      Integration Preparation

      1. Download and unzip the Demo package.
      2. Import the xmagic module (bundle, XmagicIconRes, Xmagic folder) from the Demo project into the actual project.
      3. If the version of XMagic SDK used is 2.5.0 or earlier, import libpag.framework, Masonry.framework, XMagic.framework, YTCommonXMagic.framework in the SDK directory. If the version of XMatic SDK used is 2.5.1 or later, import libpag.framework, Masonry.framework, XMagic.framework, YTCommonXMagic.framework, Audio2Exp.framework, TEFFmpeg.framework(version3.0.0 or later, renamed as:TECodec.framework) in the SDK directory.
      4. For framework signature, select Embed & Sign for General > Masonry.framework and libpag.framework. For YTCommonXMagic.framework, select Do Not Embed for versions before 2.5.1, and select Embed & Sign for versions 2.5.1 and later.
      5. Change the Bundle ID to match the issued authorization.

      Developer Environment Requirements

      Developer tools XCode 14 and later: Go to App Store or click Download link .
      Recommended runtime environment:
      Device requirements: iPhone 5 and above. For iPhone 6 and below, the front camera supports up to 720p, not 1080p.
      System requirements: iOS 10.0 and above.

      C/C++ Layer Development Environment

      Xcode uses the C++ environment by default.

      SDK API Integration

      For Step 1 and Step 2, please refer to the viewDidLoad and buildBeautySDK methods of the ThirdBeautyViewController class in the Demo project; The application method in the AppDelegate class contains code for authenticating Xmagic.
      From Step 4 to Step 7, please refer to the related sample code within the demo project's ThirdBeautyViewController, BeautyView class.

      Step 1. Initialize Authorization

      1. Firstly, add the following authentication code in AppDelegate's didFinishLaunchingWithOptions, where LicenseURL, LicenseKey are the authorization information obtained from Tencent Cloud's official website, please refer to Licenses:
      [TXLiveBase setLicenceURL:LicenseURL key:LicenseKey];
      2. Xmagic authorization: Set the URL and KEY in the initialization code of the relevant business module to trigger License Download, avoiding temporary download before using. Also, you can trigger the download in AppDelegate's didFinishLaunchingWithOptions method. The LicenseURL and LicenseKey are the authorization information generated when binding the License in the console. For SDK versions before 2.5.1, TELicenseCheck.h is within XMagic.framework; For SDK versions 2.5.1 and later, TELicenseCheck.h is within
      YTCommonXMagic.framework.
      [TELicenseCheck setTELicense:LicenseURL key:LicenseKey completion:^(NSInteger authresult, NSString * _Nonnull errorMsg) {
          if (authresult == TELicenseCheckOk) {
               NSLog(@"Authentication successful");
           } else {
               NSLog(@"Authentication failed");
           }
       }];
      Authentication errorCode Description:
      Error code
      Description
      0
      Successful
      -1
      Invalid input parameters. URL, KEY, etc. is empty.
      -3
      Download failed. Please check your network settings.
      -4
      The TE authorization information read from local is empty. It may be caused by IO failure.
      -5
      Content of VCUBE TEMP License file is empty. It may be caused by IO failure.
      -6
      JSON fields in the v_cube.license file are incorrect. Please contact the Tencent Cloud team for assistance.

      Download failed. Local asset parsing also failed.
      -13
      Authentication failed.
      Other
      Please contact the Tencent Cloud team for assistance.

      Step 2. Set the SDK Material Resource Path

      - (void)buildBeautySDK:(int)width and:(int)height texture:(unsigned)textureID {
          NSDictionary *assetsDict = @{@"core_name":@"LightCore.bundle",
                                       @"root_path":[[NSBundle mainBundle] bundlePath]};
          // Initialize SDK: 'width' and 'height' are respectively the width and height of the texture.
         self.xMagicKit = [[XMagic alloc] initWithRenderSize:CGSizeMake(width,height) assetsDict:assetsDict];
      }

      Step 3. Add the Log and Event Listener

          // Register log
          [self.beautyKit registerSDKEventListener:self];
          [self.beautyKit registerLoggerListener:self withDefaultLevel:YT_SDK_ERROR_LEVEL];

      Step 4. Configure Effects

      - (int)configPropertyWithType:(NSString *_Nonnull)propertyType withName:(NSString *_Nonnull)propertyName withData:(NSString*_Nonnull)propertyValue withExtraInfo:(id _Nullable)extraInfo;

      Step 5. Render Videos

      In the video frame callback interface, construct YTProcessInput and pass it to the SDK for rendering processing. Refer to 'ThirdBeautyViewController' in the Demo.
      [self.xMagicKit process:inputCPU withOrigin:YtLightImageOriginTopLeft withOrientation:YtLightCameraRotation0]

      Step 6. Pause/Resume the SDK

      [self.beautyKit onPause];
      [self.beautyKit onResume];

      Step 7. Add the SDK Effect Panel to the Layout

      UIEdgeInsets gSafeInset;
      #if __IPHONE_11_0 && __IPHONE_OS_VERSION_MAX_ALLOWED >= __IPHONE_11_0
      if(gSafeInset.bottom > 0){
      }
      if (@available(iOS 11.0, *)) {
          gSafeInset = [UIApplication sharedApplication].keyWindow.safeAreaInsets;
      } else
      #endif
          {
              gSafeInset = UIEdgeInsetsZero;
          }
      
      dispatch_async(dispatch_get_main_queue(), ^{
          // Effect option UI
          _vBeauty = [[BeautyView alloc] init];
          [self.view addSubview:_vBeauty];
          [_vBeauty mas_makeConstraints:^(MASConstraintMaker *make) {
              make.width.mas_equalTo(self.view);
              make.centerX.mas_equalTo(self.view);
              make.height.mas_equalTo(254);
              if(gSafeInset.bottom > 0.0){  // Adapt to full-view screen
                  make.bottom.mas_equalTo(self.view.mas_bottom).mas_offset(0);
              } else {
                  make.bottom.mas_equalTo(self.view.mas_bottom).mas_offset(-10);
              }
          }];
          _vBeauty.hidden = YES;
      });
