopulated rows
self.tableView.tableFooterView = [[UIView alloc] init];
//Hide UITableViewHeader
self.tableView.tableHeaderView = [[UIView alloc] init];
//Populate Table with Test Data
[self testTableView];
}
It looks like your UITableView's layout frame is not getting properly adjusted. Since I am not sure if you are using autolayout constraints or autozingmask therefore please try adding following code to your view controller to force your table to size according to the screen.
- (void)viewDidLayoutSubviews {
self.tableView.frame = self.view.frame;
}
Just set the tableviewHeader to nil or if you want to hide section headers just return nil from viewForHeaderInSection and reload the tableData.

My app consists of a deck of cards. Each card itself is created in a class called draggableview. Draggableview has a scrollview, so that the user can scroll through a bunch of images relevant to the card. On the first view, there are buttons, which I created in draggableview.xib and have their methods in the draggableview class. However, as you scroll past the first view, all the other views do not have these buttons.
EDIT:
I've partially solved my problem. In initwithView, I added each button as a subview of draggableview. Now, the buttons appear in all the views of scrollview. In storyboard, I deleted and added new constraints. And in storyboard, the buttons move accordingly. However, in simulator, they're stuck in the right hand corner of the screen.
For this first try, I did this first with one button (review button).
my initWithFrame method:
- (id)initWithFrame:(CGRect)frame
{
self = [super initWithFrame:frame];
if (self) {
[self addSubviewFromNib];
[self setupView];
panGestureRecognizer = [[UIPanGestureRecognizer alloc]initWithTarget:self action:#selector(beingDragged:)];
cardWidth = frame.size.width;
cardHeight = frame.size.height;
type = 0;
panGestureRecognizer.delegate = self;
panGestureRecognizer.cancelsTouchesInView = NO;
_backgroundScrollView.panGestureRecognizer.cancelsTouchesInView = NO;
likeBadge.image = [UIImage imageNamed:#"likeBadge"];
likeBadge.alpha = 0;
likeBadge.layer.zPosition=99;
passBadge.image = [UIImage imageNamed:#"passBadge"];
passBadge.alpha = 0;
passBadge.layer.zPosition=99;
self.backgroundScrollView.contentSize = self.bounds.size;
[self addSubview: reviewButton];
[self addGestureRecognizer:panGestureRecognizer];
}
return self;
}
How it looks in simulator:
In addition to adding each button as a subview of draggableView in initWithFrame, I also added each button's constraints programmatically. For some reason, this allowed me to move the buttons around (whereas nothing in storyboard was successful) and now they're on all the views of scrollview.
I am creating a UITableView with custom UITableViewCells. iOS 7's new delete button is causing some problems with the layout of my cell.
If I use the "Edit" button, which makes the red circles appear I get the problem, but if I swipe a single cell it looks perfect.
This is when the Edit button is used:
[self.tableView setEditing:!self.tableView.editing animated:YES];
This is when I swipe a single cell:
As you can se my labels overlaps the delete button in the first example. Why does it do this and how can I fix it?
try using the accessoryView and editingAccessoryView properties of your UITableViewCell, instead of adding the view yourself.
If you want the same indicator displayed in both editing and none-editing mode, try setting both view properties to point at the same view in your uiTableViewCell like:
self.accessoryView = self.imgPushEnabled;
self.editingAccessoryView = self.imgPushEnabled;
There seems to be a glitch in the table editing animation in IOS7, giving an overlap of the delete button and the accessoryView when switching back to non-editing state. This seems to happen when the accesoryView is specified and the editingAccessoryView is nil.
A workaround for this glitch, seems to be specifying an invisible editingAccessoryView like:
self.editingAccessoryView =[[UIView alloc] init];
self.editingAccessoryView.backgroundColor = [UIColor clearColor];
The problem is that in edit mode the cell's contentView changes in size. So either you have to override layoutSubviews in your cell and support the different frame sizes
- (void) layoutSubviews
{
[super layoutSubviews];
CGRect contentFrame = self.contentView.frame;
// adjust to the contentView frame
...
}
or you take the bait and switch to autolayout.
First I thought setting contentView.clipsToBounds to YES could be an ugly workaround but that does not seem to work.
I've resolved this problem with set up constraints without width only leading and trailing
As tcurdt mentioned, you could switch to autolayout to solve this issue. But, if you (understandably) don't want to mess with autolayout just for this one instance, you can set the autoresizingMask and have that turned automatically into the appropriate autolayout constraints.
