Implementations§

Source §

impl TKSmartCardUserInteractionForSecurePINVerification

Methods declared on superclass NSObject.

Source

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

Source

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

Methods from Deref<Target = TKSmartCardUserInteractionForPINOperation>§

Source

pub unsafe fn PINCompletion(&self) -> TKSmartCardPINCompletion

Bitmask specifying condition(s) under which PIN entry should be considered complete.

Note: Default value: TKSmartCardPINCompletionKey

Source

pub unsafe fn setPINCompletion(&self, pin_completion: TKSmartCardPINCompletion)

Setter for PINCompletion.

Source

pub unsafe fn PINMessageIndices(&self) -> Option<Retained<NSArray<NSNumber>>>

List of message indices referring to a predefined message table. It is used to specify the type and number of messages displayed during the PIN operation.

If nil, the reader does not display any message (reader specific). Typically, PIN verification takes 1 message, PIN modification 1-3 messages.

Note: Default value: nil

Source

pub unsafe fn setPINMessageIndices( &self, pin_message_indices: Option<&NSArray<NSNumber>>, )

Setter for PINMessageIndices.

Source

pub unsafe fn locale(&self) -> Option<Retained<NSLocale>>

Locale defining the language of displayed messages. If set to nil, the user’s current locale is used.

Note: Default value: the user’s current locale

Source

pub unsafe fn setLocale(&self, locale: Option<&NSLocale>)

Setter for locale.

Source

pub unsafe fn resultSW(&self) -> u16

SW1SW2 result code.

Source

pub unsafe fn setResultSW(&self, result_sw: u16)

Setter for resultSW.

Source

pub unsafe fn resultData(&self) -> Option<Retained<NSData>>

Optional block of returned data (without SW1SW2 bytes).

Source

pub unsafe fn setResultData(&self, result_data: Option<&NSData>)

Setter for resultData.

Methods from Deref<Target = TKSmartCardUserInteraction>§

Source

pub unsafe fn delegate( &self, ) -> Option<Retained<ProtocolObject<dyn TKSmartCardUserInteractionDelegate>>>

Delegate for state observing of the interaction.

Source

pub unsafe fn setDelegate( &self, delegate: Option<&ProtocolObject<dyn TKSmartCardUserInteractionDelegate>>, )

This is a weak property. Setter for delegate.

Source

pub unsafe fn initialTimeout(&self) -> NSTimeInterval

Initial interaction timeout. If set to 0, the reader-defined default timeout is used.

Note: Default value: 0

Source

pub unsafe fn setInitialTimeout(&self, initial_timeout: NSTimeInterval)

Setter for initialTimeout.

Source

pub unsafe fn interactionTimeout(&self) -> NSTimeInterval

Timeout after the first key stroke. If set to 0, the reader-defined default timeout is used.

Note: Default value: 0

Source

pub unsafe fn setInteractionTimeout(&self, interaction_timeout: NSTimeInterval)

Setter for interactionTimeout.

Source

pub unsafe fn runWithReply(&self, reply: &DynBlock<dyn Fn(Bool, *mut NSError)>)

Available on crate feature block2 only.

Runs the interaction.

Source

pub unsafe fn cancel(&self) -> bool

Attempts to cancel a running interaction. Note that for some interactions, this functionality might not be available.

Returns: Returns NO if the operation is not running, or cancelling is not supported.

Methods from Deref<Target = NSObject>§

Source

pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !

Handle messages the object doesn’t recognize.

See Apple’s documentation for details.

Methods from Deref<Target = AnyObject>§

Source

pub fn class(&self) -> &'static AnyClass

Available on crate feature TKToken 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());

Source

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 TKToken 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.

Source

pub fn downcast_ref<T>(&self) -> Option<&T>
where T: DowncastTarget,

Available on crate feature TKToken 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`
    }
}
