## 安装

### Swift Package Manager（推荐）

在 Xcode → File → Add Package Dependencies 中输入：

```
https://github.com/xuqm/XuqmGroup-iOSSDK
```

或在 `Package.swift` 中添加：

```swift
dependencies: [
    .package(url: "https://github.com/xuqm/XuqmGroup-iOSSDK", from: "0.1.0")
]
```

按需引入所需模块：

```swift
.target(
    name: "MyApp",
    dependencies: [
        .product(name: "XuqmCore",   package: "XuqmGroup-iOSSDK"),
        .product(name: "XuqmIM",     package: "XuqmGroup-iOSSDK"),
        .product(name: "XuqmUpdate", package: "XuqmGroup-iOSSDK"),
    ]
)
```

## 快速接入

### 1. 初始化

在 `AppDelegate.application(_:didFinishLaunchingWithOptions:)` 中：

```swift
import XuqmCore

XuqmSDK.shared.initialize(
    appKey:     "your_app_id",
    appSecret:  "your_app_secret",
    apiBaseUrl: "https://sentry.xuqinmin.com",
    imWsUrl:    "wss://sentry.xuqinmin.com/ws/im",
    debug:      false
)
```

### 2. IM 登录与监听消息

```swift
import XuqmIM

// 登录（appId 已在 init 时指定）
try await ImSDK.shared.login(userId: "user_001", nickname: "张三")

// 监听事件
ImSDK.shared.addListener(self)

extension ViewController: ImEventListener {
    func onConnected() { print("WS connected") }
    func onMessage(_ msg: ImMessage) { /* 处理消息 */ }
    func onDisconnected(reason: String?) { /* 断线 */ }
}
```

### 3. 发送消息

```swift
// 发文本
let sent = try await ImSDK.shared.sendMessage(
    toId:     "user_002",
    chatType: .single,
    msgType:  .text,
    content:  "Hello!"
)

// 发图片（content 为 JSON 字符串）
let imgContent = try JSONSerialization.data(withJSONObject: [
    "url": "https://cdn.example.com/img.jpg",
    "width": 800, "height": 600
])
let sent = try await ImSDK.shared.sendMessage(
    toId: "user_002", chatType: .single,
    msgType: .image, content: String(data: imgContent, encoding: .utf8)!
)
```

### 4. 撤回消息

```swift
let revoked = try await ImSDK.shared.revokeMessage(messageId: msg.id)
```

### 5. 群聊

```swift
// 创建群组
let group = try await ImSDK.shared.createGroup(name: "我的群", memberIds: ["user_001", "user_002"])

// 订阅群消息
ImSDK.shared.subscribeGroup(groupId: group.id)

// 发送群消息
try await ImSDK.shared.sendMessage(
    toId: group.id, chatType: .group, msgType: .text, content: "大家好"
)
```

### 6. 检查更新

```swift
import XuqmUpdate

// App 整包更新
let appInfo = try await UpdateSDK.shared.checkAppUpdate(currentVersionCode: 1)
if let info = appInfo, info.forceUpdate {
    // 强制更新：跳转 App Store 或下载链接
    UIApplication.shared.open(URL(string: info.downloadUrl ?? info.appStoreUrl!)!)
}

// RN Bundle 热更新
let bundle = try await UpdateSDK.shared.checkRNUpdate(moduleId: "home", currentVersion: "1.0.0")
if let bundle = bundle {
    let data = try await UpdateSDK.shared.downloadBundle(url: bundle.downloadUrl)
    // 缓存至本地，下次启动时由 BundleRuntime 加载
}
```
