In my code i was trying to set label in iCarouselView.My icarousel contains labels and textView so i am trying to set label but it is not setting properly.I have array of months and setting that array of months to each icarousel label, like this.
(UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
if (!view)
{
UIViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PopUpView"];
view = [viewController.view viewWithTag:999];
UILabel *label=(UILabel*)[viewController.view viewWithTag:109];
label.text = [_monthsArray objectAtIndex:index];
CGRect Frame = CGRectMake(view.frame.origin.x, view.frame.origin.y+100, view.frame.size.width, view.frame.size.height);
view.frame = Frame;
}
return view;}
I am loading external view as popUpView in storyBoard and getting label using tag.
And i am returning carousel count as [monthsArray count].
carousel delegate and datasource is also set and reloadData method is also called on iCarousel.
The output which i am getting is something like this.
| January,February,March,November,December|
Please tell me where i am wrong?and what to do now?
Update you code to below one -
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
if (!view){
UIViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"PopUpView"];
view = [viewController.view viewWithTag:999];
CGRect Frame = CGRectMake(view.frame.origin.x, view.frame.origin.y+100, view.frame.size.width, view.frame.size.height);
view.frame = Frame;
}
UILabel *label=(UILabel*)[view viewWithTag:109];
label.text = [_monthsArray objectAtIndex:index];
return view;
}
iCaurosel will take UIView, In your case you are creating a view controller, which is not retained and is dangerous. See if you change it to view via a custom Xib.

I'm trying to design a UITableViewController such that when the user hits the "Search" button on the navigation bar, the table view drops down and a UIView drops down from the navigation bar. Then, when the user taps anywhere outside of the UIView, the UIView should retract and the table view should return to its original position.
Currently, I have the following method that is the selector for the "Search" button. Note - self.searchBar is a custom UIView subclass.
Is there a cleaner/better way to accomplish this? Also I'm not sure how to get rid of the view after the user taps out of the search menu... I'm guessing I should call, [self.searchBar removeFromSuperview]; but not sure in which delegate method to put that line.
Thanks!
- (void)_showSearchMenu
{
CGRect frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height * .25);
frame.origin.y = CGRectGetMaxY(self.navigationController.navigationBar.frame) - frame.size.height;
self.searchBar.frame = frame;
[self.navigationController.navigationBar.superview insertSubview:self.searchBar belowSubview:self.navigationController.navigationBar];
[UIView animateWithDuration:0.5 animations:^{
CGRect frame = self.searchBar.frame;
frame.origin.y = CGRectGetMaxY(self.navigationController.navigationBar.frame);
self.searchBar.frame = frame;
self.tableView.contentOffset = CGPointMake(0, -250);
}];
}
To be more clear, I'm trying to achieve something similar to the effect seen in the HotelTonight app here (the second screen shows what happens when you hit the top right bar button)
This is I think the best approach for that, use these delegates:
(CGFloat) tableView:(UITableView *)tableView
heightForHeaderInSection:(NSInteger)section (UIView *)
tableView:(UITableView *)tableView
viewForHeaderInSection:(NSInteger)section
How:
Create a BOOL isOpen with a default value of NO
When you click the Search Button, implement this:
(void) searchButtonTouch:(id)sender {
isOpen = (isOpen) ? YES : NO;
isOpen = !isOpen;
[self.urTableView reloadData];
}
Now in your delegates:
(CGFloat) tableView:(UITableView *)tableView heightForHeaderInSection:(NSInteger)section {
return (isOpen) ? 170.0f : 0.0f;
}
(UIView *) tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section {
CGFloat height = [self tableView:tableView heightForHeaderInSection:section];
UIView *vw = [[UIView alloc] initWithFrame:CGRectMake(0, 0, tableView.frame.size.width, height)];
vw.backgroundColor = [UIColor yellowColor];
// add other controls here in your UIView
// or
// just add a UIView at top of your UITableView
// then add other controls to it (if ur using storyboard)
return vw;
}
Add Tapgesture on superview
In TapGesture Action check in if is searchBar view visible
If Visible hide DropDown view by setting new frame with height zero
You can Add Tap Gesture Programmatically or from Interface Builder , You can use its delegate method "shouldReceiveTouch" or any other custom action.

