I am trying to save an event to iPhone calendar also to delete when user deletes the event. following is the code I am using for creating and editing an event .
// Upon selecting an event, create an EKEventViewController to display the event.
EKEventEditViewController *editController = [[EKEventEditViewController alloc] init];
editController.event = [eventsList objectAtIndex:indexPath.row];
editController.eventStore = self.eventStore;
editController.editViewDelegate = self;
itsSelectedReminder = indexPath.row;
isReminderDeleted = TRUE;
[editController.navigationBar setTintColor:[UIColor colorWithRed:67/255.0 green:114/255.0 blue:18/255.0 alpha:1]];
[self presentModalViewController:editController animated:YES];
[editController release];
[tableView deselectRowAtIndexPath:indexPath animated:YES];
Then When the user does any action add, edit or delete I am catching the event using the follwoing code.
- (void)eventEditViewController:(EKEventEditViewController *)controller
didCompleteWithAction:(EKEventEditViewAction)action {
It works perfect for add and edit however when I tried to delete It is calling the method several times so that makes my app crash. Any help is greatly appreciated. Please help as soon as possible.
Thanks in advance
Regards,
Dilip...
Set the editViewDelegate of the controller to nil immediately on completion.
func eventEditViewController(controller: EKEventEditViewController, didCompleteWithAction action: EKEventEditViewAction) {
// prevent additional calls for the same action
controller.editViewDelegate = nil
// whatever else you want to do
dismissViewControllerAnimated(true) {
}
...
}

I am using an ABNewPersonViewController to create a person. Everything works fine so far. I do set multivalue properties as well as single values. After tapping "Add" the contact can be found in the adressbook.
But there is a problem when editing this contact. After adding the contact to the adressbook, I save the addressbookID, so that I am able to identfiy if the contact is still saved in the AB.
So If the user wants to export a contact again, I do not create a new ABPersonRecordRef, but using the existing one identified by the id I have saved before:
ABRecordID recordId = [aContact.addressBookRecordId intValue];
ABRecordRef personRecord = nil;
if(recordId != 0) {
personRecord = ABAddressBookGetPersonWithRecordID(addressBook, recordId);
if(personRecord) {
return personRecord;
} else {
personRecord = ABPersonCreate();
}
} else {
personRecord = ABPersonCreate();
}
//set properties etc.
The problem now is, that this just works the first time. If the user displays the person a second time in the ABNewPersonViewController and taps on Cancel, the record will be deleted in the adress book. Although it was previously saved fine.
I tried using an ABUnknownPersonViewController, but the problem is that it seems that the attributes det on the recordRef are not displayed exactly like in the ABNewPersonViewController.
Any suggestions?
Though this thread is old, it might help others. Try to override the cancel event as shown here. It worked for me.
- (void)showNewPersonViewController:(ABRecordRef)person
{
//show new Person view controller
ABNewPersonViewController *vcNewPerson = [[ABNewPersonViewController alloc] init];
vcNewPerson.newPersonViewDelegate = self;
vcNewPerson.displayedPerson = person;
vcNewPerson.navigationItem.leftBarButtonItem = [[UIBarButtonItem alloc] initWithBarButtonSystemItem:UIBarButtonSystemItemCancel target:self action:#selector(onNewPersonCancelClick)];
[self.navigationController pushViewController:vcNewPerson animated:YES];
[vcNewPerson release];
}
- (void)onNewPersonCancelClick
{
[self dismissViewControllerAnimated:YES completion:nil];
}

I have a table view, and I use UILongPressGestureRecognizer on table view cell to show a context menu over the cell to allow user perform some extra functionality. Everything is work well in iOS 5.1, but when I test in iOS 5 and 4.3, the event is not fired.
Does anyone know how to solve this problem please help me, thanks in advance.
Below is my code:
in tableViewCell.h: add UIGestureRecognizerDelegate
in tableViewCell.m
UILongPressGestureRecognizer *longPressRecognizer = [[UILongPressGestureRecognizer alloc]
initWithTarget:self action:#selector(handleLongPress:)];
longPressRecognizer.minimumPressDuration = 1.5;
longPressRecognizer.numberOfTouchesRequired = 1;
longPressRecognizer.numberOfTapsRequired = 0;
longPressRecognizer.delegate = self;
[self addGestureRecognizer:longPressRecognizer];
[longPressRecognizer release];
// Method to handle event
- (void)handleLongPress:(UILongPressGestureRecognizer *)gestureRecognizer
{
if (gestureRecognizer.state == UIGestureRecognizerStateBegan)
{
// Do something.
}
}
After spending 1.5 days on this issue, I discover that somehow the tableView receives long press event but tableViewCell does not on iOS 5/4.3 . So I fixed this issue by adding UILongPressGuestureRecognizer to tableView then in the long press event handler then call tableViewCell to show the context menu, and it works.
