Functions ¶

func AddMethod ¶

func AddMethod(cls Class, sel SEL, impl any, types string) bool

AddMethod adds a new method to a class. impl must be a uintptr from purego.NewCallback.

func Dlopen ¶

func Dlopen(path string, mode int) (uintptr, error)

Dlopen loads a dynamic library.

func GoString ¶

func GoString(nsstr ID) string

GoString converts an NSString to a Go string.

func NewCallback ¶

func NewCallback(fn any) uintptr

NewCallback creates a Go callback for C.

func RegisterClassPair ¶

func RegisterClassPair(cls Class)

RegisterClassPair registers a class pair with the runtime.

func Send ¶

func Send[T any](id ID, sel SEL, args ...any) T

Send calls objc_msgSend with the given arguments.

Types ¶

type Block ¶

type Block = purego.Block

Type aliases from purego/objc

func NewBlock ¶

func NewBlock(fn any) Block

NewBlock creates an Objective-C block from a Go function. The Go function must take a Block as its first argument. Use Block.Release() to free the block when done.

type Class ¶

type Class = purego.Class

Type aliases from purego/objc

func AllocateClassPair ¶

func AllocateClassPair(super Class, name string, extraBytes int) Class

AllocateClassPair calls objc_allocateClassPair.

func GetClass ¶

func GetClass(name string) Class

GetClass returns the Objective-C class with the given name.

type ID ¶

type ID = purego.ID

Type aliases from purego/objc

func NSString ¶

func NSString(s string) ID

NSString converts a Go string to an NSString object.

type Protocol ¶

type Protocol = purego.Protocol

Type aliases from purego/objc

type SEL ¶

type SEL = purego.SEL

Type aliases from purego/objc

func Sel ¶

func Sel(name string) SEL

Sel returns a cached selector for the given name.