I am having trouble while adding Views to my iCarousel "viewForItemAtIndex" method
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UIView *sub = nil;
//iCarousel *temp;
//create new view if no view is available for recycling
if (view == nil)
{
UIViewController * viewController = [self.storyboard instantiateViewControllerWithIdentifier:#"UIidentifier"];
view = [viewController.view viewWithTag:20];
CGRect Frame = CGRectMake(view.frame.origin.x, view.frame.origin.y + 100, view.frame.size.width, view.frame.size.height);
view.frame = Frame;
}
UILabel *label=(UILabel*)[view viewWithTag:23];
label.text = [[listOfAnimalsNames objectAtIndex:index]nameOfTheCompanie];
return view;
}
I want to display a UIView "mockUp" and fill the labels with some data by using the "index" of the iCarousel, I have created my own UIViewController that contains the "mockup" UIView. The thing is that when I call this UIView (as in the code) nothing happens. (I use the reloadData method after loading data)
Why does each view need its own ViewController? They should all be controlled by whatever is controlling the iCarousel view (or at least its data source). Also, the UILabel should be instantiated only once.
- (UIView *)carousel:(iCarousel *)carousel viewForItemAtIndex:(NSUInteger)index reusingView:(UIView *)view
{
UIView *sub = nil;
if (view == nil)
{
view = [UIView alloc] initWithFrame:CGRectMake(...);
UILabel *label=[[UILabel alloc] initWithFrame:(...)];
[view addSubview:label];
}
label.text = [[listOfAnimalsNames objectAtIndex:index]nameOfTheCompanie];
return view;
}
I want to make a screen with like the video I attach.
I want to scroll until a part of the screen, then, that part sticks in the top and I can go on scrolling.

For Name and Image create customview.
yourTable.tableHeaderView = yourCustomView_Name_image;
For message,call,contact Create customview with 4 UIButtons
- (UIView *)tableView:(UITableView *)tableView viewForHeaderInSection:(NSInteger)section
{
if(section == 0)//do this if you have multiple section.
return youroutletforcustomview_message_call_contact;
return nil;
}
Maybe this will help you . :)
One possible solution using hard-coded values for a contrived example:
In your view controller create two properties:
#property (nonatomic, strong) UIView *stickyHeader;
#property (nonatomic, assign) CGFloat stickyHeaderYPos;
in viewDidLoad:
self.stickyHeader = [[UIView alloc] initWithFrame:CGRectMake(0, 100.0, 320.0, 100.0)];
self.stickyHeader.backgroundColor = [UIColor blueColor];
[self.scrollView addSubview:self.stickyHeader];
self.stickyHeaderYPos = self.stickyHeader.frame.origin.y;
// Allow us to scroll to test
self.scrollView.contentSize = CGSizeMake(320.0, 2000.0);
Set the view controller as the UIScrollView's delegate, and implement scrollViewDidScroll
- (void)scrollViewDidScroll:(UIScrollView *)scrollView {
if (scrollView.contentOffset.y > self.stickyHeaderYPos) {
CGRect frame = self.stickyHeader.frame;
frame.origin.y = scrollView.contentOffset.y;
self.stickyHeader.frame = frame;
}
}
Make the thing which should stick to the top a table view section header.
I would like to create an app that has a function like iOS 7's Notes application. Basically there is one row on the top that has date and time.
My solution is to put the UITextView inside UITableView. First row is UILabel with date and time, the second row is UITextView.
I change both UITextView and UITableViewCell height according to UITextView ContentSize.
The problem is the UITextView size is large so it doesn't automatically scroll when the user hit return key.
