//! iOS support

//!
|
|
//! # Building app
|
|
//! To build ios app you will need rustc built for this targets:
|
|
//!
|
|
//! - armv7-apple-ios
|
|
//! - armv7s-apple-ios
|
|
//! - i386-apple-ios
|
|
//! - aarch64-apple-ios
|
|
//! - x86_64-apple-ios
|
|
//!
|
|
//! Then
|
|
//!
|
|
//! ```
|
|
//! cargo build --target=...
|
|
//! ```
|
|
//! The simplest way to integrate your app into xcode environment is to build it
|
|
//! as a static library. Wrap your main function and export it.
|
|
//!
|
|
//! ```rust, ignore
|
|
//! #[no_mangle]
|
|
//! pub extern fn start_winit_app() {
|
|
//! start_inner()
|
|
//! }
|
|
//!
|
|
//! fn start_inner() {
|
|
//! ...
|
|
//! }
|
|
//! ```
|
|
//!
|
|
//! Compile project and then drag resulting .a into Xcode project. Add winit.h to xcode.
|
|
//!
|
|
//! ```ignore
|
|
//! void start_winit_app();
|
|
//! ```
|
|
//!
|
|
//! Use start_winit_app inside your xcode's main function.
|
|
//!
|
|
//!
|
|
//! # App lifecycle and events
|
|
//!
|
|
//! iOS environment is very different from other platforms and you must be very
|
|
//! careful with it's events. Familiarize yourself with
|
|
//! [app lifecycle](https://developer.apple.com/library/ios/documentation/UIKit/Reference/UIApplicationDelegate_Protocol/).
|
|
//!
|
|
//!
|
|
//! This is how those event are represented in winit:
|
|
//!
|
|
//! - applicationDidBecomeActive is Resumed
|
|
//! - applicationWillResignActive is Suspended
|
|
//! - applicationWillTerminate is LoopExiting
|
|
//!
|
|
//! Keep in mind that after LoopExiting event is received every attempt to draw with
|
|
//! opengl will result in segfault.
|
|
//!
|
|
//! Also note that app may not receive the LoopExiting event if suspended; it might be SIGKILL'ed.
