So I have a tableview inside a UIPopOverController and I attached a UISearchBar to the header of the tableview and I have the UISearchDisplayController displaying the correct results. However, I can't get the results to display within the UIPopoverController window. It's displaying behind the popover view into the DetailView covering half the screen (SplitViewController for iPad). How do I bring the results/tableview into the popover view? I tried adding the searchTableView to the popover view, but it just covers up the original tableview.
Here is the code of setting this up:
//Initialize Popover Controller
UIView *ccPopoverView = [[UIView alloc] init];
UIViewController* popoverTableContent = [[UIViewController alloc] init];
self.ccTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 44, 320, 400) style:UITableViewStylePlain];
self.ccTableView.dataSource = self;
self.ccTableView.delegate = self;
self.searchBar = [[UISearchBar alloc] initWithFrame:CGRectMake(0, 0, 320.0, 44.0)];
self.searchDisplayController = [[UISearchDisplayController alloc]initWithSearchBar:self.searchBar contentsController:self];
self.searchDisplayController.searchResultsDataSource = self;
self.searchDisplayController.searchResultsDelegate = self;
self.searchDisplayController.delegate = self;
searchBar.frame = CGRectMake(0, 0, 0, 38);
self.ccTableView.tableHeaderView = searchBar;
ccPopoverView.backgroundColor = [UIColor blackColor];
//Here is where I tried adding the searchResultsTableView as a subview.
//[ccPopoverView addSubview:self.searchDisplayController.searchResultsTableView];
[ccPopoverView addSubview:self.ccTableView];
popoverTableContent.view = ccPopoverView;
self.popoverTableController.delegate = self;
self.popoverTableController = [[UIPopoverController alloc] initWithContentViewController:popoverTableContent];
[self.popoverTableController setPopoverContentSize:CGSizeMake(320, 440) animated:NO];
Thanks!
I fixed the issue instead of adding self when I initialized the search bar, I needed to put in the popovercontroller as the initialization.

I have important problem with UIScrollView.
I want to make one app like yahoo weather and using this source code : BTGlassScrollView
in this source code exist one view with name "foregroundView" that is info view. this info view appear when scrolling my ScrollView from bottom to top.
now I make and add my ScrollView by this code:
_viewScroller = [[UIScrollView alloc] initWithFrame:CGRectMake(0, 0, self.view.frame.size.width + 2*blackSideBarWidth, self.view.frame.size.height)];
[_viewScroller setPagingEnabled:YES];
[_viewScroller setDelegate:self];
[_viewScroller setShowsHorizontalScrollIndicator:NO];
[self.view addSubview:_viewScroller];
_glassScrollView1 = [[BTGlassScrollView alloc] initWithFrame:self.view.frame BackgroundImage:[UIImage imageNamed:#"background3"] blurredImage:nil viewDistanceFromBottom:0 foregroundView:[self customView]];
[_viewScroller addSubview:_glassScrollView1];
in my code I write [self customView] that make me info view and this is customView function:
- (UIView *)customView {
//this method is for make UITableView
[self makeTableBuy:[[self.tableDic objectForKey:#"person"] count]];
UIView *view = [[UIView alloc] initWithFrame:CGRectMake(0, 0, _tableBuy.frame.size.width, _tableBuy.frame.size.height)];
view.layer.cornerRadius = 3;
view.backgroundColor = [UIColor colorWithWhite:0 alpha:.3];
[view addSubview:_tableBuy];
return view;
}
- (UITableView*)makeTableBuy:(int)numberOfRow {
_tableBuy = [[UITableView alloc] initWithFrame:CGRectMake(0,0,self.view.frame.size.width,numberOfRow*TABLE_HEIGHT) style:UITableViewStyleGrouped];
[_tableBuy setTag:1];
[_tableBuy setBackgroundColor:[UIColor clearColor]];
_tableBuy.showsVerticalScrollIndicator = NO;
_tableBuy.separatorStyle = UITableViewCellSeparatorStyleNone;
_tableBuy.rowHeight = TABLE_HEIGHT;
_tableBuy.scrollEnabled = NO;
_tableBuy.delegate = self;
_tableBuy.dataSource = self;
return _tableBuy;
}
now When I'm scrolling my ScrollView my info view (my tableview) moving to top and appear but my scrolling have so lagging.
please guide me how to fix this lag???
