## AppleScriptObjC Cheatsheet: Objective-C Interoperability

### Overview

AppleScriptObjC is a powerful framework that allows developers to write AppleScript code using Objective-C syntax. One of the key benefits of AppleScriptObjC is its ability to easily interoperate with Objective-C code. This cheatsheet focuses on the Objective-C interoperability features of AppleScriptObjC.

### Declaring Variables

#### Declaring Objective-C Variables

set myArray to current application's NSMutableArray's arrayWithObjects:"Hello", "World"

### Calling Objective-C Methods

#### Calling Objective-C Methods on Objects

set myArray to current application's NSMutableArray's arrayWithObjects:"Hello", "World"

set objectCount to myArray's count()

#### Calling Objective-C Class Methods

set myArray to current application's NSMutableArray's arrayWithObjects:"Hello", "World"

set newArray to current application's NSMutableArray's arrayWithArray:myArray

### Working with Objective-C Objects

#### Creating Objective-C Objects

set myArray to current application's NSMutableArray's alloc()

set myArray to myArray's initWithCapacity:10

#### Releasing Objective-C Objects

set myArray to current application's NSMutableArray's arrayWithObjects:"Hello", "World"

set myArray to missing value

### Working with Objective-C Properties

#### Getting Objective-C Property Values

set myWindow to current application's NSApplication's sharedApplication()'s mainWindow()

set windowTitle to myWindow's title()

#### Setting Objective-C Property Values

set myWindow to current application's NSApplication's sharedApplication()'s mainWindow()

myWindow's setTitle:"My Window Title"

### Working with Objective-C Constants

#### Getting Objective-C Constants

set myConstant to current application's NSApplication's NSAppKitVersionNumber