I met this problem too. I found that long press gesture recognizer works fine only when 'delegate' property is 'NULL'. So just try to remove this line.
longPressRecognizer.delegate = self;
I have recently set-up an in-app purchase mechanism in my app. During the purchase i would like to update an hud (i am using the mbprogresshud) according to two kinds of events: i start a purchase and i receive a validation of the purchase. The problem i am facing is that the hud is never updated with the one i want when the purchase is done (custom view):
When i click on the purchase button:
-(IBAction)buyButtonTapped:(id)sender {
self.hud = [[SCLProgressHUD alloc] initWithView:self.view];
[self.view addSubview:self.hud];
self.hud.labelText = #"Connecting...";
self.hud.minSize = CGSizeMake(100 , 100);
[self.hud show:YES];
...
}
When i receive a notification that the purchase was successful:
-(void)productPurchased:(NSNotification *)notification {
self.hud.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"checkmark_icon.png"]];
self.hud.mode = SCLProgressHUDModeCustomView;
self.hud.labelText = #"Thanks for your purchase!";
...
}
Setting the self.hud.customView property in the last method will trigger a [self setNeedsLayout]; and [self setNeedsDisplay] within the hud class but still i don't observe any change.
Any possible idea of what i am doing wrong here?
As mentioned on the mbprogress hud readme, update of the UI when tasks are performed on the main thread required a slight delay to take effect. What happen in my case is that the hud was a strong property of a popover controller that i dismiss immediately so i didn't get a chance to see the update happening. I now dismiss the controller in the completion block of:
-(void)showAnimated:(BOOL)animated
whileExecutingBlock:(dispatch_block_t)block completionBlock:(void
(^)())completion
And my code snippet look like like this for the dismiss:
[_hud showAnimated:YES whileExecutingBlock:^(void){
[self.successPurchaseSoundEffect play];
_hud.customView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:#"checkmark_icon.png"]];
_hud.mode = SCLProgressHUDModeCustomView;
_hud.labelText = #"Thanks!";
// We need to pause the background thread to let the music play and the hud be updated
sleep(1);}
completionBlock:^(void){
[self.delegate dismissPurchaseInfoController:self];
}];
Hi
I am adding a "post comment section in my iPhone APP"
rest all things are working fine but when I tap on "postController textView" a keyboard is suppose to appear from the bottom but it is not appearing However the cursor is displaying and the text that I am passing using postController.textView.text = #"" is also displaying.
Please suggest the areas to be looked for fixing this bug.
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
above is the code that is giving call to the Three20 PostController
below is the calling method which is unchanged...
-(IBAction)postComment:(id)sender
{
[UserManager instance]authenticateUserAndProceed:self withSelector:#selector(showCommentView)];
}
-(void)showCommentView
{
TTPostController *postController = [[TTPostController alloc] init];
// self must implement the TTPostControllerDelegate protocol
postController.delegate = self;
self.popupViewController = postController;
// assuming self to be the current UIViewController
postController.superController = self;
postController.textView.text=#"temporary text";
[postController showInView:self.view animated:YES];
[postController release];
}
changed method
-(void)authenticateUserAndProceed:(id)parent withSelector:(SEL)selector
{
theParentViewController = parent;
self.theFunctionToCall = selector;
if(userid == nil)
{
GetUserInfoViewController *guivc = [[GetUserInfoViewController alloc] init];
[parent presentModalViewController:guivc animated:YES];
guivc.delegate = self;
[guivc release];
}
else {
//////////////////// below line was replaced///////////
// 2. [theParentViewController performSelector:selector];
// with below code
UIAlertView *alert =[[UIAlertView alloc]initWith Title........
[alert show];
}
}
PROBLEM SUMMARY:
as soon as the user registered, he was not able to the kyboard for the TTPostController
CHANGE SUMMARY:
As soon as the user is registered the call to
[theParentViewController performSelector:selector];
is not sent directly but the call goes to ann alertview which inter calls it.
EFETCS SUMMARY:
the user will see a "you are registered successfully" (kind of) alertview.
tapping OK on which, he will be sent to TTPostController. (this time the keyboard is appearing)
I kept the line# 2 in the AlertViewDelegate method.
I was amazed o see it working just by not calling the line 2 directly.
this worked for me.
I welcome any new and better idea to implement the same
I have implemented an app that shows a map with a lot of pins on it.
If you push one pin you get on a second view that shows the data behind the pin.
A button takes you back to the map.
My problem is that by the third touch on a pin the program crashes with a EXC_BAD_ACCESS in this method:
- (void) switchViews {
if(self.details == nil){
Kundendetails *detailAnsicht = [[Kundendetails alloc] initWithNibName:#"ViewList" bundle:nil];
detailAnsicht.rootViewController = self;
self.details = detailAnsicht;
detailAnsicht.map = self.map;
}
if(self.details.view.superview == nil) {
[map.view removeFromSuperview];
[self.view addSubview:details.view];
[details viewDidLoad];
} else {
[details.view removeFromSuperview];
[details release];
[self.view addSubview:map.view];
}
}
How do I isolate which line of code causes the crash? Why would it always crash only on the third touch?
I hope you could help me.
Put NSLog statements in each branch of the ifs. You will almost assuredly see that this statement causes the problem:
[details viewDidLoad];
This is because at some point you execute this:
[details release];
effectively making details inaccessible. By the way you should also almost NEVER call viwewDidLoad directly.
