 ## Table of Contents
 
-## 一、The conditions of use
+## 1st、The conditions of use
 > * Minimum version iOS 8.0
 > * The Bluetooth version used by the device requires 4.0 and above.
-## 二、Use
-1. Apply the key and secret of sdk, application address: http://sdk.aicare.net.cn;
+## 2nd、Use
+1. Import TPSMSleSDK.framework into the Xcode project.
 2. Add "Privacy-Bluetooth Always Usage Description" to the info.plist file;
-3.Import TPSMSleSDK.framework into the Xcode project.
-4. Enter the following code in AppDelegate:
-```
-#import <TPMSBleSDK/ELTPMSBleManager.h>
-
-- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
-    // Override point for customization after application launch.
-    [ELTPMSBleManager setAppKey:@"key" appSecret:@"secret"];
-    return YES;
-}
-```
-5.Set the bitcode of the build setting to NO
-6.Import "#import <TPMSBleSDK/ELTPMSBleManager.h>" to the controller you want to use, and follow the "<ELTPMSBleManagerDelegate>" protocol.
-7.Set delegate
+3. Import "#import <TPMSBleSDK/ELTPMSBleManager.h>" to the controller you want to use, and follow the "<ELTPMSBleManagerDelegate>" protocol.
+4. Set delegate
 ```
 [ELTPMSBleManager shareManager].delegate = self;
 ```
-8.Implementing proxy method
+5.Implementing proxy method
 ```
  -(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
 -(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
 ```
    
-## 三、Get broadcast data
+## 3rd、Get broadcast data
 ### 1.Determine if the phone Bluetooth is available
 Proxy method：
 ```
  -(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
 ```
 This method is used to call back the TPMS Bluetooth module broadcast data. The model is an ELTPMSDataModel data model. For details on the ELTPMSDataModel class, please see "Remarks".
-## 四、Remarks
+## 4th、Remarks
 ELTPMSDataModel(Broadcast data model)

 ## 一、使用条件
 > * 最低版本iOS 8.0
 > * 设备所使用的蓝牙版本需要4.0及以上
 ## 二、开始使用
-1.申请sdk的key 和secret ,申请地址：http://sdk.aicare.net.cn；
+1.将 TPMSBleSDK.framework 导入Xcode工程;
 2.在info.plist文件中加入“Privacy - Bluetooth Always Usage Description”；
-3.将TPMSBleSDK.framework导入Xcode工程。
-4.在AppDelegate中入如下代码:
-```
-#import <TPMSBleSDK/ELTPMSBleManager.h>
+3.在需要使用的 控制器.m 中导入 #import <TPMSBleSDK/ELTPMSBleManager.h>，并遵守 < ELTPMSBleManagerDelegate> 协议;
+4.设置代理
 
-- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
-    // Override point for customization after application launch.
-    [ELTPMSBleManager setAppKey:@"key" appSecret:@"secret"];
-    return YES;
-}
-```
-5.设置build setting 的bitcode为NO
-6.在需要使用的控制器.m中导入#import <TPMSBleSDK/ELTPMSBleManager.h>，并遵守< ELTPMSBleManagerDelegate>协议，
-7.设置代理
 ```
 [ELTPMSBleManager shareManager].delegate = self;
 ```
 
-8.实现代理方法
+5.实现代理方法
+
 ```
- -(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
+-(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
 -(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
 ```
-   
+
 ## 三、获取广播数据
 ### 1.判断手机蓝牙是否可用
 可通过代理方法：
 -(void)TPMSBleManagerUpdateBleState:(TPMSBluetoothState)state;
 ```
 此方法用于获取蓝牙当前状态，其中参数”state”是一个枚举TPMSBluetoothState
-  枚举的元素包括：TPMSBluetoothStateAvailable（蓝牙打开可TPMSBluetoothStateUnavailable（蓝牙不可用），TPMSBluetoothStateBroadcasting（蓝牙正在广播数据），TPMSBluetoothStateStopBroadcasting（停止广播）
+枚举的元素包括：TPMSBluetoothStateAvailable（蓝牙打开可TPMSBluetoothStateUnavailable（蓝牙不可用），TPMSBluetoothStateBroadcasting（蓝牙正在广播数据），TPMSBluetoothStateStopBroadcasting（停止广播）
+
 ```
 -(void)TPMSBleManagerReceiveData:(ELTPMSDataModel *_Nonnull)model;
 ```
