Implementations

impl GKMatchmakerViewController

pub unsafe fn matchmakerDelegate( &self, ) -> Option<Retained<ProtocolObject<dyn GKMatchmakerViewControllerDelegate>>>

pub unsafe fn setMatchmakerDelegate( &self, matchmaker_delegate: Option<&ProtocolObject<dyn GKMatchmakerViewControllerDelegate>>, )

Setter for matchmakerDelegate.

This is a weak property.

pub unsafe fn matchRequest(&self) -> Retained<GKMatchRequest>

Available on crate feature GKMatchmaker only.

pub unsafe fn isHosted(&self) -> bool

set to YES to receive hosted (eg. not peer-to-peer) match results. Will cause the controller to return an array of players instead of a match.

pub unsafe fn setHosted(&self, hosted: bool)

Setter for isHosted.

pub unsafe fn matchmakingMode(&self) -> GKMatchmakingMode

this controls which mode of matchmaking to support in the UI (all, nearby only, automatch only, invite only). Throws an exeption if you can not set to the desired mode (due to restrictions)

pub unsafe fn setMatchmakingMode(&self, matchmaking_mode: GKMatchmakingMode)

Setter for matchmakingMode.

pub unsafe fn canStartWithMinimumPlayers(&self) -> bool

A BOOL value to allow the GKMatchMakerViewController to return control to the game once the minimum number of players are connected. By default the value is NO, and the multiplayer match can only proceed after all players are connected. If the value is set to YES, then once the number of connected players is greater than or equal to minPlayers of the match request, matchmakerViewController:didFindMatch: will be called and the game can get the match instance, and update the game scene accordingly. The remaining players wil continue to connect.

pub unsafe fn setCanStartWithMinimumPlayers( &self, can_start_with_minimum_players: bool, )

Setter for canStartWithMinimumPlayers.

pub unsafe fn initWithMatchRequest( this: Allocated<Self>, request: &GKMatchRequest, ) -> Option<Retained<Self>>

Available on crate feature GKMatchmaker only.

Initialize with a matchmaking request, allowing the user to send invites and/or start matchmaking

pub unsafe fn initWithInvite( this: Allocated<Self>, invite: &GKInvite, ) -> Option<Retained<Self>>

Available on crate feature GKMatchmaker only.

Initialize with an accepted invite, allowing the user to see the status of other invited players and get notified when the game starts

pub unsafe fn addPlayersToMatch(&self, match: &GKMatch)

Available on crate feature GKMatch only.

Add additional players (not currently connected) to an existing peer-to-peer match. Apps should elect a single device to do this, otherwise conflicts could arise resulting in unexpected connection errors.

pub unsafe fn setHostedPlayer_didConnect( &self, player: &GKPlayer, connected: bool, )

Available on crate features GKBasePlayer and GKPlayer only.

pub unsafe fn defaultInvitationMessage(&self) -> Option<Retained<NSString>>

👎Deprecated: No longer supported.

deprecated, set the message on the match request instead

pub unsafe fn setDefaultInvitationMessage( &self, default_invitation_message: Option<&NSString>, )

👎Deprecated: No longer supported.

Setter for defaultInvitationMessage.

This is copied when set.

Methods from Deref<Target = NSObject>

pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !

Handle messages the object doesn’t recognize.

See Apple’s documentation for details.

Methods from Deref<Target = AnyObject>

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());

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T

where T: Encode,

👎Deprecated: this is difficult to use correctly, use 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.

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`
    }
}
