如何从iСloud访问全尺寸图像？每次我尝试拍摄这张照片时,我都会得到256x342的图像尺寸.我也没有看到进展.

码:

    PHFetchResult *result = [PHAsset fetchAssetsWithLocalIdentifiers:@[assetIdentifier] options:nil];
    PHImageManager *manager = [PHImageManager defaultManager];
    [result enumerateObjectsUsingBlock:^(PHAsset *asset, NSUInteger idx, BOOL *stop) {

        PHImageRequestOptions *options = [[PHImageRequestOptions alloc] init];
        options.deliveryMode = PHImageRequestOptionsDeliveryModeHighQualityFormat;
        options.synchronous = YES;
        options.networkAccessAllowed = YES;
        options.progressHandler = ^(double progress, NSError *error, BOOL *stop, NSDictionary *info) {
            NSLog(@"%f", progress);
        };

        [manager requestImageForAsset:asset targetSize:PHImageManagerMaximumSize contentMode:PHImageContentModeDefault options:options resultHandler:^(UIImage *resultImage, NSDictionary *info)
         {
             UIImage *image = resultImage;
             NSLog(@"%@", NSStringFromCGSize(resultImage.size));
         }];
    }];

直到我点击照片应用程序中的图片,这张图片质量很差.但是一旦我点击图片,它就会在设备上下载,并且质量非常全.
