##2013.10.16 update

• Compatible with new API(new attributes, landmarks etc.)

##2.0 update

• Compatible with 2.0 API
• Modify the initialize function to change region between CN and US
  • Example: [FaceppAPI initWithApiKey: @"YOUR_KEY" andApiSecret: @"YOUR_SECRET" andRegion: API_SERVER_REGION]

##To integrate FacePlusPlus SDK into your iOS project

1. In the finder, drag FaceppSDK into project's file folder.

2. Add it to your project:

   • File -> Add Files to "your project"
   • Choose 'Recursively create groups for any added folders'

3. In xcodeproj -> Build Settings, set "Objective-C Automatic Reference Counting" to NO

   • If you want to use automatic reference counting, you can use "FaceppSDK_ARC" instead of "FaceppSDK" which in step 1&2.

4. In your Application Delegate:

   • Import FaceppAPI
   • Add: [FaceppAPI initWithApiKey: @"YOUR_KEY" andApiSecret: @"YOUR_SECRET"]
   • Sample code:

   \#import "FaceppAPI.h"
    \- (BOOL)application:(UIApplication \*)application didFinishLaunchingWithOptions:(NSDictionary \*)launchOptions {
    	[FaceppAPI initWithApiKey:API_KEY andApiSecret:API_SECRET];
    	...
    }

5. Call FaceppAPI to do anything you want, it will return a struct called FaceppResult

   • Examples:

   FaceppResult\* result = [[FaceppAPI detection] detectWithURL:nil 
    						imageData:[NSData dataWithContentsOfFile:@"LOCAL_FILE_PATH"]];
   

FaceppResult* result = [[FaceppAPI group] deleteWithGroupName: @"GROUP_NAME" orGroupId: nil]; 6. Get value from FaceppResult - Examples: - Get image's width in pixel from a detection result - detectLocalFileResult:

double img_width = [[detectLocalFileResult content][@"img_width"] doubleValue];

- Get the first face_id from result:

NSString *face_id = [detectLocalFileResult content][@"face"][0][@"face_id"];

7. Optional: enable debug mode
   • Set debug mode on to display all http request packages and response raw JSON result on console output.

     [FaceppAPI setDebugMode: TRUE];

##您只需要做以下几个步骤就可以将FacePlusPlus SDK集成到您的iOS工程中

1. 在finder中，将FaceppSDK目录拖入工程目录下

2. 将FaceppSDK添加至您的工程中

   • 在菜单中选择File -> AddFiles to "YOUR_PROJECT"
   • 将'Recursively create groups for any added folders'选项钩上

3. 在工程设置文件中的Build Settings内，将**"Objective-C Automatic Reference Counting"设置为NO**

   • 注：如果需要使用自动引用计数，请用FaceppSDK_ARC替换FaceppSDK，并重新执行步骤1和2

4. 在您的应用程序入口处添加以下代码：

   • import FaceppAPI
   • 添加[FaceppAPI initWithApiKey: @"YOUR_KEY" andApiSecret: @"YOUR_SECRET"]
   • 举例来说，具体工程入口的代码如下所示:

   \#import "FaceppAPI.h"
    \- (BOOL)application:(UIApplication \*)application didFinishLaunchingWithOptions:(NSDictionary \*)launchOptions {
    	[FaceppAPI initWithApiKey:API_KEY andApiSecret:API_SECRET];
    	...
    }

5. 使用 FaceppAPI接口来调用任何您想调用的接口，在获得数据以后其将返回一个FaceppResult结构 －例子：

   FaceppResult\* result = [[FaceppAPI detection] detectWithURL:nil 
    						imageData:[NSData dataWithContentsOfFile:@"LOCAL_FILE_PATH"]];
   

FaceppResult* result = [[FaceppAPI group] deleteWithGroupName: @"GROUP_NAME" orGroupId: nil];

6. 从FaceppResult中获取结果：

   • 例子:
     • 从返回的检测结果(detectLocalFileResult)中获得图像的宽度：

   double img_width = [[detectLocalFileResult content][@"img_width"] doubleValue];

    - 获得第一张脸的face_id：
    	<pre><code>NSString \*face_id = [detectLocalFileResult content][@"face"][0][@"face_id"];</code></pre>
   

7. 使用调试模式：

   • 开启调试模式之后，程序将向控制台输出所有http请求的url，以及返回json的原始数据，以供调试使用。

     [FaceppAPI setDebugMode: TRUE];
