GPU高播放卡顿

[vviicc]

用Instrument调试发现播放多个svga时，GPU很高（50%-80%）， SVGAContentLayer stepToFrame:(NSInteger)frame self.mask = frameItem.maskLayer; 发现这里比较耗时，近期有没有性能优化的版本？

if ([SVGAVideoEntity isMP3Data:protoImages[key]]) { // mp3 [audiosData setObject:protoImages[key] forKey:key]; } else { UIImage *image = [[UIImage alloc] initWithData:protoImages[key] scale:2.0]; if (image != nil) { image = [image imageByResizeToSize:image.size]; [images setObject:image forKey:key]; } }

• (UIImage )imageByResizeToSize:(CGSize)size { if (size.width <= 0 || size.height <= 0) return nil; UIGraphicsBeginImageContextWithOptions(size, NO, self.scale); [self drawInRect:CGRectMake(0, 0, size.width, size.height)]; UIImage image = UIGraphicsGetImageFromCurrentImageContext(); UIGraphicsEndImageContext(); return image; }

调用这个imageByResizeToSize方法就能解决这个内存暴涨的问题。知道原因的话可以交流。
