Indicates the percentage of content cataloging completed on the device. Its value ranges from 0 to 100.

pub unsafe fn contents(&self) -> Option<Retained<NSArray<ICCameraItem>>>

Available on crate feature ICCameraItem only.

Contents of the camera. The structure of the elements in this array will reflect the folder structure of the storage reported by the camera. Each item in this array will correspond to a storage on the camera.

pub unsafe fn mediaFiles(&self) -> Option<Retained<NSArray<ICCameraItem>>>

Available on crate feature ICCameraItem only.

The property mediaFiles represents all image, movie and audio files on the camera. These files are returned as a single array without regard to the folder hierarchy used to store these files on the camera.

pub unsafe fn isEjectable(&self) -> bool

Indicates whether the device can be ‘soft’ removed or disconnected.

pub unsafe fn isLocked(&self) -> bool

pub unsafe fn mediaPresentation(&self) -> ICMediaPresentation

The media presentation describes the visible assets from a device that may contain multiple formats of each media asset. The asigngments are of the type ICMediaPresentation enumeration. This property is available only if the capability ICCameraDeviceSupportsHEIF is present.

A device supporting this capability can specify the following presentations:

ICMediaPresentationConverted - The default behavior for applications retrieving images from a device supporting HEIF is to show only converted JPG from HEIF originals, and only H264 encoded video assets from HEVC. ICMediaPresentationOriginal - This presentation will show only original images from a device supporting HEIF and HEVC. Burned in renders are always exported in JPG, as are burned in effects for MOV clips.

The deleteFailed block will return:

• NSDictionary <ICDeleteError , ICCameraItem*>*

The completion block will return: — error:

• nil if successful

• NSError* with an code set to ICReturnDeleteFilesFailed if any file failed.

• result: NSDictionary <ICDeleteResult , NSArray <ICCameraItem >>* result

• ICDeleteSuccessful: NSArray <ICCameraItem > success

• ICDeleteFailed: NSArray <ICCameraItem > failed

Cancels the current delete operation started by sending a ‘requestDeleteFiles:’. This will only cancel operations in flight when a batch of files have been requested for deletion.

pub unsafe fn requestSyncClock(&self)

Upload a file at fileURL to the camera. The options dictionary is not used in this version.

The uploadDelegate passed must not be nil. When this request is completed, the didUploadSelector of the uploadDelegate object is called. The didUploadSelector should have the same signature as: - (void)didUploadFile:(NSURL*)fileURL error:(NSError*)error contextInfo:(void*)contextInfo. The content of error returned should be examined to determine if the request completed successfully.

pub unsafe fn ptpEventHandler( &self, ) -> NonNull<DynBlock<dyn Fn(NonNull<NSData>)>>

Available on crate feature block2 only.

As an alternative to setting up an object to handle PTP event packets, a handler can be set. The handler will always be called in place of the delegate if non-nil. If the handler is not present, the delegate will be called if present. It is guaranteed only one of the methods will be called if both are implemented.

This should be sent only if the ‘capabilities’ property contains ‘ICCameraDeviceCanAcceptPTPCommands’. All PTP cameras have this capability. The response to this command will be delivered using didSendCommandSelector of sendCommandDelegate. The didSendCommandSelector should have the same signature as: - (void)didSendPTPCommand:(NSData*)command inData:(NSData*)data response:(NSData*)response error:(NSError*)error contextInfo:(void*)contextInfo. The content of error returned should be examined to determine if the request completed successfully.

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`
    }
}
