I want to add a custom UIImageView to UISearchDisplayController's table view background and set table view's background color to clearColor. Tried a few different approach but couldn't find the right solution. Any idea how to approach this?
Note: I don't want to add to searchDisplayController's searchResultsTableView's view hierarchy, but rather overlay another sibling view below it)
You can set the background image in a similar way you would for your main table, only set it in the searchDisplayControllerDidBeginSearch delegate method. For instance:-
- (void)searchDisplayControllerDidBeginSearch:(UISearchDisplayController *)controller {
[controller.searchResultsTableView setDelegate:self];
UIImageView *anImage = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"gradientBackground.png"]];
controller.searchResultsTableView.backgroundView = anImage;
[anImage release];
controller.searchResultsTableView.separatorStyle = UITableViewCellSeparatorStyleNone;
controller.searchResultsTableView.backgroundColor = [UIColor clearColor]; }
You can also do this wherever you instantiate your UISearchDisplayController. In my app I was doing this in my UITableView viewDidLoad method and was matching the styles between the two tables:
- (void)viewDidLoad
{
[super viewDidLoad];
self.tableView.separatorColor = [UIColor blackColor];
self.tableView.backgroundColor = [UIColor grayColor];
self.tableView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320, 44)];
searchController = [[UISearchDisplayController alloc] initWithSearchBar:searchBar contentsController:self];
searchController.delegate = self;
searchController.searchResultsDataSource = self;
searchController.searchResultsDelegate = self;
searchController.searchResultsTableView.separatorColor = self.tableView.separatorColor;
searchController.searchResultsTableView.backgroundColor = self.tableView.backgroundColor;
searchController.searchResultsTableView.indicatorStyle = UIScrollViewIndicatorStyleWhite;
}

I'm trying to add subview in my ViewController using this method
- (void)viewDidLoad
{
[super viewDidLoad];
addCourse = [[UIView alloc]init];
addCourse.backgroundColor = [UIColor redColor];
[addCourse.layer setCornerRadius:50.0f];
[addCourse.layer setMasksToBounds:YES];
}
Where addCourse is my subview but the background color is still white. and I'm using storyboard and added the subview with it and linked the View with viewcontroller and I did write the IBOutlet and the property and synthesize but still I couldn't find a way to change the background color.
How I can change it ?
If you already linked with the ViewController then you just need to remove the below line from your code
addCourse = [[UIView alloc]init];
Because, it create the new instance of your subView.
You haven't added addCourse to your view controller as as I can see. replace your viewDidLoad method with:
- (void)viewDidLoad
{
[super viewDidLoad];
addCourse = [[UIView alloc]init];
addCourse.backgroundColor = [UIColor redColor];
[addCourse.layer setCornerRadius:50.0f];
[addCourse.layer setMasksToBounds:YES];
//ADDED THIS LINE
self.view = addCourse;
}
See I have updated your code (Just you need to Set View's Frame) and I got the Result
Please! Update your code this way
- (void)viewDidLoad
{
[super viewDidLoad];
//custom view
UIView *addCourse = [[UIView alloc]init];
CGRect myViewframe = CGRectMake(10.0f, 90.0f, 100.0f, 100.0f);
addCourse.frame=myViewframe;
addCourse.backgroundColor = [UIColor redColor];
[addCourse.layer setCornerRadius:50.0f];
[addCourse.layer setMasksToBounds:YES];
[self.view addSubview:addCourse];
}
and Here is the result screen
addCourse = [[UIView alloc]initWithFrame:CGRectMake(x, y, w, h)];
addCourse.backgroundColor = [UIColor redColor];
[addCourse.layer setCornerRadius:50.0f];
[addCourse.layer setMasksToBounds:YES];
[self.view addSubview:addCourse];
I'm new to programming, and I know how to add a static image behind a tableView in a .xib file, but not in code. I have tried the following code:
UIImage * image = [UIImage imageNamed:#"pic.png"];
[self.view addSubView: image];
but nothing happens when I write this!
To display an UIImage you have to use an UIImageView and put it under the UITableView using the same frame. Don't forget to set the table view's background to transparent.
UIImageView *iv = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"pic.png"]];
iv.frame = CGRectMake(0.0, 0.0, 300.0, 600.0);
UITableView *tv = [[UITableView alloc] initWithFrame:iv.frame style:UITableViewStylePlain];
tv.opaque = NO;
tv.backgroundColor = [UIColor clearColor];
[self.view addSubView: iv];
[self.view addSubView: tv];
[iv release];
[tv release];
You need to use a UIImageView, not a UIImage. Also, when adding a view programmatically, don't forget to set the frame.
I want to set an image and a label at the center of my UINavigationBar, along all my navigation stack.
What I'm currently doing is adding it to my navigation item titleView.
The "problem" with this approach is that I have to call this method in the viewDidLoad for each view controller I push to my navigation stack.
The other way around is to add the UILable and UIImageView directly to the UINavigationBar, however that why I have to calculate the center myself, and in addition I read that's not the recommended approach.
Any Idea how to get what I want ?
