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.plist加NSAppTransportSecurity → 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
