impl NSURL

👎Deprecated: Use NSURLComponents instead, which lets you create a valid URL with any valid combination of URL components and subcomponents (not just scheme, host and path), and lets you set components and subcomponents with either percent-encoded or un-percent-encoded strings.

Available on crate feature std and Unix and non-crate feature gnustep-1-7 only.

pub fn from_file_path<P: AsRef<Path>>(path: P) -> Option<Retained<Self>>

Available on crate feature std and Unix and non-crate feature gnustep-1-7 only.

Create a file url from a Path.

If the path is relative, it will be considered relative to the current directory.

Returns None when given an invalid path (such as a path containing interior NUL bytes). The exact checks are not guaranteed.

Non-unicode and HFS+ support

Modern Apple disk drives use APFS nowadays, which forces all paths to be valid unicode. The URL standard also uses unicode, and non-unicode parts of the URL will be percent-encoded, and the url will be given the scheme file://. All of this is as it should be.

Unfortunately, a lot of Foundation APIs (including the NSFileManager and NSData APIs) currently assume that they can always get unicode paths back by calling NSURL::path internally, which is not true.

If you need to support non-unicode paths in HFS+ with these APIs, you can work around this issue by percent-encoding any non-unicode parts of the path yourself beforehand, similar to what’s done in the trash-rs crate. (this function cannot do that for you, since it relies on a quirk of HFS+ that b“\xf8“ and b“%F8“ refer to the same file).

Examples

use std::path::Path;
use objc2_foundation::NSURL;

// Absolute paths work as you'd expect.
let url = NSURL::from_file_path("/tmp/file.txt").unwrap();
assert_eq!(url.to_file_path().unwrap(), Path::new("/tmp/file.txt"));

// Relative paths are relative to the current directory.
let url = NSURL::from_file_path("foo.txt").unwrap();
assert_eq!(url.to_file_path().unwrap(), std::env::current_dir().unwrap().join("foo.txt"));

// Some invalid paths return `None`.
assert!(NSURL::from_file_path("").is_none());
// Another example of an invalid path containing interior NUL bytes.
assert!(NSURL::from_file_path("/a/\0a").is_none());

pub fn from_directory_path<P: AsRef<Path>>(path: P) -> Option<Retained<Self>>

Available on crate feature std and Unix and non-crate feature gnustep-1-7 only.

Create a directory url from a Path.

This differs from from_file_path in that the path is treated as a directory, which means that other normalization rules are applied to it (to make it end with a /).

Examples

use std::path::Path;
use objc2_foundation::NSURL;

// Directory paths get trailing slashes appended
let url = NSURL::from_directory_path("/Library").unwrap();
assert_eq!(url.to_file_path().unwrap(), Path::new("/Library/"));

// Unless they already have them.
let url = NSURL::from_directory_path("/Library/").unwrap();
assert_eq!(url.to_file_path().unwrap(), Path::new("/Library/"));

// Similarly for relative paths.
let url = NSURL::from_directory_path("foo").unwrap();
assert_eq!(url.to_file_path().unwrap(), std::env::current_dir().unwrap().join("foo/"));

// Various dots may be stripped.
let url = NSURL::from_directory_path("/Library/././.").unwrap();
assert_eq!(url.to_file_path().unwrap(), Path::new("/Library/"));

// Though of course not if they have semantic meaning.
let url = NSURL::from_directory_path("/Library/..").unwrap();
assert_eq!(url.to_file_path().unwrap(), Path::new("/Library/.."));

pub fn to_file_path(&self) -> Option<PathBuf>

Available on crate feature std and Unix and non-crate feature gnustep-1-7 only.

Extract the path part of the URL as a PathBuf.

This will return a path regardless of isFileURL. It is the responsibility of the caller to ensure that the URL is valid to use as a file URL.

Compatibility note

This currently does not work for non-unicode paths (which are fairly rare on macOS since HFS+ was been superseded by APFS).

This also currently always returns absolute paths (it converts relative URL paths to absolute), but that may change in the future.

Examples

use std::path::Path;
use objc2_foundation::{NSURL, NSString};

let url = unsafe { NSURL::URLWithString(&NSString::from_str("file:///tmp/foo.txt")).unwrap() };
assert_eq!(url.to_file_path().unwrap(), Path::new("/tmp/foo.txt"));

See also the examples in from_file_path.

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`
    }
}
