iOS Platform

Complete iOS SDK framework declarations providing access to all iOS frameworks, native memory management utilities, and Objective-C runtime integration. Covers 139 iOS frameworks from ARKit to WebKit.

Capabilities

iOS Entry Point

Single entry point providing access to all iOS SDK frameworks and runtime functions.

/// <reference path="./node_modules/tns-platform-declarations/ios.d.ts" />

Core iOS Runtime Functions

Essential runtime functions for iOS development and native object management.

/**  
 * Trigger garbage collection in JavaScript
 */
declare function __collect(): void;

/**
 * Release the reference to the wrapped native Objective-C object
 * @param object - The Objective-C object to release
 */
declare function __releaseNativeCounterpart(object: NSObject): void;

/**
 * Get accurate system timestamp in milliseconds
 * @returns Current system time in milliseconds
 */
declare function __time(): Number;

Usage Examples:

// Create and manage NSObject instances
const nsString = new NSString("Hello iOS");
// ... use the object
__releaseNativeCounterpart(nsString); // Release when done

// Get high-precision timestamp
const timestamp = __time();
console.log(`Current time: ${timestamp}`);

// Trigger garbage collection
__collect();

iOS Framework Declarations

Memory Management

iOS platform declarations support both manual and automatic memory management:

// Manual memory management
const nsObject = NSObject.alloc().init();
try {
  // Use the object...
} finally {
  __releaseNativeCounterpart(nsObject);
}

// Automatic memory management (recommended)  
const autoString = NSString.stringWithString("Auto-managed");
// No manual release needed

// Garbage collection
__collect();

Framework Usage Patterns

Foundation Framework Usage

// String operations
const str = NSString.stringWithString("Hello");
const uppercaseStr = str.uppercaseString;

// Array operations
const array = NSMutableArray.alloc().init();
array.addObject("Item 1");
array.addObject("Item 2");

// Dictionary operations
const dict = NSMutableDictionary.alloc().init();
dict.setObjectForKey("value", "key");

UIKit Framework Usage

// View controller
const viewController = UIViewController.alloc().init();
viewController.title = "My View";

// Alert controller
const alert = UIAlertController.alertControllerWithTitleMessagePreferredStyle(
  "Title",
  "Message", 
  UIAlertControllerStyle.Alert
);

// Add alert action
const action = UIAlertAction.actionWithTitleStyleHandler(
  "OK",
  UIAlertActionStyle.Default,
  null
);
alert.addAction(action);

Performance Considerations

• Framework Loading: Only frameworks referenced in code are loaded
• Memory Usage: iOS declarations are comprehensive and memory-intensive
• Compilation Time: Large number of frameworks can slow TypeScript compilation
• Runtime Performance: Native calls have minimal overhead through NativeScript runtime
