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 using the Kal calendar in my app, (hopefully that doesn't change too much) but I get an EKEvent object from that depending on the user selection on the calendar.
Anyway, how can I edit and delete an event which already exists? Namely the EKEvent that I receive?
I need to do this all programatically, I am not using any of Apple's pre-made EKEventViewController's.
I can successfully create and save new events, but Im unsure of how to edit or delete existing ones, any help would be appreciated, thanks.
A complete answer would almost require a demo project.
Other approach would be simply giving you a link to Event Kit Programming Guide.
Since you did not provide any code (what you have tried already) i hope this extract from a working app will push you to the right track.
Note that i sublassed EKEventViewController due to app's specifics - this is not neccessary. I had to sublass it simply because original EKEventViewController
didn't spawn with black navigationBar (this was reported as a bug also, don't now if it's
fixed already).
You know how to add an event to calendar, so there's no need to write about getting a reference to EKEventStore and EKCalendar.
You're also not asking about how to retreive an event from calendar so let's assume you already have some kind of mechanism to select (receive) the event and you want to edit it. Let's say it is:
EKEvent *selectedEvent = (EKEvent *)[events objectAtIndex: selectedIndex];
I create this viewController as a property of appDelegate - you probably have better solution. appDelegate also holds eventStore and defaultCalendar reference - your approach could differ.
appDelegate.detailViewController = [[MPEventViewController alloc] initWithNibName:nil bundle:nil];
appDelegate.detailViewController.event = selectedEvent;
appDelegate.detailViewController.eventStore = appDelegate.eventStore;
appDelegate.detailViewController.defaultCalendar = appDelegate.defaultCalendar;
appDelegate.detailViewController.allowsEditing = NO;
[appDelegate.navigationController pushViewController:appDelegate.detailViewController animated:YES];
Sublcassing (again, this is not neccessary but it might come useful) goes like this:
MPEventEditViewController.h
#import <Foundation/Foundation.h>
#import <EventKitUI/EventKitUI.h>
#interface MPEventViewController : EKEventViewController <EKEventEditViewDelegate>
#property (nonatomic, strong) EKEventStore *eventStore;
#property (nonatomic, strong) EKCalendar *defaultCalendar;
- (void)editEvent:(id)sender;
#end
MPEventEditViewController.m
#import "MPEventViewController.h"
#import "----------AppDelegate.h"
#implementation MPEventViewController
#synthesize eventStore;
#synthesize defaultCalendar;
- (void)viewDidLoad {
[super viewDidLoad];
[self setTitle: [self.event title]];
self.allowsEditing = NO;
self.navigationController.navigationBar.barStyle = UIBarStyleBlack;
self.navigationItem.rightBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:
UIBarButtonSystemItemEdit target:self action:#selector(editEvent:)];
//this has nothing to do with the answer :)
//[[self.navigationController navigationBar] setTintColor: [UIColor colorWithHexString: NAVBAR_TINT_COLOR]];
}
- (void)editEvent:(id)sender {
EKEventEditViewController *addController = [[EKEventEditViewController alloc] initWithNibName:nil bundle:nil];
//this has nothing to do with the answer :)
//[addController.navigationBar setTintColor: [UIColor colorWithHexString: NAVBAR_TINT_COLOR]];
addController.eventStore = self.eventStore;
addController.event = self.event;
addController.navigationBar.barStyle = UIBarStyleBlack;
addController.editViewDelegate = self;
[self presentModalViewController:addController animated:YES];
}
- (void)eventEditViewController:(EKEventEditViewController *)controller
didCompleteWithAction:(EKEventEditViewAction)action {
NSError *error = nil;
EKEvent *thisEvent = controller.event;
switch (action) {
case EKEventEditViewActionCanceled:
break;
case EKEventEditViewActionSaved:
[controller.eventStore saveEvent:controller.event span: EKSpanFutureEvents error:&error];
break;
case EKEventEditViewActionDeleted:
[controller.eventStore removeEvent:thisEvent span: EKSpanFutureEvents error:&error];
break;
default:
break;
}
//here would be the place to reload data if you hold it in some kind of UITableView
[controller dismissModalViewControllerAnimated:YES];
}
- (EKCalendar *)eventEditViewControllerDefaultCalendarForNewEvents:(EKEventEditViewController *)controller {
EKCalendar *calendarForEdit = self.defaultCalendar;
return calendarForEdit;
}
- (void)dealloc {
eventStore = nil;
defaultCalendar = nil;
}
#end
Only after writing all this i remembered there is a great sample code SimpleEKDemo. In fact some of this posted code is probably originates from there.
