Implementations§
Source§impl EKEvent
impl EKEvent
Sourcepub unsafe fn eventWithEventStore(
event_store: &EKEventStore,
) -> Retained<EKEvent>
Available on crate feature EKEventStore
only.
pub unsafe fn eventWithEventStore( event_store: &EKEventStore, ) -> Retained<EKEvent>
EKEventStore
only.Creates a new autoreleased event object.
Sourcepub unsafe fn eventIdentifier(&self) -> Option<Retained<NSString>>
pub unsafe fn eventIdentifier(&self) -> Option<Retained<NSString>>
A unique identifier for this event.
This identifier can be used to look the event up using [EKEventStore eventWithIdentifier:]. You can use this not only to simply fetch the event, but also to validate the event has not been deleted out from under you when you get an external change notification via the EKEventStore database changed notification. If eventWithIdentifier: returns nil, the event was deleted.
Please note that if you change the calendar of an event, this ID will likely change. It is currently also possible for the ID to change due to a sync operation. For example, if a user moved an event on a different client to another calendar, we’d see it as a completely new event here.
This may be nil for events that have not been saved.
Sourcepub unsafe fn startDate(&self) -> Retained<NSDate>
pub unsafe fn startDate(&self) -> Retained<NSDate>
The start date for the event.
This property represents the start date for this event. Floating events (such as all-day events) are currently always returned in the default time zone. ([NSTimeZone defaultTimeZone])
This will be nil for new events until you set it.
Sourcepub unsafe fn setStartDate(&self, start_date: Option<&NSDate>)
pub unsafe fn setStartDate(&self, start_date: Option<&NSDate>)
Setter for startDate
.
Sourcepub unsafe fn endDate(&self) -> Retained<NSDate>
pub unsafe fn endDate(&self) -> Retained<NSDate>
The end date for the event.
This will be nil for new events until you set it.
Sourcepub unsafe fn setEndDate(&self, end_date: Option<&NSDate>)
pub unsafe fn setEndDate(&self, end_date: Option<&NSDate>)
Setter for endDate
.
Sourcepub unsafe fn structuredLocation(
&self,
) -> Option<Retained<EKStructuredLocation>>
Available on crate feature EKStructuredLocation
only.
pub unsafe fn structuredLocation( &self, ) -> Option<Retained<EKStructuredLocation>>
EKStructuredLocation
only.Allows you to set a structured location (a location with a potential geo-coordinate) on an event. The getter for EKEvent’s location property just returns the structured location’s title. The setter for EKEvent’s location property is equivalent to [event setStructuredLocation:[EKStructuredLocation locationWithTitle:…]].
Sourcepub unsafe fn setStructuredLocation(
&self,
structured_location: Option<&EKStructuredLocation>,
)
Available on crate feature EKStructuredLocation
only.
pub unsafe fn setStructuredLocation( &self, structured_location: Option<&EKStructuredLocation>, )
EKStructuredLocation
only.Setter for structuredLocation
.
Sourcepub unsafe fn compareStartDateWithEvent(
&self,
other: &EKEvent,
) -> NSComparisonResult
pub unsafe fn compareStartDateWithEvent( &self, other: &EKEvent, ) -> NSComparisonResult
Comparison function you can pass to sort NSArrays of EKEvents by start date.
Sourcepub unsafe fn organizer(&self) -> Option<Retained<EKParticipant>>
Available on crate feature EKParticipant
only.
pub unsafe fn organizer(&self) -> Option<Retained<EKParticipant>>
EKParticipant
only.The organizer of this event, or nil.
Sourcepub unsafe fn availability(&self) -> EKEventAvailability
pub unsafe fn availability(&self) -> EKEventAvailability
The availability setting for this event.
The availability setting is used by CalDAV and Exchange servers to indicate how the time should be treated for scheduling. If the calendar the event is currently in does not support event availability, EKEventAvailabilityNotSupported is returned.
Sourcepub unsafe fn setAvailability(&self, availability: EKEventAvailability)
pub unsafe fn setAvailability(&self, availability: EKEventAvailability)
Setter for availability
.
Sourcepub unsafe fn status(&self) -> EKEventStatus
pub unsafe fn status(&self) -> EKEventStatus
The status of the event.
While the status offers four different values in the EKEventStatus enumeration, in practice, the only actionable and reliable status is canceled. Any other status should be considered informational at best. You cannot set this property. If you wish to cancel an event, you should simply remove it using removeEvent:.
Sourcepub unsafe fn isDetached(&self) -> bool
pub unsafe fn isDetached(&self) -> bool
Represents whether this event is detached from a recurring series.
