This is my scenario:
I am adding an event to iOS calender from my app. Just before adding the event (add event view of calendar is being shown ), if user go to settings-->general-->restrictions-->calendar and restrict my app's permission the app crashes.
Have anyone came across an issue like this? Any leads? because xcode isn't giving any relates log while crashing. I am running app in iOS 6.0 iPod Touch.
Hope some can help.
First get permission to access calendar events and then add event.
Code to get permission
EKEventStore eventStore = [[EKEventStore alloc] init];
if ([eventStore respondsToSelector:#selector(requestAccessToEntityType:completion:)])
{
[eventStore requestAccessToEntityType:EKEntityTypeEvent completion:^(BOOL granted, NSError *error)
{
if (granted){
MLLog(#"Wipe : getEventStorePermission : permission granted");
}
else{
MLLog(#"Wipe : getEventStorePermission : permission not granted");
}
}];
}
else{
MLLog(#"Wipe : getEventStorePermission : permission not required");
}
RELEASE_OBJECT(eventStore)

How can I check if the user denied or accepted the push notification permission message in ios in codenameone or native?
Both Android and iOS have API's to detect if push is enabled:
Push Notification ON or OFF Checking in iOS
Android 4.1: How to check notifications are disabled for the application?
Since those were added relatively recently and we didn't get enough demand for that we don't support them at this time. You can probably invoke them with a native interface or submit a pull request with integration. Normally you would get a push registered callback when push works and an error or nothing if it doesn't.
I found a solution implementing a funtion native to IOS 10
This methods are working perfectly in Objective-c and codenameone code
//------------------------------------------------------------------------------
//This method is use to check if the user enable or disable push notification
//------------------------------------------------------------------------------
-(BOOL)isPushNotificationIsEnable{
if ([[UIApplication sharedApplication] isRegisteredForRemoteNotifications]) {
NSLog(#"isPushNotificationIsEnable()->YES");
return YES;
} else {
NSLog(#"isPushNotificationIsEnable()->NO");
return NO;
}
}
//------------------------------------------------------------------------------
//This method is use to launch the Notification screen of your app
//------------------------------------------------------------------------------
Display.getInstance().execute("App-Prefs:root=NOTIFICATIONS_ID&path=your package name app", new ActionListener() {
String methodName = "startLocationSetting";
#Override
public void actionPerformed(ActionEvent evt) {
boolean status = Utils.isPushNotificationEnable();
}
});
//------------------------------------------------------------------------------
-(void)viewDidAppear:(BOOL)animated
{
[super viewDidAppear:animated];
if ([HKHealthStore isHealthDataAvailable]){
NSSet *writeDataTypes = [self dataTypesToWrite];
NSSet *readDataTypes = [self dataTypesToRead];
[self.healthStore requestAuthorizationToShareTypes:writeDataTypes readTypes:readDataTypes completion:^(BOOL success, NSError *error) {
NSLog(#"%s",__func__);
if (!success) {
NSLog(#"You didn't allow HealthKit to access these read/write data types. In your app, try to handle this error gracefully when a user decides not to provide access. The error was: %#. If you're using a simulator, try it on a device.", error);
return;
}
dispatch_async(dispatch_get_main_queue(), ^{
// Update the user interface based on the current user's health information.
NSLog(#"=========================== %s",__func__);
});
}];
}
}
requestAuthorizationToShareTypes does not calling back completion method.
I had a similar issue with the permissions box not appearing and hadn't set up the HKHealthStore properly, putting this beforehand fixed it for me
self.healthStore = [[HKHealthStore alloc] init];
Here is a sample implementation that returns types instead of strings as described in the comment section.
-(NSSet*)datatypesToWrite {
NSArray *quantityTypes =
#[HKQuantityTypeIdentifierHeartRate,
HKQuantityTypeIdentifierBodyTemperature,
HKQuantityTypeIdentifierBloodPressureSystolic,
HKQuantityTypeIdentifierBloodPressureDiastolic,
HKQuantityTypeIdentifierRespiratoryRate];
NSMutableArray *hkTypes = [[NSMutableArray alloc] init];
for (NSString *identifier in quantityTypes) {
HKQuantityType *quantType =
[HKObjectType quantityTypeForIdentifier:identifier];
[hkTypes addObject:quantType];
}
// Make sure the types are of the correct style (Quantity, Category, Etc.)
HKCategoryType *catType =
[HKObjectType categoryTypeForIdentifier:HKCategoryTypeIdentifierSleepAnalysis];
[hkTypes addObject:catType];
return [[NSSet alloc] initWithArray:hkTypes];
}
Each time you request new types for the first time the modal permissions dialog will show up (but it won't show up again if you re-prompt for permissions not granted). Apple's guidelines are to prompt for everything you might need, but it feels a bit against best practices to me to request 12 types up front if I know somebody only asked to save into a few of them.
I want to display the video in landscape mode only when video is playing in fullscreen using MPMoviePlayerController in ios6. My application supports only portrait mode.
Can anybody please suggest me, how can i do this?
Thanks.