EDIT:
After the question was edited the above answer became off-topic.
In that case you should take a look at EKCalendarItem and EKevent.
You can change allmost all properties programatically (most of them are inherited from EKCalendarItem).
Maybe you were distracted for example becaues hasNotes is readonly. That is because hasNotes is kind of a function and not a real property. Properties like notes, atendees, startDate, endDate etc. are perfectly editable.
For saving modified event you can still use:
NSError error = nil;
[self.eventStore saveEvent:event span: EKSpanFutureEvents error:&error];
And for deleting it:
NSError error = nil;
[self.eventStore removeEvent:event span: EKSpanFutureEvents error:&error];
EDIT2: for deleting all events try this:
//assuming self.eventStore is already properly set in code
//identifierArray would be your NSMutableArray holding event identifiers
//change the name according to your code
NSError error = nil;
for (NSString *eventIdentifier in removeAllObjects) {
EKEvent *event = [self.eventStore eventWithIdentifier:eventIdentifier];
[self.eventStore removeEvent:event span:EKSpanFutureEvents error:&error];
}
//now you can also clear identifiers
[removeAllObjects removeAllObjects];
Note: there's no guarantee you'll be able to delete all events - only events from
default calendar which is set by usert in settings app.
I am creating a split-view iPad application. When the user presses the bar button item in the master view, a modal is presented. This modal has a textfield and has an IBAction to pick up keyboard returns.
On keyboard returns, a new instance of my Farm class is created (code below). This instance is then added to an array that is stored in my delegate. I then try to reload the MasterViewController's table. Upon this reload the application crashes on cell.textLabel.text with a EXC_BAD_ACCESS error.
Farm *current = [delegate.arrayOfFarms objectAtIndex:indexPath.row];
cell.textLabel.text = [current getFarmTitle];
If I ask the array within the delegate how many elements it has, it will indeed show the current amount, even. This is what is bizarre to me about this whole thing: the Farm instances appear to be in existence.
I have instances of AppDelegate in both my MasterViewController and my NewFarmNamingView classes. The instance in the Master is to populate the table. The instance in NewFarm is to add the newly created Farm to the delegate. Code below.
Segments from class NewFarmNamingView:
- (IBAction) keyboardDonePushed:(id)sender
{
// create a Farm and add it to the delegate
NSString *text = newFarmTextField.text;
Farm *newFarm = [[Farm alloc] init];
[newFarm setFarmTitle:text];
[[delegate arrayOfFarms] addObject:newFarm];
[newFarm release];
NSLog(#"Added farm: %#" , text);
// dismiss the view
[self closeView:nil];
}
- (void)viewDidLoad
{
[super viewDidLoad];
// initialize the delegate
delegate = [[UIApplication sharedApplication] delegate];
}
Segments from the class Farm
- (void) setFarmTitle : (NSString *) _farmTitle
{
farmTitle = _farmTitle;
}
- (NSString *) getFarmTitle
{
return farmTitle;
}
// NSCoding Methods
- (void) encodeWithCoder:(NSCoder *)aCoder
{
[aCoder encodeObject:farmTitle forKey:#"kFarmTitle"];
}
- (id) initWithCoder:(NSCoder *)aDecoder
{
farmTitle = [aDecoder decodeObjectForKey:#"kFarmTitle"];
return self;
}
// Initialization method
- (id)init
{
self = [super init];
if (self) {
// Initialization code here.
}
return self;
}
From the runtime reference: "objc_msgsend sends a message to the receiver and expects a simple return value."
I'll bet you anything that what you're returning (if you're returning anything at all) in that class method getTitleFarm is returning an incorrect value. It should be an NSString. Be absolutely sure it is returning an NSString, and not anything else.
