I am adding the one UIButton in bottom of view -
CGRect frame = [UIScreen mainScreen].applicationFrame;
UIButton *menu_btn = [[UIButton alloc] initWithFrame:CGRectMake(xOffset, frame.size.height - 55, 55, 55)];
[self.view addSubview:menu_btn];
And in the view i have UITableview and i am hiding the uinavigation bar when scrolling down in the list and showing when scrolling up.
menu_btn is moving up and down with the list, I want to fix this button.
Anyone please suggest me,how i can achieve this ?
I added in navigationController.view and its working fine. Thanks guys.
CGRect frame = [UIScreen mainScreen].applicationFrame;
UIButton *menu_btn = [[UIButton alloc] initWithFrame:CGRectMake(xOffset, frame.size.height - 55, 55, 55)];
[self.navigationController.view addSubview:menu_btn];

I'm trying to add UISearchBar (fixed position!) on top of the UITableView.
CGRect rect = self.headerView.frame;
CGRect newRect = CGRectMake(0,
rect.origin.y + rect.size.height,
rect.size.width,
CZP_SEARCHBAR_HEIGHT);
UIView *view = [[UIView alloc] initWithFrame:newRect];
view.backgroundColor = [UIColor whiteColor];
Result (i got a white rect on position where i want my bar):
But if i want to add subview to my view, searchbar appear on 1st cell of tableview (below my view!)
[view addSubview:searchBar];
Here's one way to do it. It looks like you're trying to do it in code instead of a storyboard, so this is a code example. It also looks like you're doing it in a popover of sorts, I put together a quick project as an example that uses a popover, it doesn't look exactly like yours, but it's close enough to get you where you're trying to go I think.
First, here's the code sample, this is from the view controller that contains the header, search bar and tableview.
- (void)viewDidLoad
{
[super viewDidLoad];
// get the desired size for this popover and setup our header height
CGSize viewSize = self.preferredContentSize; // could also be self.view.bounds.size depending on where you're using it
CGFloat headerHeight = 44.0;
// setup our desired frames
CGRect headerFrame = CGRectMake(0, 0, viewSize.width, headerHeight);
CGRect searchContainerFrame = CGRectMake(0, headerHeight, viewSize.width, headerHeight);
// for this frame I'm simply centering it, there's better ways to do it but this is an example
CGRect searchBarFrame = CGRectMake(5, 5, searchContainerFrame.size.width - 10, searchContainerFrame.size.height - 10);
// set our tableview frame to be positioned below our header and search container frame
CGRect tableviewFrame = CGRectMake(0, headerHeight *2, viewSize.width, viewSize.height - (headerHeight * 2));
// create our header view and set it's background color
UIView *headerView = [[UIView alloc] initWithFrame:headerFrame];
headerView.backgroundColor = [UIColor orangeColor];
// create our container view to hold the search bar (not needed really, but if you want it contained in a view here's how)
UIView *searchContainer = [[UIView alloc] initWithFrame:searchContainerFrame];
searchContainer.backgroundColor = [UIColor greenColor];
// instantiate our search bar
UISearchBar *searchBar = [[UISearchBar alloc] initWithFrame:searchBarFrame];
// add the search bar to the container view
[searchContainer addSubview:searchBar];
// create our tableview and position it below our header and search containers
UITableView *tableview = [[UITableView alloc] initWithFrame:tableviewFrame];
tableview.backgroundColor = [UIColor blueColor];
[self.view addSubview:headerView];
[self.view addSubview:searchContainer];
[self.view addSubview:tableview];
}
That snippet gives me a popover with an orange header, a green/grey search bar and a tableview beneath it.
EDIT: If you're interested in looking through the project file that I used to put this together you can download it off github here
I am using the following code to create my scrollview. I would like to move the scrollView down 44px to make room for my nav bar.
scroll = [[UIScrollView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
scroll.backgroundColor = [UIColor clearColor];
scroll.delegate = self;
image = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"Menu.png"]];
scroll.contentSize = image.frame.size;
[scroll addSubview:image];
scroll.minimumZoomScale = scroll.frame.size.width / image.frame.size.width;
scroll.maximumZoomScale = 2.0;
[scroll setZoomScale:scroll.minimumZoomScale];
UITapGestureRecognizer *doubleTap = [[UITapGestureRecognizer alloc] initWithTarget:self action:#selector(handleDoubleTap:)];
[doubleTap setNumberOfTapsRequired:2];
[scroll addGestureRecognizer:doubleTap];
self.view = scroll;
any help is appreciated.
Your code is correct, to manually create a frame do:
scroll = [[UIScrollView alloc] initWithFrame:CGRectMake(0,44,320,480)];
:)
This is for iPod and iphone View but this will let the scroll start at 44px
Cant you just add a scroll view in in interface builder as an outlet, place it underneath your nav bar.