If this EKEvent is an instance of a repeating event, and an attribute of this EKEvent has been changed from the default value generated by the repeating event, isDetached will return YES. If the EKEvent is unchanged from its default state, or is not a repeating event, isDetached returns NO.
Sourcepub unsafe fn occurrenceDate(&self) -> Option<Retained<NSDate>>
pub unsafe fn occurrenceDate(&self) -> Option<Retained<NSDate>>
The occurrence date of an event if it is part of a recurring series.
This is only set if the event is part of a recurring series. It returns the date on which this event was originally scheduled to occur. For occurrences that are unmodified from the recurring series, this is the same as the start date. This value will remain the same even if the event has been detached and its start date has changed. Floating events (such as all-day events) are currently returned in the default time zone. ([NSTimeZone defaultTimeZone])
This will be nil for new events until you set startDate.
Sourcepub unsafe fn refresh(&self) -> bool
pub unsafe fn refresh(&self) -> bool
Refreshes an event object to ensure it’s still valid.
When the database changes, your application is sent an EKEventStoreChangedNotification note. You should generally consider all EKEvent instances to be invalid as soon as you receive the notification. However, for events you truly care to keep around, you can call this method. It ensures the record is still valid by ensuring the event and start date are still valid. It also attempts to refresh all properties except those you might have modified. If this method returns NO, the record has been deleted or is otherwise invalid. You should not continue to use it. If it returns YES, all is still well, and the record is ready for continued use. You should only call this method on events that are more critical to keep around if possible, such as an event that is being actively edited, as this call is fairly heavyweight. Do not use it to refresh the entire selected range of events you might have had selected. It is mostly pointless anyway, as recurrence information may have changed.
Sourcepub unsafe fn birthdayContactIdentifier(&self) -> Option<Retained<NSString>>
pub unsafe fn birthdayContactIdentifier(&self) -> Option<Retained<NSString>>
Specifies the contact identifier of the person this event was created for.
This property is only valid for events in the built-in Birthdays calendar. It specifies the contact identifier (for use with the Contacts framework) of the person this event was created for. For any other type of event, this property returns nil.
Sourcepub unsafe fn birthdayPersonID(&self) -> NSInteger
pub unsafe fn birthdayPersonID(&self) -> NSInteger
Specifies the address book ID of the person this event was created for.
This property is only valid for events in the built-in Birthdays calendar. It specifies the Address Book ID of the person this event was created for. For any other type of event, this property returns -1.
Sourcepub unsafe fn birthdayPersonUniqueID(&self) -> Option<Retained<NSString>>
👎Deprecated: Use birthdayContactIdentifier instead
pub unsafe fn birthdayPersonUniqueID(&self) -> Option<Retained<NSString>>
Specifies the address book unique ID of the person this event was created for.
This property is only valid for events in the built-in Birthdays calendar. It specifies the Address Book unique ID of the person this event was created for. For any other type of event, this property returns nil.
Methods from Deref<Target = EKCalendarItem>§
Sourcepub unsafe fn UUID(&self) -> Retained<NSString>
pub unsafe fn UUID(&self) -> Retained<NSString>
This is now deprecated; use calendarItemIdentifier instead.
Sourcepub unsafe fn calendar(&self) -> Option<Retained<EKCalendar>>
Available on crate feature EKCalendar
only.
pub unsafe fn calendar(&self) -> Option<Retained<EKCalendar>>
EKCalendar
only.The calendar that this calendar item belongs to.
This will be nil for new calendar items until you set it.
Sourcepub unsafe fn setCalendar(&self, calendar: Option<&EKCalendar>)
Available on crate feature EKCalendar
only.
pub unsafe fn setCalendar(&self, calendar: Option<&EKCalendar>)
EKCalendar
only.Setter for calendar
.
Sourcepub unsafe fn calendarItemIdentifier(&self) -> Retained<NSString>
pub unsafe fn calendarItemIdentifier(&self) -> Retained<NSString>
A unique identifier for a calendar item.
Item identifiers are not sync-proof in that a full sync will lose this identifier, so you should always have a back up plan for dealing with a reminder that is no longer fetchable by this property, e.g. by title, etc. Use [EKEventStore calendarItemWithIdentifier:] to look up the item by this value.
Sourcepub unsafe fn calendarItemExternalIdentifier(
&self,
) -> Option<Retained<NSString>>
pub unsafe fn calendarItemExternalIdentifier( &self, ) -> Option<Retained<NSString>>
A server-provided identifier for this calendar item
This identifier, provided by the server, allows you to reference the same event or reminder across multiple devices. For calendars stored locally on the device, including the birthday calendar, it simply passes through to calendarItemIdentifier.