If you need to use the respondsToSelector method to see if the class is being released, try:
if([current respondsToSelector:#selector(getFarmTitles)]) {. [current getFarmTitle];
}
else {
NSLog:(#"FAILURE!!");
}
EDIT: maybe you are not retaining or even creating this string at all. In it's initialization, wrap it in a retain]; message
I have been trying for days to get this code to work, but I have no idea what I am doing wrong. Everytime the app wakes up from sleep, or the user closes the app and opens it again (without closing the app from multitasking), I want a label value to change.
In my applicationDidBecomeActive, I am running a counter, which I want to display on whatever viewcontroller is open at that moment.
Code:
- (void)applicationDidBecomeActive:(UIApplication *)application {
counter = counter + 1;
W1G1 *view1 = [[[W1G1 alloc] initWithNibName:#"W1G1" bundle:nil] retain];
[view1 setlabel];
}
In my viewcontroller W1G1, I have the following code:
Code:
- (void) setlabel {
NSString *string = [NSString stringWithFormat:#"%d", counter];
vocabword.text = string;
}
I have imported W1G1 in my appdelegate, but the code does not run :( Please help!
Thanks
In the AppDelegate.m file, where you have
- (void)applicationDidBecomeActive:(UIApplication *)application {
counter = counter + 1;
W1G1 *view1 = [[[W1G1 alloc] initWithNibName:#"W1G1" bundle:nil] retain];
[view1 setlabel];
}
the variable counter being incremented is confined to the AppDelegate. In other words, your view controller doesn't know that it has been incremented.
I would suggest that you use NSUserDefaults to store the value of counter so that you can easily pass it between these view controllers. Either that, or you could allow for an input into the method setLabel, e.g.
- (void) setlabel:(int)counter {
NSString *string = [NSString stringWithFormat:#"%d", counter];
vocabword.text = string;
}
and then in the AppDelegate you'll want to do:
- (void)applicationDidBecomeActive:(UIApplication *)application {
counter = counter + 1;
W1G1 *view1 = [[[W1G1 alloc] initWithNibName:#"W1G1" bundle:nil] retain];
[view1 setlabel:counter]; // <-- now you're using counter
[self.window addSubview:view1];
}
1) When you say 'the code does not run' do you mean that? That is, if you put NSLogs in applicationDidBecomeActive: and in setLabel does it show the code is run?
2) I would suspect the code is running. But your code won't "show the counter on whatever view controller is open at that moment". Your code creates a new view (view1), but that view won't be displayed. It is not added as a subview to anything. Your code will also leak. You create a W1G1 object, but it is never released and you throw away any reference you have to it.
To achieve what you want, you could add a subview to the application's window. Depending how your app delegate is set up, something like the following should do the trick:
counter++;
W1G1 *viewController1 = [[W1G1 alloc] initWithNibName:#"W1G1" bundle:nil];
[viewController1 setlabel: counter];
[[self window] addSubview: [viewController1 view]]
// you'll want to save a reference to the viewController somehow so you can release it at a later date
Then in W1G1
- (void) setlabel: (int) counter;
{
NSString *string = [NSString stringWithFormat:#"%d", counter];
vocabword.text = string;
}
There are, of course, lots of other approaches you could take towards this problem. And you'll need some strategy for removing the W1G1 view that you are adding at some stage, otherwise you'll just get more and more views added.
Update: You ask (in comments) how to keep track of your viewController throughout lifetime of the app... One approach is to keep track of it in your appDelegate. In the header have something like:
#class W1G1;
#interface MyAppDelegate : : NSObject <UIApplicationDelegate>
{
// other decelerations
int counter;
W1G1 * _myW1G1
}
#property (nonatomic, retain) W1G1* theW1G1
In the .m file include
#synthesize theW1G1 = _myW1G1;
Probably in application:didFinishLaunchingWithOptions: create the viewController, set the property to refer to it, and add its view to the view hierarchy.
W1G1* theViewController = [[W1G! alloc] initWithNibName: #"W1G1" bundle: nil];
[[self window] addSubview: [theViewController view]];
[self setTheW1G1: theViewController];
[theViewController release];
Then when you want to access the viewController again from with the app delegate use [self theW1G1], e.g.
[[self W1G1] setlabel: counter];
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;