Declare scroll view in .h
in .m under ViewDidLoad
[scroll setScrollEnabled:YES];
[scroll setContentSize: CGSizeMake(320, 1000)]; ////or whatever size you want here
You probably want to init it with a different frame... but it depends on where/how this nav bar is being created. If you have a view controller, and these are all subviews of the view controller's view, then you should be creating the objects in viewDidLoad, then just create the nav bar first, using self.view.bounds to obtain the initialization width. I assume you'll want to put UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleBottomMargin as the autoResizingMask here. Then if the scrollview is the rest of the view below the nav bar, you can create the frame for it using
CGRect scrollFrame = CGRectInset(self.view.bounds, 0, navbar.bounds.size.height)
Put an autoresizingMask of UIViewAutoresizingFlexibleWidth | UIViewAutoResizingFlexibleHeight on the scrollview.
If you are creating the views in a different place/way, then some of that might need modification. I was assuming your view is a nav bar at the top, x pixels tall (44 in this case but it doesn't and shouldn't matter in the context of setting the scrollview frame). and then a scrollview that fills the rest of the view.
Below is the code snippet I am using to set up my UISegment Control
//Add UIView below the nav bar
UIView *buttonContainer = [[UIView alloc]initWithFrame:CGRectMake(0, 0, 320, 30)];
[self.view addSubview:buttonContainer];
//Set up segment control
NSString *nicknameLabel = [NSString stringWithFormat:#"%#",self.nickname];
UISegmentedControl *tempSegmentControl = [[UISegmentedControl alloc]initWithItems:[NSArray arrayWithObjects:nicknameLabel,#"Friends", #"Everyone", nil]];
tempSegmentControl.frame = CGRectMake(-8, 44, 336, 30);
self.segmentControl = tempSegmentControl;
[self.segmentControl setWidth:112 forSegmentAtIndex:0];
[self.segmentControl setWidth:112 forSegmentAtIndex:1];
[self.segmentControl setWidth:112 forSegmentAtIndex:2];
self.segmentControl.selectedSegmentIndex = 0;
[self.segmentControl addTarget:self action:#selector(toggleControls:) forControlEvents:UIControlEventValueChanged];
[self.segmentControl setSegmentedControlStyle:UISegmentedControlStylePlain];
[self changeSegmentFontSize];
[tempSegmentControl release];
[buttonContainer addSubview:self.segmentControl];
[self.view bringSubviewToFront:buttonContainer];
[buttonContainer bringSubviewToFront:self.segmentControl];
[buttonContainer release];
However, I in the app, I am unable to switch between the segments for the segmented control. (only show default first segment highlighted)
Any advice on how I can fix this?
It looks like a bounds problem. The containing view has bounds {0, 0, 320, 30} while the segmented control has {-8, 44, 336, 30}. This means the segmented control is technically "outside" its containing view and the iOS hit test will not register a touch.
Try not setting the segmented control's frame (temporarily comment out the tempSegmentControl.frame = CGRectMake(-8, 44, 336, 30); line) and see what happens.
Check that userInteractionEnabled is set to TRUE for your view, buttonContainer, and segment control.
Check that the bounds of the buttonContainer's superview are wide and tall enough to fully contain the buttonContainer. If they're not then hit-testing wont work and the segmented control wont get any touches.
Is there a way to add some subviews to a view and then be able to position that view so all the subviews will "follow". Acting as a container so to speak for the subviews so I only need to reposition the view and not having to reposition all the subviews in that view.
I'm looking for a solution to do this programtically, not in IB.
If you use a UIView as a parent view all subviews will follow.
UIView *parentView = [[UIView alloc] initWithFrame:self.view.bounds]
[self.view addSubview:parentView]; // Assuming self is a ViewController
UIButton *btn1 = [UIButton buttonWithType:UIButtonTypeRoundedRect];
btn1.frame = CGRectMake(10, 10, 120, 44);
[parentView addSubview:btn1];
// Sets a new position with the same view size
parentView.frame = CGRectMake(50, 100, self.view.bounds.size.width, self.view.bounds.size.height);
Now when you set the new frame of the parentView. The btn1 will have it's position relative to the parentView.
I Hope I understood your question correctly.

I am adding a custom UIImageView to my UINavigationBar using this code:
UIImageView *background = [[[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 320, 44)] autorelease];
[background setImage:[UIImage imageNamed:#"nav_background.png"]];
[background setTag:kTagForReference];
[self.navigationController.navigationBar insertSubview:background atIndex:0];
I then add a custom title using this code:
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 400, 44)];
...
[self.navigationItem setTitleView:label];
[label release];
But on some of my pushed views the title is being hidden (or isn't visible). I can't seem to push more than two views onto the stack without the title disappearing.
I've tried to force my UIImageView background to the back of the bar but that still doesn't help. I've printed the subviews of the UINavigationBar and I can see that the UILabel is there, I just can't see it!
Any help would be greatly appreciated.
If you can run the dumpWindows() function, the output would show the view hierarchy so you can see what view is covering it up.
You most likely want to use a UIToolBar instead of a NavigationBar. Then you can add the subviews to the UIToolbar.
Bring the UILabel to the front most view.
[self.view bringSubviewToFront: label];
