SD图片处理---内存疯长的解决办法

之前遇到一个问题，大量高清图片显示的时候会出现手机内存疯长 导致app被系统kill，后来想到了一个解决办法 写在这里 记录一下。

#pragma mark --- 高分辨率的图片禁止图片解压缩操作
    [[SDImageCache sharedImageCache] setShouldDecompressImages:NO];
    [[SDWebImageDownloader sharedDownloader] setShouldDecompressImages:NO];
    
    SDImageCache *canche = [SDImageCache sharedImageCache];
    canche.shouldDecompressImages = NO;
    
    SDWebImageDownloader *downloder = [SDWebImageDownloader sharedDownloader];
    downloder.shouldDecompressImages = NO;

-(void)dealloc {
    SDImageCache *canche = [SDImageCache sharedImageCache];
    canche.shouldDecompressImages = YES;
    
    SDWebImageDownloader *downloder = [SDWebImageDownloader sharedDownloader];
    downloder.shouldDecompressImages = YES;
}

• 这样结合处理 就会解决内存的问题
