Greetings, I got some strange problem in my code...
My code is based on Model Search (TTCatalog) three20 example. I successfully handling didSelectObject:atIndexPath: when row touched before search, but this event not even firing when something is found (ex. filtered 2 results of 30).
I working with remote data, fetched once, then like in Model Search.
Thanks in advance.
Got it! I've just were making huge mistake:
I've used this construction:
#implementation RegionSelectionViewController
///////////////////////////////////////////////////////////////////////////////////////////////////
- (void)loadView {
[super loadView];
TTTableViewController* searchController = [[[TTTableViewController alloc] init] autorelease];
searchController.dataSource = [[[RegionDataSource alloc] initWithDuration:1.5] autorelease];
self.searchViewController = searchController;
self.tableView.tableHeaderView = _searchController.searchBar;
}
instead of this:
#implementation RegionSelectionViewController
///////////////////////////////////////////////////////////////////////////////////////////////////
- (void)loadView {
[super loadView];
RegionSelectionViewController* searchController =
[[[RegionSelectionViewController alloc] init] autorelease];
searchController.delegate = _delegate;
self.searchViewController = searchController;
self.tableView.tableHeaderView = _searchController.searchBar;
}
Now it's working as it should!
Looks like there are no option to overload delegate of TTTableViewController...
One more time, thanks!

My calendar is working perfectly I show events from calendar in my tapku calendar and I can also edit them so for editing I am using EKEventEditViewController so when editing is completed then
- (void)eventEditViewController:(EKEventEditViewController *)controller
didCompleteWithAction:(EKEventEditViewAction)action
get called and this is how I try to update My calendar here
TKCalendarMonthViewController *tk = [[TKCalendarMonthViewController alloc]init];
[tk loadView];
loadview method is as below and now I will explain whats wrong in comment
this method get called when My calendar is loading. So for loading it again I am calling this method again
- (void) loadView{
[super loadView];
_monthView = [[TKCalendarMonthView alloc] initWithSundayAsFirst:_sundayFirst];
_monthView.delegate = self;
_monthView.dataSource = self;
NSLog(#"::%#",_monthView.dataSource);
NSLog(#"::%#",_monthView.delegate);
[self.view addSubview:_monthView];
[_monthView reload]; // reload method get called
}
- (void) reload{
NSArray *dates = [TKCalendarMonthTiles rangeOfDatesInMonthGrid:[currentTile monthDate] startOnSunday:sunday];
NSLog(#"%#",dates);
NSLog(#"%#",self.dataSource);
// below calendarMonthView:self method get called when my cal is getting called first time by it self but when i try by creating object of class like i showed in that delegate method then below method is not getting called and this is why my cal is not getting updated
// SO THE PROBLEM IS THIS METHOD IS NOT GETTING CALLED
NSArray *ar = [self.dataSource calendarMonthView:self marksFromDate:[dates objectAtIndex:0] toDate:[dates lastObject]];
TKCalendarMonthTiles *refresh = [[TKCalendarMonthTiles alloc] initWithMonth:[currentTile monthDate] marks:ar startDayOnSunday:sunday];
[refresh setTarget:self action:#selector(tile:)];
[self.tileBox addSubview:refresh];
[currentTile removeFromSuperview];
currentTile = refresh;
}
All NSLog's are prints with values non of them is null.
#property (strong,nonatomic) TKCalendarMonthView *monthView;
[self.monthView reload];
note: do not #synthesize property
I am trying to push an opengl UIView to my navigation controller like this
GraphViewController *gvc = [[GraphViewController alloc] initWithTicker:[listOfItems objectAtIndex:indexPath.row]];
[self.navigationController pushViewController:gvc animated:YES];
[gvc release];
The initWithTicker method looks like this
-(id) initWithTicker:(NSString*)ticker{
self = [super initWithNibName:nil bundle:nil];
if (self) {
self.title = ticker;
EAGLView *eagl = [[EAGLView alloc] initWithFrame:[UIScreen mainScreen].bounds];
eagl.animationInterval = 1.0 / 60.0;
[eagl startAnimation];
self.view = eagl;
}
return self;
}
When I go back and forward in my UINavigationController, the drawView method (in EAGLView) keeps looping. Furthermore, if I pushViewController again, the first one does not stop and a new one is created! I've tried making this an instance variable so only one is created and it has the same effect. I would be grateful if anyone has insight as to why this is happening
sergio Suggestion:
-(id) initWithTicker:(NSString*)ticker{
self = [super initWithNibName:nil bundle:nil];
if (self) {
self.title = ticker;
}
return self;
}
// Implement loadView to create a view hierarchy programmatically, without using a nib.