I got the answer from below link
iOS 6 MPMoviePlayerViewController and presentMoviePlayerViewControllerAnimated Rotation
Make changes in application delegate file as fllows and its working:
Only change the UIview name as MPSwipableView in ios6
- (NSUInteger) application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
if ([[self.window.subviews.lastObject class].description isEqualToString:#"MPSwipableView"]) {
return UIInterfaceOrientationMaskAllButUpsideDown;
}
else {
return UIInterfaceOrientationMaskPortrait;
}
}
In your viewController, implement this method,
-(NSUInteger)supportedInterfaceOrientations
{
return UIInterfaceOrientationMaskLandscape
}
I am implementing an Universal application. In my application I need to Autorotate the screen for the iPad only not for the iPhone. How can I do that? I tried with the following code but it is not working.
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return NO;
}
Finally I made it by making changes to the properties in plist file.
After struggling to set in UIViewController's shouldAutorotate and supportedInterfaceOrientation methods, with no success in iOS6, I found the most effective is to set it in app delegate.
- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window
{
return UIInterfaceOrientationMaskPortrait;
}
However returning UIInterfaceOrientationMaskPortraitUpsideDown was crashing my app. I don't know what I was doing wrong!
When using the authenticateHandler in iOS 6, game center won't present the login view if the user cancels it. I realize game center will auto lockout an app after 3 cancel attempts, but I'm talking about just 2 attempts. If they cancel the login, they have to leave the app and come back before game center will present the login even through the authenticateHandler is getting set again. Any ideas on how to handle this case in iOS 6?
It works fine when using the older authenticateWithCompletionHandler method:
#if __IPHONE_OS_VERSION_MIN_REQUIRED >= __IPHONE_6_0
GKLocalPlayer.localPlayer.authenticateHandler = authenticateLocalPlayerCompleteExtended;
#else
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:authenticateLocalPlayerComplete];
#endif
The reason this is important for my app is that it requires Game Center for multi-player. The app tries to authenticate to game center on launch, but if the user cancels we don't ask them at launch again so they won't get nagged. What we do is show a Game Center Login button if they aren't logged in when they select multi-player. The login button forces a game center login by calling authenticateWithCompletionHandler (and now by setting GKLocalPlayer.localPlayer.authenticateHandler again).
Better use runtime checks (instancesRespondToSelector:) instead of preprocessor #if statements, so that you can use recommended methods where they are available and depreciated ones elsewhere. I actually found I need to distinguish three cases before setting the invite handler, as the authentication handler might also get called with a nil view controller:
-(void)authenticateLocalPlayer
{
if ([[GKLocalPlayer class] instancesRespondToSelector:#selector(setAuthenticateHandler:)]) {
[[GKLocalPlayer localPlayer] setAuthenticateHandler:^(UIViewController *gameCenterLoginViewController, NSError *error) {
if (gameCenterLoginViewController) {
[self.presentedViewController presentViewController:gameCenterLoginViewController
animated:YES
completion:^{
[self setInviteHandlerIfAuthenticated];
}];
} else {
[self setInviteHandlerIfAuthenticated];
}
}];
} else { // alternative for iOS < 6
[[GKLocalPlayer localPlayer] authenticateWithCompletionHandler:^(NSError *error) {
[self setInviteHandlerIfAuthenticated];
}];
}
}
Yet more cases must be distinguished within the invite handler, as matchForInvite:: is new in iOS6 as well and avoids yet another round through game center view controllers:
-(void)setInviteHandlerIfAuthenticated
{
if ([GKLocalPlayer localPlayer].isAuthenticated) {
[GKMatchmaker sharedMatchmaker].inviteHandler = ^(GKInvite *acceptedInvite, NSArray *playersToInvite) {
if (acceptedInvite) {
if ([GKMatchmaker instancesRespondToSelector:#selector(matchForInvite:completionHandler:)]) {
[self showInfoAnimating:YES completion:NULL];
[[GKMatchmaker sharedMatchmaker] matchForInvite:acceptedInvite
completionHandler:^(GKMatch *match, NSError *error) {
// ... handle invited match
}];
} else {
// alternative for iOS < 6
GKMatchmakerViewController *mmvc = [[[GKMatchmakerViewController alloc] initWithInvite:acceptedInvite] autorelease];
mmvc.matchmakerDelegate = self;
// ... present mmvc appropriately
// ... handle invited match found in delegate method matchmakerViewController:didFindMatch:
}
} else if (playersToInvite) {
// ... handle match initiated through game center
}
};
}
}
Let me know if this helps.
I dont' think this is possible in iOS 6.0. There were API calls to do this in the early SDK builds that were removed before release.
In the WWDC 2012 Video: Session 516 - Integrating Your Games with Game Center [8:30] They actually show code where you call an authenticate method:
GKLocalPlayer *localPlayer = [GKLocalPlayer localPlayer];
localPlayer.authenticationHandler = //handle the callback...
[localPlayer authenticate];
This method is now private API but you can see it in action by calling:
[[GKLocalPlayer localPlayer] performSelector:#selector(_authenticate)];
It does exactly what you want, but can't be used because it's now private.
You can also trigger the authentication process by posting the UIApplicationWillEnterForegroundNotification notification:
[[NSNotificationCenter defaultCenter] postNotificationName:UIApplicationWillEnterForegroundNotification object:[UIApplication sharedApplication]];
I assume it would be unadvisable to do this in live code.
