pub unsafe fn viewWillAppear(&self, animated: bool)

Called when the view is about to made visible, before it is added to the hierarchy. Because the view is not yet in the hierarchy at the time this method is called, it is too early in the appearance transition for many usages. Prefer -viewIsAppearing: instead of this method when possible. Only use this method when its exact timing before the appearance transition starts running is desired, such as to set up an alongside animation with a transition coordinator, or as a counterpart for paired code in a viewWillDisappear/viewDidDisappear callback that does not rely on the view or view controller’s trait collection or the view hierarchy.

pub unsafe fn viewIsAppearing(&self, animated: bool)

Called when the view is becoming visible at the beginning of the appearance transition, after it has been added to the hierarchy and been laid out by its superview. This method is very similar to -viewWillAppear: and is always called shortly afterwards (so changes made in either callback will be visible to the user at the same time), but unlike -viewWillAppear:, at the time when -viewIsAppearing: is called all of the following are valid for the view controller and its own view:

• View controller and view’s trait collection
• View’s superview chain and window
• View’s geometry (e.g. frame/bounds, safe area insets, layout margins) Choose this method instead of -viewWillAppear: by default, as it is a direct replacement that provides equivalent or superior behavior in nearly all cases.

pub unsafe fn viewDidAppear(&self, animated: bool)

Called after the view has fully transitioned to visible, when any transition animations have completed.

pub unsafe fn viewWillDisappear(&self, animated: bool)

Called when the view is about to be dismissed, covered, or otherwise hidden.

pub unsafe fn viewDidDisappear(&self, animated: bool)

Called after the view has fully been dismissed, covered, or otherwise hidden, when any transition animations have completed.

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`
    }
}

impl UIFocusEnvironment for MSStickerBrowserViewController

unsafe fn preferredFocusEnvironments( &self, ) -> Retained<NSArray<ProtocolObject<dyn UIFocusEnvironment>>>

where Self: Sized + Message,

The preferred focus environments define where to search for the default focused item in an environment, such as when focus updates programmatically. Starting from the target environment, each preferred focus environment is recursively searched in the order of the array until an eligible, focusable item is found. Preferred focus environments can include focusable and non-focusable items, in addition to non-item environments. Returning an empty array is equivalent to returning an array containing only ‘self’.

unsafe fn setNeedsFocusUpdate(&self)

where Self: Sized + Message,

Marks this environment as needing a focus update, which if accepted will attempt to reset focus to this environment, or one of its preferred focus environments, on the next update cycle. If this environment does not currently contain the focused item, then calling this method has no effect. If a parent of this environment is also requesting focus, then this environment’s request is rejected in favor of the parent’s. NOTE: If you provide your own implementation, it must call [[UIFocusSystem focusSystemForEnvironment:self] requestFocusUpdateToEnvironment:self];

unsafe fn updateFocusIfNeeded(&self)

where Self: Sized + Message,

Forces focus to be updated immediately. If there is an environment that has requested a focus update via -setNeedsFocusUpdate, and the request was accepted, then focus will be updated to that environment or one of its preferred focus environments. NOTE: If you provide your own implementation, it must call [[UIFocusSystem focusSystemForEnvironment:self] updateFocusIfNeeded];.

Asks whether the system should allow a focus update to occur.
