* [ ] 設置代理對象 遵循TXVideoCustomProcessDelegate // 推流器初始化 ``` TXLivePush?*pusher = [[TXLivePush alloc] initWithConfig:config]; pusher.videoProcessDelegate= self; ``` l在代理方法即視頻渲染方法中賦值，如下所示： ``` - (GLuint)onPreProcessTexture:(GLuint)texture width:(CGFloat)width height:(CGFloat)height{ int newTexture = [self.beautyManager getTexrureProcessWithTexture:texture width:width height:height]; return newTexture; } ``` 說明： 1.如果是開啟直播有鏡像效果的話，設置 ``` [_txLivePublisher setMirror:YES]; ``` 如果初始化美顏UIisTXSDK參數傳入的是YES，則需要實現騰訊的美顏方法，具體如下： ``` #pragma mark - MHMenuView Delegate - (void)beautyEffectWithLevel:(NSInteger)beauty whitenessLevel:(NSInteger)white ruddinessLevel:(NSInteger)ruddiness { ? ? TXBeautyManager?*manager = [_pushergetBeautyManager]; [manager setBeautyStyle:TXBeautyStyleSmooth]; [manager setBeautyLevel:beauty]; [manager setWhitenessLevel:white]; [manager setRuddyLevel:ruddiness]; } ``` 如果isTXSDK傳入NO，則不需要實現該代理方法，則走的是美狐的美顏方法。 2.如果需要適配性能較低手機，需要更換成以下調用方式 1.在ViewController中添加布爾值BOOL _needScale; 2.在ViewController中添加checkDeivice方法： ``` ?- (void)checkDevice{ /*獲取當前機型，判斷是否為 iPhone7 及以上*/ struct?utsname systemInfo; uname(&systemInfo); NSString *platform = [NSString stringWithCString:systemInfo.machine encoding:NSUTF8StringEncoding]; NSArray *symbols = [platform componentsSeparatedByString:@","]; if(symbols.count > 0){ NSCharacterSet *characterSet = [[NSCharacterSet decimalDigitCharacterSet] invertedSet]; NSInteger number = [[[symbols[0] componentsSeparatedByCharactersInSet:characterSet] componentsJoinedByString:@""] integerValue]; //iPhone9,1 -> iPhone 7 if(number >= 9){ _needScale = NO; }else{ _needScale = YES; } } } ``` 3.在回調中判斷是否需要縮放 ``` -(GLuint)onPreProcessTexture:(GLuint)texture width:(CGFloat)widthheight:(CGFloat)height{ GLuint newTexture = texture; if?(_needScale){ newTexture = [_beautyManager processWithTexture:texture width:width height:height scale:0.75]; }else{ [self.beautyManager processWithTexture:texture width:width height:height]; } return?newTexture ; } ```
