Bmob Database — iOS Native SDK
iOS SDK 名为 BmobSDK，是 Objective-C 编写的 framework，Swift 项目通过 Bridging Header 桥接使用。SDK 数据模型以 BmobObject 为核心，不需要为每个表写子类（与 Android 不同）。
核心原则
1. 安装 SDK — 强推 CocoaPods：
target "你的项目名称" do
platform :ios, "15.6"
use_frameworks!
pod 'BmobSDK'
end
pod install
装完后只打开 .xcworkspace，不要再打开 .xcodeproj，否则找不到 Pod 引入的库。
也可手动导入 BmobSDK.xcframework，并链接以下系统库（详见 references/install.md）。
2. Swift 必须桥接： 新建任意 .m 文件让 Xcode 弹"Create Bridging Header"，然后在生成的 项目名-Bridging-Header.h 加：
#import <BmobSDK/Bmob.h>
3. 初始化（OC） — AppDelegate.m：
- (BOOL)application:(UIApplication *)application
didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
[Bmob registerWithAppKey:@"你的Application ID"];
return YES;
}
3. 初始化（Swift / SwiftUI） — AppApp.swift：
@main
struct MyApp: App {
init() {
Bmob.register(withAppKey: "你的Application ID")
}
var body: some Scene { WindowGroup { ContentView() } }
}
4. 域名重置（上线必做）： 工信部要求正式上线必须用备案域名：
Bmob.resetDomain("https://sdk.yourapp.com")
Bmob.register(withAppKey: "...")
OC 端用 [Bmob resetDomain:@"https://sdk.yourapp.com"];。
5. 不要硬编码 Master Key 到 App bundle。客户端只用 Application ID（必要时配 Secret Key + 加密授权）。

反模式
见 shared/anti-patterns.md。本端重点：勿 commit 真实 AppKey；ATS 尽量 HTTPS。
单条 CRUD（Swift 现代写法）
添加
let gameScore = BmobObject(className: "GameScore")
gameScore.setObject("John Smith", forKey: "playerName")
gameScore.setObject(90, forKey: "score")
gameScore.setObject(false, forKey: "cheatMode")
gameScore.saveInBackground { (isSuccessful, error) in
if let error = error {
print("保存失败: \(error.localizedDescription)")
} else {
print("保存成功: \(gameScore.objectId ?? "")")
}
}
查询单条
let bquery = BmobQuery(className: "GameScore")
bquery.getObjectInBackground(withId: "0c6db13c") { (object, error) in
if let error = error { print(error); return }
guard let object = object else { return }
let playerName = object.object(forKey: "playerName") as? String
let score = object.object(forKey: "score") as? NSNumber
print(playerName ?? "", score ?? 0)
}
更新（按 objectId）
let gameScore = BmobObject(outDatatWithClassName: "GameScore", objectId: "0c6db13c")
gameScore.setObject(91, forKey: "score")
gameScore.updateInBackground { (isSuccessful, error) in
if let error = error { print(error) }
}
注意 API 名称是 outDatatWithClassName（拼写历史遗留，不要改）——用这个方法获取的 BmobObject 不会先发 GET 查询，直接拿来 update / delete。
删除
let gameScore = BmobObject(outDatatWithClassName: "GameScore", objectId: "0c6db13c")
gameScore.deleteInBackground { (isSuccessful, error) in }
查询列表（带条件 + 排序 + 分页）
let query = BmobQuery(className: "GameScore")
query.whereKey("score", greaterThan: 100)
query.orderByDescending("createdAt")
query.limit = 20
query.skip = 0
query.findObjectsInBackground { (array, error) in
guard let results = array as? [BmobObject] else { return }
for obj in results {
print(obj.objectId ?? "", obj.object(forKey: "playerName") ?? "")
}
}
单条 CRUD（Objective-C）
BmobObject *gameScore = [BmobObject objectWithClassName:@"GameScore"];
[gameScore setObject:@"小明" forKey:@"playerName"];
[gameScore setObject:@78 forKey:@"score"];
[gameScore setObject:[NSNumber numberWithBool:YES] forKey:@"cheatMode"];
[gameScore saveInBackgroundWithResultBlock:^(BOOL isSuccessful, NSError *error) {
}];
BmobQuery *bquery = [BmobQuery queryWithClassName:@"GameScore"];
[bquery getObjectInBackgroundWithId:@"0c6db13c"
block:^(BmobObject *object, NSError *error) {
if (object) {
NSString *playerName = [object objectForKey:@"playerName"];
BOOL cheat = [[object objectForKey:@"cheatMode"] boolValue];
NSLog(@"%@ %d", playerName, cheat);
}
}];
BmobObject *gs = [BmobObject objectWithoutDatatWithClassName:@"GameScore" objectId:@"0c6db13c"];
[gs setObject:@91 forKey:@"score"];
[gs updateInBackground];
BmobObject *gs = [BmobObject objectWithoutDatatWithClassName:@"GameScore" objectId:@"0c6db13c"];
[gs deleteInBackground];
与 MCP 联动
如已配置 Bmob MCP，先 get_project_tables 拿真实 schema，避免：
- 字段名拼错（
setObject:forKey: 不校验 schema）
- BmobObject 与 BmobUser 混用
排错速查
跨平台现象先查 shared/faq.md。
| 现象 | 排查 |
|---|
| 100 报错 | 请求内容（查询条件）有误 |
| 20003 none objectid | 更新 / 删除 / 查询单条没传 objectId |
| 20004 none object | 查询结果为空 |
| 20006 cloud function failed | 云函数执行报错 |
| 20017 init not finish | 在 register 完成前调用了 SDK；检查 init {} 顺序 |
| Swift "use of undeclared identifier 'BmobObject'" | Bridging Header 没建或没 #import <BmobSDK/Bmob.h> |
| Xcode 14+ 找不到 Pod 库 | 打开了 .xcodeproj 而不是 .xcworkspace |
| App Store 审核拒 ATS | 备案域名换 HTTPS，移除 NSAllowsArbitraryLoads |
| release 包请求被拒 / 403 | 没配 SDK 类型备案域名；或 resetDomain 调用顺序错（必须在 register 前） |
