pub unsafe fn minimumContentSizeCategory( &self, ) -> Option<Retained<UIContentSizeCategory>>

Available on crate feature UIContentSizeCategory only.

Specify content size category limits. Setting one or both of these properties will limit the content size category for this view (and its subviews) to a minimum or a maximum value. You can use this to limit the support content size categories on part of your view hierarchy. Setting this to nil removes the limit on the minimum or maximum. Limits will be applied immediately and when future content size category updates occur.

Specifying a minimum limit that is greater than the maximum limit (or vice versa) will effectively only use the maximum limit.

Example:

// limit the support content size categories between .medium and .accessibilityExtraLarge (included). view.minimumContentSizeCategory = UIContentSizeCategoryMedium; view.maximumContentSizeCategory = UIContentSizeCategoryAccessibilityExtraLarge;

pub unsafe fn setMinimumContentSizeCategory( &self, minimum_content_size_category: Option<&UIContentSizeCategory>, )

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

Available on crate feature UIIndirectScribbleInteraction only.

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.

Available on crate feature UIIndirectScribbleInteraction only.

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,

Available on crate feature UIIndirectScribbleInteraction only.

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 UIDatePicker

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

where Self: Sized + Message,

Available on crate feature UIFocus only.

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 parentFocusEnvironment( &self, ) -> Option<Retained<ProtocolObject<dyn UIFocusEnvironment>>>

where Self: Sized + Message,

Available on crate feature UIFocus only.

The parent focus environment of this environment, or nil if no parent exists. NOTE: If you implement this method, you must return a non-nil value for parent focus environment, otherwise your focus environment will not participate in focus interactions.

unsafe fn focusItemContainer( &self, ) -> Option<Retained<ProtocolObject<dyn UIFocusItemContainer>>>

where Self: Sized + Message,

Available on crate feature UIFocus only.

The container of any child focus items in this focus environment, or nil if no container exists.

unsafe fn setNeedsFocusUpdate(&self)

where Self: Sized + Message,

Available on crate feature UIFocus only.

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,

Available on crate feature UIFocus only.

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];.

unsafe fn shouldUpdateFocusInContext( &self, context: &UIFocusUpdateContext, ) -> bool

where Self: Sized + Message,

Available on crate feature UIFocus only.

unsafe fn didUpdateFocusInContext_withAnimationCoordinator( &self, context: &UIFocusUpdateContext, coordinator: &UIFocusAnimationCoordinator, )

where Self: Sized + Message,

Available on crate features UIFocus and UIFocusAnimationCoordinator only.

Called when the screen’s focused item has been updated to a new item. Use the animation coordinator to schedule focus-related animations in response to the update.

unsafe fn soundIdentifierForFocusUpdateInContext( &self, context: &UIFocusUpdateContext, ) -> Option<Retained<UIFocusSoundIdentifier>>

where Self: Sized + Message,

Available on crate feature UIFocus only.

Specifies an identifier corresponding to a sound that should be played for a focus update. Return UIFocusSoundIdentifierNone to opt out of sounds, UIFocusSoundIdentifierDefault for the system default sounds, a previously registered identifier for a custom sound, or nil to defer the decision to the parent.

unsafe fn preferredFocusedView(&self) -> Option<Retained<UIView>>

where Self: Sized + Message,

👎Deprecated

Available on crate features UIResponder and UIView and UIFocus only.

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

where Self: Sized + Message,

Available on crate feature UIFocus only.

The identifier of the focus group that this view belongs to. If this is nil, subviews inherit their superview’s focus group.

impl UIFocusItem for UIDatePicker

unsafe fn canBecomeFocused(&self) -> bool

where Self: Sized + Message,

Available on crate feature UIFocus only.

Indicates whether or not this item is currently allowed to become focused. Returning NO restricts the item from being focusable, even if it is visible in the user interface. For example, UIControls return NO if they are disabled.

unsafe fn frame(&self) -> CGRect

where Self: Sized + Message,

Available on crate features UIFocus and objc2-core-foundation only.

The geometric frame of this item, represented in the coordinateSpace of the UIFocusItemContainer in which it is contained.

unsafe fn focusEffect(&self) -> Option<Retained<UIFocusEffect>>

where Self: Sized + Message,

Available on crate features UIFocus and UIFocusEffect only.

Describes a visual effect to apply when this item is focused. When not implemented, the system may create a default effect for this item. Returning nil indicates that the system should not apply any visual effects, and that the app will handle applying the appropriate visuals.

unsafe fn focusGroupPriority(&self) -> UIFocusGroupPriority

where Self: Sized + Message,

Available on crate feature UIFocus only.

The priority this item has in its focus group. The higher the priority, the more likely it is to get picked when focus moves into this group. Note: this method can only be used to increase an item’s priority, not decrease it. For example if an item is currently selected, the actual priority of this item will be determined by MAX(focusGroupPriority, UIFocusGroupPrioritySelected).

unsafe fn focusItemDeferralMode(&self) -> UIFocusItemDeferralMode

where Self: Sized + Message,

Available on crate feature UIFocus only.

If this property is present and returns UIFocusItemDeferralModeNever, the focus deferral will not be enabled again after the user engagement timeout has expired if this item is currently focused and programmatic focus updates pointing to this item will be executed immediatly. If it returns UIFocusItemDeferralModeAlways focus will always be deferred when this item is supposed to be focused. Does nothing when focus deferral is not supported on the platform.

unsafe fn isTransparentFocusItem(&self) -> bool

where Self: Sized + Message,

Available on crate feature UIFocus only.

If this returns YES, the focus item is considered transparent in terms of occlusion. Items that are behind it are focusable. This value is ignored when the item is focusable, in which case the item is never considered transparent.

unsafe fn didHintFocusMovement(&self, hint: &UIFocusMovementHint)

where Self: Sized + Message,

Available on crate features UIFocus and UIFocusMovementHint only.

Called whenever this focus item is hinting to the user a focus movement might occur. The provided object is mutated by the focus engine whenever the user’s finger moves.

impl UIFocusItemContainer for UIDatePicker

unsafe fn coordinateSpace( &self, ) -> Retained<ProtocolObject<dyn UICoordinateSpace>>

where Self: Sized + Message,

Available on crate features UIFocus and UIView only.

The coordinate space of the focus items contained in this container. The focus items returned by focusItemsInRect: should report their frames in this coordinate space. If you are implementing this protocol, you may find it convenient to return the UIScreen as your coordinate space, and ensure that your contained items report their frames in screen space. Similarly, you might find that your focus items’ containing UIView or UIWindow is the most convenient coordinate space to use. You may also choose to implement your own object that conforms to UICoordinateSpace, if that is the most natural solution for your architecture.

unsafe fn focusItemsInRect( &self, rect: CGRect, ) -> Retained<NSArray<ProtocolObject<dyn UIFocusItem>>>

where Self: Sized + Message,

Available on crate features UIFocus and objc2-core-foundation only.

Returns an array of all focus items within this container that intersect with the provided rect. rect is expressed in coordinateSpace. Note: starting in iOS & tvOS 16.0, UIView will return its subviews from this method. If you override this method in a UIView subclass, it will be your responsibility to call super and merge your array of custom focus items with UIView’s default focus items.

impl UIResponderStandardEditActions for UIDatePicker