My Code:
CGRect navTitle = controller.navigationController.navigationBar.bounds;
CGFloat aHeight = navTitle.size.height;
UIView* container = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 163, aHeight)];
UIImage* statusImg = [UIUtils getStatusImage];
UIImageView *statusImage = [[UIImageView alloc] initWithFrame:CGRectMake(0,aHeight/2-statusImg.size.height/2, 33., 32.)];
statusImage.autoresizingMask = UIViewAutoresizingNone;
statusImage.image = statusImg;
statusImage.backgroundColor = [UIColor clearColor];
[statusImage setTag:1];
[statusImage setHidden:NO];
initWithFrame:CGRectMake(statusImage.frame.origin.x + 33. + 3, 0, 130., navTitle.size.height)];
UILabel *titleLabel = [[UILabel alloc] initWithFrame:CGRectMake(statusImage.frame.origin.x + 33. + 3, 0, 130., navTitle.size.height)];
titleLabel.textAlignment = UITextAlignmentLeft;
titleLabel.lineBreakMode = UILineBreakModeTailTruncation;
titleLabel.textColor = [UIColor whiteColor];
titleLabel.font = [UIFont boldSystemFontOfSize:20.];
titleLabel.shadowOffset = CGSizeMake(1, -1);
titleLabel.opaque = NO;
titleLabel.backgroundColor = [UIColor clearColor];
[titleLabel setTag:2];
[container addSubview:statusImage];
[container addSubview:titleLabel];
controller.navigationItem.titleView = container;
[statusImage release];
[titleLabel release];
[container release];
Found the a nice way to do it :
Registering yourself as the delegate of UINavigationController will let you receive a callback each time a new controller is about to be pushed.
- (void)navigationController:(UINavigationController *)navigationController willShowViewController:(UIViewController *)viewController animated:(BOOL)animated
Inside that function, getting the viewController and operating on his navigationitem will do the trick.
I am trying to create a view that looks like the following:
I know it's a UISplitView, however my issue is that on creating the UIToolBar that is below the UITableView to the left and also on how to create the icons on top of the detail view (the one with the trash can logo, reply, and new message). How do I do this?
If you look at the DetailView.xib for a UISplitView project in Interface Builder you can drag UIBarButtonItems onto the toolbar contained in it.
To get a toolbar in the popover controller you can just use the toobar that comes with a UINavigationController. The code below should give you an idea of how to do this. Add this code to RootViewController.
- (void)viewDidLoad
{
[super viewDidLoad];
self.clearsSelectionOnViewWillAppear = NO;
self.contentSizeForViewInPopover = CGSizeMake(320.0, 600.0);
//setup toolbar
self.navigationController.toolbarHidden = NO;
UIBarButtonItem *refreshItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemRefresh target:self action:#selector(refresh:)];
[self setToolbarItems:[NSArray arrayWithObjects:refreshItem, nil]];
[refreshItem release];
UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(60.0, 10.0, 200.0, 21.0)];
label.backgroundColor = [UIColor clearColor];
label.textColor = [UIColor whiteColor];
label.text = #"This is a label on the toolbar";
[self.navigationController.toolbar addSubview:label];
[label release];
}
I have a viewController that has a tableView and a custom loading UIView that displays a loading message and spinner while the data of the tableView is being loaded.
The custom UIView has a red background that i can see, but i can still see the lines of the tableView, How can i get to display the custom uiview without seeing the tableView lines on the background.
#implementation LoadingView
#synthesize spinner;
- (id)initWithFrame:(CGRect)frame {
if (self = [super initWithFrame:frame]) {
// Initialization code
[self setUserInteractionEnabled:NO];
[self setBackgroundColor:[UIColor blueColor]];
// Spinner
spinner = [[UIActivityIndicatorView alloc] initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];
[spinner setCenter:CGPointMake(320/2, 150)];
[self addSubview:spinner];
[spinner startAnimating];
//title label
UILabel *titleLabel = [[UILabel alloc] init];
titleLabel.text = #"Loading...";
titleLabel.font = [UIFont boldSystemFontOfSize:18];
titleLabel.lineBreakMode = UILineBreakModeWordWrap;
titleLabel.backgroundColor = [UIColor clearColor];
titleLabel.textColor = [UIColor blackColor];
titleLabel.textAlignment = UITextAlignmentLeft;
CGFloat height = [titleLabel.text sizeWithFont: titleLabel.font constrainedToSize: CGSizeMake(300, 1500) lineBreakMode: UILineBreakModeWordWrap].height;
[titleLabel setFrame: CGRectMake(120, 180, 100, height)];
[self addSubview:titleLabel];
[titleLabel release];
}
return self;
}
- (void)drawRect:(CGRect)rect {
}
- (void)dealloc {
[super dealloc];
[spinner release];
}
#end
You can set the lines "off", when you start you loading process, setting them transparent.
// Setting transparent
tableView.separatorColor = [UIColor clearColor];
And when you remove the loading UIView, you change the color for the one that you want.
// Setting the desired color
tableView.separatorColor = [UIColor grayColor];
Another alternative is to set the table view hidden while you don't have data to be displayed, and than when the first or more row appear you place you set the table view to not hidden.
I hope this will help you!

The problem was that self.view in the viewController had the tableView assigned directly. The solution is to assign the self.view a UIView and add the tableView and the custom UIView on top of self.view.
This is sample code from the viewController.
- (void)loadView {
UIView *aView = [[UIView alloc] initWithFrame:[[UIScreen mainScreen] applicationFrame]];
//tableView
self.tableView = [[[UITableView alloc] initWithFrame:[[UIScreen mainScreen] bounds] style:UITableViewStylePlain] autorelease];
//set the rowHeight once for performance reasons.
//self.tableView.separatorStyle = UITableViewCellSeparatorStyleNone;
self.tableView.rowHeight = 75;
self.tableView.backgroundColor = [UIColor clearColor];
self.tableView.autoresizingMask = (UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight);
self.tableView.delegate = self;
self.tableView.dataSource = self;
self.tableView.autoresizesSubviews = YES;
[aView addSubview:tableView];
//set the rowHeight once for performance reasons.
self.view = aView;
[aView release];
}
- (void)viewDidLoad {
[super viewDidLoad];
loadingView = [[LoadingView alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.view addSubview:loadingView];
//fetch productsArray
[self productListRequestStart];
}