Is there any solution to make it scroll as normal?
UITextView is a subclass of UIScrollView. I will suggest an alternative method of implementing a similar functionality. Add the label view as a subview of the text view, and set a contentInset top value of the height of the label.
UILabel* label = [UILabel new];
label.text = #"Test";
[label sizeToFit];
CGRect frame = label.frame;
frame.origin.y -= frame.size.height;
[label setFrame:frame];
[self.textView addSubview:label];
[self.textView setContentInset:UIEdgeInsetsMake(label.frame.size.height, 0, 0, 0)];
Sample project:
http://sdrv.ms/16JUlVD
Try this solution. Fix is based on inheritance. But logic can be used at any place after UITextView text was changed. I have taken some useful code blocks from here:
http://craigipedia.blogspot.ru/2013/09/last-lines-of-uitextview-may-scroll.html
and edited by me for my solution.
Should work.
#interface CustomTextView : UITextView
#end
#implementation CustomTextView
-(id)init {
self = [super init];
if (self) {
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(textDidChange:) name:UITextViewTextDidChangeNotification object:self];
}
return self;
}
-(void)textDidChange:(NSNotification *)notification {
//iOS 7 UITextView auto scroll fix.
NSRange caretRange = self.selectedRange;
if (caretRange.location == self.text.length) {
CGRect textRect = [self.layoutManager usedRectForTextContainer:self.textContainer];
CGFloat sizeAdjustment = self.font.lineHeight * [UIScreen mainScreen].scale;
if (textRect.size.height >= self.frame.size.height - sizeAdjustment) {
if ([[self.text substringFromIndex:self.text.length - 1] isEqualToString:#"\n"]) {
[UIView animateWithDuration:0.2 animations:^{
[self setContentOffset:CGPointMake(self.contentOffset.x, self.contentOffset.y + sizeAdjustment)];
}];
}
}
}
//end of fix
}
#end
I need to put a UIView (for ads) on top of a UITableView in my iphone app. The problem is that when I scroll the table to the bottom the added UIView is scrolling with the table. What I want is for it to be fixed on the bottom of the screen. Is there a way to do that?
This is the code which I have used to add the UIView to the table:
awView = [AdWhirlView requestAdWhirlViewWithDelegate:self];
awView.autoresizingMask=UIViewAutoresizingFlexibleLeftMargin;
[self.tableView addSubview:awView];
Here is how it worked for me. The Ad stays at the bottom of the view.
In ViewDidLoad, in YourController.m:
awView = [AdWhirlView requestAdWhirlViewWithDelegate:self];
awView.center = CGPointMake(self.view.frame.size.width/2, self.view.frame.size.height-kAdWhirlViewHeight/2);
[self.view addSubview:awView];
Then add this method somewhere in the same .m file:
-(void)scrollViewDidScroll:(UIScrollView *)scrollView {
CGRect newFrame = awView.frame;
newFrame.origin.x = 0;
newFrame.origin.y = self.tableView.contentOffset.y+(self.tableView.frame.size.height-kAdWhirlViewHeight);
awView.frame = newFrame;
}
Don't forget to declare awView.
I appreciate this is an old question. But I've found the answers either with false information in part and unclear snippets. So for what it's still worth, here is how I added a "floating" view to the bottom of my UITableViewController's view. Yes, you can do that, even if the accepted answers says you cannot.
In your -viewDidLoad method, you can create a view which we will name bottomFloatingView. This is also set up as a property.
Be sure to add a content inset to the bottom of your table view, this will avoid hiding any of the table's content with your floating view.
Next, you should use the UIScrollViewDelegate to update the frame of the floating view.
The illusion will be that your view is stuck to the bottom. In reality, this view is moving all the time you are scrolling, and is always being computed to appear at the bottom. Scroll views are very powerful ! And probably are one of the most underrated UIKit classes I think.