label.autoresizingMask = UIViewAutoresizingFlexibleWidth;
Just use this method in your custom TableViewCell class you can get the perfect answer,
Here self is UITableviewCell
- (void)layoutSubviews {
[super layoutSubviews];
for (UIView *subview in self.subviews) {
for (UIView *subview2 in subview.subviews) {
if ([NSStringFromClass([subview2 class]) isEqualToString:#"UITableViewCellDeleteConfirmationView"]) { // move delete confirmation view
[subview bringSubviewToFront:subview2];
}
}
}
}
And if any one want to adjust the Delete Button Size, Use the following Code
- (void)layoutSubviews {
[super layoutSubviews];
for (UIView *subview in self.subviews) {
for (UIView *subview2 in subview.subviews) {
if ([NSStringFromClass([subview2 class]) isEqualToString:#"UITableViewCellDeleteConfirmationView"]) { // move delete confirmation view
CGRect rect = subview2.frame;
rect.size.height = 47; //adjusting the view height
subview2.frame = rect;
for (UIButton *btn in [subview2 subviews]) {
if ([NSStringFromClass([btn class]) isEqualToString:#"UITableViewCellDeleteConfirmationButton"]) { // adjusting the Button height
rect = btn.frame;
rect.size.height = CGRectGetHeight(subview2.frame);
btn.frame = rect;
break;
}
}
[subview bringSubviewToFront:subview2];
}
}
}
}
Best way to remove this problem is that add an image in cell and set it in Backside.
UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"bgImg.png"]];
imageView.frame = CGRectMake(0, 0, 320, yourCustomCell.frame.size.height);
[yourCustomCell addSubview:imageView];
[yourCustomCell sendSubviewToBack:imageView];
If your text would overlap the delete button then implement Autolayout. It'll manage it in better way.
One more case can be generate that is cellSelectionStyle would highlight with default color. You can set highlight color as follows
yourCustomCell.selectionStyle = UITableViewCellSelectionStyleNone;
Set your table cell's selection style to UITableViewCellSelectionStyleNone. This will remove the blue background highlighting or other. Then, to make the text label or contentview highlighting work the way you want, use this method in yourCustomCell.m class.
- (void)setHighlighted:(BOOL)highlighted animated:(BOOL)animated
{
if (highlighted)
self.contentView.backgroundColor = [UIColor greenColor];
else
self.contentView.backgroundColor = [UIColor clearColor];
}
I hope you understand it in a better way.
Bringing to front UITableViewCellDeleteConfirmationView in the layoutSubviews of the custom cell works for me on iPhone, but not on iPad.
I have a UITableView in the master part of a splitViewController for the iPad, and in this case
the frame of the UITableViewCellDeleteConfirmationView is (768 0; 89 44), instead of (320 0; 89 44)
So I resize the frame in the layoutSubviews method and this works for me
- (void)layoutSubviews {
[super layoutSubviews];
for (UIView *subview in self.subviews)
{
for (UIView *subview2 in subview.subviews)
{
if ([NSStringFromClass([subview2 class]) isEqualToString:#"UITableViewCellDeleteConfirmationView"])
{
CGRect frame = subview2.frame;
frame.origin.x = 320;
subview2.frame = frame;
[subview bringSubviewToFront:subview2];
}
}
}
}
If you are putting content in the UITableViewCell's contentView, be sure you use self.contentView.frame.size.width and not self.frame.size.width in layoutSubviews.
self.frame expands width in editing mode, and will cause any content on the right to extend past the bounds of the contentView. self.contentView.frame stays at the correct width (and is what you should be using).
Try this: Might be you are setting cell setBackgroundImage in cellForRowAtIndexPath (Delegate Method). Do not set this here. Set your image in:
-(void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath { cell.backgroundColor=[UIColor colorWithPatternImage:[UIImage imageNamed:#"cellList.png"]]; }
Enjoy Coding.
My solution is to move whole contentView to the left when Delete button showing:
override func layoutSubviews() {
super.layoutSubviews()
if editingStyle == UITableViewCellEditingStyle.Delete {
var rect = contentView.frame
rect.origin.x = self.showingDeleteConfirmation ? -15 : 38
contentView.frame = rect
}
}
I want to be able to set the size of my tableview depending on what the content is. I would think i could do this in prepareForSegue, since my tableview appears as a popover, if a button is pressed in my rootViewController. So what i'm trying is to set the explicit size, like i can do in storyboard, but i want to do it programmatically. I have tried self.tableview.frame.size, but it get an error, which says it's not assignable?
if([[segue identifier] isEqualToString:#"tagView1"])
{
TagTableViewController *tvc = [segue destinationViewController];
tvc.tableView.frame = CGRectMake(tvc.tableView.frame.origin.x, tvc.tableView.frame.origin.y , 100, 100);
}
In the TVC's viewDidLoad:
- (void)viewDidLoad {
[super viewDidLoad];
self.clearsSelectionOnViewWillAppear = NO;
// Change to what you need
self.contentSizeForViewInPopover = CGSizeMake(150.0, 250.0);
}
You have to set the whole frame. And if you want origin to stay the same do this:
self.tableview.frame = CGRectMake(self.tableview.frame.origin.x, self.tableview.frame.origin.y, __width__, __height__);
Try to set size of table in vieDidAppear:
in TVC .