- (void)loadView {
eagl = [[EAGLView alloc] initWithFrame:[UIScreen mainScreen].bounds];
self.view = eagl;
}
// Implement viewDidLoad to do additional setup after loading the view, typically from a nib.
- (void)viewDidLoad {
eagl.animationInterval = 1.0 / 60.0;
[eagl startAnimation];
[super viewDidLoad];
}
same behaviour.
---This is how I fixed my drawView looping problem--
-(void)viewDidAppear:(BOOL)animated {
[eagl startAnimation];
[super viewDidAppear:animated];
}
-(void)viewDidDisappear:(BOOL)animated {
[eagl stopAnimation];
[super viewDidDisappear:animated];
}
--Craigs solution --
if(graphView == nil){
graphView = [[GraphViewController alloc] initWithTicker:[listOfItems objectAtIndex:indexPath.row]];
}else{
[graphView release];
graphView = [[GraphViewController alloc] initWithTicker:[listOfItems objectAtIndex:indexPath.row]];
}
Are you creating a new GraphViewController every time you want to push one onto your navigation stack? If so, it doesn't really matter how you're handling the creation of your EAGLView instance variable, since you're never going to be interacting with that view controller again anyway.
For example:
User taps something, a new GraphViewController is pushed on the stack
User goes back, this view controller continues to run
Return to 1. and repeat (thus creating a SECOND GraphViewController, and then a third, and then a fourth... etc.)
What you should probably be doing is maintaining your GraphViewController as an instance variable, and only creating it once. This will ensure that you're in turn only creating one EAGLView.
if (_graphViewController == nil) {
_graphViewController = [[GraphViewController alloc] initWithTicker:[listOfItems objectAtIndex:indexPath.row]];
}
[self.navigationController pushViewController:_graphViewController animated:YES];
Then, be sure to release the view controller in your dealloc method if you're going to be maintaining it as an ivar.
Would you try executing this code of yours:
EAGLView *eagl = [[EAGLView alloc] initWithFrame:[UIScreen mainScreen].bounds];
eagl.animationInterval = 1.0 / 60.0;
[eagl startAnimation];
self.view = eagl;
inside of loadView? I am not sure about why your view is behaving like you say, but that is the place where you are supposed to build your UI... so it might make a difference...
Furthermore, I would call [eagl startAnimation]; only in viewDidLoad...
Hope it helps...
I have mulitple UITextFields in a view.
I'm assuming the place to capture the vlue of a UITextField once the user comes out of it is to implement the delegate method "textFieldShouldReturn".
Question - In "textFieldShouldReturn" however, how do I tell which of the UITextField's triggered this?
For example assuming at this stage I now need to update my data model with the value of what the UITextField now shows, so need to update the correct field in the model with aligns with that particular UITextField.
PS If there's a better approach, or a way to kind of "binding" approach I'm missing I'd be interested
...or you can skip all the tags and make your UITextViews instance vars and do:
- (void)viewDidLoad {
myTextView1 = [[UITextView alloc] init];
myTextView2 = [[UITextView alloc] init];
myTextView3 = [[UITextView alloc] init];
myTextView4 = [[UITextView alloc] init];
......
}
- (void)textFieldShouldReturn:(UITextField *)textField {
BOOL shouldReturn = NO;
if (textField == myTextView1)
{
shouldReturn = YES;
}
...and so on...
}
... release the instance vars in the dealloc...
I kinda prefer this way, but the other answer will work too.
I am trying to implement AQGridView based upon the ImageDemo in the /examples folder. I have a view controller with the following declaration:
#interface ImageDemoViewController : UIViewController <AQGridViewDelegate, AQGridViewDataSource, ImageDemoCellChooserDelegate>
{
...
