#import <PINRemoteImage/UIImageView+PINRemoteImage.h>

UIImageView *imageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 100, 100)];
NSURL *imageURL = [NSURL URLWithString:@"https://example.com/image.jpg"];

[imageView pin_setImageFromURL:imageURL completion:^(PINRemoteImageManagerResult *result) {
    if (result.requestDuration < 0.1 && result.resultType == PINRemoteImageResultTypeDownload) {
        // 图像是从缓存加载的，可以立即设置色调
        imageView.image = [result.image pin_transformedImageWithColorEffect:[UIColor redColor]];
    } else {
        // 图像是从网络加载的，需要等待加载完成后再设置色调
        [result.image pin_transformWithColorEffect:[UIColor redColor] completion:^(UIImage *transformedImage) {
            imageView.image = transformedImage;
        }];
    }
}];
