Implementations

impl<ObjectType: Message> NSEnumerator<ObjectType>

pub fn nextObject(&mut self) -> Option<Id<ObjectType>>

impl<ObjectType: Message> NSEnumerator<ObjectType>

Methods declared on superclass NSObject

pub unsafe fn init(this: Allocated<Self>) -> Id<Self>

pub unsafe fn new() -> Id<Self>

impl<ObjectType: Message> NSEnumerator<ObjectType>

NSExtendedEnumerator

pub fn allObjects(&self) -> Id<NSArray<ObjectType>>

Available on crate feature NSArray only.

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.

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 unsafe fn get_mut_ivar<T>(&mut self, name: &str) -> &mut T

where T: Encode,

👎Deprecated: this is difficult to use correctly, use Ivar::load_mut instead.

Use Ivar::load_mut 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.