So here is my code. Note the property, the content inset on the table view and the -scrollViewDidScroll: delegate method implementation. I created my floating view in my storyboard which is why you can't see that being setup.
Also don't forget you should probably also use KVO to observe changes to the table view's frame. It's possible for that to change over time, the easiest way to test that is by toggling on and off the in call status bar in the simulator.
Last thing, if you're using section header views in your table view, those views will be the top most view in the table view so you'll also want to bring your floating view to the front, do this when you change its frame.
#interface MyTableViewController ()
#property (strong, nonatomic) IBOutlet UIView *bottomFloatingView;
#end
#implementation MyTableViewController
static NSString *const cellIdentifier = #"MyTableViewCell";
- (void)dealloc
{
[self.tableView removeObserver:self forKeyPath:#"frame"];
}
- (void)viewDidLoad
{
[super viewDidLoad];
[self.tableView addSubview:self.bottomFloatingView];
self.tableView.contentInset = UIEdgeInsetsMake(0.0, 0.0, CGRectGetHeight(self.bottomFloatingView.bounds), 0.0);
self.tableView.scrollIndicatorInsets = UIEdgeInsetsMake(0.0, 0.0, CGRectGetHeight(self.bottomFloatingView.bounds), 0.0);
[self.tableView addObserver:self
forKeyPath:#"frame"
options:0
context:NULL];
}
#pragma mark - UITableViewDataSource
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
return 20;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
{
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:cellIdentifier forIndexPath:indexPath];
cell.textLabel.text = [NSString stringWithFormat:#"Row %d", indexPath.row];
return cell;
}
#pragma mark - UIScrollViewDelegate

{
CGRect newFrame = self.bottomFloatingView.frame;
newFrame.origin.x = 0;
newFrame.origin.y = self.tableView.contentOffset.y + CGRectGetHeight(self.tableView.bounds) - CGRectGetHeight(self.bottomFloatingView.bounds);
self.bottomFloatingView.frame = newFrame;
[self.tableView bringSubviewToFront:self.bottomFloatingView];
}
#end
Add your view to the superview of the table view (if possible; UITableViewControllermakes this impossible).
Add your view to the table view and reposition it in the -scrollViewDidScroll:delegate method (UITableViewDelegateis a sub-protocol of UIScrollViewDelegate).
I had a similar problem where I wanted to add a loading indicator on top of my UITableViewController. To solve this, I added my UIView as a subview of the window. That solved the problem. This is how I did it.
-(void)viewDidLoad{
[super viewDidLoad];
//get the app delegate
XYAppDelegate *delegate = [[UIApplication sharedApplication] delegate];
//define the position of the rect based on the screen bounds
CGRect loadingViewRect = CGRectMake(self.view.bounds.size.width/2, self.view.bounds.size.height/2, 50, 50);
//create the custom view. The custom view is a property of the VIewController
self.loadingView = [[XYLoadingView alloc] initWithFrame:loadingViewRect];
//use the delegate's window object to add the custom view on top of the view controller
[delegate.window addSubview: loadingView];
}
For people like me looking for a simple solution using Swift, these answers are kind of outdated. Here's what I did (assuming myCustomView was established somewhere else in the file):
func scrollViewDidScroll(_ scrollView: UIScrollView) {
let pixelsFromBottom = CGFloat(20)//or whatever the
let theHeight = self.tableView.frame.height + scrollView.contentOffset.y
myCustomView.frame = CGRect(x: 0, y: theHeight - pixelsFromBottom , width: self.view.frame.width, height: myCustomView.frame.height)
}
- (void)viewDidLoad
{
[super viewDidLoad];
footerView = [[UIView alloc] initWithFrame:CGRectMake(0, SCREEN_HEIGHT-64, SCREEN_WIDTH, 64)];
footerView.backgroundColor = [UIColor blueColor ];
[self.navigationController.view addSubview:footerView];
}
- (void)dealloc
{
[footerView removeFromSuperview];
}
