- 在项目根目录里建立文件:Podfile
- 输入内容:
platform :ios, '9.0'
target 'xxx' do //项目名
pod 'BmobSDK'
end
- 在项目根目录执行
pod install - 关闭xcode项目,重新进入项目根目录,点击编译后的文件打开
xxx.xcworkspace来打开项目 - 随便新建个oc文件,会出线提示是否新建桥接文件, 选择建立, 然后在 桥接文件 内加入
#import <BmobSDK/Bmob.h> - 在AppDelegate.swift注册申请的AppKey
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
// Override point for customization after application launch.
Bmob.register(withAppKey: "xxxxx")
return true
}
- 增删改方法:
//创建方法. 每次执行都会生成一个objectid, 供其他方法使用.
func save(){
let gamescore:BmobObject = BmobObject(className: "GameScore")
gamescore.setObject("赵三", forKey: "playerName")
gamescore.setObject(90, forKey: "score")
gamescore.saveInBackground { (isSuccessful, error) in
if error != nil{
print("error is \(error?.localizedDescription)")
}else{
print("success")
print(BmobObject())
}
}
}
//更新方法
func update() {
let gamescore:BmobObject = BmobObject(outDataWithClassName: "GameScore", objectId: "862b311786")
gamescore.setObject(1222, forKey: "score")
gamescore.updateInBackground { (isSuccessful, error) in
if error != nil{
print("error is \(error?.localizedDescription)")
}else{
print("success")
}
}
}
//删除方法
func deleteGameScore() {
let gamescore:BmobObject = BmobObject(outDataWithClassName: "GameScore", objectId: "4faf28f4dd")
gamescore.deleteInBackground { (isSuccessful, error) in
if error != nil{
print("error is \(error?.localizedDescription)")
}else{
print("success")
}
}
}
- 关于查询
- 如果知道某条数据的objectId，而且想得知该条数据的内容，可以使用Bmoquery检索得到一个完整的BmobObject
//查询单条数据
func searchOneData(){
let query:BmobQuery = BmobQuery(className: "yourDataBaseName")
query.getObjectInBackground(withId: "yourDataBaseID") { (ojj, error) in
if error != nil {
//进行错误处理
}else{
if ojj != nil{
let playerName = ojj?.object(forKey: "title")as? String
let url = ojj?.object(forKey: "url") as? String
print("playerName \(playerName),url \(url)")
print("objectid \(ojj?.objectId)")
print("createdAt \(ojj?.createdAt)")
print("updatedAt \(ojj?.updatedAt)")
}
}
}
}
* 根据表名,查询多条数据
func searchAllData() {
let query:BmobQuery = BmobQuery(className: "youhuiquan")
query.findObjectsInBackground { (array, error) in
var i = 0
while(i<(array?.count)!){
let obj = array?[i] as! BmobObject
let playerName = obj.object(forKey: "title") as? String
let url = obj.object(forKey: "url") as? String
print("playerName \(playerName)")
print("url \(url)")
print("objectid \(obj.objectId)")
print("createdAt \(obj.createdAt)")
print("updatedAt \(obj.updatedAt)")
i = i + 1
}
}
}
默认情况下，系统实际上并不会返回所有的数据，而是默认返回10条数据记录，你可以通过setLimit方法设置返回的记录数量。更多细节可点击查看查询一节中的分页查询。
- 当查询的是用户表这种系统表的时候，返回的是BmobUser的数组，设备表，角色表也是这样的。
- 查询用户表，设备表、角色表为：
let query:Bmoquery = BmobUser.query() //用户表let
query:Bmoquery = BmobInstallation.query() //设备表let
query:Bmoquery = BmobRole.query() //角色表
在ios端使用Bmob数据库里的图片
@IBOutlet weak var imageUI: UIImageView!
func searchOneImage(){
let query:BmobQuery = BmobQuery(className: "xxxxxx")
query.getObjectInBackground(withId: "xxxxx") { (ojj, error) in
if error != nil {
//进行错误处理
}else{
if ojj != nil{
//获取云数据库里image字段的内容
let image = ojj?.object(forKey: "image") as? BmobFile
//获取图片的url
let urlStr = NSURL(string: (image?.url)!)
//加载到ImageView控件
let data = NSData(contentsOf: urlStr! as URL)
self.imageUI.image = UIImage(data: data! as Data)
}
}
}
}