I have two views in my program. One is statusView, it's alpha is set to 0.8f. And below it is tableView. How do I disable statusView such way, that clicking on it would not click tableView. Settings userInteractionEnabled = false; didn't help.
Here is how i add views.
[self.view addSubview:_builded.view]; // obj with my tableView
info = [[Info alloc] init];
[self.view addSubview:info.view]; // statusView
If you add a subview like the following, the tableView underneath would not catch the user interaction.
UITableView *testTableView = [[UITableView alloc] initWithFrame:CGRectMake(0, 0, 320, 460)];
testTableView.delegate = self;
testTableView.dataSource = self;
[self.view addSubview:testTableView];
UIView *statusView = [[UIView alloc] initWithFrame:CGRectMake(20, 20, 200, 200)];
statusView.backgroundColor = [UIColor redColor];
statusView.alpha = 0.8;
[self.view addSubview:statusView];
In this code example, i am trying to produce the following view hierarchy
Window -> background image -> scroll view -> text view
All i see however is
Window -> background image
What am i missing please?
-(void) viewWillAppear:(BOOL)animated {
UIScrollView *scrollWindow = [[UIScrollView alloc]
initWithFrame:CGRectMake(30, 30, 440, 212)];
UITextView *scrollableText = [[UITextView alloc] init];
[scrollableText setEditable:NO];
[scrollableText setText:#"Why, hello there"];
[scrollWindow addSubview:scrollableText];
UIImage *backgroundImage = [[UIImage alloc] initWithCGImage:
[UIImage imageNamed:#"about_bg.png"].CGImage];
UIImageView *backgroundView = [[UIImageView alloc]
initWithImage:backgroundImage];
[backgroundView addSubview:scrollWindow];
[[self view] addSubview:backgroundView];
}
Andrew is right about not making the scroll view a subview of the background UIImageView view. But the scroll view is invisible. Only its content (scrollableText) will show. And you haven't set scrollableText's frame, so it's effectively invisible too. Init like so:
[scrollableText setEditable:NO];
[scrollableText setText:#"Why, hello there"];
[scrollableText setFrame:CGRectMake(0, 0, 100, 100)];
And you should see it.
What you need is this hierarchy:
Window
background image view
scroll view
text view
Try adding two subviews to your window, not shove them all as subviews into each other.''-
- (void) viewWillAppear:(BOOL)animated {
UIScrollView *scrollWindow = [[UIScrollView alloc] initWithFrame:CGRectMake(30, 30, 440, 212)];
UITextView *scrollableText = [[UITextView alloc] init];
UIImageView *backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"about_bg.png"]];
scrollableText.editable = NO;
scrollableText.text = #"Why, hello there";
[scrollWindow addSubview:scrollableText];
[self.view addSubview:backgroundView];
[self.view addSubview:scrollWindow];
}
I create a UIViewController (a custom calendar and its size is 550x440) and when i push a button it must be appear; the problem is that if I use setModalPresentationStyle and setModalTransitionStyle they change size of my view; can I set the size for these presentation?
I find a solution:
[self presentModalViewController:calendar animated:YES];
calendar.view.superview.frame = CGRectMake(0, 0, 200, 200);
Maybe you want to change your design to implement your calendar as a popover:
// Define the size of the calendar view controller for the popover
UIViewController *viewController = [[UIViewController alloc] init];
viewController.contentSizeForViewInPopover = CGSizeMake(550.0f, 440.0f);
viewController.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:viewController];
navigationController.navigationBar.barStyle = UIBarStyleBlackOpaque;
// Create the popover
UIPopoverController *popoverController = [[UIPopoverController alloc] initWithContentViewController:navigationController];
// Present the popover from one button
[popoverController presentPopoverFromBarButtonItem:button permittedArrowDirections:UIPopoverArrowDirectionDown animated:YES];
//release the popover content
[viewController release];
[navigationController release];
I have a very tricky problem and after long searching (google, stackoverflow, ...) i didn't get the solution that works for me.