Like:
-(void)viewDidAppear:(BOOL)animated {
[super viewDidAppear:animated];
[self.tableView setFrame:CGRectMake(self.tableView.frame.origin.x, self.tableView.frame.origin.y, self.tableView.frame.size.width, self.tableView.frame.size.height - 50)];
}
Try self.tableview.frame = (CGRect){self.tableview.frame.origin, newSize};
Which is the same as self.tableview.frame = CGRectMake(self.tableview.frame.origin.x, self.tableview.frame.origin.y, newSize.width, newSize.height);, just shorter.
You aren't supposed to directly set the size, because other objects observing the view's frame won't be notified in that case.
For the first time working with CorePlot (after a couple of hours trying to set it up :P )
on my view, i have a tableview. when a certain IBAction is called i want to show another view (a graph) instead of the tableview.
my approach was to add a subview with the same size to the tableview. it works fine to display the graph, but when i remove the graphs view from [table subviews] the tableview does not reappear.
note:
expenseTable: my tableView
hasSubView: (BOOL) that indicates if a graph is shown right now or not
code
-(IBAction)displayDayBalanceGraph:(id)sender{
if (hasSubView) {
[[expenseTable subviews] makeObjectsPerformSelector: #selector(removeFromSuperview)];
NSLog(#"%#",expenseTable.subviews);
}
else{
[self initializeMonthArray];
CPTGraphHostingView *host = [self buildGraphView];
[expenseTable addSubview:host];
CPTXYGraph *graph = [[CPTXYGraph alloc ]initWithFrame:host.frame];
host.hostedGraph = graph;
CPTScatterPlot *plot = [[CPTScatterPlot alloc]init ];
plot.dataSource = self;
[graph addPlot:plot];
[expenseTable reloadData];
hasSubView = !hasSubView;
}
}
-(CPTGraphHostingView *)buildGraphView{
CPTGraphHostingView *view = [[CPTGraphHostingView alloc]initWithFrame:CGRectMake(0, 0, 312, 260)];
[view setBackgroundColor:[self grayColor]];
return view;
}
1st Screenshot: TableView displayed
2nd Screenshot: GraphView displayed
sidenote: this is a sampleplot =)
3rd Screenshot: GraphView dismissed
has anyone an idea what i missed? (or messed ;) )
It's not generally a good idea to add views as subviews of UITableView.
Instead, you could either remove the table view and replace it with the Core Plot view:
[tableView removeFromSuperview];
[containerView addSubview:corePlotView];
Make sure you have a reference to the table view somewhere or it will be released.
I need to implement a headerview with specific size and gradient. I have to insert images in certain cells of the headerview.Tried to create the cells for the headerview using the following code,but i was not able to customize the headerview.
[[tableColumn headerCell] setImage:[NSImage imageNamed:#"sampleHeader"]];
If I use the overridden subclass of headerview, I was not able to view the images or text in the header cell.Please provide me any pointers to solve this issue.
I was able to insert images and text by subclassing the NSTableHeaderCell.How to increase height of the NSTableHeaderView?
If I subclass both NSTableHeaderView and NSTableHeaderCell , was not able to view anything in the
headercell.I used the following code for setting headerview and headercell
[tableView setHeaderView:CustomHeaderView];
[tableColumn setHeaderCell:[[[CustomHeaderTableCell alloc] initImageCell:
[NSImage imageNamed:#"sample"]]autorelease]];
I have the same issue as given in the below url
http://lists.apple.com/archives/cocoa-dev/2002/Jun/msg00331.html
You don't need to subclass NSTableHeaderView.
I was able to change the height of the header view using the following snippet in the controller class:
-(void)awakeFromNib {
NSRect frame = tableView.headerView.frame;
frame.size.height = 26;
tableView.headerView.frame = frame;
}
It should be noted that the scroll view takes care of the layout. It automatically changes the frame of the headerView as necessary, but leaves the height intact. Resizing the clip view etc as suggested in the other answer is not necessary.
You can also create a NSTableHeaderView object, initialize it with a frame(rect with height and width) and set that NSTableHeaderView object to your table view.
NSTableHeaderView *tableHeaderView = [[NSTableHeaderView alloc] initWithFrame:NSMakeRect(0, 0, 120, 60)];
[myTableView setHeaderView:tableHeaderView];
[tableHeaderView release];
Following link helped me in solving the issue.

You need to set the Frame for NSClipView, NSTableHeaderView and the CornerView
This is how I implemented the same in Code.
for(NSView * subview in [topScrollView subviews])
{
for(NSView * subSubView in [subview subviews])
{
if([[subSubView className] isEqualToString:#"NSTableHeaderView"] && [[subview className] isEqualToString:#"NSClipView"])
{
[subSubView setFrameSize:NSMakeSize(subSubView.frame.size.width, subSubView.frame.size.height+5)];//HeaderView Frame
[subview setFrameSize:NSMakeSize(subview.frame.size.width, subview.frame.size.height+5)];//ClipView Frame
}
}
if ([[subview className] isEqualToString:#"_NSCornerView"])
{
[subview setFrameSize:NSMakeSize(subview.frame.size.width, subview.frame.size.height+5)]; //CornerView Frame
}
}
