在做一个全屏浏览本地相册的页面，但是滚动时会有卡顿 发现是跟 alasset 有关
先贴代码
- (void)loadImage
{
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0), ^
{
UIImage *image = [UIImage imageWithCGImage:[self.assetInfo.asset.defaultRepresentation fullScreenImage]];
dispatch_async(dispatch_get_main_queue(), ^
{
self.imageView.image = image;
});
});
}
会感觉到 fullScreenImage 读取图片的时候会卡顿
