func RegisterClass ¶
func RegisterClass(class Class)
RegisterClass registers a Class with the Objective-C runtime.
func RegisterSelector ¶
Types ¶
type Class ¶
type Class interface { Object // AddMethod registers a Go function to be called whenever // an instance of the class receives a message for the given // selector. // // The AddMethod call only works for classes created with // objc.NewClass. Method calls will only be received by the // Go function if instances of the class are instanciated // by calling objc.NewGoInstance. AddMethod(selector string, fn interface{}) // Swizzle swaps the implementation of two methods on a class // so that messages sent to selectorA are received by the // implementation of selectorB and vice-versa. Swizzle(selectorA, selectorB string) }
A Class represents a special Objective-C class Object.
func NewClassFromStruct ¶
func NewClassFromStruct(value interface{}) Class
NewClass returns a new class. The value parameter must point to a value of the struct that is used to represent instances of the class in Go.
type Object ¶
type Object interface { // SendMsg sends an arbitrary message to the method on the // object that is idenfieid by selectorName. Send(selector string, args ...interface{}) Object // SendSuperMsg is like SendMsg, but sends to the object's // super class instead. SendSuper(selector string, args ...interface{}) Object // Class returns the the special class object corresponding // to this object. Class() Class // Alloc sends the "alloc" message to the object. Alloc() Object // Init sends the "init" message to the object. Init() Object // Retain sends the "retain" message to the object. Retain() Object // Release sends the "release" message to the object. Release() Object // AutoRelease sends the "autorelease" message to the object. Autorelease() Object // Copy sends the "copy" message to the object. Copy() Object Equals(o Object) bool // String returns a string-representation of the object. // This is equivalent to sending the "description" // message to the object, except that this method // returns a Go string. String() string // Pointer returns the in-memory address of the object. Pointer() uintptr // Uint returns the value of the object as an uint64. Uint() uint64 // Int returns the value of the object as an int64. Int() int64 // Float returns the value of the object as a float64. Float() float64 // Bool returns the value of the object as a bool. Bool() bool Set(setter string, args ...interface{}) Get(getter string) Object GetSt(getter string, ret interface{}) }
An Object represents an Objective-C object, along with some convenience methods only found on NSObjects.
type Selector ¶
type Selector interface { // Selector returns a string representation of // a selector. Selector() string // String returns the same string as Selector does. // It is only implemented to implement the Stringer // interface. String() string }
A Selector represents an Objective-C method selector.
