bmob-database-ios

Use when implementing Bmob NoSQL database CRUD in an iOS native project — both Objective-C and Swift / SwiftUI / UIKit. Triggers: BmobSDK, BmobSDK.xcframework, pod 'BmobSDK', #import <BmobSDK/Bmob.h>, Bmob registerWithAppKey, [Bmob register(withAppKey:)], BmobObject objectWithClassName, BmobQuery queryWithClassName, BmobUser, BmobInstallation, BmobFile, BmobGeoPoint, BmobRelation, saveInBackgroundWithResultBlock, getObjectInBackgroundWithId, findObjectsInBackground, Bridging-Header.h. NOT for cross-platform JavaScript / WeChat Mini Program (use bmob-database-javascript), Android (use bmob-database-android), or any other language via REST (use bmob-database-restful). If Bmob MCP is configured, call get_project_tables via bmob-mcp before writing code.

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

# Podfile
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 {
    // release 上线时启用备案域名,必须在 registerWithAppKey 之前
    // [Bmob resetDomain:@"https://你的备案域名"];
    [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")    // 必须在 register 前
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)。

安全清单

  • [ ] release 关闭调试输出:测试期 [Bmob setDebug:YES],上架前删掉。
  • [ ] App Transport Security(ATS):如果备案域名是 HTTP(不推荐),需要在 Info.plistNSAppTransportSecurity → NSAllowsArbitraryLoads = YES,但 App Store 审核可能拒;尽量用 HTTPS。
  • [ ] 写入的表必须配 ACL:否则任意用户可改任意行。
  • [ ] Bridging Header 不要 commit 真实 AppKey:用配置文件 / xcconfig / environment 注入。
  • [ ] release 前替换备案域名:参见上面"4. 域名重置"。

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)

// 添加
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) {
    // ...
}];

// 查询单条
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);
    }
}];

// 更新(不预先 GET,直接构造 + objectId)
BmobObject *gs = [BmobObject objectWithoutDatatWithClassName:@"GameScore" objectId:@"0c6db13c"];
[gs setObject:@91 forKey:@"score"];
[gs updateInBackground];

// 删除
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