Let me introduce you in my current choosen architecture:
I have a a AppDelegate, which has a UIView that contains a UINavigationController and the application didFinishLaunchingWithOptions: contains:
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 400)];
UIViewController *myController = [[UIViewController alloc] init];
myController.view = myView;
FSCScrumRootView * myRootView = [[FSCScrumRootView alloc] initWithNibName:#"FSCScrumRootView" bundle:[NSBundle mainBundle]];
[myController.view addSubview:myRootView.navigation.view];
[self.window addSubview:myController.view];
[self.window makeKeyAndVisible];
return YES;
}
In my FSCScrumRootView (inherits from UIViewController) i init the view like this:
- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
if (self) {
// Custom initialization
self.navigation = [[[UINavigationController alloc] init] autorelease];
self.scrumProjectsList = [[[FSCScrumProjectListView alloc] init] initWithNibName:#"FSCScrumProjectListView" bundle:nil];
[navigation pushViewController:scrumProjectsList animated:YES];
[navigation view];
}
return self;
}
In my FSCScrumProjectListView (it is inherited from UITableViewController) i have implemented the viewDidLoad as following:
- (void)viewDidLoad
{
[super viewDidLoad];
//Set the title
self.navigationItem.title = #"Scrum Projects";
UIBarButtonItem *myRefreshButton = [[[UIBarButtonItem alloc] initWithTitle:#"Refresh" style:UIBarButtonSystemItemRefresh target:self action:#selector(refreshList)] autorelease];
self.navigationItem.leftBarButtonItem = myRefreshButton;
UIBarButtonItem *myLogoutButton = [[UIBarButtonItem alloc] initWithTitle:#"Logout" style:UIBarButtonSystemItemCancel target:self action:#selector(logout)];
self.navigationItem.rightBarButtonItem = myLogoutButton;
//Initialize the toolbar
toolbar = [[UIToolbar alloc] init];
toolbar.barStyle = UIBarStyleDefault;
//Set the toolbar to fit the width of the app.
[toolbar sizeToFit];
//Caclulate the height of the toolbar
CGFloat toolbarHeight = [toolbar frame].size.height;
//Get the bounds of the parent view
CGRect rootViewBounds = self.parentViewController.view.bounds;
//Get the height of the parent view.
CGFloat rootViewHeight = CGRectGetHeight(rootViewBounds);
//Get the width of the parent view,
CGFloat rootViewWidth = CGRectGetWidth(rootViewBounds);
//Create a rectangle for the toolbar
CGRect rectArea = CGRectMake(0, rootViewHeight - toolbarHeight, rootViewWidth, toolbarHeight);
//Reposition and resize the receiver
[toolbar setFrame:rectArea];
//Create a button
UIBarButtonItem *infoButton = [[UIBarButtonItem alloc]
initWithTitle:#"Info" style:UIBarButtonItemStyleBordered target:self action:#selector(info_clicked:)];
[toolbar setItems:[NSArray arrayWithObjects:infoButton,nil]];
//Add the toolbar as a subview to the navigation controller.
[self.navigationController.view addSubview:toolbar];
//Reload the table view
[self.tableView reloadData];
}
This results finally in the following screen (as i'd like to have it):
View iOS Mockup of current result
The Problem:
My Problem now is, that i can click ONLY on the Refresh Button. The other two buttons (Info and Logout) cannot be clicked. And i don't understand why? What I am doing wrong here?
Your help is kindly appreceated!
Try autoreleasing the second two buttons like your first one (the refresh).
UIBarButtonItem *myLogoutButton = [[[UIBarButtonItem alloc] initWithTitle:#"Logout" style:UIBarButtonSystemItemCancel target:self action:#selector(logout)]autorelease];
UIBarButtonItem *infoButton = [[[UIBarButtonItem alloc]
initWithTitle:#"Info" style:UIBarButtonItemStyleBordered target:self action:#selector(info_clicked:)]autorelease];
People, i have found the reason for my problem and i have to say, it was a very very silly one.
The first line of this project was responsible for all the troubels:
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 200, 400)];
Since the View i created there is only sized 200x400, it is to small to recognize any events that appear in the outside of this view (although everything is visible).
If i change the size of this view, all works as expected:
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, 300, 500)];
But the more dynamic solution would probably be:
CGRect cgRect =[[UIScreen mainScreen] bounds];
CGSize cgSize = cgRect.size;
UIView *myView = [[UIView alloc] initWithFrame:CGRectMake(0, 0, cgSize.width, cgSize.height)];
Maybe there is an even better solution for getting the dynamic screen size?
