将 AppDelegate 按业务拆成多个子服务（SOA），通过消息转发统一调度 UIApplicationDelegate 回调。
- iOS 12.0+（库逻辑不变；12.0 为当前 Xcode 构建 Swift 模块所需）
- Objective-C 或 Swift 5.0+
通过 CocoaPods 集成。Swift 工程建议使用 use_frameworks! 以便 import ZKAppDelegateSOA：
platform :ios, '12.0'
use_frameworks!
target 'YourApp' do
pod 'ZKAppDelegateSOA', :git => 'https://github.com/kaiser143/ZKAppDelegateSOA.git', :tag => '0.1.2'
end子服务需实现 ZKService（即 UIApplicationDelegate），并在 +load 中注册：
#import <ZKAppDelegateSOA/ZKAppDelegateSOA.h>
@interface ZKPushAppDelegateService : NSObject <ZKService>
@end
@implementation ZKPushAppDelegateService
+ (void)load {
[[ZKAppDelegateSOA sharedInstance] registerServiceWithClass:self];
}
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 推送、统计等初始化
return YES;
}
@end在 AppDelegate 的生命周期方法里调用 ZKAppDelegateSOA，未实现的方法可通过 forwardInvocation: 转发（见 Example 工程）：
#import <ZKAppDelegateSOA/ZKAppDelegateSOA.h>
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[[ZKAppDelegateSOA sharedInstance] application:application
didFinishLaunchingWithOptions:launchOptions];
return YES;
}
- (void)forwardInvocation:(NSInvocation *)invocation {
if (invocation.target == [ZKAppDelegateSOA sharedInstance]) {
[[ZKAppDelegateSOA sharedInstance] forwardInvocation:invocation];
return;
}
[super forwardInvocation:invocation];
}import UIKit
import ZKAppDelegateSOA无需手写 Bridging Header（CocoaPods + use_frameworks! 即可）。
子服务必须继承 NSObject 并遵循 ZKService，且需加 @objc 以便运行时注册：
import UIKit
import ZKAppDelegateSOA
@objc(ZKPushAppDelegateService)
final class ZKPushAppDelegateService: NSObject, ZKService {
// 等价于 ObjC 的 +load 注册
private static let registerOnLoad = ZKAppDelegateSOARegistration.onLoad(ZKPushAppDelegateService.self)
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]? = nil
) -> Bool {
_ = Self.registerOnLoad
return true
}
}也可在 AppDelegate 启动时手动注册：
ZKAppDelegateSOA.shared.register(ZKPushAppDelegateService.self)AppDelegate 建议继承 NSObject（或 UIResponder + 显式 @objc 方法），在对应回调中交给 SOA：
import UIKit
import ZKAppDelegateSOA
@main
class AppDelegate: NSObject, UIApplicationDelegate {
func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
_ = ZKAppDelegateSOA.shared.application(application, didFinishLaunchingWithOptions: launchOptions)
return true
}
}其他 UIApplicationDelegate 方法同样在 AppDelegate 中显式调用 ZKAppDelegateSOA.shared 的对应方法，或通过 forwardInvocation 转发（与 Objective-C Example 相同）。
