Struct SKTileMapNode 

pub struct SKTileMapNode { /* private fields */ }

Available on crate feature SKNode and crate feature SKTileMapNode and crate feature objc2-app-kit and macOS only.

A SpriteKit node used to render a 2D array of textured sprites. Uses SKTileSet to determine what textures it can use to render. Separate tile map nodes can be layered on top of one another to achieve various effects, such as parallax scrolling.

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

Create a tile map node with the specified tile set and dimensions. The tiles of the map will be empty, equivalent to the nil tile definition/group.

Parameter tileSet: the tile set that is used to render the tiles

Parameter columns: the number of columns in the map that can hold tiles

Parameter rows: the number of rows in the map that can hold tiles

Parameter tileSize: the size of each tile in points

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

Create a tile map node with the specified tile set and dimensions, and fill it with the specified tile group.

Parameter tileSet: the tile set that is used to render the tiles

Parameter columns: the number of columns in the map that can hold tiles

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

Create a tile map node with the specified tile set and dimensions, and fill it with a specific layout of tile groups that belong to the provided tile set. The tileGroupLayout array should match the dimensions of the tile map (i.e., the number of elements should be equal to columns * rows). Index 0 of the array maps to column 0, row 0 of the tile map. Index 1 is column 1, row 0, and so on, wrapping around to the next row once the index passes the number of columns in the tile map. If the array has fewer elements than the number of tiles in the map, the remaining tiles are initialized with the nil tile group. If the array has more elements than the number of tiles in the map, the extra tile groups are ignored.

pub fn pressureChangeWithEvent(&self, event: &NSEvent)

pub fn contextMenuKeyDown(&self, event: &NSEvent)

Handle a key event that should present a context menu at the user focus.

Most applications should not override this method. Instead, you should customize the context menu displayed from a keyboard event by implementing menuForEvent: and selectionAnchorRect, or showContextMenuForSelection:, rather than this method.

You should only override this method when you do not want the system-provided default behavior for the context menu hotkey, either for a specific key combination, or for the hotkey in general. For example, if your application already provides a different behavior for control-Return (the default context menu hotkey definition), and you want to preserve that behavior, you should override this method to handle that specific key combination, and then return without calling super. Note that the user may customize the hotkey to a different key combination, so in this example, if any other key combination is passed to your method, you would call super.

An implementation of this method should call [super contextMenuKeyDown:event] to pass the request up the responder chain. If the message reaches the application object, NSApplication’s implementation of this method will send showContextMenuForSelection: to the responder chain. If you do not call super, then no further handling of the key event will be performed.

Note: In some cases, showContextMenuForSelection: will be called without a prior call to contextMenuKeyDown:. This occurs when a view receives an Accessibility ShowMenu action, or when the user has created a Cocoa Text key binding to map a different key combination to the showContextMenuForSelection: action.

Parameter event: The key down event that matches the system-wide context menu hotkey combination.

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`
    }
}
