## 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