This identifier is unique as of creation for every calendar item. However, there are some cases where duplicate copies of a calendar item can exist in the same database, including:
- A calendar item was imported from an ICS file into multiple calendars
- An event was created in a calendar shared with the user and the user was also invited to the event
- The user is a delegate of a calendar that also has this event
- A subscribed calendar was added to multiple accounts In such cases, you should choose between calendar items based on other factors, such as the calendar or source.
This identifier is the same for all occurrences of a recurring event. If you wish to differentiate between occurrences, you may want to use the start date.
This may be nil for new calendar items that do not yet belong to a calendar.
In addition, there are two caveats for Exchange-based calendars:
- This identifier will be different between EventKit on iOS versus OS X
- This identifier will be different between devices for EKReminders
Sourcepub unsafe fn title(&self) -> Retained<NSString>
pub unsafe fn title(&self) -> Retained<NSString>
The title of this calendar item.
This will be an empty string for new calendar items until you set it.

Sourcepub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !
Handle messages the object doesn’t recognize.
See Apple’s documentation for details.
Methods from Deref<Target = AnyObject>§
Sourcepub fn class(&self) -> &'static AnyClass
pub fn class(&self) -> &'static AnyClass
Dynamically find the class of this object.
§Panics
May panic if the object is invalid (which may be the case for objects
returned from unavailable init
/new
methods).
§Example
Check that an instance of NSObject
has the precise class NSObject
.
use objc2::ClassType;
use objc2::runtime::NSObject;
let obj = NSObject::new();
assert_eq!(obj.class(), NSObject::class());
Sourcepub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
👎Deprecated: this is difficult to use correctly, use Ivar::load
instead.
pub unsafe fn get_ivar<T>(&self, name: &str) -> &Twhere
T: Encode,
Ivar::load
instead.Use Ivar::load
instead.
§Safety
The object must have an instance variable with the given name, and it
must be of type T
.
See Ivar::load_ptr
for details surrounding this.
Sourcepub fn downcast_ref<T>(&self) -> Option<&T>where
T: DowncastTarget,
pub fn downcast_ref<T>(&self) -> Option<&T>where
T: DowncastTarget,
Attempt to downcast the object to a class of type T
.
This is the reference-variant. Use Retained::downcast
if you want
to convert a retained object to another type.
§Mutable classes
Some classes have immutable and mutable variants, such as NSString
and NSMutableString
.
When some Objective-C API signature says it gives you an immutable class, it generally expects you to not mutate that, even though it may technically be mutable “under the hood”.
So using this method to convert a NSString
to a NSMutableString
,
while not unsound, is generally frowned upon unless you created the
string yourself, or the API explicitly documents the string to be
mutable.
See Apple’s documentation on mutability and on
isKindOfClass:
for more details.
§Generic classes
Objective-C generics are called “lightweight generics”, and that’s because they aren’t exposed in the runtime. This makes it impossible to safely downcast to generic collections, so this is disallowed by this method.
You can, however, safely downcast to generic collections where all the
type-parameters are AnyObject
.
§Panics
This works internally by calling isKindOfClass:
. That means that the
object must have the instance method of that name, and an exception
will be thrown (if CoreFoundation is linked) or the process will abort
if that is not the case. In the vast majority of cases, you don’t need
to worry about this, since both root objects NSObject
and
NSProxy
implement this method.
§Examples
Cast an NSString
back and forth from NSObject
.
use objc2::rc::Retained;
use objc2_foundation::{NSObject, NSString};
let obj: Retained<NSObject> = NSString::new().into_super();
let string = obj.downcast_ref::<NSString>().unwrap();
// Or with `downcast`, if we do not need the object afterwards
let string = obj.downcast::<NSString>().unwrap();
Try (and fail) to cast an NSObject
to an NSString
.
use objc2_foundation::{NSObject, NSString};
let obj = NSObject::new();
assert!(obj.downcast_ref::<NSString>().is_none());
Try to cast to an array of strings.
use objc2_foundation::{NSArray, NSObject, NSString};
let arr = NSArray::from_retained_slice(&[NSObject::new()]);
// This is invalid and doesn't type check.
let arr = arr.downcast_ref::<NSArray<NSString>>();
This fails to compile, since it would require enumerating over the array to ensure that each element is of the desired type, which is a performance pitfall.
Downcast when processing each element instead.
use objc2_foundation::{NSArray, NSObject, NSString};
let arr = NSArray::from_retained_slice(&[NSObject::new()]);
for elem in arr {
if let Some(data) = elem.downcast_ref::<NSString>() {
// handle `data`
}
}