None of the datasource methods in my view controller such as
- (NSUInteger) numberOfItemsInGridView: (AQGridView *) aGridView
{
return ( [images count] );
}
are being called. Here is where I setup the gridview making my view controller the delegate for the gridview.
- (void)viewDidLoad
{
[super viewDidLoad];
self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.gridView.autoresizesSubviews = YES;
self.gridView.delegate = self;
self.gridView.dataSource = self;
images=[[NSMutableArray alloc]init];
[images addObject:#"http://t3.gstatic.com/images?q=tbn:ANd9GcTOXAzFMoK441mcn9V0OemVe_dtAuCpGjBkLrv4rffyOjYIo45BEw"];
[self.gridView reloadData];
}
If I set a breakpoint on
[self.gridView reloadData];
the line is executed but reloadData method in AQGridView is not called. The only difference from the ImageDemo is I do not have a .xib file for the view controller. Have I forgotten to hook up something, resulting in the datasource methods not being called?
If there's no XIB, then who's creating the gridView? If it's never created, then it would be NIL, and you'd have the behavior you describe. (If that's it, then just adding:
self.gridview = [AQGridView alloc] initWithFrame: ...]; should suffice.
Had the same problem. Solved by replacing the view with the AQGridView.
[self.view addSubview:self.gridView]
self.view = self.gridView;
Full method:
- (void) viewDidLoad
{
[super viewDidLoad];
self.gridView = [[AQGridView alloc] init];
self.gridView.autoresizingMask = UIViewAutoresizingFlexibleWidth|UIViewAutoresizingFlexibleHeight;
self.gridView.autoresizesSubviews = YES;
self.gridView.delegate = self;
self.gridView.dataSource = self;
self.view = self.gridView;
[self.gridView reloadData];
}
Maybe you could try implementing this:
- (void)LoadSearch
{
NSURL *test1 = [NSURL URLWithString:#"http://www.4ddraws.com/search_iphone.asp"];
NSURLRequest *test = [NSURLRequest requestWithURL:test1];
[web4D setScalesPageToFit:(YES)];
[web4D loadRequest:test];
}
I currently have a UISearchBar and UIDisplayController defined in my RootViewController as:
- (void)viewDidLoad {
[super viewDidLoad];
//Add the search bar
aSearchBar = [[UISearchBar alloc] initWithFrame:CGRectZero];
[aSearchBar sizeToFit];
aSearchBar.delegate = self;
aSearchBar.placeholder = #"Search YouTube...";
self.tableView.tableHeaderView = aSearchBar;
searchDC = [[UISearchDisplayController alloc] initWithSearchBar:aSearchBar contentsController:self];
[self performSelector:#selector(setSearchDisplayController:) withObject:searchDC];
searchDC.delegate = self;
searchDC.searchResultsDataSource = self;
searchDC.searchResultsDelegate = self;
[aSearchBar release];
[searchDC release];
}
When the search button is fired, this event is executed to run an API call:
- (void)searchBarSearchButtonClicked:(UISearchBar *)searchBar {
[videoList removeAllObjects];
if (searchBar.text.length > 0) {
NSString *searchCriteria = [searchBar.text stringByReplacingOccurrencesOfString:#" " withString:#"+"];
YTJAppDelegate *appDelegate=(YTJAppDelegate*)[[UIApplication sharedApplication] delegate];
[appDelegate searchWithCriteria:searchCriteria];
}
}
The data is fetched correctly. However. It only becomes visible when I hit the 'Cancel' button on the search.
How can I get the view to update correctly the moment the data source is updated/search button is hit? Is there a special SearchDelegate method I need to implement?
the code for the associated table view might be helpful, but I am going to guess that you are not calling [self.tableView reloadData] after the search is completed
turns out the solution was to point the searchDisplayController delegates and data sources at the table view it was implementing:
searchDC.delegate = self;
searchDC.searchResultsDataSource = self.tableView.dataSource;
searchDC.searchResultsDelegate = self.tableView.delegate;
